You pay tax on company benefits like cars, medical insurance and living accommodation.
You’ll pay more tax and your take home pay will reduce if:
- you start getting a company benefit
- the value of your company benefit increases
You’ll pay less tax and your take home pay will increase if:
- you stop getting a company benefit
- the value of your company benefit decreases

Check your details online
You can use the PAYE section of HMRC online services or the HMRC app to check:
- all your company benefits are shown in your PAYE Income Tax summary
- the value of each company benefit is correct in your tax-free amount calculation
Using the HMRC online service:
- Sign in to HMRC online services.
- Go to the ‘Pay As You Earn (PAYE)’ section.
- Select ‘check current tax year’ to view your PAYE Income Tax Summary for 6 April to 5 April.
- Select ‘view or update company benefits’.
Using the HMRC app
- Download the HMRC app.
- Go to the ‘Pay As You Earn (PAYE)’ section.

Update your details if they are wrong or missing
If your details are wrong or missing you can use the HMRC online services or the HMRC app to:
- add a missing company benefit
- tell us the amount of company benefit has changed
- tell us the start and end dates of your company benefits
If you have other details to update you can tell HMRC about:
- starting a new job
- having more than one job
- a change in your employment income
- a change to your pension income
Keeping your tax code up to date helps to make sure you pay the correct amount of tax. This makes it less likely you will pay too much or too little tax.
After you update your details
Not all changes you tell HMRC about will affect your tax code. We will tell your employer or pension provider if your tax code changes. Your next payslip should show your new tax code and any adjustments if you were paying the wrong amount of tax.
When you sign up for paperless updates you will get a message if your tax code changes. You can view these updates in the:
- messages section of your HMRC online account
- communication section of your HMRC app
