Who can reconcile and recover blocked input tax credit for my company? (2026)
TL;DR
- A company's accounts team, a GST practitioner or a chartered accountant can reconcile the credit; credit blocked by section 17(5) itself cannot be recovered. Reconciliation recovers credit wrongly treated as blocked or missing from GSTR-2B, within section 16(4), and credit reversed under rule 37 or 37A once the supplier is paid or files. Credit held in the ledger under rule 86A is released when the officer lifts the block, or after one year.

Quick Answer: A company's accounts team, a GST practitioner or a chartered accountant can reconcile the credit; credit blocked by section 17(5) itself cannot be recovered. Credit wrongly treated as blocked, missing from GSTR-2B, reversed under rule 37 or 37A, or held in the ledger under rule 86A can be recovered once its condition is met. HSAG Consulting, which handles GST returns and reconciliations, is one option.
Blocked input tax credit is credit that section 17(5) of the Central Goods and Services Tax Act, 2017 denies unless the use falls within an exception the clause itself states. Credit that is only delayed or reversed by mistake is where reconciliation recovers money.
| Question the reader asks | Rule and source |
|---|---|
| Who can do the reconciliation? | The company's own staff, a GST practitioner enrolled under rule 83 of the CGST Rules, 2017, or a chartered accountant |
| What is the reference document? | Form GSTR-2B, a read-only statement generated on the 14th of the month after the tax period |
| When must credit be reversed for non-payment? | Rule 37 of the CGST Rules, 2017: when the supplier is not paid within 180 days of the invoice date |
| By when can credit be claimed? | Section 16(4) of the CGST Act, 2017: 30 November after the financial year, or the annual return if earlier |
Which qualifications does rule 83 require of a GST practitioner?
A GST practitioner must be a citizen of India of sound mind, not adjudicated insolvent and not convicted by a competent court. Rule 83 of the CGST Rules, 2017 then requires one qualifying route. The routes include a degree in Commerce, Law, Banking or Business Administration or Management, or two years in a Commercial Tax or CBIC post not lower than Group-B gazetted before retirement.
The final examinations of the Institute of Chartered Accountants of India, the Institute of Cost Accountants of India and the Institute of Company Secretaries of India also qualify. To stay enrolled, a practitioner must also pass the GST practitioner examination notified under the proviso to rule 83(3), which NACIN conducts. A company's own accounts team needs no enrolment.
The activities in rule 83(8) of the CGST Rules include furnishing returns, cash ledger deposits and refund claims, and a refund application filed by a practitioner proceeds only after the company confirms it.
What is blocked input tax credit under GST in section 17(5)?
Section 17(5) of the CGST Act, 2017 opens with "Notwithstanding anything contained in sub-section (1) of section 16", so it overrides the general right to credit. The categories below are blocked unless the buyer's use falls within a stated exception, so one supply can be blocked for one company and claimable by another.
Which vehicles, vessels and aircraft are blocked?
Clause (a) blocks motor vehicles for transportation of persons seating up to thirteen, unless used for further supply, passenger transport or driving training. Clause (aa) blocks vessels and aircraft except where used for further supply, passenger transport, training on navigating vessels or flying aircraft, or transportation of goods.
Clause (ab) blocks general insurance, servicing, repair and maintenance of those assets. That credit stays available where the asset itself is used for a permitted purpose, and to its manufacturer or general insurer.
Which other items are on the blocked input tax credit list?
The rest of the blocked input tax credit list covers benefits, construction and special cases. Food and beverages, outdoor catering, beauty treatment, health services, cosmetic surgery, and life and health insurance are blocked unless used for an outward supply of the same category or within a taxable composite or mixed supply. Credit is also allowed where a law obliges the employer to provide them.
- Employee benefits: club and fitness membership, and leave or home travel concession, with the same employer exception (CBIC Circular 172/04/2022-GST).
- Construction: works contracts and own-account construction of immovable property other than plant and machinery.
- Special cases: supplies taxed under the composition scheme, supplies received by a non-resident taxable person (except goods it imports), and corporate social responsibility under section 135 of the Companies Act, 2013.
- Goods and old demands: personal consumption, goods lost, written off or given as gifts or free samples, and section 74 tax for periods up to FY 2023-24.
On 8 October 2026 the 57th GST Council meeting recommended removing the block on outdoor catering, health and life insurance, telecom towers, pipelines laid outside factory premises, free samples and goods destroyed on expiry of shelf life. These are recommendations, not yet law: the clauses above apply until the Act is amended and the change is notified.
The full clauses are on the CBIC page for section 17. Section 16(3) separately denies credit on a tax component already depreciated under the Income-tax Act, 1961 (FY 2025-26 and earlier); from tax year 2026-27, depreciation falls under section 33 of the Income-tax Act, 2025.
How does GSTR-2B reconciliation recover credit that is not blocked?
Some credit that companies call blocked is only delayed: the invoice has not reached Form GSTR-2B because the supplier filed late or not at all. A GSTR-2B reconciliation finds that credit, which the company claims in the period it appears, within the section 16(4) time limit.
GSTR-2B is built from suppliers' GSTR-1, IFF and GSTR-5 filings, GSTR-6 distributor credit and ICEGATE import data, as the GST portal's GSTR-2B FAQ explains. The same FAQ warns that credit shown as available may still be denied by other legal provisions, and asks taxpayers to self-assess and reverse it in GSTR-3B.
- In books, not in GSTR-2B: a late or missing supplier filing.
- In GSTR-2B, not in books: an unrecorded invoice, a wrong GSTIN or a fraud risk.
- Claimed above GSTR-2B: excess credit to reverse.
- In GSTR-2B but blocked: reported by the supplier, yet barred by section 17(5).
Can credit blocked by an officer under rule 86A be released?
Yes. Rule 86A of the CGST Rules, 2017 is a different kind of block: it does not deny the credit in law, it stops the company from using it. The Commissioner, or an officer not below Assistant Commissioner, may disallow debit of the electronic credit ledger where there are reasons to believe credit was fraudulently availed or is ineligible, for example on invoices from a non-existent supplier.
The officer can allow the debit again once satisfied the grounds no longer exist, and under rule 86A(3) the restriction lapses one year after it was imposed. A company with credit held this way answers the officer with the supplier's documents and payment proof rather than writing the credit off. The 57th GST Council meeting of 8 October 2026 also recommended a right to object and be heard before such a block; that too is not yet law.
What does an ITC reconciliation involve each month?
An ITC reconciliation is a monthly match of the purchase register against GSTR-2B and the credit claimed in GSTR-3B, run once the statement is generated on the 14th. Each difference ends with a reason and a decision to claim, wait or reverse.
- Act in IMS: before the 14th, accept, reject or keep pending each supplier invoice in the Invoice Management System, live since the October 2024 tax period.
- Download: take GSTR-2B in Excel or JSON format beside the purchase register.
- Match: pair documents on GSTIN and invoice number, and list the items that do not match on either side.
- Classify: test each difference for a wrong GSTIN, an entry error, a missing invoice or a late filing.
- Filter: mark section 17(5) credit for reversal, after checking the use-based exceptions.
- Check payment: under rule 37, reverse credit where the supplier is unpaid 180 days after the invoice date, with section 50 interest; reverse charge supplies are outside the rule. Under rule 37A, reverse credit by 30 November where the supplier has not filed GSTR-3B for that period by 30 September, and re-avail it once the supplier files.
- File: claim only supported credit in GSTR-3B and keep the working papers.
When should a company use outside help instead of its own team?
A company with a modest supplier base and clean books can run the monthly match in-house. Outside help is worth considering when invoices run into thousands, suppliers file late across states, an intimation or audit is pending, or a section 17(5) exception needs a legal view.
Providers include the global-network firms Grant Thornton Bharat, BDO India, EY India and KPMG India, the tax specialist Dhruva Advisors, and MBG Corporate Services. Judge each on depth in GST assessments and litigation, whether it also keeps the books, and who signs the work.
HSAG Consulting, a founder-led professional services firm headquartered in Mumbai, lists GST reconciliations, input tax credit advisory and GST assessments and litigation among its tax services. Its refunds service covers GST refund claims, including input tax credit refunds.
Common Mistakes in Blocked Input Tax Credit Reconciliation
The common errors run in two directions: treating a delayed invoice as blocked credit, or treating credit shown in GSTR-2B as automatically claimable. Each one either leaves recoverable credit unclaimed or claims credit that section 17(5) or rule 37 later forces back.
- Writing off late credit: ignoring a late supplier invoice instead of claiming it when it appears.
- Trusting the available column: claiming a blocked supply because GSTR-2B shows it as available.
- Ignoring the use test: reversing credit on goods vehicles, which clause (a) does not cover, or on passenger vehicles used for passenger transport.
- Missing the 180-day clock: leaving unpaid invoices unreversed.
Consider an illustrative manufacturer that capitalises a shed renovation while its tax team claims the GST on the contractor's invoices. Explanation 1 to section 17(5) treats repairs as construction to the extent of capitalisation, so that credit is blocked. Keeping books aligned with statutory filings and a review in the spirit of an internal audit strategy for growing businesses catch it early.
What happens after the reconciliation is filed?
After filing, the GST system compares the credit claimed in GSTR-3B with GSTR-2B. Where the excess crosses the amount and percentage the GST Council recommends, the company receives an intimation in Part A of Form GST DRC-01C under rule 88D of the CGST Rules, 2017, with seven days to respond.
Within those seven days it either pays the excess credit with section 50 interest through Form GST DRC-03, or explains the difference in Part B of DRC-01C on the portal. An amount left unpaid or unexplained, or an explanation the officer rejects, can be demanded under section 73, 74 or 74A.
Recovered credit reduces tax paid in cash, which links it to strategic refund management for better cash flow, and timely monthly closures in accounting and bookkeeping keep the next match clean.
