Most Indian apartment buyers do not realise that the legal obligation to deduct and deposit TDS on a property purchase sits with them — not the builder, not the seller, not the lawyer. Miss the 30-day deadline, pay the wrong amount, or get the seller PAN wrong, and an Income Tax Department notice lands within 12-18 months. Penalties stack at ₹200 per day plus 1% interest per month.
This is the most expensive piece of paperwork most home buyers ignore. Here is exactly how it works in 2026.
The Rule: Section 194-IA in Plain English
If you buy any immovable property (apartment, villa, plot, commercial unit) where the sale consideration is ₹50 lakh or more, you must deduct 1% TDS on the full sale value — not just on the amount above ₹50 lakh — and deposit it with the Income Tax Department within 30 days of the end of the month in which payment is made.
So on a ₹85 lakh apartment, you deduct ₹85,000 from your payment to the seller and deposit it with the IT department. The seller receives ₹84,15,000. You keep the proof of deposit (Form 16B) and hand it to the seller as their TDS certificate.
The rule applies to every payment instalment. If you are buying an under-construction flat and paying across 8 stages, you deduct 1% on each payment and file Form 26QB each time. Eight payments, eight Form 26QB filings.
The Three Forms You Must Know
| Form | What It Is | Who Files | Deadline |
|---|---|---|---|
| Form 26QB | TDS challan-cum-statement | Buyer | Within 30 days of end of month of payment |
| Form 16B | TDS certificate (downloaded from TRACES) | Buyer downloads, hands to seller | Within 15 days of Form 26QB filing |
| Form 26AS | Annual tax statement (TDS credit appears here for the seller) | Auto-generated | Visible in seller IT portal |
Where you actually file Form 26QB
On the Income Tax e-filing portal (incometax.gov.in) → e-Pay Tax → Form 26QB. You will need:
- Your PAN and the seller PAN (both mandatory)
- Property address and the exact sale consideration on the agreement
- Date of agreement and date of payment
- Amount paid in this instalment and TDS amount (1% of that instalment)
Payment is via net banking. The challan is generated immediately. Form 16B becomes available on TRACES (tdscpc.gov.in) roughly 7 days later — download it as a PDF and hand it to the seller.
The 5 Mistakes That Trigger IT Notices
- Wrong seller PAN. Buyers copy the PAN from the agreement without verifying it on the IT portal. If it is wrong or inoperative (not Aadhaar-linked under the 2023 rules), the TDS credit does not reach the seller — and both parties get notices. Verify the PAN on incometax.gov.in → Quick Links → Verify PAN before you file.
- Treating each co-buyer separately on a joint purchase. If two of you buy a ₹90 lakh flat at 50:50 (₹45 lakh each), some buyers assume the ₹50 lakh threshold does not apply because each share is below it. Wrong. The threshold tests total property value, not your individual share. Each co-buyer files a separate Form 26QB for their share. Each deducts 1% on their ₹45 lakh.
- Forgetting NRI sellers fall under Section 195, not 194-IA. If the seller is a Non-Resident Indian, the rate is not 1%. It can be 20%, 22.88%, or 23.92% (with surcharge and cess) depending on holding period and capital gains treatment. The form is 27Q, not 26QB. Get a CA involved before the first payment — getting this wrong costs lakhs.
- Deducting on the builder demand letter date instead of the payment date. The 30-day clock starts on the date you actually transfer money, not the date the builder raised the demand. A demand raised on 25 March and paid on 3 April triggers a 30 April Form 26QB deadline — not a 30 March one.
- Not deducting on PLC, parking and amenity charges. Brokers often tell buyers these are "separate" and do not count toward the ₹50 lakh threshold. They do. Section 194-IA defines sale consideration as the full agreement value, including preferential location charges, floor rise, parking allotment, and club membership. The IT department reads the agreement, not the broker pitch.
For Under-Construction Buyers: The Instalment Trap
If you have signed up for an under-construction apartment with 8-12 payment milestones, you owe a Form 26QB on each. Filing them all at the end of the construction period is non-compliance — the late fee is ₹200 per day per filing. A buyer who delays eight filings by a year owes ₹5.84 lakh in late fees alone, before interest.
Set a calendar reminder for the 25th of every month. That gives you 5 days to file Form 26QB for any payment made in the previous month — comfortably inside the 30-day window.
Joint Ownership: The Equal-Share Default
If two buyers are on the agreement and the agreement does not specify ownership share, the IT department assumes 50:50. Both buyers file Form 26QB for their 50% share. If the actual contribution is unequal (one paid 70%, the other 30%), declare this explicitly in the agreement — otherwise the IT default applies, and the spouse who did not actually pay may face questions on source-of-funds during a future scrutiny.
The Bottom Line
TDS on property purchase is not optional, and the buyer carries the full legal liability. The cost of compliance is roughly one hour per payment instalment. The cost of non-compliance is ₹200 per day, 1% interest per month, and a notice that can drag on for two years.
Before you sign any sale agreement: verify the seller PAN on the IT portal, set calendar reminders for every payment milestone, and bookmark incometax.gov.in. If the seller is an NRI or the property is held jointly with unequal contribution, talk to a CA before the first payment.
