99831 sac code for consultancy services

Group 99831 covers management and IT consulting. A freelance business consultant who advises on strategy uses 998311. A firm that advises on marketing, branding or public relations uses 998312. Consultancy in a specific technical field, such as engineering or environment, belongs in its own group (99833 or 99834) rather than 99831.

Software hsn code: 998313 or 998314

Software firms often use one of two codes. Use 998314 when you design and develop software or a website for a client. Use 998313 for IT consulting, support and maintenance contracts. Cloud hosting fits 998315. Packaged software sold on a medium is goods under 8523 at 18%, and a licence for ready made software is treated as a service. All of these are 18%, so a wrong choice between them changes the summary but not the tax.

When 998399 is the right code

998399 is the catch all for other professional, technical and business services not covered elsewhere. Use it only after checking the specific codes. Many businesses put every service under 998399, which makes their HSN summary vague. Translation, interior design consultancy and some other specialised services may fit a specific code first.

Gst on consultancy services: invoice and export

Sample invoice: IT consulting and support for the month, SAC 998313, taxable value Rs 1,20,000. CGST 9% Rs 10,800. SGST 9% Rs 10,800. Total Rs 1,41,600.

When a consultant in one state bills a client in another state, the bill carries IGST at 18%. Services to a client outside India, paid in foreign exchange and meeting the export conditions, are zero rated: you can supply under a letter of undertaking without paying tax, or pay IGST and claim a refund. A professional whose turnover crosses the registration limit of Rs 20 lakh (Rs 10 lakh in special category states) must register.
