Accounting for self-employed tradespeople: what to track before tax season

When you are working as a self-employed tradesperson, your day is usually full before it even starts. You may be quoting for jobs, buying materials, driving between sites, dealing with customers, chasing payments and trying to keep your diary full. Accounting can easily become the job you leave until later.

The problem is that “later” often turns into tax season, and by then you may be trying to piece together receipts, bank payments, supplier invoices and mileage from months ago. That is stressful, and it can also mean you miss allowable expenses or make mistakes on your Self Assessment tax return.

Good record keeping does not have to be complicated. You just need to know what to track, where to keep it, and how often to update it. With the right habits, and the right accountant for sole trader support, your accounts can become far easier to manage.

Start with your job income

Your income is the first thing to track properly. This includes every payment you receive from customers, contractors, landlords, letting agents or commercial clients.

For each job, keep a clear record of:

• Customer name
• Job address
• Invoice number
• Date the work was completed
• Amount charged
• Amount paid
• Payment date
• Payment method

If you take deposits, stage payments or cash payments, record those too. Do not rely on memory. Even a small missed payment can affect your final profit calculation.

It also helps to separate personal and business banking. A dedicated business bank account makes it much easier to see what has come in and gone out. If everything is mixed with food shopping, family bills and personal transfers, tax season becomes much harder than it needs to be.

A good self-employed accountant can help you set this up in a simple way, so your records are clear from the start.

Keep every materials and supplier receipt

For tradespeople, materials can be one of the biggest costs. Whether you are a plumber, electrician, builder, decorator, carpenter, roofer or landscaper, you are probably buying items regularly.

This could include:

• Timber, plasterboard, cement or bricks
• Paint, sealants, screws and fittings
• Electrical parts and cables
• Plumbing supplies
• Tiles, flooring and adhesives
• Hire equipment
• Cleaning materials used after jobs

Keep the receipt or invoice for every purchase. If you buy materials for a specific job, note which job they relate to. This can help you understand whether that job was actually profitable once all costs are included.

You should also avoid paying for business materials in cash without keeping proof. HMRC may ask to see evidence if they ever check your records. A bank statement alone is not always enough if it does not clearly show what was bought.

Using proper sole trader accountancy services can help you organise these costs correctly, instead of guessing at the end of the year.

Track tools, equipment and protective clothing

Tools and equipment are part of running your trade business. Some items may be small day-to-day costs, while larger purchases may need to be treated differently in your accounts.

You should track spending on:

• Hand tools
• Power tools
• Ladders and access equipment
• Safety boots, helmets, gloves and protective workwear
• Tool repairs
• Replacement batteries and chargers
• Work phones or tablets
• Specialist trade equipment

If an item is used partly for business and partly for personal use, make a sensible record of the business use. This is where many self-employed people get stuck. You may know the item is needed for work, but your records should still support the claim.

This is also where sole trader accounting support can be useful. Instead of trying to work out every rule on your own, you can get clear advice on what can be claimed and how to record it properly.

Do not forget van, fuel and travel costs

Your van is often one of the most important parts of your trade business. It gets you to jobs, carries your tools, transports materials and helps you serve customers across different areas.

You should keep records for:

• Fuel
• Insurance
• Repairs and servicing
• MOT
• Road tax
• Parking
• Vehicle lease or finance payments
• Breakdown cover
• Business mileage
• Congestion, toll or clean air zone charges where relevant

If the vehicle is used for both business and personal journeys, keep a mileage log or a clear method for working out the business-use percentage.

It is also worth tracking travel by job. For example, if you regularly travel from Slough to Reading or surrounding areas, those costs can add up across the year. Good records help you price future jobs more accurately because you can see the real cost of travel, not just the time spent on site.

Keep CIS statements if you work in construction

If you work as a subcontractor under the Construction Industry Scheme, your contractor may deduct money from your payments and pass it to HMRC. These deductions are not something you should ignore. They count towards your tax and National Insurance position.

Keep every CIS statement you receive. Check that the figures match what was actually paid into your bank account. You should record:

• Gross amount before deduction
• CIS deduction
• Net amount received
• Contractor name
• Date paid
• Job or project reference

Missing CIS statements can delay your tax return and make it harder to reclaim any overpaid tax. If you often work for main contractors, keep your CIS paperwork in one folder throughout the year.

Accountants for self-employed individuals can help make sure CIS deductions are recorded correctly and included properly in your Self Assessment.

Watch your VAT position

Not every self-employed tradesperson needs to be VAT registered. However, you should still keep an eye on your turnover. The UK VAT registration threshold is currently £90,000 taxable turnover over a rolling 12-month period.

This means you should not only check your income at the end of the tax year. You need to monitor it throughout the year. If your work grows quickly or you take on several larger jobs, you could reach the threshold sooner than expected.

If you are already VAT registered, you need clear records of sales VAT, purchase VAT, VAT invoices and business expenses. A VAT return accountant can help you stay on top of submissions and avoid last-minute VAT stress.

Track wages if you take on help

Many tradespeople start alone, then bring in help as work grows. This may be casual labour, subcontractors, apprentices or employees. The accounting treatment can differ, so it is important to record things properly.

If you employ staff, you may need payroll, payslips, PAYE records, pension contributions and real-time submissions to HMRC. If you use subcontractors, you may need to consider CIS rules depending on the type of work and arrangement.

Keeping informal notes or paying people without proper records can create problems later. If you are growing your team, payroll accountant services in Slough can help you pay people correctly and stay compliant.

Use software before the year gets messy

You do not need complicated systems, but spreadsheets and paper receipts can become difficult once you are busy. Accounting software can help you connect your bank, categorise payments, store receipts and keep a clearer view of your profit.

Working with a certified QuickBooks accountant can make this easier because your software can be set up properly from day one. You can then track income, expenses, VAT and reports without having to rebuild everything at tax season.

This is becoming even more important with Making Tax Digital for Income Tax. If your qualifying income is above the relevant threshold, you may need digital records and regular updates to HMRC. Getting organised early is much easier than rushing later.

Prepare for your tax return before January

The Self Assessment deadline may feel far away, but January comes around quickly. If your records are tidy, your tax return is usually far less stressful.

Before tax season, make sure you have:

• All sales invoices
• Bank statements
• Receipts and supplier invoices
• CIS statements
• Mileage records
• Loan or finance agreements
• VAT records if registered
• Payroll records if you employ people
• Details of any personal income
• Pension contributions or other relevant tax information

A self-assessment tax return accountant can then prepare your return with fewer delays and fewer questions. More importantly, you can understand your tax bill earlier and plan your cash flow properly.

Make accounting part of your weekly routine

The best approach is not to wait until the end of the year. Set aside a short time each week to update your records. Upload receipts, check unpaid invoices, review your bank transactions and note down mileage while it is still fresh.

You do not need to become an accountant. You just need a system that keeps your business organised and gives your accountant the information they need.

With the right sole trader accounting services, you can spend less time worrying about tax and more time focusing on your trade, your customers and your next job.

FAQs

What records should self-employed tradespeople keep?

Do I need receipts for every business expense?

Yes, you should keep proof of your business expenses. You do not usually send receipts with your tax return, but HMRC can ask to see them if your return is checked. Digital copies are usually fine as long as they are clear and complete.

Can I claim tools and work clothing as a self-employed tradesperson?

You may be able to claim tools, equipment and protective workwear used for your business. The rules can depend on the item, how it is used and whether it is a day-to-day expense or a larger asset.

Should I use accounting software as a sole trader?

Accounting software can make life much easier, especially if you have regular jobs, lots of receipts, VAT records or CIS deductions. It can help you track profit, store receipts and prepare for tax season with less stress.

When should I speak to an accountant?

You should speak to an accountant as early as possible, not just when the tax deadline is close. Getting advice during the year can help you claim the right expenses, plan for tax, avoid errors and keep better records.
