Understanding Self-Assessment: A Simple Guide for UK Tax Filers

Introduction:

When it comes to self-assessment, navigating the UK’s tax system might feel like navigating a complicated maze. If you have more than one source of income, whether as a freelancer, a small business owner, or from any other source, you must be familiar with self-assessment to comply with HMRC rules and avoid fines.

What Does Self-Assessment Mean?

HMRC provides a self-assessment method to collect income tax from individuals who do not have their taxes automatically withheld from their pay. You are responsible for reporting your income and determining your tax liability annually. The best way to put it is that you are accepting full responsibility for reporting your income and paying your fair share of taxes.

Who Needs to Register for Self-Assessment?

A self-assessment tax return isn't necessary for everyone. Registration for self-assessment is usually required if you:

• Are self-employed with a yearly income of over £1000
• Are a partner in a company that generates more than £1,000 in revenue
• Make money via investments, rental properties, or anything else
• Have an annual income of more than £100,000
• Receive money from overseas that must be declared
• Need to claim tax relief or report additional income not captured through PAYE
  
  
  

Self-Assessment Registration Process

You can complete the self-assessment registration process online at HMRC's website by following the below steps. You can pay self-assessment after registration.

1. Step one is to visit the HMRC website and register for an online account. This will allow you to access government services.
   2. After that, provide your personal information, which must include your National Insurance number in addition to other mandatory details.
   3. After providing your details, confirm your identification. Additional procedures may be required by HMRC for verification.
   4. At the end, get your Unique Taxpayer Reference (UTR). When you get future tax notifications, you will need this 10-digit number.
   
   Expert advice: Register immediately. If you became self-employed during a specific tax year, you must register online by the 5th of October after that year's conclusion.

Account Setup and Submitting Your Tax Return

Upon completion of the registration process, HMRC will provide you with a letter containing instructions on how to establish your Government Gateway account, as well as your Unique Taxpayer Reference (UTR) number. Upon completion of this process, you will receive an activation code to complete the account setup.

Online submission

You can submit your tax return by using the free HMRC Self Assessment online service on the GOV.UK website.

Applications submitted via mail

If you opt to submit your application via mail, you will be required to download Form SA100 from the gov.uk website.

Additionally, it is possible to obtain an assistance form that provides instructions on how to complete a paper tax return.

Once you have completed the form, please return it to the HMRC by the deadline of October 31.
