GST on Job Work — Threshold, rates & documentation

Introduction

Job work is an important part of the manufacturing and processing industry under the Goods and Services Tax (GST) regime. Businesses often send raw materials, semi-finished goods, components or other inputs to another person for processing or manufacturing without transferring ownership of the goods.

GST law provides specific provisions for job work, including the treatment of goods sent for processing, Input Tax Credit (ITC), documentation, e-way bill requirements and the time limit for returning goods.

This article explains the GST on job work, applicable rates, threshold limits and documentation requirements in 2026.

What is Job Work under GST?

Under Section 2(68) of the CGST Act, job work means any treatment or process undertaken by a person on goods belonging to another registered person.

The person who sends the goods for processing is called the Principal, while the person who carries out the treatment or process is called the Job Worker.

Example

Suppose a manufacturer sends steel sheets to another business for cutting, polishing and fabrication.

• Manufacturer = Principal
• Fabricator = Job Worker
• Steel sheets = Goods belonging to the Principal
• Cutting/polishing/fabrication = Job Work

The ownership of the goods remains with the Principal.

Is Job Work Taxable under GST?

Yes. Job work is generally treated as a supply of service under GST and is taxable at the applicable rate.

However, the GST rate depends upon the nature of the job work and the goods being processed.

Therefore, businesses should not assume that every job work service attracts the same GST rate.

GST Rate on Job Work

The applicable GST rate depends on the specific category of job work.

For example, certain job work services may fall under the standard rate applicable to the relevant service classification, while specific categories notified under the GST rate schedule may have different rates.

The correct SAC and GST rate should therefore be identified based on the exact nature of the processing activity.

Important Point

The GST rate should be determined based on:

• Nature of job work
• Goods being processed
• Whether the activity falls under a specifically notified job-work category
• Applicable SAC
• Relevant GST rate notification

Accordingly, businesses should verify the latest applicable rate before raising the invoice.

Is There Any GST Threshold for Job Work?

The normal GST registration threshold applies to a job worker based on the nature and location of the business and the applicable provisions of the CGST/SGST law.

A job worker whose aggregate turnover crosses the applicable registration threshold may be required to obtain GST registration.

However, registration requirements and taxability of a particular supply should not be confused.

A job worker may also be required to register in certain circumstances even if the normal turnover threshold is not crossed, depending on the applicable GST provisions.

Aggregate Turnover for Job Workers

Aggregate turnover is generally calculated on an all-India PAN basis and includes the relevant taxable supplies, exempt supplies, exports and inter-State supplies, subject to the statutory exclusions.

Therefore, a job worker should consider turnover from all relevant business activities while determining whether the registration threshold has been crossed.

GST on Job Work Charges

Once the job worker is registered and the service is taxable, GST is charged on the job work charges/service value.

For example:

Job work charges = ₹1,00,000

If applicable GST rate = 18%

GST = ₹18,000

Total invoice value:

₹1,18,000

The job worker should issue a tax invoice containing the required particulars.

Job Work and Input Tax Credit

Section 19 of the CGST Act provides specific provisions relating to ITC on inputs and capital goods sent for job work.

The Principal can claim ITC on eligible inputs and capital goods sent to the job worker, subject to the applicable conditions.

This is an important benefit because the Principal does not necessarily have to wait until the goods return from the job worker to claim eligible ITC.

Time Limit for Return of Inputs

Under Section 19, inputs sent to a job worker are required to be received back by the Principal or supplied from the job worker’s premises within the prescribed period.

The general time limit is:

1 year from the date of sending the inputs.

If the inputs are not returned or supplied within the prescribed period, the transaction may be treated as a deemed supply from the date on which the goods were originally sent.

Therefore, businesses should maintain proper records of goods sent for job work and monitor their return dates.

Time Limit for Capital Goods

For capital goods sent to a job worker, the prescribed period is generally:

3 years from the date of sending the capital goods.

If capital goods are not received back or supplied within the prescribed period, the applicable provisions may treat the transaction as a deemed supply from the date on which the capital goods were originally sent.

Important Difference

| Particulars | Time Limit |

| ————- | ———: |

| Inputs | 1 year |

| Capital Goods | 3 years |

These time limits are important for GST compliance and ITC protection.

Can Goods be Sent Directly to Job Worker?

Yes.

Under Section 19, the Principal can claim ITC on eligible inputs or capital goods even when such goods are sent directly to the job worker without first being received at the Principal’s premises, subject to the applicable conditions.

This is particularly useful for manufacturers who purchase raw materials and directly send them to their processing vendors.

Documentation for Job Work

Proper documentation is extremely important for job-work transactions.

The Principal should maintain appropriate records for goods sent to the job worker, including:

• Delivery Challan
• E-Way Bill, wherever applicable
• Job Work Register
• Purchase Invoice
• Job Work Order
• Tax Invoice issued by Job Worker
• Goods Receipt/Return Documents
• Records of goods sent and received
• Scrap/waste records
• Details of ITC claimed

Delivery Challan for Job Work

When goods are sent to a job worker without supply of the goods themselves, they can generally be moved under a Delivery Challan in accordance with the GST rules.

The delivery challan should contain the prescribed details, such as:

• Delivery Challan number
• Date
• Name and GSTIN of Principal
• Name and GSTIN of Job Worker
• Description of goods
• Quantity
• HSN, where applicable
• Place of supply, where applicable
• Signature

The delivery challan should clearly establish that the goods are being moved for job work and not being sold to the job worker.

E-Way Bill for Job Work

An e-way bill may be required when goods are transported for job work, subject to the applicable provisions and threshold requirements.

The person responsible for the movement should ensure that the required e-way bill is generated before transportation where applicable.

For inter-State movement of goods by a Principal to a job worker, the relevant GST provisions and e-way bill requirements should be checked carefully.

GST Invoice by Job Worker

After completing the job work, the job worker generally raises an invoice for the job work/service charges.

For example:

Job Work Charges: ₹2,00,000

GST @ 18%: ₹36,000

Total: ₹2,36,000

The invoice should contain all mandatory particulars under GST law.

Job Work and Scrap/Waste

During processing, scrap or waste may arise.

GST treatment depends upon who is responsible for the scrap/waste and the applicable provisions.

Where the job worker is registered, the job worker may supply the waste/scrap as applicable and discharge GST.

Where the job worker is unregistered, the Principal may be required to account for the scrap/waste in accordance with the applicable GST provisions.

Therefore, the agreement between the Principal and Job Worker should clearly specify how scrap and waste will be handled.

Job Work vs Manufacturing

Job work and manufacturing are not always the same.

Job Work:

• Goods belong to another person.
• Job worker performs treatment or processing.
• Ownership generally remains with the Principal.

Manufacturing:

• Manufacturer may use its own raw materials.
• Goods may belong to the manufacturer.
• Manufacturing may involve creation of a new product.

The GST treatment should be determined based on the actual nature of the transaction rather than merely the terminology used in the agreement or invoice.

What if the Principal Does Not Receive the Goods Back?

This is one of the most important compliance points.

If inputs are not returned or supplied within one year, or capital goods are not returned or supplied within three years, the relevant provisions under Section 19 can result in the transaction being treated as a deemed supply from the date the goods were originally sent.

This can create additional GST liability and may also affect ITC-related compliance.

Therefore, businesses should maintain a proper job-work ageing report.

Job Work Register — Recommended Format

Businesses can maintain a register containing:

| Date | Challan No. | Goods | Qty. | Job Worker | Date Returned | Balance Qty. |

| ———- | ———– | ———— | —: | ————— | ————- | ———–: |

| 10-04-2026 | JW-001 | Steel Sheets | 100 | ABC Fabricators | 25-04-2026 | 0 |

| 15-04-2026 | JW-002 | Components | 500 | XYZ Works | 20-05-2026 | 0 |

This helps the Principal track goods sent for job work and prevent expiry of the statutory return period.
