What is self assessment?

Self-assessment is a system used by HMRC to collect income tax from self-employed individuals, company directors, and others whose income isn't automatically taxed through PAYE (Pay As You Earn). It's essential to complete your self-assessment tax return correctly and on time to avoid penalties. This includes declaring any untaxed income, such as earnings from freelance work, rental income, or capital gains from selling assets.

Who Needs to File a Self-Assessment Tax Return?

You may need to submit a self-assessment tax return if you fall into any of the following categories:

  • Self employed individuals (sole traders) earning more than £1,000 in the tax year.
  • A company director receiving untaxed income such as dividends.
  • Anyone receiving income from rental properties or savings, investments, or dividends.
  • Those earning above £100K in PAYE income.
  • Individuals who have capital gains from selling property or investments.
  • Individuals who wish to claim specific tax reliefs, such as for pensions or charitable donations.

If any of these apply to you, filing a self assessment tax return UK is mandatory. Our team of professional self assessment accountants is here to guide you through the process, ensuring that everything is accurately reported and filed on time.

Frequently asked questions

Our tax help package includes checking your money coming in and going out, figuring out how much tax you owe, submitting the tax form, and talking to the tax office for you. We take care of everything related to your taxes.

To sign up for self-assessment tax returns in the UK, check if you need to, then go to the HMRC website to register. They'll give you a special reference number. Use a code they send you to set up your online account. Finally, fill in your income and expenses either online or on paper.
