Almost every Singapore business owns assets it uses year after year: computers, machinery, office fit-outs, vehicles, or equipment. These are your fixed assets, and how you record, track, and depreciate them affects your balance sheet, your profit, and the tax you pay. Yet many SMEs manage them on a scrap of spreadsheet, or not at all, until an auditor or the taxman asks a question they cannot answer.
This guide explains what a fixed asset register is, how depreciation works, and how the two connect to your Singapore tax position. It rounds out our practical bookkeeping series alongside our guides on setting up a chart of accounts and reading your financial statements.
What Counts as a Fixed Asset
A fixed asset is something the business owns and uses to generate income over more than one year, rather than something bought to resell or consume quickly. Typical examples include office equipment and computers, furniture and fittings, plant and machinery, motor vehicles, and renovation works. Items that are used up within a year, or that cost very little, are normally treated as expenses rather than capitalised as assets. Many businesses set a sensible capitalisation threshold so that low-value purchases are simply expensed.
What a Fixed Asset Register Is
A fixed asset register is a detailed record of every fixed asset the company owns. It is the subledger that supports the single asset figure shown on your balance sheet, and it is one of the first things an auditor will ask to see. A useful register records the following for each asset.
| Field | Why it matters |
|---|---|
| Description and asset ID | Identifies the item and links it to a physical tag |
| Purchase date and cost | Starting point for depreciation and tax claims |
| Location and custodian | Supports physical verification and accountability |
| Useful life and depreciation method | Determines the annual depreciation charge |
| Accumulated depreciation and net book value | Shows the current carrying value |
| Disposal date and proceeds | Records gains or losses on sale |
Keeping the register current is not optional housekeeping. Singapore companies must maintain proper accounting records that explain their assets and transactions, and retain them for at least five years, as set out by IRAS. A tidy register also makes your annual close and audit dramatically faster.
How Depreciation Works
Depreciation spreads the cost of a fixed asset over the years it is used, matching the expense to the income it helps generate. Instead of taking the full cost as an expense in the year of purchase, you charge a portion each year. Two methods are common for SMEs.
Straight-line method
The cost, less any expected residual value, is divided evenly over the asset’s useful life. A computer costing 3,000 dollars with a three-year life is depreciated at 1,000 dollars per year. This is the simplest and most widely used method.
Reducing-balance method
A fixed percentage is applied to the asset’s remaining book value each year, so the charge is higher early on and tapers over time. This suits assets that lose value fastest when new. Whichever method you choose, apply it consistently and review useful lives periodically.
Depreciation Versus Capital Allowances
Here is a point that trips up many owners. The depreciation you record in your accounts is not deductible for Singapore income tax. Instead, the tax system gives you capital allowances, its own version of depreciation for qualifying assets. When you prepare your tax computation, accounting depreciation is added back to profit and capital allowances are claimed in its place.
Capital allowances can often be claimed over the asset’s useful life, over three years, or in a single year for low-value assets and certain equipment, giving you useful flexibility. We explain the mechanics, rates, and elections in detail in our guide to capital allowances under sections 19 and 19A. A well-kept fixed asset register is what makes an accurate capital allowances claim possible, and it feeds directly into your Estimated Chargeable Income and annual return.
Setting a Capitalisation Policy
A capitalisation policy is a simple written rule stating the minimum cost at which a purchase is treated as a fixed asset rather than an immediate expense. Without one, businesses either clutter the register with trivial items such as a 50-dollar stapler, or wrongly expense significant equipment. A common approach is to set a sensible threshold, apply it consistently, and expense anything below it. The right level depends on the size of your business, so choose a figure that keeps the register meaningful without capitalising items that are not worth tracking. Document the policy so it is applied the same way every year, which auditors and IRAS both value.
Common Fixed Asset Mistakes
Several errors recur in SME accounts. Expensing an asset that should be capitalised understates your balance sheet and can distort profit. Failing to remove disposed or scrapped assets leaves ghost items inflating the register and depreciation. Applying depreciation inconsistently, or forgetting it entirely for months, makes the accounts unreliable. Confusing accounting depreciation with tax capital allowances leads to incorrect tax computations. And neglecting the annual physical count means the register slowly drifts from reality. Each of these is easy to avoid with a maintained register and a fixed monthly routine as part of your close.
Disposals and Physical Verification
When you sell or scrap an asset, remove it from the register and record the difference between the sale proceeds and its net book value as a gain or loss. For tax, disposing of an asset on which capital allowances were claimed can trigger a balancing adjustment, so the disposal must be captured accurately. At least once a year, walk through the register and physically confirm the assets still exist and are where they should be. This simple check catches missing, obsolete, or double-counted items before they distort your accounts.
Get Your Fixed Assets in Order
The register also supports better business decisions beyond compliance. Knowing the age, cost, and remaining book value of your equipment helps you plan replacements, budget for capital expenditure, and decide whether to repair or replace an ageing asset. It can support insurance claims by evidencing what you owned and its value, and it gives lenders confidence when you seek financing secured on your assets.
A clean fixed asset register does more than satisfy the auditor. It gives you an accurate balance sheet, a defensible tax position, and a clear view of what you own and what needs replacing.
