Expense categorisation for self-employed

Getting a grip on your expenses

So you run your own business, which is a great feat achieved, and along with that comes the unavoidable intricacy of dealing with your business’ taxes.

Being self-employed is stylish. Making your own schedule, setting business goals, having control over your income, these are all things that are slightly less attractive.

Filing your Self Assessment tax return might seem like a daunting task, but it can be made easier by keeping rigorous accounting records of your expenditures, as well as by breaking down those expenses into recognizable categories that will help you determine which HMRC will allow as a business expenditure and which it won’t.


What is a Self Assessment tax return?

Income tax is usually removed directly from your wages. But if you are self-employed, your wages aren’t provided in a linear fashion. You provide a product or service on your own basis, and you report whatever you earn off that to HMRC. This gets slightly more complicated when you add in any purchase of required materials to make your product or service. Expenses that your employer would normally cover if you worked for someone else, are now your responsibility. In the Self Assessment tax return, you will introduce all of the expenses that you pay to run your business and work out your taxable profit.


How is taxable profit determined?

How much of your profit can be taxed is determined through adding up the costs of running your business. Naturally, you’ll need to keep accurate records of your expenditures so that this calculation is more straightforward. In other words, allowable expenses are deducted from your gross profit to get your taxable profit.


What are allowable expenses?


How much a business owner spends in each category depends on the type and size of their business, but each category will be discussed with regards to how it pertains to your Self Assessment tax return.


So then, what are disallowable expenses?

Conversely to allowable expenses, disallowable expenses include any expenses not incurred wholly and exclusively for business purposes. Let’s break it down even further and examine what allowable and disallowable expenses are in each category.


What is Cost of Sales?

Cost of Sales is any expense incurred in obtaining or creating your product or service. This could include any stock purchased for your business, raw materials needed, any labour needed that is not your own, and other production costs. These are costs that pertain to buying items that you resell to your clients in the process of making your product or carrying out your service.


What counts as business expenses?

Any expenses that are incurred to produce the goods or services that your business provides can be classified as business expenses. An expense is only allowable for tax purposes if it's incurred ‘wholly and exclusively’ for the purposes of conducting your business.

The expenses your business incurs will depend on the industry your business operates in, the stage that your business is at and other factors that relate to the operation of your business.

Below you’ll find some practical and common approaches to making sense of your business expenses.

Fixed vs variable

Every business owner must keep track of their daily, monthly, and recurring business expenses. Some expenses will be fixed, and some will vary depending on how many sales your business is doing.



Capital expenditure vs operational expenses

There are two types of expenses that a business will incur: capital expenses (CapEx) and operational expenses (OpEx). Capital expenses are expenses that are incurred to purchase tangible or intangible assets. Capital expenses provide future economic benefits to the business and are normally kept in the business for more than one accounting period. Any expense that is capitalised will need to be depreciated over its useful economic life (how long you expect to use the asset for). Examples of capital expenses include the cost to buy machinery, computers, software, etc.
Operational expenses, on the other hand, are all regular expenses that are unlikely to have future benefits and these are expenses that your company has to make to maintain its daily operations. Examples of operational expenses include rent, employee salaries, travel expenses.

Capital Expenses vs Operating Expenses

    CapEx
  • Pupose: Assets purchased with a useful life beyond current year
  • When Paid: Lump sum up front
  • When Accounted For: Over 3-10 year lifespan while asset depreciates
  • Listed As: Property or equipment
  • Tax Treatment: Deducted over time as asset depreciates
    OpEx
  • Pupose: Ongoing costs to run a business
  • When Paid: Monthly or annual recurring
  • When Accounted For: In the current month or year
  • Listed As: Operating Cost
  • Tax Treatment: Deducted in the current tax year

There are, however, some greyer areas, so when in doubt ping our accountancy experts via the in-app chat if you have an account with us or right from the website if you don't. They will point you in the right direction.

Because this category carries more nuance than the other two, we’ve made a handy chart showing what falls in each category.

It can include furniture for your office, any expensive equipment used in your business, and computer equipment like printers, laptops, or tablets. This type of cost won’t be deducted fully, but rather you would recognize the cost over the useful life of the asset. You can claim capital allowances on the costs of purchasing and improving equipment such as:

The type of capital allowance and amount you can claim will depend on your assets and other circumstances. See this comprehensive guide on the gov.uk website for more information.


Simplified expenses if self-employed

If you’re not one to sit for hours working out the mathematical actual costs of using your vehicle for business, working from your home, or living in your business premises, then there is an option for you.
If you are a sole trader or in a business partnership that has no companies as a partner, you’re eligible to use simplified expenses. Simplified expenses are a way of calculating some of your business expenses using flat rates instead of working out your actual business costs.


Using simplified expenses

You first need to make sure you record business miles for vehicles, any hours you work at home, and how many people live at your business premises over the year. At the end of the tax year, you can use the flat rates for vehicles, working from home, and living at your business premises to work out your expenses. Then, you’ll need to include these amounts in the total for your expenses in your HMRC Self Assessment tax return.


How do I file my HRMC Self Assessment tax return?

You can file your tax return online or in paper form. If you’ve never sent in an online tax return, you’ll need to allow extra time as you need to register first and set up your tax return login. The next thing you’ll need is your records. Hopefully, you keep bank statements and receipts so that correctly filling in your online return is easier. Once you use your records to fill in your tax return online, HMRC will calculate what you owe based on what your report.
