A receipt in your wallet may look like a minor detail, but it can affect your tax bill, your VAT position and the reliability of your management information. Knowing how to claim business expenses means more than saving receipts until year-end. It means recording costs properly, separating personal spending and using the information to see what your business is really costing to run.
For business owners in Manchester and beyond, the central rule is straightforward: an expense must be incurred wholly and exclusively for the purposes of the trade. Applying that rule in real life can be less straightforward, particularly when a cost has both business and personal use.
How to claim business expenses under HMRC rules
The starting point is whether the cost has a genuine business purpose. If you buy materials to complete a client project, pay for bookkeeping software or travel to a customer meeting, the connection is usually clear. If an expense is partly personal, you can normally claim only the identifiable business element.
This is why context matters. A mobile phone used for customer calls and personal use is not automatically disallowed, but the personal proportion needs to be excluded. The same principle applies to broadband, vehicle costs and use of a room at home. A sensible calculation, supported by a consistent method, is far more useful than trying to claim the full amount without evidence.
The rule also applies to the reason for the expense, not simply where a receipt came from. Buying a smart jacket because you want to look professional at meetings is usually not an allowable clothing expense, as it can be worn privately. Protective clothing, a branded uniform or specialist safety equipment may be different.
For a limited company, an expense paid personally by a director can still be reimbursed by the company where it is a legitimate company cost. Keep the receipt and record the payment through the director’s loan account or expense system. For sole traders and partnerships, business costs paid from a personal account should also be recorded, but they are normally treated through the owner’s capital account rather than as a reimbursement.
Keep evidence while the transaction is fresh
Good records are the foundation of a successful expense claim. HMRC can ask to see evidence supporting figures on a tax return, and records also help you avoid missing valid deductions. Waiting until the accounts deadline usually creates unnecessary work and makes it harder to remember why a payment was made.
A receipt, invoice, bank statement or digital record should show what was bought, when, from whom and how much was paid. For travel and subsistence, add a short note explaining the business journey or meeting. A card payment alone proves that money left the account, but it may not prove the business purpose of the item.
Digital bookkeeping software can make this much easier. Photograph receipts as you receive them, attach them to the transaction and use clear categories. Regular bookkeeping gives you a current view of overheads, rather than a box of paperwork and a surprise tax calculation after the year has ended.
Where records are lost, do not invent a figure. Ask the supplier for a duplicate invoice, check your online account or retain other evidence of the purchase. The stronger and more contemporaneous your records, the easier it is to support the claim.
Common allowable business expenses
The expenses available depend on how your business operates, but many small businesses incur similar day-to-day costs. These often include premises costs, insurance, professional fees, advertising, website hosting, software subscriptions, telephone charges, staff costs, business bank charges and training that maintains or updates skills used in the existing trade.
Travel costs may be allowable when the journey is wholly for business. This can include rail fares, parking, hotel accommodation and meals bought while travelling overnight for work. Ordinary travel between home and a permanent workplace is normally treated as private commuting, even if you work long hours or make calls on the way.
Business entertaining is a common source of confusion. Taking clients out for a meal may help build a relationship, but client entertaining is generally not deductible for corporation tax or income tax purposes. Staff entertaining can be treated differently, subject to the circumstances and relevant limits. Recording these costs separately stops them being accidentally included as tax-deductible expenditure.
If you are VAT registered, consider VAT at the point of recording the purchase. Input VAT is generally recoverable only where the expense relates to taxable business activities and you hold valid VAT evidence. Some expenses have special treatment, and blocked input tax can apply, so do not assume that every VAT amount on a receipt is reclaimable.
Mileage, vehicles and working from home
Vehicles and home working deserve particular care because business and private use often overlap.
For business mileage in a personally owned car, many sole traders and companies use HMRC’s approved mileage rates. This can be simpler than calculating the business share of fuel, repairs, insurance and other running costs. Keep a mileage log showing the date, destination, reason for the trip and miles travelled. If a company pays mileage to a director or employee within the approved rates, it is generally a straightforward way to reimburse business travel.
Alternatively, a sole trader may claim the business proportion of actual vehicle costs. The best route depends on your mileage, the type of vehicle and how much private use there is. Once a method is chosen, consistency matters.
For working from home, you may be able to claim a reasonable share of household costs, such as heating, electricity, internet and council tax, where appropriate. A simplified flat-rate method may suit some self-employed people, while a proportion based on rooms and business use may be more accurate for others. Company directors should take advice before charging rent to their company, as it can create tax consequences personally and for the company.
Know the difference between a running cost and an asset
Not every business purchase is deducted in the same way. Day-to-day running costs, often called revenue expenditure, are usually deducted from profits in the period they relate to. Larger items that provide an enduring benefit to the business, such as machinery, equipment or computers, are generally capital expenditure.
Capital items may still attract tax relief, often through capital allowances, but they are not simply treated like stationery or a monthly software subscription. The timing and amount of relief can depend on the asset, the business structure and available allowances. If an item has private use, that can affect the claim too.
This distinction matters when budgeting. A significant purchase can be worthwhile for growth, but the accounting treatment, cash impact and tax relief may not all happen in the same way or at the same time.
Avoid the errors that create problems later
Most expense issues come from ordinary habits rather than deliberate mistakes: using one bank card for everything, failing to retain receipts, claiming the full cost of mixed-use items or posting personal purchases to business expenses. A separate business bank account is not only tidier; it gives you clearer financial information for decisions about pricing, cashflow and profitability.
It is also wise to agree an expenses policy if you have staff or several directors. Set out what can be claimed, what evidence is needed, who approves payments and how quickly claims should be submitted. This protects the business and gives everyone the same practical rules to follow.
Review expense categories at least monthly. Unexpected rises in subscriptions, vehicle costs or supplier charges can reveal a margin problem before it becomes a cashflow issue. Proper bookkeeping is therefore not just a compliance exercise – it is a useful management tool.
Make expense claims part of better planning
The best approach is to build expense recording into the way you run the business. Capture evidence promptly, describe the business purpose, separate personal costs and ask for advice before making an unusual or high-value claim. This reduces year-end stress and gives you accounts that can support better decisions throughout the year.
RK & Co helps business owners turn accounting records into practical and simple advice, from day-to-day bookkeeping to tax planning and cashflow forecasting. A short conversation before a cost is incurred can sometimes prevent an expensive misunderstanding later.
Well-managed expenses do more than reduce taxable profit. They show where your money is going, give you confidence in your figures and leave you better placed to invest in the next stage of your business.
