As per Sec 192 Any person responsible for paying any income chargeable under the head ‘Salaries’ shall, at the time of payment, deduct income-tax on the amount payable at the average rate of income-tax computed on the basis of the rates in force for the financial year in which the payment is made, on the estimated income of the assessee under this head for that financial year.
Most Important to note that in Other Sections of TDS it is mentioned that Where any sum referred to in sub-section (1) is credited to any account, whether called “Suspense account” or by any other name, in the books of account of the person liable to pay such income, such crediting shall be deemed to be credit of such income to the account of the payee and the provisions of this section shall apply accordingly.
It Clearly means that apart from salary if any expenses are recorded as a provision then also TDS is required to be deducted from that amount.
If we look into Sec 40(a)(ia) which talks about the “Amounts Not Deductible” from the Total Income it states that thirty per cent of any sum payable to a resident, on which tax is deductible at source under Chapter XVII-B and such tax has not been deducted or, after deduction, has not been paid on or before the due date specified in sub-section (1) of section 139:
Explanation.—For the purposes of this sub-clause,—
(i) “commission or brokerage” shall have the same meaning as in clause (i) of the Explanation to section 194H;
(ii) “fees for technical services” shall have the same meaning as in Explanation2 to clause (vii) of sub-section (1) of section 9;
(iii) “professional services” shall have the same meaning as in clause (a) of the Explanation to section 194J;
(iv) “work” shall have the same meaning as in Explanation III to section 194C;
(v) “rent” shall have the same meaning as in clause (i) to the Explanation to section 194-I;
(vi) “royalty” shall have the same meaning as in Explanation 2 to clause (vi) of sub-section (1) of section 9;
Nowhere in Sec 40 also Salary is mentioned.
Only in 40(a)(iii) it is mentioned that any payment which is chargeable under the head “Salaries”, if it is payable—
(A) outside India; or
(B) to a non-resident,
and if the tax has not been paid thereon nor deducted therefrom under Chapter XVII-B;
Hence in case if we record Provision for Salary or Bonus or incentive on Year end provision then TDS is not required to be deduct on it. TDS is required to be deduct in the month when payment is made.
