Input Tax Credit (ITC) for Solar Dealers

As a GST-registered solar dealer, you can claim ITC on:

ITC is not claimable by end customers (homeowners) on solar system purchases, as it is used for personal consumption (not for taxable output supply).

Billing Best Practices for Solar Dealers

  1. Always issue GST-compliant invoices with correct HSN codes, GSTIN of buyer (if B2B), and tax breakdowns
  2. Separate equipment and service line items on your invoice for clarity
  3. File GSTR-1 and GSTR-3B on time — delays attract interest and late fees
  4. Maintain purchase invoices from suppliers for ITC claims — always buy from GST-registered distributors
  5. Check e-invoicing requirement — applicable if your annual turnover exceeds ₹5 crore (as of 2026)

GST and PM Surya Ghar Subsidy

The PM Surya Ghar subsidy is deducted from the total system cost by the government before billing the customer. Your GST invoice to the customer should be for the net amount after subsidy deduction, or alternatively, issue the invoice for the full amount and show the subsidy as a reduction — your CA should guide you on the correct treatment to avoid GST liability mismatch.
