Tax on Tax: Grossing Up Employer-Paid APIT

Tax on tax means the employer pays the employee's APIT. The IRD's Table 6 grosses this up. See the full rates, a worked example and the T10 entry.

Tax on tax means the employer pays the employee’s income tax (APIT) without deducting it, or pays back tax already deducted. The IRD treats that payment as a benefit to the employee. So the employer must also pay tax on the tax it just paid. This is worked out with the IRD’s own Table 6, not by trial and error.

Why this happens

A job offer can promise a net salary. The employer then pays the tax on top, so take-home pay is fixed. The moment the employer pays that tax, the payment is itself taxable income. Taxing it creates an extra tax bill. That extra bill is tax on tax, or “grossing up”.

Which table applies

Table 6 has three parts, for three situations. Each one works from the employee’s remuneration (the Act’s word for salary or wages, including cost-of-living allowance, overtime pay and prescribed allowances). Use the one that matches your case.

Table 6.1: monthly pay

Read the tax the employer must pay straight off this table. No separate grossing-up sum is needed. “Relief from tax” means no tax is due.

Monthly remuneration (LKR)Tax payable by the employer
0 – 150,000Relief from tax
150,001 – 228,333(Monthly remuneration × 6.38%) − 9,570
228,334 – 262,500(Monthly remuneration × 21.95%) − 45,119
262,501 – 294,167(Monthly remuneration × 31.58%) − 70,398
294,168 – 323,333(Monthly remuneration × 42.86%) − 103,580
323,334 and above(Monthly remuneration × 56.25%) − 146,875

Worked example: gross LKR 300,000 a month

Mr. De Silva earns LKR 300,000 a month. His employer has agreed to pay his tax, not deduct it from his pay. LKR 300,000 falls in the 294,168–323,333 band.

Tax payable by the employer = (300,000 × 42.86%) − 103,580 = 128,580 − 103,580 = LKR 25,000 for the month.

Table 6.2: a bonus or other lump sum

A bonus taxed under Table 2, the table for a bonus or lump sum uses the year’s cumulative pay, not just the bonus month. Grossing up a bonus works the same way. First find the EGAR (Estimated Gross Aggregate Remuneration), marked D: pay already paid this tax year, plus pay still to come, plus every lump sum paid or payable. Then apply the matching band below.

EGAR for the year (D)Tax deductible on the lump sum
D ≤ 1,800,000Nil
1,800,001 – 2,740,000(D × 6.38%) − [114,840 + Table 6.1 tax on pay already paid + Table 6.1 tax on pay still due + tax deducted earlier on lump sums]
2,740,001 – 3,150,000(D × 21.95%) − [541,430 + the same three amounts]
3,150,001 – 3,530,000(D × 31.58%) − [844,770 + the same three amounts]
3,530,001 – 3,880,000(D × 42.86%) − [1,247,958 + the same three amounts]
Over 3,880,000(D × 56.25%) − [1,762,500 + the same three amounts]

Worked example: a LKR 600,000 bonus

Mr. Dayananda earns LKR 180,000 a month, unchanged for the year. His employer pays his tax on a LKR 600,000 bonus in April, month one of the tax year.

  • A (pay already paid, April) = LKR 180,000
  • B (pay still to come, May to March) = LKR 180,000 × 11 = LKR 1,980,000
  • C (the bonus) = LKR 600,000
  • D = 180,000 + 1,980,000 + 600,000 = LKR 2,760,000, in the 2,740,001–3,150,000 band

Monthly tax-on-tax on LKR 180,000 under Table 6.1 is (180,000 × 6.38%) − 9,570 = LKR 1,914.

Tax on the bonus = (2,760,000 × 21.95%) − [541,430 + (1,914 × 1) + (1,914 × 11)] = 605,820 − 564,398 = LKR 41,422.

Non-resident staff on a second job

Table 6.3 covers only one case: a non-resident employee’s secondary employment. The employer’s tax there is a flat sum: monthly remuneration from that job × 56.25%, on any amount. Table 6 does not cover grossing up a non-resident’s main job. Ask the IRD before you apply Table 6 to that case. See payroll for foreign employees in Sri Lanka for the wider rules on that payroll.

What the payslip and the T10 show

The employer remits this tax the same way it remits any other APIT. It appears on the payslip and feeds into the employee’s T10 certificate at year end, the same as normal Table 1 or Table 2 tax. Every employer stays a withholding agent under section 83 of the Inland Revenue Act No. 24 of 2017. Section 83(2) says that duty is not reduced by any other deduction the employer makes, or by any other law.

If your case does not fit a table

The IRD’s own instruction: if these tables do not match the tax-on-tax benefit you give an employee, write to the IRD at tpl@ird.gov.lk. Do not guess at a formula of your own.

Do this automatically in Humanised. The payroll engine calculates APIT (income tax the employer takes from pay and sends to the IRD), including tax-on-tax under Table 6. It prepares one T10 per employee. Check the tax-on-tax figure before you issue it.

This is general payroll guidance. Every case is different. For your own case, speak to a payroll practitioner or a lawyer.

Frequently asked questions

Does the employer pay tax on only part of an employee’s tax?

Table 6 covers the employer paying or reimbursing the whole tax. Partial arrangements are not covered. Ask the IRD (tpl@ird.gov.lk) for that case.

Does tax on tax apply to a bonus the same way as to monthly salary?

Yes, but under a different table. Monthly pay uses Table 6.1. A bonus or other lump sum uses Table 6.2, on the year’s cumulative EGAR.

Does an expatriate’s tax-on-tax arrangement use the same tables?

Only for a non-resident employee’s secondary job, under Table 6.3. No source gives a Table 6 method for a non-resident, non-citizen employee’s main job. Confirm with the IRD before relying on one.

Is grossing up the employer’s choice, or does the IRD set the method?

The IRD sets the method. Once an employer agrees to bear an employee’s tax, Table 6 fixes the sum. The employer does not pick its own formula.
