Disposing of Assets and Balancing Charges

When you sell or dispose of an asset you've previously claimed capital allowances on, there are important tax consequences. You may need to add money back to your profits (a balancing charge) or claim additional relief (a balancing allowance). Understanding how this works ensures you report the disposal correctly and avoid unexpected tax bills.

What counts as disposing of an asset

You dispose of an asset when you:

• Sell it
• Give it away as a gift or transfer it to someone else
• Swap it for something else
• Receive compensation for it (such as an insurance payout if it's lost or destroyed)
• Start using it for non-business purposes
• Close your business

You don't need to include disposals in your calculations if you donate the asset to a charity or community amateur sports club (CASC).

Working out the disposal value

The disposal value is usually the amount you sold the asset for.

However, you must use the market value (what you'd reasonably expect to sell it for) if you:

• Gave it away
• Kept it to use outside your business
• Sold it for less than its worth to someone who cannot claim capital allowances

Special rules when selling for more than original cost

If you sell an asset for more than you originally paid, you can only deduct the original cost from your pool, not the higher sale price.

There's a special rule if a connected person sold the asset to you for less than it cost them. In this case, deduct whichever is smaller: the amount you sell it for, or the amount it originally cost them.

Connected people include your spouse, civil partner, relatives, business partners and their relatives. For companies, you're connected if you control both companies or are part of a group controlling both.

If you originally claimed 100% relief

When you first bought the asset, you may have claimed 100% of the cost through the Annual Investment Allowance (AIA) or first-year allowances.

If you have nothing in the relevant pool:

Add the full disposal value to your profits on your tax return. This is called a balancing charge, and you'll pay tax on this amount.

If you have a balance in the relevant pool:

Deduct the disposal value from that pool. If the disposal value exceeds the pool balance, add the difference to your profits as a balancing charge.

If there's still a balance left in your pool after deducting the disposal value, you can continue claiming writing down allowances on that remaining balance.

If you originally used writing down allowances

If you claimed writing down allowances (the standard annual percentage reductions) when you bought the asset, deduct the disposal value from the pool you originally added it to.

Use the remaining pool balance to calculate your next writing down allowances.

For single asset pools:

Claim any amount left in the pool as a capital allowance on your tax return. This leftover amount is called a balancing allowance—it provides additional tax relief.

If disposal value exceeds pool balance:

Add the difference to your profits as a balancing charge.

Important limitation:

You can only claim a balancing allowance from your main or special rate pool when you close your business. However, balancing charges can arise in any pool in any year.

What are balancing charges and balancing allowances?

Balancing charge: When the disposal value is higher than your remaining pool balance, you add the difference to your profits. This effectively claws back some of the tax relief you previously received. You'll pay tax on this amount.

Balancing allowance: When you dispose of an asset in a single asset pool and there's money left over, you can claim this remaining amount as additional tax relief. This reduces your taxable profit.

These mechanisms ensure you receive the correct amount of tax relief over the asset's life—no more, no less.

Special rules for recent allowances

Different disposal rules apply if you claimed:

• Super-deduction or special rate first-year allowances (these were temporary reliefs for companies)
• Full expensing or 50% first-year allowances

These schemes have their own disposal calculations. HMRC provides separate guidance if you've used these allowances.

When you close your business

In the year you close your business, you enter either a balancing charge or a balancing allowance on your tax return instead of claiming regular capital allowances.

This final adjustment ensures all capital allowances are properly settled. For main and special rate pools, this is the only time you can claim a balancing allowance.

Reporting disposals

Include the disposal value in your calculations for the accounting period when you sell or dispose of the asset. Report balancing charges and balancing allowances on your Self Assessment tax return in the capital allowances section.

Make sure you keep records of:

• The original cost of the asset
• When and how you disposed of it
• The disposal value
• Which pool it was in
• Previous capital allowances claimed

These records will help you calculate the correct balancing charge or allowance and support your tax return if HMRC asks questions.
