Form GSTR-7 is the monthly GST TDS return due by the 10th. Learn who files, the process, late fees and how to avoid the most common deductor mistakes.
Form GSTR-7 is the monthly return that every person liable to deduct Tax Deducted at Source (TDS) under GST must file. With the GST framework continuing to mature post Union Budget 2026, the compliance burden on government bodies, PSUs and notified deductors has only sharpened. The GSTN portal has issued repeated advisories urging deductors to file Form GSTR-7 before the 10th of every succeeding month to avoid late fees, interest and reconciliation issues for their vendors.
Who is required to file GSTR-7
Section 51 of the CGST Act, 2017 mandates TDS deduction at 2% (1% CGST + 1% SGST or 2% IGST) on payments to suppliers where the taxable contract value exceeds ₹2.5 lakh. The following persons must register as TDS deductors and file GSTR-7 monthly:
- A department or establishment of the Central or State Government
- Local authorities and governmental agencies
- Public sector undertakings notified by the Government
- Society established by the Central or State Government or a Local Authority
- Authorities, boards or any other body set up by Parliament or State Legislature with 51% or more government participation
Due date and consequences of delay
GSTR-7 must be filed by the 10th of the month following the month of deduction. Filing beyond the due date attracts a late fee of ₹100 per day under CGST and an equal amount under SGST, capped at ₹5,000 per Act. In addition, interest at 18% per annum is payable from the date the tax was deductible until the date of payment to the Government.
Delay also impacts the deductee. The TDS credit reflects in the deductee's Electronic Cash Ledger only after GSTR-7 is filed and GSTR-7A (the TDS certificate) is generated. Vendors who depend on this credit for their own GST liability are directly hurt by late filing.
Step-by-step filing process on the GST portal
- Log in to the GST portal and navigate to Services > Returns > Returns Dashboard.
- Select the financial year and tax period (month) and click Prepare Online for GSTR-7.
- Enter GSTIN of each deductee, gross payment, value on which TDS is deducted and the tax amount.
- Use Table 4 for amendments to past period entries, if any.
- Preview the draft, pay the tax through the Electronic Cash Ledger and file using DSC or EVC.
Common errors deductors must avoid
- Wrong GSTIN of the deductee — leads to credit not flowing to the correct vendor
- Treating exempt or non-taxable supplies as TDS deductible
- Ignoring the ₹2.5 lakh contract value threshold
- Not deducting TDS where supplier and place of supply are in different States but registration is in a third State
- Missing the cap on aggregate late fees per return
Best practices for monthly compliance
Beyond statutory filing, deductors should build operational guardrails into their workflow. Treating GSTR-7 as a four-week running activity — not a 10th-of-the-month scramble — reduces errors and protects the entire vendor base. The following practices have proven effective across PSUs and government departments managing thousands of monthly vendor payments.
- Maintain a master vendor database with verified GSTINs, contact details and bank accounts
- Reconcile TDS deducted in the accounting system with the GST portal challan ledger weekly
- Generate Form GSTR-7A immediately after filing and share with vendors as proof of credit
- Use a maker-checker workflow for any payment above an internal materiality threshold
- Run an annual review of vendor classification — composition dealers do not require TDS deduction
Such discipline pays dividends not only in compliance scoring but also in vendor satisfaction. When suppliers know that their TDS credit will flow predictably, payment cycles improve and the deductor builds a reputation for operational reliability that supports future tendering and procurement.
Interest, penalty and prosecution exposure
Persistent default in filing GSTR-7 invites scrutiny beyond the routine late fee. The CGST Act provides for interest at 18% per annum on the TDS amount, a penalty of up to 25% of the tax under Section 122 for habitual default, and even prosecution in extreme cases. PSU and government finance teams have a fiduciary duty to ensure that public funds withheld as tax are deposited promptly, and audit observations on GSTR-7 default frequently feature in CAG reports.
- 18% interest from the date tax was deductible until the date of payment
- Penalty up to ₹25,000 or 25% of the tax under Section 122 for habitual default
- Reputational impact in audit reports and parliamentary scrutiny
- Vendor litigation risk where ITC credit is delayed materially
- Personal liability of the deductor-in-charge in severe cases
Conclusion
Filing GSTR-7 by the 10th of every month is a small discipline that protects both the deductor and the vendor ecosystem. With the GSTN portal continuously tightening reconciliation between GSTR-7, GSTR-2B and the cash ledger, deductors should put in place a fixed monthly calendar and a maker-checker review before submission to stay fully compliant under the FY 2026-27 regime.
