Imagine a government department hiring a contractor to do maintenance work in a power plant. The total value of the work is ₹75 lakh. Before paying the contractor, the department deducts a small part of the GST and deposits it directly with the government. This process is called GST TDS (Tax Deducted at Source).
GST TDS mainly applies to government departments and some public organizations.
The idea is simple: a part of the tax is collected at the time of payment, so the government receives the tax on time. Now, let us understand how GST TDS works in simple terms.
Key Takeaways
- GST TDS means certain government bodies deduct 2% tax while paying suppliers for contracts above ₹2.5 lakh.
- The deduction is calculated only on the taxable value, not on GST shown in the invoice.
- Most deductors include government departments, PSUs, and government-controlled organisations.
- The deducted tax must be deposited with the government and reported through Form GSTR-7.
- The supplier receives the deducted amount as credit in their Electronic Cash Ledger on the GST portal.
What is TDS Under GST?
Tax Deducted at Source (TDS) under GST means that a specified buyer deducts a small percentage of GST while making payment to a supplier and deposits that amount with the GST department.
Let me explain how this usually happens in practice.
Suppose a government department purchases services from a contractor. When the department releases payment, it does not transfer the entire amount to the supplier. Instead, it deducts a small portion of GST and deposits it with the government.
Later, the supplier can see this deducted amount in their GST electronic cash ledger and use it while paying their GST liability.
So in simple words:
- The buyer deducts GST
- The government receives it immediately
- The supplier gets credit of that amount
This system improves tax transparency and ensures timely tax collection.
Who Is Required to Deduct GST TDS?
This rule mainly applies to government-related organisations and certain bodies that are largely controlled by the government.
In India, GST TDS is typically deducted by:
- Central Government departments
- State Government departments
- Local authorities (for example, municipal corporations)
- Government agencies
- Public sector undertakings (PSUs)
- Government-controlled boards, authorities, or bodies where the government holds 51% or more ownership or control
- Societies created by government or local authorities
From practical experience, most suppliers encounter GST TDS when they work with government departments or PSUs.
Private companies generally do not fall under this rule.
When GST TDS Must Be Deducted
GST TDS applies only when the value of taxable supply under a contract crosses a certain limit.
In simple terms, if the value of taxable goods or services in a contract is more than ₹2,50,000 (excluding GST), TDS must be deducted by the specified buyer.
The key point beginners often miss is this: The limit of ₹2.5 lakh is calculated only on the taxable value, not including GST.
Example
A contractor supplies computers to a government department.
| Particular | Amount |
|---|---|
| Value of computers | ₹3,00,000 |
| GST | ₹54,000 |
| Invoice total | ₹3,54,000 |
Here the taxable value is ₹3,00,000, which is above ₹2,50,000.
So the department must deduct GST TDS while making payment.
GST TDS Rate
The deduction rate is small and depends on whether the supply is within the same state or between states.
For supplies within the same state, the deductor keeps aside:
- 1% under CGST
- 1% under SGST
- Total deduction = 2%
Example
A contractor in Delhi supplies services worth ₹3,00,000 to a Delhi government department.
The department deducts:
- ₹3,000 as CGST TDS
- ₹3,000 as SGST TDS
- Total deducted = ₹6,000
For supplies between different states
If the supply is between two states, the deduction is: 2% under IGST
Example
A supplier in Chandigarh provides services to a government office registered in Delhi.
The department deducts: 2% of the taxable value as IGST TDS
When GST TDS Is NOT Required
There are several situations where TDS does not apply. These rules often confuse beginners, so let’s break them down clearly.
1. Contract value is below ₹2,50,000
If the taxable value of a contract is ₹2.5 lakh or less, TDS is not required. Even if the invoice total becomes higher because of GST, the rule still depends only on the taxable value.
2. Multiple small contracts
Sometimes a department signs separate contracts with the same supplier. If each contract individually is below ₹2,50,000, TDS is not deducted even if the total combined value crosses the limit.
Example:
A supplier signs two separate contracts:
- Contract 1: ₹2,20,000
- Contract 2: ₹2,10,000
Since each contract is below ₹2.5 lakh, TDS does not apply.
3. Exempt goods or services
GST TDS is not deducted on supplies that are fully exempt from GST.
Examples include:
- Certain educational materials
- Goods or services notified as exempt under GST law
Also, items like petrol, diesel, natural gas, aviation turbine fuel, and alcoholic liquor are outside GST. So TDS is not applicable there.
4. Payment to an unregistered supplier
If the supplier is not registered under GST, the deductor does not deduct GST TDS.
5. Reverse charge cases
When GST is required to be paid under reverse charge by the buyer, TDS rules do not apply.
6. Special location mismatch situations
Sometimes the supplier and place of supply are in one state but the buyer is registered in another state.
In such cases, TDS is not deducted because the tax adjustment becomes difficult across states.
On Which Amount Is TDS Calculated?
This is another small but important rule.
GST TDS is calculated only on the taxable value, not on the GST portion shown in the invoice.
| Particular | Amount |
|---|---|
| Value of services | ₹4,00,000 |
| GST | ₹72,000 |
| Invoice total | ₹4,72,000 |
TDS is calculated on ₹4,00,000, not on ₹4,72,000.
Is GST Registration Required for TDS Deductors?
Yes.
Any organisation that is required to deduct GST TDS must take GST registration, even if it is not making taxable supplies.
Interestingly, these deductors can obtain registration using TAN (Tax Deduction Account Number) instead of PAN.
This provision mainly helps government departments.
Also, if a person is already registered as a supplier under GST, they must still take separate registration as a TDS deductor.
When Must the Deducted Tax Be Deposited?
The deducted amount must be deposited within 10 days after the end of the month in which the deduction was made.
For example, if TDS is deducted in April, it must be deposited by 10th May.
The deductor files Form GSTR-7 on the GST portal while depositing this amount.
TDS Certificate Under GST
Once the deductor files the return, the GST portal automatically generates a TDS certificate in Form GSTR-7A.
This certificate becomes available online for the supplier.
From practical experience, suppliers often check this certificate to confirm that the deduction has been properly reported.
How the Supplier Gets the Benefit of TDS
After the deductor files the return, the deducted amount appears in the supplier’s electronic cash ledger on the GST portal.
The supplier can then use this balance to:
- Pay GST liability
- Adjust tax payments during return filing
If any balance remains unused, it can also be claimed as a refund.
Interest, Late Fees and Penalty
If the deductor fails to deposit the deducted amount on time, additional charges apply.
Here’s how it works:
- Interest: 18% per year on delayed payment
- Late fee: ₹50 per day (₹25 CGST + ₹25 SGST), capped at ₹2,000
If someone:
- fails to deduct TDS
- deducts less amount
- deducts but does not deposit it
then a penalty can also be imposed under GST law. If no tax was deducted in a month, the late fee is fully waived.
When Did GST TDS Start in India?
GST TDS provisions became effective from 1 October 2018.
Since then, government departments, PSUs and certain notified bodies must follow these rules while making payments to supplier

Conclusion
GST TDS is a mechanism where certain government-related buyers deduct a small portion of tax while paying suppliers and deposit it directly with the GST department.
For beginners, the key things to remember are:
- TDS applies mainly to government bodies and PSUs
- It is required when taxable contract value exceeds ₹2,50,000
- The deduction rate is 2% in total
- The deducted amount becomes credit in the supplier’s electronic cash ledger
Understanding this system helps suppliers working with government organisations avoid confusion when they notice deductions in their payments.

Frequently Asked Questions: FAQs on GST TDS in India
Many beginners confuse GST TDS with income tax TDS or feel unsure about when it applies. The FAQs below answer both basic questions and deeper practical doubts that people commonly search on Google, Bing, ChatGPT, and other platforms.
What is TDS under GST? Is TDS applicable to GST?
TDS under GST means a specified buyer (usually a government office or PSU) deducts a small portion of GST while paying a supplier and deposits that amount with the government.
The supplier later sees this amount in their GST account and can use it to pay tax. It is mainly used for payments made by government organisations.
Is GST TDS the same as TDS under Income Tax?
No, they are completely different.
Income Tax TDS is usually deducted from salary, interest, or contractor payments under the Income Tax Act.
GST TDS applies only when certain government bodies make payments for taxable goods or services under GST.
Who is required to deduct TDS under GST?
Most government-related organisations deduct GST TDS. This includes Central and State Government departments, local authorities, government agencies, public sector undertakings (PSUs), and government-controlled bodies where the government holds more than 51% control.
When does GST TDS apply to a payment?
GST TDS applies when the taxable value of a contract for goods or services is more than ₹2,50,000, excluding GST.
If the value is below this limit, no deduction is required.
How much GST TDS is deducted?
The total deduction is 2% of the taxable value.
If the supplier and buyer are in the same state, it is split as 1% CGST and 1% SGST.
If they are in different states, 2% IGST is deducted.
On which amount is GST TDS calculated?
TDS is deducted on the taxable value of supply, excluding GST. This means the recipient should not include CGST, SGST, UTGST, or IGST while calculating the TDS amount. The deduction is made on the net value of goods/services supplied, as shown in the invoice or relevant document.
For example, if the taxable value is ₹10,000 and GST is ₹1,800, TDS is calculated on ₹10,000 only.
Do government offices always need GST registration for TDS?
Yes, if a government office needs to deduct GST TDS, it must obtain GST registration as a TDS deductor. However, if no payments requiring TDS are made, registration may not be necessary at that stage.
What are the main responsibilities of a DDO (Drawing and Disbursing Officer) in GST TDS?
The DDO must check the contract value, verify GSTIN of suppliers, deduct TDS when required, deposit the deducted amount with the government, file GSTR-7 return, and ensure the TDS certificate is generated for the supplier.
When is GST TDS not required to be deducted?
GST TDS is not required when the contract value is ₹2.5 lakh or less, when goods or services are exempt from GST, when payment is made to an unregistered supplier, or when supplies happened before GST TDS rules started in October 2018.
How does the supplier get the benefit of GST TDS?
After the deductor files the return in Form GSTR-7, the deducted amount appears in the supplier’s Electronic Cash Ledger on the GST portal. The supplier can then use that balance to pay GST while filing returns.
What happens if GST TDS is deducted but not deposited on time?
If the deductor delays depositing the tax or filing the return, interest and late fees may apply. In serious cases, penalties may also be imposed under GST rules.
Do I need to file a GST TDS return every month?
The deductor must file Form GSTR-7 only for the months in which TDS has been deducted. If no deduction was made in a particular month, filing the return for that month is not required.
