What is a Tax Year in UK

Understanding the Tax Year in the UK: A Comprehensive Guide

Navigating the complexities of the UK tax system can be daunting, especially if you’re new to the country or just starting to manage your finances. One of the fundamental concepts you need to grasp is the tax year. This blog will delve into what a tax year is, why it’s important, how it affects your finances, and everything else you need to know to stay compliant and make the most of your tax planning.

What is a Tax Year?

In the UK, the tax year is the period during which income tax is calculated and levied. It is also known as the fiscal year or financial year. Unlike the calendar year, which runs from January 1 to December 31, the UK tax year runs from April 6 to April 5 of the following year. This unique timeframe has historical roots dating back to the 18th century, when the UK switched from the Julian calendar to the Gregorian calendar.

For example, the tax year for 2023/24 runs from April 6, 2023, to April 5, 2024.

Why Does the UK Tax Year Start on April 6?

The UK tax year’s unusual start date can be traced back to 1752. Before this, the UK used the Julian calendar, which was 11 days behind the Gregorian calendar used by most of Europe. To align with the Gregorian system, the UK skipped 11 days in September 1752. However, the Treasury decided to keep the tax year’s end date as April 5 to avoid losing revenue. This adjustment resulted in the tax year starting on April 6.

Key Dates in the UK Tax Year

Understanding the tax year involves knowing the key dates and deadlines that apply to individuals and businesses. Here are some of the most important dates to keep in mind:

1. April 6: Start of the new tax year.
2. April 5: End of the tax year.
3. January 31: Deadline for filing your Self Assessment tax return online and paying any tax owed for the previous tax year.
4. October 31: Deadline for filing a paper Self Assessment tax return.
5. July 31: Second payment on account deadline for Self Assessment taxpayers.
6. December 31: Deadline for filing a tax return if you want HMRC to collect tax owed through your PAYE tax code (if applicable).

How Does the Tax Year Affect You?

The tax year is a critical period for individuals, businesses, and the government. Here’s how it impacts different aspects of your financial life:

1. Income Tax

• Your income tax liability is calculated based on your earnings during the tax year.
• The UK operates a Pay As You Earn (PAYE) system, where most employees have their income tax deducted automatically by their employer.
• If you’re self-employed or have additional income, you’ll need to file a Self Assessment tax return to declare your earnings and pay any tax due.

2. Personal Allowance

• The personal allowance is the amount of income you can earn tax-free each tax year. For the 2023/24 tax year, the personal allowance is £12,570.
• If your income exceeds £100,000, your personal allowance is gradually reduced.

3. Tax Bands and Rates

• The UK uses a progressive tax system, meaning the rate of tax increases as your income rises. The tax bands and rates for 2023/24 are:
• Basic rate: 20% on income between £12,571 and £50,270.
• Higher rate: 40% on income between £50,271 and £125,140.
• Additional rate: 45% on income above £125,140.
• Different rates apply to dividends and savings income.

4. National Insurance Contributions (NICs)

• NICs are another form of tax paid by employees, self-employed individuals, and employers. The amount you pay depends on your earnings and employment status.
• NICs fund state benefits, including the State Pension.

5. Tax-Free Savings and Investments

• The tax year is relevant for tax-efficient savings and investment accounts, such as Individual Savings Accounts (ISAs) and pensions.
• Each tax year, you receive an ISA allowance (e.g., £20,000 for 2023/24) and a pension annual allowance (£60,000 for 2023/24), which reset at the start of the new tax year.

6. Capital Gains Tax (CGT)

• If you sell an asset (e.g., property, shares) and make a profit, you may need to pay CGT. The tax year determines your CGT allowance and the deadline for reporting and paying the tax.

7. Inheritance Tax (IHT)

• IHT is levied on the estate of someone who has passed away. The tax year affects the nil-rate band (the threshold below which no IHT is due) and the deadlines for paying the tax.

Tax Year for Businesses

For businesses, the tax year is equally important. Here’s how it applies:

1. Corporation Tax

• Companies pay Corporation Tax on their profits. The tax year for Corporation Tax is the same as the financial year (April 1 to March 31).
• Businesses must file a Company Tax Return and pay any tax due within nine months and one day of the end of their accounting period.

2. VAT (Value Added Tax)

• VAT-registered businesses must submit VAT returns and pay any VAT owed to HMRC. The frequency of VAT returns depends on the business’s turnover and accounting scheme.

3. Payroll and PAYE

• Employers must report payroll information to HMRC in real time through the Real Time Information (RTI) system. The tax year determines the deadlines for submitting payroll reports and paying any tax and NICs due.

Tax Planning and the Tax Year

Effective tax planning is essential to minimize your tax liability and make the most of available allowances and reliefs. Here are some tips:

1. Use Your Allowances

• Maximize your personal allowance, ISA allowance, and pension contributions before the end of the tax year.
• Consider transferring assets between spouses to make use of both partners’ allowances.

2. Plan for Capital Gains

• Use your CGT allowance (£6,000 for 2023/24) to sell assets tax-free.
• Consider timing the sale of assets to spread gains over multiple tax years.

3. Claim Tax Reliefs

• Claim tax reliefs for expenses related to your employment, self-employment, or charitable donations.
• Use Marriage Allowance if eligible, which allows a spouse to transfer part of their personal allowance to their partner.

4. Prepare for Self Assessment

• Keep accurate records of your income and expenses throughout the tax year.
• File your Self Assessment tax return early to avoid last-minute stress and potential penalties.

Common Mistakes to Avoid

1. Missing Deadlines
• Late filing or payment can result in penalties and interest charges. Set reminders for key deadlines.
2. Underreporting Income
• Failing to declare all your income can lead to fines and investigations by HMRC.
3. Overlooking Allowances
• Many taxpayers miss out on valuable allowances and reliefs. Stay informed about what’s available.
4. Poor Record-Keeping
• Keep detailed records of your income, expenses, and tax-related documents. This will make filing your tax return much easier.

How to Stay Compliant

1. Register with HMRC
• If you’re self-employed or have additional income, register for Self Assessment with HMRC.
2. Use HMRC’s Online Services
• HMRC’s online portal allows you to file tax returns, check your tax code, and manage your tax affairs.
3. Seek Professional Advice
• If you’re unsure about your tax obligations, consult a qualified accountant or tax advisor.
