RAMIS is the Inland Revenue Department's online system, and filing your individual income tax (IIT) return through it has been compulsory since the 2023/2024 Year of Assessment. This guide walks you through it screen by screen, in plain English. Last updated 2026-11-05.
Have these ready before you log in. Most of the time spent filing goes on finding documents, not on the forms. No TIN or PIN yet? The Access to e-Services page has links to obtain a TIN and request a PIN. Request them early, because you cannot file without them.
Go to ird.gov.lk. Under e-Services, choose Access to e-Services.
Select Individual Taxpayer and tap Proceed to Login. Enter your TIN, your PIN and the CAPTCHA exactly as shown.
Under Return / Schedule Management, select Individual Income Tax (IIT). If IIT is not listed, you are not yet set up for it: submit a request through the Taxpayer Registration tab (Tax type Registration Request). This often catches employees whose tax was only deducted as APIT. If IIT is listed but the year is missing, use the Return issuance tab to issue the return to yourself.
Select 2025/2026 and tap Proceed.
Select every type of income you had during the year and click Next. RAMIS uses your answers to send you to either the Simplified Return or the Standard Return.
In the Simplified Return, check the pre-filled employment and interest figures and correct them if needed. In the Standard Return, enter your income in Schedules 1 to 4, reliefs and qualifying payments in Schedule 5, withholding tax in Schedules 6 and 7, and tax credits such as APIT in Schedule 9. RAMIS calculates the tax in Schedule 8.
Declare what you owned and owed, in or outside Sri Lanka, as at 31 March 2026. These values are not used to calculate your tax, but the statement is part of the return.
Part A is for details of anyone who prepared the return for a fee, such as a tax consultant. Part B is your own declaration.
Every figure appears on the confirmation page. Use Amend to go back and fix anything. Print it or save it as a PDF before you submit: once submitted, you cannot view, print or edit the return.
Use Upload Supporting Documents to attach your certificates now, choosing the right document type, or submit the return and upload them later. Then press Submit.
If the return shows a balance tax payable after your credits, pay it by 30 November 2026. Payment details are available through Access to e-Services on the IRD website.
The Simplified Return is shorter and partly pre-filled. According to the IRD guide you can use it if your income is only from: If you have any other income, such as rent, business, freelance or foreign income, or you claim qualifying payments or reliefs beyond the personal relief, you must file the Standard Return. Pre-filled figures in the Simplified Return still need checking: the return is your own declaration.
Each schedule feeds the main return automatically. You fill in the schedules; RAMIS does the totals.
Yes. Under the Inland Revenue Act, individuals must file their income tax return electronically from the 2023/2024 Year of Assessment onwards, and RAMIS is the system used.
The IRD has said that returns for the 2025/2026 Year of Assessment must be filed electronically on or before 30 November 2026.
Go to ird.gov.lk and open Access to e-Services. It has links to obtain a TIN and to request a PIN. You need both your TIN and PIN to log in and file.
It means you are not yet set up for Individual Income Tax for that year. Submit a Tax type Registration Request through the Taxpayer Registration tab. If IIT is listed but the year is not, use the Return issuance tab.
Not on RAMIS: once submitted, you cannot view, print or edit the return. That is why you should check the confirmation page carefully and save a copy before you press Submit.
Yes. A tax consultant can prepare and file your return, and their details go in Part A of the declaration. EzBusiness tax consultants do this for individuals across Sri Lanka.
Often yes, especially if you had more than one employer, other income, or reliefs to claim. APIT is an advance payment, and the return is where it is credited against your final tax. If you are not sure, estimate your tax with our free calculator or ask us.
An EzBusiness tax consultant can prepare your return, claim every credit and relief, and file it on RAMIS for you. Fixed fees, and nothing is filed until you approve it.
This guide follows the IRD's Guide to e-Filing of Individual Income Tax (IIT) Return for Y/A 2024/2025 and the IRD's announcements for 2025/2026. Screens can change between years, so check the latest guidelines on the IRD website before you file.
