For B2B service invoices, the tax type is determined by the client's state:
Example
A Delhi-based event management company (₹5 lakh contract) working for a Mumbai corporate client. Place of supply = Maharashtra. Tax = IGST 18% = ₹90,000. Invoice total = ₹5,90,000.
A service GST invoice is a tax invoice issued by a service provider. It uses SAC code instead of HSN, does not require quantity/unit fields, and must be issued within 30 days of service.
Most professional and business services attract 18% GST. Exceptions: restaurant (5%), transport (5%), healthcare and education (exempt).
For B2B, place of supply is the registered recipient's state. For B2C, it is the supplier's state. This determines whether CGST+SGST or IGST applies.
Yes. You can list multiple services on one invoice. Each line item should have its own SAC code and GST rate. The GST is summed at the bottom.
Within 30 days of the service completion date. For banking and insurance services, 45 days. For continuous supply (monthly retainer), on or before each payment due date.
Charging CGST + SGST for inter-state services
If your client is in a different state, you must charge IGST (18%) — not CGST + SGST. Charging the wrong combination forces both parties to file corrections.
Not including a SAC code on service invoices
Every GST invoice for services must include the correct SAC (Service Accounting Code). Missing SAC codes are flagged during GST audits and can delay ITC for your client.
Not registering when turnover crosses ₹20 lakh
Service providers must register once annual turnover exceeds ₹20 lakh (₹10 lakh in special category states). Operating above this limit without registration attracts 18% penalty on the unpaid tax.
Issuing a single invoice for multiple months of service
For ongoing services, you must invoice at least monthly. Bundling multiple months into one invoice creates liability mismatches in GSTR-1 and can result in late-filing interest charges.
Missing mandatory fields — invoice number, date, or GSTIN
A GST invoice missing any of the 16 mandatory fields under Section 31 of the CGST Act is legally invalid. Your client cannot claim ITC on an invalid invoice.
