What Is a Sinking Fund in a Housing Society? Rules, Rates & Compliance in India

Under Bye-Law 47, every member must contribute a minimum of 0.25% per annum of the construction cost of the building, allocated proportionally to each flat's area. The construction cost is determined by a registered valuer and should be updated periodically (typically every 5 years or when a structural audit is conducted).

Example: If the construction cost of a 1,000 sq ft flat is ₹50,00,000, the annual Sinking Fund contribution is ₹12,500 (₹50,00,000 × 0.25%). Monthly contribution = ₹1,042. The managing committee can fix a higher rate at the AGM based on the building's age and projected repair requirements, the 0.25% is a floor, not a ceiling.

Societies with old buildings (30+ years) should consider higher contribution rates. A structural audit by a licensed structural engineer typically recommends a 10–15 year repair schedule, the Sinking Fund should be sized to meet those projected costs.

The Sinking Fund can only be used for: (1) major structural repairs (foundation, columns, beams, slabs, external plastering), (2) reconstruction or redevelopment of the building, and (3) repayment of loans taken for the above purposes. Day-to-day maintenance, painting, plumbing repairs and other non-structural work must be funded from the Repair Fund or maintenance charges.

Using the Sinking Fund for non-structural purposes is a bye-law violation. If the auditor finds that Sinking Fund money was used for ineligible expenses, the managing committee can be held personally liable for reimbursing the fund. This is a serious risk that many committees underestimate.

Any withdrawal from the Sinking Fund requires a special resolution passed by at least two-thirds of the members at a general body meeting. The resolution must specify the purpose, the estimated cost and the approval of a structural engineer's report.

The Repair Fund (also called the Major Repairs Fund) is distinct from the Sinking Fund. The Repair Fund covers non-structural repairs, lift maintenance, plumbing, electrical work, internal painting and common area maintenance. The contribution rate is decided by the managing committee at each AGM based on projected needs.

The Sinking Fund is for structural and reconstruction work only. Both must be maintained in separate bank accounts and must be accounted for separately in the books. A common error is treating both as a single 'repair and maintenance' fund, the auditor will flag this.

From an accounting perspective, contributions to both funds are credited to a Liability account (Sinking Fund Liability / Repair Fund Liability) in the Balance Sheet. When funds are drawn for an approved purpose, they are debited against this liability account and credited to the Society's bank account.

The Sinking Fund must appear separately in the Balance Sheet as a liability (since it belongs to members, not the society). The annual income from interest earned on the Sinking Fund bank account must be credited back to the Sinking Fund, it cannot be used for general expenses.

The statutory auditor verifies: the opening balance of the Sinking Fund, contributions received during the year, interest credited, any withdrawals and their authorization (special resolution copy), and the closing balance reconciled to the bank statement. Discrepancies are reported in Form J.

Societies that use SocietyBee can track Sinking Fund contributions automatically, each member's monthly contribution is billed as a line item, recorded as a credit to the Sinking Fund Liability account, and the fund balance is visible in the Balance Sheet at all times.
