Start with section 16 of the Central Goods and Services Tax Act, 2017, then apply the specific blocked-credit rules in section 17(5), the project’s output supply, the builder’s legal role and any residential-promoter notification. This explainer reflects the CGST framework and CBIC material available on 13 October 2026; rates, forms, deadlines and notifications can change.
Section 16 can make eligible business inputs creditable when the statutory conditions are met. Section 17(5), however, blocks important construction-related credits, including many works-contract services and goods or services used to construct an immovable property on the taxpayer’s own account. A separate post-1 April 2019 scheme for specified residential apartments imposes restrictive or no-ITC conditions and an 80% registered-supplier test. The correct answer is therefore project-specific, not a blanket yes or no.

Start with section 16: the baseline ITC test
Section 16(1) permits a registered person to take credit for input tax on goods or services used, or intended to be used, in the course or furtherance of business, subject to statutory conditions, restrictions and the prescribed procedure. The full text is available in the CBIC publication of the CGST Act, 2017. Passing this baseline test does not override a specific block in section 17(5).

Conditions that must be evidenced
- Registration and business nexus: the claimant must be a registered person and connect the inward supply to business activity.
- Valid document: hold an eligible tax invoice, debit note or another document specified by the Act and rules.
- Receipt: goods or services must be received. Where an invoice covers delivery in lots or instalments, credit is available on receipt of the last lot or instalment.
- Tax payment and return: the supplier’s tax must be paid to the Government through the statutory mechanism, and the recipient must furnish the relevant return.
- Supplier payment: if the recipient does not pay the supplier the value plus tax within 180 days, an adjustment with interest is required under the prescribed rules. Credit can generally be re-availed after payment, subject to the Act’s treatment and exceptions.
Time limit for taking credit
Section 16(4) generally bars credit after 30 November following the end of the financial year to which the invoice or debit note relates, or the filing of the relevant annual return, whichever is earlier. The 2024 amendments inserted retrospective subsections 16(5) and 16(6) for specified cases and periods. CBIC Circular 237/31/2024-GST, dated 15 October 2024, explains implementation. Treat 30 November as the general rule, not an absolute answer for every historical invoice; check whether the invoice facts fall within those exceptions.

Section 17(5): the construction credits most often blocked
After section 16, test every inward supply against section 17(5). The construction blocks are fact-sensitive and depend on whether the recipient is a developer, works contractor or an entity constructing its own premises.
Works-contract services: section 17(5)(c)
ITC is blocked for works-contract services supplied for construction of an immovable property other than plant and machinery. There is an important exception where the received works-contract service is an input service for the recipient’s further supply of works-contract service. For example, a works contractor may be able to rely on the exception for a subcontracted service that is incorporated into the contractor’s onward taxable works-contract supply. The contract, actual use and onward supply must fit the statutory language; the exception is not a general developer exemption.
Construction on the taxpayer’s own account: section 17(5)(d)
Goods or services received for construction of an immovable property (other than plant and machinery) on the taxable person’s own account are blocked even when the property is used in the course or furtherance of business. The Act’s explanation treats “construction” as including reconstruction, renovation, additions, alterations or repairs, to the extent the cost is capitalised in the books. A commercial building used as an office, showroom, warehouse or rental asset does not become creditable merely because it supports a taxable business.

For these clauses, plant and machinery means apparatus, equipment and machinery fixed to earth by foundation or structural support and used for making outward supplies; the definition includes the relevant foundations and structural supports. It excludes land, buildings and other civil structures, telecommunications towers, and pipelines laid outside factory premises. Classification must be made for the actual asset under the statutory definition and current case law. Commercial usefulness alone is not enough to label a building or civil structure as plant and machinery.
Other section 17(5) blocks
The same provision also contains restrictions for specified passenger motor vehicles and conveyances (subject to listed business exceptions); specified food, catering, health, insurance, club and employee-travel benefits (again subject to exceptions); supplies taxed under the composition scheme; personal consumption; goods lost, stolen, destroyed, written off or given as gifts or free samples; and tax paid under the sections listed in the provision. A builder should examine the exact exception and use instead of assuming that every listed category is automatically blocked in every fact pattern.
Residential promoter projects: the post-2019 rate-and-credit scheme
CBIC’s current construction-services rate material sets special conditions for promoters supplying specified residential apartments. The scheme took effect from 1 April 2019 and is separate from the general section 16 test. The rates shown by CBIC are:
| Specified construction service | IGST rate shown by CBIC | CGST plus SGST/UTGST equivalent | Credit treatment |
|---|---|---|---|
| Affordable residential apartment | 1.5% | 0.75% + 0.75% | Subject to the notification’s restricted/no-ITC conditions |
| Other residential apartment | 7.5% | 3.75% + 3.75% | Subject to the notification’s restricted/no-ITC conditions |
These are rates for specified construction services under the notification, not a universal rate on every purchase made by a builder. Confirm that the supply, project and promoter status fall within the notification before applying them. The CBIC rates page reproduces the relevant conditions.
The 80% registered-supplier requirement
Under the scheme, the promoter must receive at least 80% of the value of specified inputs and input services from registered suppliers. The calculation excludes listed categories, including development rights, specified long-term land lease or FSI, electricity, high-speed diesel, motor spirit and natural gas. Inputs and input services on which tax is paid under reverse charge count as received from registered suppliers for this purpose.
If the threshold is not met, the promoter pays reverse charge on the shortfall at 18%. Cement purchased from an unregistered supplier has a separate reverse-charge rule at the applicable cement rate, with tax due in the month the cement is received. The 80% test is a compliance obligation under the promoter notification; it does not itself grant ITC on an otherwise blocked purchase.
Affordable-apartment figures in the 2019 explainer
CBIC’s 2019 real-estate explainer describes affordable housing as a carpet area up to 90 square metres in non-metropolitan cities or towns, or up to 60 square metres in specified metropolitan cities, with a value up to ₹45 lakh. Recheck the current notification wording and definitions before relying on these figures for a live project.
The notification’s no-ITC condition
CBIC’s 2019 presentation states, “Input tax credit shall not be available,” as a condition of the new residential real-estate rates. That sentence applies to the scope of that notified rate scheme; it is not a declaration that every builder, contractor or construction service recipient can never claim ITC. Read the complete notification, annexures and project facts.

Project classification and transition choices
“Builder” is not one legal category for ITC purposes. Identify the role and output before analysing an invoice.
| Role or fact pattern | Questions that control the result | Rules to test |
|---|---|---|
| Developer-promoter | What apartments are supplied, under which rate notification, and was a valid project option made? | Section 16, section 17(5), promoter conditions, 80% test and project allocation |
| Landowner-promoter | What is supplied to whom, and how are development rights, construction services and apartments documented? | Applicable promoter notification and project-specific apportionment |
| Works contractor | Is the received service used for a further taxable supply of works-contract service? | Section 17(5)(c) exception, contract scope and actual onward supply |
| Own-account builder or business owner | Is the asset an immovable property constructed for the taxpayer’s own use, and is the cost capitalised? | Section 17(5)(d), including the plant-and-machinery definition |
Ongoing projects that began before 1 April 2019
CBIC’s 2019 materials describe a one-time option for certain ongoing projects: construction and actual booking had both started before 1 April 2019, and the project was not complete by 31 March 2019. An eligible project could continue under the earlier effective rates with ITC if the option and records satisfied the applicable requirements. Do not infer an election from today’s rate or assume every older project qualified. Establish the construction date, first booking, completion status and election documents using the CBIC real-estate explainer.
Project-level allocation and final adjustments
The CGST Rules contain calculations, final adjustments and allocation mechanisms where inputs or input services are used across multiple real-estate projects. Project-wise records, completion or first-occupation facts and shared-cost allocations can change the amount that remains eligible. The CBIC compilation of the CGST Rules dated 14 November 2019 shows the mechanism, but later amendments must be checked before preparing a current computation.
A practical decision process for each invoice
- Identify the claimant: record whether the GSTIN belongs to a developer-promoter, landowner-promoter, works contractor or an entity constructing for its own account.
- Describe the outward supply: classify the apartments, works-contract service, rental or other output, and determine whether it is taxable, exempt or covered by a notified residential scheme.
- Classify the inward supply: distinguish ordinary goods, professional services, works-contract services, goods or services used for own-account construction, and plant or machinery used to make outward supplies.
- Apply the blocks: test section 17(5)(c) and (d) first for construction items, then review the other relevant blocks and exceptions.
- Check promoter conditions: for a notified residential project, verify the rate, no-ITC or restricted-ITC condition, 80% registered-supplier calculation, reverse-charge shortfall and cement treatment.
- Verify evidence and timing: retain the invoice, receipt evidence, supplier payment trail, return data and project coding; check the 180-day rule and the applicable section 16 deadline, including any section 16(5) or (6) exception.
- Allocate and adjust: apportion shared inputs and services between projects, record reversals or final adjustments required by the rules, and preserve the calculation supporting the filed return.
How common purchases should be analysed
| Purchase | Why the item name is not enough | Information needed before claiming |
|---|---|---|
| Cement or steel | It may be used in a blocked own-account or works-contract construction activity, or be affected by promoter reverse-charge rules. | Claimant role, project scheme, output supply, supplier registration, receipt month and section 17(5) classification |
| Architect, engineer or consultant fee | Professional services can support a project that is itself subject to a construction block or no-ITC promoter condition. | Service scope, project, capitalisation, output supply and applicable notification |
| Contractor or subcontractor invoice | Section 17(5)(c) distinguishes a recipient’s further supply of works-contract service from other construction use. | Contract terms, actual onward supply, property classification and tax invoice |
| Machinery fixed to earth | Qualifying plant and machinery can fall outside the immovable-property block, while buildings, civil structures and listed exclusions cannot. | Asset design, foundation, use in making outward supplies and statutory definition |
Records that support an ITC position
- Tax invoices, debit notes and purchase orders matched to the correct GSTIN and project.
- Goods-receipt notes, service completion evidence and lot-wise delivery records.
- Supplier payment records demonstrating compliance with the 180-day condition.
- Contracts showing whether a service is a works contract and whether there is an onward works-contract supply.
- Capitalisation schedules identifying own-account construction, repairs, additions and alterations.
- Engineering and asset records supporting a plant-and-machinery classification where claimed.
- Project-wise inward-supply registers, shared-cost allocation workings and reversal or final-adjustment calculations.
- Promoter rate-option records, booking and construction dates, registered-supplier percentages, reverse-charge challans and annual statements where the notification requires them.
CBIC also publishes sector-specific guidance through its Sectoral FAQs. Use the current statute, rules, notification and circulars together; a vendor’s invoice description or an accounting label cannot by itself establish eligibility.
Common questions
Can builders claim input tax credit under GST?
Sometimes. A registered builder must first satisfy section 16, then show that no section 17(5) block or promoter no-ITC condition applies. The answer depends on the builder’s role, output supply, project option and the use of each inward supply.
Is GST input credit allowed on construction materials?
There is no universal yes or no for materials. Cement, steel and similar goods can be part of blocked own-account construction, a works-contract activity, a qualifying plant-and-machinery installation or a notified residential project with restricted credit. Apply the project and use tests rather than the material’s name.
Is ITC blocked on works contract for construction?
Section 17(5)(c) generally blocks works-contract services used to construct an immovable property other than plant and machinery. It preserves an exception when the received works-contract service is an input service for further supply of works-contract service, provided the facts and contracts genuinely fit that exception.
Can a builder claim GST credit on cement and steel?
Only after analysing the claimant, project scheme, output supply, construction purpose, supplier status and section 17(5). Under the residential promoter scheme, purchases from unregistered suppliers also affect the 80% calculation and can trigger reverse charge; that procurement rule is not a general ITC entitlement.
What is the 80% rule in GST for builders?
For the specified residential-promoter scheme, at least 80% of the value of specified inputs and input services must be received from registered suppliers, subject to exclusions in the notification. A shortfall attracts 18% reverse charge, and cement from an unregistered supplier has its own reverse-charge treatment. The calculation is project-specific.
Can ITC be claimed on residential construction under GST?
Under the new residential rate scheme, the notified rates carry restricted or no-ITC conditions and promoter compliance requirements. An older project may have a valid transition election, while a works contractor’s onward supply can involve the section 17(5)(c) exception. Confirm the project’s dates, option, notification coverage and records before claiming credit.
Bottom line for a live project
Do not decide ITC from the word “builder” or from a purchase list. Map the legal role, outward supply, project classification, construction purpose, rate option and invoice dates; then apply section 16, section 17(5), the residential-promoter notification and the project-allocation rules. Because the law and rate notifications change, a GST professional should review the contracts, project records and current text before a material credit is taken or reversed.
