Differentiating personal and company expenses ensures the correct tax treatment, saving time and avoiding potential penalties. This comprehensive A-Z guide breaks down common business expenses, their tax implications, and provides HMRC references to support your claims. Clear record-keeping is key to staying organised and compliant.

A: Accountant & Advertising

Accountant

Claim tax relief for accountancy fees incurred for business purposes, such as preparing annual accounts, tax computations, and financial statements. Be cautious if personal tax returns are included—this would be a taxable benefit unless recorded as a deduction from the director’s loan account. Always request invoices that clearly separate personal and business fees.

Advertising & Marketing

Advertising expenses wholly and exclusively for business purposes qualify for tax relief. This includes costs like social media ads, print campaigns, and digital marketing. However, certain activities, like client entertainment disguised as promotion, won’t qualify. Ensure expenses are clearly categorized.

B: Bank Charges & Broadband

Bank Charges

Business bank account charges, such as interest and transaction fees, are tax-deductible. Charges incurred on personal accounts used for business purposes do not qualify, so it's crucial to separate personal and business banking.
HMRC Guidance

Broadband

  • Home Broadband: If used for both personal and business purposes, claim only the business-use percentage. Keep documented evidence to justify the split.

  • Office Broadband: If the contract is in the company’s name and used solely for business, the entire cost can be claimed.

C: Charitable Donations & Computer Equipment

Charitable Donations

Limited companies can claim tax relief on donations made under Gift Aid, provided they meet HMRC’s requirements. Always maintain records for compliance.

Computer Equipment

If used solely for business purposes, computer equipment qualifies for capital allowances. Partial personal use may lead to a taxable benefit, so maintain clear logs of usage.

D: Dogs (Working Animals)

Expenses for working animals, like guard dogs, may qualify for tax relief if the business can justify their necessity. Keep evidence of the animal’s role in business operations.

E: Electricity & Entertaining

Electricity

  • Home Office: A percentage of home electricity bills can be claimed based on business use. Simplified HMRC rates may also apply.

  • Business Premises: Entire costs of electricity, heating, and lighting for business premises are allowable.

Entertaining

  • Clients: Entertainment costs for clients, such as meals or events, are not tax-deductible.

  • Employees: Costs for employee events, like annual Christmas parties, are deductible if they meet HMRC’s criteria (e.g., available to all staff and within £150 per head).

F: Flights & Food

Flights

Business-related flights are tax-deductible. If the trip includes personal activities, apportion the expenses accordingly. Keep itineraries and receipts as evidence.

Food & Drink

  • While Travelling: Meals purchased during business travel are allowable. Retain receipts and travel details to support claims.

G: Gifts

To Employees

Small gifts under £50 (e.g., as trivial benefits) can be tax-free, provided they are not cash or vouchers.

To Clients

Gifts must be below £50 and carry company branding to qualify for tax relief. Items exceeding this threshold or without branding may not be eligible.

H: Hotel Accommodation

Hotel stays for business trips are allowable. If combined with personal travel, claim only the business-related portion. Maintain receipts and records to avoid disputes.
