Be aware of the expenses you can claim from your company.

A business expense is a cost that is exclusively and wholly incurred for business purposes. An organisation needs to identify these as they allow you to claim tax relief on that amount.

The expenses that you claim from your company are deducted from the company’s profits, on which you will incur a corporation tax.

Therefore, it indicates that the higher the business-related expenses, the lower the profit, which leads to a lower corporation tax. You can find out more in our article How to reduce corporation tax in 7 steps.

Make contributions to pension funds.

Taxpayers in the UK have the opportunity to save their allowances up to £40,000 into a pension scheme of their choice.

If you are a contractor, self-employed or director and have income in your business that you are reluctant to withdraw due to increasing taxes, this is one of the highly beneficial methods that will be of great use.

Pension contributions are considered an allowable business expense and can be deducted from your company’s pre-tax profit. Pension tax relief is one of the single most effective methods of reducing your tax burden and is available to you at the highest tax rate.

If you have any unused pension allowance, ensure to reach your tax-free limit of £40,000 if you are a taxpayer and have sufficient funds to invest.

Make charitable donations.

Your company will be subject to tax relief on your corporation tax payments when you donate one or more of the following to a charity:

  • Trading stock or equipment
  • Money
  • Sponsorships
  • Shares, property, or land
  • Employees

Suppose you donate money, shares, property, or land. In that case, you can record them under ‘Qualifying Donations’ in your tax return and deduct them from your profit, which will effectively reduce the corporation tax payable.

If you decide on seconding your employees or sponsoring a charity, you can deduct them directly as an allowable business expense in your entity’s yearly accounts.

Utilise your ISA allowances.

ISAs help businesses to achieve gross interest or returns on savings. If you are in the higher income threshold bracket or close to the threshold, ISAs will not affect other allowances available to you, such as dividends and savings.

ISAs can be in the form of investments, cash, or both. These are very useful sources of income for the future, and an entity can achieve them tax-free.

Make use of the marriage allowance

Under the marriage allowance, you can transfer £1,260 out of your allowance to your husband, wife or civil companion.

This will bring down their tax by up to £252 annually (Considering the period between the 6th of April – the 5th of April).

Although this might not seem like a very significant saving, this can reduce your potential tax liability.

It is vital to pay attention to the fact that the lower earner should have an income level below the personal allowance to benefit as a couple. Therefore, under normal circumstances, this may not always be an option.

Claim your R&D tax relief

Suppose your business makes payments to introduce new products and invest in developing new processes and software. In that case, you are likely to have the chance of reducing your corporation tax by a significant amount.

You can also experience tax savings on research and development allowances, which you have spent on research equipment or facilities.

When companies invest in research and development activities, HMRC will be able to increase productivity, which is the main reason businesses are given this relief.

Make investments in plant and machinery

Businesses can claim immediate tax relief on specific assets up to a pre-defined limit, which is known as the “Annual Investment Allowance.”

This allowance facilitates a form of faster tax relief since the company can claim the total expenses in the year of purchase rather than claiming it over a more extended period which may be over several years.

Claim your business mileage expenses

If you utilise your personal car for trips concerning the business, you are allowed to claim expenses from the entity on a tax-free basis under the legally enforced rates per mile as follows:

  • 45p up to 10,000 miles
  • 25p for miles above 10,000

Claim the working from home allowance

This “Working from Home allowance” is available mainly to contractors who are forced to work from home. However, this claim is not allowed for those who choose to work from home.

From the 6th of April 2020, businesses were allowed to obtain £6 per week without any need for evidence of incurring extra costs. The benefit of this claim is that it is available irrespective of your method of contracting, Limited company, or third-party payroll company.
