Expert accounting support built around sole traders

When you’re running a sole trader business or working as a freelancer, accounting should help you stay compliant, save time, and make better decisions, not create more admin.

Bookkeeping

Clear, organised records of your income and expenses so you always know where your business stands and your accounts stay ready for HMRC. Without accurate bookkeeping, it’s easy to lose track of costs, miss deductions, and create problems at tax return time.

Sole trader accounting

Year-end accounts prepared accurately by experienced accountants who understand the realities of running a sole trader business. If your figures are wrong or incomplete, you risk filing errors, missed reliefs, and avoidable back-and-forth later.

VAT returns

From VAT registration to quarterly submissions, we handle the process and make sure everything is filed correctly and on time. Missed VAT deadlines and incorrect returns can lead to penalties, interest, and unnecessary HMRC attention.

Self Assessment tax returns

Your Self Assessment return prepared, checked and submitted to HMRC so you stay compliant and avoid last-minute stress. Late filing penalties start at £100 and can escalate quickly, so we help make sure that doesn’t happen.

Payroll and pension submissions

As your business grows, your accountant helps you understand your numbers, identify tax efficiencies, and plan your next steps. Without clear advice, it’s harder to see what’s profitable, what to change, and when to take the next step.

Incorporation support

If your profits increase, we can guide you through switching from sole trader to limited company and help you choose the most efficient structure. Moving too late, or too early, can leave you paying more tax than necessary or using the wrong setup for your goals.

FAQs on sole trader accountant services

Do I need an accountant as a sole trader?

No, sole traders are not legally required to hire an accountant. However, many self-employed professionals choose to work with one to manage bookkeeping, prepare Self Assessment returns and ensure HMRC deadlines are met. An accountant can also help you claim allowable expenses correctly and reduce the risk of tax errors or penalties.

Can a sole trader do their own accounting?

Yes, a sole trader can manage their own accounts and submit their Self Assessment tax return directly to HMRC. That said, accounting involves maintaining accurate records, calculating taxable profit and keeping up with tax rules. Many sole traders prefer professional support to save time and ensure everything is filed correctly.

What records must a sole trader keep?

Sole traders must keep accurate records of income and business expenses. This usually includes invoices, receipts, bank statements, mileage logs and any documents relating to purchases or business costs. HMRC typically requires records to be kept for at least five years after the 31 January submission deadline for the relevant tax year.

How much can a sole trader earn before paying tax?

Sole traders only start paying Income Tax once their taxable income exceeds the Personal Allowance, which is currently £12,570 per year for most individuals. If your profit exceeds this threshold, you will pay Income Tax and National Insurance contributions based on the applicable UK tax bands.

What software is best for sole trader accounting?

Most sole traders use cloud accounting software to manage invoices, expenses and financial records. Tools such as Xero or other MTD-compatible platforms allow you to track income, organise receipts and prepare records for Self Assessment. Many accountants also provide integrated software as part of their accounting service.

Is hiring an accountant tax deductible for sole traders?

Yes. In most cases, accountant fees related to your business are considered an allowable expense. This means the cost of accounting services can usually be deducted from your business profits before calculating your tax liability.

How often should a sole trader meet with their accountant?

It depends on the complexity of your business. Some sole traders only speak with their accountant around Self Assessment deadlines, while others check in quarterly or monthly for bookkeeping reviews and tax planning. Regular communication helps ensure your records remain accurate and your tax position is monitored throughout the year.
