Understanding Allowable Expenses for Sole Traders

Allowable expenses for Sole Traders and Partnerships
Many sole traders do not know what they can and can't claim for in their business. So I thought I would list them in this blog.
It is important to understand that any expenses you want to claim for your business, must be wholly and exclusively for the business.
You cannot claim for anything you use personally. So, if you use e.g. a mobile phone both personally and for business, you can only claim the business proportion.
So lets make an easy list for you to follow!

Simplified expenses
Is a way of calculating some business expenses using flat rates, rather than working out the actual costs which can be more time consuming.
Simplified expenses are available for -
Motor expenses
Claim a flat rate per mile based on the type of vehicle.
Rates for 25-26 are -
45p per mile for cars and goods vehicles for the first 10000 miles, 25p above 10000 miles
24p for motorcycles
You cannot claim the actual costs for motor expenses, and simplified expenses. Once you choose how you want to manage expenses for your vehicle, you must stick with it until you change the vehicle.
You also cannot use Captial allowances ifyou are using flat rate expenses.
Use of home as office
You can claim a flat rate if you work from home at least 25 hours per month.
Rates for 25-26 are -
25-50 hours per month - £10pm
51-100 hours per month - £18pm
101 plus per month - £26pm
Flat rate covers a proportion of
- Utility bills
- Mortgage/rent
You can still claim a proportion of council tax, insurance, telephone and broadband on top.
Business premises used partly as a home
In the event of e.g. renting a room or owning a B&B, you can a flat rate per person for non-business expenditure, which is deducted off your total expenses. Again, mortgage interest, business rates and council tax are excluded from the flat rate so can be claimed separately.
Rates for 25-26 are -
1 person occupancy - £350pm
2 person occupancy - £500pm
3 or more - £650pm
Trading allowance
If your expenses are under £1000 for the year, you can instead claim the trading allowance.
This is a tax exemption of £1000.
Meaning, if your profit is £20000, and your expenses £500. you would make a profit of £19500.
You could claim £1000 trading allowance instead of listing all your expenses and reduce your profit to £19000.
It also means, if your income is £1000 or under, you do not have to fill in a tax return.
What is cash basis?
You record income and expenses when money actually changes hands, not when you invoice or are billed.
So:
You count income when you’re paid
You count expenses when you pay them
Understanding Capital Allowances
Capital allowances are a key area of allowable expenses that often causes confusion. They relate to the depreciation of capital assets like equipment or vehicles, allowing you to deduct a portion of the asset's cost over time, so are for higher cost items such as a £1000 computer or £20000 car.
You can claim Annual Investment allowance of up to £1m per year on vans, plant and machinery. Resulting in you being able to claim most if not all of your purchase. This still reduces your profit and therefore tax paid.
It’s essential to keep detailed records and receipts for these assets to ensure you claim the correct amount and speak to your accountant/bookkeeper when you make large purchases.
Tips for Accurate Record Keeping
Accurate record-keeping is essential for maximising your allowable expenses. Here are some tips to help you stay organised:
- Use dedicated business accounts for all transactions.
- Buy personal items from your personal accounts.
- Keep digital copies of all receipts and invoices.
- Regularly update your accounting records to prevent last-minute stress.
- Get help early if you feel overwhelmed.
