HomeCorporate Tax Filing
ECI, Form C-S and Form C for Singapore companies, prepared from your own accounts, with the Start-up Tax Exemption claimed while the years it applies to are still open.
Two deadlines drive the tax year, and one relief drives the first three. Missing the relief costs more than missing a date, because there is no route back later.
Estimated chargeable income is filed within three months of your financial year end, unless the company qualifies for the waiver. We check which applies to your company instead of filing out of habit.
The return is due 30 November. Which form applies turns on the company's size and circumstances, and the wrong choice means either more disclosure than you owe or a rejection you fix under time pressure.
Relief runs at 75% on the first S$100,000 of chargeable income and 50% on the next S$100,000, for the first three years of assessment. Property development and investment holding companies are excluded from it.
Start at the accounting profit, then adjust. Disallowed expenses, capital allowances and non-taxable income are worked through line by line, which is how the 17% rate ends up applied to a smaller figure than your profit.
Supporting schedules stay with the return rather than being assembled after a query lands. When IRAS asks about a deduction two years later, the answer sits in the file instead of in somebody's memory of a supplier.
Letters and notices reach companies through the registered office and through Corppass. Both get watched, replies are drafted, and anything needing a decision from you arrives with a recommendation attached to it.
Two filings a year, on fixed dates, prepared from accounts that are already current. The work spreads through the year rather than landing in November.
Accounts for the financial year are finalised first, because the computation reads from them. Where the bookkeeping has gaps, they get fixed now rather than estimated into a return that carries your signature and your company's name.
After year endEstimated chargeable income goes to IRAS within three months of year end, unless the waiver applies. It is an estimate and still worth getting close to right, because it drives how the tax is paid across the year.
Within three months of year endThe tax computation, capital allowance schedules and the Start-up Tax Exemption claim are drawn up and sent to you to review. Anything in a grey area is flagged with the reasoning, so the decision is yours and recorded.
Before 30 NovemberForm C-S or Form C is filed by 30 November with the computation attached. You get the assessment when it arrives, along with what is payable and when, and later queries are handled from the same file.
By 30 NovemberIt comes as part of the Comply package. ECI and Form C-S sit inside it, alongside a named company secretary, registered office and mail scanning, AGM documents and the annual return, statutory registers, financial statements and XBRL.
Companies filing a full Form C, or dealing with overseas income, group relief or unusual claims, are quoted on top of the package. That number reaches you before the work starts, which is the only time a number is worth anything.
Quoted for your company
Agreed in writing before we start
Ask about ComplyThe Comply package is quoted for your company before we start. Form C filings and unusual claims are quoted on top of it.
Form C-S or Form C is due 30 November. Before that, estimated chargeable income is filed within three months of your financial year end, unless your company qualifies for the waiver. They are two separate filings on two separate dates, and meeting one does nothing for the other.
Relief of 75% on the first S$100,000 of chargeable income and 50% on the next S$100,000, for the first three years of assessment. Property development and investment holding companies are excluded. Set against the 17% corporate tax rate, that is the difference between a manageable first tax bill and a painful one.
The relief attaches to the first three years of assessment. Once those years have been assessed, a claim in year four has nowhere to go, because the window it belongs to has closed. This is the most expensive thing a founder loses by not asking, and it goes quietly.
Yes. A dormant or loss-making company still has a filing obligation, and the return is what puts losses on record for carrying forward against later profits. Skipping it because no tax is payable leaves you with a compliance problem and no losses to use when you finally need them.
The Comply package covers financial statements, XBRL where required, ECI and Form C-S. Monthly bookkeeping is not part of it. Tax work still needs a ledger to read from, so if nobody is keeping your records through the year, that is a separate conversation about the Complete package.
If your company is inside its first three years of assessment and nobody has mentioned the Start-up Tax Exemption to you, send the returns filed so far and we will look at them.
