Company Car Tax Calculation

Mercedes-Benz S-Class S 63 E Performance Night Edition AMG SPEEDSHIFT MCT 9G

A company car driver can expect to pay vehicle benefit tax If the company pays for the use of fuel on private journeys, tax on fuel benefit will also be applied. Use our fuel benefit check tool to give you an indication of what this would look like.

For a monthly paid car driver on the PAYE system with the correct tax code, one twelfth of the appropriate amount of tax will be deducted from income via the monthly payroll. The car benefit is added to your income for tax purposes. For an individual already close to the threshold for higher rate tax, some will be taxed at 20 percent, and some at 40 percent. The P11D value is fixed for the life of the car according to the new list price when first registered, but other rates may change.
