A car accessories shop sells seat covers, floor mats, music systems, lights, sensors and body kits that fall under many HSN headings, most of them at 18% after the September 2025 changes. The invoice must give each item its own HSN, such as 8708 for vehicle parts and accessories, 8512 for lighting and sensors, 8527 for car stereos and 9401 for vehicle seats, show the car model it is fitted on, and list fitting or wiring labour as a separate service under SAC 998714.

Extra fields a car accessories shop invoice needs
Car make and model fitted
Most accessories are model specific. The model on the bill confirms fitment and protects the shop if the customer later claims the wrong item was supplied.
Vehicle registration number
Customers often fit accessories on more than one car. The registration number links the work to a vehicle, which matters for warranty and insurance claims.
HSN for each accessory
Accessories cross many headings. An item-wise HSN keeps the GSTR-1 HSN summary right, even when most rates are 18%.
Brand and warranty period
Music systems, cameras and lights carry warranties. Brand and warranty period on the invoice speed up warranty claims with distributors.
Fitting and wiring labour
Installation is a service. Listing labour separately at 18% under 998714 avoids hiding service income inside goods lines.
Serial numbers for electronics
Infotainment units and dash cams have serial numbers. Recording them deters theft and helps trace stock.
Return and exchange terms
Model-specific accessories are often returned when they do not fit. Printing the return window and condition on the bill sets expectations and supports a proper credit note when a return is accepted within the agreed period.
Standard GST invoice fields
Rule 46 of the CGST Rules applies to every tax invoice, including this one:
✓Supplier name, address and GSTIN
✓Consecutive invoice number (max 16 characters, unique for the year)
Notification 9/2025-CT(Rate) places parts and accessories of motor vehicles under heading 8708, electrical lighting and signalling equipment and wipers of a kind used for motor vehicles under 8512, radio-broadcast receivers under 8527, loudspeakers under 8518 and seats under 9401 in the 18% schedule. The 56th Council also listed seats of a kind used for motor vehicles among items moved from 28% to 18%. Shops should clear out old 28% rates from their software.
Classification of common accessories
Seat covers made of textile may be classified under textile headings rather than 8708 depending on their nature, and rubber floor mats under rubber articles. Mirrors fall under glass mirrors. The rate for these is generally 18%, but the HSN must still match the goods. Use the HSN printed on the supplier's invoice as a starting point, and keep the classification consistent across purchases and sales.
Accessories fitted at a dealership
When a car dealer sells an accessory kit with a new car, the kit is a separate supply and should not be taxed at the car's rate. Independent accessory shops face the reverse question when they fit accessories with labour: a composite supply of goods and installation may be taxed at the rate of the principal supply, but separate lines with separate prices are the clearer route, especially with both at 18%.
Warranty replacements
Replacing a faulty unit under the manufacturer's warranty at no charge is not a fresh supply by the shop to the customer. The shop returns the faulty unit to the distributor and receives a replacement. Record the replacement with a delivery challan or zero-value document, so stock records match and no tax is wrongly charged to the customer.
Online and marketplace sales
Accessory shops increasingly sell through e-commerce marketplaces. The marketplace collects TCS under GST on the net value of taxable supplies and reports it, and the seller claims that TCS as credit. Sellers must register even below the usual threshold when selling goods through an operator that collects TCS, subject to the exemptions notified for small sellers. The invoice to the online buyer must carry the same HSN and rate as a counter sale, and the order number should be printed so returns can be matched.
Common billing mistakes
✕Billing all accessories under one HSN like 8708 regardless of what they are.
✕Leaving fitting labour inside the product price without a separate service line.
✕Still charging 28% on seats or lighting kits after 22 September 2025.
✕Not recording serial numbers of electronic units sold and fitted.
Car Accessories Shop GST invoice: FAQ
What is the GST on car accessories?
+
Most car accessories, including parts and accessories under 8708, lighting and sensors under 8512, stereos under 8527 and seats under 9401, attract 18% from 22 September 2025.
Should fitting charges be shown separately?
+
Yes. Fitting and wiring labour is a service under SAC 998714 at 18%. Showing it separately keeps your goods and services reporting accurate.
Is a free accessory with a purchase taxable?
+
If the free item is given as part of a single price for the bundle, it is not separately taxed, but it should appear on the invoice as a zero-value line so stock records reconcile.
Can an accessories shop use the composition scheme?
+
Traders within the composition turnover limit can opt for it, but a shop that also earns significant fitting labour must check the limit on service turnover allowed under composition for goods suppliers.
Do dash cams attract 18% GST?
+
Dash cams are recording apparatus and are classified under their own electronics heading, generally at 18%. Check the HSN given by your supplier and use it consistently.
