This is a dated log of what’s actually documented, not a general explainer — each item below is tied to a specific report and date so you can verify it yourself before relying on it.
Stamp duty: a rebate that came, was extended repeatedly, and was withdrawn
West Bengal’s 2% stamp duty cut and 10% circle rate (market value) reduction was announced in the state’s FY22 budget, per Indian Express and ET Realty (both 8 July 2021) — a relief measure aimed at boosting registrations. It didn’t expire on schedule the way many pandemic-era measures did; it got extended repeatedly:
- Extended to the end of 2022 (Times of India, 29 September 2022)
- Extended again to 31 January 2023 (Times of India, 30 December 2022) and, per Realty Plus Magazine’s report the same week, to March 2023
- Extended to 30 June 2023 (Times of India, 30 September 2023 report referencing the extension)
- Extended once more to June 2024 (ET Realty, 30 September 2023)
That run ended in mid-2024: the West Bengal government withdrew the 2% stamp duty and 10% circle rate relief effective around 1–2 July 2024, per The Economic Times (“Bengal government withdraws 2% stamp duty, 10% circle rate relief for real estate sector,” 1 July 2024) and Hindustan Times. The effect showed up quickly in the data — Hindustan Times, citing Knight Frank India, reported that Kolkata property registrations fell 13% year-on-year in July 2024 after the rebate was discontinued (21 August 2024).
If you’re budgeting for a purchase now: don’t assume the 2021-era 2% rebate — it’s gone as of July 2024, per the sources above. Confirm the current stamp duty and circle-rate-based valuation directly with your Sub-Registrar office or a property lawyer before finalizing numbers.
Circle rates: Kolkata’s first revision in seven years (September 2025)
More than a year after the rebate ended, Kolkata got a separate, bigger shock: its first property circle rate revision in seven years, reported by The Times of India (“First property circle rate hike for Kolkata in seven years to push up registration fee, stamp duty,” 18 September 2025) and Moneycontrol, which reported increases running up to 90% in some areas (“Kolkata property buyers face sticker shock as circle rates surge up to 90%,” also 18 September 2025).
Two follow-on data points worth knowing:
- Registrations spiked ahead of the change — Times of India (19 September 2025) reported August 2025 home registrations in Kolkata up 15% year-on-year and 33% over July, consistent with buyers rushing to register before the new, higher rates applied.
- The state walked back part of the increase for some localities shortly after — reported by both Times of India (“Relief for city homebuyers: State eases circle rates in select areas,” 27 September 2025) and Realty Today (30 September 2025) — though we couldn’t independently verify the exact areas or revised percentages from the material available; check directly with the Directorate of Registration & Stamp Revenue for the current rate on a specific plot or flat.
Practical takeaway: circle rate is the floor value stamp duty gets calculated on — a higher circle rate means a higher minimum stamp duty bill even if your actual sale price hasn’t moved. If you’re transacting in Kolkata, verify the current circle rate for the exact locality before estimating registration cost; the 7-years-stale number you might find in an older guide (including, potentially, older pages on sites like this one) is no longer reliable after September 2025.
WBHIRA / WBRERA: still worth watching, not still in crisis
We’ve covered the fuller history separately (see our guide to checking WBRERA registered projects), but the short version for a news roundup: West Bengal’s own real estate law, WBHIRA, was struck down by the Supreme Court on 4 May 2021, the state was slow to respond, and a functioning West Bengal RERA authority only became operational from around December 2022 (per ET Realty, 17 December 2022), with the Supreme Court confirming on 17 May 2023 that pending WBHIRA complaints transfer to RERA (SCC Online / Times of India, 17 May 2023). The appellate tribunal, WBREAT, has stayed active since — Calcutta High Court records show WBREAT appeals as recently as April 2025, and trade press (LiveLaw) reported WBREAT rulings against developers into January 2026. We did not find evidence of a further legislative change specific to 2025-2026 beyond this now-settled operational arrangement — if the framework changes again, that’s a story for a future update, not this one.
Banglarbhumi and land records: nothing solid enough to report
We looked for a specific, dated 2024-2026 update to Banglarbhumi (the state’s land record portal) or its e-mutation process — a new feature, a policy change, a digitization milestone — and came up short on two separate research passes. One lead (a single-source reference to an “automated mutation” announcement) couldn’t be corroborated against an independent outlet, so we’re leaving it out rather than repeating an unverified claim. If Banglarbhumi has changed in a way that matters to your transaction, the current process is what’s shown on banglarbhumi.gov.in or at your local BL&LRO office right now — not what any article, including this one, says about it.
Metro infrastructure: a big single day, 22 August 2025
Kolkata Metro had an unusually large infrastructure day on 22 August 2025, when the Prime Minister inaugurated three separate pieces of the network at once, per Hindustan Times (“PM Modi inaugurates Kolkata metro corridors; experts say real estate markets to gain from airport, suburban connectivity,” 22 August 2025):
- The final gap between Sealdah and Esplanade closed, joining what had been two separate Green Line segments into one continuous route running from Salt Lake Sector V all the way to Howrah Maidan.
- The Orange Line extended from Hemanta Mukhopadhyay to Beleghata.
- The Yellow Line’s first phase opened between Noapara and Jai Hind (Biman Bandar) — Kolkata’s first direct metro connection to Netaji Subhas Chandra Bose International Airport.
Separately, the Purple Line’s planned extension beyond Majerhat was redirected to terminate at Eden Gardens rather than Esplanade — sanctioned in March 2025, with an estimated completion around May 2028, meaning it’s a multi-year story rather than a near-term one. See our investment-analysis piece on West Bengal infrastructure corridors for what these openings mean area-by-area.
What we couldn’t verify, and left out
In the interest of not padding this roundup, a few threads we looked into but couldn’t confirm with a specific, dated, independently-corroborated source: any 2024-2026 update to Banglarbhumi or the e-mutation process (see above), and the precise localities and percentages in September 2025’s circle-rate relief order. We’d rather flag the gap than guess at the number.
This roundup reflects publicly reported news as of the dates cited and is not legal, tax, or investment advice — figures like circle rates and stamp duty percentages change by government notification, and the specific rate applicable to your transaction should be confirmed with the Directorate of Registration & Stamp Revenue or a property lawyer.
