Section 2 — Required inputs and refusal catalogue

Required inputs

Payer identity & TIN; recipient legal name, TIN, and residency status; nature of payment (interest, dividend, rent, service fee, royalty); gross amount and period; any self-declaration for relief (interest); for non-residents, treaty residence certificate where treaty relief is claimed.

Refusal catalogue

R-LK-WHT-1 — APIT / PAYE on employment. Employment withholding is APIT, not this AIT regime — use sri-lanka-income-tax / sri-lanka-payroll.

R-LK-WHT-2 — Treaty rate claim without a residence certificate. Apply the statutory non-resident rate; do not apply a treaty cap without the certificate. Escalate treaty analysis.

R-LK-WHT-3 — Sector special regimes (banking, insurance, capital markets). Out of scope — escalate.

R-LK-WHT-4 — VAT / SSCL withholding. Different regimes — use sri-lanka-vat / sri-lanka-sscl.


Section 3 — Tier 1 rules

3.1 Interest or discount — 10%

Deduct 10% on interest or discount paid (raised from 5% effective 1 April 2025). A resident individual whose assessable income does not exceed the LKR 1,800,000 personal relief may self-declare to the payer to reduce/avoid the deduction — require the declaration on file. Source: IRD tax chart YA 2025/26; PN/IT/2025-01; IRD Circulars SEC/2025/E/02 and SEC/2025/E/03.

3.2 Dividends — 15%

Deduct 15% on dividends.

3.3 Resident rent — 10%

Deduct 10% on rent paid to a resident where the rent exceeds LKR 100,000 per calendar month.

3.4 Resident service fees — 5%

Deduct 5% on service fees paid to resident independent professionals where the aggregate exceeds LKR 100,000 per month.

3.5 Royalties — 14%

Deduct 14% on royalties.

3.6 Non-residents — 14%

Deduct 14% on non-resident rent, non-resident service fees, and insurance premiums (subject to any applicable double-tax treaty cap, which requires a residence certificate).


Section 4 — Tier 2

  • Credit / final tax. AIT deducted is generally creditable against the recipient's income tax. Whether a given deduction is creditable vs final depends on the recipient and payment type — VERIFY per the IRA for each stream.
  • Self-declaration mechanics (interest). The relief self-declaration is recipient-specific and time-bound; the payer must hold it before applying a reduced/zero deduction.
  • Treaty relief. Reduced rates for non-residents require a tax-residence certificate and beneficial-ownership confirmation — escalate.

Section 5 — Worked examples

5.1 Interest paid to a resident company

Bank pays LKR 1,000,000 interest → AIT = 10% × 1,000,000 = LKR 100,000 withheld and remitted; recipient credits it.

5.2 Resident rent above threshold

Company pays LKR 150,000/month rent to a resident landlord (> LKR 100,000) → AIT = 10% × 150,000 = LKR 15,000/month.

5.3 Service fee to a non-resident consultant

Payment LKR 2,000,000 to a non-resident for services → AIT = 14% × 2,000,000 = LKR 280,000 (subject to any treaty cap with a residence certificate).


Section 6 — Filing and payment

  • AIT is deducted at the time of payment and remitted to the IRD, with a withholding certificate issued to the recipient.
  • Remittance and statement due dates — VERIFY against the current IRD WHT/AIT schedule (not asserted here).

  • NEVER skip WHT on resident rent over LKR 100,000/month or resident professional service fees over LKR 100,000/month aggregate.
  • NEVER assert remittance/statement dates this skill flags as VERIFY.
  • NEVER file or instruct filing — produce a working paper for practitioner review.
