TDS on Contractor Payments Calculator

When a contractor payment needs TDS

A business that pays a contractor for work under a contract — and "contract" is read broadly, covering construction, catering, transport, manufacturing on job work, advertising, and most services — is generally required to deduct tax at source from the payment. The obligation sits under what was Section 194-C and now lives within the consolidated tax-deduction provisions of the Income-tax Act 2025. The payer deducts a small percentage, pays it to the government against the contractor's tax, and passes on the balance.

The obligation is not universal, though. It is triggered by two thresholds, and only when one of them is crossed does deduction become mandatory. A single payment or invoice of more than ₹30,000 triggers it on its own. Separately, once your total payments to that contractor for the whole financial year exceed ₹1,00,000, the obligation applies even if no single bill was large. The calculator tests both, because either one is enough.

Who must deduct matters too: businesses and entities generally, and individuals or HUFs only once they are large enough to be under a tax audit. A small individual paying a contractor for personal work usually has no obligation at all. But for any business of size, contractor TDS is routine compliance, and getting the trigger, rate and timing right is what this calculator is for.

The two thresholds, and the aggregate trap

The single-payment threshold is the easy one: a bill over ₹30,000 is caught, and TDS applies to that payment. The aggregate threshold is where businesses get caught out. Even if every individual bill is small — ₹20,000 here, ₹25,000 there — the moment your total payments to that one contractor cross ₹1,00,000 for the year, the obligation switches on for the whole amount, not just the payment that tipped it over.

That is the trap: the earlier small bills you had already paid in full, without deducting anything, are retrospectively brought into the net. You are then expected to deduct on the crossing payment enough to cover the shortfall on the earlier ones too, and to deduct on every payment thereafter. A business that pays a regular contractor in modest monthly instalments can sail past the ₹30,000 single test all year and still trip the ₹1,00,000 aggregate, owing TDS on the lot.

The practical defence is to track the running total for each contractor and start deducting as you approach ₹1,00,000, rather than discovering the breach at year-end. The calculator flags precisely when the aggregate rule, rather than a single large bill, is what triggered the obligation, so you know the earlier payments are implicated and can true up the shortfall before it becomes a default.

1% or 2%: the rate depends on the contractor

The rate is the most commonly mis-applied part of contractor TDS, because it depends not on you, the payer, but on who the contractor is. If the contractor is an individual or a Hindu Undivided Family, the rate is 1%. If the contractor is a company, a firm, a limited liability partnership, or any other kind of entity, the rate is 2%. Same work, same contract — but a sole proprietor is deducted at 1% and a private limited company at 2%.

Getting this wrong cuts both ways. Deduct 1% where 2% was due and you have under-deducted, exposing yourself to interest and a shortfall; deduct 2% from an individual where 1% was due and you have over-withheld, leaving the contractor to reclaim the excess. Neither is fatal, but both create friction and correction, and a careful payer checks the contractor's constitution before setting the rate. The calculator asks the contractor type up front and applies the matching rate, with a note reminding you to confirm you have the right one.

Note that these rates apply to the payment amount itself, and to the whole of it once a threshold is crossed, not merely the part above the threshold. There is no gentle ramp: cross ₹30,000 on a bill, or ₹1,00,000 for the year, and the rate applies to the full figure.

The 20% no-PAN penalty

The single most expensive avoidable error in contractor TDS is paying without the contractor's PAN. Where the payee has not given a valid PAN, the deduction rate is not 1% or 2% — it is a penal 20%. On a ₹5,00,000 payment to an individual that is the difference between ₹5,000 and ₹1,00,000 withheld, a twentyfold increase, and the calculator shows exactly what the missing PAN is costing in rupees.

The penal rate exists to force PAN collection, because without a PAN the government cannot match the TDS to the contractor's account, and the contractor cannot easily claim credit for it. So the missing PAN hurts everyone: you withhold far more, the contractor receives far less and struggles to reclaim it, and the paperwork multiplies. The fix is simple and entirely within your control — collect and verify the PAN before you make the first payment.

It is worth building PAN collection into your contractor onboarding rather than chasing it after a payment is due. A contractor who cannot or will not provide a PAN is telling you something, and the 20% deduction is the law's way of protecting the revenue in that situation. The calculator defaults to assuming the PAN is present and lets you toggle it off to see the penalty, precisely so the cost is visible before you pay.

What happens if you do not deduct

Because the payer is the deductor, the consequences of getting contractor TDS wrong fall on the business, not the contractor. Fail to deduct where you should have, or deduct and fail to deposit, and interest runs from the date the tax should have been deducted until it is finally paid, and a late-filing fee accrues on the TDS statement you did not file on time.

The sharpest consequence is the disallowance. Expenditure on which tax should have been deducted but was not can be disallowed to the extent of 30% when computing your business income — so a ₹5,00,000 contractor cost on which you skipped a ₹5,000 deduction can see ₹1,50,000 added back to your taxable profit until the default is cured. The tax on that disallowance dwarfs the TDS you were trying to avoid, which is why the compliance is worth getting right the first time.

The disallowance is generally reversed in the year you eventually deduct and deposit the tax, so the position can be cured, but only after inflating your profit and tax in the meantime. The lesson the calculator is built to teach is that deducting the right small percentage on time is far cheaper than any of the ways of getting it wrong.

Using this calculator well

Start with the two amounts — the year's total and the largest single bill — because between them they decide whether you must deduct at all. If you pay a contractor in instalments, keep the running total updated through the year, since the aggregate threshold is the one most likely to catch you unawares. When the total nears ₹1,00,000, treat the obligation as imminent and start deducting.

Then set the contractor type carefully, because the 1% versus 2% choice turns on it, and confirm the PAN is on record before you rely on the normal rate. If the calculator shows the penal 20%, the action is not to accept it but to get the PAN — the saving is immediate and large. Use the net figure to tell the contractor exactly what they will receive, so there is no dispute when the payment lands short of the invoice.

Finally, treat the rates and thresholds as the current defaults and confirm them for your period, as they are periodically revised, and remember this covers the deduction decision, not the mechanics of depositing the tax and filing the statement. It is a computation to tell you what to withhold and why — and to keep you clear of the disallowance that makes a missed deduction so much more expensive than the deduction itself.
