Project Delay Under RERA Section 18: Refunds, Interest, and Compensation

Section 18 of the Real Estate (Regulation and Development) Act, 2016 is the provision that has done more than any other to change the economics of delay in Indian real estate. Before RERA, a delayed project meant a difficult allottee call, a few angry emails and perhaps a consumer forum complaint that would take years. After RERA, a delayed project means a statutory obligation to refund or pay monthly interest at a prescribed rate, often enforceable within six months of the first complaint, with consolidated allottee proceedings multiplying the financial impact.

For developers, Section 18 is the single largest financial risk in the RERA Act. It is not a penalty; it is a civil remedy. Unlike Section 59 or Section 61 penalties, Section 18 liability is not capped at a percentage of project cost — it is calculated per allottee, per month, on all amounts paid. A ten-month delay on a 200-apartment project can generate tens of crores of Section 18 exposure even before considering Section 61 penalties or consumer forum compensation.

This guide walks through what Section 18 actually requires, how state authorities have interpreted it, where the defence strategies work and where they do not, and how developers should provision for the exposure. It is written for project heads, CFOs and developer principals.

1. The Statutory Text

Section 18(1) states: "If the promoter fails to complete or is unable to give possession of an apartment, plot or building, in accordance with the terms of the agreement for sale or, as the case may be, duly completed by the date specified therein; or due to discontinuance of his business as a developer on account of suspension or revocation of the registration under this Act or for any other reason, he shall be liable on demand to the allottees, in case the allottee wishes to withdraw from the project, without prejudice to any other remedy available, to return the amount received by him in respect of that apartment, plot, building, as the case may be, with interest at such rate as may be prescribed in this behalf including compensation in the manner as provided under this Act: Provided that where an allottee does not intend to withdraw from the project, he shall be paid, by the promoter, interest for every month of delay, till the handing over of the possession, at such rate as may be prescribed."

Two clean remedies emerge:

• Refund with interest if the allottee withdraws.
• Monthly interest for delay if the allottee continues.

The allottee elects; the promoter must honour.

2. The Prescribed Interest Rate

State rules uniformly prescribe the interest rate as the State Bank of India's highest marginal cost of lending rate (MCLR) plus two percent. The MCLR is published monthly by SBI. For enforcement purposes, the rate applicable is typically:

• The rate in force on the date of the order, or
• The rate in force on the date of default, as specified in the particular state rule.

As of 2026, SBI's 1-year MCLR hovers in the 9.0 to 9.5 percent range; with the two-percent addition, the prescribed rate is typically between 11 and 12 percent per annum.

3. How Interest Is Actually Calculated

For an allottee who has paid ₹80 lakh over three years on a ₹1 crore apartment and experiences a ten-month delay:

• Interest is computed on each instalment from the date it was paid, not on the cumulative amount from the date of the agreement.
• The instalment-by-instalment approach typically produces a higher recovery for the allottee than a simplistic "total amount × rate × delay period" calculation.
• Compounding practice varies by state rule; annual compounding is most common.

State authorities have consistently held that interest flows from each payment date, not from a notional project start date or possession-delay start date.

4. Refund: The Allottee's Right to Withdraw

When an allottee elects to withdraw, Section 18 requires:

• Return of all amounts received from the allottee.
• Interest at the prescribed rate on each instalment from the date it was paid until the date of refund.
• Compensation as provided under the Act.

State authorities typically grant a refund window of 45 to 90 days from the date of the order. Delay beyond the ordered window triggers Section 63 daily penalties.

Critically, the refund is from the developer's own funds, not from the project escrow account. The project account under Section 4(2)(l)(D) cannot be tapped for Section 18 refunds.

5. Monthly Interest: The Allottee's Right to Continue

If the allottee does not withdraw, monthly interest accrues until possession is handed over. This creates a continuing liability that:

• Accrues every month the delay continues.
• Is recoverable by the allottee on an ongoing basis or as a lump sum at possession.
• Is often adjusted against the final payment at handover.

Developers frequently attempt to net the monthly interest against any balance payable by the allottee at possession. This is generally permissible if the agreement for sale contemplates such adjustment, but it does not reduce the cumulative liability — it only changes the cash-flow mechanics.

6. The "Possession Date" Trigger

Section 18 kicks in when the promoter fails to deliver possession "in accordance with the terms of the agreement for sale or... by the date specified therein." The possession date as specified in the agreement for sale is the reference point.

Several interpretive issues:

• Grace period. State practice permits a grace period of three to six months if clearly disclosed in the agreement. Beyond grace, Section 18 applies.
• "Subject to" clauses. Possession dates "subject to approvals," "subject to force majeure" or "subject to market conditions" are read narrowly and generally cannot extend the date without specific consent.
• OC-based triggers. Possession is typically tied to receipt of occupancy certificate from the municipal authority. Delay in obtaining OC due to developer-side issues is a Section 18 trigger.

7. Force Majeure Defence: The Narrow Window

Section 6 permits extension of the RERA registration period for force majeure, defined as "any calamity caused by nature affecting the regular development of the real estate project." State authorities have applied Section 6 narrowly:

• Pandemic-related force majeure has been accepted for specific periods tied to government lockdowns.
• Natural calamities (cyclone, flood, fire) with documentary evidence have been accepted.
• General slowdowns in the economy or real estate market have been consistently rejected.
• Contractor defaults have been rejected as valid force majeure.
• Financing disruptions of the developer have been rejected.

A developer invoking force majeure must:

• Document the specific triggering event with government orders or verified records.
• Quantify the days affected with precision.
• Maintain contemporaneous RERA portal updates during the event.
• Seek extension under Section 6 from the Authority rather than asserting the defence unilaterally at the delay stage.

8. Section 72 Compensation

Section 72 provides that in adjudging compensation under Section 18 and other provisions, the Authority shall have due regard to:

• Disproportionate gain to the promoter.
• Loss caused to the allottee.
• Repetitive nature of the default.
• Any other relevant factor.

Section 72 compensation is additional to Section 18 interest. In large consolidated orders, Section 72 compensation has added ten to thirty percent on top of the interest figures.

9. Consolidated Orders

State authorities allow consolidation of multiple allottee complaints arising from the same project. A single adjudication covering 50 or 100 allottees produces a cumulative order that:

• Imposes common findings on project delay.
• Applies uniform interest computation.
• Issues refund directions across the affected allottees.
• Creates substantial settlement pressure on the developer.

Consolidated orders have been the dominant trend in MahaRERA, HRERA Gurugram and KRERA jurisprudence over 2023–2026.

10. Interaction with Consumer Forum Compensation

Section 79 of the RERA Act does not bar consumer forum remedies. Allottees can approach:

• State RERA for refund, interest and compensation under the Act.
• Consumer forums (District, State or National) for compensation for deficiency in service.

The Supreme Court has clarified that the allottee may elect either forum, but generally cannot pursue parallel proceedings for the same cause of action. Consumer forums have, in some cases, awarded compensation exceeding the RERA interest figure — particularly where the consumer forum's assessment of mental agony or deficiency of service adds non-monetary damages.

11. The Appeal Architecture and the Deposit Rule

An appeal from a Section 18 order lies before the state Real Estate Appellate Tribunal within sixty days. Under Section 43(5), the appellant promoter must deposit at least thirty percent of the penalty amount or the entire interest amount due, whichever is higher, before the appeal is entertained.

This deposit requirement makes the appeal economically meaningful only for large orders. For many Section 18 orders, the cost-benefit of appeal is marginal once the deposit and legal fees are added.

12. Settlement and Compromise

State authorities increasingly encourage settlement at the conciliation stage:

• MahaRERA has a Conciliation Forum that has resolved thousands of Section 18 disputes with negotiated interest reductions.
• HRERA and KRERA have similar mediation mechanisms.
• Settlement typically includes: time-bound possession commitment, interest at the prescribed rate for an agreed period, waiver of past delay interest in return for accelerated completion.

Well-structured settlements are often cheaper for developers than fully adjudicated orders, especially where the project is close to completion.

13. Provisioning for Section 18 Liability

At board and CFO level, Section 18 exposure should be provisioned in project financials:

• Base case. Project completes on time; provision nil.
• Moderate delay. Three-month delay; provision at prescribed rate × amounts paid.
• High-risk case. Twelve-month or longer delay; full interest computation.

The provision should be revisited quarterly as construction progress is verified. An under-provisioned project that suddenly runs into Section 18 liability creates balance-sheet shocks that damage the developer's financing relationships.

14. Common Section 18 Defences That Fail

Consolidated state authority jurisprudence has rejected:

• "Possession date was subject to approvals" — general language insufficient.
• "Delay was due to COVID" — without specific documentation and portal updates.
• "Allottee has not paid full amount" — Section 18 interest is on amounts paid, not on balance; the allottee's non-payment is a separate issue.
• "Allottee has already taken fit-out possession" — fit-out possession does not equal legal possession; OC is required.
• "Agreement clause capped developer liability" — contractual caps below the prescribed rate are void.
• "Delay was caused by the contractor's default" — a commercial risk of the promoter, not excusing Section 18.

15. Defences That Sometimes Work

Narrow, documented, contemporaneous defences:

• Specific government-ordered construction ban days, with exact dates and official orders.
• Specific natural calamity events affecting the site.
• Section 14 consent-related delays where two-thirds consent was not promptly obtainable due to allottee-side factors.
• Allottee's own refusal to take possession when offered.
• Mutual extension agreements formally executed with two-thirds allottee consent.

16. Operational Strategies to Reduce Section 18 Exposure

For new projects:

• Realistic timeline with explicit buffer.
• Grace period clearly disclosed.
• RERA registration with conservative completion date.
• Construction-linked payment plan with buffer.

For ongoing projects approaching risk:

• Early communication with allottees.
• Proactive Section 6 extension filing with documented causes.
• Section 14 consent processes for any timeline modification.
• RERA portal quarterly updates with accurate delay disclosure.
• Settlement at the conciliation stage rather than full adjudication.

17. A Working Section 18 Exposure Model

For a 150-unit project with average instalments paid of ₹70 lakh per unit and a twelve-month delay:

• Per-unit exposure: ₹70 lakh × 11% × 12 months = approximately ₹7.7 lakh per unit.
• Project-level exposure: ₹7.7 lakh × 150 = approximately ₹11.5 crore.
• If 30% of allottees elect withdrawal: 45 units × ₹70 lakh = ₹31.5 crore refund principal, plus interest.
• Total exposure on the bad-case: substantially above ₹40 crore in refunds and interest.

Against this, the cost of maintaining strict timeline discipline, quarterly disclosure accuracy and early force majeure filing is a fraction of one percent.

Frequently Asked Questions

Can a developer cap Section 18 interest through a clause in the agreement for sale?▾

No. Section 18 interest is statutorily fixed at the rate prescribed by the state rules, typically SBI's highest MCLR plus two percent. A contractual cap below the prescribed rate is void as contrary to the Act. RERA authorities across states have consistently struck down such caps and awarded full prescribed interest irrespective of the agreement language. The agreement can include provisions on the mechanics of interest payment (for example, credit against final instalment), but cannot reduce the quantum.

Does Section 18 interest run from the date of the original possession date or from the date of the first complaint?▾

Section 18 interest runs from the date of each instalment paid, not from the possession date or complaint date. The statute contemplates that the allottee has parted with money from the date of payment, and is entitled to interest on that money until either refund or possession. State authorities typically compute interest instalment-by-instalment, from each payment date to the date of the order or refund. This is more generous to the allottee than a "delay period only" calculation.

Can a developer use project escrow funds to pay Section 18 refunds?▾

No. The project escrow under Section 4(2)(l)(D) is reserved for construction and land costs, certified proportionately to completion. Section 18 refunds are the developer's own financial obligation and must be paid from the developer's own funds. Using project escrow to satisfy Section 18 obligations is a separate breach of Section 4(2)(l)(D) and exposes the developer to additional Section 61 penalties. Developers should maintain adequate working capital outside the project account for Section 18 contingencies.

If an allottee who chose to continue subsequently elects to withdraw, is that permissible?▾

Yes. The allottee's election under Section 18 is not irrevocable in most state RERA jurisprudence. An allottee who initially chose to continue and then decides to withdraw after further delay can file a fresh Section 18 complaint seeking refund. The monthly interest earned during the continuation period is typically incorporated into the refund calculation. Developers cannot lock an allottee into continuation once the delay exceeds a reasonable further period.

How does Section 18 interact with consumer forum remedies?▾

Section 79 of the RERA Act does not bar consumer forum complaints. Allottees can approach the state RERA or the consumer forum. The Supreme Court has clarified that the allottee can elect either forum, but generally cannot pursue parallel proceedings for the same relief. Some consumer forums have awarded compensation exceeding the RERA interest figure, particularly where the consumer forum assesses additional damages for mental agony or deficiency in service. Developers should track both forums in their litigation dashboard.

Can the developer and allottee agree to a lower interest rate in settlement?▾

Yes. A settlement agreement can specify a lower interest rate or a lump-sum settlement amount that differs from the prescribed rate, provided the settlement is voluntary and properly documented. The RERA authority will generally honour a settlement reached at the conciliation stage. The settlement must be in writing, signed by the allottee (or a duly authorised representative), and filed with the authority. Attempting to impose a lower rate through standard agreement language, without a specific settlement process, is ineffective.

Does Section 18 apply to commercial projects or only to residential?▾

Section 18 applies to all real estate projects as defined in Section 2(zn), which includes commercial, residential and mixed-use projects. Commercial allottees have the same rights as residential allottees — refund with interest or monthly interest during delay. In fact, commercial allottees in office and retail projects have pursued Section 18 remedies successfully in MahaRERA and HRERA, with tenant lease timelines often driving the urgency.
