Start with the stage you are in. The table below is the usual position under standard builder-buyer agreements and RERA; your own agreement clause and state rules decide the fine print.
| Stage | Monthly maintenance | Corpus / IFMS | Property tax and outgoings |
|---|---|---|---|
| Before the OC is issued | Generally not chargeable. The building is not legally occupiable, so there is no lawful possession to maintain against | Not yet due in most agreements | Builder's burden under RERA Section 11(4)(g) |
| After OC, before a valid possession offer to you | Disputed zone. Many agreements start maintenance from the “offer of possession”; an offer is valid only if backed by the OC and the unit is actually ready | Usually demanded with the possession offer, per the agreement | Still the builder's until transfer |
| After a valid offer, before you take keys | Commonly chargeable from the offer date or a short grace period after it, if the agreement says so. Check the clause, not the builder's letter | Payable per the agreement, against receipt, into an identifiable fund | Shifts per the agreement; municipal tax follows occupation and assessment |
| After you take possession | Chargeable as agreed, with an itemised rate and period | Already paid; demand the fund statement later at handover | Yours for your flat; common-area outgoings stay with whoever runs maintenance |
Three different demands hide inside one builder invoice, and they have different rules:
A Chennai buyer received a possession-offer letter demanding Rs 2.92 lakh: 24 months advance maintenance at Rs 4.50 per sq ft on a 1,400 sq ft flat (Rs 1.51 lakh), a corpus of Rs 75 per sq ft (Rs 1.05 lakh), and Rs 36,000 as “pro-rata property tax”. The letter was dated March; the CMDA records showed no completion certificate yet. Taken apart: the maintenance demand fails because there was no lawful offer without the certificate; the corpus may be contractually due at possession, but only at actual, valid possession; and the pre-possession “property tax” line was the builder's own Section 11(4)(g) liability dressed up as a buyer charge. The buyer's written reply asking for the certificate, the agreement clause for each line, and an itemised period cut the demand to the corpus alone, payable at genuine handover.
Tamil Nadu buyers should ask for the completion certificate position from CMDA or the local body; in states issuing occupancy certificates, ask for the OC. Either way, verify with the authority, not the builder's covering letter.
Maintenance charges attract 18 percent GST where the monthly charge per flat exceeds Rs 7,500 (and the supplier crosses the turnover threshold). Two checks: the invoice must show the builder's or agency's GSTIN if GST is billed, and GST cannot be charged on a corpus deposit that is a returnable reserve rather than a service. Ask for a tax invoice, not a “demand letter”, before paying anything with GST added.
The builder is outside RTI, but the facts that decide this dispute are public records:
File through RTI online or your state RTI portal. Frame questions around records, not grievances, or the PIO will reject them, see why RTI gets rejected.
Only if your agreement genuinely provides it and the offer was valid, meaning the certificate existed and the flat was ready. A deemed date in a letter cannot override the absence of an OC.
Advance collection is common and usually contractual, not illegal in itself. The questions are whether the trigger date is lawful and whether the unspent advance will be accounted to the association later, see maintenance transfer to the society.
Record that condition in writing, pay disputed amounts under protest if you need the keys, and raise the coercion squarely in your RERA complaint. Conditioning lawful handover on a contested charge is a standard RERA grievance.
Usually not, if your agreement provides for it at possession. What you can demand is a receipt, the fund's destination, and later its transfer with interest to the association.
That clause typically binds you only where the offer is valid, certificate in place and unit complete. If either is missing, contest the start date in writing with the clause quoted.
No. Whatever you pay now, control must pass once the association takes over, and the builder must account for collections at that point.
