Income tax return questions, answered

  • Do I need to file an income tax return in Sri Lanka?

    It depends on your total income for the year of assessment and your circumstances, for example employment income from more than one source, or rental, business, freelance or foreign income. The IRD sets the thresholds and they can change, so when we review your documents we confirm your position for the relevant year.

  • What is the deadline?

    The final income tax return for the 2025/26 year of assessment is due by 30 November 2026. The IRD sets the deadlines and they can change, and income tax is usually paid in instalments during the year. We remind you before every deadline.

  • What if I missed a past deadline?

    Late returns can attract penalties and interest, so it is better to deal with them sooner rather than later. We can review which years are outstanding, prepare the returns and explain what is payable. We cannot promise that any penalty will be reduced or waived.

  • How long does filing take?

    It depends on how many income sources you have and how quickly we receive your documents and your approval. We give you an estimate once we have looked at your documents, and we always ask you to approve the return before it is filed.

  • Can you file for my spouse as well?

    Yes. Each person is assessed individually, so your spouse's return is prepared separately from their own documents and with their approval. We can handle both at the same time.

  • What are APIT and WHT, and how are the credits claimed?

    APIT (Advance Personal Income Tax) is tax your employer deducts from your salary. WHT (withholding tax) is tax deducted at source from payments such as bank interest. The employer or payer gives you a certificate, and the tax already deducted is claimed as a credit against the tax on your return. We match your certificates to your return.

  • What if the IRD contacts me afterwards?

    If the IRD sends a query or notice about a return we filed, send it to us. We will help you understand what is being asked and prepare a response. We cannot influence the IRD's decisions or the outcome.

  • Is my data kept confidential?

    We use your documents and details only to prepare and file your return and to contact you about it, and we handle them in line with our Privacy Policy.
