Self-Assessment Tax Returns are a crucial aspect of the UK tax system, allowing individuals and businesses to report their income and calculate the tax owed to HM Revenue & Customs (HMRC). This guide will help you understand the process, deadlines, and consequences of non-compliance, ensuring you stay on top of your tax obligations.
What is a Self-Assessment Tax Return?
A Self-Assessment Tax Return is a system through which taxpayers report their income, gains, and allowable expenses to HMRC. Unlike the Pay As You Earn (PAYE) system, where tax is automatically deducted from salaries, Self-Assessment requires individuals to calculate and pay their own taxes.
This system applies to various groups, including:
- Self-employed individuals
- Company directors
- Landlords earning rental income
- Investors with significant dividends or capital gains
- Individuals earning over £100,000 annually
- Partners in a business partnership
If you fall into any of these categories, filing a Self-Assessment Tax Return is mandatory.
Key Deadlines for Self-Assessment
Missing a deadline can lead to penalties, so it’s essential to stay aware of these key dates:
| Event | Deadline |
|---|---|
| Register for Self-Assessment | 5th October (after the tax year ends) |
| Submit paper tax return | 31st October |
| Submit online tax return | 31st January |
| Pay tax owed | 31st January |
The UK tax year runs from 6th April to 5th April of the following year. For example, for the 2023/24 tax year, your online tax return is due by 31st January 2025.
