This calculator turns a Sri Lankan monthly salary into Advance Personal Income Tax (APIT), EPF, ETF and take-home pay, using the Inland Revenue Department's Tax Table No. 01 and the EPF and ETF rules.
APIT. Tax Table No. 01 covers regular pay from a primary employment for residents and Sri Lankan citizens. The Rs. 150,000 monthly personal relief is already built in, and nothing else is deducted first: not even EPF. The summarized table reads:
| Monthly pay (Rs.) | APIT |
|---|---|
| up to 150,000 | nil |
| 150,001 to 233,333 | 6% of pay less 9,000 |
| 233,334 to 275,000 | 18% of pay less 37,000 |
| 275,001 to 316,667 | 24% of pay less 53,500 |
| 316,668 to 358,333 | 30% of pay less 72,500 |
| above 358,333 | 36% of pay less 94,000 |

Employers use IRD Tax Table No. 01, which already allows the Rs. 150,000 monthly personal relief. Pay up to Rs. 150,000 is tax-free. Above that the tax is a percentage of the whole monthly pay less a fixed sum: 6% less Rs. 9,000 up to Rs. 233,333, rising to 36% less Rs. 94,000 above Rs. 358,333.
No. Table No. 01 says the tax is worked out on the profits from employment without deducting any sum, so the employee's 8% EPF does not lower APIT. On Rs. 250,000 a month the APIT is Rs. 8,000 on the full Rs. 250,000, and EPF of Rs. 20,000 comes off separately.
EPF is at least 8% of total monthly earnings from the employee and at least 12% from the employer, 20% in all. ETF is 3% of the same earnings, paid by the employer alone. On Rs. 100,000 a month: Rs. 8,000 from the employee, Rs. 12,000 of EPF and Rs. 3,000 of ETF from the employer.
Rs. 300,000 a month falls in the 24% row of Table No. 01: 24% of 300,000 is Rs. 72,000, less Rs. 53,500, so APIT is Rs. 18,500. With 8% EPF of Rs. 24,000 the take-home pay is Rs. 257,500, if all the pay counts as EPF earnings.
