What AI Account's Tax Computation Covers
Tax paperwork becomes a high-stakes compliance task when your books, forms and filing responsibilities span Singapore and Malaysia. AI Account prepares and generates Singapore and Malaysia tax computations in one click from your posted books. This page explains what the feature covers, the official filing schedule and how your company keeps control of filing.
Tax computation is part of AI Account's compliance software:
- Tax computation prepared and generated in one click from the posted ledger
- Singapore: tax computation, Estimated Chargeable Income (ECI), and Form C-S, Form C-S (Lite) or Form C
- Capital allowances and other tax adjustments worked out automatically
- Malaysia: tax computation, CP204 estimate of tax payable and Form C (e-C)
- Built on the same books as your financial statements
What Do IRAS and LHDN Require for Tax Computation and Filing?
IRAS states that a tax computation is the statement that adjusts accounting profit for tax purposes to reach the income chargeable to tax. ECI is filed within 3 months of the financial year end unless the company qualifies for the ECI filing waiver. Companies file Form C-S, Form C-S (Lite) or Form C. Form C-S is for qualifying Singapore-incorporated companies with annual revenue of $5 million or below. Form C-S (Lite) is for those with revenue of $200,000 or below. Companies filing Form C submit financial statements and a tax computation. Form C-S and Form C-S (Lite) filers keep them ready in case IRAS asks.
LHDN requires Form CP204, the estimate of tax payable, to be e-filed no later than 30 days before the basis period begins. Form C (e-C) is due 7 months after the accounting period closes.
Each of these filings depends on figures that already sit in your accounts. Preparing the computation from the posted ledger keeps it aligned with the books the filing relies on, instead of a separate workbook that drifts out of date. Rules change, so confirm the current dates with IRAS and LHDN before each filing cycle.
How AI Account Generates Your Tax Computation
Once the period's transactions are posted, one click prepares the computation, with capital allowances and the other tax adjustments worked out automatically. You review it, then your company files through IRAS or LHDN. The four points below describe what you get.
1. Adjustments and capital allowances worked out for you
There is no separate tax workbook to build. A tax computation begins with the accounting profit, and in AI Account that figure already sits in your posted books. AI Account then works out the tax adjustments, including capital allowances, automatically, so your time goes on reviewing the result rather than building it.
2. Singapore documents, ready for review
For Singapore, AI Account prepares the tax computation, ECI, and Form C-S, Form C-S (Lite) or Form C, whichever your company files. ECI is the estimate of chargeable income due within three months of the financial year end. Form C-S, Form C-S (Lite) and Form C are the annual Corporate Income Tax Returns. Form C is filed with the financial statements and the tax computation.
3. Malaysia documents, ready for review
For Malaysia, AI Account prepares the tax computation, the CP204 estimate of tax payable and Form C. CP204 sets the estimate for the coming year of assessment, and Form C is filed through e-C.
4. One set of books, your filing
Every document uses the same books as your financial statements. The capability is included in the Premium and Customise plans at no extra charge. Your company submits filings through IRAS or LHDN, because AI Account is software and never files on your behalf. GST and SST are handled separately in the tax compliance module, with their own tax codes and reports.
