Kerala Commercial Tax Payment Online: GST, KITIS & e-Treasury

Use the correct official portal for the tax you need to pay. Current GST liabilities are paid through the GST Portal, while Kerala legacy taxes such as KGST, KVAT and CST are handled through KITIS. Kerala e-Treasury is used for supported State Government receipts and tax payments.

Which Kerala Tax Payment Portal Should You Use?

The older Kerala Commercial Taxes Department iCOMITRAX links are no longer the correct starting point for most taxpayers. Kerala's tax-payment systems now depend on the type of tax or liability involved.

GST / SGST / CGST / IGST:
Use the national GST Portal for GST challans, electronic cash ledger deposits and GST liability payments.
KGST, KVAT and CST legacy taxes:
Use KITIS - Kerala Indirect Tax Information System. Kerala shifted return filing and payment for these legacy Acts to KITIS from 1 August 2024.
State Government receipts / specified legacy payments:
Use the official Kerala e-Treasury where the relevant department, Act or payment head is available.
Important: Do not use an old iCOMITRAX or Commercial Taxes Department login link from an archived guide. Start from the current Kerala State GST Department, KITIS, GST Portal or e-Treasury as applicable.

Current Law: GST and Kerala Legacy Commercial Taxes

Current GST framework: Kerala State Goods and Services Tax Act, 2017, Central Goods and Services Tax Act, 2017 and Integrated Goods and Services Tax Act, 2017.
Legacy Acts still relevant for older liabilities: Kerala General Sales Tax Act, 1963; Kerala Value Added Tax Act, 2003; and Central Sales Tax Act, 1956.

GST replaced the earlier VAT-based indirect tax system for most supplies from 1 July 2017. However, liabilities, returns, assessments, arrears and specified transactions under older Kerala commercial tax laws can continue to require action under those legacy statutes.

Kerala introduced the Kerala Indirect Tax Information System (KITIS) for electronic filing and payment under the KGST, KVAT and CST laws. The State GST Department's official KITIS guidance states that filing of returns and payments under those Acts moved to KITIS from 1 August 2024.
