The BTO ballot result comes in and it is another queue number in the thousands. The COE for a small car costs what a flat deposit used to. Your kid's tuition centre sends the term invoice, your parents need a bit more each month, and the chicken rice that was cheap at uni now costs noticeably more.
In a city this kiasu, everyone seems to be moving ahead. A colleague mentions her rental unit. A friend leaves the bank for his own regional consultancy. Then your company announces a "reorganisation" and you scroll LinkedIn on the MRT home. Retrenchment here comes politely and fast, and AI is coming for the analyst work that once looked secure.
The upside is already in your hands. Your CPF statement shows an Ordinary Account at 2.5%, a Special Account at 4% toward retirement, a Medisave account at 4%, and later a Retirement Account at 4% with the first S$30K bonused up to 6%. Above that floor sits the part people move here for: 0% tax on capital gains, 0% tax on most dividends, a top income tax rate of 22-24%, and roughly 1 in 6 Singaporean households already holding USD millionaire status (Henley Global Wealth Report 2025). Each year that 0% sits unused is a year of tax-free compounding gone.
Reaching $60,000 a year of income on top of your salary takes 6 to 24 months here, and you can begin at zero cost, though a serious setup runs to $10,000.
Your step today is small: log in, write down the balance in each CPF account, and note which one you have never once looked at.
"Singapore" also plays out differently depending on who you are. The path that works if you are a 24-year-old NUS grad in tech (max CPF, SRS, build a regional SaaS) looks very different from the one that works if you are a 38-year-old PMET with a HDB and two kids (REIT income ladder, SA shielding, a side business on top). This guide walks you through the four pillars of Singapore wealth-building in 2026, and exactly which one you should start with.
Every wealthy Singaporean (local-born, PR, or expat) sits on some mix of these four engines:
Skip pillar 1 (the tax shelter) and you are voluntarily handing IRAS up to 22% of every pay rise you get. Skip pillar 2 (the capital gains structure) and you are paying foreign tax that people here legally avoid. Most expats, and plenty of locals, miss both.
Which of the four are you already running without really thinking about it, and which have you never touched? Most readers find they are strong on one and absent from two, and the gap usually points straight at your first move.
You have now seen the four CPF accounts from the outside. This pillar moves whether or not you do anything clever with the rest, which is why it goes first.
Almost everyone outside Singapore misunderstands the CPF (Central Provident Fund). Think of it as a forced savings account that pays you 2.5-6% guaranteed returns, set aside for your retirement, healthcare and housing. For 2026:
What is your marginal rate this year? If it is 11.5% or higher, step 4 is probably the single highest-return thing you can do before December, and it takes an afternoon.
If you want the mechanics, our ETF Investing and Dividend Investing guides walk you through the specific tickers and brokers.
There is a homely way to read a 4-7% yield. If REIT dividends land untaxed each quarter on a sum large enough, they can become the line that pays for your kids' swimming lessons and the school camp, while your salary handles the mortgage and CPF. Work out what 4-7% means on the amount you can actually invest before you count on it.
Singapore's public housing system (HDB) is subsidised like few others. ~80% of citizens live in HDB flats, and if you are a first-time buyer couple you can stack:
After the grants, a typical 4-room BTO in a non-mature estate costs S$350K-S$500K. It is financed by an HDB concessionary loan (2.6% pegged to CPF-OA + 0.1%), with CPF-OA covering most monthly instalments. That means many young couples buy a S$500K asset with effectively zero cash outlay; you need no tenants because CPF carries the instalments.
After the 5-year Minimum Occupation Period (MOP), you can sell tax-free (0% capital gains) and upgrade to a private condo. It is a path called the "HDB to condo upgrade", and many Singapore millionaires have ridden it.
Private property in 2026 is harder: ABSD (Additional Buyer's Stamp Duty) hits 20% for second properties for citizens, 30% for PRs, 60% for foreigners. Pure investment property only makes sense for high-net-worth households. If you are under 40, focus on HDB first, use REITs for property exposure, and skip private until your household income clears S$200K.
Would you rather have your wealth tied up in the flat you live in, or spread across REITs you can sell in a day? There is no single right answer, though knowing yours before your MOP ends makes the upgrade decision far calmer.
Everything up to here works on capital, whether it is yours or borrowed. What sets the speed of all of it is how much arrives in your account each month, so that is what this pillar is for.
Investing S$1,000/month makes you wealthy by 65. Investing S$5,000/month makes you wealthy by 45. Your income makes that difference, and your choice of investments matters far less.
As soon as a regional skill or a Shopee store is paying you a steady surplus, the first thing it can buy is your parents' rest. Taking over their utilities and phone bills each month, and telling your dad he can stop the extra evening shifts, is a return that never shows up in a brokerage statement. Work out how much of his shift income that replaces before you ask him to give it up.
Think of the smaller wins too. Paying for your kid's enrichment class without choosing between that and the year-end trip to Japan. Moving from the HDB flat to a condo on your own timeline. Flying to Bali for your best friend's wedding without checking your card statement first.
Singapore tax rates feel low (2-22%, capped at 24% for income above S$500K), and the legal toolkit for lowering your bill is substantial:
If you earn over S$200K and you do not have an accountant who knows the SRS / RA / Pte Ltd structure, you are probably leaving S$5,000-S$15,000 on the table every April.
How many of the reliefs in that table did you claim last year? Open your last IRAS assessment tonight and tick them off; any blank row is money you can still plan for this year.
2026 Market Snapshot
Singapore's wealth-building landscape in 2026 sits at an unusual crossroads. The Straits Times Index is up 14% year-to-date (April 2026) on bank earnings strength, S-REITs have rebounded sharply as the Fed cuts global rates, and inbound family-office wealth has grown a further 18%. Singapore is now home to over 2,000 single-family offices, double the 2022 figure (MAS data).
| Measure | Figure | Note |
|---|
| Household net worth | S$2.9 trillion | as of Q4 2025 (MAS Household Sector Report) |
| Median household net worth | S$580,000 | the highest in Asia outside the Gulf |
| Millionaire density | 1 in 6 households | (Henley & Partners 2025) |
| Singapore Savings Bonds yield | ~3.0% | for 10-year (April 2026 issue) |
| 3-month T-bill cut-off | ~3.4% | risk-free cash is genuinely useful again |
| HDB resale price index | up 5.1% YoY | sustainably moderating from 2022-2023 spike |
Where does your own household sit against that S$580,000 median? Add up your CPF, cash, investments and home equity once, roughly, and you will know whether you are catching up or building on a lead.
Key Players to Watch
These are the names that will shape your options as a Singapore saver and earner:
- DBS / OCBC / UOB: the local bank trio; DBS Vickers and OCBC Securities still dominate retail brokerage
- Endowus: the breakout local fintech for cash + CPF + SRS investing into Dimensional, PIMCO, and Vanguard funds
- Stashaway / Syfe: robo-advisor pioneers, both pivoting to higher-fee thematic and managed portfolios
- Tiger Brokers SG / moomoo / IBKR: the cheap-trade brokers for US and Hong Kong markets
- Sea Group / Grab / Shopee: listed regional tech incumbents whose stock options have minted thousands of paper millionaires
- CapitaLand / Mapletree / Keppel: the REIT sponsors that anchor most local dividend portfolios
- Adam Khoo / Investment Moats / Dr Wealth / Financial Horse / Seedly: the local creator and community ecosystem
- Henley Private Wealth Migration Report: tracks the inflow of HNW migrants choosing Singapore over Hong Kong, London, and the UAE
Predictions for 2026-2027
- The family office boom continues. MAS's Section 13O/13U regimes have made Singapore the second-largest single-family office hub globally after Switzerland. Expect the count to cross 2,500 by end-2027, pushing up demand for compliance, tax and investment advisory roles you might fill.
- S-REITs reprice higher. With the Fed cutting and Singapore inflation back to ~2%, the average S-REIT distribution yield (~6.0% in early 2026) is too generous next to 3% T-bills. Expect a 10-15% capital appreciation through 2027 as the gap closes.
- HDB BTO supply normalises. HDB's accelerated launch programme delivers 100,000+ flats by end-2027, easing the pressure-cooker resale market. Resale prices flatten or dip slightly, then go back to 3-4% annual growth.
- AI-driven solo businesses scale from Singapore. Singapore's English-speaking, regulated, low-tax structure suits solo founders running global-facing AI agencies, SaaS and content businesses. Expect 5-10K new Pte Ltds incorporated by individual creators in 2026.
- More foreign tech founders relocate. Hong Kong's instability, India's tax friction and California's exit taxes are pushing founders to Singapore via Tech.Pass, EntrePass and ONE Pass. That adds talent density and exit liquidity to the local startup market you would be building in.
Each of those shifts favours people already in position. Family offices hire people with track records, and solo founders who incorporate early meet the clients first. Leave your savings in a fixed deposit while this plays out and you watch others collect the upside from the same island, under the same tax rules.
Emerging Opportunities
Family office adjacent services. The 2,000+ single-family offices need compliance, tech, lifestyle management and investment advisory. Service businesses billing S$300-S$1,000/hour are the fastest-growing high-margin niche in Singapore right now.
Regulated crypto. Singapore's MAS framework gives DBS Digital Exchange, Independent Reserve, Coinhako and licensed Singapore desks regulatory clarity that most places lack. With 0% capital gains on crypto for individuals, holding BTC/ETH long-term in a Singapore wallet is one of the most tax-efficient setups in the world, though the price risk stays entirely yours.
SEA cross-border SaaS. Singapore-incorporated companies enjoy double tax treaties with 90+ countries. Building SaaS for Indonesia (280M people), Vietnam and the Philippines from a Singapore Pte Ltd is structurally favourable for bringing cash home and holding IP.
Geographic arbitrage in reverse. If you are a Singaporean knowledge worker earning USD or EUR while spending SGD on essentials, you still get more "real" purchasing power per hour than peers in San Francisco or London, once tax, healthcare and rent are factored in. Remote work is a wealth lever Singapore residents underuse.
Could your current skill be billed to a family office at S$300 an hour? If you work in compliance, tax, tech or wealth management, list three family offices you could reach through people you already know.
Common Objections & Counterarguments
"Singapore is too expensive. I cannot save here." Median household income (S$11K/month) supports a 30%+ savings rate even with HDB, MRT and hawker centre living. The cost of living is high in absolute terms and moderate relative to income. The expensive lifestyle (private condo, car, branded everything) is something you choose, and you can choose otherwise.
"The market is too high to invest now." S-REITs and global ETFs both trade well within their long-run valuation bands in 2026. Time in the market beats timing the market: automate your Endowus or Syfe contributions and never look at prices.
"I missed the wealth-building window because I'm 40+." The median age of Singaporean first-time millionaires (by household) is in the late 40s. CPF Life plus SRS plus a paid-off HDB does most of the heavy lifting after age 55. The maths still works for you. It just asks for a 25-30% gross savings rate.
"AI will eliminate the high-income skills." Historically, technology shifts displace specific job categories and raise overall wages. Singapore's strategy is to be early on AI adoption (TechSkills Accelerator, AI Apprenticeship Programme, S$1B national AI plan). For you personally, failing to upskill into AI-augmented work is a bigger risk than the AI itself.
Tax, registration and CPF when you earn on the side
Singapore's reputation as a low-tax place is largely accurate, and the detail is worth knowing precisely, because the specific thresholds are unusually kind to a small operator like you and unusually easy to misjudge.
Your residency decides your rates before anything else
The Inland Revenue Authority of Singapore treats you as a tax resident if you are a Singapore citizen or permanent resident living here apart from temporary absences, or a foreigner who has stayed or worked in Singapore for at least 183 days in the previous calendar year, or continuously for three consecutive years, or across two calendar years with a total stay of at least 183 days. Fail those tests and you are taxed as a non-resident, on a different and generally worse basis.
If you are building a side income here, resident status is the assumption, and it is what the rates below apply to.
The rates, and the part that matters most to you
Resident individual income tax is progressive, and the current top rate is 24%. From Year of Assessment 2024 onwards, IRAS publishes the schedule as:
| Chargeable income | Rate on that band |
|---|
| First $20,000 | 0% |
| Next $10,000 (to $30,000) | 2% |
| Next $10,000 (to $40,000) | 3.5% |
| Next $40,000 (to $80,000) | 7% |
| Next $40,000 (to $120,000) | 11.5% |
| Next $40,000 (to $160,000) | 15% |
| Next $40,000 (to $200,000) | 18% |
| Next $40,000 (to $240,000) | 19% |
| Next $40,000 (to $280,000) | 19.5% |
| Next $40,000 (to $320,000) | 20% |
| Next $180,000 (to $500,000) | 22% |
| Next $500,000 (to $1,000,000) | 23% |
| Above $1,000,000 | 24% |
The first $20,000 of chargeable income is taxed at nothing, and the next $20,000 at 2 and 3.5%. If you are testing a side business, that is close to a tax holiday in your early years. A venture producing $30,000 of chargeable income pays $200 in tax.
Compare that with the treatment described in this site's Australia guide, where side income stacks on top of salary at a marginal rate of 30% or more from a low threshold, and you can see how much faster a small business can build capital here.
Rebates have applied in some years. For Year of Assessment 2025 a personal income tax rebate of 60% of tax payable, capped at $200, was granted to tax residents. Rebates are announced each year, so please do not assume one.
GST: the threshold you will probably never reach
You must register for GST if your taxable turnover exceeds $1 million, assessed either retrospectively at the end of the calendar year or prospectively where you expect to exceed it in the next 12 months.
That threshold is more than thirteen times Australia's, and the practical result is simple: the overwhelming majority of side businesses in Singapore never register for GST at all. No GST on your invoices, no quarterly returns, no reclaiming input tax. It is one of the simplest small-business environments you will find anywhere.
Voluntary registration is possible and occasionally worth it if you sell mainly to other GST-registered businesses while carrying significant input tax. For most of you reading this, it would be an unnecessary compliance burden.
Registering your business
You register a sole proprietorship with ACRA through BizFile, and the fees are modest. It is the right starting point for testing an idea.
A private limited company is a separate legal person, taxed at the corporate rate of 17% on chargeable income, with start-up and partial tax exemption schemes that cut the effective rate substantially in the early years. The question of when to switch is the same as anywhere: incorporate when profits consistently exceed what you need to draw, when your liability risk is real, or when you take on a partner or investor.
One Singapore-specific point. A sole proprietorship's profits are your personal income, taxed at the progressive rates above, so a modest side business will often pay less tax as a sole proprietorship than as a company. The company becomes attractive later than most people expect.
If your side business made $30,000 this year, which band in that table would it land in once added to your salary? That one number tells you more about your real tax cost than any general claim about Singapore being low tax.
CPF and your MediSave obligation
This is the item most first-time self-employed people in Singapore miss.
As an employee, your CPF contributions come out of payroll automatically and your employer pays in alongside you. Once you are self-employed, most of that disappears, with one compulsory exception.
MediSave contributions are compulsory for self-employed persons once net trade income passes a threshold, reported at $6,000 a year, with contribution rates in the region of 9% of net trade income and caps that vary with your age and income. CPF publishes a self-employed MediSave contribution calculator, and that calculator is the authority for your own figure, ahead of any rule of thumb.
Two things follow.
You declare net trade income to IRAS by filing your tax return, and you make no separate declaration to the CPF Board. What you tell IRAS triggers the obligation.
Budget for it. Nobody withholds it and it arrives as a bill. If you set nothing aside, you meet both the income tax and the MediSave liability in the same period.
Beyond the compulsory portion, contributing voluntarily to CPF earns tax relief within limits. If you leave employment for self-employment and stop contributing entirely, you have quietly stepped off the country's main retirement savings mechanism, the same trap described for Australian sole traders and superannuation.
The trade Singapore offers you, and what it costs
Singapore's economics are unusual enough that strategies which work elsewhere often fail here, and strategies that fail elsewhere work unusually well. It helps to spell the trade out plainly.
A tiny home market attached to an enormous regional one
Singapore's population is under six million. If your plan is to serve Singapore residents, you are building for a market smaller than a single mid-sized city elsewhere, and niches fragment fast. A specialism that supports a comfortable business in the United States may support one or two operators here.
The upside is position. Singapore sits inside a region of hundreds of millions of people, in a timezone that covers most of Asia and overlaps the end of the European day, with English as the working language, a legal system businesses trust, and banking and payment infrastructure that works.
Put together, that points to one conclusion, and it is the most important strategic sentence on this page for you: build for the region, base yourself here.
The businesses that thrive fit this shape.
Services sold across borders. Consulting, design, software, content and any professional service delivered remotely. You sell into a large market while enjoying local tax treatment and infrastructure.
Businesses that need trust as an input. Cross-border trade, fintech, and anything where a counterparty needs confidence in contract enforcement. A Singapore entity is a credibility signal that carries real weight across the region.
Operations coordinating a wider footprint. Managing suppliers or teams across Southeast Asia is far easier from here than from outside.
The businesses that struggle share the opposite shape: anything competing on cost, anything that needs cheap space, and anything whose entire market is the resident population.
Who outside Singapore would pay for what you already do at work? If you can name a buyer in Jakarta, Manila or Ho Chi Minh City, you have the start of a business that fits this shape.
The cost side is real, and it is your main constraint
Singapore is expensive, and the expense lands exactly on the inputs a new business needs.
Space is the hard limit. Commercial rent is high and residential space is tight. Any model that needs square metres, whether retail, storage, workshop, studio or fulfilment, carries a cost base here that would be a rounding error in most countries. This is the single biggest reason an idea that works elsewhere fails in Singapore.
Labour is expensive and shaped by policy. Beyond wages, hiring foreign workers involves passes, quotas and levies depending on the role, and those are policy tools that change. If your plan depends on hiring cheaply from abroad, it is exposed to policy risk.
Your personal cost of living raises your floor. Housing and a car in particular mean the income you need before a business is viable is high. That shortens your runway and raises the bar on what counts as a worthwhile venture.
The answer is the same across all three. Prefer businesses with low fixed costs and high margins, which in practice means services, software and digital products over anything physical. Then use the low tax rates to compound what you keep.
What to do with the money once it works
Singapore's favourable tax treatment reaches well beyond income. Two features shape wealth building here, and both are covered further up this page, but they connect to the earning side in a way worth stating.
There is no capital gains tax in Singapore. Investment returns are generally not taxed as gains, which changes the arithmetic of holding assets a great deal compared with markets that tax disposals.
CPF gives you a floor with a guaranteed return, and the tax relief on voluntary contributions makes it more attractive than its headline rates suggest once you have taxable income.
Read alongside the income tax schedule, your sequence as a self-employed person is fairly clear. Keep chargeable income low in the early years, where the rates are near zero anyway, meet the compulsory MediSave obligation, use voluntary CPF contributions for the tax relief once you are into the higher bands, and hold your investments where the gains are untaxed.
That is an unusually good set of conditions for building capital from a small business, and it makes the small home market a price well worth paying.
Licensing, employment status and the rules that catch people
That settles the money side. What follows decides whether you are allowed to do it the way you have just planned.
There are three areas where Singapore is stricter than its business-friendly reputation suggests, and where the penalties are real.
Regulated activities need a licence, and the list is longer than you think
Singapore regulates carefully, and several activities that feel like ordinary side hustles need authorisation.
Financial advice and dealing in capital markets products are licensed by the Monetary Authority of Singapore. Running a paid signals channel, managing money for others, or advising on investments for a fee puts you in territory where you need to know exactly where the boundary is before you charge anyone. The same warning given on this site's trading and community pages applies with force here, because enforcement is active.
Payment services, including dealing in digital payment tokens, require licensing under the Payment Services Act. A business that holds or moves other people's money is a regulated business from day one, however small it feels to you.
Food, private education, employment agency work, moneylending, security services, travel agency and public entertainment all carry their own licensing regimes.
The general rule: if your activity involves other people's money, other people's safety or other people's children, assume it is licensed and check before you begin. Operating without a required licence here is treated as a serious offence, far beyond missing paperwork.
Does the side business you have in mind touch anyone else's money, safety or children? If it does, a short check on the relevant agency's website before your first client could save you from the penalties described above.
You do not get to choose employment status
Engaging someone as a freelancer to keep costs down is common and often done wrongly. Where the substance of the relationship is employment, the obligations of employment follow, including CPF contributions for citizens and permanent residents, and the protections of the Employment Act.
Getting this wrong exposes you to back contributions and penalties. As with the Australian position described in the sister guide, the test looks at the reality of the arrangement over the wording of the agreement.
Data and marketing rules bind small operators too
The Personal Data Protection Act applies to organisations of any size, including a one-person business collecting email addresses. The obligations that most often catch people are consent for collection and use, allowing withdrawal of consent, protecting what you hold, and appointing a data protection officer.
Separately, the Do Not Call registry governs marketing messages to Singapore telephone numbers. Sending marketing texts or calls to numbers on the register without the required checks and consent attracts penalties, and this is enforced. If you run any outreach business of the kind described elsewhere on this site, understand it before your first campaign here.
The pattern worth taking to heart
Singapore's bargain is consistent: low taxes and excellent infrastructure in exchange for taking the rules seriously. Compliance is generally cheap, fast and digital, and non-compliance is dealt with firmly.
That is a good trade if you are building a legitimate business, and a poor place for anyone hoping regulation will be loosely enforced. Decide which of those describes your plan before you commit to it.
Your twelve-month sequence
You know what to set up and you know what could stop you. The open question is the order, and when each piece should start.
Here is the order that works if you are starting from employment in Singapore.
Before you earn. Check whether what you plan to sell is licensed, using the rule above. Choose a sole proprietorship over a company unless you already have a specific reason for the company, because the progressive personal rates on early profits beat the corporate rate for most small ventures.
On your first client. Register your sole proprietorship with ACRA through BizFile. Open a separate bank account. Keep every invoice and receipt from the very first one, because the record-keeping expectation applies from the beginning and rebuilding it later is the same misery it is anywhere.
Through the first year. Track your net trade income against the MediSave threshold so the obligation does not catch you by surprise, and use CPF's self-employed calculator instead of estimating. Ignore GST unless you are genuinely approaching a million dollars of turnover, which you almost certainly are not. Set money aside for tax even though the early bands are low, because at this stage the habit matters more than the amount.
At filing. Declare your net trade income to IRAS in your tax return, which also triggers the MediSave assessment. If you have both employment and self-employment income, remember they combine into one chargeable income figure and one progressive calculation.
Once profits are consistent. Revisit the company question against liability and rate. Start voluntary CPF contributions for the relief once you are in the higher bands. Then move your surplus into investments and let the absence of capital gains tax do the compounding, which is the pillar this page opened with.
The whole sequence is light on admin by international standards. That is the point of being here.
What would it mean for you if work became optional years earlier than you assumed? Keep that picture in mind when the twelve months feel slow.
Run this sequence for twelve months and then keep it running, and the arithmetic starts moving your retirement date. If your SRS is filled to S$15,300 each year and the surplus compounds with no capital gains tax, the age at which work becomes optional for you can edge earlier. The top of this range is rare, and the habit that points toward it is open to anyone with a payslip.
Waiting feels safe in Singapore, which is exactly why it costs so much. Each year you skip the SRS top-up, that year's tax relief is gone for good, and every idle year of savings is compounding you never get back. Log in to your CPF and SRS accounts tonight and pick one move to make before December.
Reading foreign advice from Singapore
Most side-income material online is written for the United States, and four of its background assumptions fail here. Knowing which ones saves you from rebuilding your plan around the wrong constraints.
Tax drag on early profits. American content assumes self-employment tax and federal plus state income tax from the first dollar of profit. Singapore's first $20,000 of chargeable income is taxed at nothing. A business that looks marginal in a US case study can be comfortably worthwhile for you here, because a much larger share of early profit survives.
Sales tax complexity. US content spends real attention on registering and remitting sales tax across states. With a GST threshold of a million dollars, this is a non-issue for almost everyone reading this page. Skip it.
Health insurance as the cost of independence. A recurring theme in American advice is that leaving a job means buying medical cover privately, which raises the bar on what a business must earn. Singapore's system changes that calculation for you, and MediSave contributions, while compulsory, go into your own savings instead of vanishing as a premium each month.
Market size. This one runs the other way, and it matters most. American case studies assume a home market of hundreds of millions. A niche described as small there may not exist here at all. Always ask whether the numbers in a case study depend on domestic scale, and if they do, either plan for regional distribution from the start or pick a different niche.
The general method is the one recommended in the Australia guide. Take the mechanics from wherever they are best explained, then rebuild every number from local inputs before you believe the conclusion. The operational advice usually carries over intact. The arithmetic almost never does, and in Singapore's case it often carries over in your favour.
Singapore revises thresholds and reliefs at each Budget, and rebates in particular are announced year by year, so none of them is permanent.
Every number on this page is cited to the agency that sets it. Before you act on a threshold, open the IRAS or CPF page yourself and trust it over any summary, including this one. That habit is the practical difference between a plan that survives filing season and one that falls apart in it.
A worked example makes this concrete. Say you are employed on $80,000 and you build a side business to $30,000 of net profit. You do not pay a separate business tax on that $30,000. It is added to your employment income, and the combined figure runs through the single progressive schedule above. The band that extra profit lands in decides what it costs you, which is why knowing your own position on the table matters more than any general statement about Singapore being low tax.
