## Compliance in Sri Lanka: Inland Revenue Amendment Act No. 11 of 2026—Withholding & VAT Updates
### Key Developments
- Under the **Amendment Act No. 11 of 2026**, Sri Lanka has activated **prosecution provisions** for failures under the Income Tax Act. Taxpayer non-compliance—late payments, incorrect withholding tax, or invalid filings—can now trigger criminal sanctions. ([ird.gov.lk](https://www.ird.gov.lk/en/sitepages/news%20and%20notices.aspx?utm_source=openai))
- There are amendments to the Value Added Tax Act, No. 14 of 2002, affecting invoice formats and VAT obligations. ([ird.gov.lk](https://www.ird.gov.lk/en/sitepages/news%20and%20notices.aspx?utm_source=openai))
- Circulars issued over August 2026 include a **Circular to Taxpayers – Calculating Quarterly Income Tax Instalments w.e.f Y/A 2026/2027** (Circular No. SEC/2026/E/06) re-revised multiple times for clarity. ([ird.gov.lk](https://www.ird.gov.lk/en/publications/sitepages/circulars.aspx?utm_source=openai))
### Implications for Withholding Tax (WHT) / Advance Income Tax (AIT)
- Agents making payments subject to AIT or WHT must **ensure timely withholding**, proper filing, and remittance. With prosecution now a possibility, the margin for error has narrowed.
- Monthly/quarterly schedules for payment remain fixed: payments withheld in a month must be paid by **15th of next month**. Missed deadlines now come with added legal risk. ([ird.gov.lk](https://www.ird.gov.lk/en/sitepages/news%20and%20notices.aspx?utm_source=openai))
### VAT and Invoice Compliance
- The revised VAT law affects how VAT invoices must be formatted and how transactions should be reported. Registered persons should review updated invoice and WEB API integration requirements. ([ird.gov.lk](https://www.ird.gov.lk/en/sitepages/default.aspx?sf112737983=1&utm_source=openai))
- For supplies made on non-foreign exchange (NFE) basis to exporters especially, special reporting obligations via schedule templates have been updated. ([ird.gov.lk](https://www.ird.gov.lk/en/sitepages/default.aspx?utm_source=openai))
### Example Scenarios & Risks
| Your Role | What You Should Do | Risks if Non-Compliant |
|---|---|---|
| Bank withholding interest payments | Deduct AIT/WHT correctly, deposit by due date (15th of next month); file monthly statement on time | Penalties, possible prosecution under Amendment Act; no relief for ignorance |
| VAT registered exporter using ERP | Ensure invoices meet new format; integrate NFE supplies via WEB API as required; reflect export-related supplies accurately | Delays in VAT refunds; audits or assessments on exports misclassified |
| Retailer failing to issue proper VAT invoice | Upgrade invoice templates; train staff; sample checks to avoid errors | Fines, liability by principals; risk of losing registered status |
### Best Practices for Compliance
- **Review and update internal processes and checklists**: Who reviews invoices? Who files WHT statements? Ensure owners/directors own compliance.
- **Vendor due diligence**: If paying vendors or service providers, make sure their tax status is correct; take declarations to avoid joint liability.
- **Leverage technology**: Use invoice-generation tools, ERP or accounting software that allow format updates and integration with VAT systems.
- **Stay informed**: Read circulars such as No. SEC/2026/E/06; subscribe to IRD’s notices and FAQs.
**Bottom line**: The Amendment Act No. 11 of 2026 in Sri Lanka raises the stakes on tax compliance—most notably withholding, VAT, and invoice formats. Strengthening processes now can avoid legal exposure in the near term.
