Many people wonder, when does the financial year in the UK start? This is an important question. Knowing the start of the financial year helps with taxes and money planning.
What is a Financial Year?
A financial year is a period of 12 months. It is used by the government and businesses for money matters. It helps in keeping track of income, expenses, and taxes.
The financial year is not the same as the calendar year. It starts and ends on different dates. This is why it can be confusing.
Start Date of the Financial Year in the UK
The financial year in the United Kingdom starts on 6th April every year. It ends on the 5th of April the next year.
For example, the financial year 2023/2024 started on 6th April 2023 and will end on 5th April 2024.
Why Does the Financial Year Start on 6th April?
This date might seem strange. Why not 1st January or 1st April? The answer is in history.
Long ago, the UK used a different calendar called the Julian calendar. The new calendar, called the Gregorian calendar, started in 1752.
When switching to the new calendar, the government moved the start of the tax year to 6th April. This date matched the old calendar’s start.
So, the financial year start date is a tradition from history. It has stayed the same for many years.
What Does the Financial Year Affect?
The financial year is important for many reasons:
- Calculating income tax
- Planning business accounts
- Setting budgets for companies
- Government financial reports
If you are employed or run a business, you must understand the financial year.

How Does the Financial Year Start Affect Tax Payments?
Your income during the financial year decides how much tax you owe. It means you pay tax on money earned between 6th April and 5th April.
You use this period to fill in your tax return. It shows how much money you made and how much tax you should pay.
Financial Year for Businesses
Most businesses in the UK also follow the 6th April to 5th April financial year. But not all.
Some companies can choose a different financial year. This is called a “financial accounting year.” But for tax purposes, the government uses the 6th April to 5th April year.
