You therefore need to set up a deferred tax liability in your accounts - to reflect the fact that in future years you will make a loss on the vehicle, but you won't get a tax deduction for the loss.
Assume: Buy car for 100. Tax rate 20%.
Year 1. Depreciation 20, Tax deduction 100. NBV c/fwd = 80; TWDV c/fwd = 0. Comparing these, the Deferred tax liability on the balance sheet ((80-0)*20%)=£16 so you book a deferred tax charge of 16.
Year 2. Depreciation 20, Tax deduction nil. NBV c/fwd = 60; TWDV c/fwd = 0. Comparing these, the Deferred tax liability on the balance sheet ((60-0)*20%)=£12 so you book a deferred tax credit of 4.
Year 3. Depreciation 20, Tax deduction nil. NBV c/fwd = 40; TWDV c/fwd = 0. Comparing these, the Deferred tax liability on the balance sheet ((40-0)*20%)=£8 so you book a deferred tax credit of 4.
Year 4 you sell it for 50. So (if we assume this gives you a balancing charge) you get a tax charge of 10 after bringing the proceeds into . You also have a deferred tax liability already on the balance sheet of 8 which you write back a credit for, giving you a net tax charge of 2 attached to an accounting profit of 10.
