What is GST Return Filing?
GST return filing is the process of reporting:
- Sales details (Outward supplies)
- Purchase details (Inward supplies)
- Input Tax Credit (ITC)
- Tax liability
Once submitted, this information is recorded on the GST portal and becomes part of your compliance record.
Therefore, accuracy is extremely important.
Types of GST Returns You Must File
Before understanding the filing steps, it is important to know which return applies to your business.
Under Regular Scheme:
- GSTR-1 (Sales Return)
- GSTR-3B (Monthly Summary Return)
- GSTR-9 (Annual Return)
Under Composition Scheme:
- CMP-08 (Quarterly Payment Form)
- GSTR-4 (Annual Return)
Consequently, your filing process depends on your scheme selection.

Consequently, ensure adequate funds before proceeding.
Step 6: Submit & File
Finally:
- Submit return
- File using EVC or DSC
After successful filing, acknowledgment receipt is generated.

For example:
