Annual ITR — November 30 Deadline (Individuals)

Deadline — November 30: The annual Income Tax Return (the "ITR" — the "Personal Income Tax Return" for the individuals) for the tax year ending December 31 must be filed by November 30 of the following year. For example: the ITR for the tax year 2025 (January 1 to December 31, 2025) must be filed by November 30, 2026.
E-filing — IRD portal: The ITR must be filed electronically through the "IRD e-Filing portal" (the "e-filing.ird.gov.lk" — the "Online Taxpayer Portal"). The paper filing is NOT accepted for the registered taxpayers. The taxpayer authenticates through the "TIN number" and the "password" (the "e-Filing credentials").
Tax return forms: The individuals use the "Form IIT" (the "Individual Income Tax Return") to report: (a) the employment income (the salary, the wages, the bonuses, the allowances, the benefits in kind), (b) the business income (the profits from the trade, the profession, or the vocation), (c) the investment income (the dividends, the interest, the royalties), (d) the rental income, (e) the capital gains, (f) the other income. The tax-free threshold for the individuals for 2026 is LKR 3,000,000 (the first LKR 3 million of the annual income is exempt from the IIT).
Payment deadline: The self-assessment tax (the "balance tax payable") must be paid by November 30 — the same date as the filing deadline. The taxpayer may pay in the instalments: the first instalment (the "advance tax") by August 15 and the second instalment (the "balance tax") by November 30.

VAT Returns — Monthly (by 20th of Following Month)

Filing frequency — monthly: The VAT-registered businesses must file the VAT return (the "VAT Return" — the "Form VAT 1") on the monthly basis. The return is filed by the 20th day of the month following the VAT taxable period. For example: the VAT return for January must be filed by February 20.
VAT return content: The VAT return includes: (a) the "output VAT" — the VAT charged on the taxable supplies (the sales) at the rate of 15%; (b) the "input VAT" — the VAT paid on the taxable purchases (the expenses) that is creditable; (c) the "net VAT payable" — the output VAT minus the input VAT; (d) the "VAT payments" — the VAT paid during the period; (e) the "VAT payable or refundable" — the net amount due or the overpayment.
E-filing — IRD VAT portal: The VAT return is filed through the "IRD e-VAT" system (the "VAT online portal"). The taxpayer must submit the "VAT return data" in the prescribed electronic format. The VAT payment must be made through the "online payment gateway" (the "e-Payment") by the filing deadline.

Withholding Returns (Monthly)

WHT obligations: The payer (the "withholding agent") must withhold the tax on the certain payments and remit the withheld tax to the IRD. The WHT (the "Withholding Tax") applies to: (a) the dividends — 14% (the standard rate) or 0% (the exempt dividends); (b) the interest — 5% (the resident individuals) or 14% (the resident companies and the non-residents); (c) the royalties — 10%; (d) the rent — 10% (the residents) or 20% (the non-residents); (e) the professional fees — 5%; (f) the payments to the non-residents — the applicable treaty rates.
Monthly WHT return: The withholding agent must file the monthly WHT return (the "WHT Return" — the "Form WHT 1") by the 15th day of the month following the payment. The return includes: the payee details (the name, the TIN, the address), the gross payment, the WHT rate, the tax withheld, and the date of the remittance.
Annual WHT certificate: The withholding agent must issue the annual "WHT certificate" (the "Form WHT 2") to each payee by January 31 of the following year. The certificate shows the total payments made and the total tax withheld during the year. The payee uses the certificate to claim the credit for the WHT against the own tax liability.

PAYE Returns (Monthly)

PAYE (Pay-As-You-Earn) system: The employer must deduct the "PAYE tax" (the "Pay-As-You-Earn" — the "withholding tax on the employment income") from the employee's salary and remit the tax to the IRD under the Section 115 of the IRA. The PAYE is the "monthly deduction" — the employer calculates the PAYE based on the employee's monthly salary using the PAYE tax tables issued by the IRD.
PAYE return — monthly: The employer must file the monthly PAYE return (the "PAYE Return" — the "Form PAYE 1") by the 15th day of the month following the salary payment. The return includes: the employee details (the name, the NIC, the TIN), the gross salary, the PAYE deducted, the EPF/ETF contributions, and the net salary paid.
Annual PAYE reconciliation: The employer must submit the annual "PAYE reconciliation statement" (the "Form PAYE 2") by January 31 of the following year, reconciling the monthly PAYE deductions with the annual salary data. The employer must issue the annual "PAYE certificate" (the "Form PAYE 3") to each employee showing the total salary and the total PAYE deducted.

e-Filing via IRD Portal (IIT, VAT, CIT)

IRD e-Filing portal: The "IRD e-Filing portal" (the "e-filing.ird.gov.lk" — the "Online Taxpayer Portal") is the central online platform for the tax filing in Sri Lanka. The portal supports: (a) the "IIT" — the Individual Income Tax Return (Form IIT), (b) the "CIT" — the Corporate Income Tax Return (Form CIT), (c) the "VAT" — the Value Added Tax Return (Form VAT 1), (d) the "WHT" — the Withholding Tax Return (Form WHT 1), (e) the "PAYE" — the Pay-As-You-Earn Return (Form PAYE 1), (f) the "SDL" — the Skills Development Levy Return (Form SDL 1), (g) the "ESC" — the Economic Service Charge Return (Form ESC 1).
Registration for e-Filing: The taxpayer must register for the e-Filing through the "IRD Self-Care Portal" (the "Portal"). The registration requires: the TIN, the valid email address, the mobile phone number, and the business registration details (if applicable). The IRD issues the "e-Filing credentials" — the username and the password for the portal access.
Features: The e-Filing portal provides: (a) the "pre-populated data" — the IRD pre-populates the salary data from the PAYE returns, the bank interest data, and the investment data; (b) the "online payment" — the integration with the "e-Payment" gateway for the tax payment (the credit card, the debit card, the internet banking); (c) the "tax calculation" — the automatic tax calculation based on the submitted data; (d) the "submission confirmation" — the instant acknowledgement of the filing; (e) the "return download" — the PDF copy of the filed return.

Assessments and Appeals

IRD assessment process: After the filing of the tax return, the IRD may issue: (a) the "self-assessment" — the tax calculated by the taxpayer is accepted by the IRD; (b) the "deemed assessment" — if the taxpayer fails to file the return, the IRD issues the assessment based on the estimated income (the "best of judgment assessment"); (c) the "additional assessment" — if the IRD discovers the omission or the understatement, the IRD issues the additional assessment within 4 years of the end of the tax year (6 years in the case of the fraud or the wilful default).
Objection and appeal: The taxpayer who disagrees with the IRD assessment may: (a) file the "notice of objection" (the "Form O" — the "Objection Form") with the IRD within 30 days of the receipt of the assessment; (b) request the "internal review" by the IRD "Objections Division" — the IRD must issue the "determination" within 120 days of the objection; (c) appeal to the "Tax Appeals Commission" (the "TAC" — the independent appellate body) within 30 days of the IRD determination; (d) appeal to the "Court of Appeal" on the question of the law within 60 days of the TAC decision.
Taxpayer's Charter: The IRD has published the "Taxpayer's Charter" — the statement of the taxpayer's rights: (a) the right to the fair treatment, (b) the right to the confidentiality, (c) the right to the representation, (d) the right to the reasonable time to comply, (e) the right to the review and the appeal, (f) the right to the refund of the overpaid tax.

Penalties for Late Filing — 2.5% Per Month

Late filing penalty — 2.5% per month: The taxpayer who fails to file the tax return by the due date is subject to the "late filing penalty" (the "default penalty") at the rate of 2.5% per month (or the part thereof) of the unpaid tax, calculated from the due date to the date of the filing. The maximum penalty is 100% of the unpaid tax (the penalty is capped at the amount of the tax due).
Late payment penalty — 2.5% per month: The taxpayer who files the return but fails to pay the tax by the due date is subject to the "late payment penalty" at the rate of 2.5% per month on the unpaid tax, calculated from the due date to the date of the payment. The late payment penalty is separate from the late filing penalty.
Other penalties: The IRA prescribes the additional penalties for: (a) the failure to register for the tax — LKR 50,000; (b) the failure to maintain the records — LKR 100,000; (c) the failure to withhold the tax — 50% of the tax that should have been withheld; (d) the false or misleading statement — LKR 200,000 or 100% of the tax understated; (e) the tax evasion — the criminal prosecution with the imprisonment up to 5 years and the fine up to LKR 5 million.
