What does disallowance u/s 40 a(3) mean?

Section 40 a(3) of the Income Tax Act pertains to cash payments exceeding £10,000 in a single day. This disallowance means that such expenses will be added back to your business income, potentially increasing your tax liability. It's crucial for businesses, particularly limited companies filing under 'Profits and Gains from Business and Profession', to adhere to these rules and avoid making disallowed cash transactions.
