point
What can be deducted?
You cannot deduct expenditure in computing the profits of a
business for income tax purposes if, either:
- it falls within the scope of any of the prohibitions specified
in The Taxes Acts (for example entertaining, ICTA88/S577), or
- it is not a proper debit item to be charged under ordinary
commercial principles against the incomings of the business in
computing the balance of the profits.
