Business documents in Sri Lanka

Paperwork in Sri Lanka is shaped by three institutions more than any other: the Inland Revenue Department (IRD), which issues every business its Taxpayer Identification Number (TIN) and polices VAT invoices; the Department of the Registrar of Companies (ROC), which runs incorporation and annual filings online through eROC; and Sri Lanka Customs, which processes every import and export declaration. 2026 has been an unusually busy year for all three, with a prescribed tax invoice format, beneficial ownership filings and paperless customs declarations all becoming mandatory.

It is written for private limited companies, sole proprietors, partnerships, exporters, SMEs selling to larger corporates, and freelancers invoicing local or overseas clients — covering the tax invoices, quotations, appointment letters, EPF records and shipping documents you actually issue.

Facts were checked against IRD notices, Gazette specifications, ROC guidance, the EPF and ETF boards and Sri Lanka Customs in November 2026. Tax rules changed several times this year, so confirm anything material with the IRD or your tax adviser before relying on it.

Incorporating through eROC and the Companies Act No. 7 of 2007

Most growing businesses in Sri Lanka operate as a private limited company — “(Private) Limited” or “(Pvt) Ltd” — under the Companies Act No. 7 of 2007. Public companies (PLC), companies limited by guarantee, unlimited companies and overseas companies with a place of business in Sri Lanka are also registered by the Registrar of Companies. Sole proprietorships and partnerships are not ROC entities; they register a business name with the Divisional Secretariat or the relevant provincial authority instead.

Incorporation is handled online through eROC. You reserve a name, then file Form 1 (application for registration), Form 18 (consent and certificate of each initial director), Form 19 (consent of the initial company secretary) and the Articles of Association, which can follow the model in the Act or be drafted for the company. Signed forms are scanned to PDF and uploaded, and the certificate of incorporation is downloaded from the eROC dashboard with a QR code for verification.

Beneficial ownership is the big change of 2026. The Companies (Amendment) Act No. 12 of 2025 came into operation on 30 March 2026, together with the Companies (Beneficial Ownership) Regulations No. 01 of 2026. New companies file Form BO 1 at incorporation, every company appoints an authorised person (Form BO 5), share issues and transfers carry BO 2 and BO 3 notices, and beneficial ownership details accompany the annual return (Form 15) as Form BO 4. Existing companies had transitional reporting duties on Form BO 7.

After incorporation, a company needs its own TIN, share certificates, a bank account and EPF/ETF employer numbers before it pays staff. Board and shareholder resolutions are the everyday paper trail for appointing directors, opening accounts and issuing shares.

  • Form 1 — application for registration of a company
  • Form 18 / Form 19 — consents of initial directors and company secretary
  • Form 15 — annual return, now filed with Form BO 4 beneficial ownership details
  • Forms BO 1–BO 7 — beneficial ownership notices under the 2026 regulations

VAT, SSCL and the prescribed tax invoice format

VAT is charged under the Value Added Tax Act No. 14 of 2002 at a standard rate of 18%. A business must register when taxable supplies exceed Rs. 15 million in a quarter or Rs. 60 million over twelve months. The 2026 Budget proposed cutting this to Rs. 36 million from 1 July 2026, but the government told Parliament in June 2026 that the cut would not be implemented and the IRD confirmed the existing thresholds remain. The VAT (Amendment) Act No. 14 of 2026 separately moved financial services VAT to 20.5% from 1 July 2026 and brought non-resident suppliers of electronic services into the VAT net from the same date.

The Social Security Contribution Levy (SSCL) is a separate 2.5% levy on liable turnover under the Social Security Contribution Levy Act No. 25 of 2022. The SSCL (Amendment) Act No. 10 of 2026 legislated a lower registration threshold from 1 July 2026, yet the government later announced it would keep the existing Rs. 60 million threshold for both VAT and SSCL “at this stage”. Because the two signals conflict, confirm your SSCL position with the IRD before deciding you are below the line.

The tax invoice itself is now prescribed. The Commissioner General first specified a format in Gazette Extraordinary No. 2463/05 (November 2025), replaced it with a revised format in Gazette No. 2481/22 (27 March 2026), and postponed the mandatory date to 1 October 2026 through Gazette No. 2500/106. Every VAT-registered supplier issuing a tax invoice must now follow it. Businesses approved by the Commissioner General to link their ERP to the IRD’s RAMIS system through a Web API may be relieved of part of the serial-number prefix; check the conditions with the IRD.

Two details catch people out: dates must be in MM/DD/YYYY order, and the invoice may list only goods or services that attract VAT — exempt items go on a separate document. Older templates that show only a “VAT Reg. No.”, round off cents or omit the buyer’s TIN need updating.

Quotations, purchase orders and the rest of the sales trail

Corporate buyers and state institutions in Sri Lanka usually want written quotations — often three to compare — before raising a purchase order. A good quotation states your registered name and TIN, a quotation number, validity period, whether prices include VAT and SSCL, and delivery and payment terms.

The buyer then issues a purchase order, goods travel with a delivery or dispatch note signed by the receiving stores, and the tax invoice quotes the PO number. Advances are requested on a proforma invoice, which must never carry the “TAX INVOICE” title.

Cash and cheque collections are acknowledged with numbered receipts. Returns and price corrections are handled with credit and debit notes that cite the original invoice, keeping your VAT return and the buyer’s input-tax claim aligned.

  • Quotation — validity, VAT treatment and delivery terms spelled out
  • Purchase order — the buyer’s commitment, quoted on your invoice
  • Delivery or dispatch note — signed by the buyer’s stores on receipt
  • Proforma invoice — for advances and import payments, not a tax document
  • Receipt, credit note and debit note — each linked to the original invoice

Appointment letters, EPF and ETF

Employment in Sri Lanka usually starts with a letter of appointment that sets out the job title, start date, probation period, salary and allowances, working hours, leave and notice terms. Shop and office staff, factory workers and workers in wages-board trades are covered by different statutes, so the letter should reflect the law that applies to your sector. Monthly salary slips showing gross pay, deductions and the EPF contribution are standard practice and help when staff apply for loans or visas.

Every employer must register with the Employees’ Provident Fund, which is administered by the Commissioner of Labour with the Central Bank of Sri Lanka as custodian. The minimum contribution is 20% of an employee’s total monthly earnings: at least 8% deducted from the employee and at least 12% paid by the employer. Contributions for a month are due by the last working day of the following month, using Form C or e-C forms; employers with 50 or more staff must submit their returns electronically. Late payments attract surcharges that grow with the delay.

Employers also pay 3% of monthly earnings to the Employees’ Trust Fund, a separate board. Gratuity under the Payment of Gratuity Act No. 12 of 1983 becomes payable to qualifying employees on termination after the statutory period of continuous service, so your HR records need accurate start dates.

When an employee leaves, employers are expected to issue a service letter confirming dates of employment and designation; banks and embassies often ask for a salary certificate too.

Commercial agreements, stamp duty and electronic signatures

Service agreements, distribution and agency contracts, NDAs and MOUs are typically drafted in English, governed by Sri Lankan law and signed by authorised signatories backed by a board resolution.

Some instruments, such as leases and mortgages, attract stamp duty, and deeds dealing with land are executed before a notary public. Ordinary NDAs and service agreements generally need neither, but check before signing anything property-linked.

The Electronic Transactions Act No. 19 of 2006 gives legal recognition to electronic documents and electronic signatures, so a contract signed electronically is generally enforceable. Exceptions exist for documents such as wills and land instruments, and some counterparties still insist on wet-ink originals with the company stamp.

Trading through Sri Lanka Customs: CusDec, ASYCUDA and export paperwork

Every import and export is declared to Sri Lanka Customs on a Customs Declaration (CusDec) lodged through the ASYCUDA system, usually by a licensed customs house agent. Since 1 October 2026 Customs requires paperless CusDec submission with digital signatures and no longer accepts manual counter lodgement, so your supporting documents need to be clean and consistent in electronic form.

A typical export or import file includes the commercial invoice (with HS codes, Incoterms and currency), packing list, bill of lading or air waybill, and any licences or permits from other agencies. Exporters who rely on preferential tariffs under trade agreements also need the appropriate certificate of origin, issued through the designated authority for that agreement.

A National Single Window is still being built, so permits from other agencies may come through separate systems. Match descriptions, quantities and values exactly — discrepancies between the CusDec and the commercial invoice are a common cause of delay.

Record keeping, language and currency

Under the tax invoice specification, both supplier and purchaser must keep invoice records for at least five years from the end of the relevant taxable period, in their original form with integrity and accessibility preserved. Many businesses keep records longer for audits and EPF inspections.

Business documents in Sri Lanka are almost always prepared in English, although Sinhala and Tamil are official languages and some government correspondence uses them. Tax invoices must state the value of supply in Sri Lankan rupees. If you price an export or a contract in USD, show the LKR equivalent and the exchange rate used wherever a local tax figure appears.

Frequently asked questions about business documents in Sri Lanka

What is the new tax invoice format in Sri Lanka?
It is the format prescribed by the Commissioner General of Inland Revenue in Gazette Extraordinary No. 2481/22, mandatory from 1 October 2026 after Gazette No. 2500/106 postponed it. The invoice must be titled “TAX INVOICE” and show both parties’ TINs, names and addresses, a serial number in YYMMM_QQQQ_XXXXX form, the invoice date and date of supply, a description and quantity, and the value excluding VAT, VAT and total in LKR.
Do I put the VAT number or the TIN on a Sri Lankan tax invoice?
The 2026 format asks for the 9-digit TIN of both the supplier and the purchaser. Update templates that still show only a “VAT Reg. No.” field, and collect the buyer’s TIN before you issue the invoice.
What is the VAT registration threshold in Sri Lanka in 2026?
Registration is required when taxable supplies exceed Rs. 15 million in a quarter or Rs. 60 million over twelve months. A cut to Rs. 36 million was proposed for 1 July 2026 but the government decided in June 2026 not to implement it, and the IRD confirmed the existing thresholds remain.
Is SSCL still charged in Sri Lanka?
Yes. The Social Security Contribution Levy continues at 2.5% on liable turnover, although financial services taxed at the 20.5% VAT rate are exempt from it. Threshold rules changed on paper in 2026 and the government then said it would keep the existing threshold, so confirm your position with the IRD.
How much is EPF and ETF in Sri Lanka?
EPF is at least 20% of total monthly earnings — at least 8% from the employee and 12% from the employer. The employer also pays 3% to the Employees’ Trust Fund. EPF for a month is due by the last working day of the following month.
What forms do I need to register a private limited company?
Through eROC you reserve a name and file Form 1, Form 18 for each initial director, Form 19 for the company secretary and the Articles of Association. Since 30 March 2026 you also file Form BO 1 with beneficial ownership details.
Does a proforma invoice count as a tax invoice in Sri Lanka?
No. A proforma is a request for payment or an offer, so it should not be titled “TAX INVOICE” or be used to claim input VAT. Issue the tax invoice in the prescribed format once the supply is made.
How long should I keep tax invoices in Sri Lanka?
Both supplier and purchaser must keep tax invoice records for at least five years from the end of the taxable period, in original form. Many businesses keep them longer for audits and company law purposes.
Is an electronically signed contract valid in Sri Lanka?
Generally yes — the Electronic Transactions Act No. 19 of 2006 recognises electronic documents and signatures. Documents such as land deeds and wills are excluded and still need traditional execution, often before a notary.
Can I still submit a CusDec on paper?
No. From 1 October 2026 Sri Lanka Customs requires paperless CusDec submission with digital signatures and no longer accepts manual counter submissions. Your customs house agent lodges the declaration through ASYCUDA.
