Deductions from general earnings: introduction
Section 327 to 332 ITEPA 2003
This chapter introduces the principal rules that allow deductions from employment income. The table in EIM31611 explains where you can find particular instructions.
Income Tax is chargeable on employment income. Employment income consists of general earnings and specific employment income, see EIM00510. This chapter deals with deductions from general earnings.
There are a number of general principles to be applied. The only deductions that can be made are those that are expressly permitted by statute. Most deductions can be made from any general earnings but some are limited to the earnings to which they relate.
Except where otherwise specified the amount of a deduction cannot exceed the earnings from which it is deducted and a deduction can only be made once for a single expense.
