Equipment and Tools: Claiming Correctly as a Sole Trader

Revenue Expense or Capital Allowance?

When you buy equipment or tools for your business, the tax treatment depends on the nature and value of what you're purchasing. Understanding the difference between revenue expenses and capital expenditure is crucial for claiming correctly.

Revenue expenses are day-to-day running costs — items that are consumed relatively quickly or have a short useful life. These are deducted directly from your profits.

Capital expenditure is spending on assets that provide value over a longer period. These are claimed through capital allowances, which spread the deduction over time (or allow you to claim in full using the Annual Investment Allowance).

The Annual Investment Allowance (AIA)

The Annual Investment Allowance is the most generous capital allowance for sole traders. It allows you to deduct the full cost of qualifying plant and machinery in the year you buy it, up to £1,000,000 per year.

For most sole traders, this means you can effectively claim 100% of your equipment purchases in the year you make them — the £1 million limit is far more than most individuals would spend.

What qualifies for AIA:

• Computers, laptops, tablets, and monitors
• Printers, scanners, and office equipment
• Power tools and hand tools
• Machinery
• Office furniture (desks, chairs, shelving)
• Vans and commercial vehicles (but not cars)
• Kitchen and catering equipment
• Specialist trade equipment

What doesn't qualify:

• Cars (these go into capital allowance pools with different rates)
• Items used for entertainment purposes
• Buildings and land (though integral features may qualify)

Small Items: Just Claim Them

In practice, many small equipment purchases can simply be claimed as revenue expenses without worrying about capital allowances. HMRC doesn't set a strict threshold, but items under roughly £500 with a relatively short useful life are commonly treated as revenue expenses.

Examples typically claimed as revenue expenses:

• Hand tools (hammers, screwdrivers, spanners)
• Small power tools (electric drill, sander)
• Keyboard, mouse, webcam
• Phone headset
• Storage boxes and organisers
• Replacement parts and consumables

Examples typically claimed as capital allowances:

• Laptop or desktop computer (£500+)
• Professional camera equipment
• Industrial machinery
• Commercial kitchen appliances
• Workshop benches and large equipment

The distinction isn't black and white. If you're unsure, using the AIA for any business asset purchase is safe — it gives you 100% relief in year one regardless.

Mixed-Use Equipment

If you use equipment for both business and personal purposes, you can only claim the business proportion. A laptop used 70% for business and 30% for personal use qualifies for 70% of its cost.

For capital allowances, you apply the business proportion when calculating your claim. For a £1,000 laptop used 70% for business:

• AIA claim: 70% x £1,000 = £700

Keep a note of how you determined the business proportion. For computers and similar equipment, a time-based estimate (hours of business use vs total use) is usually the most practical approach.

Specific Categories

Computers and Technology

Laptops, desktops, tablets, monitors, printers, and networking equipment are all qualifying plant and machinery. Claim through AIA for items over £500 or as a revenue expense for smaller items.

Don't forget peripherals: docking stations, external drives, cables, and adapters are all business expenses.

Trade Tools

If you're a tradesperson, your tools are essential business assets:

• Hand tools (revenue expense — they wear out)
• Power tools (AIA or revenue, depending on cost)
• Specialist instruments (AIA for higher-value items)
• Tool bags and storage (revenue expense)
• Replacement blades, bits, and consumables (revenue expense)

Office Furniture

Desks, chairs, bookcases, and filing cabinets qualify for AIA. A good ergonomic office chair costing £400+ is a capital item worth claiming.

Photography and Creative Equipment

Cameras, lenses, lighting rigs, microphones, and editing hardware are capital items for creative professionals. The full cost can be claimed through AIA in year one.

Kitchen and Catering Equipment

If you're in the food industry, ovens, refrigerators, food processors, and display units all qualify for AIA.

What About Replacing Equipment?

When you replace a piece of equipment, the replacement cost is treated in the same way as the original purchase — either as a revenue expense (if small) or through AIA (if larger).

If the old equipment has remaining value in a capital allowances pool, you'll have a balancing adjustment when you dispose of it. If you sell the old equipment, the proceeds reduce your capital allowances pool. If you scrap it with no proceeds, you can claim the remaining balance.

Record-Keeping

For equipment purchases, keep:

• Receipts showing the date, item description, and cost
• A note of the business use percentage for mixed-use items
• Records of any disposals (sales or scrapping)
• Your capital allowances calculations (your accounting software should handle this)

With Accounted, snap a photo of your equipment receipt and send it to Penny. She'll identify whether it should be treated as a revenue expense or capital item and record it accordingly.

Common Mistakes

Not claiming equipment at all. Some sole traders forget to claim tools and equipment because they buy them from general retailers rather than specialist suppliers.

Claiming cars through AIA. Cars don't qualify for AIA — they have their own capital allowance rules based on CO2 emissions.

Forgetting the business proportion. If equipment is mixed-use, only claim the business percentage.

Not keeping receipts. A bank statement shows you spent money, but a receipt proves what you bought. HMRC expects both.

Claim every tool and piece of equipment you buy for your business. Sign up to Accounted and let Penny keep your records straight.
