How to Manage Fixed Assets and Depreciation in Xero

What Are Fixed Assets and Why They Matter

A fixed asset is something your business owns and uses to generate income over more than one year. Think work vehicles, machinery, computers, tools, office furniture, and fit-out. Unlike a box of printer paper, which you expense in full the moment you buy it, a fixed asset is recorded on your balance sheet and its cost is spread across its useful life through depreciation.

Getting this right matters for two reasons. The first is accuracy. If you expense a $12,000 ute in one hit, your profit and loss statement is distorted and your balance sheet understates what the business actually owns. The second is tax. Depreciation is a legitimate deduction, and the way you treat an asset affects how much you can claim and when. The Australian instant asset write-off rules, in particular, can let eligible small businesses deduct the full cost of an asset immediately rather than over several years.

Xero has a built-in fixed assets register that handles all of this. Most small business owners never open it, which is a mistake. Here is how to use it properly.

Setting Up the Fixed Assets Register

Before you register your first asset, set up the register so depreciation posts to the right accounts.

1. Go to Accounting, then Advanced, then Fixed Assets.
2. Click the Settings tab.
3. Confirm your asset accounts. You need at least three accounts in your chart of accounts: a fixed asset account (where the asset cost sits), an accumulated depreciation account, and a depreciation expense account.
4. Set the start date for your fixed asset register. This is usually the start of the financial year in which you began tracking assets.

Xero comes with default accounts for plant and equipment, motor vehicles, and office equipment, but you can add asset types to suit your business. A tradie might want a dedicated tools and equipment type, while a cafe might want a kitchen equipment type.

Registering a New Asset

When you buy a fixed asset, the purchase first appears as a normal transaction in your bank feed or as a bill. You code that transaction to a fixed asset account rather than an expense account. From there:

1. Go to Accounting, then Fixed Assets, then the Draft tab. Xero automatically pulls through any transaction coded to a fixed asset account.
2. Click the draft asset to open it.
3. Fill in the asset details: a name, an asset number, the purchase date, and the purchase price.
4. Choose the asset type, which sets the default depreciation method and rate.
5. Set the depreciation start date, the depreciation method, the rate or effective life, and the cost limit if one applies.
6. Click Register.

Once registered, the asset moves to the Registered tab and is ready to depreciate.

Choosing a Depreciation Method

Xero supports the two methods used by most Australian businesses:

Straight line (prime cost). The asset depreciates by the same amount every year across its useful life. A $5,000 asset with a five-year life depreciates by $1,000 each year. This method is simple and predictable.

Diminishing value. The asset depreciates by a fixed percentage of its remaining value each year, so the deduction is larger in the early years and smaller later on. This better reflects how assets like vehicles and technology lose value quickly when new.

The Australian Taxation Office publishes effective life schedules for most asset types, and your accountant can confirm which method and rate to use. The method you choose affects the timing of your deductions, not the total amount claimed over the asset's life.

Running Depreciation

Depreciation is not automatic. You need to run it, usually at month end or year end:

1. Go to Accounting, then Fixed Assets.
2. Click Run Depreciation.
3. Review the depreciation period and the assets included.
4. Confirm to post the depreciation journals.

Xero creates the journal entries for you, debiting depreciation expense and crediting accumulated depreciation. Once posted, the depreciation appears on your profit and loss statement and the asset's written-down value updates on your balance sheet. Run depreciation consistently so your reports stay accurate throughout the year rather than only at tax time.

The Instant Asset Write-Off and Pooling

Many small businesses do not depreciate assets in the traditional way at all. Under the instant asset write-off, eligible small businesses can immediately deduct the full cost of an asset that falls under the relevant threshold, rather than depreciating it over years. Assets above the threshold may go into a small business depreciation pool and depreciate together at a set rate.

In Xero, you can handle an instant write-off by coding the purchase straight to an expense account on the advice of your accountant, or by registering the asset and recording an immediate full depreciation. The thresholds and eligibility rules change from year to year, so always confirm the current rules and the right treatment with your accountant before lodging. Recording it the wrong way can mean a missed deduction or an incorrect balance sheet.

Disposing of an Asset

When you sell, scrap, or trade in a fixed asset, you need to dispose of it in Xero so it stops depreciating and any gain or loss is recorded:

1. Go to Accounting, then Fixed Assets, then the Registered tab.
2. Open the asset and click Options, then Dispose.
3. Enter the disposal date and the sale proceeds, if any.
4. Choose the account for the gain or loss on disposal.
5. Confirm.

Xero calculates the difference between the sale price and the written-down value, then posts a gain or loss. This keeps your balance sheet clean and ensures you are not still depreciating an asset you no longer own.

Tips for Keeping Your Asset Register Clean

• Register assets as you buy them, not in a panic at year end. Draft assets sitting unregistered distort your balance sheet.
• Keep purchase documentation. Attach the invoice to the asset record in Xero so the supporting paper is always one click away.
• Reconcile the register to your balance sheet at year end. The total of your registered assets should match your fixed asset account balances.
• Talk to your accountant about method and thresholds before registering anything significant. The treatment affects your tax position.

For businesses that want their underlying transactions coded correctly in the first place, SortBooks automates categorisation and flags when a purchase looks like a capital asset rather than a regular expense. Clean coding makes the fixed asset register far easier to maintain, because the right transactions land in the right accounts from the start.
