What it means
When you run a business, you buy equipment, computers, and vehicles that gradually lose value. Tax authorities let you deduct a portion of this cost each year through capital allowances.
Over time, the total tax deductions you claim should match the actual loss in value of that equipment. However, things do not always go to plan.
If you sell an asset, or stop using it for business, you might find that you have not claimed enough tax relief yet. The actual market value or sale price might be lower than the remaining amount left in your tax pool.
When this happens, the tax authority gives you a top-up deduction known as a balancing allowance. This matters because it protects your cash flow.
If an asset becomes obsolete or fails prematurely, you are not left out of pocket for the unrealised tax relief. The balancing allowance accounts for the shortfall in your final tax return for that asset, reducing your overall taxable profit for the year.
In practice, your accountant calculates this by comparing the disposal proceeds against the tax written-down value of the asset. If the proceeds are lower, the difference is your balancing allowance.
It is a helpful financial adjustment that ensures businesses only pay tax on their true net economic gains. Imagine buying a prepaid train ticket for a year-long pass, but you only use it for six months before the train line closes.
The transit company gives you a refund for the unused value. A balancing allowance works the same way for tax.
In practice
Real-world examples
Example 1
A freelance designer bought a high-end workstation for $3,000. After claiming tax relief, its remaining tax value was $1,800. When the workstation was sold for $1,000, a balancing allowance of $800 applied, which reduced that year's taxable profit by the same amount.
Example 2
A local bakery sold its old delivery van for $4,000 when its official tax value was $6,500. The business can claim a balancing allowance of $2,500 to cover the difference. Because the van also had a lower accounting book value, the baker's bookkeeper had to be careful to use the tax figure, not the accounting figure.
Example 3
A small design agency closed an office and disposed of its remaining furniture for $500 against a tax value of $2,000, resulting in a $1,500 balancing allowance. The agency's accountant included it in the final return for the office lease, so the loss was relieved in the same year as the closure.
Think of it
Imagine buying a prepaid train ticket for a year-long pass, but you only use it for six months before the train line closes. The transit company gives you a refund for the unused value. A balancing allowance works the same way for tax.
Formula
Calculation
Tax Written-Down Value = Original Cost minus Capital Allowances Claimed to Date
Balancing Allowance = Tax Written-Down Value minus Disposal Proceeds (only when proceeds are lower than the tax written-down value)
Worked example 1:
- Tax Written-Down Value = $5,000
- Disposal Proceeds = $2,000
- Balancing Allowance = $5,000 - $2,000 = $3,000, deducted against profits.
Worked example 2, including the tax saving. A manufacturer buys a machine for $10,000 and claims $6,000 of capital allowances over the first years, so the tax written-down value is $10,000 - $6,000 = $4,000. The machine fails and is sold for scrap at $1,500. The balancing allowance is $4,000 - $1,500 = $2,500. If the company's tax rate is 25% (an illustrative rate), the allowance saves $2,500 x 25% = $625 of tax.
Note that rules differ by country and by how assets are grouped. In some systems assets sit in a shared pool and a balancing allowance only arises when the pool is closed or the business stops trading, so always confirm the local treatment with your accountant.Case study
Seen in the real world
This is a fictional, illustrative scenario. GreenScape Garden Services, a small landscaping firm, purchased a specialised hedge trimmer for $4,500. Over two years, the business claimed capital allowances, reducing the official tax value of the trimmer down to $2,500. Unfortunately, the motor burned out completely in the third year, and the machine was sold for scrap metal for just $200.
When preparing the end-of-year accounts, the company accountant noticed a clear gap. The business had only claimed $2,000 in tax relief, but the equipment had effectively lost $4,300 in value due to the sudden breakdown. To correct this, the accountant claimed a balancing allowance of $2,300, which is the remaining tax value of $2,500 minus the $200 scrap proceeds. This allowance was deducted directly from GreenScape's taxable profits for that year.
As a result, the business paid less corporation tax, offsetting the unexpected loss and keeping its cash flow stable. The owner took one lasting lesson from the episode. GreenScape now keeps a simple fixed asset register showing cost, allowances claimed and tax written-down value for every machine, so that any future disposal can be checked against the correct figure straight away. The register also lets the owner see in advance how much tax relief a planned sale or write-off will release.
Watch out
Common mistakes
- Confusing the accounting book value with the tax written-down value when calculating the allowance.
- Forgetting to claim the allowance entirely when selling business assets at a loss.
- Mistakenly applying a balancing allowance when the asset was actually sold for a profit.
Questions
People also ask
What happens if I sell the asset for more than its tax value?
If you sell it for more, you will likely face a balancing charge, which adds to your taxable profits instead of giving you a deduction.
Do I need to keep records of asset sales for this?
Yes, you must keep invoices, receipts, and records of the sale price to prove the exact difference to the tax authority.
Is a balancing allowance paid as cash to my business?
No, it is a tax relief that reduces your taxable profit, which ultimately lowers the amount of tax you have to pay.
