Sri Lanka Tax Guide

VAT and SSCL in Sri Lanka Explained Simply

A plain-English guide to Value Added Tax and Social Security Contribution Levy in Sri Lanka, including what they mean, how they are estimated, registration thresholds, and why VAT and SSCL are not always calculated on the same amount.

Last updated: May 2026

This guide uses publicly available Sri Lankan tax, IRD, Customs, Provincial Revenue, or government information available at the time of writing. Tax rates, thresholds, forms, exemptions, valuation treatment, import rules, and filing requirements can change. Always confirm final amounts with the relevant authority or a qualified professional before making financial, tax, legal, property, import, or business decisions.

What is VAT?

VAT means Value Added Tax. In simple terms, it is a tax charged on taxable goods and services. A VAT-registered business usually collects VAT from customers and may claim input VAT paid on eligible business purchases.

VAT is usually important for businesses because it affects selling price, invoicing, cash flow, customer pricing, and tax return filing. For customers, VAT is usually seen as an added amount on top of the price of taxable goods or services.

What is SSCL?

SSCL means Social Security Contribution Levy. It is a separate levy from VAT. Unlike VAT, SSCL is generally calculated on liable turnover according to the category of business.

This is why VAT and SSCL can be confusing. VAT may be calculated on taxable supply and reduced by claimable input VAT, while SSCL is calculated on liable turnover using the applicable SSCL percentage and business category rules.

VAT Usually added to taxable sales and reduced by claimable input VAT.

SSCL Calculated on liable turnover depending on the business category.

Both matter A business may need to consider VAT, SSCL, income tax, and filing obligations separately.

VAT rate in Sri Lanka

The standard VAT rate used in this guide and calculator is 18%. This means that if a taxable sale before VAT is LKR 100,000, the VAT amount at 18% would be LKR 18,000.

Taxable sale before VAT	VAT rate	VAT amount	Customer price if VAT is added
LKR 100,000	18%	LKR 18,000	LKR 118,000
LKR 1,000,000	18%	LKR 180,000	LKR 1,180,000
LKR 10,000,000	18%	LKR 1,800,000	LKR 11,800,000

Some supplies may be zero-rated, exempt, or treated differently. That is why a simple calculator should be used as a planning tool only.

Input VAT and VAT payable

A VAT-registered business may collect VAT from customers and may also pay VAT on business purchases. The VAT payable estimate is often calculated by subtracting claimable input VAT from VAT collected.

Step	Simple formula	Example
VAT collected	Taxable sales × 18%	LKR 20,000,000 × 18% = LKR 3,600,000
Input VAT claimed	VAT paid on eligible business purchases	LKR 1,000,000
Estimated VAT payable	VAT collected − input VAT claimed	LKR 3,600,000 − LKR 1,000,000 = LKR 2,600,000

Not every VAT paid on purchases is automatically claimable. Actual treatment can depend on VAT registration, invoice requirements, business use, exemptions, and IRD rules.

VAT registration threshold

A business may need to consider VAT registration if its taxable supply exceeds the relevant threshold. For goods or services other than financial services, the basic threshold shown by IRD is LKR 15 million per quarter or LKR 60 million for a 12-month period.

Period	Basic VAT registration threshold
Quarter	Exceeds LKR 15,000,000
12 months	Exceeds LKR 60,000,000

Importers, exporters, financial services, voluntary registration, and special business types may have different requirements or additional registration rules.

SSCL rate and liable turnover

The standard SSCL rate used in this guide and calculator is 2.5%. However, the amount subject to SSCL is not always the full turnover. The liable turnover percentage depends on the category of business.

Business category	Liable turnover basis used in the calculator	Plain-English meaning
Importation	100% of turnover	SSCL estimate uses the full turnover entered.
Manufacturing	85% of turnover	SSCL estimate uses 85% of the turnover entered.
Services	100% of turnover	SSCL estimate uses the full turnover entered.
Wholesale / retail	50% of turnover	SSCL estimate uses 50% of the turnover entered.
Registered distributor	25% of turnover	SSCL estimate uses 25% of the turnover entered.

Because of this, two businesses with the same sales may have different SSCL estimates if they fall under different business categories.

SSCL registration threshold

For many taxable persons, the basic SSCL registration threshold is similar to the VAT threshold: turnover exceeding or likely to exceed LKR 15 million for a quarter, or LKR 60 million for a period of four consecutive quarters.

Period	Basic SSCL registration threshold
Quarter	Exceeds or likely to exceed LKR 15,000,000
Four consecutive quarters	Exceeds or likely to exceed LKR 60,000,000

This threshold check is only a basic guide. Exemptions, special categories, and industry-specific treatments can change the actual position.

Example: service business with LKR 20 million quarterly turnover

Here is a simple example using a service business with taxable sales before VAT of LKR 20 million for a quarter and claimable input VAT of LKR 1 million.

Item	Calculation	Amount
Turnover before VAT	Amount entered	LKR 20,000,000
VAT collected	20,000,000 × 18%	LKR 3,600,000
Input VAT claimed	Amount entered	LKR 1,000,000
Estimated VAT payable	3,600,000 − 1,000,000	LKR 2,600,000
SSCL liable turnover	Service business = 100% of turnover	LKR 20,000,000
Estimated SSCL payable	20,000,000 × 2.5%	LKR 500,000
Total VAT + SSCL estimate	2,600,000 + 500,000	LKR 3,100,000

Why VAT and SSCL can feel confusing

VAT and SSCL often appear together, but they are not the same tax. VAT is usually connected to output VAT collected and input VAT claimed. SSCL is connected to liable turnover and business category.

VAT can be affected by input VAT claims.
SSCL can be affected by the liable turnover percentage.
VAT and SSCL may have separate filing and payment requirements.
Some goods, services, or industries may have special rules or exemptions.
Registration thresholds do not always mean the same thing as final tax payable.

Before charging customers, filing returns, or making business decisions, confirm the final treatment with IRD, an accountant, a tax consultant, or another qualified professional.
