If you’re a UK taxpayer, it’s likely you’ve heard of HMRC Self Assessment, but do you truly understand it? In this article, we break down the basics of UK HMRC Self Assessment and explore the concept of Payment on Account. Whether you are a seasoned pro or a newbie, this piece aims to demystify the complexities of self-assessment, helping you navigate the process with ease. So, let’s get started by shedding light on this fundamental aspect of UK tax obligations.
What is Self Assessment?
Definition of Self Assessment
Self Assessment is a system used by the UK tax authority, HM Revenue and Customs (HMRC), to collect income tax from individuals. It requires individuals to report their annual income, calculate their tax liability, and submit a tax return. Essentially, it is a way for you to report your income and determine your tax obligations to the UK government.
Who needs to do Self Assessment?
Self Assessment applies to individuals who meet certain criteria. If you fall into any of the following categories, you will likely need to complete a Self Assessment tax return:
- Self-employed individuals, including sole traders and partners in a business
- Company directors (unless they have been advised otherwise by HMRC)
- Those with an annual income of £100,000 or more
- Individuals with untaxed income, such as rental income from properties or dividends from investments
- People who receive income from abroad that is not taxed in the UK
- Trustees and personal representatives of deceased individuals
It is important to note that even if you are not eligible based on the criteria above, you may still need to complete a Self Assessment if HMRC requests it.
Purpose of Self Assessment
The main purpose of Self Assessment is to ensure that individuals correctly report their income and calculate the amount of tax they owe. By completing a Self Assessment tax return, you are providing HMRC with a comprehensive overview of your financial affairs.
Self Assessment also allows you to claim certain allowances and reliefs that may reduce your tax liability. Moreover, it helps HMRC identify any potential tax evasion or avoidance, ensuring that individuals pay the correct amount of tax and maintain the integrity of the UK’s tax system.
Key Deadlines
Filing deadline
The filing deadline for Self Assessment tax returns in the UK is 31 January following the end of the tax year. For example, for the tax year ending 5 April 2022, the deadline to submit your tax return is 31 January 2023. It is crucial to meet this deadline to avoid penalties and interest charges.
Payment deadline
The payment deadline for any tax owed is also 31 January. This includes the tax liability for the previous tax year as well as any payments on account for the current year (if applicable). It is important to note that late payment can result in interest charges being added to the amount owed.
Consequences of missing deadlines
Missing the Self Assessment deadlines can lead to various consequences. If you fail to file your tax return by the deadline, HMRC can impose an initial penalty of £100. This penalty increases the longer you delay, so it is crucial to submit your tax return as soon as possible.
Additionally, late payment of tax will result in interest charges being added to the amount owed. It is important to pay your tax liability by the deadline to avoid these additional charges.
Registering for Self Assessment
Who needs to register?
If your circumstances require you to complete a Self Assessment tax return, you need to register for Self Assessment with HMRC. You should register as soon as you become eligible, and ideally, no later than 5 October after the end of the relevant tax year.
How to register
Registering for Self Assessment can be done online via the HMRC website. You will need to provide your personal and contact details, as well as information about your income sources. HMRC will then issue you with a Unique Taxpayer Reference (UTR) that will be used to identify you for Self Assessment purposes.
It is important to note that if you have previously completed a Self Assessment tax return, you do not need to register again. However, you should notify HMRC if your circumstances change or if you have not received a tax return when you expected to.
Deadlines for registration
To ensure timely registration, it is recommended to register for Self Assessment as soon as you meet the eligibility criteria. However, the latest date to register for Self Assessment is 5 October after the end of the tax year for which you need to file a tax return. Missing this deadline may result in penalties, so it is crucial to register within the designated timeframe.
Gathering the Required Information
Documents needed
To complete your Self Assessment tax return accurately, you will need various documents and records. These may include:
- P60: Issued by your employer, this document outlines your income and tax deductions for the tax year.
- P45: If you changed jobs during the tax year, you will need this document from your previous employer.
- Bank statements: These will help you determine your income and expenses throughout the tax year.
- Invoices and receipts: If you are self-employed or have a business, you will need these to support your income and expenditure claims.
- Rental income details: If you have rental properties, you will need to provide details of the income and any associated expenses.
- Investment income statements: Statements from investments such as stocks, bonds, or property rentals.
Make sure you keep all relevant documents and records to support your tax return for at least five years, as HMRC may request to see them in the event of an investigation or query.
Income sources to consider
When gathering information for your Self Assessment tax return, it is important to consider all sources of income that are subject to tax. This may include:
- Employment income: This includes your salary, bonuses, and any taxable benefits received from your employer.
- Self-employment income: If you run your own business or work as a sole trader, you should include your business profits.
- Rental income: If you own properties that generate rental income, you need to report this on your tax return.
- Investment income: This includes income from dividends, interest on savings, and gains from the sale of assets like stocks or property.
- Pension income: If you receive a pension, either from the state or a private pension provider, this should be included in your tax return.
By considering all your income sources, you can accurately report your earnings and ensure compliance with HMRC requirements.
Expenses and deductions
When completing your Self Assessment tax return, you have the opportunity to claim certain expenses and deductions to reduce your tax liability. These may include:
- Business expenses: If you are self-employed, you can claim expenses that are directly related to your business, such as rent, utilities, and office supplies.
- Professional fees: If you use professional services like accountants or solicitors, you can deduct their fees from your taxable income.
- Travel expenses: If you incur travel costs for business purposes, you may be able to claim these as expenses.
- Charitable donations: If you made donations to registered charities, you can claim tax relief on these contributions.
- Pension contributions: Any contributions you make to an eligible pension scheme can be deducted from your taxable income.
It is important to keep accurate records of your expenses and provide supporting documentation when claiming deductions.

Online vs. Paper forms
Self Assessment tax returns can be completed either online or on paper. While the paper forms are still available, the online process is generally quicker, more convenient, and offers additional guidance and support.

They can provide personalized guidance and help you maximize any tax reliefs or allowances you are entitled to.
Following these tips will enhance the accuracy and efficiency of your Self Assessment tax return, reducing the risk of errors and potential penalties.
Calculating the Self Assessment Tax
Understanding tax bands and rates
To calculate your Self Assessment tax liability, it is essential to understand the UK’s tax bands and rates. In the UK, income tax is charged at different rates based on the amount of taxable income you earn. The tax bands for the current tax year (2021/2022) are as follows:
- Personal Allowance: The first £12,570 of income is tax-free.
- Basic Rate: Income between £12,571 and £50,270 is taxed at a rate of 20%.
- Higher Rate: Income between £50,271 and £150,000 is taxed at a rate of 40%.
- Additional Rate: Income over £150,000 is taxed at a rate of 45%.
These rates and bands may change from year to year, so it is important to ensure you have the most up-to-date information when calculating your tax.
Allowances and reliefs
As part of the Self Assessment tax calculation, you may be eligible for certain allowances and reliefs that can reduce your tax liability. These include:
- Personal Allowance: As mentioned earlier, the Personal Allowance allows you to earn a certain amount of income each year tax-free.
- Marriage Allowance: If you are married or in a civil partnership and one partner earns less than the Personal Allowance, they can transfer a portion of their unused allowance to the higher-earning partner.
- Capital Gains Tax Allowance: If you have made capital gains from the sale of assets, you may be eligible for an annual tax-free allowance.
- Pension reliefs: Contributions to eligible pension schemes can receive tax relief, reducing your taxable income.
Understanding and utilizing these allowances and reliefs can help minimize your tax liability and ensure you are taking full advantage of the benefits available to you.
National Insurance Contributions
In addition to income tax, you may also need to pay National Insurance Contributions (NICs). These contributions fund state benefits such as the State Pension and the National Health Service (NHS). The NICs you are required to pay depend on your employment status and the amount of your earnings.
For employees, NICs are deducted automatically from your salary by your employer. However, if you are self-employed, you will need to calculate and pay your NICs as part of your Self Assessment tax return.
It is important to consider both income tax and NICs when calculating your overall tax liability to ensure you meet all your obligations.
Payment On Account
Explanation of Payment On Account
Payment On Account is a system that requires individuals to make advance payments towards their future tax liability. If your tax bill exceeds £1,000, HMRC will usually require you to make payments on account for the following tax year. This is to ensure that your tax is paid in a timely manner and to help spread the cost of your tax bill.
The payments on account are calculated based on your previous year’s tax liability. Each payment is equal to half of the previous year’s tax bill and is due in two instalments: one on 31 January and the other on 31 July.
How and when it should be paid
The first payment on account is made alongside your balancing payment for the previous tax year. The balancing payment includes any additional tax owed for the previous year. Both the balancing payment and the first payment on account are due on 31 January.
To make the payment, you can use various methods, including online banking, debit or credit card, or bank transfer. It is important to ensure that the payment is made on time to avoid penalties or interest charges.
Exceptions and adjustments
There are certain exceptions and adjustments that may affect your payments on account. These include:
- If your tax liability for the current year is expected to be lower than the previous year, you can apply to reduce your payments on account. However, it is essential to accurately estimate your tax liability to avoid underpayment penalties.
- If you already paid more than the required payments on account, you can request a refund or have the excess amount offset against your future tax bills.
It is recommended to review your payments on account each year to ensure they accurately reflect your tax liability in the current year and make any necessary adjustments.
Common Self Assessment Mistakes
Forgetting to include all income
One common mistake when completing the Self Assessment tax return is forgetting to include all sources of income. Many individuals may overlook income from freelance work, rental properties, or investments. However, it is crucial to disclose all income to HMRC to avoid potential penalties for non-disclosure.
To prevent this mistake, ensure you have a comprehensive understanding of all your income sources and refer to your documentation and records when completing your tax return.
Incorrectly claiming expenses
Another common error is incorrectly claiming expenses that are not allowable or not properly supported. Understandably, individuals may try to maximize their deductions to reduce their tax liability. However, it is essential to only claim legitimate expenses that are directly related to your business or employment.
When claiming expenses, keep accurate records and ensure you have supporting evidence such as receipts or invoices. Remember that HMRC may request to see these records to verify your claims, so it is important to maintain organized and accurate records.
Inaccurate tax calculations
Calculating your tax liability accurately is crucial to avoid underpayment or overpayment. Mathematical errors or incorrect input of figures can result in incorrect tax calculations. This can lead to penalties for underpayment or inefficient use of available tax reliefs.
To minimize this risk, double-check all your calculations and consider using reliable tax software that can help with accurate calculations and error-checking.
Penalties for Inaccurate or Late Filing
Late filing penalties
Failing to submit your Self Assessment tax return by the deadline can result in penalties. The initial penalty is £100, and additional penalties may be imposed if the delay continues. The longer you delay, the more the penalties accrue:
- After 3 months: £10 per day, up to a maximum of £900
- After 6 months: Either £300 or 5% of the tax due, whichever is higher
- After 12 months: Either £300 or 5% of the tax due, whichever is higher
These penalties can quickly add up and significantly increase the amount you owe to HMRC. Therefore, it is essential to file your tax return by the deadline.
Accuracy-related penalties
If HMRC determines that your tax return is inaccurate or contains errors, it may impose accuracy-related penalties. These penalties can be up to 100% of the tax underpaid, depending on the severity and circumstances of the inaccuracy. It is, therefore, crucial to take care when completing your tax return and ensure the information provided is true and accurate.
Appealing against penalties
In certain circumstances, you may be able to appeal against penalties imposed by HMRC. If you have a reasonable excuse for missing the filing deadline or have valid grounds to dispute an accuracy-related penalty, you can submit an appeal.
Examples of valid excuses for missing the filing deadline include serious illness, bereavement, or unexpected events beyond your control. It is important to provide supporting evidence and submit your appeal as soon as possible.
HMRC will review your appeal and consider the circumstances before making a decision. It is advisable to seek professional advice if you are uncertain about the appeal process or require assistance in preparing your appeal.
