Job Work Time Limits, Deemed Supply and the Commissioner's Extension

Job Work Time Limits explained: this guide covers what it means, who it applies to, the step-by-step process, documents required, fees, due dates and penalties in India — so you can stay compliant with confidence and avoid costly mistakes.

Three questions decide every job work deadline: what kind of goods, when the clock started, and how many job workers touched them. Get any of the three wrong and the return date is wrong.

Inputs — one year. Capital goods — three years. Moulds and dies, jigs and fixtures, or tools — no time limit at all. Where goods are sent directly to the job worker, the period runs from the date of receipt by the job worker, not from the date of dispatch. Where goods pass through more than one job worker, "the entire process of job work from more than one job worker shall be considered for computing the period" — the clock does not restart. The Commissioner may extend, on sufficient cause, by a further one year (inputs) or two years (capital goods).

The three categories

Section 19(7) states the tooling exclusion in terms: "Nothing contained in sub-section (3) or sub-section (6) shall apply to moulds and dies, jigs and fixtures, or tools sent out to a job worker for job work." The Handbook confirms: "The above time limit of 1 year / 3 years for receiving back the said goods will not apply to moulds and dies, jigs and fixtures, or tools."

Why the exclusion exists. Tooling is placed with a job worker for the life of a product programme — often many years. Nothing about that indicates a disguised sale, and forcing an annual round trip of a die would serve no purpose.

But note what it does not do. The tooling exclusion removes the time limit; it does not remove the challan requirement, the ITC-04 reporting or the principal's accounts responsibility under section 143(2). The goods are still out on a challan and still the principal's to account for.

And "input" is wider than it looks. The Explanation to section 143: "For the purposes of job work, input includes intermediate goods arising from any treatment or process carried out on the inputs by the principal or the job worker." Partially processed material remains an input, on the one-year clock.

When the clock starts

Ordinary despatch from the principal: from the date the goods are sent out.

Direct despatch from the vendor to the job worker: the proviso to section 19(3) — "where the inputs are sent directly to a job worker, the period of one year shall be counted from the date of receipt of inputs by the job worker" — and the proviso to section 19(6) says the same for the three-year capital goods period.

The Handbook adds the documentary route: "In case the inputs are sent directly to a job worker, the period of 1 year shall be counted from the date of receipt of inputs by the job worker. The bill to ship module be followed."

That start date is more generous than it first appears, and it is also harder to evidence. The principal must be able to show when the job worker received the goods — which means the job worker's inward record, not merely the vendor's invoice date, is part of the principal's file.

The chain rule

"When such inputs are further sent by one job worker to another, then the entire process of job work from more than one job worker shall be considered for computing the period of 1 year." The same is stated for the three-year capital goods period.

The clock does not restart at each stage. A component that spends four months at a machining job worker, then five at a plating job worker, then four at an assembler has used thirteen months and is already outside the period — whatever each individual movement looked like.

For a multi-stage supply chain this is the single most important operational control. The tracking has to be by original despatch date, not by current location. A system that ages goods from the date of the latest challan will report every consignment as comfortably within time, right up to the assessment.

The extension

The second proviso to section 143(1), inserted by section 29 of the CGST (Amendment) Act, 2018, notified through Notification No. 2/2019-Central Tax dated 29.01.2019 w.e.f. 01.02.2019:

"Provided further that the period of one year and three years may, on sufficient cause being shown, be extended by the Commissioner for a further period not exceeding one year and two years respectively."

So the outer limits are two years and five years. Note three features:

• The power is the Commissioner's, not the proper officer's.
• "Sufficient cause" must be shown — it is not automatic, and it is not a self-declared extension.
• The extension is capped; it cannot be granted a second time beyond the stated maxima.

And it must be sought before the period expires, in practice, because once the period has run the deeming in section 143(3) or (4) has already operated and the supply is deemed to have taken place on the day of despatch.

What the deeming actually costs

Where neither exit is taken in time, sections 143(3)/(4) and 19(3)/(6) deem the goods to have been "supplied by the principal to the job worker on the day when the said inputs were sent out."

Three consequences follow:

The invoice is current, the liability is not. Per Circular No. 38/12/2018, the principal issues the invoice and declares the supply in the return for the month in which the period expired, but pays tax "considering the supply was made… when the principal had sent the goods first for job work" — so interest runs from the original despatch date.

The value is the challan value. "without including cost of transportation and job work charges."

It is reported in GSTR-1. Rule 45(4): the deemed supply "shall be declared in FORM GSTR-1 and the principal shall be liable to pay the tax along with applicable interest."

A worked sense of the cost. Inputs of challan value ₹10,00,000 at 18% sent out on 1 May 2025 and never returned produce a liability of ₹1,80,000 arising 1 May 2025, invoiced in May 2026, with interest under section 50(1) at 18% for twelve months — roughly ₹32,400 — before any penalty exposure.

Two things that are not a deemed supply

Goods lost or destroyed at the job worker's premises. The Handbook resolves the section 17(5)(h) versus section 19(3) question: "Since goods are lost or destroyed, section 17(5)(h) will be applicable and the principal is required to reverse the credit on inputs or capital goods, and it will not be treated as deemed supply."

A dispute in which the job worker keeps and sells the goods. Where the job worker sells them in the open market as consideration for unpaid charges, "the valuation for the same goods should be considered transaction value by the job worker and not market value of the said goods by the principal" — following Pawan Biscuits & Co. [2000 (120) ELT (24)] in the Supreme Court.

Key takeaways

• Inputs 1 year, capital goods 3 years, tooling no limit — moulds and dies, jigs and fixtures, or tools are excluded by section 19(7).
• Tooling still needs a challan, ITC-04 reporting and accounts — only the clock is removed.
• "Input" includes intermediate goods, so partially processed material stays on the one-year clock.
• On a direct despatch, the clock starts on the job worker's receipt — evidence that date.
• Across a chain of job workers the clock does not restart; track by original despatch date.
• The Commissioner may extend by one further year / two further years on sufficient cause — outer limits two and five years.
• The deeming backdates the supply to the despatch date, so interest runs from then, on the challan value, reported in GSTR-1.
• Loss or destruction is a 17(5)(h) reversal, not a deemed supply.
