Ambiguity	Default
Payment type unclear	Apply the rate for the most specific matching category; if still unclear, flag

• Payment type unclear — Apply the rate for the most specific matching category; if still unclear, flag
• Resident vs non-resident recipient unconfirmed — Treat as non-resident (14%) and flag
• Rent/service-fee monthly threshold borderline — Apply WHT if aggregate exceeds LKR 100,000/month

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-1)
• 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-2)
• R-LK-WHT-3 — Sector special regimes (banking, insurance, capital markets) — Out of scope — escalate. (R-LK-WHT-3)
• R-LK-WHT-4 — VAT / SSCL withholding — Different regimes — use sri-lanka-vat / sri-lanka-sscl. (R-LK-WHT-4)

Section 3 — Tier 1 rules

3.1 Interest or discount — 10%

• Interest or discount — 10% (IRD tax chart YA 2025/26; PN/IT/2025-01; IRD Circulars SEC/2025/E/02 and SEC/2025/E/03)
• Interest/discount deduction and self-declaration relief — 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. (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%

• Dividends — 15% (Section 3.2 Dividends — 15%)

3.3 Resident rent — 10%

• Resident rent — 10% (Section 3.3 Resident rent — 10%)
• Resident rent monthly threshold — LKR 100,000 per calendar month (Section 3.3 Resident rent — 10%)

3.4 Resident service fees — 5%

• Resident service fees — 5% (Section 3.4 Resident service fees — 5%)

• Non-resident treaty cap condition — Subject to any applicable double-tax treaty cap, which requires a residence certificate. (Section 3.6 Non-residents — 14%)

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

• AIT on interest to resident company — AIT = 10% × 1,000,000 = LKR 100,000 withheld and remitted; recipient credits it. (Section 5.1 Interest paid to a resident company)

5.2 Resident rent above threshold

• AIT on 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. (Section 5.2 Resident rent above threshold)

5.3 Service fee to a non-resident consultant

• AIT on service fee to 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 5.3 Service fee to a non-resident consultant)

Section 6 — Filing and payment

• Deduction and remittance mechanics — 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).
