Society surplus funds are often placed in bank fixed deposits, which earn interest. If the deposit is with a co-operative bank, the interest is not taxable. However, the bank may still deduct TDS. To recover this, simply file your income tax return at the end of the financial year and claim the refund. Do note: this tax exemption applies only to FDs held in co-operative banks.
You will need to appoint a Chartered Accountant to file the income tax return and pay the applicable fees.
