What you need for your tax file.
A plain-English checklist of every document and detail the IRD asks for — organised by your situation, not by their forms. Use it to file yourself, or to walk into your accountant’s office without leaving anything behind.
You must file if you
- Earned more than Rs. 1,800,000 in 2025/26
- Receive interest income where AIT was deducted (banks)
- Run a business, profession, or sole proprietorship
- Earn rental income from property you own
- Are a director receiving fees from a company
- Are already registered with the IRD and have a TIN
You probably don't need to file if
- You’re salaried under Rs. 1.8M and have no other income
- Your only income was bank interest below the threshold
- You’re a student or unemployed with no taxable income
- You’re filing a “Nil Return” — even then, it’s optional
Not sure where you fall? The numbers below tell the truth — gather what applies, total it up, and you’ll know.
The basics — everyone needs these
No matter how simple or complex your return is, start here. Without these you can’t submit anything.
🆔
Your TIN
Taxpayer Identification Number — issued by the IRD
›
Every individual filing in Sri Lanka needs a TIN. If you’ve ever paid PAYE/APIT through your employer, you almost certainly have one — check an old payslip or your APIT certificate. If you don’t have one, register through the IRD e-Services portal or visit your nearest IRD regional office.
- TIN number — 9 digits, often printed on payslips and APIT certs
- e-Services login — username and password for ird.gov.lk
- NIC — for verification, especially if filing on someone else’s behalf
📅
The right year of assessment
2025/26 covers 1 April 2025 to 31 March 2026
›
Sri Lanka’s tax year doesn’t follow the calendar year. When IRD says “Y/A 2025/26,” they mean everything that happened between 1 April 2025 and 31 March 2026. The return is due by 30 November 2026. File late and the penalty is Rs. 50,000 plus Rs. 10,000 per additional month.
Money you earned
Find every source of income that applied to you between April 2025 and March 2026. For each one, gather the document that proves the number.
💼
Salary, wages, bonuses
Employment income — what your employer paid you
›
Your employer should have deducted APIT (Advance Personal Income Tax) every month and given you an annual certificate. The T10 is the single most important document for salaried filers — the IRD has matching records, so the number must agree.
- T10 / Statement of Tax Deducted from each employer for 2025/26
- March 2026 payslip — for cross-checking annual totals
- Gross remuneration — salary + bonus + allowances + non-cash benefits (housing, vehicle, fuel, mobile)
- EPF / ETF deducted during the year
- PAYE / APIT withheld during the year
- Employment start and end dates within the year (if you changed jobs)
- If you changed jobs: T10 certificates from every employer in the year
🎁
One-time retirement payouts
Gratuity, EPF lump sum, ETF lump sum, VRS / commuted pension
›
One-off payments on retirement, termination, or migration are taxed differently from monthly salary. Each payout needs its own paper trail — payer, gross amount, date received, and any tax already withheld.
- Approval / retirement letter — EPF approval, retirement letter, VRS offer
- Payment advice — bank credit advice or final payslip showing the gross amount
- Tax certificate — only if tax was deducted at source
- Date the payment was received (the date matters for the year of assessment)
- Payer name — employer, EPF / Trustee, ETF Board
👴
Pension
Public, private, or foreign retirement income
›
Government pensions (Department of Pensions, W&OP) are exempt from income tax but still need to be declared. Private and foreign pensions are taxable — check the certificate carefully.
- Annual pension statement from the Department of Pensions or your provider
- WHT certificate — if tax was deducted at source
- Pension type — public (Govt / W&OP), private employer scheme, or foreign
- Gross pension received during the year
🏦
Bank interest
Savings, current accounts, fixed deposits, FCY accounts
›
Banks deduct WHT (typically 10%) on most interest payments and issue a certificate for the year. Collect one from every bank and account you held — including ones you closed mid-year.
- Bank name, branch, account type (savings, current, FD, FCY) and last 4 digits
- Opening balance at 1 April 2025 and closing balance at 31 March 2026
- Gross interest earned during the year
- WHT certificate from the bank (if WHT was deducted)
- Bank statements covering the full year (April 2025 — March 2026)

- Realised earnings during the year (distributions plus realised redemptions)

Dividends (CSE)

Anything else
Royalties, prizes, casual income, gifts, side hustles
›
If you received money during the year and it doesn’t fit any other box — royalties, lottery winnings, casual fees, gifts above Rs. 50,000, online platform payouts — note it down. Better to mention it and let your accountant decide.
- Statement — whatever paperwork accompanied the money
- WHT certificate — if any tax was withheld
- Supporting evidence — agreements, royalty schedules, prize letters
- A short description, gross amount, and any notes for your accountant
What you owned and what you owed (at 31 March)
The IRD asks for a snapshot of your wealth at the end of the year, called the Statement of Assets & Liabilities. This catches most first-time filers off guard. The numbers don’t have to be exact — they have to be reasonable and consistent.
🏘
Immovable property
Land, houses, apartments — in Sri Lanka or abroad
›
- Address and a brief description (extent of land, type of building)
- Date acquired and how (purchase, gift, inheritance)
- Original cost — what you paid, in rupees

🚗
Vehicles
Cars, vans, bikes, boats — anything registered in your name
›
- Make, model, year, registration number
- Date acquired and original cost
- Revenue licence and registration certificate (CR book) reference
💵
Bank deposits and cash
Every account, plus cash in hand
›
- Bank name, branch, account type (savings / current / FD)

- T-bill and T-bond holdings statements
💍
Gold, jewellery, gems
Reasonable estimate is fine — don't overthink it
›
Most people use a rough estimate of total value. If you have valuation certificates from a jeweller, use those. The number should be consistent year on year unless you genuinely bought or sold something significant.
🤝
Loans you've given out
Money owed to you by others at year-end
›
- Who owes you, how much, since when
- Any written acknowledgement or agreement
📉
Liabilities — what you owe
Bank loans, mortgages, credit cards, personal debts
›
- Lender name (bank, finance company, person)
- Original loan amount and date
- Outstanding balance at 31 March 2026 — get a statement from your bank
- Interest rate and remaining term
- What the loan was for — house, vehicle, business (matters for deductions)
Things that reduce your tax
Personal relief is automatic. Everything else needs evidence — and most filers leave money on the table because they didn’t keep receipts.
✨
Personal relief — Rs. 1,800,000
Automatic for resident individuals
›
Every resident individual gets Rs. 1,800,000 deducted from assessable income before tax is calculated. You don’t claim it — it’s automatic. (Trustees, executors, and liquidators don’t get it.)
💝
Charitable donations
To approved charities and the government
›
Donations to approved charities are deductible up to one-third of taxable income or Rs. 75,000, whichever is lower. Donations to the government can have a higher cap.
- Receipts from each charity, with their approval reference
- For government donations: official acknowledgement letter
☀
Solar power installation
Rooftop systems for your home or business
›
- Installation invoice from a registered installer
- Bank-confirmed payment proof
- CEB net-metering / net-accounting agreement
🏥
Health insurance, life insurance, education
Limited circumstances — check eligibility
›
Some health, life-insurance, and education-related expenditure qualifies under specific rules that change frequently. Bring premium receipts and tuition statements if you have them — your accountant or our software can tell you what’s claimable for the current year.
Anything you bought or sold
A vehicle, a piece of land, a chunk of shares, a fixed deposit that matured — if it changed hands during the year, the IRD wants to see it. Capital gains on certain assets are taxable; even non-taxable disposals need to be declared.
🛍
Things you bought
Acquisitions during 2025/26
›
- What it is — vehicle, land, shares, etc.
- Date acquired
- How much you paid
- How you funded it (savings, loan, gift, inheritance)
- Sale agreement, deed, or invoice
📤
Things you sold
Disposals — these may trigger capital gains tax
›
- What it was, when you originally bought it, what you originally paid
- Date of sale and sale price
- Costs of sale (broker, lawyer, stamp duty)
- Any improvements you made before selling (with receipts)
The things that catch people out
These aren’t “income” or “assets” exactly — but they belong on your return, and forgetting them is what causes most amendments and penalties.
📱
Side hustles you weren't sure counted
Tutoring, consulting, online sales, content, ride-sharing
›
If you earned anything outside of your main job — even occasionally, even paid in cash, even via PayPal or international platforms — it’s income. Better to declare it than to have a bank deposit pattern that doesn’t match your declared income.
👪
Joint accounts and family money
Whose income is it, really?
›
Interest on a joint FD, rent from a property in your spouse’s name, money sent home by family — who declares what depends on legal ownership, source, and intent. Make a list of joint or family-related amounts so your accountant can split them correctly.
📥
Money received from abroad
Family remittances, freelance payments, gifts
›
Different rules apply depending on whether the money is a gift, a loan, employment income, or business income. Your bank has records of every inward remittance — the IRD can request these.
📜
Last year's return
Your starting point for assets and any carried-forward credits
›
If you filed last year, this year’s opening assets must match last year’s closing assets. Any unused tax credits or losses carry forward. Pull up the PDF — it’ll save you an hour of guesswork.
