In short: the GST registration limit for contractors is set by Section 22(1) of the CGST Act at an aggregate turnover of twenty lakh rupees in a financial year, and ten lakh for supplies made from a special category State. The larger figure most owners have heard was notified for businesses dealing exclusively in goods, and machine hire is a supply of services. Aggregate turnover under Section 2(6) is computed all-India across everyone sharing your PAN, and Section 24 can make registration compulsory whatever your turnover is.

Ask a room of machine owners where the GST registration line sits and most will give you the bigger of the two numbers in circulation. It is the right answer to a different question.

That number was notified for suppliers dealing exclusively in goods. An owner who hires out an excavator is supplying a service. The Act’s own figure is the one that applies to him, and it is the lower one.

The GST registration limit for contractors, in the Act itself

Section 22(1) reads:

“Every supplier shall be liable to be registered under this Act in the State or Union territory, other than special category States, from where he makes a taxable supply of goods or services or both, if his aggregate turnover in a financial year exceeds twenty lakh rupees.”

The first proviso drops that to ten lakh rupees for a person making taxable supplies from any of the special category States. A further proviso lets the Government, at a special category State’s request and on the Council’s recommendation, raise that State’s figure up to twenty lakh.

Two structural points come straight out of the wording.

Registration is state-wise. The liability arises in the State or Union territory from where you make the taxable supply. Working across a border is a fact with consequences, which is why moving machines between states is a planning question as much as a logistics one — the movement side of it is covered in buying heavy machinery across states.

The trigger is aggregate turnover, not receipts. Which sends you to a definition that is wider than most owners expect.

What actually counts towards the figure

Section 2(6) defines aggregate turnover as:

“the aggregate value of all taxable supplies (excluding the value of inward supplies on which tax is payable by a person on reverse charge basis), exempt supplies, exports of goods or services or both and inter-State supplies of persons having the same Permanent Account Number, to be computed on all India basis but excludes central tax, State tax, Union territory tax, integrated tax and cess.”

Goes into the figure Stays out of it
All taxable supplies Central, State, UT and integrated tax, and cess
Exempt supplies Inward supplies you pay tax on under reverse charge
Exports  
Inter-State supplies of everyone sharing your PAN  

The phrase that catches people is “of persons having the same Permanent Account Number, to be computed on all India basis”. An owner running machine hire in one state and a second line of work elsewhere under the same PAN does not get two separate runs at the threshold. The figures are added.

Exempt supplies counting is the other surprise. Turnover you earn no tax on still pushes you towards the line that decides whether you register at all.

When the threshold stops mattering

Section 24 begins with “Notwithstanding anything contained in sub-section (1) of section 22” and then lists categories of persons required to be registered whatever their turnover. The ones an equipment business is most likely to meet:

Persons making any inter-State taxable supply. The first entry on the list.

Casual taxable persons making taxable supply — the occasional-transaction category.

Persons required to pay tax under reverse charge.

Persons required to deduct tax under Section 51, whether or not separately registered.

One caution, and it is an important one. Relief from some of these requirements has been granted by notification for certain suppliers of services, and a notification is not visible inside the Act. So Section 24 tells you where the law starts, not always where it ends for you. If any entry on that list looks like your business, that is the point to put the facts in front of your chartered accountant rather than to reason it out from the bare section.

Machine hire, works contract, and why the label matters

Section 2(119) defines a works contract as a contract for building, construction, fabrication, completion, erection, installation, fitting out, improvement, modification, repair, maintenance, renovation, alteration or commissioning of any immovable property, wherein transfer of property in goods is involved in the execution of such contract.

That last limb is the test. Putting a machine and an operator on a site at an hourly or daily rate does not ordinarily transfer property in goods to the customer; you are supplying the use of the machine and taking it home again. Taking on a piece of work to be completed, with material going into the structure, is a different animal.

Which of the two you are doing is settled by the contract you sign rather than by what the trade calls it. If your paperwork is loose on this, the note on the work order in construction is where to tighten it, and rate structures for hire work are set out in the equipment rental rate card.

Registration is a commercial decision as well as a legal one

Below the threshold you may have a choice, and the choice is not automatic.

Registration lets you claim input tax credit on the machine itself, which on a capital purchase is a large number — how that works is set out in GST input credit on construction equipment. It also carries a consequence at the other end of the machine’s life, because credit claimed on the way in is what the law reaches for when you sell, covered in GST on sale of old machinery.

Against that sit returns, records and the compliance time they take. And there is a market reality: serious clients and government departments generally expect a GSTIN before they place work, which is why registration tends to arrive with the first real order rather than with the threshold. That is the same pattern you see on the government marketplace, described in GeM portal registration for contractors.

The bottom line

Work the Act’s figure, not the one in circulation. Add up everything under your PAN across the whole country, count exempt supplies in, and test it against the twenty lakh line — ten lakh if you supply from a special category State. Then read Section 24 and ask whether anything on that list describes you, because if it does the threshold never applied to you in the first place.

Getting this wrong is rarely deliberate. It happens because an owner tests one state’s receipts against a figure written for traders, and both halves of that sentence are wrong.

Planning the purchase that starts all of this? Compare current excavator models and prices and look at equipment finance options, so the registration position and the funding are decided before the invoice is raised rather than after.

Thresholds, notifications and exemptions under the GST law change, and several of the reliefs described here sit in notifications rather than in the Act. Confirm your own registration position with your chartered accountant before acting on it. Rates, schemes, specifications and prices change — confirm current terms with the OEM, dealer, bank or insurer before deciding.
