You bought a laptop for your business. A desk. Maybe a car. Perhaps some office equipment that cost a few thousand dollars.
You paid for these things. You recorded the expense. Job done, right?
Not quite.
These are not expenses in the traditional sense. They are fixed assets — and how you treat them in your books makes a significant difference to your financial statements, your tax position and your understanding of what your business is actually worth.
This guide explains everything you need to know about fixed assets, written in plain English. No accounting degree required.
What is a Fixed Asset?
A fixed asset is any physical item your business owns that has a useful life of more than one year and is used to generate income — not bought for resale.
The key distinction is this:
Stock or inventory — items you buy to sell to customers. These are current assets.
Fixed assets — items you buy to use in the business over time. These are long-term assets.
Common examples of fixed assets for small businesses include computers and laptops, office furniture and fittings, motor vehicles, machinery and equipment, leasehold improvements such as renovation works, and office equipment like printers and photocopiers.
What is NOT a fixed asset? Consumables like paper, pens and printer ink. These are expenses because they are used up immediately.
Why Fixed Assets Are Treated Differently
When you buy a box of pens for $10, you record it as an expense immediately. The $10 is gone.
When you buy a laptop for $3,000, you do not record it as a $3,000 expense in the month you bought it. Instead, you spread the cost across the years the laptop will be used.
This is because the laptop will benefit your business for three, four or five years — not just the month you purchased it. Recording the full cost as an immediate expense would distort your profit figures significantly.
This spreading of cost over time is called depreciation.
What is Depreciation?
Depreciation is the process of allocating the cost of a fixed asset across its useful life.
Think of it this way. You buy a car for $50,000. You expect it to last five years. Each year, a portion of that $50,000 is recognised as an expense — not the full amount upfront.
There are two common depreciation methods:
Straight-Line Method (SL)
The asset loses the same amount of value every year.
Formula: Annual depreciation = Cost ÷ Useful life in years
Example: $50,000 car with a 5-year life = $10,000 per year
Reducing Balance Method (RB)
The asset loses a fixed percentage of its remaining value each year. Depreciation is higher in the early years and reduces over time.
Example: $50,000 car at 20% reducing balance
Year 1: $10,000
Year 2: $8,000
Year 3: $6,400
Different types of assets are typically depreciated using different methods depending on how quickly they lose value in real life.
Key Terms You Need to Know
Cost — the original purchase price of the asset including any costs directly related to bringing it into use, such as delivery or installation.
Useful Life — how long you expect the asset to be useful to the business. This is an estimate, not a fixed rule.
Depreciation Rate — the percentage used to calculate annual depreciation.
Accumulated Depreciation — the total depreciation charged on an asset from the date of purchase to the current date.
Net Book Value (NBV) — the current value of the asset in your books. This is Cost minus Accumulated Depreciation. It is not the market value — just the accounting value.
Disposal — when you sell, scrap or write off an asset. At disposal, you stop depreciating the asset and remove it from your books.
One Asset That Is NEVER Depreciated
Land.
No matter how much land costs, you do not depreciate it. Land does not wear out. It does not become obsolete. It does not have a finite useful life.
This is one of the most commonly confused areas of fixed asset accounting — even among business owners who have been running their companies for years.
Buildings sitting on the land are depreciated. The land itself is not.
Why Every Business Needs a Fixed Assets Register
A fixed assets register is a record of every fixed asset your business owns. It tracks the purchase date, cost, depreciation method, accumulated depreciation, net book value and disposal date for each asset.
Without a fixed assets register, you have no way to know:
What assets your business actually owns
What those assets are currently worth on the books
How much depreciation to charge each year
Which assets have been fully depreciated
Which assets have been disposed of
At year end, your accountant will ask for your fixed assets register to prepare your financial statements. If you cannot provide one, they will have to rebuild it from scratch — at your expense.
More importantly, your financial statements will be wrong without it. Understated depreciation means overstated profit. Overstated profit means overstated tax.
What Should Be In a Fixed Assets Register?
At minimum, your fixed assets register should capture:
Asset description and code
Category (e.g. Computer & IT, Motor Vehicles, Furniture)
Purchase date and cost
Depreciation method and rate
Monthly or annual depreciation charge
Accumulated depreciation to date
Net book value
Disposal date and details if applicable
A well-structured register updates automatically as you change the schedule date, so you can see the position of your assets as at any point in time — not just today.
Common Mistakes Small Business Owners Make
Expensing everything immediately. Buying a $5,000 piece of equipment and recording it as a full expense in the month of purchase inflates your costs and understates your profit. Large purchases should generally be capitalised as fixed assets and depreciated.
Never updating the register. A fixed assets register that has not been updated in two years is worse than useless. It gives you a false picture of what your business owns.
Not recording disposals. When you sell or scrap an asset, it must be removed from your register. Assets that have been disposed of but are still sitting on your books inflate your asset values and continue generating depreciation charges.
Confusing net book value with market value. An asset with a net book value of $0 in your books might still be worth something in the market — and vice versa. Net book value is an accounting figure, not a valuation.
Depreciating land. As mentioned above — never depreciate land. It is a surprisingly common mistake.
How to Get Started
If you do not have a fixed assets register, start by making a list of everything your business owns that cost more than a threshold amount — say $500 — and has a useful life of more than one year.
For each item, gather the purchase date, original cost and any details about how it has been depreciated so far.
From there, you can set up a proper register that tracks everything automatically going forward.
The earlier you start, the easier it is. Trying to rebuild years of asset history at once is one of the most painful exercises in accounting — and one that is entirely avoidable.
The Bottom Line
Fixed assets are not just big purchases. They are a core part of your balance sheet and your profit figures.
Getting them right means your financial statements are accurate. Your depreciation charges are correct. Your net asset values make sense. And when your accountant, your bank or a potential investor looks at your numbers, they reflect reality.
Getting them wrong means years of corrections, inflated profits, incorrect tax filings and a financial picture that does not tell the truth about your business.
A fixed assets register is not a luxury. For any business that owns meaningful assets, it is a necessity.
