Quick answer
A Malaysian company must furnish its return of income (Form C or C-S) within seven months from the date following the close of its accounting period (Income Tax Act 1967, s.77A), and submit an estimate of tax payable (CP204) at least 30 days before the basis period begins, not less than 85% of the previous year's revised estimate (s.107C). This service covers tax computation, Form C / C-S and CP204. Fees depend on the company's size and complexity and are quoted on request.

Overview
Company tax in Malaysia is self-assessed. The company works out its chargeable income and tax, files the return, and LHDN treats the return as an assessment — which puts the responsibility for accuracy on the company.
Two statutory cycles run together. Section 77A requires the return (Form C, or Form C-S for qualifying small companies) within seven months after the accounting period ends. Section 107C requires an estimate of tax payable (CP204) at least 30 days before each basis period begins, paid in monthly instalments, with the estimate not lower than 85% of the previous year's revised estimate; it can be revised during the year with CP204A.
Most tax penalties we see are not about complex issues — they come from late filing, under-estimated CP204 instalments, or a return prepared before the audit is final. We work from your audited or final accounts and plan the CP204 so the instalments and the final tax stay in line.

Frequently asked questions
What if our CP204 was too low?
It can be revised with CP204A during the year; large shortfalls attract penalties.
Can we file before the audit is done?
The return should be based on final accounts; filing early on draft figures risks amendments.
Why is there no fixed price?
It depends on your accounts' size and complexity, so we quote after review.
