Financial year-end: Everything you need to know

The financial year-end marks the conclusion of a company’s accounting period, where all financial records are closed off for reporting and tax purposes. For some, the financial year coincides with the fiscal year. Others may follow a separate accounting year-end, such as the end of the calendar year, giving them two closing periods to manage. 

In these cases, having a clearly defined year-end and quarter-end close process can help ensure consistency, accuracy, and compliance throughout the reporting cycle.

In the UK, the financial year typically runs from 6th April to 5th April of the following year. Important key dates include:

• 6th April: Start of the new financial year.
• 31st January: Deadline for submitting self-assessment tax returns for the previous financial year.
• 5th April: End of the financial year.
• 19th May: Deadline for submitting final PAYE returns for employers.

These dates are crucial for tax reporting, filing returns, and planning business finances effectively. Businesses should also be aware of other important financial reporting deadlines throughout the year.

The UK financial year starts in April due to historical factors dating back to the 18th century. The calendar change from the Julian to the Gregorian system in 1752 shifted the new tax year from March 25th (the old New Year) to April 5th, and later to April 6th.

This was done to maintain the same number of days for tax collection after adjusting for the calendar reform. The April start has since remained, forming the foundation for tax assessments, business accounting, and government financial planning.

Companies choose their fiscal year-end based on several key factors, including:

• Industry cycles: Aligning the fiscal year-end with slower business periods or natural business downtime.
• Seasonality: Choosing a period when operations are less busy, simplifying the process of closing accounts.
• Tax considerations: Ensuring tax reporting is efficient and aligns with government deadlines.
• Parent company schedules: Aligning with the fiscal year-end of parent companies for easier consolidation.
• Regulatory requirements: Meeting legal or industry-specific financial reporting obligations.

It is vital that you know when your fiscal year ends so you can give yourself enough time to prepare.

Yes, it is possible to change your financial year-end. Changing your financial year can be a strategic decision for a business, allowing for better alignment with operational cycles, industry standards, or tax considerations.

However, it involves careful planning and adherence to legal requirements. In the UK, businesses must notify HM Revenue and Customs (HMRC) of any changes to their financial year-end.

Navigating the financial year-end presents a range of challenges for businesses demanding careful attention and strategic planning. Here are some common challenges businesses we’ve worked with face. By addressing these challenges proactively, companies can navigate the financial year-end with greater ease.

Time Challenges

The financial year-end can be an incredibly busy period for companies, often leading to tight deadlines and increased workloads for finance teams. This rush can result in stress and oversight, complicating the closing process.

Data Accuracy

Ensuring data accuracy is crucial for producing reliable financial statements. Errors in data entry can have significant repercussions, potentially impacting decision-making and compliance.

Human Error

Human mistakes can occur in any part of the financial reporting process, from data entry to interpretation of financial information. These errors may lead to compliance issues and inaccurate reporting.

Tax Compliance

Managing tax obligations can be daunting during year-end. Companies must stay updated on changing regulations to ensure they meet their tax responsibilities, avoiding penalties and fines.

Regulatory Changes

Keeping up with regulatory changes can be challenging, requiring businesses to adapt their processes swiftly. This often involves additional training and adjustments to financial systems.

Managing Expenses

Accurate expense tracking is vital for financial clarity, yet it can be overlooked amid the hustle of year-end preparations. Implementing effective tracking methods can help maintain a clear view of financial health.

1. Set a close schedule early — allocate tasks, confirm deadlines, and make sure your team knows what's expected.
2. Gather your documentation — income statements, balance sheets, and cash flow records should all be in order before you begin.
3. Process expenses and bonuses before close — ensure all costs are logged in the correct tax year to avoid compliance issues.
4. Review, then plan ahead — use year-end data to assess performance, revisit pricing, and set goals for the year ahead.
