Sole Proprietorship vs Pte Ltd Singapore: Tax, Break-Even Profit and When to Incorporate

Sole proprietorship vs Pte Ltd in Singapore is mainly a question of profit. On the assumptions below, a sole proprietor pays less income tax up to roughly $100,000 of annual profit. Above that, a company paying you a director's fee plus dividends pays less, and the saving covers a company's extra running costs from roughly $130,000 a year.

Those figures assume the company is past its first three Years of Assessment (YAs). The start-up tax exemption lowers a new company's tax in those years, but three years is too short to base the decision on.

This guide is for freelancers and sole proprietors deciding whether to incorporate. Amounts are in Singapore dollars, based on IRAS, ACRA and CPF Board rules as at November 2026.

Key takeaways

• Sole proprietor: profit is taxed as your income at 0% to 24% after reliefs, withdrawn or not, and Citizens and PRs must pay MediSave once net trade income exceeds $6,000.
• Company: a 17% headline rate, but about 8.3% effective on $200,000 of chargeable income after the partial tax exemption, and dividends are tax-free.
• Break-even: about $100,000 of profit on tax alone if the company pays you a sensible director's fee (about $170,000 if everything goes out as dividends), and about $130,000 once a company's extra running costs are counted.
• GST: the same $1 million threshold, but all of a sole proprietor's businesses count together.
• Converting: incorporate, transfer the business, cease the sole proprietorship on Bizfile (free) and report its final months in your next Form B.

How Is a Sole Proprietorship Taxed in Singapore?

A sole proprietorship is not a separate legal entity, so its profit is your income. You report it in Form B, the return for self-employed individuals, by 18 April, and IRAS taxes it with any other income at resident rates from 0% to 24%, whether you withdraw the profit or leave it in the business.

Your own salary, drawings and CPF contributions are not business expenses. Instead, personal reliefs reduce the income that is taxed:

• Earned Income Relief: $1,000 below age 55, and more from 55.
• Compulsory MediSave: full relief for contributions paid in the previous year.
• Other reliefs, such as parent, child or SRS relief, with all reliefs together capped at $80,000 a year.

Reporting is light. With revenue of $200,000 or less, Form B needs two lines, revenue and adjusted profit; above that, four. A certified statement of accounts is needed only from $500,000 of revenue, but you must keep full records for at least five years. See Form B vs Form B1 if you are unsure which return is yours, and our guide to deductible business expenses for what you can claim.

How Is a Pte Ltd Company Taxed?

A private limited company is a separate taxpayer. It pays a flat 17% on chargeable income after one of two exemptions:

• Start-up tax exemption (SUTE), first three YAs: 75% of the first $100,000 and 50% of the next $100,000 are exempt. IRAS confirms that a company converted from a sole proprietorship can claim it if it meets the conditions; see our start-up tax exemption guide.
• Partial tax exemption, from the fourth YA, or from the start if SUTE is not available: 75% of the first $10,000 and 50% of the next $190,000 are exempt.

A 50% CIT Rebate roughly halved small companies' YA 2026 tax (total benefits capped at $40,000), but none has been announced for YA 2027, so the comparisons below leave it out.

After tax, dividends reach you tax-free under Singapore's one-tier system. A director's fee voted by shareholders is deductible for the company and taxed at your personal rates, with no CPF. A salary under a contract of service is treated the same way, but attracts CPF if you are a Singapore Citizen or PR. Our guides to director's salary vs dividends and corporate tax filing cover the mix and the company's returns.

Sole Proprietor vs Company Tax Rate on Each Extra Dollar

Comparing 17% with your top personal rate misleads. What matters is the rate on your next dollar of chargeable income:

Your personal rate overtakes a company's 8.5% at $80,000 of chargeable income, where it jumps from 7% to 11.5%. That crossover explains the break-even, and why a director's fee of about $80,000 is often the efficient amount.

Sole Proprietorship vs Pte Ltd Singapore: Tax at 7 Profit Levels

Total income tax on the same annual profit under three set-ups, including your personal tax on any director's fee. The lowest figure in each row is in bold.

In the company's first three YAs the company figures fall further: at $100,000 of profit, to $4,250 with all dividends or $3,058 with a $41,000 fee.

Assumptions Behind the Table

• You are a Singapore Citizen, tax resident and under 35, with no other income.
• Profit is the business's adjusted profit before paying yourself anything, the same in both structures. Running costs are compared separately below, as a flat amount, ignoring the small tax saving the fees themselves give.
• Sole proprietor: only Earned Income Relief and compulsory MediSave relief at CPF Board's 2026 rates, with steady profits so each year's relief equals the contribution. No personal tax rebate, as none has been announced for YA 2026.
• Company: past its first three YAs, no CIT Rebate, and after-tax profit paid out as dividends.
• Fee route: a director's fee approved by shareholders, set where your personal rate on the next dollar would overtake the company's, with the rest paid as dividends.
• Figures are rounded to the nearest dollar.

How the $150,000 Row Is Worked Out

• Sole proprietor: $150,000 less $1,000 Earned Income Relief and $7,680 MediSave relief leaves $141,320. Tax is $7,950 on the first $120,000 plus 15% of $21,320 ($3,198): $11,148.
• Company, all dividends: the exemption is $77,500 (75% of $10,000 plus 50% of $140,000), leaving $72,500 taxed at 17%: $12,325.
• Company with an $81,000 fee: chargeable income falls to $69,000. After a $37,000 exemption, $32,000 at 17% is $5,440. Your fee less $1,000 relief is $80,000, taxed at $3,350. Total: $8,790, or $2,358 less than the sole proprietor pays.

At What Profit Should You Incorporate in Singapore?

Repeating the calculation at every profit level gives these break-even points, the annual profit above which the company option pays less (same assumptions, owner under 35):

Three conclusions follow:

1. Decide on the last row. The start-up YAs are a bonus, not a reason. With steady profit of about $130,000 or more, incorporating usually pays for itself.
2. How you pay yourself matters as much as the structure. Taking everything as dividends wastes your personal 0% to 7% bands and pushes the break-even to about $170,000.
3. Your own position moves the line. From age 35, higher MediSave rates, and from 55 a larger Earned Income Relief, give a sole proprietor more relief, raising the fee-route break-even on tax alone by roughly $4,000 at 35 to $16,000 at 60 and over. Other reliefs, such as parent, child or SRS relief, also favour the sole proprietor because they come off income taxed at higher rates.

The $1,000 is an illustrative figure for the extra yearly fees a company brings, explained in the next section. If you do your own bookkeeping today, the gap may be nearer $2,000 and the break-even nearer $145,000. Our corporate tax calculator works out the company side on your own figures.

What Does Each Structure Cost to Run?

Those extra professional fees, plus $30 more a year in ACRA fees, are the $1,000 used in the break-even table: an illustrative round figure, not a quote. Fees depend on transaction volume and the state of the records, so get quotes for both structures; our annual packages and accounting services list ours.

A company you own alone is usually an exempt private company, a category that allows up to 20 individual shareholders and no corporate shareholder. If solvent, it prepares financial statements but need not file them with ACRA, and it will usually qualify for the small-company audit exemption.

CPF and MediSave for the Self-Employed vs Company Owners

As a Singapore Citizen or PR sole proprietor, you pay MediSave once net trade income exceeds $6,000. CPF Board's 2026 rates rise from 4% to 5.25% at the low end to 8% to 10.5% above $18,000, depending on age, capped at $7,680 to $10,080 a year. Payment is due 30 days after CPF Board's notice, and ACRA cannot renew your registration while MediSave is outstanding unless you are on an instalment plan.

A company owner's CPF depends on how they are paid:

So the company owner in our table keeps more cash but builds no CPF at all, while the sole proprietor on $100,000 of profit puts $7,680 a year into MediSave. If CPF savings matter to you, taking part of your pay as salary restores them.

Sole proprietors can also top up voluntarily. Compulsory MediSave always gets full relief; voluntary top-ups get relief only while total MediSave and voluntary CPF stays within the lowest of 37% of assessed net trade income, $37,740 and the amount contributed.

The Non-Tax Differences That Matter

Liability and Legal Status

ACRA is plain about it: a sole proprietorship is not a separate legal entity and its owner has unlimited liability, so your personal assets are exposed to business debts. A company is a separate legal entity whose shareholders have limited liability. In practice, banks and landlords often ask small-company directors for personal guarantees, and directors take on duties under the Companies Act 1967, so the protection is narrower than many owners expect. A limited liability partnership also gives limited liability and is taxed at its partners' personal rates, but ACRA requires two or more partners, so it is not an option for a one-person business.

Credibility, Ownership and Funding

Some corporate clients prefer to contract with a Pte Ltd. A company can bring in a co-founder or investor by issuing shares, which a one-owner sole proprietorship cannot. A company also continues until it is wound up or struck off, while a sole proprietorship lasts only as long as you are alive and choose to run it.

Grants and Government Support

Most support depends on hiring local staff, not on legal form. The YA 2026 CIT Rebate Cash Grant of $2,000 needed CPF contributions for a local employee who was not a shareholder-director; wages paid to business owners do not count for the Senior Employment Credit; and owners do not count towards the three local employees an Enterprise Innovation Scheme cash payout needs.

One quirk: the SME Cash Grant 2026, paid from November, gives a Citizen or PR sole proprietor with no local staff a flat $500 if their YA 2025 net trade income was $100,000 or less. Companies with no local qualifying employees get nothing, though a shareholder-director whose CPF was paid on time counts as one.

GST: Same Threshold, Different Counting

Both structures must register for GST once taxable turnover exceeds $1 million in a calendar year, or is expected to in the next 12 months. But IRAS adds together all your sole proprietorships and other trade or professional income under your name, while a company counts only its own turnover. A company that takes over your business must include that business's turnover, so incorporating does not reset the count.

How to Convert a Sole Proprietorship to a Private Limited Company

There is no conversion form. You set up a company, move the business into it and close the sole proprietorship:

1. Pick a transfer date and year end. The start-up exemption's three YAs count from incorporation, not from when your business began, so choose the company's year end with them in mind.
2. Incorporate on Bizfile. ACRA's fees are $315. You need a director ordinarily resident in Singapore, a company secretary within six months, and Corppass for IRAS's digital services.
3. Open a company bank account and transfer the business. Document the transfer of equipment, stock, debtors, contracts, staff and licences, and invoice in the company's name from the transfer date.
4. Elect under section 24 for equipment. If you claimed capital allowances, you and the company can sign a section 24 Notice of Election under the Income Tax Act 1947, so the equipment moves at its tax written-down value with no balancing charge in your final Form B. The company then claims the remaining allowances.
5. Deal with GST if registered. A liable company registers within 30 days of the transfer, effective from that date, and the sole proprietorship cancels within 30 days. No output tax is due on its assets if the whole business passes as a going concern to the GST-registered company. A voluntary registration also brings the GST InvoiceNow requirement.
6. Cease the sole proprietorship on Bizfile. The cessation e-service is free and immediate, accepts a past, current or future date and cannot be reversed. Match the date to the transfer, and renew first if the registration has expired.
7. File your final Form B. Income from 1 January to the cessation date goes in your next return: cease on 31 March 2027 and it goes in the YA 2028 Form B, due by 18 April 2028, with MediSave assessed on it.

Timing Tips

• Switch once profit has been above the break-even for a year or two, not after one exceptional year.
• 1 January is the tidiest date: your final Form B then covers a full calendar year. A mid-year switch splits that year's profit between your last Form B and the company's first basis period.
• Avoid a first financial year that ends before the company starts trading, because a YA with no income still uses up a start-up exemption YA.
• Cease the sole proprietorship before its registration expires, so you do not pay for an unused renewal.

Common Mistakes When Choosing Between Them

• Treating company money as yours. Withdrawals that are not fees, salary, dividends or expense claims become loans to a director, which section 162 of the Companies Act 1967 prohibits unless the company is an exempt private company, subject to limited exceptions.
• Splitting one business across several companies. IRAS treats moving a profitable going concern's income into shell companies to multiply the start-up exemption as abuse of the scheme.
• Forgetting the second person. A one-person company still needs a company secretary who is not the sole director.
• Leaving the sole proprietorship registered. It keeps needing renewals and blurs which entity earned what.

When Should You Get Professional Advice?

You probably need neither advice nor a company if your profit is under about $80,000, no client insists on a Pte Ltd and unlimited liability does not worry you. Stay a sole proprietor and file Form B yourself.

Get your numbers checked if profit has been above $100,000 for a couple of years, or if you are GST-registered, employ staff or have claimed capital allowances. The section 24 election, the GST steps and their order are the parts most worth getting right.

Tax Filing SG is run by ex-Big 4 Singapore Chartered Accountants (ISCA members). We can compare both structures on your figures, incorporate the company and handle its accounts, tax and secretarial work. If you stay a sole proprietor, our personal tax filing service can prepare your Form B.

Frequently Asked Questions

Is a sole proprietorship taxed less than a company in Singapore?

At lower profits, yes. Personal rates stay at 7% or below until $80,000 of chargeable income, while a company pays 8.5% on each dollar of chargeable income between $10,000 and $200,000 under the partial tax exemption. On our assumptions, a sole proprietor pays less tax up to roughly $100,000 of annual profit; above that, a company paying its owner a sensible director's fee usually pays less.

Can I convert my sole proprietorship to a Pte Ltd?

Yes, though not by amending the registration. You incorporate a new company, transfer the business to it, deal with GST if registered, then cease the sole proprietorship on Bizfile, which is free and immediate. Income up to the cessation date goes in your next Form B. IRAS confirms the new company can claim the start-up tax exemption for its first three YAs if it qualifies.

Do sole proprietors pay CPF?

Only MediSave is compulsory, and only if you are a Singapore Citizen or PR with net trade income above $6,000 a year. CPF Board's 2026 rates range from 4% to 10.5% depending on your age and income, capped at $7,680 to $10,080 a year, with payment due 30 days after the notice. Compulsory MediSave gets full tax relief, and ACRA cannot renew your registration while it is outstanding unless you are on an instalment plan.

Does a sole proprietorship need to file accounts with ACRA?

No. A sole proprietorship files no financial statements or annual return with ACRA; it just renews its registration every one or three years. Its duties are to IRAS: keep proper records for at least five years, report revenue and adjusted profit in Form B, and submit a certified statement of accounts only if revenue is $500,000 or more.

Which is better for freelancers in Singapore?

For most freelancers, a sole proprietorship, or simply trading under your own full name, is cheaper and simpler. A company makes sense when profit is steadily above about $130,000 a year, clients insist on a Pte Ltd, you want business debts kept apart from your personal assets, or you plan to hire staff or bring in an investor. Below that, the extra compliance usually costs more than it saves.

Do I need to register a business to freelance in Singapore?

Not if you trade only under your full name as it appears on your NRIC. ACRA requires anyone regularly carrying on an activity for profit to register, but exempts trading under your own full name. Adding a brand means you must register, and failing to do so can lead to a fine of up to $10,000, up to two years' imprisonment, or both. Either way, you must file Form B once your net profit exceeds $6,000, or whenever IRAS asks you to file.
