SALARY PAYMENT TO SPOUSE

Yes
Salary can be paid to a spouse of a member.
However, section 40A(2) of the Income Tax act should be kept in mind where "excessive" or "unreasonable" payment is disallowed as an expenditure.
 

Yes Salary can be paid to Spouse of a Partner in a Partnership Firm. As rightly said by Mr. Shubham Sir, you have to keep in mind the Provision of Section 40A(2) of the Income Tax Act 1961.

Can anyone explain the same with an example?

Yes

You can paid salary to Partner Spouse if actually works in Partnership Firms

No restrictions

@ Anirban Dey- Suppose partnership firm pays a high amount of salary, say 20,00,000 per year to the spouse. Now suppose rhe Assessing Officer is of opinion that someone with educational qualification and prior work experience of spouse is expected to be paid around 8,00,000. So he/she may disallow excess 12,00,000 under section 40A(2).

Very good reply by Mr. Shubhan
