Sri Lanka Personal Income Tax & APIT Slabs 2025/2026: The Complete Taxpayer Guide
Executive Summary
The enactment of the Inland Revenue (Amendment) Act No. 2 of 2025 represents the most substantive recalibration of Sri Lanka's personal income tax architecture since the post-crisis stabilization measures of 2022. By raising the personal relief threshold from Rs. 100,000 to Rs. 150,000 per month, widening the initial 6% bracket, and abolishing the 12% intermediate band, the law directly reduces the tax burden for over 450,000 formally employed professionals across the island.
1. Legislative Background & Constitutional Framework
Following Sri Lanka's macroeconomic debt restructuring program under the International Monetary Fund (IMF) Extended Fund Facility (EFF), the Inland Revenue Department (IRD) sought to balance revenue generation targets with the imperative of protecting real disposable incomes against cumulative inflation.
Under the former 2023/2024 regime, personal relief stood at a stringent Rs. 1,200,000 per annum (Rs. 100,000/month), with six equal slabs of Rs. 500,000 per annum (Rs. 41,666.67/month) taxed at escalating rates of 6%, 12%, 18%, 24%, 30%, and 36%. In response to widespread professional brain drain and cost-of-living petitions, the Parliament of Sri Lanka passed Amendment Act No. 2 of 2025 to re-anchor the tax threshold to contemporary living costs.
2. The 2025/2026 APIT Table 01 Progressive Slabs
Advance Personal Income Tax (APIT) is calculated on regular monthly employment profits using the official IRD Table 01 schedule. The table below illustrates the exact legal progression under the new statute:
| Tax Tier | Monthly Gross Range (LKR) | Slice Volume | Rate | Max Monthly Tax | Cumulative Tax |
|---|---|---|---|---|---|
| Personal Relief | Up to Rs. 150,000.00 | Rs. 150,000.00 | 0% | Rs. 0 | Rs. 0 |
| Slab 01 | Rs. 150,000.01 – 233,333.33 | Rs. 83,333.33 | 6% | Rs. 5,000.00 | Rs. 5,000.00 |
| Slab 02 | Rs. 233,333.34 – 275,000.00 | Rs. 41,666.67 | 18% | Rs. 7,500.00 | Rs. 12,500.00 |
| Slab 03 | Rs. 275,000.01 – 316,666.67 | Rs. 41,666.67 | 24% | Rs. 10,000.00 | Rs. 22,500.00 |
| Slab 04 | Rs. 316,666.68 – 358,333.33 | Rs. 41,666.67 | 30% | Rs. 12,500.00 | Rs. 35,000.00 |

4. Statutory EPF & ETF Deductions vs. APIT
A common point of confusion among salaried employees is whether EPF is deducted before or after income tax is assessed.
- Taxable Base: APIT is computed on your gross monthly employment earnings before EPF is subtracted.
- Employee EPF (8%): Deducted strictly from Basic Salary (and qualifying budgetary allowances).
- Employer Contribution (15%): The employer contributes 12% to EPF and 3% to ETF without reducing the employee's contracted gross wage.
- Net In-Hand Equation:
Net Pay = Gross Earnings - Employee EPF (8%) - Monthly APIT Withholding.
5. Employer Compliance & Mandatory Remittance Calendars
Every employer employing persons liable to APIT must hold an active Taxpayer Identification Number (TIN) and submit monthly schedules via the IRD RAMIS (Revenue Administration Management Information System) portal.
Monthly Remittance Deadline: On or before the 15th of the following month.
Annual Statement of Withholding: Filed by April 30th following the end of each Year of Assessment.
Penalties for Default: Up to 10% statutory surcharge plus 1.5% compounding monthly interest on overdue withholdings.
Frequently Asked Questions (FAQ)
Expert answers to top taxpayer queries grounded in Inland Revenue regulations.
What is the tax-free personal relief under the 2025 Amendment Act?
Under the Inland Revenue (Amendment) Act No. 2 of 2025, the tax-free personal relief for employment income is Rs. 1,800,000 per Year of Assessment, which translates to exactly Rs. 150,000 per calendar month. Individuals earning up to Rs. 150,000 monthly from regular employment pay zero (0%) Advance Personal Income Tax (APIT).
Why was the 12% intermediate tax slab repealed in 2025?
The government restructured the tax slabs to provide immediate relief to middle-income earners while simplifying the withholding structure. The 6% introductory tax slab was widened from Rs. 41,666.67 to Rs. 83,333.33 (combining the previous first two slices), after which taxable income directly enters the 18% slab, effectively eliminating the former 12% intermediate bracket.
How does Employee EPF (8%) affect my APIT calculation?
In Sri Lanka, APIT withholding is calculated on total gross employment remuneration (basic salary plus eligible allowances). Employee EPF (8%) is deducted from basic pay to arrive at Net Take-Home Salary: Net Salary = Gross Salary - Employee EPF (8%) - APIT Tax. EPF is not an upfront deduction against taxable gross income for monthly APIT withholding.
When must employers remit APIT deductions to the Inland Revenue Department?
Employers are required under Chapter VIII of the Inland Revenue Act No. 24 of 2017 to deduct APIT from qualifying employees monthly and remit the withheld taxes to the Commissioner General of Inland Revenue on or before the 15th day of the month immediately following the deduction.
Are non-cash benefits such as company vehicles or housing taxable?
Yes. Non-cash perquisites, including company-provided motor vehicles, fuel allocations, residential housing, and private utility allowances, have specific imputed valuation rates prescribed by the Inland Revenue Department and must be included in gross employment profits for APIT computation.
