Accountants Chester – Tax Tip No. 53

Tax and accounting rules are not identical and it is sometimes necessary to adjust the accounting profit to arrive at the profit for tax purposes. One area where the rules differ is in the write-off of capital expenditure.

For accounting purposes, depreciation is charged to the accounts so as to write off the asset over its useful economic life. This may, for example, be on a 33% reducing balance basis or on a 25% straight line basis.

By contrast, for tax purposes, relief for capital expenditure is given by way of capital allowances.

The capital allowances that are available depend on the nature of the asset, and there may be more than one possible claim. For example, qualifying expenditure on plant and machinery may benefit from the annual investment allowance (AIA) which allows a 100% deduction for the expenditure in the year in which it is incurred up to the £1 million AIA limit. Where the AIA is not available, or the taxpayer does not wish to claim it, writing down allowances are given at the rate of 18% for main rate expenditure and at 6% for special rate expenditure. Companies can also benefit from full expensing on qualifying new plant and machinery that would otherwise be eligible for main rate writing down allowances. Like the AIA, this provides immediate relief for the full amount of the expenditure but, unlike the AIA, the amount of expenditure that can benefit from full expensing is not capped. A 50% first-year allowance is available to companies on new qualifying assets that would otherwise qualify for special rate writing down allowances, as long as the expenditure is incurred on or before 31 March 2026. This can be useful if the AIA has been used up. First-year allowances are available at a 100% rate for new zero emission cars. This again is beneficial as expenditure on cars does not qualify for the AIA, full expensing or the 50% first-year allowance available to companies.

Adjusting the profit

As a result of the differences between depreciation and capital allowances, it is necessary to make an adjustment to the accounting profit to arrive at the taxable profit. Depreciation must be added back to the accounting profit and capital allowances deducted (or balancing charges added) to arrive at the taxable profit. Further adjustments may be needed for other expenses that are not allowable for tax purposes, such as entertaining expenses.

Where the AIA or full expensing is claimed, relief is given in full for tax purposes earlier than for accounting purposes. This means that the taxable profit will be lower than the accounting profit in the year in which the expenditure is incurred, but in subsequent years the accounting profit will be lower as depreciation will continue to be charged but the capital allowances have already been given.


A Ltd is a new company and spends £200,000 on plant and machinery on which it claims the AIA.

For accounting purposes, depreciation is charged at 30% on a reducing balance basis.

The accounting profit for the year is £350,000 after charging depreciation of £60,000.

To arrive at the taxable profit, the depreciation of £60,000 must be added back, but the company can deduct the capital allowances of £200,000. The taxable profit is therefore £210,000.

Depreciable Asset vs. Capital Allowance: Key Differences

  • Depreciable Asset: A tangible item a business owns that loses value over time due to factors like use, wear and tear, or becoming outdated. Examples include equipment, vehicles, and buildings. Depreciable assets are recorded on the company's balance sheet.

  • Capital Allowance: A tax deduction in the UK that lets businesses offset the cost of buying qualifying assets against their taxable profits. Capital allowances offer a way to reduce tax liability and are calculated based on rates set by HMRC.

In Summary:

  • Depreciation is an accounting concept that spreads the cost of an asset over its useful life.
  • Capital allowances are a tax incentive to encourage businesses to invest in new assets.

Why This Matters: Accountants Chester

Understanding depreciation and capital allowances is crucial to ensure taxable profits are correctly calculated and available tax deductions are made us of.

Does depreciation reduce taxable income in the UK?

Yes, but not directly. Here's how it works:

  • Depreciation vs. Capital Allowances: Depreciation is an accounting concept that spreads the cost of an asset over its useful life. However, you can't deduct depreciation itself on your tax return. Instead, the UK tax system uses capital allowances.
  • How Capital Allowances Work: Capital allowances let you deduct a portion of the cost of qualifying assets (like machinery, equipment, certain buildings) from your business profits, reducing your taxable income.
  • Types of Capital Allowances: There are different types, including:
    • Annual Investment Allowance (AIA): Provides a 100% deduction for qualifying assets up to a certain annual limit.
    • Writing Down Allowances: Apply a percentage deduction to the asset's value each year.

Important: Not all assets qualify for capital allowances, and the rules can be complex. Consulting Accountants Chester will ensure you maximise these deductions correctly.

Depreciation Vs Capital Allowances Accountants Chester

No, capital allowances and tax-allowable depreciation are not the same, though they are similar concepts.

  • Depreciation is an accounting method to spread the cost of an asset over its useful life. It reflects the reduction in an asset's value due to wear and tear.

  • Capital allowances are a form of tax relief in the UK that allows businesses to deduct the cost of certain assets from their profits over time, reducing their tax bill.

Key Point: Capital allowances are the tax-deductible version of depreciation.

Let's illustrate with an example:

You buy a machine for £10,000 with a useful life of 5 years.

  • Depreciation: You might record £2,000 depreciation expense each year in your accounts.
  • Capital Allowances: The tax rules might allow you to claim more or less than £2,000 per year as a deduction, depending on the type of asset and current tax incentives.

If you're looking for Accountants Chester, it's crucial to find an accountant who understands the complexities of capital allowances to ensure you maximise your tax benefits.

What qualifies for capital allowances in the UK?

Capital allowances are a form of tax relief for businesses investing in qualifying assets. Here's a breakdown of what generally qualifies:

  • Plant and Machinery: Equipment essential for your business operations (computers, vehicles, manufacturing tools, etc.).
  • Structures and Buildings: Costs incurred in constructing, renovating, or converting commercial buildings.
  • Research and Development (R&D): Investments in scientific or technological advancements.
  • Mineral Extraction: Specific expenses related to mineral exploration and extraction.
  • Intellectual Property: Costs of acquiring patents and 'know-how' (industrial techniques).

Important Notes:

  • Annual Investment Allowance (AIA): Most businesses can fully deduct the cost of qualifying assets up to a certain annual limit.
  • Special Rates: Some assets, like energy-efficient equipment, may qualify for enhanced allowances.

Why is this relevant for businesses seeking Accountants Chester?

Why is depreciation not tax deductible in the UK?

While depreciation itself is not directly deductible for tax purposes in the UK, businesses can utilise a system called capital allowances to gain similar tax benefits. Here's the breakdown:

  • Depreciation: This is an accounting practice that spreads the cost of an asset (like machinery or a building) over its useful life, reflecting its decline in value.
  • Capital Allowances: Instead of deducting depreciation directly, UK businesses claim capital allowances. These allowances permit a deduction of a portion of an asset's cost from taxable profits each year.

Why the system works this way:

  • Spreading the cost: It aligns the tax benefit with the period when the asset generates income for the business.
  • Encouraging investment: Capital allowances offer an incentive for businesses to invest in new assets.

Important Note: The types of capital allowances and the rates at which they can be claimed depend on the specific asset. HMRC (Her Majesty's Revenue and Customs) provides detailed information on the rules and regulations.

Accountants Chester have in-depth knowledge of capital allowances to ensure you maximise your tax benefits.

While depreciation itself isn't directly deductible for UK tax purposes, you can claim relief through something called Capital Allowances. These tax deductions essentially account for the depreciation of qualifying assets over time.

Key Points:

  • Capital Allowances: Allow you to deduct a portion of the cost of qualifying assets (machinery, vehicles, certain buildings, etc.) from your taxable profits.
  • Annual Investment Allowance (AIA): Lets you deduct the full cost of most assets in the year of purchase, up to a specified annual limit.

It's highly recommended that you consult Accountants Chester or a tax advisor for specific guidance on how depreciation and capital allowances can impact your business's tax situation.

    • Electric cars
    • Gas refueling equipment
    • Zero-emission goods vehicles
    • Electric vehicle charging points
  • Super-Deduction: The Spring Budget, on 15th March 2023, confirmed the removal of the temporary super-deduction capital allowance, and replaced it with a new temporary allowance known as 'full expensing'.

  • Annual Investment Allowance (AIA): Provides 100% tax relief up to a certain annual threshold.

In the UK, depreciation itself isn't directly deductible for tax purposes. However, businesses can use a system called Capital Allowances to claim tax relief on the cost of qualifying assets over time. Here's how it works:

  • Capital Allowances: Instead of deducting depreciation as an expense, you can claim capital allowances to reduce your taxable profits. These allowances let you deduct a portion of the asset's cost each year it's in use.
  • Types of Assets: Capital allowances are available for assets like machinery, equipment, certain fixtures within business premises, and even some vehicles.
  • Rates and Rules: The rates at which you can claim capital allowances vary depending on the type of asset. There are also special rules like the Annual Investment Allowance (AIA) which lets you deduct the full cost of certain assets upfront.

Why this system? The system of capital allowances aims to provide a more accurate and consistent approach to recognising the cost of assets used in a business over their useful life.

There are a few reasons why an asset might not be depreciated:

  • Indefinite Useful Life: Some assets, like land, don't lose value from wear and tear or become obsolete over time. As their value doesn't decline with use, there's no need for depreciation.
  • Fully Depreciated: Assets are depreciated until they reach their residual or salvage value (the estimated value at the end of their useful life). Once that value is reached, depreciation is no longer applied.
  • Appreciating Assets: Some assets like fine art, antiques, or specific collectibles might increase in value over time. Depreciation wouldn't make sense in these cases.
  • Immateriality: If an asset's cost is very low and its impact on financial statements is negligible, accountants may choose not to depreciate it for the sake of simplicity.

Important Note: Depreciating assets appropriately is crucial for businesses to get an accurate picture of their financial health. If you're in the Chester area and have questions about asset depreciation in your specific situation, it's advisable to consult Accountants Chester.

Yes, depreciation does reduce capital, but it's important to understand the context:

  • Accounting: Depreciation is an accounting method used to spread out the cost of a tangible asset (like equipment or buildings) over its useful lifespan. It reduces the asset's value on the company's balance sheet, which decreases overall equity (capital).
  • Taxation: Depreciation expenses are tax-deductible. This reduces taxable income, potentially leading to tax savings, which preserves some cash flow (a component of capital).
  • Cash Flow: Depreciation itself is a non-cash expense. It doesn't directly reduce day-to-day cash, but it does impact the profitability reflected on financial statements, which can slightly influence a company's ability to secure financing.

Key Points for Businesses in Chester:

  • Accuracy: Using proper depreciation methods ensures your financial statements accurately reflect asset values and expenses.
  • Tax Benefits: Understanding capital allowances and depreciation rules is crucial for maximising tax deductions.
  • Decision-Making: Analysing the impact of depreciation on your business's overall financial health can aid in investment and long-term planning decisions.
