Motor Vehicles Depreciation

This is the accumulated depreciation account for Motor Vehicles — a contra-asset account sitting alongside the original asset cost. It normally carries a credit balance, increased each year by the depreciation charge (posted as an expense to code 8003).

Real-world examples

Logistics and distribution

A distribution business depreciates its delivery vans over a relatively short useful life — say 5 years — reflecting the high mileage and wear of daily use, giving an annual charge of, say, £5,000 per van. The entry is a debit of £5,000 to the depreciation charge code in Overheads & Depreciation and a credit of £5,000 to 0051 (Motor Vehicles Depreciation). No VAT is involved, as with any depreciation entry.

Lower-mileage company car

A business running a single, lightly-used company car assumes a longer useful life — perhaps 7-8 years — giving a smaller annual charge relative to cost than a van doing daily delivery rounds. The mechanics are identical (debit the depreciation charge code, credit 0051); only the useful-life assumption, driven by how hard the vehicle is actually used, differs.

Commonly confused with

Code 0051 (Motor Vehicles Depreciation) is easy to mix up with code 0050 (Motor Vehicles). Code 0051 is the accumulated depreciation — a contra-asset that only ever moves at the year-end depreciation run — while 0050 is the original asset cost, which only changes when an asset of that type is actually bought or sold. Posting to the wrong one understates the asset's net book value without anyone noticing until the next audit.

What a mis-posting here costs you

Posting motor vehicles depreciation-related spend to the wrong Fixed Assets code doesn't change the total value of assets on the balance sheet, since it's still capitalised either way — but it does distort the fixed asset register and the depreciation schedule that runs off it, which is usually what alerts an accountant that something's misclassified at the year end.
