Foreign APIT Calculator (Basic)🇱🇰

Foreign APIT Calculator (Sri Lanka)

Estimate your monthly Advance Personal Income Tax (APIT) on foreign employment income as a Sri Lankan resident. This calculator converts your monthly income from a supported foreign currency to LKR using an exchange rate for the selected date, then applies the appropriate APIT slabs for a simple monthly estimate.

Who this tool is for

This tool is designed for Sri Lankan resident employees who are physically present in Sri Lanka but receive employment income from a foreign employer. It follows the guidance in the IRD table “Rate for the deduction of tax from the employment income received from foreign employer.” Freelancers and independent service providers are out of scope because their income is typically treated as business income under different rules.

Supported currencies

AUD, CAD, EUR, GBP, NZD, SGD, USD

What you can do

• Convert your monthly foreign currency income to LKR using the historical rate on the date you were paid
• Override the exchange rate manually if needed (for example, if you used a bank-specific rate)
• See a monthly APIT estimate in LKR with a clear slab-wise breakdown
• View your effective tax rate for quick comparison

Inputs

• Foreign Currency: one of AUD, CAD, EUR, GBP, NZD, SGD, USD
• Date Received: the date the income arrived; used for exchange-rate lookup
• Monthly Foreign Currency Income: your monthly gross income for the selected month
• Exchange Rate: auto-fetched from our dataset for the selected date; editable

Outputs

• Monthly Income (LKR): your foreign income converted using the rate shown
• Monthly APIT (LKR): estimated monthly APIT on the converted amount
• Effective Tax Rate: APIT ÷ LKR income, expressed as a percentage
• Slab Breakdown: clear allocation across the relevant slabs for this monthly estimate

How the tax is calculated

This basic calculator applies monthly slabs derived from the annual thresholds in the IRD specification:

• 0% on the first Rs. 150,000 (annual Rs. 1,800,000 ÷ 12)
• 6% on the next Rs. 83,333 (annual Rs. 1,000,000 ÷ 12)
• 15% on the remainder

This is a simplified monthly-only view for estimation. The Inland Revenue Act requires APIT to be determined using cumulative income across the Year of Assessment (Y/A: April 1 – March 31), where monthly payable tax equals the current cumulative tax liability minus cumulative APIT already paid. We will provide that full cumulative approach in an advanced version of this tool.

Exchange-rate source

• By default, rates are loaded from our curated historical dataset. If the exact date is not present, the closest or latest available rate is used.
• You may manually edit the rate to reflect bank-specific or contract-specific rates.
• Our shared exchange-rate component also supports live API fetches with caching (used in the Currency Converter), so future versions may enable API fetching here as well.

Example (illustrative)

Assume you received USD 6,000 on a date where the USD/LKR rate is 300.75.

• LKR Income ≈ 6,000 × 300.75 = Rs. 1,804,500
• Slab allocation (monthly):
  • 0% on Rs. 150,000 → Rs. 0
  • 6% on next Rs. 83,333 → Rs. 4,999.98
  • 15% on remaining Rs. 1,571,167 → Rs. 235,675.05
• Estimated Monthly APIT ≈ Rs. 240,675.03
• Effective Rate ≈ 240,675.03 ÷ 1,804,500 ≈ 13.34%

Values above are rounded for readability. Your actual result may vary depending on precise rate and date.

Important notes & limitations

• This version does not compute the cumulative Y/A method required by law; it’s for monthly estimates only.
• This tool is country-specific (Sri Lanka). If your country selector is not set to Sri Lanka, you’ll see a notice.
• This tool does not consider allowances, deductions, or tax credits. It focuses on the foreign employment income table only.
• Always use official IRD guidance and consult a qualified tax professional for personal advice.
