    When a Bangalore RERA developer who registered an apartment project at a specific price and executed registered sale agreements with allottees at that price subsequently demands additional amounts from the allottees -- claiming that the Karnataka government revised the guidance value for the area between the date of the original allotment and the date of possession, which increased the stamp duty cost for the developer's project and which the developer now wants the allottees to share through an increased flat price -- the demand is an unauthorized price revision that violates RERA Section 13's prohibition on collecting amounts beyond the registered sale agreement's specified consideration.

    Does a Guidance Value Revision Justify an Increased Flat Price?

    The guidance value revision affects the stamp duty payable on the registered sale deed between the developer and the allottee -- the buyer pays stamp duty based on the guidance value (or the sale price, whichever is higher) at the time the sale deed is registered. If the guidance value increased between allotment and possession, the allottee pays higher stamp duty on the sale deed registration at possession. However, the stamp duty increase is the allottee's own cost of registration -- it is not an increase in the flat's sale price.

    The developer may argue that the guidance value revision also increased the developer's own land cost or construction cost -- but these are costs the developer bore when acquiring the land or when incurring construction expenses, not at the time of sale deed registration. A guidance value revision between allotment and possession does not change the developer's land acquisition cost (which was fixed at the time of purchase) or the registered sale agreement's stated consideration (which was fixed at the time of allotment).

    Developer Price Revision Claim

    RERA Section 13 Position

    Allottee's Stamp Duty Impact

    Allottee's Response

    Developer demands increased flat price because guidance value rose -- no specific clause in sale agreement allows price revision for guidance value changes

    Unauthorized -- RERA Section 13 prohibits collection beyond the registered agreement -- guidance value revision is not a contracted price revision trigger

    The allottee pays higher stamp duty at registration (based on the new higher guidance value) -- but this is not an increase in the flat price

    Refuse the additional demand -- cite RERA Section 13 -- the flat price was fixed at allotment

    Developer argues the stamp duty increase means the total cost of ownership increased -- demands the allottee share the "increased cost"

    The stamp duty is the allottee's cost -- not the developer's. The developer has no right to demand reimbursement of the allottee's own statutory cost

    The allottee's stamp duty increase is their own expense -- the developer has no role in it beyond handing over the sale deed for registration

    Reject the demand -- the stamp duty is a statutory obligation of the buyer, not a price revision

    Sale agreement specifically includes a clause: "price subject to revision based on government guidance value changes"

    If such a clause was in the registered sale agreement, the revision may be contractually valid -- but K-RERA adjudicating officers have generally held such clauses to be against RERA's spirit

    The clause is in the agreement -- but the RERA framework's protection may override it

    Consult a property lawyer -- if the clause violates RERA's intent, file a K-RERA complaint challenging it

    Developer demands extra stamp duty top-up from the allottee at the time of registration claiming the developer overpaid earlier

    The stamp duty is the buyer's obligation -- if the developer paid it on the buyer's behalf at an earlier date, they can seek reimbursement of the actual government stamp duty amount -- but not a higher amount

    Limited to the actual stamp duty differential if the developer genuinely paid it -- cannot be inflated

    Pay only the actual stamp duty differential if the developer paid it first -- reject any inflated demand

    How Should the Allottee Respond to a Developer's Post-Allotment Price Demand?

    • Step 1: Review the registered sale agreement for the specific price agreed and any price revision clauses -- confirm whether a guidance value revision was a contracted price revision trigger.
    • Step 2: If no price revision clause exists, send a formal written response rejecting the demand -- citing RERA Section 13's prohibition on collection beyond the registered agreement.
    • Step 3: Confirm the actual stamp duty payable at the time of registration (based on the current guidance value) -- the allottee owes the actual stamp duty but not an inflated price revision demanded by the developer.
    • Step 4: File a K-RERA complaint under Section 13 if the developer insists on the unauthorized demand or withholds possession pending payment of the increased price.
    • Step 5: Have a property lawyer review the specific demand letter and the sale agreement's price terms to confirm the legal position.

    Q1. Can a developer revise the flat price during the project's construction period?

    Under RERA, the developer cannot revise the flat price above what was specified in the registered sale agreement without the allottee's written consent. A price revision clause in the sale agreement that links the price to external factors (like guidance value) must have been disclosed in the K-RERA registration and the registered sale agreement -- it cannot be introduced after the fact.

    Q2. Does the guidance value revision affect the allottee's capital gains when they later resell?

    When the allottee eventually resells the flat, the Section 50C analysis (Page 779) applies -- the capital gains are computed on the higher of the stated sale price and the guidance value at the time of the resale. The guidance value at the time of the original purchase (allotment to the allottee) is the allottee's cost of acquisition for capital gains purposes -- a higher guidance value at the time of original acquisition (because the developer demanded an increased price based on the revised guidance value) would increase the allottee's cost of acquisition and reduce the future capital gains.

    Q3. Can a developer demand stamp duty top-up from the allottee if the developer originally collected and paid the stamp duty on the allottee's behalf?

    If the developer collected the stamp duty from the allottee at the time of allotment (based on the guidance value at that time) and then registered the sale deed later when the guidance value was higher, the actual stamp duty payable on registration is higher than what was collected. The developer can legitimately ask the allottee to pay the additional stamp duty differential -- the actual government stamp duty increase is the allottee's legitimate obligation. A demand for more than the actual stamp duty differential is unauthorized.

    Q4. What if the developer claims the guidance value revision also increased the project's development charges payable to BBMP or BDA?

    Development charges payable to BBMP or BDA are the developer's cost of developing the project -- they are absorbed in the flat price that the developer set. A post-allotment increase in development charges does not entitle the developer to increase the flat price above the registered agreement -- unless a specific clause in the agreement allows for development charge pass-through. Most standard RERA agreements do not include such a clause.

    Q5. Can the allottee withhold the balance payment if the developer is demanding an unauthorized increase?

    An allottee who refuses to pay an unauthorized price revision and thereby withholds the balance payment creates a complicated situation -- the developer may treat the withheld balance as a default and attempt to cancel the allotment. The safer approach is: pay the legitimate balance payment on schedule; separately refuse the additional unauthorized demand in writing; and file a K-RERA complaint for the unauthorized demand -- rather than withholding the entire balance.

    Q6. Is a guidance value revision a force majeure event under RERA?

    No -- a guidance value revision by the government is not an unforeseeable event beyond the developer's control. Guidance value revisions happen regularly (typically annually or biannually) and are a known feature of Karnataka's property market. A developer who claims a guidance value revision is a force majeure event would generally not succeed in that argument before a K-RERA adjudicating officer.

    Q7. What if the guidance value decreased between allotment and possession -- does the allottee get a price reduction?

    A guidance value decrease would reduce the stamp duty payable at registration -- benefiting the allottee. It does not reduce the flat's registered sale price (which was fixed at allotment). The guidance value affects the stamp duty calculation, not the contractual sale price in either direction.

    Q8. Can the developer demand the allottee pay for BBMP betterment charges that were levied after the allotment?

    BBMP betterment charges levied on the developer's project after the allotment are the developer's cost -- not an allottee's obligation unless the sale agreement specifically provides for betterment charge pass-through. A developer who demands the allottee pay the betterment charges without a contractual basis is making an unauthorized demand under RERA Section 13.

    Q9. What if the developer increased the GST charge based on the guidance value revision?

    GST on under-construction flats is calculated on the total consideration paid to the developer -- not on the guidance value. A guidance value revision does not change the GST calculation. If the developer increased the GST demand based on the guidance value revision, the demand is both factually incorrect (the GST rate is applied to the sale price, not the guidance value) and potentially unauthorized.

    Q10. How does Legal Brigade assist allottees facing post-allotment price revision demands?

    Legal Brigade reviews the registered sale agreement for any price revision clause, confirms the RERA Section 13 position on the specific demand, calculates the legitimate stamp duty differential (if any), drafts the formal rejection of the unauthorized portion, files the K-RERA Section 13 complaint if the developer withholds possession and advises on whether to pay the legitimate balance while separately disputing the unauthorized revision.

    Your Bangalore developer is demanding an extra Rs 3-10 lakh because the guidance value in your area increased since you signed the sale agreement -- arguing you must share the higher stamp duty cost? Legal Brigade confirms this is an unauthorized RERA Section 13 demand and files the K-RERA complaint.

    Frequently Asked Questions

    Can a developer revise the flat price after the sale agreement is registered? ▾

    Under RERA Section 13, a developer cannot increase the flat price beyond what is specified in the registered sale agreement without the buyer's written consent. Any price revision clause must be disclosed in the original agreement to be potentially valid.

    Does a guidance value hike justify an increase in the flat's sale price? ▾

    No, a guidance value revision increases the stamp duty payable to the government but does not change the developer's land or construction costs. The developer has no right to demand a higher price for the property itself based on this statutory change.

    What should I do if a developer demands extra money for stamp duty? ▾

    If the developer paid the stamp duty on your behalf and the government rate increased, they can seek reimbursement for the actual differential amount. However, you should reject any demand that exceeds the actual statutory government cost.

    How does RERA protect against unauthorized price demands during construction? ▾

    RERA prohibits the collection of amounts beyond the registered sale agreement's specified consideration. If a developer withholds possession or demands unauthorized price hikes, buyers can file a formal complaint with K-RERA under Section 13.
