Office Equipment and Its Depreciation: Codes 0030 & 0031

Computers, printers, photocopiers and other office kit are fixed assets like any other — bought to use for years, not to resell. Sage keeps the original cost separate from the depreciation that gradually writes it down, so both figures stay visible on the balance sheet.

The two codes, and what each one holds

Code 0030 — Office Equipment records the purchase cost of computers, printers and other office machinery bought for long-term use. It's a Fixed Assets code and normally carries a debit balance, increased when new equipment is bought and reduced only on disposal.

Code 0031 — Office Equipment Depreciation is the accumulated depreciation account sitting alongside 0030 — a contra-asset account that normally carries a credit balance. Each year's depreciation charge (posted as an expense to code 8004) increases this credit balance, reducing the equipment's net book value without touching the original cost in 0030.

A worked example

Say a business buys a batch of new laptops and a photocopier for £6,000 (excluding VAT), depreciated over 3 years on a straight-line basis.

Purchase (code 0030): £6,000 debited as the asset cost.

Annual depreciation charge (code 8004): £6,000 ÷ 3 = £2,000 a year, debited as an expense.

Accumulated depreciation (code 0031): credited £2,000 a year — after two years the credit balance reaches £4,000, so the net book value has fallen to £2,000, even though code 0030 still shows the original £6,000.

Why this matters day to day

Office equipment tends to be replaced fairly quickly, so it's easy for a fixed asset register to fill up with old laptops and monitors that are long gone. Disposing of scrapped equipment without also clearing its accumulated depreciation from 0031 leaves both codes overstated, making the fixed assets section of the balance sheet look bigger than the equipment actually in use.
