Priya and Arjun had agreed on everything about the Pune 2BHK except one line on the draft agreement, the one that names the buyers, and they had not realised it was a decision until the promoter's office asked for it. Joint names felt fair. Priya's name alone saved stamp duty. Arjun's income carried more of the loan. Each option was right about something, and on a Rs 90 lakh flat the difference between them was measured in lakhs over the life of the loan.
Key takeaways
- The names on the agreement fix the stamp duty, the loan eligibility, each person's tax deductions, and who must sign when the flat is sold.
- Maharashtra's 1 percent women's stamp duty concession applies only when every buyer on the document is a woman; one male co-owner removes it for the whole document.
- Under the old tax regime, each co-owner who is also a co-borrower and pays the EMI can deduct up to Rs 2 lakh of interest a year on a self-occupied flat; the new regime allows none.
- Joint ownership does not make the survivor the owner of the whole flat. Each share passes under its owner's will or succession law, and selling the whole flat needs every co-owner's signature.
- In ANAROCK's consumer sentiment survey for H2 2025, 61 percent of women buyers were looking at homes priced above Rs 90 lakh.
The four structures, defined honestly
One name. The simplest document and the simplest future sale. Only that person can claim the tax deductions, and only their income supports the loan, unless the other signs as a co-borrower without being an owner, which helps the loan but not the tax.
Joint names, equal or stated shares. The fairest-feeling option and usually the best for the loan, because the bank can count both incomes. Under the old tax regime it can double the available interest deduction. It also means two signatures on every future decision.
All-women names. One woman alone, or several women together, such as a buyer and her mother. This is the only structure that earns the 1 percent stamp duty concession. It helps only if the family's finances genuinely support the woman or women named, because the ownership is real, not a label.
Her name alone, with the husband as co-borrower. A woman owns and both borrow. It keeps the stamp duty concession while letting the lender count both incomes, at the cost of the husband claiming no ownership-linked tax deduction. Lenders' policies on non-owner co-borrowers vary, so ask before you plan around it.
What each choice costs
| Question | One name | Joint, man and woman | All-women names |
|---|---|---|---|
| Stamp duty in Pune | 7 percent for a man, 6 percent for a woman | 7 percent | 6 percent |
| Loan eligibility | One income, unless the other is a co-borrower | Both incomes as co-borrowers | The women's incomes, plus any co-borrower the lender accepts |
| Interest deduction, old regime, self-occupied | Up to Rs 2 lakh | Up to Rs 2 lakh each, if both are co-borrowers paying the EMI | Up to Rs 2 lakh for each woman owner who is a co-borrower |
| Interest deduction, new regime | None | None | None |
| Selling later | One signature | Every co-owner signs | Every co-owner signs |
| If an owner dies | Passes under their will or succession | Their share passes under their will or succession, not automatically to the other | Same, share by share |
What the stamp duty difference is in rupees
The concession is 1 percent of the property value, and it is all or nothing. On a Rs 90 lakh flat in Pune, where a man pays 7 percent and a woman 6 percent because a local body tax and a metro cess stack on the 5 percent duty, the names decide the following.
Source: Maharashtra stamp duty of 7 percent for male buyers and 6 percent for all-women buyers in Pune, and 1 percent registration capped at Rs 30,000, as reported for 2026; confirm against IGR Maharashtra before payment.
Rs 90,000, paid once, in the same weeks as the booking amount and the down payment. The rates behind it, and the Mumbai equivalents, are set out in stamp duty and registration charges. One constraint made this concession awkward when it was introduced in 2021: it came with a 15-year restriction on selling to a man, and that condition was removed in May 2023, which makes an all-women registration a cleaner choice than it first was.
What the tax difference is, and for whom
The tax side is larger than the stamp duty over time and narrower in who can use it.
Under the old tax regime, interest on a loan for a self-occupied flat is deductible up to Rs 2 lakh a year per person, now under section 22 of the Income-tax Act 2025, which replaced section 24 of the 1961 Act from April 2026. Principal repayment counts towards the old regime's separate Rs 1.5 lakh savings deduction, which it shares with provident fund, life insurance and similar. Each co-owner who is also a co-borrower and actually pays their share of the EMI can claim both, so two co-owners can deduct up to Rs 4 lakh of interest between them where one owner alone could deduct Rs 2 lakh.
On a Rs 72 lakh loan at 8 percent, interest in the first full year of repayment is about Rs 5.7 lakh, comfortably above either limit, so once the flat is complete the second owner's deduction is fully usable. On a flat still under construction, interest paid before completion is deductible only from the year construction is completed, in five equal instalments within the same Rs 2 lakh limit, and that limit falls to Rs 30,000 if construction is not completed within five years from the end of the tax year in which the loan was taken. What the deduction is worth depends on each person's tax slab.
The qualification that changes the answer for many couples is the regime. The new tax regime, now the default, allows no interest deduction at all on a self-occupied flat. A couple who both file under it gain nothing in tax from joint names, and should decide on stamp duty, the loan and control alone. A couple where one files under the old regime should put that person on the title and the loan.
An analogy: a joint bank account with two signatures required
A joint account where both must sign every cheque is fair and safe, and it is also slow: nothing moves without both people, and if one is abroad, ill or no longer speaking to the other, nothing moves at all.
Joint ownership of a flat works like the two-signature account. It is right for a couple building a shared life, and it is worth choosing knowingly, because every future sale, mortgage or redevelopment consent needs every name on the document.
Priya and Arjun decide
Priya and Arjun (illustrative, as our stories always are) worked through it with numbers rather than instinct. The loan needed both incomes. Arjun filed under the old regime because of other deductions; Priya had moved to the new one. That settled the tax question: Arjun's name on the title and the loan secured the deduction, while Priya's added nothing in tax. Joint names cost Rs 90,000 more in stamp duty than Priya alone, but Priya alone would have lost Arjun's interest deduction, worth more than that over the first few years after possession.
They registered jointly, stated their shares in the agreement to match what each was paying, and made wills the same month, because the one thing joint names did not do was decide what happens to either share on a death. Names and numbers in this story are illustrative.
The framework: five questions that decide it
- Whose income does the loan need? If the lender needs both, both will usually be co-borrowers, and the question becomes whether both should also be owners.
- Which tax regime does each person file under? The joint structure's tax advantage exists only for a co-owner in the old regime.
- Is an all-women registration genuine for your family? The 1 percent saving is real only if the ownership is.
- Who needs to be able to sell or mortgage it later? More names mean more signatures, and more ways for a future decision to stall.
- Have you made wills? Joint names do not pass a share to the survivor. Nomination is not a will explains why the society's nomination does not settle it either.
Every buyer named on the agreement also has obligations on the purchase itself. On a flat of Rs 50 lakh or more, each co-buyer deducts TDS on their own share of the price and files it separately, the steps covered in TDS on your flat purchase. Two names means two filings.
Where the filings come in
Whichever names go on the agreement, they will be signing against one promoter's record, and that record is the same for every structure. For any covered Maharashtra project, the Rs 499 ReraGenie buyer report reads it: the promoter's other registrations against their original and current completion dates, this project's extension history with the reasons filed, and its complaints and litigation with case numbers. Joint owners share the risk of a late or stalled project equally, so it is worth both reading it. Start with the project's free page, and read registration day at the sub-registrar for what each named buyer needs to bring.
The one-line summary
The names on the agreement set the stamp duty, the loan, two people's tax deductions and every future signature: all-women names save 1 percent of the price, joint names can double the old regime's interest deduction, the new regime cancels that advantage, and neither structure replaces a will.
Methodology and sources
- Stamp duty and registration: Maharashtra rates of 7 percent for male buyers and 6 percent for all-women buyers in Pune, 6 and 5 percent in Mumbai, with registration at 1 percent capped at Rs 30,000, as reported for 2026; the removal of the 15-year condition on the women's concession, May 2023.
- Tax: section 22 of the Income-tax Act 2025, in force from 1 April 2026, for the Rs 2 lakh interest limit on a self-occupied flat under the old regime, and the Rs 30,000 limit where construction overruns five years; the Rs 1.5 lakh principal limit is the old regime's general savings deduction, the successor to section 80C, not section 22. The first-year interest figure is ReraGenie arithmetic on a Rs 72 lakh loan at 8 percent over 20 years. This is general information, not tax advice.
