A financial year end marks the conclusion of a 12-month period used by businesses to track, report and assess their financial activity. It is the point at which businesses stop recording income and expenses for the year and begin preparing their financial statements.
This process is fundamental to business operations. It involves closing the books, reviewing performance and planning for the year ahead. The financial year end provides a natural checkpoint that allows business owners and stakeholders to measure business performance and identify where they can make improvements.
Financial Year End Importance
The financial year end is a critical part of running any business. One of its main purposes is to support transparency and accountability. By preparing financial statements, businesses offer a clear snapshot of their financial health.
In the UK, it is a legal obligation for companies to file their annual accounts with Companies House. This legal framework ensures that all incorporated businesses are held to a consistent reporting standard. Failure to submit these documents on time can result in penalties or enforcement action.
Beyond compliance, year-end reporting helps business owners understand their profit margins, cash flow and expenses.
Choosing a Financial Year End Date
While Companies House sets deadlines for filing based on your accounting reference date, businesses typically have the freedom to choose their own financial year end date. HMRC expects tax reporting to align with the chosen accounting period.
Many opt to align it with the government’s financial year, which runs from 1st April to 31st March. Others prefer the tax year, which spans from 6th April to 5th April the following year. Choosing the right date can help streamline processes.
For example: Aligning your financial year with the tax year can reduce confusion when submitting your tax return. It also simplifies comparisons between years, making trends easier to spot and analyse.
For new companies, the first financial year often ends on the last day of the month in which the business was incorporated. However, companies can apply to change their accounting reference date if another period would be more practical.
The Financial Year End Process Explained
The financial year end involves a structured process to ensure all figures are correct and complete. Here are the steps businesses typically follow:
1. Review Transactions – Check all financial activity over the year. Ensure that all sales, purchases and expenses are accurately recorded.
2. Reconcile Accounts – Match internal financial records with external sources such as bank statements, loan agreements and supplier invoices.
3. Adjust Entries – Add any missing income or expenses. Adjust for items like depreciation, accrued liabilities and prepayments.
4. Prepare Financial Statements – Compile reports such as the Balance Sheet, Income Statement (also known as the Profit and Loss Account) and Cash Flow Statement.
5. File Reports – Submit annual accounts to Companies House and a Company Tax Return with full accounts to HMRC within the required deadlines.
Each of these steps contributes to presenting a true and accurate picture of the company’s financial position.
Benefits of a Smooth Year End Process
Firstly, it ensures that the business meets all legal and tax-related responsibilities. Avoiding penalties for late filings or errors can save time, money and stress.
Secondly, it provides a solid foundation for growth. Accurate reports also help identify strengths and weaknesses, which can aid strategic planning. Investors and lenders often rely on these figures when making decisions, so well-prepared accounts can boost your credibility.
Additionally, the process supports better budgeting. Knowing your costs and revenues in detail helps you set realistic goals and plan for future investments.
How the Tax Year Differs
The tax year and the financial year are not the same, although they are closely related.
The UK tax year runs from 6th April to 5th April. This is the period HMRC uses to assess and collect taxes from individuals, including employees directors and sole traders.
For example: The 2024/25 tax year ends on 5th April 2025. From 6th April onwards, you can begin submitting your Self Assessment tax return. The deadline for online filing and paying any outstanding tax is 31st January 2026.
Limited companies usually follow a different schedule based on their financial year. The end of the accounting period determines the tax payment and reporting deadlines, which may not align with the tax year.
Why Doesn’t the UK Use the Calendar Year?
It may seem unusual that the UK’s tax year doesn’t follow the calendar year. The reason is historical.
In 1752, Britain adopted the Gregorian calendar, replacing the outdated Julian calendar. This change created an 11-day gap.
To avoid losing tax revenue during the transition, the government moved the start of the tax year from 25th March to 5th April, then to 6th April in 1800. The date has remained unchanged since, despite modern developments.
