Maintenance Charges, GST and the Sinking Fund: A Bengaluru Apartment Buyer Guide

A buyer taking over a resale flat in a large Bengaluru complex in mid 2026 budgeted carefully for the EMI and the registration, then was surprised twice after moving in. The monthly maintenance was higher than expected because the association crossed the GST threshold, and within a year a special levy landed for lift replacement because the sinking fund had run thin. Neither was hidden. Both were knowable before the purchase, in a few minutes of asking, and neither had been raised at any point during the deal.

The short answer. Your monthly cost of living in an apartment is more than the EMI. It includes routine maintenance, a sinking fund for big future repairs, and sometimes GST. GST applies to maintenance only when both the monthly charge per member is above seven thousand five hundred rupees and the association annual turnover is above twenty lakh rupees, and when both are crossed the CBIC position is that the tax applies on the full amount, as explained at cbic-gst.gov.in. The trade off for a buyer is simple, ask about these numbers before you buy, not after, because they shape your real monthly outgo and can hide a large levy down the line.

What do maintenance charges actually cover?

Maintenance charges pay for running the building you share with your neighbours. They cover the upkeep of common areas, security, lighting and water for shared spaces, lift servicing, housekeeping, and the salaries of the staff who keep the complex functioning. In most apartments the charge is worked out per square foot per month or as a flat amount per unit, and it is collected by the owners association or the managing committee.

Because it is a recurring cost for the life of your ownership, maintenance deserves as much attention as the one time costs of buying. A large complex with a swimming pool, a gym and landscaped grounds costs more to run than a simple building, and that shows up in your monthly charge. Neither is wrong, but you should know what you are signing up for, since a high monthly outgo can matter as much to your budget as the EMI itself.

It also helps to see the maintenance charge as separate from your property tax and your own metered utilities. The property tax goes to the city, your electricity and water usage are billed to you, and the maintenance charge covers the shared running of the building. Keeping the three distinct stops you double counting or missing one entirely when you plan your monthly budget.

When does GST apply to maintenance?

GST on maintenance is not automatic, it depends on two thresholds being crossed together. The tax applies only when the monthly maintenance per member is more than seven thousand five hundred rupees and the association annual turnover is above twenty lakh rupees. If your monthly charge is below that figure, or the association is small enough that its turnover stays under the limit, no GST is charged at all. Many buyers assume GST always applies, or never applies, when the truth sits in between.

When both thresholds are crossed, the CBIC position is that GST applies on the full monthly contribution, not merely the part above seven thousand five hundred rupees. This is an important detail, because it means crossing the threshold by a small margin can add tax to the entire amount. A Madras High Court ruling has taken a different view, arguing only the excess should be taxed, so the treatment can be contested, and the practical answer is to ask your specific association how it applies the rule rather than assuming.

For a buyer the useful takeaway is not to memorise the tax mechanics but to ask the right question, is GST being charged on this flat maintenance, and if so, on what basis. In a large premium complex with rich amenities the monthly charge can sit comfortably above the threshold, so GST is a real part of the outgo. In a smaller or simpler building it may not apply at all. Either way, you want the answer in a figure you can budget, not a vague reassurance that it is all included.

What is a sinking fund and why does it matter?

A sinking fund is the money an association sets aside for big, occasional expenses, and it is one of the most overlooked things a buyer should check. Buildings need major work over their lifetime, repainting, waterproofing, replacing a lift, or structural repairs, and these cost far more than routine maintenance can absorb in a single month. The sinking fund spreads that cost by collecting a small amount regularly, so the money is there when the work is needed.

For a buyer, the health of the sinking fund is a quiet but important signal. A well funded reserve means a major repair can be met without a sudden demand on owners, while a depleted or non existent fund means the next big job may arrive as a special levy that can run into a large one time payment per flat. Contributions to a sinking fund are generally treated as a corpus set aside for the future, kept separate from routine upkeep, and a buyer should ask for the current balance as part of due diligence.

Think of it the way a prudent household keeps an emergency fund. A building that collects steadily and invests the reserve sensibly is one where a lift failure or a monsoon damaged terrace is an inconvenience rather than a crisis. A building that has spent its reserve, or never built one, pushes those costs onto whoever owns the flat when the bill arrives, which could be you within months of moving in. Asking for the sinking fund balance, and how the association plans for major works, tells you a great deal about how well the complex is actually run.

How do the pieces of my monthly cost fit together?

It helps to see the whole picture rather than a single number. The table below separates the main recurring costs so you can budget each one honestly.

What can go wrong, and how do I protect myself?

The two classic surprises are the ones from our opening example, unexpected GST and an unfunded major repair. Both are avoidable with a few questions before you buy. Ask for the current monthly maintenance and how it is calculated, whether GST is being charged and on what basis, the balance in the sinking fund, and whether the seller has cleared all dues, because unpaid maintenance can attach to the flat and become your problem. Use the checklist below.

1. Get the current monthly maintenance figure and the basis, per square foot or per flat.
2. Ask whether GST is charged, and confirm whether both thresholds are actually crossed.
3. Request the sinking fund balance and any planned major works in the near future.
4. Obtain a no dues certificate confirming the seller has cleared all maintenance.
5. Check for any special levy already announced or likely, such as for a lift or painting.
6. Read the association rules on how charges are set and revised each year.
7. Add the full monthly outgo, not just the EMI, into your household budget before you commit.

How does this fit my wider buying checks?

Maintenance and the sinking fund are part of the handover picture, and they read best with the related checks. To understand how the initial corpus and the association itself are handed over from the builder, see our guide to the apartment association handover and corpus fund, and to place the GST on your monthly charge alongside the GST on the purchase itself, read our explainer on GST on an under construction versus a ready flat. Together they turn the recurring cost of ownership from a surprise into a line you planned for. The habit worth building is to treat the monthly maintenance, the sinking fund and any GST as part of the true price of the home, not an afterthought, so the flat you can comfortably afford is the one whose total monthly cost, and not just its EMI, fits your budget for the long run.

When does GST apply to apartment maintenance charges?

GST applies only when two conditions are both met, the monthly maintenance per member is more than seven thousand five hundred rupees, and the association annual turnover is above twenty lakh rupees. If either condition is not met, no GST is charged. When both are crossed, the tax applies at the standard rate, which the CBIC explains at cbic-gst.gov.in.

Is GST charged on the full amount or only the excess over 7500?

The CBIC position is that once both thresholds are crossed, GST applies on the full monthly contribution, not just the part above seven thousand five hundred rupees. A Madras High Court ruling took a different view, that only the excess should be taxed, so the exact treatment can be contested. Confirm how your own association applies it.

What is a sinking fund in an apartment?

A sinking fund is a reserve the association builds up over time to pay for major future work, such as repainting the building, replacing a lift, or structural repairs. It is collected in small regular amounts so that a large expense later does not fall on owners all at once. It is a corpus for the future, kept separate from routine monthly upkeep.

What should a buyer check about maintenance before buying?

Ask for the current monthly maintenance figure and how it is calculated, whether GST applies, the sinking fund balance, and whether the seller has any unpaid dues. Unpaid maintenance can follow the flat, and a thin sinking fund can mean a large special levy later, so both belong in your checks before you agree a price.
