What Is Job Work Under GST?
Here is the short version before the detail.
Job work under GST means any treatment or process a person carries out on goods that belong to another registered person. The owner of the goods is called the principal, and the one doing the work is the job worker. This is the exact wording of Section 2(68) of the CGST Act, 2017.
Think of a hosiery unit in Ludhiana that owns the cotton yarn but sends it out to a knitting unit to turn into fabric. The yarn never changes owner. Only a service, the knitting, gets supplied. That single fact, ownership staying with the principal, is what separates job work from an ordinary sale and drives every rule below.
What Does the Job Work Procedure Require?
Section 143 of the CGST Act lets a principal send inputs or capital goods to a job worker without paying tax, as long as the paperwork and timelines are followed. No tax invoice is raised for the goods themselves. Instead, they travel on a delivery challan under Rule 45.
| Rule | What it means in practice |
|---|---|
| Delivery challan, not invoice | Goods move on a challan showing quantity and description; no GST is charged on the goods sent |
| Return of inputs | Inputs must come back or be supplied onward within one year of being sent out |
| Return of capital goods | Capital goods have a three-year window; moulds, dies, jigs and fixtures have no limit |
| ITC-04 filing | The principal reports goods sent and received in Form GST ITC-04 |
| E-way bill | Inter-state movement to a job worker needs an e-way bill whatever the value |
Miss the one-year window and the law treats the original dispatch as a supply. The principal then pays GST on it, with interest, from the date the goods first left. So the clock matters.
Job Work Example
The figures below are an illustrative example, not a real client’s data.
A hosiery manufacturer in Ludhiana (the principal) sends cotton yarn worth Rs.3,40,000 to a nearby knitting unit. The yarn goes out on a delivery challan, so no GST applies to that Rs.3,40,000. The knitting unit converts it into fabric and bills only for its service.
| Line item | Amount |
|---|---|
| Value of yarn sent (on delivery challan) | Rs.3,40,000 |
| Job work charges billed by knitter | Rs.48,000 |
| GST on job charges (5%, textile job work) | Rs.2,400 |
| Total invoice from job worker | Rs.50,400 |
| ITC the principal can claim | Rs.2,400 |
The fabric returns within a year, and the principal claims the Rs.2,400 as input tax credit. Note that GST hits only the Rs.48,000 service, never the goods.
Job Work vs Outright Sale
Owners often confuse the two because both involve goods leaving the premises. The difference sits in who owns the goods.
| Aspect | Job work | Outright sale |
|---|---|---|
| Ownership of goods | Stays with the principal | Passes to the buyer |
| Document used | Delivery challan | Tax invoice |
| GST charged on | Job work service only | Full value of the goods |
| Goods come back? | Usually yes, after processing | No |
What GST Rate Applies to Job Work?
Job work rates are not one flat number. Under the current schedule they run from 5% to 18% depending on the sector, set by Notification 11/2017-Central Tax (Rate) as amended. Much textile and textile-product job work sits at 5%, though dyeing and printing of textiles for a registered principal moved up to 12% from January 2022. Most other job work for a registered principal is 12%, and job work not covered by a specific entry falls to 18%.
Getting the rate and the timeline wrong is where money leaks. An engineering unit in Aurangabad that machines castings for a registered principal, or a pharma packaging job worker in Baddi, each carries a different rate and a different reporting duty. A missed ITC-04 or a lapsed one-year window can convert a routine dispatch into a taxable supply overnight. When the slab is unclear, confirm it with your CA rather than guessing, because a wrong rate on a high-volume account adds up fast across a year.
Let the Software Track Every Challan and Return
Job work falls apart on paperwork, not on the work itself. A challan raised without a matching return record, or an e-way bill missed on an inter-state consignment, is what triggers notices. Moving that trail to a digital document workflow is what stops the small misses from becoming big ones.
Petpooja Invoice generates GST-ready documents, e-invoices and e-way bills, and keeps a centralised view of stock so goods sent out for processing stay visible against their return date. It ties into your GST return filing workflow, and you can size the tax on any job charge with the GST calculator before you bill. For the wider tax picture, our GST guide covers the basics.
Frequently Asked Questions
Not quite. Manufacturing usually means you own the raw material and the finished product. In job work the goods stay owned by the principal, and the job worker only supplies a service on them.
Nobody, at the point of sending. The goods travel on a delivery challan with no tax. GST applies only to the job worker’s service charge, and if the goods are not returned within the time limit, the principal then pays tax on the original dispatch.
One year for inputs and three years for capital goods, counted from the date they were sent. Moulds, dies, jigs, fixtures and tools have no time limit. Miss the window and the dispatch is treated as a supply.
It is the statement a principal files to declare goods sent to and received back from job workers. Businesses with turnover above Rs.5 crore file it half-yearly; those up to Rs.5 crore file it once a year.
Only if their turnover crosses the registration threshold, like any other supplier. Below it, registration is optional, though many register so the principal can supply finished goods directly from the job worker’s premises.
