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.

Real-world examples across industries

Professional services / consultancy

A consultancy buys laptops and monitors for two new starters, invoiced at £2,160 (£1,800 net). The entry is a debit of £1,800 to 0030 (Office Equipment), a debit of £360 to 2201, and a credit of £2,160 to 2100. IT kit like this is depreciated over a relatively short useful life — say 3 years, reflecting how quickly laptops age — giving an annual charge of £600: debit £600 to code 8004, credit £600 to 0031 (Office Equipment Depreciation). For a firm that owns no vehicles, plant or freehold property, this pair of codes can be the largest — sometimes the only meaningful — entry on the whole fixed asset register.

Manufacturing

A manufacturer buys office PCs and a printer for the admin team, invoiced at £1,800 (£1,500 net) — a debit of £1,500 to 0030, a debit of £300 to 2201, and a credit of £1,800 to 2100. Depreciated over 4 years, the annual charge is £375: debit £375 to 8004, credit £375 to 0031. The bookkeeping is identical to the consultancy above, but here it's a rounding error next to the depreciation running through 0021 (Plant/Machinery Depreciation) on the production line — the same entry can be financially significant for one business and barely noticed by another.

Growing tech or creative agency

An agency refreshes its laptop fleet after three years, scrapping a batch that originally cost £4,000 and has, by this point, been depreciated down to a net book value of nil — the £4,000 balance in 0031 exactly matches the £4,000 original cost still sitting in 0030. Because there's no resale value and nothing outstanding to write off, clearing the disposal is simply a debit of £4,000 to 0031 and a credit of £4,000 to 0030, with no profit or loss to recognise and no VAT involved. Agencies that refresh equipment on a fixed cycle like this often find the disposal timing lines up neatly with the depreciation schedule for exactly this reason.

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.
