You may be able to claim tax relief if you have to use your own money for travel or things that you must buy for your job.
You can only claim relief on things that are used just for your work, and which you don’t use in your private life.
You can’t claim relief on things you’ve spent money on if your employer has already provided you with an alternative.
You must keep records of what you’ve spent, and claim within 4 years of the end of the tax year that you spent the money.
If your employer has paid back your expenses, you can’t claim tax relief.
