TDS on your flat purchase: Form 26QB is now Form 141, step by step

Almost every part of buying a flat is something you pay to somebody. This one is different: it is a payment you make on the seller's behalf, in your own name, using a form most people have never heard of, and if you skip it the government comes to you rather than to them. Buyers discover it late, usually when the sub-registrar's office or the bank mentions it in passing, and the ones who discover it a year late pay for the delay by the day.

What you need before you start#

Four things, and gathering them takes longer than the filing does.

Both PANs, verified. Yours and every seller's, spelled exactly as on the card. The whole system is PAN-based, and a mistyped seller PAN means the credit lands nowhere: the seller does not get it, you cannot easily reverse it, and the correction workflow is far slower than getting it right once.

The agreement value and the stamp duty value. TDS is computed on whichever is higher. Where a flat is being sold below the ready reckoner, and stamp duty is charged on the reckoner value anyway, the same higher figure drives this deduction.

The payment schedule. For an under-construction flat paid in instalments, you will file once per deduction, so you need the dates.

The property address as it appears in the agreement, because the form asks for it and a mismatch invites a query later.

The procedure#

The form changed this year, and most guidance has not caught up#

This is the part worth knowing before you search for help. For over a decade the property TDS form was Form 26QB and the certificate was Form 16B, and that is what almost every article, video and chartered accountant's checklist still says. From 1 April 2026, under the Income-tax Act, 2025, Form 26QB, 26QC, 26QD and 26QE were consolidated into a single PAN-based Form 141, with property transactions reported under its Schedule B, and the certificate reissued as Form 132.

Nothing about your obligation changed: still 1 percent, still Rs 50 lakh, still the buyer, still 30 days from month end. What changed is the label, and the practical consequence is narrow but real. If you are following a guide written before 2026, or a template your builder's office has been reusing, the form number in it is wrong. Read the portal, not the printout.

An analogy: withholding tax on a salary you are paying#

Every salaried person has watched an employer deduct tax before the money arrives and file it on their behalf. Nobody thinks the employee should have handled it, because the law puts the duty on whoever controls the payment. A flat purchase does the same thing and simply hands you the employer's role for one transaction. You are, for this purpose, the payer of a large sum to someone the government would rather not chase later, so it asks you to hold back a slice and account for it. Once the role is clear, the paperwork stops feeling arbitrary.

What it costs to be late#

The penalty structure is unusually mechanical, which is good news and bad news. Good, because there is no discretion and no argument to lose. Bad, because it accrues quietly from the day after the deadline, and buyers typically discover it at the next transaction rather than at the time.

Work one through. On a Rs 80 lakh flat the deduction is Rs 80,000. A buyer who never realised the obligation and files eleven months late pays the Rs 80,000 itself, roughly Rs 8,800 of interest at 1 percent a month, and a late fee that runs to the Rs 80,000 cap. A duty nobody told them about turns into about Rs 1.69 lakh, and the seller, who has not received a certificate, has been unable to claim credit for any of it.

Meera's second call to the CA#

Meera (illustrative, as our stories always are) bought a Rs 78 lakh resale flat in Thane and did everything the broker listed. Nobody listed this. Her seller mentioned Form 16B at the handover, she assumed it was the seller's paperwork, and eight months later a notice arrived quoting a section she had never read. The tax was never in dispute; she had simply paid it to the wrong person, in the sense that she had paid the whole 100 percent to the seller and none of it to the government.

What made it recoverable was that she had kept the agreement, the payment advice and the bank statement in one place, so the dates were provable and the interest could be computed exactly rather than estimated. What it cost her was the late fee, which no amount of good record-keeping avoids. Her second call to the CA opened with the sentence this article exists to prevent: "I did not know it was mine to do."

If you have already missed it#

Many people arrive at this subject late, so it is worth saying what the recovery looks like, because it is more ordinary than the notice makes it sound.

Nothing about a missed deduction is unfixable, and none of it requires a dispute. The obligation does not lapse, and it does not grow beyond the ceilings above: the late fee stops at the TDS amount, the interest accrues at a stated monthly rate, and once the filing is made and paid, the matter closes. There is no discretionary penalty waiting behind it for an ordinary buyer who simply did not know.

The sequence is the same as doing it on time, run late. Compute the deduction on the higher of consideration and stamp duty value. File and pay for the month in which the payment was actually made, not the current month, because the dates drive the interest and a convenient date is a wrong one. Then download the certificate and give it to the seller, which matters more than it looks: until they have it, they cannot claim credit for tax you have now paid in their name, and that is a live grievance between you and someone you may still need cooperation from.

Two practical notes. Where the purchase ran across several instalments, each one is its own filing with its own dates, so a late catch-up on an under-construction flat is several forms rather than one. And if the seller has already filed a return for that year without the credit, tell them once the certificate exists, because their revision is time-limited and depends on your paperwork.

The one situation that is not routine is discovering the seller was a non-resident. That is a different section at a materially higher rate, the shortfall is correspondingly larger, and it is worth professional advice rather than a portal form. Buying from an NRI seller sets out the section, the rate and the certificate that fixes it.

The checklist, in one place#

• Confirm the consideration is Rs 50 lakh or more, on the higher of price and stamp duty value.
• Confirm the seller is a resident. If not, stop and take advice, because the rate and section are different.
• Collect and verify every PAN, character by character.
• Deduct 1 percent at each payment, on the principal only.
• File Form 141 within 30 days of that month's end.
• Download Form 132 and give it to the seller without being asked.
• File the challan, the form and the certificate with the agreement, permanently.

Where this sits in the purchase#

TDS is one line in a sequence that also carries the booking amount, the agreement, stamp duty and the loan disbursement, and reading that sequence whole is what stops any single item surprising you: the money timeline of buying a flat lays it out in order. The certificate itself joins the permanent file described in the twelve documents to check before buying, and if you are weighing a resale against a new booking, note that the deduction applies to both: resale or new booking compares the rest.

That paperwork protects a purchase you have already decided on. The decision itself is a different question, and the one ReraGenie's Rs 499 buyer report answers for a Maharashtra project: the promoter's delivery record against promised dates, the project's own filing and complaint history, and the red flags on its current registration, assembled from the filings rather than from the sales office. If you are still choosing, start with the project's free page before you get as far as tax forms.

The one-line summary#

One percent, deducted by you, on anything from Rs 50 lakh up, filed as Form 141 within thirty days of the month's end and certified to the seller on Form 132: it is the one tax in the transaction that nobody will remind you about, and the only one that fines you by the day.
