it to the credit of Central Government’s account:-
a) Disallowance of expenditure

As per section 40(a)(i) of the Income-tax Act, any sum (other than salary) payable outside India or to a non-resident, which is chargeable to tax in India in the hands of the recipient, shall not be allowed to be deducted if it is paid without deduction of tax at source or if tax is deducted but is not deposited with the Central Government till the due date of filing of return.
​
However, if tax is deducted or deposited in subsequent year, as the case may be, the expenditure shall be allowed as deduction in that year.
Similarly, as per section 40(a)(ia), any sum payable to a resident, which is subject to deduction of tax at source, would attract 30% disallowance if it is paid without deduction of tax at source or if tax is deducted but is not deposited with the Central Government till the due date of filing of return.
However, where in respect of any such sum, tax is deducted or deposited in subsequent year, as the case may be, the expenditure so disallowed shall be allowed as deduction in that year.
As per Section 58(1A) (as amended with effect from the assessment year 2018-19), the provisions of section 40(a)(ia) and 40(a)(iia) shall also apply in computing the income chargeable under the head “Income from other sources”.


b) Levy of interest

As per section 201 of the Income-tax Act, if a deductor fails to deduct tax at source or after the deducting the same fails to deposit it to the Government’s account then he shall be deemed to be an assessee-in-default and liable to pay simple interest as follows:-
(i) at one per cent for every month or part of a month on the amount of such tax from the date on which such tax was deductible to the date on which such tax is deducted; and
(ii) at one and one-half per cent for every month or part of a month on the amount of such tax from the date on which such tax was deducted to the date on which such tax is actually paid.​
