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.
In practice
Real-world examples.
Example
A freelance designer bought a high-end workstation for 3,000 pounds. After claiming tax relief, its remaining tax value was 1,800 pounds. When sold for 1,000 pounds, a balancing allowance of 800 pounds applies.
Example
A local bakery sold its old delivery van for 4,000 pounds when its official tax value was 6,500 pounds. The business can claim a balancing allowance of 2,500 pounds to cover the difference.
Example
A small design agency closed an office and disposed of its remaining office furniture for 500 pounds against a tax value of 2,000 pounds, resulting in a 1,500 pound balancing allowance.
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
Balancing Allowance = Tax Written-Down Value minus Disposal Proceeds
Example:
- Tax Written-Down Value = 5,000 pounds
- Disposal Proceeds = 2,000 pounds
- Balancing Allowance = 5,000 - 2,000 = 3,000 pounds deduction against profits.Case study
Seen in the real world.
GreenScape Garden Services, a small landscaping firm, purchased a specialised hedge trimmer for 4,500 pounds. Over two years, the business claimed capital allowances, reducing the official tax value of the trimmer down to 2,500 pounds. Unfortunately, the motor burned out completely in the third year, and the machine was sold for scrap metal for just 200 pounds.
When preparing the end-of-year accounts, the company accountant noticed a clear gap. The business had only claimed 2,000 pounds in tax relief, but the equipment actually lost 4,300 pounds in value due to the sudden breakdown. To correct this, the accountant claimed a balancing allowance of 2,300 pounds, which is the remaining tax value of 2,500 pounds minus the 200 pounds scrap proceeds.
This balancing allowance was deducted directly from GreenScape Garden Services' taxable profits for that year. As a result, the business paid less corporation tax, offsetting the unexpected financial loss of the broken equipment and keeping their cash flow stable.
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.
