Stamp duty in India:
what the rate is applied to, and what comes on top

What stamp duty is actually charged on

Stamp duty is a tax the state collects when a property document, such as a sale deed, is made legally valid. In practice it is a cheque you write before the registrar will register your purchase, and it is usually one of the largest costs after the price itself.

The calculation looks simple: a value multiplied by a rate. The trap is that the value is not always the price you negotiated. Most states also publish a minimum rate for land and built-up space in each locality. It goes by different names such as circle rate, ready reckoner rate or guidance value. If your agreed price is lower than that benchmark, the benchmark is normally used instead.

The rate itself is set by each state and can differ for urban and rural property, for men, women or joint buyers, for a sale versus a gift, and between a residential flat and a commercial shop. Some states add a surcharge, cess or local body duty on top. Because these rules are revised through state budgets and notifications, treat every percentage in this page as an example and confirm the live figure with the sub-registrar's office or the state revenue department website.

The formula behind the amount

Two steps are involved. First decide the dutiable value, then multiply by the rate that applies to your transaction.

Because rates are stated as a percentage, shift the decimal point by two places before multiplying: 5% is 0.05, 6.5% is 0.065.

A worked example with a ₹50 lakh flat

Take a flat bought for ₹50,00,000 in a state where the applicable rate for your category is, for the sake of arithmetic, 5%. The government-assessed value of the flat is lower than the price, so the price is the dutiable value.

Now flip the situation. Suppose the same flat is assessed at ₹56,00,000 although the builder is selling it for ₹50,00,000. The state does not accept the lower figure.

Duty, registration fee and the extras

Buyers often hear both terms used as if they were one. They are different charges with different rules.

• Stamp duty: the tax on the document, as a percentage of the dutiable value.
• Registration fee: a separate charge for entering the document in government records. Some states cap it at a fixed rupee amount, others use a percentage.
• Surcharge or cess: an add-on in some states or cities, such as a metro or local body levy.
• Other costs: GST on under-construction property, brokerage, legal verification and society transfer fees are not stamp duty at all, although they belong in the same budget.

Keep the registration estimate separate in your spreadsheet. If the state changes only the registration fee in a budget, you can update that one line instead of re-deriving everything.

How buyer category and property type move the number

Many states reduce the duty rate, or the amount of duty, for women buyers, for senior citizens or for first-time buyers, and some apply different rates to a joint purchase. Others have temporary concessions linked to a ready-reckoner revision or an economic stimulus. These schemes begin and end by government order, so a concession mentioned in a news article from last year may no longer exist.

Use these as questions for the registrar rather than as answers. A flat in one city and an identical flat across a state line can carry quite different duty.

Checking the figure before you sign

A quick estimate is useful for choosing a budget, but the amount actually payable is printed on the document or challan. The gap between the two usually comes from three places: the area, the benchmark rate for the exact locality and the category of buyer.

1. 1Ask the seller for the carpet, built-up or super built-up area that the deed will state, and note which one the state uses to apply its benchmark.
2. 2Find the current benchmark for your locality and property type on the state registration portal, or ask the sub-registrar. Rates are often listed by ward, street or survey number.
3. 3Multiply benchmark by area to get the government-assessed value, then compare it with the agreement price.
4. 4Take the larger figure, apply the rate for your buyer category, and add registration and any local surcharge from the same official schedule.
5. 5Keep a printout or screenshot of the schedule you used, along with its date, in case the payable amount is queried.

Many states also let you pay duty online through an e-stamping or e-payment system and print the receipt. The portal calculates the figure from the data you enter, so it is worth running your numbers by hand first. A misplaced decimal in the area or an incorrect property category is a common reason for paying more, or for being asked to pay a deficit later with a penalty.

If the property is under construction, ask whether duty is payable on the builder agreement now or on a later conveyance. Practices differ between states, and the answer decides when the cash is needed.

Mistakes that make the estimate wrong

• Applying the rate to the price when the government value is higher.
• Forgetting that duty is computed on the property value, not on the loan amount.
• Using an old rate quoted by an agent or an older article.
• Leaving out registration, cess and legal fees, which can add up to a noticeable extra sum.
• Mixing area units: assessed values are quoted per square metre or per square foot, and the wrong unit makes the dutiable value badly off.
