Ready Reckoner Rate in Mumbai 2026: How It Affects Your Stamp Duty and Property Value

Most people buying a flat in Mumbai spend weeks comparing carpet areas, floor plans and possession dates. Then, days before registration, they find the stamp duty bill is higher than they budgeted for.

The reason is almost always the same. Stamp duty is not calculated on the price you negotiated. It is calculated on the ready reckoner rate, or on your agreement value, whichever of the two is higher.

Understanding that single rule can save you a very expensive surprise at the sub-registrar's office. Here is how the ready reckoner rate works in Mumbai, where to find yours, and everywhere else it quietly shows up in your costs.

What is a ready reckoner rate?

The ready reckoner rate is the minimum value the Maharashtra government assigns to a property for calculating stamp duty and registration charges.

Think of it as a government-set floor price. The state publishes rates for every locality, and often down to individual buildings and land parcels. No property can be registered below that value, whatever the buyer and seller agree between themselves.

Its official name is the Annual Statement of Rates, usually shortened to ASR. It is published by the Department of Registration and Stamps, Maharashtra — the body most people know as IGR Maharashtra. In everyday conversation it becomes the RR rate, the reckoner rate, or simply the ready reckoner.

Rates are published per square metre. Mumbai's are broken down by zone, sub-zone, village and survey or CTS number, which is why two buildings on the same road can carry different values.

Ready reckoner rate vs circle rate vs market rate

These terms get used interchangeably, and they shouldn't be.

So if you have been searching for the circle rate in Mumbai, what you want is the ready reckoner rate. Mumbai does not use "circle rate" officially. Only the label changes.

The market rate and the reckoner rate rarely match. Across most of Mumbai the market sits above the reckoner, sometimes far above it. In pockets with older stock or slow resale, the two can come close, and occasionally the reckoner sits higher.

That gap matters, and we will come back to it.

Who sets the rate, and when does it change?

The Maharashtra government reviews the Annual Statement of Rates each financial year. Any revision takes effect from 1 April.

Revisions are not uniform. The state sets different increases for different areas, and the Mumbai municipal area is usually treated separately from the rest of Maharashtra. In several recent years the government has chosen to leave rates unchanged altogether.

This is why you should never rely on a rate you saw quoted in a news article last year, or on a number a broker recites from memory. Check the current schedule for your specific property. The next section shows you how.

How to check your ready reckoner rate in Mumbai

You do not need a broker for this. The state publishes the rates and anyone can look them up.

1. Go to the IGR Maharashtra website at igrmaharashtra.gov.in.

2. Open the e-ASR section, listed under online services. It is sometimes labelled Annual Statement of Rates.

3. Select the year, then your district — Mumbai City or Mumbai Suburban.

4. Choose your taluka and village. Registration villages don't always match the locality names people use in conversation, so use the map view if you're unsure.

5. Find your property by CTS number or survey number. Your agreement or property card carries this.

6. Read the rate for your property type. Residential flats are listed separately from land, offices, shops and industrial units.

Two things worth knowing.

Your CTS number is the reliable identifier, not the building name or the postal address. If you don't have it, ask your developer or check the property card.

And the figure you find is a base rate for the location. Your flat's applicable value still needs adjustments applied on top.

What adjusts the rate for your specific flat

The published locality rate is a starting point, not the final answer. Several factors move the value applied to your unit.

Floor rise. Higher floors attract a loading that increases as you go up the building. The 22nd floor is valued above the 4th in the same tower.

Age of the building. Older construction receives a depreciation allowance, which brings the applicable value down.

Lift and building height. Buildings above a certain height without a lift are valued differently from those with one.

Property type. A ground-floor shop in your building carries a different rate from the flat above it.

Plot characteristics. For land, factors like plot size, shape and road access come into play.

This is why you can't lift a number from a news article and assume it applies to you. Two flats in the same tower, ten floors apart, can carry different reckoner values.

How the ready reckoner rate decides your stamp duty

Here is the rule that catches buyers out:

Stamp duty is charged on the higher of your agreement value or the ready reckoner value.

Negotiate below the reckoner and the government still charges duty on the reckoner value. Your negotiation saves you on price. It does not save you on duty.

Pay above the reckoner — common across Mumbai — and duty is charged on what you actually paid.

A worked example

Take a flat with a carpet area of 60 sq m.

The rate below is illustrative, chosen only to make the arithmetic easy to follow. Look up the real figure for your property using the steps above.

• Applicable reckoner rate: ₹2,00,000 per sq m *(illustrative)*

• Reckoner value: 60 × ₹2,00,000 = ₹1.20 crore

If you agree a price of ₹1.35 crore — the agreement value is higher, so duty applies to ₹1.35 crore.

If you negotiate hard and agree ₹1.10 crore — the reckoner value is higher, so duty applies to ₹1.20 crore. You pay duty on ₹10 lakh you never spent.

At Mumbai's rates, that difference is not trivial. It is also entirely predictable, if you check the reckoner before you commit rather than after.

What you'll actually pay

In Mumbai, stamp duty runs at 6% for most buyers — 5% stamp duty plus the 1% metro cess. Women buyers get a 1% concession, bringing it to 5%, subject to the conditions attached to that concession.

Registration charges are 1% of the value, capped at ₹30,000 for properties above ₹30 lakh, and ₹1,000 for those below.

Rates are stated as at the time of writing. Confirm the current position before you transact.

Four other things the ready reckoner rate affects

Most articles stop at stamp duty. The reckoner reaches further.

1. Your income tax

This is the one that costs people most, and the one they see coming least.

If a property changes hands well below its stamp duty value, the shortfall can be treated as income. The buyer can be taxed on the difference under Section 56(2)(x). The seller's capital gains can be computed on the higher stamp duty value under Sections 50C and 43CA. A tolerance of 10% applies, so small gaps are ignored.

Cross that 10% line, though, and a "bargain" purchase can trigger a tax demand on both sides of the deal — often larger than the discount that caused it. If a price is being quoted meaningfully below the reckoner value, take professional advice before you sign anything.

2. Your home loan

Lenders factor the reckoner value into how they assess the security. Where an agreement value sits far above the reckoner, some lenders take a more conservative view on the loan-to-value ratio. That raises the amount you need to fund from your own pocket.

3. Your BMC property tax

Mumbai's property tax uses a capital value system, and the ready reckoner rate feeds into that calculation. When reckoner rates rise, property tax tends to follow.

4. Your future capital gains

When you eventually sell, the stamp duty value at the time of that sale influences how your gains are computed. Today's reckoner isn't only a purchase cost. It stays attached to the asset for as long as you hold it.

What this means if you're buying in 2026

• Budget from the reckoner, not the brochure. Look up the reckoner value at shortlisting stage and calculate duty on the higher of the two figures. Not the week before registration.

• Ask about floor rise. If you're choosing between the 8th floor and the 24th, the reckoner value differs. It's a small factor beside the price difference, but it belongs in the comparison.

• Be wary of deals far below the reckoner. The tax exposure can exceed the discount.

• Watch the calendar. Rates change on 1 April. If your registration falls near that date, confirm which year's schedule applies.

• Remember what the reckoner doesn't tell you. It's an administrative minimum, not a valuation, and it says nothing about construction quality, approvals or whether the project will be delivered on time.

Frequently asked questions

What is the ready reckoner rate in simple terms?

It is the minimum value the Maharashtra government fixes for a property, used to calculate stamp duty and registration charges. No property can be registered below it.

Is the ready reckoner rate the same as the circle rate?

In substance, yes. "Circle rate" is the term used in Delhi and several north Indian states. Maharashtra calls the same thing the ready reckoner rate, published as the Annual Statement of Rates.

How often does the ready reckoner rate change in Maharashtra?

It is reviewed every financial year, with any revision effective from 1 April. In some years the government has left rates unchanged.

Can I pay stamp duty on my agreement value if it is lower than the reckoner rate?

No. Duty is charged on whichever is higher. If your agreement value falls below the reckoner value, duty is calculated on the reckoner value.

Where can I check the ready reckoner rate for my flat in Mumbai?

On the IGR Maharashtra website, igrmaharashtra.gov.in, through the e-ASR module. You'll need your district, village and CTS or survey number.

Does the ready reckoner rate reflect the market price?

Usually not. It's an administrative minimum rather than a valuation. Across most of Mumbai the market rate sits above the reckoner, though the gap varies widely by locality.

Do higher floors have a higher ready reckoner rate?

Effectively yes. Mumbai applies a floor-rise loading, so a higher floor carries a greater applicable value than a lower floor in the same building.

What happens if I buy well below the ready reckoner value?

Besides paying stamp duty on the reckoner value, a gap beyond the 10% tolerance can create income tax consequences for both buyer and seller. Get professional advice first.
