Claiming the right expenses are a crucial part of running a business.

This is because claiming the right expenditure will result in tax relief claimed in the tax year.

Therefore reducing the income tax, corporation tax and national insurance paid by the taxpayers.

Why is claiming the right expenses important?

The consequence of not claiming expenses or tax relief within the time frame is paying too much tax.

Likewise, if the taxpayer claims disallowable expenses they face the risk of tax investigation in the nearest future.

This could lead to certainly paying unplanned tax, tax penalties with interest in the future.

Claiming the right expense

How to claim the right expenses?

There are three rules that could help to ensure certainly that the right expenses are claimed:

  1. Wholly and exclusively for business purpose:

For an expense to be tax-deductible, it has to wholly and exclusively for business purpose.

If the expense has an element of private use, it should be apportioned and only the business part should be deducted.

Therefore, when an expense cannot be safely apportioned because of the private element, it would be disallowed.



2.Revenue expense, not capital expenditure:

Revenue expense is one that does not have a lasting feature.

If the expense would need to be replaced within a year certainly it most likely would be revenue expenditure.

Likewise, expenses that relate to capital expenditure are also disallowed.

If it’s could last between 1-2 years, the business owner would need to access this themselves as it can be subjective based on the purpose.

However, if it could be used for more than 2years it most likely would not be a revenue expense.

Also, expenses that relate to capital expenditure are also disallowed. E.g. depreciation, amortisation or cost of acquiring fixed assets like buying a property.

  1. Expenses within the accounting period.

The accounting period is the time covered by the return you are trying to submit.

Therefore the expenses that you are trying to claim the relief for must be within the period of the return under assessment.


There are certain times when there is an exception to this rule.
