A Concise Sole Trader Tax Guide


Embarking on the journey of self-employment signifies a pursuit of autonomy, embracing the freedom that accompanies being the master of your professional destiny. However, with this newfound independence, the onus of managing business administration, formerly handled by superiors, falls squarely on your shoulders. Among these responsibilities, navigating the intricacies of business taxes now rests with you.

The tax obligations for a sole trader, known for its simplicity in business structure, hinge upon specific regulations that necessitate a comprehensive understanding. Despite its straightforward nature, adhering to various rules becomes imperative to stay abreast of your tax commitments. This article aims to provide a succinct overview of the diverse taxes applicable to sole traders, shedding light on payment timelines and elucidating the process to ensure timely and accurate submission of taxes.

Advantages and disadvantages of being a sole trader

The allure of being a sole trader comes with distinct advantages, with freedom standing out as a primary benefit. The autonomy to dictate working hours and choose projects cultivates a work environment tailored to personal preferences. Moreover, the appeal lies in absolute control over finances, as payments are directed straight to the individual. This financial autonomy allows for versatile use of profits, whether for skill development or well-deserved leisure, and the added perk of claiming tax relief on various business-related expenses, such as travel.

However, this independence carries its own price tag in the form of increased responsibility. As a sole trader, the obligation to declare income to HMRC via a Self Assessment tax return becomes a pivotal task. While the prospect may lack excitement, it is an essential aspect of maintaining compliance. This declaration, encompassing earned income and claimed expenses, serves as the basis for HMRC to assess and tax the generated profits. Unlike a conventional setup where tax deductions occur automatically, the onus now lies on the individual to settle the resulting tax bill directly with HMRC.

Failure to adhere to the deadlines for submitting the tax return or settling the tax bill promptly can incur penalties and interest charges, underscoring the importance of meticulous preparation in navigating the responsibilities associated with being a sole trader.

As a sole trader, how do I pay tax?

For individuals transitioning from employment to sole trading, the tax payment process undergoes a fundamental shift. In a conventional employment scenario, taxes are seamlessly managed through PAYE (Pay As You Earn), where the employer deducts the requisite taxes from monthly earnings and remits them to HMRC on the employee’s behalf, leaving the net amount as take-home pay.

Contrarily, sole traders navigate a distinct taxation path. Obligated to submit a Self Assessment tax return annually, the deadline for this submission falls on the 31st of January each year. This comprehensive declaration encompasses crucial financial details, including gross earnings, taxable profits, and business-related expenses incurred throughout the year. The insights derived from the Self Assessment serve as the foundation for determining the taxes owed to HMRC, with the payment deadline set for the subsequent 31st of January. This procedural shift underscores the self-reliance and proactive engagement required of sole traders in managing their tax affairs.

How to register for Self-assessment?

Embarking on your solo professional journey doesn’t necessitate immediate registration for Self Assessment, providing a grace period for acclimatization. However, registration becomes imperative if you fall into any of the following categories:

  1. Earning more than £1000 from self-employment in a tax year.
  2. Needing proof of self-employment, such as for claiming tax-free childcare.
  3. Seeking to make voluntary Class 2 National Insurance contributions to bolster eligibility for state benefits.

Should you meet any of these criteria, ensure timely registration for Self Assessment, preferably no later than the 5th of October following the conclusion of the tax year in question. Upon setting up your Government Gateway account, anticipate receiving correspondence from HMRC containing your Unique Taxpayer Reference (UTR) and an activation code within a two-week timeframe. This information enables the activation of your online account.

Subsequently, you can proceed to furnish your details and complete your Self-assessment tax return (referred to as SA100). Alternatively, if the paperwork seems daunting, there’s the option to enlist assistance for filing from a reliable service provider.

As a sole trader, what taxes must I need to pay?

For sole traders, the tax obligations primarily revolve around Class 2 and Class 4 National Insurance contributions (NICs) and Income Tax payable to HMRC. Typically, the majority will only be liable for these payments, with Value Added Tax (VAT) coming into play for those earning above £85,000 annually or those who voluntarily opt-in.

Following the submission of your Self Assessment tax return, HMRC will issue your Self Assessment tax bill, consolidating your National Insurance contributions and Income Tax. Payment deadlines are crucial, with the 31st of January marking the due date for settling any outstanding tax from the preceding tax year, termed as a balancing payment, along with the initial instalment of your payment on account. Subsequently, the 31st of July becomes the deadline for remitting the second and final instalment of your payment on account. Awareness and adherence to these timelines are essential for sole traders to fulfil their tax responsibilities promptly and avoid potential penalties.

An introduction to Income Tax

Income Tax, applicable to the income derived from self-employment, is calculated by subtracting accrued business expenses from the total profit, constituting the taxable profit. Mathematically expressed as:

Taxable profit = Total profit – Business Expenses

Unlike scenarios where taxes are deducted at source, as in the case of a monthly salary, individuals in self-employment, unless part of the Construction Industry Scheme (CIS), bear the responsibility of ensuring adequate funds are set aside for the impending Self Assessment submission.

Maintaining meticulous records of expenditure is paramount to the accuracy of your tax bill during Self Assessment. This practice not only minimizes the risk of overpaying taxes but also opens avenues for claiming specific tax reliefs designed for small businesses. Notable among these are allowable expenses and capital allowances.

To pre-emptively gauge your tax liability and avoid last-minute complications, gaining a comprehensive understanding of tax bands is essential. This proactive approach ensures better financial planning and readiness when the Self Assessment deadline looms, contributing to a smoother and more efficient tax submission process.

Introduction to Tax Bands (Tax Rates)

For individuals earning less than £100,000 annually, a Personal Allowance of £12,570 is typically granted, exempting the initial £12,000 of income from Income Tax obligations. Beyond this threshold, the applicable tax bands, contingent on your income, are outlined as follows:

  • Personal Allowance: Up to £12,570, Tax Rate: 0%
  • Basic rate: £12,571 to £50,270, Tax Rate: 20%
  • Higher rate: £50,271 to £150,000, Tax Rate: 40%
  • Additional rate: Over £150,000, Tax Rate: 45%

It’s noteworthy that these bands can be influenced by factors such as pension contributions and donations, as elaborated in our article ‘Tax saving tips for sole traders.’ Additionally, other tax-free allowances can be factored in, with the guidance of an Ember accountant facilitating a tailored assessment based on individual circumstances. This strategic approach enables a more nuanced understanding of the tax landscape and empowers individuals to optimize their tax positions effectively.

Introduction to National Insurance

The impact of your earnings extends beyond Income Tax, with your profits also influencing the amount payable in National Insurance contributions.

Class 2 National Insurance is contingent on the Small Profits Threshold, where surpassing this threshold incurs a weekly National Insurance rate. For the tax year 2022/23, this threshold stands at £6,725, accompanied by a weekly rate of £3.15, resulting in a total tax of £163.80.

If your profit remains below £9,881, Class 4 National Insurance is not applicable. However, earnings exceeding this threshold incur taxation on a percentage basis. Individuals earning between £9,568 and £50,270 are taxed at 10.25% of their profits in the tax year 2022/2023. Those surpassing £50,270 face a 3.25% charge.

It is noteworthy that Class 2 and Class 4 National Insurance contributions remain unaffected by other taxable income, ensuring accuracy in the figures obtained from your Personal Tax report. This distinction underscores the importance of a precise understanding of National Insurance implications to facilitate comprehensive financial planning.

Government introducing Making Tax Digital (MTD)

To enhance the ease of financial transactions for small business owners, the government introduced Making Tax Digital (MTD), commencing with MTD for VAT in April 2019. Initially, solely VAT-registered business proprietors exceeding the £85,000 VAT registration threshold were mandated to enroll in MTD for VAT. However, since April 2022, this requirement extended to all VAT-registered business owners, irrespective of their overall taxable turnover.

The inception of MTD aims to streamline the tax submission process for business owners, mitigating the risk of penalties for missed deadlines and underpaid taxes. Utilising MTD-approved software, such as Ember, proves instrumental in maintaining well-organized digital records, simplifying record-keeping and facilitating efficient reviews.

The government’s commitment to MTD transcends VAT, with plans in place for the implementation of MTD for Income Tax Self Assessment (ITSA) and Corporation Tax (CT) in 2024 and 2026, respectively. To prepare your business for these impending changes, refer to our comprehensive guide on navigating the transition to MTD. Stay informed and proactive to ensure a seamless adaptation to the evolving landscape of tax compliance.


Navigating the complexities of sole trader tax can be challenging, but grasping the essentials is pivotal for maintaining a positive cash flow and steering clear of future fines. To summarise:

  • If your self-employment earnings exceed £1,000 in a tax year, self-assessment registration is necessary.
  • Your Self-assessment tax bill encompasses Income Tax for the current tax year, along with Class 2 and Class 4 National Insurance contributions.
  • The total owed in Income Tax and Class 4 National Insurance is influenced by your taxable profit, while Class 2 National Insurance is set at a fixed rate by HMRC.
  • The deadline for submitting your Self Assessment is the 31st of January.
  • This date also marks the deadline for the first instalment of your payments on account, covering half of your tax bill for the subsequent tax year. The second instalment is due on the 31st of July.
  • If your earnings surpass £85,000 in a tax year, VAT registration becomes mandatory.
