Rates shown here are as published in GST rates on services, Notification 11/2017-Central Tax (Rate) as amended up to Notification 15/2025-Central Tax (Rate) and are reproduced for reference. The GST Council revises rates through notifications, including the rate rationalisation effective 22.09.2025 that withdrew the 12% and 28% slabs for most services and introduced a 40% rate for a short list of them. Always verify the current rate and the conditions attached to it on the CBIC GST rates page or the CBIC tax information portal before invoicing or filing. Rates exclude any applicable cess. IncorpX provides assistance for GST registration and return filing if you need help.
Some supplies under this heading carry no GST at all. An exemption removes the charge rather than setting a rate, so it overrides the schedule where it applies.

SAC 99546 questions
What does SAC group 99546 cover?
Group 99546 of the SAC classification covers installation services. It sits under heading 9954 and holds 8 six-digit service codes. The GST rate is set at the heading, so services here are taxed under the entries written against 9954, normally at 1.5% to 18%.
What is the GST rate for SAC 99546?
The rate schedule is written against heading 9954, not against the 5-digit group, so the rate for a service here comes from that heading's entries. Entries that can reach this group run from 12% to 18%, so read the descriptions to see which one matches your supply. Verify the current rate on the CBIC portal before invoicing.
Which SAC code should I quote from this group?
Pick the 6-digit code whose official description covers what you actually supply, not the closest sounding name. Every code in this group is listed below with its own page, where the official annexure text and the rate entries are set out in full.
Can I quote the 5-digit group code on an invoice?
No. Invoices and the GSTR-1 summary take either the 4-digit heading (9954) or the full 6-digit code, depending on your aggregate turnover. The 5-digit group is a level of the classification, not a reporting format.
