GST returns can be prepared and filed electronically through the GST Portal.
A simplified workflow is:
Step 1: Collect records
Gather sales and purchase invoices for the relevant period.
Step 2: Review sales
Check invoice numbers, GSTINs, taxable values and GST amounts.
Step 3: Reconcile purchases
Compare purchase records with available GST data and identify missing or incorrect invoices.
Step 4: Prepare applicable returns
Prepare the required GST returns based on the taxpayer's filing requirement.
Step 5: Review tax liability
Verify output tax, eligible ITC and resulting tax payable.
Step 6: File
After reviewing the return, submit and complete the applicable filing process.
Step 7: Preserve records
Keep copies of invoices, workings, returns and payment information for future reference.
The GST Portal provides official return-filing functionality and guidance for forms such as GSTR-9.
