Guide for Sri Lankans in Australia: Tax liability & e-filing Y/A 2025/26 on taxcalculator.lk – understand residency rules, worldwide income taxation, and how to file through the IRD portal from overseas.
Sri Lankans living in Australia—whether permanent residents, temporary visa holders, or dual citizens—must carefully assess their Sri Lankan income tax obligations for the Year of Assessment (Y/A) 2025/2026.
Many assume that living abroad automatically removes Sri Lankan tax liability. However, under Sri Lanka’s income tax law, your physical presence in Sri Lanka determines your tax residency status—not your citizenship alone.
This comprehensive guide explains:
- Sri Lanka tax residency rules (183-day rule)
- Resident vs. non-resident taxation
- Filing obligations and income thresholds
- How to file your return from Australia
- Worldwide income implications
- Key updates for Y/A 2025/2026
- Practical compliance tips for Sri Lankan expats

Understanding the Sri Lankan Tax Year (Y/A 2025/2026)
The Sri Lankan tax year runs from:
1 April 2025 – 31 March 2026
This is different from Australia’s tax year (1 July – 30 June), so Sri Lankan expats must be careful when reconciling income between the two systems.
Tax returns for this period must be filed with the Inland Revenue Department (IRD) through its official online portal.
1. Tax Residency Rules for Sri Lankans in Australia
The 183-Day Rule (Most Important Test)
Your Sri Lankan tax residency depends primarily on physical presence.
You are considered a Sri Lankan tax resident if:
- You are physically present in Sri Lanka for 183 days or more during any 12-month period within the Year of Assessment.
If you meet this threshold during Y/A 2025/2026:
✔ You are taxed on worldwide income
✔ You must declare foreign employment income (including Australian salary)
✔ You must declare global assets and liabilities as of 31 March 2026
If you are present less than 183 days, you are generally treated as a non-resident.
Important Clarifications
1️⃣ Citizenship Does NOT Determine Tax Residency
- A Sri Lankan citizen living in Australia is typically a non-resident unless meeting the 183-day rule.
- Loss of Sri Lankan citizenship does not remove tax liability if Sri Lankan-sourced income exists.
- Non-citizens who previously lived in Sri Lanka follow the same residency rules.
2️⃣ Government Employees Abroad
Sri Lankan government employees posted overseas may still be treated as residents depending on circumstances.
2. Resident vs. Non-Resident: What Gets Taxed?
Your residency status determines the scope of taxation.
| Status | Tax Scope | Filing Trigger |
|---|---|---|
| Resident (183+ days in SL) | Worldwide income | Annual income exceeding LKR 1,800,000 |
| Non-Resident | Sri Lankan-source income only | Any taxable Sri Lankan income |
If You Are a Resident
You must declare:
- Australian employment income
- Australian business income
- Rental income (Australia or elsewhere)
- Dividends and foreign investment income
- Capital gains (if applicable)
From April 2025, certain foreign service income may be taxed at 15%, subject to law and treaty interpretation.
Residents must also declare:
- Assets and liabilities as of 31 March 2026
- Bank accounts (local and foreign)
- Properties
- Investments
- Loans
If You Are a Non-Resident
You are taxed only on Sri Lankan-sourced income, such as:
- Rental income from property in Sri Lanka
- Bank interest from Sri Lankan banks
- Dividends from Sri Lankan companies
- Business income generated in Sri Lanka
- Capital gains on Sri Lankan property
If you have zero Sri Lankan income, you typically do not need to file.
However, filing is recommended if:
- Income exceeds thresholds
- You expect future audits
- You are involved in property transactions
- You require tax clearance certificates
3. Filing Thresholds for Y/A 2025/2026
From April 2025:
- Monthly threshold: LKR 150,000
- Annual threshold: LKR 1,800,000
- Personal relief: LKR 1,200,000
If your income exceeds LKR 1.8 million annually and you are a resident, filing is mandatory.
Non-residents must file if they have taxable Sri Lankan-source income, regardless of threshold.

5. Double Taxation Considerations (Sri Lanka & Australia)
Sri Lanka and Australia have a Double Tax Agreement (DTA). If you are taxed in Australia on income also taxable in Sri Lanka, you may claim:
- Foreign tax credit (subject to conditions)
- Treaty benefits
Careful planning is required to avoid double taxation.
Professional advice is recommended for:
- Dual residency situations
- Foreign income structuring
- Complex asset disclosures
6. Common Mistakes Sri Lankan Expats Make
❌ Assuming no filing is required because living abroad
❌ Ignoring Sri Lankan rental income
❌ Not declaring foreign income when resident
❌ Forgetting asset disclosure requirement
❌ Missing filing deadlines
❌ Not maintaining documentation
7. Filing Deadlines
The IRD may announce deadlines and extensions. In previous years, extensions were granted (e.g., up to November 30 for prior years).
Always check announcements from the Inland Revenue Department.
Late filing may result in:
- Penalties
- Interest
- Compliance risk
8. Do You Need to File If You Are a Pure Non-Resident?
If:
- You stayed outside Sri Lanka the entire year
- You have zero Sri Lankan income
- No property, rent, business or bank interest
Then filing is generally not required.
However, if you:
- Plan to sell property
- Have inherited assets
- May be subject to audit
Voluntary compliance is advisable.
9. Practical Example
Example 1: Non-Resident Sri Lankan in Melbourne
- Stayed in Sri Lanka: 20 days
- Has rental income in Colombo: LKR 2,400,000 annually
➡ Must file in Sri Lanka
➡ Taxed only on rental income
➡ No need to declare Australian salary
Example 2: Resident Sri Lankan Working in Sydney
- Stayed in Sri Lanka: 190 days
- Earned AUD salary equivalent LKR 10M
- No Sri Lankan income
➡ Considered Sri Lankan tax resident
➡ Must declare worldwide income
➡ Australian income taxable in Sri Lanka (with possible foreign tax credit)
➡ Must declare assets/liabilities
