TDS by DDOs Under GST: Deduction & Deposit Guidelines

India adopted the Goods and Services Tax framework that added TDS requirements under Section 51 of the CGST Act, 2017. The Drawing and Disbursing Officer serves as the main stakeholder required to comply with this provision.

The following blog provides an in-depth exploration of TDS by DDOs under GST through an examination of deduction regulations along with deposit standards and required compliance deadlines and the outcomes of non-compliance.

People who work in government positions alongside DDOs and professionals who manage public sector finance need complete understanding of this guidance for proper GST compliance.

What is TDS under GST?

The government employs TDS (Tax Deducted at Source) under GST to gather tax directly from sources where income or payments occur. Per Section 51 of the CGST Act, several registered entities must execute tax deductions of 2% (1% CGST plus 1% SGST or 2% IGST) from their payments made to taxable suppliers of goods or services when the supply value exceeds ₹2.5 lakhs, but excludes GST tax.

Who is a DDO (Drawing and Disbursing Officer)?

The Drawing and Disbursing Officer (DDO) service is a designation held by authorized governmental and public sector employees who control budget expenditures and payment disbursements in various entities. A key responsibility of DDOs under GST includes performing TDS deduction for their organizations, followed by TDS deposit to the relevant authorities.

Applicability of TDS Under GST for DDOs

TDS under GST applies to the following categories of entities:

A department or establishment of the Central Government or the State Government

Local authorities (e.g., municipalities, panchayats)

Governmental agencies

Public sector undertakings

Societies established by the Central or State Governments

Authorities or Boards constituted by the government act

These bodies, through their DDOs, must deduct TDS when making payments to vendors or contractors if:

The contract value exceeds ₹2.5 lakhs, and

The supply is taxable under GST.

TDS Deduction Scenarios

Deposit of TDS by DDOs

Once the tax is deducted, it must be deposited by the DDO through the prescribed electronic method.

Steps for Deposit:

Login to GST Portal as a DDO using the GSTIN assigned to your department or organization.

Generate a Challan in Form GST PMT-06 for the amount of TDS deducted.

Deposit the TDS amount through online banking, NEFT, RTGS, or over-the-counter modes using the generated challan.

Ensure payment within 10 days from the end of the month in which the deduction was made.

Due Date for Deposit

Month of Deduction	Due Date for Deposit
April	10th May
July	10th August

Important: Delays in deposit attract interest and penalties under GST laws.

Filing of TDS Returns by DDOs

The DDO must file Form GSTR-7, a monthly return for TDS deducted under GST.

GSTR-7 Return Overview

Return Name	Purpose	Frequency	Due Date
GSTR-7	To report TDS deducted under GST	Monthly	10th of next month

Key Details to Include in GSTR-7:

GSTIN of the deductor (DDO)

GSTIN of the deductee (supplier)

Contract/invoice details

Amount paid

TDS deducted and deposited

After filing GSTR-7, the deducted amount is reflected in the electronic cash ledger of the supplier, allowing them to claim credit.

Certificate of TDS: Form GSTR-7A

Upon successful filing of GSTR-7, the portal automatically generates a TDS certificate in Form GSTR-7A. This certificate must be made available to the supplier as proof of TDS deduction.

Contents of GSTR-7A:

Name and GSTIN of deductor and deductee

Invoice-wise details of the transaction

Amount of tax deducted and deposited

Date of deposit

The certificate should be issued within 5 days from the date of deposit. Failure to issue it can attract a penalty of ₹100 per day, subject to a maximum of ₹5,000.

Interest and Penalties for Non-Compliance

Non-Compliance	Consequence
Non-deduction of TDS	Interest @ 18% per annum
Late deposit of TDS	Interest @ 18% per annum
Non-filing of GSTR-7	Late fee ₹100/day (CGST) + ₹100/day (SGST), max ₹5,000
Not issuing GSTR-7A certificate	₹100/day, up to ₹5,000

Practical Challenges for DDOs

DDOs often face the following challenges in complying with TDS under GST:

Identifying applicable vendors and transactions

Delays in access to GSTINs of vendors

Technical errors during challan generation

Lack of awareness about TDS return deadlines

To overcome these, departments should organize regular training and maintain updated vendor databases with GSTINs.

Best Practices for DDOs Under GST

Verify GST Registration of suppliers before initiating payment.

Monitor contract values regularly to check TDS applicability.

Ensure timely deduction and deposit of TDS within the due date.

Maintain proper documentation, including invoices, challans, and GSTR-7A certificates.

Set reminders for return filing to avoid penalties.

TDS Adjustment and Refunds

If TDS has been deducted in excess or error:

The deductor cannot claim a refund.

Only the deductee (supplier) can claim a refund of the excess amount after filing returns.

If the TDS amount is not credited to the supplier due to incorrect GSTIN or wrong details, rectification in the GSTR-7 may be required.
