Filing Form C is the final step. Before filing your company’s income tax return, the tax agent checks the accounts and works out the figures needed for the return. This is where the best tax filing firm singapore can be useful, before the return is filed. When done well, this review affects both how much tax you pay and how smoothly the return goes through. It makes sure the company claims every deduction and relief it qualifies for to avoid overpayment. It checks that the figures are supported and consistent, so the return is less likely to draw a query from IRAS.
The Accounts Are Not the Tax Figure
Your taxable income is not the same as your accounting profit. In Singapore, a tax agent prepares a tax computation that adjusts the profit in your accounts to the amount IRAS will tax. Some costs are added back, some are treated differently for tax, and any reliefs are then applied. The tax is worked out from this computation, not simply from the profit and loss statement. So, the profit shown to investors is often different from the figure used for tax.
Non-Deductible Costs Are Added Back
Not every expense in your accounts reduces your tax. The agent adds back the costs that are not deductible, such as private or personal expenses, fines, and the accounting depreciation of your equipment. A common example is the cost of a private car on an S-plate, which cannot be claimed. The agent goes through the accounts to catch these, because getting the list right keeps your return accurate and easy to defend.
Capital Allowances Replace Depreciation
The accounting depreciation is added back, but you do not lose the relief. In its place, the agent claims capital allowances, which are the tax version of depreciation for qualifying assets like machinery, computers, and office equipment. The rate depends on the type of asset. Claiming these correctly lowers your tax, and missing them means paying more than you need to.
Reliefs, Exemptions, and Losses
The agent applies whatever your company is entitled to. This includes any tax exemptions you qualify for, along with unused losses or capital allowances carried forward from earlier years. Carrying losses forward comes with conditions, such as the shareholding test, which the agent checks before making the claim. Missing a relief you are due is the same as paying too much tax.
The Right Form and the ECI Check
Before filing, the agent confirms which form applies to you. Form C-S is for smaller companies with revenue up to S$5 million that meet the conditions. Form C-S (Lite) is for those with revenue up to S$200,000, and Form C is for the rest. The agent also compares the final figures with the ECI you filed earlier in the year and explains any large difference. Filing the wrong form, or a figure that clashes with your ECI, can prompt questions from IRAS.
Supporting Records Behind Every Figure
Every claim on the return needs a record to back it up. A careful agent makes sure the receipts, invoices, and schedules behind your figures exist and match, because IRAS can ask to see them later. This is also the moment to fix anything missing in the bookkeeping before it reaches the return. Koh Management prepares the tax computation and the return as one job, checking the accounts and the supporting records before Form C is filed.
What This Means for You
A tax return is only as good as the checks done before it is filed. If you file it yourself, go through the tax computation, add-backs, capital allowances, and reliefs before submitting it. If a tax agent prepares it, ask to see the computation and how the final figure compares with your ECI. In either case, checking the figures before filing can help catch an error before it becomes a problem.
