CORPORATE TAX GUIDE · UPDATED OCTOBER 2026
Year-end tax planning: at 8.5 cents in the dollar, buying things to save tax is a bad trade
Every December an owner asks whether to buy the van, pay the bonus or vote a fee before the year closes, and the articles answer at 17%. Almost no Singapore SME pays 17%. After the partial exemption, profit between S$10,000 and S$200,000 is taxed at 8.5%, and a company in its start-up years pays 4.25% on its first S$100,000. At those rates, the planning that pays is about dates and documents, not spending. This guide works through a December for a company with a 31 December year-end, taxed in Year of Assessment 2027.
ONE DECEMBER, FOUR DECISIONS
S$18,257 becomes S$13,591, and none of it is spending.
Take the distributor from the management accounts, cash-flow, CFO and budget guides: about S$2 million of sales, eight staff, a bank loan, a December year-end. The budget guide forecast 2026’s profit at S$209,894and its tax at S$18,257: 17% after the partial exemption, no rebate. S$9,894 of that profit sits above the S$200,000 exemption ceiling, so the first S$9,894 of any deduction is worth 17 cents in the dollar and everything after it 8.5. Here is what the owner does in December, in order, and what each is worth.
| Decision | Deduction | Tax saved | Where the number comes from |
|---|---|---|---|
| YA 2027 tax before planning | — | 18,257 | S$209,894 of chargeable income: 75% of the first S$10,000 and 50% of the next S$190,000 exempt, 17% on the rest. |
| The year-end bonus, decided and announced in December | −14,000 | −2,031 | S$12,000 across seven employees, plus about S$2,000 of employer CPF, on top of the contractual 13th month. The amounts are fixed by person, the staff are told in writing before Christmas, the accrual is booked, and it is paid with February's payroll. Decided in January instead, the same bonus is a YA 2028 deduction. |
| The dead invoice, written off by name | −6,500 | −553 | A customer 150 days overdue, uncontactable since September, with a chase trail to prove it. Written off invoice by invoice before the year closes, it is deductible. Carried as an asset and provided against in round numbers, it is not. The GST on it comes back separately, once the invoice is twelve months old. |
| Training on funded courses, claimed under the Enterprise Innovation Scheme | −12,000 | −1,020 | S$4,000 of forklift, workplace-safety and Xero courses the warehouse and admin staff were doing anyway. Because the courses are SWDA-funded and on the Skills Framework, the scheme allows 400%: S$16,000 of deduction for S$4,000 of spend. The extra S$12,000 is tax the company would never otherwise have saved. |
| The annual donation, made in December instead of January | −12,500 | −1,062 | The owner gives S$5,000 to a children's charity every January. Given in December it is a 250% deduction for YA 2027; in January, the same deduction for YA 2028. The rate is identical either way: Budget 2026 extended it to the end of 2029. The gift saves S$1,063 of tax and costs S$3,937. |
| YA 2027 tax after planning | −45,000 | 13,591 | S$164,894 of chargeable income. S$4,666 less tax, paid as ten smaller GIRO instalments from February. |
Read the saving honestly. S$1,020 of it is tax the company would never otherwise have paid: the 300% uplift on training that was happening anyway. The other S$3,646 is tax the company would have saved in YA 2028, arriving a year earlier because a bonus was announced in December rather than January, an invoice was written off rather than carried, and a donation moved six weeks. Both are worth having. Only the first is worth changing a decision for; the second is worth a letter, a journal and a date.
Why the bonus saves S$2,031 and not 8.5% of S$14,000.
The exemption stops at S$200,000 of chargeable income. The distributor is S$9,894 above it, so the first S$9,894 of the bonus is deducted from profit taxed at 17% and the remaining S$4,106 from profit taxed at 8.5%. Every deduction after that is worth 8.5 cents. A company that does not know whether it is above or below S$200,000 cannot value any decision on this page, which is why the first step is closing November.
THE S$65,000 QUESTION
The purchase that saves S$4,958 and is worth about S$273.
The budget has the warehouse lease renewing on 1 July 2027, and the owner has planned S$40,000 of racking (sixteen bays at S$2,500) and a S$25,000 refit of the warehouse office for then. A supplier offers a December discount and the question arrives: do it now and claim it against 2026?
What the tax computation would show
Each bay costs under S$5,000, so the racking is a low-value asset: S$30,000 written off in YA 2027 under the one-year rule and the remaining S$10,000 over three years. The refit is renovation, and the owner can elect to deduct all S$25,000 in one year. Together, S$58,333 of deductions, all at 8.5%: the YA 2027 bill falls from S$13,591 to S$8,633. S$4,958 saved.
What it is actually worth
Bought in July as planned, the same S$58,333 is deducted in YA 2028 and saves the same S$4,958a year later. December buys one year of that tax, which at the loan’s 5.5% is about S$273. The discount is a reason to buy early. The tax is not; it is the same tax, dated differently.
And the cash view settles it.
The cash budget has January as the tightest month of 2027, closing at S$58,424, because December’s CPF, the CPF on the 13th month and the fourth-quarter GST all leave in the same month. S$65,000 paid in December takes that to minus S$6,576, S$36,576 below the S$30,000 floor the cash-flow guide set, and the S$5,850 of GST on the purchase only comes back after the January return. The answer is July, as budgeted, and the renovation cap is no reason to hurry: the first fixed three-year period ends at YA 2027, but a new S$300,000 cap starts in YA 2028.
HOW TO DO IT
Six steps, in this order.
Close October and November before you plan anything
Planning needs a number to plan against: this year's chargeable income, estimated from ten closed months and a forecast for two. A company whose September bank reconciliation is still open does not know whether it is above or below S$200,000, and that one fact decides whether a deduction is worth 17 cents or 8.5.
Find the rate you actually pay
Under the partial exemption the first S$10,000 of chargeable income is taxed at 4.25%, the next S$190,000 at 8.5%, and only the excess over S$200,000 at the full 17%. A company in its first three years pays 4.25% on its first S$100,000. Write your marginal rate at the top of the page. Every idea below is worth that many cents in the dollar, no more.
Put a date and a document on the decisions already made
The bonus you intend to pay, the invoice you know is dead, the donation you make every year, the fee you will vote at the AGM: none of these needs a new decision. They need the paperwork IRAS looks for, dated before 31 December. A bonus letter by person. A write-off by invoice, with the chase trail. A receipt from the charity. An accrual in the accounts for the fee, and a line on the AGM agenda.
Claim what is already in the books
Computers and anything costing S$5,000 or less bought this year are written off in full. Fit-out that was capitalised can take the renovation deduction, one year or three. Course fees on funded courses qualify for 400% under the Enterprise Innovation Scheme, and from YA 2027 so does qualifying AI spend. Medical costs are deductible to 1% of remuneration, 2% with a portable scheme. None of this costs anything; it only has to be found.
Run the purchase test before you buy anything
Would you buy it in January anyway? Then the tax saving is not the deduction. It is a year's interest on the deduction, because the write-off arrives in YA 2028 instead of YA 2027. Would you not buy it otherwise? Then you are spending a dollar to save 8.5 cents. Check the 13-week forecast before pulling any cash forward: December's purchases leave in the month the fourth-quarter GST and the 13th month's CPF leave too.
Decide the ECI plan now, not in March
File the Estimated Chargeable Income within a month of the year-end and the tax is paid in ten instalments from February; within two months, eight; within three, six. The planning above shows up as smaller instalments, not a cheque. A company that can file in January is a company whose December closed on time, which is what step one was for.
THE LINES
Twelve rules, and what each asks of you before 31 December.
Each of these is a deduction with a condition attached, and in most cases the condition is a date or a document rather than a payment. Rates and schemes as published by IRAS on 4 October 2026, including the changes from Budget 2026.
| Line | The rule | Before 31 December |
|---|---|---|
| Capital allowances (Section 19A) | Computers, prescribed automation equipment and assets costing S$5,000 or less are written off in one year, the low-value assets up to S$30,000 of claims a YA and the rest over three years or the asset's working life. Private cars get nothing. On hire purchase, the allowance follows the deposit and principal actually paid. | The asset has to be bought and in use by 31 December: ordered in December and delivered in January is a 2027 asset. Claims can be deferred to a later YA, which matters if you are in your start-up years. |
| Renovation and refurbishment (Section 14N) | Fit-out that is not plant — flooring, lighting, partitions, fixed cabinets, and since YA 2025 the designer's fee for non-structural work — is deductible over three years, or in one by an election that cannot be reversed. The cap is S$300,000 for each fixed three-year period; the first runs YA 2025 to YA 2027. | YA 2027 is the last year of the first cap period, and the next starts fresh in YA 2028. For almost every SME the cap is not the constraint. The one-year election is the decision, and it is made on the return, not in December. |
| Enterprise Innovation Scheme: training | 400% deduction on the first S$400,000 a year of course fees for SWDA-funded courses aligned with the Skills Framework, including certification and assessment fees. YA 2024 to YA 2028. | Book and pay for the course this year, and check the course is on the funded list before you rely on it. The scheme turns S$4,000 of training into S$16,000 of deduction. |
| Enterprise Innovation Scheme: AI | New in Budget 2026: 400% deduction on up to S$50,000 a year spent subscribing to or licensing an AI system or a qualifying AI business service, for YA 2027 and YA 2028 only. Hardware and anything grant-funded are excluded, and the cash payout option does not apply. | If a qualifying tool was going in anyway, S$10,000 of subscription is S$40,000 of deduction: S$3,400 of tax at 8.5%, a third of the cost back. Keep the invoice and the subscription terms; IRAS's e-Tax guide defines what counts. |
| Enterprise Innovation Scheme: cash payout | Instead of the deduction, convert up to S$100,000 of qualifying spend a year into cash at 20%: at most S$20,000, not taxable. Needs three full-time local employees for at least six months of the year and a return filed on time. | Only better than the deduction when you cannot use the deduction: a loss year, or a start-up year taxed at 4.25%. At 8.5%, S$4,000 of training is worth S$1,360 as a deduction and S$800 as cash. |
| Donations | 250% of a cash donation to an Institution of a Public Character or Community Chest, deducted in the YA after the year you give. Budget 2026 extended the rate to 31 December 2029. Unused donations carry forward for five YAs. | December counts for YA 2027, January for YA 2028, at the same rate. A S$5,000 gift saves S$1,063 at 8.5%. It costs S$3,937; it is a gift, not a strategy. |
| Bonuses | Deductible when the liability to pay arises. IRAS accepts a non-contractual bonus in the year it is accrued if the amount is properly ascertained and it is paid within a year of that accounting year. A round-number provision is not deductible. | Decide the amounts by person, tell the staff in writing, book the accrual. Paying in February does not move the deduction out of 2026. Deciding in February does. |
| Director's fees | Fees approved in arrears are deductible in the year accrued if they are tabled and voted at the AGM that approves that year's accounts, with payment following. The director is taxed on the date of the vote. | A fee accrued for 2026 and voted at the 2027 AGM is a YA 2027 deduction for the company and 2027 income for the director: a year apart. Whether it saves anything at all depends on the slice above S$200,000, below. |
| Medical expenses | Deductible up to 1% of total staff remuneration, CPF included; 2% if the company runs a portable medical scheme or makes ad-hoc MediSave contributions under CPF Board's Additional MediSave Contribution Scheme, up to S$2,730 per employee a year. | Know the 1% before December's claims land. For the distributor it is S$5,249; the 2% is S$10,497. |
| Bad debts | A trade debt written off, or specifically provided against by customer, is deductible. A general percentage is not. The GST on it comes back as bad debt relief once twelve months have passed since the supply, the debt is written off and you have made reasonable efforts to collect. | Write off dead invoices by name before the year closes. Keep the chase emails; IRAS asks for them. |
| Private cars, prepayments, fines | No deduction for S-plated car costs, however the car is used, and no capital allowance on the car. Next year's insurance paid in December is next year's expense. Fines, private spending and capital costs are added back. | None of these move the YA 2027 bill. Do not spend in December hoping they will. |
| Loss carry-back | Current-year trade losses and capital allowances up to S$100,000 can be carried back one YA, against YA 2026's income, for a refund of the tax paid on it. It has to be claimed, on Form C rather than Form C-S, and the shareholding and same-business tests apply. | If 2026 is a loss after a profitable 2025, this is worth up to S$17,000 and is the opposite of deferring. Decide before the ECI, so the instalment plan reflects it. |
S$1,000 of thanks, two ways.
Paid as a cash bonus, S$1,000 costs the company S$1,170 with employer CPF, all of it deductible, and reaches the employee as S$800 after their own CPF, taxed as income. Paid into the employee’s MediSave under CPF Board’s Additional MediSave Contribution Scheme, it costs the company S$1,000, is deductible within the 2% medical cap the contribution itself unlocks, and arrives in full, with no CPF and, within the scheme’s S$2,730 a year, no tax for the employee. It is not spendable money: it pays MediShield Life premiums and hospital bills. For some teams that is the point, and for others it is a reason to pay cash. The tax saving is not what decides it; the staff are.
THE FEE QUESTION
A director’s fee pays only on the slice above S$200,000.
The most repeated piece of December advice is to vote yourself a fee before the year ends. A fee is deductible to the company and taxable to you, so it saves tax only where the company’s marginal rate is higher than yours. The distributor’s owner draws S$8,000 a month and a 13th month, and after CPF relief sits in the 11.5% personal band. The company pays 17% on the S$9,894 above the ceiling and 8.5% on everything below it.
A fee of S$9,894
Saves the company S$1,682 at 17% and costs the owner S$1,138 at 11.5%: S$544 ahead, with no CPF because fees voted at a general meeting carry none. That is the whole prize, and in the distributor’s December the bonus has already used the slice.
A fee of S$30,000
Once the company is below S$200,000, the fee saves 8.5% and costs 11.5%: S$2,550 saved, S$3,450 paid, S$900 worse off than leaving the profit in the company and taking the June dividend the budget already planned. Dividends are not taxed in your hands.
The timing rule is the useful part. A fee accrued in the 2026 accounts and tabled at the 2027 AGM that approves them is a YA 2027 deduction for the company and 2027 income for the director, a year apart. That is a deferral, not a saving, and it only exists if the fee reaches the AGM agenda. An owner whose personal rate is 7%, or who has no other income, gets a different answer from the same arithmetic.
TWO COMPANIES THAT SHOULD DO THE OPPOSITE
In your start-up years, or in a loss year, deferring beats accelerating.
A company in its first three YAs
Under the start-up exemption a deduction against the first S$100,000 of chargeable income is worth 4.25 cents. In year four the same deduction is worth 8.5, or 17. So a start-up with a profit should not be pulling anything forward: it should take the three-year write-off rather than the one-year, it should not make the irrevocable one-year renovation election, and it can defer capital allowance claims outright. IRAS names the start-up exemption as one of the two reasons companies defer. The exception is cash: a company that needs the money now takes the deduction now.
A company whose 2026 is a loss
Deductions in a loss year save nothing this year; they join the losses carried forward, subject to the shareholding test. Two things change that. Up to S$100,000 of the current year’s losses and capital allowances can be carried back against YA 2026’s income for a refund of the tax paid on it, if you claim it. And qualifying training spend can be converted into a cash payout at 20% instead of a deduction you cannot use, if the company had three full-time local employees for six months of the year. A company raising money should also check the shareholding test before the round closes: a change of more than half the shareholders can forfeit the losses.
WHAT GOES WRONG
Four ways December planning costs more than it saves.
It spends money to move a date
Almost every 'buy it before year-end' saving is a timing difference: the deduction arrives in YA 2027 instead of YA 2028. The value of that is a year's interest on the tax, not the tax. For the distributor's S$65,000 of racking and refit it is about S$270, against S$65,000 leaving the bank in the tightest month of the year.
It plans at 17% when the company pays 8.5%
The headline rate is what the planning articles quote and almost no SME pays. Below S$200,000 of chargeable income the marginal rate is 8.5%; in the start-up years it is 4.25% on the first S$100,000. A deduction that looks worth S$1,700 is worth S$850, or S$425, and a decision that was marginal at 17% is wrong at 8.5%.
It skips the paperwork IRAS actually looks for
A bonus with no letter and no amounts by person is a provision, and provisions are added back. A director's fee that never reaches the AGM agenda is not deductible in the year it was accrued. A bad debt provided for at 5% of the ledger is not a write-off. The decisions were sound. The deductions fail on the documents.
It happens in March
By March every date has passed. What is left are the elections on the return: one year or three for the renovation deduction, whether to defer capital allowances, whether to carry a loss back. Useful, but they move tax between years. The decisions that change the bill are made in a December that was planned, which means a November that was closed.
Common questions.
When does year-end tax planning have to be done for a Singapore company?
Before the financial year ends: 31 December 2026 for a December year-end, which is taxed in Year of Assessment 2027. After that date the only levers left are the elections made on the return itself, such as writing off renovation in one year rather than three, deferring a capital allowance claim or carrying a loss back. The ECI then falls due within three months of the year-end, and the return, Form C-S or Form C, by 30 November 2027. A company with another year-end works back from its own date in the same way.
How much corporate tax does a Singapore SME actually pay?
Less than 17%. Under the partial tax exemption, 75% of the first S$10,000 of chargeable income and 50% of the next S$190,000 are exempt, so the marginal rate is 4.25%, then 8.5%, and only 17% above S$200,000. A company with S$100,000 of chargeable income pays S$8,075, an effective rate of about 8.1%. A qualifying new company in its first three YAs pays 4.25% on the first S$100,000 and 8.5% on the next S$100,000. The distributor in this guide pays S$18,257 on S$209,894 before planning, an effective rate of 8.7%.
Is there a corporate income tax rebate for YA 2027?
Not as at October 2026. The YA 2026 rebate is 50% of tax payable, with a S$2,000 cash grant for companies that employed a local employee in 2025 and a combined cap of S$40,000. Rebates are announced one Budget at a time, and Budget 2027 will be delivered in February 2027, after a December year-end has closed. Plan at the full rates after the exemption; if a rebate comes, it reduces the bill rather than the planning.
Can a bonus decided in December but paid in February be deducted in the 2026 accounts?
Yes, if it is a real liability by 31 December and not a provision. IRAS's practice is to allow a non-contractual bonus in the year it is accrued where the amount is properly ascertained, it is accrued in the accounts under the normal accounting standards, and it is paid within a year of that accounting year. In practice: decide the amount for each person, tell them in writing before the year ends and book the accrual. A single line for 'bonus provision' with the split still to be decided is added back. The same logic applies to director's fees, which also need to be tabled at the AGM that approves the year's accounts.
Should I pay myself a director's fee before 31 December to reduce company tax?
Only on the slice of profit taxed at 17%. A fee is deductible to the company and taxed as your income, so it saves tax only where the company's marginal rate is higher than yours. Below S$200,000 of chargeable income the company pays 8.5%, and most owner-directors are already in the 11.5% personal band or above, so a fee costs 3 cents in the dollar more than leaving the profit in the company and taking a dividend. Above S$200,000 the company pays 17% and a fee taxed at 11.5% saves 5.5 cents. Fees voted at a general meeting carry no CPF. A fee accrued for 2026 and voted at the 2027 AGM is deductible in YA 2027 and becomes your income in 2027.
Is buying equipment before the year-end a good way to reduce tax?
Usually not, unless you were buying it in the next few months anyway, and then the saving is smaller than it looks. Computers, prescribed automation equipment and assets costing S$5,000 or less are written off in one year, the low-value items up to S$30,000 of claims per YA; everything else over three years or the asset's working life. The asset has to be bought and in use by 31 December. Pulling a planned purchase into December brings the write-off forward by a year, which is worth a year's interest on the tax, while the cash leaves in the month that also carries the fourth-quarter GST and December's CPF. Buying something you did not need spends a dollar to save 8.5 cents. And a private car saves nothing at all: S-plated car costs are not deductible and carry no capital allowance.
What is the Enterprise Innovation Scheme and can a small company use it?
A 400% tax deduction on the first S$400,000 a year of qualifying spend in each of five activities, available from YA 2024 to YA 2028. For most SMEs the usable activity is training: course fees on SWDA-funded courses aligned with the Skills Framework, including certification and assessment fees, so S$4,000 of courses is S$16,000 of deduction. Budget 2026 added a category for adopting AI, 400% on up to S$50,000 a year for YA 2027 and YA 2028, covering subscriptions to or licences of AI systems and AI business services but not hardware. A company that cannot use the deduction, because it is in a loss or its start-up years, can instead convert up to S$100,000 of qualifying spend into a non-taxable cash payout at 20%, if it has three full-time local employees for at least six months of the year and files on time. The AI category is deduction only.
Are donations tax deductible for a Singapore company, and when?
Cash donations to an Institution of a Public Character or the Community Chest attract a 250% deduction, claimed in the YA after the year of the gift: a December 2026 donation reduces YA 2027 tax, a January 2027 donation reduces YA 2028's. Budget 2026 extended the 250% rate to 31 December 2029, so there is no rush to give before the year-end on the rate's account. Donations that cannot be used in the year carry forward for up to five YAs. At 8.5%, a S$5,000 donation saves S$1,063 and costs S$3,937: worth knowing, not a reason to give.
