This is the general Sri Lanka tax calculator: it adds up salary, rent, interest and foreign income into one annual bill using the 2025/26 bands. If you only need your monthly payslip, use the salary calculator. If most of your income is foreign-currency freelance work, use the freelancer calculator, which applies the 15% rule in full. If you sold an asset, or you’re working out rent or FD interest on its own, use the advanced calculator.

Tax Calculator Sri Lanka
Salary, fixed deposits, rent, foreign clients, self-employment — or all of them at once. This free income tax calculator combines every source the way the IRD does, subtracts the tax already withheld from you, and tells you whether you need quarterly payments or just one annual return.
Where does your money come from?
Tap everything that applies to you — most people have more than one. Or
💼 Your salary
Your employer cuts tax from this every month (APIT). We check whether what they cut was enough.
Worked only part of the year — joined, resigned, or switched to your own work? Put the months here. Blank = all 12.
It’s on your payslip as “APIT” or “PAYE”. Blank = we estimate it from the official tax table.
💱 Money from foreign clients
If it arrived in foreign currency into your Sri Lankan bank, the law caps tax on it at 15%.
Rough is fine: monthly amount × 12, converted. USD 1,000 a month ≈ Rs. 3,600,000 a year.
🧾 Working for yourself
You’re taxed on profit — your earnings minus business costs. Company clients may have kept 5% back already.
Fees and sales for the year, minus what you spent to earn them — rent, helpers, materials, fuel.
🏠 Rent you collect
You’re taxed on rent after costs — choose how to handle repairs below.
Repairs and upkeep costs?
The law allows one or the other, not both. Pick whichever is bigger for you.
🏦 FD & savings interest
Interest counts as income. The bank already keeps 10% — but that’s an advance, not the final tax.
Not sure? Money in FDs × interest rate. Rs. 5,000,000 at 10% = Rs. 500,000 a year.
Bank usually keeps 10% = —

Calculate your total Sri Lanka income tax for Y/A 2025/26 across salary, freelance, rent, interest, and foreign income. The first Rs 1.8 million per year is tax-free; bands then run 6% to 36%, with remitted foreign-currency income capped at 15%.
Which calculator do you need?
2025/26 income tax slabs
| Taxable income band | Rate |
|---|---|
| First Rs 1,000,000 | 6% |
| Next Rs 500,000 | 18% |
| Next Rs 500,000 | 24% |
| Next Rs 500,000 | 30% |
| Balance | 36% |
These bands apply after your Rs 1.8 million personal relief. Rates set by the Inland Revenue (Amendment) Act No. 2 of 2025, effective 1 April 2025.
How this tax calculator works
You tap your income types and enter the numbers you already know — monthly salary, monthly rent, yearly totals for the rest. The calculator adds them into one assessable income, subtracts your Rs. 1.8 million personal relief, and applies the current bands — 6% on the first Rs. 1 million of taxable income, then 18%, 24% and 30% per Rs. 500,000 slab, and 36% above that. It then subtracts every rupee already withheld from you (APIT on salary, 5% AIT on professional fees, 10% on rent, 10% on interest) to show the number that actually matters: what’s left to pay — or what you’re owed back.
What each income source does in the calculation
| Income | How it’s taxed | Tax withheld from you |
|---|---|---|
| Salary | Normal bands; employer deducts monthly APIT | APIT per IRD Table 1 (auto-estimated, or enter your T-10 figure) |
| FD & savings interest | Normal bands — interest is assessable income, and the bank’s deduction is not a final tax | 10% AIT by the bank (creditable) |
| Rent | Normal bands after the automatic 25% rent relief for repairs & maintenance | 10% AIT if your tenant is a company paying over Rs. 100k/month |
| Foreign clients (FX) | Capped at 15% if received in FX and remitted through a Sri Lankan bank; normal bands otherwise | None — foreign clients don’t withhold |
| Self-employment (local) | Normal bands on profit after business expenses | 5% AIT by company clients above Rs. 100k/month |

Worked example: salary + two FDs
Nimal earns Rs. 250,000 a month and his fixed deposits paid Rs. 500,000 interest this year (banks deducted Rs. 50,000):
Salary Rs. 3,000,000 + interest Rs. 500,000
- Assessable incomeLKR 3,500,000
- Personal relief− LKR 1,800,000
- Taxable incomeLKR 1,700,000
- Tax (1M × 6% + 500k × 18% + 200k × 24%)LKR 198,000
- APIT already deducted (12 × 8,000)− LKR 96,000
- AIT on interest− LKR 50,000
- Balance to pay for the yearLKR 52,000
Because the Rs. 52,000 comes from investment income his employer can’t withhold on, Nimal is an instalment payer — about Rs. 13,000 a quarter. Without the FDs, his APIT alone would have settled everything, monthly.

Check the numbers before you file
These figures are estimates for a resident individual on Y/A 2025/26 rules, and simplify some edge cases: qualifying payments beyond personal relief, terminal benefits, capital gains, and the fine detail of the 15% FX computation (our method follows the IRD’s SET guide example, as no statutory formula exists). Always confirm your position with a Chartered Accountant or tax practitioner before paying or filing.

FAQ
Multi-income tax questions
What does this tax calculator work out?
+
It adds your salary, rent, interest and foreign income into one annual number, applies your Rs 1.8 million relief, then taxes the rest at 6% to 36%. It is the general calculator; use the other three for a single income type.
What counts as taxable income in Sri Lanka?
+
Salary, business and freelance profit, rent, interest, and foreign-currency income remitted through a Sri Lankan bank. Each is added together before the bands apply.
How much of my income is tax-free for 2025/26?
+
The first Rs 1.8 million a year, or Rs 150,000 a month if it's salary taxed through APIT. Everything above that is taxed at the 2025/26 bands.
I have a salary and freelance income. How are they combined?
+
They're added into one assessable income. Relief comes off the total, and the bands apply to the combined figure. Your APIT and any 5% withheld from your fees both count as credits.
Can I get withheld tax back?
+
If your APIT and AIT for the year add up to more than your final bill, the excess is refundable, but only if you file an annual return claiming it.
Which calculator do I need if most of my income is foreign currency?
+
Use the freelancer tax calculator. It applies the 15% cap on remitted foreign income and walks through the 5% withholding your clients already deducted.
The calculator shows the number. The return settles it.
