Allowable Business Expenses You Shouldn’t Ignore

HMRC allows sole traders to claim back a wide range of everyday business costs. The key is understanding what qualifies—and keeping good records to back it up. Here are some of the top deductions you should be tracking:

1. Business Use of Home

If you work from home, you can claim a portion of your rent, household costs — including electricity, internet, rent, council tax, and mortgage interest — based on the area used for business. HMRC offers simplified or actual cost methods.

2. Office and Workspace Costs

Whether you rent a studio, use a shared co-working space, or work from home, you can claim back part of your rent, utility bills, and internet as business expenses. HMRC provides simplified flat rates for home use, or you can calculate actual usage.

3. Travel and Vehicle Expenses

If you use your personal vehicle for business—whether to meet clients, deliver goods, or run errands—you can deduct mileage or actual expenses (fuel, insurance, maintenance). Public transport and parking fees also count when they’re business-related.

4. Equipment, Tools & Software

Anything essential for your business — such as laptops, cameras, tools, or industry-specific software — is eligible for full or partial deductions. You may need to claim these as capital allowances if they’re expected to last multiple years.

5. Professional Fees and Training

Expenses like accountant fees, solicitor, designer, business-related courses, certifications, and trade association memberships are fully deductible. Even subscriptions to trade publications or online tools like Canva or Adobe Suite can count. Keeping your skills sharp? That’s tax deductible too — if the training relates to your current work.

6. Marketing and Promotion

From social media ads and printing flyers to building a website or hiring a branding expert — if it's promoting your business, it's claimable. Just keep receipts and evidence of the business purpose.

7. Training and Development

Courses, workshops, seminars—even some coaching—can be claimed if they improve your skills for your existing business. Upskilling is an investment, and HMRC recognises that.

You don’t need to be a tax expert to stay on top of your deductions — you just need clarity and a little support. By understanding what you can claim, you’ll be better equipped to make smart decisions, save money, and grow with confidence.

Sole Trader Tax Questions — Answered

What expenses can I claim as a sole trader in the UK?

You can claim business-related expenses like home office costs, travel, equipment, marketing, training, and professional fees. The key is that the cost must be incurred “wholly and exclusively” for business use.

Can I claim part of my home bills if I work from home?

Yes — HMRC allows sole traders to claim a proportion of home expenses like rent, electricity, internet, and council tax. You can use a simplified flat rate or calculate based on actual usage.

What’s the difference between capital allowances and expenses?

Day-to-day business costs are claimed as expenses, but long-term items like laptops or tools may qualify as capital allowances. This lets you deduct their value over time instead of all at once.

Do I need receipts for all deductions?

Absolutely. HMRC expects accurate records — digital or paper — for everything you claim. Without receipts or clear documentation, deductions may be disallowed if investigated.
