GST invoice format for an earthmoving and excavation contractor (JCB, excavator hire)

An earthmoving contractor bills either for work done, such as cubic metres excavated, levelled or filled, or for machine hire by hour or month. Work-based bills use SAC 995433, excavating and earthmoving services, under construction services at 18%. Hire of a JCB, excavator or roller with operator is leasing of construction machinery under SAC 997313, taxed at the rate applicable to the machine, which for excavators and loaders under HSN 8429 is 18%. The invoice should show hour-meter readings, machine registration and site.

Extra fields a earthmoving and excavation contractor invoice needs

Machine type and registration number: Clients pay for a specific machine at a specific site. Printing machine type, model and registration or chassis number links the bill to the logbook and gate entries.
Hour-meter readings or log sheet: Hire is billed on running hours. Opening and closing hour-meter readings, or the log sheet number signed by the site supervisor, are the strongest evidence for the hours charged.
Minimum hours and idle time: Many hire contracts guarantee a minimum number of hours per day or month. Showing the minimum and any idle charges explains why billed hours exceed the logged working hours.
Fuel: included or client-supplied: Hire rates differ by whether diesel is supplied by you or the client. Stating fuel terms prevents disputes and affects the value of the supply.
Mobilisation and demobilisation: Transporting a machine to site on a trailer costs money. Billing mobilisation separately makes it visible and taxable as part of your service.
Quantity measured: Work-based contracts list cubic metres excavated and the lead distance for disposal. Recording these makes the bill comparable with the client's survey.

GST rules that matter for a earthmoving and excavation contractor

Excavation work versus machine hire

When you are responsible for completing excavation or levelling to the client's levels and are paid per cubic metre, you are supplying a construction service under SAC 995433, excavating and earthmoving services, taxed at 18%. When the client directs the machine and pays per hour, you are leasing construction machinery with operator under SAC 997313. Both are taxable, but the classification determines the rate logic and how the client reports the expense.

Rate on machinery hire follows the machine

The services rate notification treats leasing or renting of goods with or without operator, where not specified elsewhere, at the same rate as the supply of those goods. Self-propelled bulldozers, graders, excavators, loaders and road rollers under HSN 8429, and other earthmoving and boring machinery under 8430, are in Schedule II of Notification 9/2025 at 18%. Hire of these machines is therefore at 18%. If you rent out a tractor, which is in the 5% schedule, the rate changes accordingly.

Earthwork for Government at 18%

Composite works contracts involving predominantly earthwork, more than 75% of the contract value, provided to Government, and the corresponding sub-contracts, were at 12% until 21 September 2025. The 56th GST Council recommended and Notification 15/2025 implemented a move to 18% with input tax credit. Earthmoving contractors working on Government and local body jobs must update quotations and invoice templates for supplies after that date.

Diesel and the value of supply

If you buy diesel and include it in the hire rate, its cost is part of your taxable value. Diesel is outside GST, so you pay VAT on it without credit, which raises your cost. If the client supplies diesel free of charge, do not add it to your bill. Mention fuel terms on the invoice so the client's auditor understands the rate.

GST TDS and income-tax TDS

Government clients deduct 2% GST TDS on contracts above ₹2.5 lakh. Private clients may deduct income-tax TDS under section 194C or 194I for machinery hire depending on the contract. GST on your invoice is calculated on the full value; deductions appear only in the payment advice. Reconcile GSTR-7A certificates with your invoices every month.

Common billing mistakes

Billing machine hire under 995433 as earthwork when the client controlled the machine and paid per hour.
Continuing to charge 12% on earthwork contracts for Government after 22 September 2025.
Charging hours without hour-meter readings or log sheet references, leading to deductions.
Adding client-supplied diesel to the taxable value.
Not invoicing mobilisation, so the trailer cost is lost or later disputed.
Raising the monthly hire invoice without the client supervisor's signed log sheet, so idle days under the minimum-hours clause are deducted at payment.

Earthmoving and excavation contractor GST invoice: FAQ

What SAC code is used for JCB hire?

Hire of construction machinery such as JCBs and excavators with or without operator is coded 997313. Earthwork billed by quantity uses 995433.

What is the GST rate on JCB rental?

Hire of excavators and backhoe loaders attracts 18%, matching the rate for the machines under HSN 8429.

Is earthwork for Government still at 12%?

No. From 22 September 2025, composite works contracts predominantly of earthwork provided to Government were moved to 18% with input tax credit.

Can I claim credit on the excavator I bought?

Yes, credit on capital goods used for taxable outward supplies is available. Motor vehicles have special restrictions, but excavators and loaders are machinery, not passenger vehicles.

Should hour-meter readings be printed on the invoice?

GST does not require it, but readings or log sheet references are the best evidence of hours and reduce disputes with site engineers.
