Blocked Credits Under GST: The Complete Guide to Section 17(5)

For accountants, finance heads and business owners who book purchases every month and want to claim only the credit the law allows.

An accountant sorting purchase bills into eligible and blocked trays

Blocked credits under GST are the input tax a registered business pays but may never set off, however genuine the purchase. Section 17(5) of the CGST Act lists them: staff meals, cars for directors, club memberships, gifts and building works are the usual suspects in an Indian SME's books.

The trap is that these purchases look like any other bill. The supplier files it, it appears in GSTR-2B, and a busy accountant claims it with the rest. The credit is then reversed later, often with interest, when a notice or an audit catches it.

This guide lists what is blocked, the exceptions, an illustrative example and how Apragya keeps blocked credit out of the claim.

What Section 17(5) blocks

Section 17(5) overrides the general rule that tax on business purchases is creditable. If a purchase falls in one of its categories, the credit is blocked even when the invoice is valid, the goods were received and the supplier paid the tax.

Most categories carry exceptions. A car dealer may claim credit on cars bought for resale, a caterer on food bought to serve customers, and an employer on canteen or insurance costs that a law obliges it to provide. Read each item with its exception before blocking a bill.

The main categories are below. The wording has been amended several times, including on construction of immovable property, so check the current text of the section before you rely on a borderline case.

  • Motor vehicles for carrying up to 13 people, with their repairs and insurance, unless used for resale, passenger transport or driving training
  • Vessels and aircraft, outside the uses the section allows
  • Food and beverages, outdoor catering, beauty treatment, health services and cosmetic surgery, unless used for the same kind of outward supply or required by law
  • Club, health and fitness memberships, and travel benefits such as leave travel for employees
  • Life and health insurance, unless the law makes it compulsory for the employer
  • Works contracts and goods or services for building immovable property on your own account, other than plant and machinery
  • Tax paid under the composition scheme
  • Goods lost, stolen, destroyed, written off, or given away as gifts or free samples
  • Goods or services used for personal consumption, and tax paid on demands involving fraud

Why blocked credit slips into the claim

It looks like any bill

A catering invoice carries the same GSTIN, HSN and tax as a raw material bill.

It sits in GSTR-2B

The supplier filed it, so the portal shows it as available credit.

Nobody reads the purpose

Month-end pressure means bills are claimed in bulk, not one by one.

Reversal costs more

Wrongly claimed credit comes back with interest, and sometimes a penalty.

An illustrative month at a Pune engineering firm

Take an illustrative 60-person machining firm in Pune. In one month its purchase register holds raw material, tooling, a sedan for the managing director, Diwali gift hampers for customers, a catered staff lunch and a contractor's bill for extending the office floor.

Which bills could carry credit

  • Steel and toolingUsed in manufacture, so the credit is eligible.Checked
  • Director's sedanA car for up to 13 people, not used for an allowed purpose.Mismatch
  • Gift hampersGoods given as gifts are blocked.Mismatch
  • Staff lunchFood for employees, with no legal obligation to provide it.Mismatch
  • Office floor worksConstruction on own account, not plant or machinery.Mismatch
  • CNC machine installPlant and machinery, so outside the construction block.Checked
Four of the six bills looked claimable in GSTR-2B but were blocked by Section 17(5).

The accountant tagged the four bills as blocked when they were booked, so the month's claim carried only the steel, tooling and machine installation. The blocked tax went to the cost of each item instead, and the GSTR-3B working showed it separately from the eligible credit.

Steel, tooling and the machine carry credit. The car, gifts, lunch and building works stay blocked.

How Apragya keeps ineligible ITC under GST out of the claim

Step 1 of 5

Book the purchase

Purchase invoices carry supplier GSTIN, HSN and tax, read from the PDF if you use document processing.

  1. Book the purchase: Purchase invoices carry supplier GSTIN, HSN and tax, read from the PDF if you use document processing.
  2. Record the block: Blocked credit for the period is recorded as an ITC adjustment, by tax head.
  3. Reconcile with GSTR-2B: The period's 2B is matched against the purchase register, so you see what the portal shows.
  4. Build GSTR-3B: Eligible credit, reversals and blocked amounts are kept apart in the working.
  5. Review and file: Your accountant reviews the working before the return is filed on the portal.

Handling the section 17(5) blocked credit list: spreadsheets or Apragya

A spreadsheet can hold a list of blocked items. It cannot sit next to each purchase, stop the credit reaching the return, or show later who marked a bill as blocked and why.

What sets Apragya apart on ITC not allowed under GST

One purchase record

The bill, the goods receipt and the credit decision stay together.

Bills read for you

Document processing pulls GSTIN, HSN and tax off supplier PDFs.

An agent to flag suspects

An agent built in the agent builder can flag bills whose HSN or description suggest a blocked category.

Human review

Flags are approved, rejected or modified by a person before they count.

Audit log

Who marked each adjustment, when, and from where.

Per company

Each company and registration keeps its own credit working.

Blocked credit is one part of the GSTR-2B reconciliation and the purchase register. For the wider rules, see the input tax credit guide.

Getting started with blocked credits

  1. List the purchase types your business makes that fall under Section 17(5).
  2. Note the exception, if any, that applies to your line of business.
  3. Tag those bills as blocked when they are booked, not at month end.
  4. Reconcile the month's GSTR-2B and check blocked items were not claimed.
  5. Have your tax adviser review borderline cases, especially construction.

Most businesses find that five or six recurring purchase types account for nearly all their blocked credit.

Blocked credits under GST, answered

If a blocked bill appears in GSTR-2B, must I claim it?
No. GSTR-2B shows what suppliers filed, not what you are entitled to. Blocked credit should be reported as ineligible in GSTR-3B as the current table instructions require.
Can I claim credit on a car used by the sales team?
Generally not, if it seats 13 or fewer people and is not used for one of the allowed purposes. Check the current text and take advice on your facts.
Is credit on gifts to employees blocked?
Goods given as gifts are blocked. The treatment of gifts to employees also involves valuation rules, so confirm the position with your adviser.
What happens to blocked tax in the books?
It becomes part of the cost of the item or expense, since it cannot be set off.
