Work and employment / deduction

Other employment expenses: the wholly, exclusively and necessarily test

Employees can deduct an expense only if it was incurred wholly, exclusively and necessarily in performing the duties of the job and was not reimbursed. This is a strict test: travel to work, ordinary clothing and most home costs fail it. Professional subscriptions required by the job and specialist equipment can pass.
