Tax Submission Reminder for Companies with December Year-End

Important Tax Deadline for YA 2025

If your company’s financial year ended on 31 December 2025, it is time to ensure that your Company Tax Return (Form C) and related tax matters are properly prepared and submitted.

For companies with a 31 December 2025 year-end, the key deadline to take note of is:

30 November 2026 — Form C Submission Deadline

Companies are required to submit their tax return for Year of Assessment (YA) 2025 within the prescribed deadline.

What Should Your Company Prepare?

To avoid last-minute delays, businesses should ensure that the following information is ready:

  • Audited or unaudited financial statements, where applicable
  • Trial balance and general ledger
  • Tax computation
  • Fixed asset schedule
  • Capital allowance schedules
  • Details of business expenses
  • Supporting documents for significant expenses
  • Details of related-party transactions, where applicable
  • Prior-year tax computation and supporting schedules
  • CP204 instalment information
  • Relevant tax adjustments and supporting documents

Why Should You Start Early?

Tax preparation should not be left until the submission deadline.

The preparation of the tax computation may require a review of the company’s financial statements and adjustments for tax purposes.

Some common areas that may require attention include:

Accounting profit ≠ Taxable income

Not every accounting expense is automatically deductible for tax purposes. Certain expenses may need to be added back, while qualifying capital expenditure may be considered for capital allowances.

Examples include:

  • Depreciation
  • Non-deductible expenses
  • Entertainment expenses
  • Private or non-business expenses
  • Provisions and impairment losses
  • Donations
  • Capital expenditure
  • Foreign exchange differences
  • Other specific tax adjustments

Don’t Forget Your Supporting Documents

Proper documentation is important when preparing the company’s tax computation.

Businesses should retain relevant invoices, receipts, agreements, payment records and other supporting documents to substantiate their income and expenses.

Incomplete records can result in additional queries and may make the tax computation process more time-consuming.

Review Your Tax Position Before Submission

Before submitting Form C, companies should consider reviewing:

☑ Financial statements are finalised

☑ Tax computation has been prepared

☑ Tax adjustments have been reviewed

☑ Capital allowances have been updated

☑ Tax instalments are reconciled

☑ Tax payments and outstanding balances are checked

☑ Supporting documents are available

☑ Form C information agrees with the company’s financial records

Avoid Last-Minute Submission

Waiting until the final days to prepare the tax return can create unnecessary pressure, particularly where the financial statements, tax computation or supporting documents still require clarification.

Starting early gives your company sufficient time to identify discrepancies, obtain missing documents and resolve tax adjustments before submission.
