What falls under 998319

The CBIC Scheme of Classification defines 998319 as "Other information technology services nowhere else classified". It is a residual code, so reach for it only after ruling the specific ones out: software and web design or development is 998314, IT consulting and support is 998313, and hosting or infrastructure provisioning is 998315. Most freelance developers should be on 998314, not here.

FAQ

Do I have to print the SAC code on my invoices?

Depends on turnover: up to Rs. 5 crore, the 4-digit SAC (9983) is enough on B2B invoices; above that, 6 digits are required. Printing the full 6-digit code (998319) everywhere is simplest and never wrong.

Under Rs. 20 lakh turnover — do I need to register and charge 18%?

Below Rs. 20 lakh aggregate turnover, registration is optional for pure service providers — you invoice without GST entirely. The Rs. 10 lakh threshold applies in only four special-category states (Manipur, Mizoram, Nagaland, Tripura), not the eleven usually listed online. Once registered, 18% applies to every domestic invoice regardless of turnover.

Wrong SAC code on past invoices — how bad is it?

If the rate charged was right, it is a clerical issue — fix it going forward. A wrong code with a wrong rate is the real problem; that needs a credit note and a corrected invoice. Mismatched SACs also cause GSTR-1 Table 12 disclosure issues and can trigger ITC audit queries at the client end.

Does SAC 998319 change under GST 2.0?

No. The September 2025 rate rationalisation reshuffled the goods slabs; professional and technical services stayed at the 18% standard rate, and export zero-rating under LUT is unchanged.
