What it means
When a business buys everyday items like computers, delivery vans, or office desks, it needs to record that spending. For financial reporting, companies use depreciation to spread the cost over time.
However, tax authorities do not always accept this accounting depreciation when calculating how much corporation tax you owe. Instead, they provide their own set of rules known as capital allowances.
Capital allowances matter because they directly reduce your taxable profits. By claiming these allowances, you pay less tax in the year you invest in your business, which leaves more cash available for day-to-day operations.
Different types of assets qualify for different rates, meaning some items can be written off completely in the first year, while others must be claimed gradually over many years. In practice, you calculate your capital allowances at the end of your financial year and deduct them from your profit before working out your final tax bill.
You must keep detailed purchase receipts and asset registers to prove what you bought and when. Understanding these rules helps managers time their big purchases strategically to maximise tax relief.
Getting this right requires careful categorisation of your spending. Some investments qualify for special first-year incentives, while others fall into standard pools where a fixed percentage is written off annually.
Working closely with your accountant ensures you claim the correct amount without falling foul of local tax regulations. Think of capital allowances like a special supermarket discount for business tools.
Just as a voucher lets you pay less at the checkout for buying in bulk, capital allowances let you pay less tax for investing in your business future.
In practice
Real-world examples
Example 1
TechStart, a digital agency, buys five new computers for $5,000. Through capital allowances, it deducts the full cost from its profits this year. At an illustrative tax rate of 20%, that saves $1,000 in tax and leaves extra cash for the next project.
Example 2
Metro Bakery purchases a delivery van for $20,000. It claims capital allowances on the vehicle, reducing its taxable profits and keeping extra cash inside the business for fuel and repairs. Because vans fall into a standard pool, the bakery claims a fixed percentage each year rather than the whole cost at once.
Example 3
Apex Manufacturing invests $100,000 in heavy factory machinery. It claims writing down allowances over several years to steadily reduce its corporate tax burden as the equipment ages. The finance manager keeps an asset register showing the purchase date and cost of each machine, so the claim can be proved if the tax authority asks.

Formula
Calculation
Annual Allowance = Opening Pool Value x Allowance Rate
Tax Saving = Allowance x Tax Rate
Worked example, using an illustrative writing down rate of 18% and a tax rate of 25% (both are set by the tax authority and change from time to time).
- Year 1: the general equipment pool is worth $10,000 at the start of the year, so the allowance = $10,000 x 18% = $1,800
- Tax saving in year 1 = $1,800 x 25% = $450
- The pool carried forward = $10,000 - $1,800 = $8,200
- Year 2 allowance = $8,200 x 18% = $1,476, saving $369 in tax, and the pool carried forward is $6,724
Selling an asset. Suppose the business sells all of the pooled equipment for $8,000 when the pool is worth $6,724. The $1,276 by which sale proceeds exceed the pool value is a balancing charge, so $1,276 is added back to taxable profit, which costs $1,276 x 25% = $319 in tax.Case study
Seen in the real world
This is a fictional, illustrative scenario. GreenLeaf Logistics, a mid-sized courier firm, decided to modernise its operations to support business growth. The management team purchased three electric delivery vans for a total of $90,000 and fitted out a new regional depot with energy-efficient LED lighting systems costing $15,000. Working with its finance team, GreenLeaf reviewed the relevant tax rules.
For the vans, it used first-year allowances, which allowed it to deduct the entire $90,000 from its taxable profits in the year of purchase. For the lighting system, which qualified under energy-saving rules, it applied specific green allowances. By properly claiming these capital allowances, GreenLeaf Logistics reduced its taxable profit for the year by $105,000. At an illustrative corporate tax rate of 19%, this generated an immediate cash saving of about $19,950.
The retained cash was subsequently used to hire two new office administrators. The finance director also noted that the allowances brought tax relief forward rather than creating it from nothing. Had the vans been written off through ordinary accounting depreciation over five years, the deduction would have been $18,000 a year, and the tax saving would have arrived in five slices instead of one. This proved that understanding capital allowances directly supports smart operational planning and business expansion.
Watch out
Common mistakes
- Assuming accounting depreciation and capital allowances are the exact same thing.
- Forgetting to claim allowances on smaller items hidden within general overhead invoices.
- Failing to keep accurate purchase receipts and asset registers for tax inspections.
Questions
People also ask
Are capital allowances the same as depreciation?
No. Depreciation is an accounting estimate used in your financial reports, whereas capital allowances are official deductions set by the government to calculate your taxable profit.
Do I need receipts to claim capital allowances?
Yes. You must keep proper records, invoices, and receipts to prove you own the assets and to show when you bought them in case the tax authority reviews your return.
What happens if I sell an asset I claimed allowances on?
If you sell the item for more than its remaining tax value, you may have to pay tax on the difference, known as a balancing charge.
