Calculate what you did at 45p/mile, take off that the difference between your total fuel spend and the amount showing on your P11D. That is what you can claim as the business mileage in your personal car less the fuel you have not had to pay for.

My total annual mileage was 9,481. My business miles were 619, therefore private mileage was 8,862. Therefore 8,862/9,481 =93.5%. Total fuel cost was £1,777.47 x 93.5% =£1,661.93. This figure was included in my P11D for BIK

I can provide an update on your actual claim potential via the 45 pence per mile tax relief when I get home this evening. Not so easy to do on the phone on the train.

So 1,777.47 - 1,661.93 = 115.54 business fuel spend has already been fully covered.

619 x 0.45 = £278.55 would cover all vehicle costs incl fuel, insurance, wear and tear.

The fuel part of that is as above, leaving 278.55 - 115.54 = £163.01 for insurance, wear & tear.

So you could claim back the tax on £163.01.

The OP receives a car allowance which is treated for tax purposes as additional salary and subject to income tax plus NI accordingly.

The OP covered 619 business miles so the maximum relief is at 45 pence per mile, so £278.55.

The OP already received £1,777.47 - £1,661.93 = £115.54.

That leaves a balance (£278.55 - £115.54) of £163.01 against which the OP could claim tax relief.

For a 20% tax payer, that relief is worth £32.60. Worth more for higher tax bands. Might be very significant if the OP's taxable income is near one of the cliff-edge thresholds.
