What Is This Module For?
The GST module helps you track, prepare, and manage your GST return filings — specifically GSTR-1 and GSTR-3B — as required under the Central Goods and Services Tax Act, 2017 (CGST Act).
Which Law Requires This?
- CGST Act 2017, Section 37 — Every registered taxable person must furnish details of outward supplies in GSTR-1.
- CGST Act 2017, Section 39 — Monthly return (GSTR-3B) summarising tax liability and input tax credit.
Key Filing Deadlines
- GSTR-1: 11th of the following month (turnover above ₹5 crore); quarterly for others (QRMP scheme).
- GSTR-3B: 20th of the following month for large taxpayers; staggered deadlines for others.
Late Fee: ₹50 per day (₹25 CGST + ₹25 SGST) per return, up to ₹5,000. Nil return late fee is ₹20 per day.
Step-by-Step Guide
- Go to GST in the sidebar.
- Enter your sales invoices for the month — or import them in bulk via CSV.
- The module auto-calculates your GSTR-1 data (B2B, B2C, exports, credit notes).
- Review and confirm the GSTR-1 summary.
- Download the GSTR-1 JSON for upload to the GST Portal, or export as Excel for manual entry.
- After GSTR-1 is filed, prepare GSTR-3B — enter your ITC claims and net tax payable.
- Mark each return as filed in dcomply to update your compliance status.
Common Mistakes to Avoid
- Missing the GSTR-1 deadline — Late GSTR-1 blocks your buyers from claiming ITC on their purchases from you, damaging business relationships.
- Not reconciling ITC with GSTR-2B — Always reconcile your purchase register with GSTR-2B before claiming ITC in GSTR-3B.
Frequently Asked Questions
Q: Can dcomply file GST returns directly?
A: dcomply generates the return data and JSON. Actual filing is done on the GST Portal or through a GST Suvidha Provider (GSP). Direct API filing is on our roadmap.
