1. Home Office Expenses
If you work from home, even part-time, you may be eligible to claim home office expenses. This includes a portion of your rent or mortgage interest, utilities, internet, and even cleaning costs. The key is to ensure the space is used exclusively for business.
What you can claim:
-
A proportion of heating, electricity, council tax, and rent
-
Broadband and phone services
-
Office furniture or equipment
Tip: Keep detailed records of the room’s usage and how you calculate the percentage of costs claimed.
2. Travel Expenses
Business-related travel can be fully deductible, whether you're meeting clients, attending a conference, or scouting new business opportunities.
Deductible travel costs include:
-
Train, bus, taxi, or plane fares
-
Accommodation for overnight stays
-
Meals (if part of overnight travel)
-
Mileage for business use of personal vehicles
Make sure the travel is strictly for business. Personal trips are not eligible.
3. Vehicle Expenses
If you use your vehicle for business purposes, you can claim expenses such as fuel, insurance, maintenance, and repairs. You can either use the actual cost method or the simplified mileage rate, depending on which provides a better deduction.
Examples:
-
Fuel and oil
-
Vehicle insurance
-
Servicing and repairs
-
Parking and tolls
Important: You can’t claim for regular commuting between home and work—it must be for business-specific journeys.
4. Office Supplies and Equipment
Anything you use to operate your business can typically be claimed. This includes pens, paper, printer ink, laptops, and desks. These are classified either as revenue expenses (for consumables) or capital allowances (for equipment expected to last more than a year).
Examples:
-
Stationery
-
Computers and accessories
-
Office furniture
-
Software subscriptions
Be sure to keep receipts and proof of purchase for every item.
5. Professional Services

This includes:
-
Legal advice

Tax preparation

Promoting your business is essential, and the cost of doing so is tax-deductible. This covers both traditional and digital advertising methods.
What you can deduct:
-
Website development and hosting
-
Social media advertising
-
Business cards and brochures
-
Email marketing software
Remember: only business promotion is deductible. Anything promoting a personal brand or unrelated venture isn’t.
7. Employee Salaries and Contractor Payments
Wages paid to employees, freelancers, or contractors are allowable deductions. You can also include employer National Insurance contributions, pensions, and benefits.
Deductible costs:
-
Salaries and wages
-
Employer’s National Insurance
-
Pension contributions
-
Bonuses and commissions
Ensure all payments are properly documented and legally compliant.
8. Training and Development
Investing in education that improves your skills or enhances your business can be tax-deductible. Courses must be directly related to your existing profession—not a completely new field.
Examples:
-
Online business courses
-
Industry certifications
-
Conferences and workshops
-
Training materials and books
Note: General education or unrelated degree programs are not deductible.
9. Insurance
Certain business-related insurance premiums are deductible. This includes public liability, professional indemnity, and business interruption insurance.
Examples:
-
Professional liability insurance
-
Equipment insurance
-
Cyber liability
-
Employer’s liability (if you have staff)
Insurance protects your business, so the tax system allows you to claim it back as an expense.
10. Bank Charges and Interest
Business bank account fees, credit card charges, and interest on business loans are all tax-deductible. If you use a personal account for business, only the business-related portion is allowed.
Deductible items:
-
Bank account maintenance fees
-
Overdraft charges
-
Interest on business loans or credit lines
-
Currency exchange fees for business transactions
Keep clear records of every financial transaction to back up your claims.
Bonus Tip: Use the Simplified Expenses Method (If Eligible)
HMRC offers a Simplified Expenses method for small businesses and sole traders, allowing you to use flat rates instead of complex calculations. This can apply to:
-
Business vehicle costs
-
Working from home
-
Living at your business premises
You can find more about this system on Wikipedia’s Self-Employment Tax entry for additional context.
