Flat Maintenance Charges and GST: What a Buyer Should Know

A Bengaluru buyer worked out his EMI to the rupee, then moved into his new flat and found a maintenance bill he had never factored in: a monthly charge for the common areas, plus 18 percent GST on top because the charge crossed a threshold he had never heard of. Maintenance is the cost that does not appear in the brochure or the loan sheet, yet it arrives every month for as long as you own the flat. Knowing how it is set, and when tax is added, keeps it from becoming an unpleasant monthly surprise.

The short answer. Monthly maintenance pays for the upkeep of shared areas and amenities, and it is exempt from GST as long as it does not exceed 7,500 rupees per flat per month. Cross that figure and GST at 18 percent applies to the whole amount, not just the part above 7,500, and only where the association's annual turnover also exceeds 20 lakh rupees. The trade-off to understand: a flat with lavish amenities carries higher maintenance, and once the monthly charge crosses 7,500 rupees the tax turns a 8,000 rupee bill into about 9,440 rupees, so the amenities you admire at the sales office have a recurring cost attached.

What do maintenance charges actually cover?

They cover the running of everything you share with your neighbours, from the lifts and lobbies to security, water pumps, common lighting, landscaping and amenities like a gym or pool. The charge is usually worked out per square foot of your flat or as a flat rate per unit, and it is collected by the residents' association once it is formed, or by the builder before handover. A larger flat or an amenity-heavy project naturally carries a higher monthly charge, which is why two buyers in different projects can pay very different maintenance for similar-sized homes. It is a genuine recurring cost of ownership, not a one-time fee, so it belongs in your monthly budget alongside the EMI rather than being treated as an afterthought.

Separately, builders often collect a one-time interest-free maintenance deposit and a corpus or sinking fund at handover, which are different from the monthly charge and are meant for long-term and major repairs. These one-time collections can be substantial, sometimes running to a year or two of maintenance in a single payment, so a buyer focused only on the monthly figure can be caught out by the lump sum due at possession. The interest-free deposit is typically held against future maintenance and parked by the builder or association, while the corpus or sinking fund is reserved for big-ticket work such as repainting the building, replacing lifts or major plumbing, which a monthly charge alone would never cover. Knowing which of these you are being asked for, and how much, is part of understanding the true cost of moving in.

When is GST added to maintenance?

GST applies only when two conditions are both met: the monthly charge exceeds 7,500 rupees per flat, and the association's annual turnover exceeds 20 lakh rupees. As Outlook Money's explainer on GST on maintenance notes, citing CBIC Circular 109/28/2019, monthly maintenance up to 7,500 rupees per member is exempt, and GST applies only when both the 7,500 rupee and the 20 lakh rupee thresholds are crossed. If the per-flat charge stays at or below 7,500 rupees, there is no GST even if the society's total collection is large. Equally, a small society whose turnover is under 20 lakh rupees does not charge GST even if a flat's maintenance is higher. Both gates have to open before the tax applies. This two-part test is where billing errors creep in. Some builder-managed or newly formed societies apply GST too readily, charging it on a flat whose maintenance is below 7,500 rupees, or where the body's turnover has not actually crossed 20 lakh rupees. Because an owner pays this month after month, a wrongly applied 18 percent is not a one-off; it compounds over the years you hold the flat. A resident who understands both conditions can question a bill that does not fit them and ask for it to be corrected, which is far easier to do early than to unwind after years of paying.

Why does crossing 7,500 rupees cost more than it looks?

Because once the monthly charge exceeds 7,500 rupees, GST at 18 percent applies to the entire amount, not just the portion above 7,500. So a charge of 8,000 rupees does not attract tax on the 500 rupee excess; it attracts 18 percent on the full 8,000 rupees, adding about 1,440 rupees and taking the bill to roughly 9,440 rupees. A flat sitting just above the threshold therefore pays noticeably more than one sitting just below it. Statutory charges such as property tax, water and electricity are kept out of the 7,500 rupee calculation, so it is the maintenance component that matters for the threshold. The cliff at 7,500 rupees is the single most important number for a buyer to know, because it turns a small difference in the charge into a larger difference in the bill. It is also why the per-square-foot maintenance rate deserves a look at the shortlisting stage. A rate that sounds modest can push a larger flat over the threshold, while the same rate leaves a smaller flat comfortably below it, so the tax outcome depends on both the rate and your flat's size. Buyers comparing two projects on price alone can miss that the amenity-heavy one carries a maintenance charge over the line, quietly adding the 18 percent for the life of their ownership.

How do the thresholds and charges fit together?

The table below lays out the rules so you can see when the tax applies and what it does to the bill.

What should a buyer check before moving in?

You find out the monthly charge, how it is set, and what deposits are due at handover, so nothing is a surprise. The checklist below covers the questions worth asking the builder or association.

1. Ask for the monthly maintenance charge per flat in writing, and how it is calculated.
2. Check whether it is at or above 7,500 rupees, which decides if GST can apply.
3. Confirm whether the association's turnover exceeds 20 lakh rupees, the second GST gate.
4. Ask for the one-time maintenance deposit and the corpus or sinking fund amount due at handover.
5. Confirm whether statutory charges like water and electricity are billed separately or bundled.
6. Find out when the association is formed and maintenance handed over from the builder.
7. Build the monthly maintenance, plus any GST, into your budget alongside the EMI.

What should a buyer watch out for?

The commonest surprise is simply not budgeting for maintenance at all, then meeting it as a new monthly outflow after possession. The next is being charged GST incorrectly, either when the charge is at or below 7,500 rupees, or when the society's turnover is under the threshold, in which case residents can ask for corrected billing. A third is the one-time deposits at handover, which can run to a large sum and are easy to overlook when the whole focus is on the EMI. Because maintenance begins around the time you take possession, it sits close to the handover documents; our guide to the occupancy certificate and completion certificate covers what must be in place first, and the terms on maintenance and association handover should be in the agreement you read, as set out in our guide to the builder-buyer agreement clauses. When you compare projects, say an amenity-rich tower against a quieter one like DSR The Courtyard in Gunjur, the monthly maintenance belongs in the comparison, not just the price.

Frequently asked questions

Is GST charged on apartment maintenance?

Only when two conditions are both met: the monthly maintenance exceeds 7,500 rupees per flat, and the association's annual turnover exceeds 20 lakh rupees. If the charge is at or below 7,500 rupees, there is no GST, and a small society under the turnover limit does not charge it either. The exemption follows CBIC Circular 109/28/2019.

How much GST applies if maintenance crosses 7,500 rupees?

GST at 18 percent applies to the entire maintenance amount, not just the part above 7,500 rupees. So an 8,000 rupee monthly charge attracts tax on the full 8,000, adding about 1,440 rupees and taking the bill to roughly 9,440 rupees. A flat just above the threshold therefore pays noticeably more than one just below it.

Does the 7,500 rupee limit apply per flat or per person?

The exemption limit applies per flat per month, so an owner of two flats in the same society gets the 7,500 rupee limit separately for each. Statutory charges such as property tax, water and electricity are kept outside the calculation, so it is the maintenance component that is measured against the 7,500 rupee threshold.

What is a sinking fund or corpus, and is it the same as maintenance?

No. A sinking fund or corpus is usually a one-time contribution collected at handover and set aside for major future repairs, separate from the monthly maintenance for day-to-day upkeep. Builders also often collect a one-time interest-free maintenance deposit. Confirm all of these amounts before possession, as their GST treatment can differ and is best checked with a professional.

The short version: maintenance is a lifelong monthly cost, exempt up to 7,500 rupees per flat and taxed at 18 percent on the whole amount above that. Ask for the charge and the deposits in writing, and budget them alongside the EMI, because unlike the one-time costs of buying, this is a bill you will pay every month for as long as you own the home.
