Duality in the context of UK income tax and corporation tax refers to the principle that an expenditure is not deductible in computing profits subject to tax if it serves both personal and business purposes. The duality principle ensures that only those expenditures which are incurred wholly and exclusively for business purposes are eligible for tax deduction.
Historical Context
The concept of duality in tax law has its roots in the historical development of taxation principles in the United Kingdom. The principle was established to maintain fairness and prevent the misuse of tax deductions. Over the years, various tax cases have refined and clarified the application of this principle.
Types/Categories
Dual Purpose Expenditures
- Mixed Personal and Business Use: Expenses that have both personal and business elements.
- Dissectible Business Expenses: Expenses where a portion can be identified as purely business-related.
Key Events
- 1982: The case of Bentleys, Stokes and Lowless v. Beeson established the non-deductibility of dual-purpose expenses.
- 2000: Introduction of the Finance Act further clarified rules around business expenditures.
Detailed Explanation
Duality denies tax relief by apportionment but allows dissection where a wholly business expenditure is identifiable.
Mathematical Models/Formulas
There isn’t a specific formula for duality but understanding the principle helps:
