The Fixed Asset Register: Tracking What You Own and Getting Depreciation Right

At the end of every year a line called "furniture and equipment" shows up in the books, carrying a number nobody can fully explain. Laptops sold two years ago are still listed. A replaced vehicle was never written off. Air conditioners were bought and never entered. The result is a balance sheet holding assets that do not exist.

What counts as a fixed asset

A fixed asset is something you buy to use in operations rather than resell, and whose useful life runs beyond one year: computers, furniture, equipment, vehicles, fit-out works and some software. Anything else is an expense of the year of purchase.

The dividing line is your capitalisation threshold: an amount you decide and write into your finance policy. Any purchase above it that meets the useful-life test enters the register; anything below is expensed. A small business might set two thousand riyals, a larger one five thousand. There is no single correct number, but one common mistake: no written threshold at all, so a three-hundred-riyal chair gets capitalised over five years while a fifteen-thousand-riyal machine is booked as maintenance.

What the register must hold

An asset register is not a purchase list. It is a card per asset, followed from purchase to disposal. The minimum fields:

Field	Why it matters
Asset number and physical tag	The only link between the paperwork and the object
Description and serial number	Stops ten identical devices blurring into one
Purchase date, cost and invoice	The basis for depreciation and later review
Location, branch and cost centre	Puts the charge on the unit that benefits from it
Responsible employee or department	Makes custody clear when someone leaves
Useful life and depreciation method	Keeps the monthly calculation free of judgement calls
Expected residual value	Stops an asset reaching zero while it still resells
Accumulated depreciation and net book value	What you read on the balance sheet
Status: in service, under repair, disposed	Separates working assets from idle

A register inside your business system, not a side spreadsheet, posts the monthly entry itself and links each asset to its invoice and cost centre.

Depreciation without the complexity

Straight line

This suits most assets in a small or mid-sized business: spread the cost evenly across the useful life. The formula is cost minus residual value, divided by the years.

An illustration: a machine costing 12,000 riyals, life four years, residual value zero. Annual depreciation is 3,000 riyals — 250 a month charged to expense and taken off book value.

Reducing balance

This loads more depreciation into the early years, fitting assets that lose value fast. Practical rule: use straight line unless you can explain a reason to your accountant, and never switch methods year to year.

Useful lives are estimates, not facts. Put them in a written policy rather than leaving each person to decide.

The physical count

At least once a year, walk the sites with the register in hand and match three things: tag, location, condition. Most differences surface on that walk — something that left and was never written off, or arrived and was never recorded.

Whoever counts should not be the person who buys or holds custody. Document every difference and post it with management sign-off, not a silent edit to a file.

Disposal and sale

Removing an asset is not deleting a row. On sale or scrapping, the cost and its accumulated depreciation come off together, and the difference between proceeds and net book value lands in the income statement as a gain or loss. An asset sold for ten thousand with a book value of six thousand shows a four-thousand gain. If the sale falls within scope of VAT, it is invoiced like any other sale.

Tax and zakat

Depreciation in your books is one thing; depreciation accepted for income tax purposes is another, as the regulations sort assets into groups with their own treatment. Do not assume the two match — check the published texts on zatca.gov.sa, or ask your certified accountant, before you file.

Just as important: keep the purchase invoice, proof of payment and disposal record. A register with no attachments is hard to defend under review.

Common mistakes

• Recording the invoice amount only, ignoring delivery and installation costs.
• Capitalising routine maintenance, or expensing an upgrade that extends an asset's life.
• Leaving fully depreciated assets in the schedules years after they are gone.
• Not linking assets to a branch or cost centre, so branch profitability stays incomplete.
• Relying on one file edited by one person, with no review or backup.
• Not updating location and custodian when an asset moves.

Year-end checklist

• The capitalisation threshold is written, approved and applied.
• Every asset carries a tag, and that number exists in the register.
• A physical count was done and its differences documented.
• Sold or scrapped assets were written off, gain or loss shown.
• Monthly depreciation is posted for every month with no gaps.
• Accumulated depreciation agrees with the general ledger.
• Purchase and disposal documents are linked to each asset.
