What is a form P45?
• A form P45 is completed by your employer when you leave a job. He will detach Part 1 and send it straight away to your tax office. He will then hand Parts 1A, 2 and 3 (unseparated) to you when you leave. Detach Part 1A and keep it safe as you will be unable to obtain a copy. You may need the information shown on Part 1A when completing a tax return. • When you go to a new job give parts 2 & 3 of the form P45 to your new employer, or you will have tax deducted using the emergency code and may pay too much tax. • If you do not want your new employer to know the details on this form, send it to tax office immediately with a letter saying so and giving the name and address of your new employer. The tax office can make special arrangements, but you may end up paying too much tax for a while as a result.
