Apartment Maintenance, the 7,500 Rupee GST Line, and KAOA: A Bengaluru Buyer Guide

The sales brochure prices the flat. Nobody prices the next thirty years of living in it. A Bengaluru family buying a 1,400 square foot apartment in a full-amenity gated community can face maintenance charges that rival a small EMI, and many discover only at their first society billing cycle that an 18 percent GST line has appeared on top. In early 2025, tax notices to resident welfare associations across Karnataka pushed this long-ignored rule into apartment WhatsApp groups, and the confusion has not settled since. Here is what the law actually says, what your monthly outgo really funds, and what every buyer should calculate before booking.

The short answer. GST at 18 percent applies to apartment maintenance only when two conditions are met together: the monthly contribution per member exceeds 7,500 rupees, and the association's annual collections exceed 20 lakh rupees, the threshold requiring GST registration. If both are crossed, the prevailing central interpretation taxes the entire amount, not just the excess, though the Madras High Court has read it as taxing only the portion above 7,500 rupees, a ruling that applies in Tamil Nadu and has not been tested at the Supreme Court. The trade-off for buyers: bigger amenity decks mean bigger maintenance, and crossing the 7,500 rupee line in a registered society adds 18 percent to the entire bill in most of Karnataka's current practice. Amenities are not free at purchase, and they are never free afterward.

When exactly does GST apply to maintenance charges?

The structure is a two-key lock, and both keys must turn. First key: the association's aggregate annual turnover. If total collections stay under 20 lakh rupees a year, the association need not register for GST at all, and no GST applies regardless of what any individual flat pays per month. Second key: the per-member monthly contribution. Even a registered association charges GST only on members whose monthly contribution exceeds 7,500 rupees. Smaller societies with high charges, and large societies with modest charges, can each escape the net; it is the combination of scale and high per-flat billing that triggers tax. Explainers such as ClearTax's guide to GST on housing maintenance lay out the mechanics, and the Business Today coverage of the 2025 clarifications is a useful companion for how enforcement has tightened without the underlying rule changing since 2019.

Is GST charged on the whole amount or only the excess?

This is the live controversy, and honesty requires presenting both positions. The central board's 2019 circular says that once the 7,500 rupee threshold is crossed, GST applies to the entire contribution, so a flat paying 9,000 rupees a month is taxed on the full 9,000, an outgo of 1,620 rupees, not on the 1,500 rupee excess. The Madras High Court disagreed, calling the all-or-nothing reading arbitrary and holding that only the amount above 7,500 rupees should be taxed. That ruling binds in Tamil Nadu and has not been overturned, but it has also not been adopted nationally, which leaves Karnataka associations facing officers who typically apply the harsher circular. A Bengaluru buyer should budget on the conservative reading: full-amount taxation once both thresholds trip. If jurisprudence later softens the rule, the surprise will be pleasant, which is the right direction for surprises in household budgeting.

What does maintenance actually pay for, and what is fair?

A typical Bengaluru gated community's maintenance covers security, housekeeping, common-area power and the diesel that bridges outages, water procurement including tankers where Cauvery supply is absent, lift contracts, sewage treatment plant operation, landscaping, amenity upkeep, staff salaries, insurance, and a sinking fund for the building's long-term repairs. Charges are usually levied per square foot per month, which is why larger flats pay more for identical services. What is fair varies with what exists: a project running a large clubhouse, multiple pools, and acres of landscaping costs structurally more than a no-frills society, and the gap is permanent. The buyer's mistake is comparing two projects' prices without comparing their maintenance structures, because over a long ownership the difference compounds into lakhs. Ask for the current per-square-foot rate, the last two years of society accounts where the project is occupied, and the sinking fund balance; those three numbers describe the building's financial health better than the lobby does.

Where does the Karnataka Apartment Ownership Act fit in?

The Karnataka Apartment Ownership Act, 1972 is the legal frame under which apartment owners hold their individual units along with an undivided interest in common areas, and under which owners' associations are constituted with the power to levy and collect these charges. A society properly organised under the applicable framework, with a registered deed of declaration, gives the association clear authority over common areas and gives owners enforceable rights in them. Buyers rarely check this layer, but it surfaces at the worst times: societies with defective or missing declarations face disputes over who controls common areas, whether the builder retained rights it should have surrendered, and whether charges are validly levied. When you buy, especially resale, ask whether the association is duly registered, whether the declaration covers the common areas as built, and whether the developer has formally handed over the corpus and the common areas. A clean handover history is worth a premium that never appears in any listing. The reverse is also true: societies where the builder still controls maintenance years after completion, collects charges through its own facility arm, and has never convened a proper association are carrying a governance defect that eventually erupts into disputes over accounts, vendor contracts, and the unspent corpus. Asking who actually runs the building, owners or builder, is a one-question audit of its civic health.

How should maintenance shape your purchase decision?

Arithmetically, before emotionally. Convert the quoted per-square-foot rate into the monthly and annual cash cost for the specific flat, add GST if the project's positioning makes threshold-crossing likely, and place that figure alongside your EMI as a permanent obligation that rises with inflation and never amortises. A 4 rupee per square foot charge on a 1,800 square foot flat is 7,200 rupees a month before tax, on the edge of the GST line; the same flat in a heavier-amenity project at 6 rupees crosses it decisively and costs over 12,700 rupees a month with tax under prevailing practice. Neither number is wrong, but each belongs in the affordability calculation at purchase, not as a surprise at the first billing. The corollary: amenities you will not use are a tax you volunteer for. A family that swims weekly is buying something real; a family that never will is subsidising the neighbours' lifestyle in perpetuity.

Your seven point maintenance diligence checklist

1. Get the current maintenance rate per square foot in writing and compute your flat's monthly cost.
2. Ask whether the society's annual collections exceed 20 lakh rupees and whether it is GST-registered.
3. Budget 18 percent GST on the full amount if your monthly charge will exceed 7,500 rupees.
4. For occupied projects, review the last two years of association accounts and the sinking fund balance.
5. Confirm the owners' association is duly registered and the deed of declaration covers common areas.
6. Verify the developer has handed over the corpus fund and common areas, with documentation.
7. Compare amenity loads across your shortlist against what your household will genuinely use.

What is the bottom line for Bengaluru buyers?

Maintenance is the purchase price you keep paying, and the GST rules have made its structure consequential in a way brochures never disclose. The two-threshold test is mechanical once you know it: society turnover above 20 lakh rupees, member contribution above 7,500 rupees, and in Karnataka's prevailing practice the whole bill then carries 18 percent. None of this should frighten a buyer away from full-amenity living; it should simply enter the spreadsheet at the same moment as the EMI, the property tax, and the parking charge. The projects that deserve your money are the ones whose associations can show you clean accounts, a funded sinking fund, and a lawful structure under the state's apartment ownership framework. Everything else is landscaping.

When is GST charged on apartment maintenance?

Only when two conditions are met together: the resident welfare association's annual collections exceed 20 lakh rupees, requiring GST registration, and the individual member's monthly contribution exceeds 7,500 rupees. If either condition fails, no GST applies. When both are met, the prevailing central interpretation levies 18 percent on the entire contribution, not merely the portion above the threshold.

Is GST payable on the full maintenance amount or only above 7,500 rupees?

Under the 2019 central circular followed in most states including Karnataka, crossing the threshold makes the entire amount taxable at 18 percent. The Madras High Court has held that only the excess above 7,500 rupees should be taxed, but that ruling applies in Tamil Nadu and has not been adopted nationally. Bengaluru buyers should budget on the full-amount basis.

What does the Karnataka Apartment Ownership Act do for flat owners?

The 1972 Act provides the framework under which you own your flat along with an undivided share in common areas, and under which the owners' association is constituted with authority to levy maintenance and manage the property. A registered deed of declaration and a documented handover of common areas and corpus from the builder are the practical proof that this framework is properly in place.

How do I evaluate maintenance costs before buying a flat?

Convert the per-square-foot rate into your flat's actual monthly and annual cost, add 18 percent GST if charges will exceed 7,500 rupees in a registered society, and treat the total as a permanent, inflating obligation alongside your EMI. For occupied projects, read the association's accounts and sinking fund balance, and weigh the amenity load against what your household will truly use.
