Do I Need to Register for Self Assessment Tax if I’m Not Self-Employed?

Updated: Dec 28, 2023

If you're in Self-Assessment, you must submit a tax return every year. You have to declare your income or capital gain and request any allowances or reliefs. A majority of people don't have to register with the Self-Assessment tax if they are not self-employed. However, there are some exceptions. We will explain how this could be applicable to you if you are Not Self-Employed.


In the UK, the Self Assessment tax system requires individuals and businesses to report their income and calculate their tax liabilities. While commonly associated with self-employment, there are situations where individuals not self-employed must also register for Self Assessment. Understanding these scenarios is crucial for UK taxpayers to ensure compliance and avoid potential fines.


What is a Self-Assessment Tax Return?

If you're self-employed or have other multiple sources of income you'll most likely have to file a self-assessment return for tax purposes. Self-assessment reports to HMRC what amount of money you've earned this year, along with other information regarding your financial situation, to ensure that HMRC will be able to calculate your tax liability or the national insurance (NI) you are liable for. This is also referred to as "filing your annual tax returns: and, you can also complete it online. The phrase "self-assessment" does not suggest that you need to do it all by yourself. You could hire a tax accountant to take care of all the tasks for you. A tax accountant is able to fill out the form accurately for you and help you minimize the amount of tax you need to pay by avoiding paying any unpaid taxes.


After you've filed your tax returns, HMRC will calculate the amount of tax to be paid. They will then send you your notice of assessment and you can check it through your online account at the government's website. Then You have the option of paying the tax, typically by debit card online or by post.


Recent Changes in Self-Assessment Criteria

As of May 2023, HM Revenue and Customs (HMRC) announced significant changes to the income threshold for filing a self-assessment tax return. Previously set at £100,000, the threshold has been raised to £150,000, effective from the 2023/24 tax year. This change potentially alters the landscape for many taxpayers, especially those with high incomes but not self-employed.


Who Needs to Register for Self-Assessment?

Registration for Self Assessment is not solely for self-employed individuals. Various other circumstances necessitate registering for Self Assessment using form SA1. These circumstances include:


  • Income from Land and Property in the UK: Individuals receiving rental or other income from property in the UK must register for Self Assessment.

  • Taxable Foreign Income: If you have income from abroad that is liable for UK tax, registration is required.

  • High Income with Child Benefit: Households with an adjusted net income over £50,000 and receiving Child Benefit payments must register.

  • Yearly Income over £100,000: Regardless of the source, an annual income exceeding £100,000 triggers the need for registration.

  • Income from Trusts or Settlements: Receiving income from a trust or a settlement also requires Self Assessment registration.

  • Untaxed Income Not Collected Through PAYE: If you have untaxed income that cannot be collected via your PAYE tax code, you must register.

  • Capital Gains Tax Liabilities: Individuals with Capital Gains Tax to pay are also required to register​​.


Importance of Timely Registration

The deadline for registering for Self Assessment is a critical date to keep in mind. If you fall into any of the above categories or other situations requiring a tax return, you must register by 5 October following the end of the tax year for which you need to file a return. For instance, for the tax year 2022 to 2023, the registration deadline would be 5 October 2023​.

This includes your full name, postal address (which can be outside of the UK), date of birth, daytime telephone number, and UK National Insurance number (if you have one). Additionally, you'll need to explain why you need to register for Self Assessment and the date this requirement started​.


4. Accessing the Government Gateway

To fill in and submit Form SA1 online, you'll need to access the Government Gateway. This requires either signing in with your existing user ID and password or using your email address to get a confirmation code for signing in.

When you're the first to register for the HMRC web-based services (which you'll be using to prepare the SA tax returns) you'll be provided with the activation number. This could take a few weeks to be delivered and you should make sure you sign up on time to file your tax return.


Consequences of Not Declaring Self Assessment in the UK


The Gravity of Non-Declaration

Not declaring income for Self Assessment in the UK is a serious matter, often classified as tax evasion. This crime can range from minor under-reporting to significant evasion of due taxes. Importantly, even unintentional failure to declare taxable income falls under this category. The repercussions of non-disclosure, whether deliberate or accidental, are substantial and varied, depending on the specifics of the case​.


Penalties for Non-Declaration

The most common consequence of not declaring income is a financial penalty. HM Revenue & Customs (HMRC) primarily focuses on recovering any unpaid taxes. In addition to repaying the owed tax, individuals can face fines up to 200% of the tax due. This punitive measure emphasizes the severity with which HMRC views non-compliance​.


Late Filing and Payment Penalties

Failure to meet deadlines for filing tax returns or making payments also results in penalties. A late filing penalty of £100 is charged if your tax return is up to three months late, with additional charges for longer delays or late tax bill payments. Interest is also charged on late payments, further increasing the financial burden​.


Risk of Prosecution and Imprisonment

In extreme cases, tax evasion can lead to criminal prosecution, with potential jail time. While sentences for tax evasion generally do not exceed seven years, there's no upper limit, allowing for more severe punishments in particularly egregious cases​.


HMRC's Detection Methods

HMRC employs sophisticated methods to detect undeclared income. They use advanced software, like 'Connect', to analyze large datasets for inconsistencies indicative of tax evasion. HMRC can also initiate investigations based on suspicions about the accuracy of tax returns or tax credit applications. Their access to financial records from banks, insurance brokers, and various companies, including Airbnb and crypto exchanges, enhances their ability to uncover undeclared income​.


Non-declaration of income for Self Assessment in the UK is a matter taken very seriously by HMRC, with consequences ranging from financial penalties to potential imprisonment. Understanding the importance of declaring all taxable income and adhering to Self Assessment deadlines is crucial for UK taxpayers. Failure to comply not only risks significant financial penalties but also the possibility of criminal prosecution. It's imperative for individuals to be thorough and accurate in their tax affairs, ensuring all relevant income is declared to HMRC to avoid these severe consequences.


How HMRC Detects Those Who Don't Declare Self-Assessment


Connect: HMRC's Digital Sleuth

The cornerstone of HMRC's strategy for detecting undeclared income is a sophisticated software system known as Connect. Launched in 2010, Connect is designed to analyze massive amounts of data, uncovering discrepancies between declared income and actual financial status. This system can identify patterns and associations in data that may initially appear unrelated, helping to reveal instances of tax evasion. For example, if your lifestyle expenditures exceed what you report as income, Connect can flag this inconsistency, potentially triggering an investigation​​​.


Wide-Ranging Data Sources

Connect integrates information from various sources, significantly enhancing HMRC's ability to detect undeclared income. These sources include:


  • Government departments and agencies like the DVLA, DWP, Land Registry, Border Agency, and Companies House.

  • Tax returns, including income tax, VAT, corporation tax, and PAYE.

  • Financial records from banks, building societies, online payment providers, credit card accounts, credit reference agencies, and crypto asset platforms.

  • Information from international financial records through global initiatives against tax havens.

  • Online sales and property websites, such as Amazon, eBay, Airbnb, Rightmove, and Zoopla.

  • Social media platforms, including Facebook, Instagram, LinkedIn, and Twitter.

  • Other peripheral sources like flight sales, passenger manifests, the Charities Commission, and even Google Earth​​.


HMRC's Proactive Campaigns and Public Involvement

HMRC actively searches for non-registered businesses and unreported income. This includes specific campaigns targeting particular industry sectors to uncover undeclared business activities and moonlighting. HMRC also encourages public involvement through the Tax Evasion hotline, where individuals can anonymously report suspected tax evasion. These efforts, combined with the extensive use of Connect, create a formidable detection network​​​.


Legal Powers and Consequences

HMRC has extensive legal powers to gather information. This includes details of debit and credit card sales and online selling activities. In cases of tax evasion, HMRC can impose penalties up to 100% of the owed tax, with interest on unpaid taxes adding to the financial burden. In severe cases, HMRC may even resort to using the Proceeds of Crime Act against individuals, significantly increasing the cost of tax evasion. It's worth noting that although the number of prosecutions for tax evasion is relatively small, HMRC expects this to rise, emphasizing the increasing risk of non-compliance​.


In summary, HMRC employs a multi-faceted approach to detect those who don't declare self assessment in the UK. The use of sophisticated software like Connect, combined with a variety of data sources, public involvement, and proactive campaigns, creates a robust system for uncovering undeclared income. The consequences of being caught can be severe, including heavy financial penalties and, in extreme cases, legal prosecution. This comprehensive detection strategy underscores the importance of complete and accurate income declaration for all UK taxpayers.
