Understanding the UK Tax Year and Filing Deadlines

The UK tax year runs from April 6th to April 5th of the following year. It’s essential to be aware of the specific deadlines associated with this period:

Electronic Tax Returns: Must be filed by January 31st following the end of the tax year.
Paper Tax Returns: Should be submitted by October 31st following the end of the tax year.

Unlike the U.S. system, the UK does not grant automatic extensions for late submissions. Late filings are assessed by HM Revenue & Customs (HMRC) on an individual basis and only under certain conditions.

The PAYE System: An Overview

Similar to the U.S. payroll system, the UK’s Pay As You Earn (PAYE) system deducts taxes directly from your earnings, including:

Income Tax: Levied on salaries, wages, business income, and investment income.
National Insurance Contributions: Contributions that fund state benefits and the National Health Service (NHS).

The specific tax rates applied are subject to change based on your total earnings.

Tax Considerations for Married Couples

In the UK, married couples are required to file individual tax returns; joint filing is not permitted. However, couples may benefit from the Marriage Allowance, which allows one partner to transfer a portion of their personal allowance to the other, potentially reducing their tax liability.
