What is a Self Assessment Tax Return?

A Self Assessment tax return is a form submitted to HMRC each year to declare your income and calculate how much Income Tax and National Insurance you owe. Unlike employees taxed through PAYE, self-employed individuals, landlords, and anyone with untaxed income must report it themselves directly to HMRC.

Who Needs to File a Self Assessment Tax Return?

You are required to complete a Self Assessment return if any of the following apply to the current tax year (6 April to 5 April):

You are self-employed or a sole trader with trading income over £1,000

You have rental income from UK or overseas property

You have untaxed income — dividends, savings interest, or foreign earnings

You are a company director

You or your partner received Child Benefit and either of you earned over £50,000

Self Assessment FAQs

Who needs to file a Self Assessment tax return?

You must file if you are self-employed, have rental income, received untaxed income (dividends, savings, foreign income), are a company director, or you or your partner received Child Benefit when either earned over £50,000. If unsure, contact us and we'll advise you within one working day.

What is the Self Assessment filing deadline?

The online filing deadline is 31 January following the tax year end (5 April). Missing this date triggers an automatic £100 HMRC penalty, increasing if the return remains unfiled after 3, 6, and 12 months. Tax2u files well ahead of the deadline to protect you.

How much does it cost to have Tax2u file my return?

Packages start at £135+VAT for a Basic Return (one income source, income up to £12,000/year). We also offer Multi Income and Full Return packages for more complex cases, plus an MTD monthly package at £30+VAT/month. You choose your plan at the end of sign-up — no payment is taken until you have confirmed.

I'm employed under PAYE but have freelance income. Do I need Self Assessment?

Yes. If you have any income not taxed at source — freelance earnings, rental income, side business revenue — you must declare it via Self Assessment regardless of your employment status. Tax2u handles mixed-income returns for employed individuals regularly.

What documents do I need to provide?

Typically: your P60 or P45 (if employed), self-employment income and expense records, rental statements, dividend certificates, and bank statements for any untaxed interest. After sign-up, your accountant sends a personalised document checklist via your Tax2u dashboard.
