Self assessment
How do you complete a self assessment tax return? Understanding this process is important if you’re self employed or earn income outside of traditional employment. A self assessment tax return allows you to report your earnings and calculate the tax you owe to HM Revenue and Customs (HMRC).
Correctly submitting your self assessment guarantees that you fulfil your legal obligations and stay out of trouble. We'll simplify the entire process in this blog post so that anyone may follow along with ease. We'll go over everything you need to know, from signing up for self assessment to obtaining the required data and filing your return.
Whether you’re new to self assessment or looking for a refresher, our guide will help you navigate the requirements with confidence. Let’s get started on ensuring you complete your self-assessment tax return accurately and on time.
A self assessment tax return is a process used by HM Revenue and Customs (HMRC) in the UK to collect income tax from individuals who earn money outside of traditional employment. It allows taxpayers to report their income and calculate how much tax they owe. But who exactly needs to file one?
Self-Employed Individuals: If you run your own business or work as a freelancer, you need to file a self-assessment to report your earnings.
Part-Time or Casual Workers: If you have additional income that is not taxed at source, such as freelance work or side incomes, you must declare this income.
Landlords: If you earn rental income from property, you’re required to file a self-assessment tax return.
High Earners: Individuals earning over £150,000 must submit a self-assessment.
Directors of Companies: If you are a company director and receive income from your role, you need to file.
If you follow these thorough steps, completing a self assessment tax return can be manageable:
Register for self assessment with HM Revenue and Customs (HMRC) to start the procedure. For those who work for themselves or must submit a tax return, this is essential. The HMRC website allows you to register online, and in order to avoid fines, you must do it before the registration deadline. A Unique Taxpayer Reference (UTR), which is important for your tax return, will be provided to you during registration.
Before you begin your tax return, gather all required documentation. Your UTR, bank statements, and documentation of any other sources of income, such as freelance or rental income, are included in this. Having these documents on hand will make your return process go more smoothly.
Create an account with your Government Gateway ID to access the HMRC online service. Create an account if you don't already have one by entering your email address and completing the verification procedures. Having this account is important for handling your tax situation.
Start by completing the SA100, the primary form, which asks for information about your earnings, payout, and any relevant deductions. Report all sources of income accurately to guarantee that tax laws are followed.
Check all entries for accuracy after filling out the form. To reduce mistakes, make sure you have listed all of your sources of income and any permitted costs.
After you are confident that all the information is accurate, use your HMRC account to online file your tax return. To prevent late filing fines, make sure you complete this before to the submission date.
HMRC will determine your tax liability and let you know how much is owed after submission. To avoid interest or penalties for late payments, make sure you pay this amount before the deadline.
Staying on top of deadlines is important for a smooth self-assessment process. Here’s a clear points showing the important dates you need to keep in mind:
Register by October 5: If you are self-employed or have other untaxed income, you must register with HMRC by this date to avoid penalties.
Paper Tax Return October 31: If you choose to file your tax return using a paper form, it must be submitted by this date.
Online Tax Return January 31: This is the final deadline for submitting your self assessment tax return online for the previous tax year.
Pay Tax Bill January 31: Any tax owed for the previous tax year must be paid by this date to prevent interest charges and penalties.
Second Payment on Account July 31: If applicable, make your second payment on account for the current tax year by this date to stay updated.
By keeping these deadlines in mind, you can ensure that your self assessment is filed correctly and on time, helping you avoid unnecessary stress and financial penalties. Plan and mark these dates on your calendar.
To complete your self assessment tax return, gather the following necessary information:
Unique Taxpayer Reference (UTR): Your identity for HMRC.
Income Documentation: Payslips, and invoices for self-employment earnings.
Bank Statements: To track interest and any other income received.
Expense Records: Receipts for allowable business expenses, such as supplies and travel costs.
Rental Income Details: Information about properties you rent, including income and related expenses.

First, download the SA100 form from the HMRC website or access it through your online account. This form is important for reporting your income and calculating your taxes.
Provide your personal details, including your Unique Taxpayer Reference (UTR) and National Insurance number.
Report all sources of income, including salary, self-employment earnings, and any untaxed income such as allowance or interest. Be accurate to avoid penalties.
Include details of any allowable expenses related to self-employment, which can reduce your taxable income.
Depending on your income sources, you may need to fill out supplementary pages.
Use SA103 for self-employment income.
Use SA102 for Employee or Company Director.
Use SA104 for Business Partnerships.
Use SA105 if you have rental income from properties.
Use SA106 For foreign income or gains.
Use SA108 for capital gains from asset sales.
Use SA109 for non-UK residents.
Each supplementary page requires specific details about the income type and any related expenses. Ensure you fill these out accurately to reflect your financial situation.
Submitting your self assessment tax return can be challenging, but accuracy can be ensured by avoiding these typical errors:
Missing Deadlines: To prevent fines, always remember the due dates for submissions and payments.
Inaccurate Personal Information: To avoid processing delays, make sure your name, address, and UTR are right.
Math Errors: Verify all computations twice because even minor arithmetic errors can result in an inaccurate tax liability.
Ignoring Income Sources: To avoid penalties, include all sources of income, including rental income and freelancing.
Ignoring Deductions: Remember that you can highly reduce your taxable income by claiming allowed expenses.
How to Pay Your Tax Bill for Self-Assessment To avoid penalties, you must pay your self assessment tax bill. Here's how to accomplish it:
Online Payment: For immediate processing, sign into your HMRC account and make a direct payment using a credit or debit card.
Bank Transfer: Make sure to provide your payment reference when transferring money to HMRC using your bank's online facility.
Direct Debit: To help you handle bigger bills over time, set up a direct debit for automatic payments.
Cheque: If you prefer, send a cheque made out to HM Revenue and Customs, but allow time for it to reach HMRC by the deadline.
Don't panic if you notice a mistake on your self assessment tax return or if you miss a deadline. This is what you should do:
Send in as soon as you can: To reduce penalties, file your return right away if you missed the filing date.
Fix Errors: You can either tell HMRC directly or file an updated return online if you find a mistake after filing.
Pay any taxes that are due: To prevent interest fees, make sure you pay any taxes that are owed.
Speak with HMRC: Ask HMRC for advice if you're unclear about what to do next.
Having the appropriate tools and information can make navigating self assessment easier. Here are a few useful choices:
HMRC Website: Detailed instructions and frequently asked questions on self assessment are available on the official HMRC website.
Tax software: Applications such as Nomi make filing easier and reduce the possibility of mistakes.
Online Calculators: Before filing, estimate your tax liability using tax calculators.
