How this is calculated
Taxable income = Gross salary − (optional employee EPF at 8%).
The first LKR 150,000 per month is tax-free (personal relief). Income above that is taxed in slabs of LKR 41,667: 6%, 12%, 18%, 24%, 30%, with the balance at 36%.
You can override the relief in the form. If IRD changes the slab structure, these calculations should be recalibrated.
Frequently asked questions
Which tax slabs does this use?
It uses the Sri Lanka Inland Revenue Department PAYE slabs commonly published for the current period, with a monthly personal relief. Slabs are configurable above so you can update them if IRD revises them.
Is EPF/ETF deducted before tax?
Employee EPF (typically 8%) is deducted from gross to get taxable income in most payroll setups. Toggle the EPF option above to include or exclude it.
Are bonuses included?
The default assumes a regular monthly salary. For lump-sum bonuses, tax may be calculated differently by your employer.
Does this replace official IRD calculations?
No. This is an indicative estimate. For binding figures, use your employer's payroll or the IRD calculator.
