Supporting Bookkeepers at Tax Year End: Deadlines, Recognition and Respect

Table of Contents

As we approach the end of the tax year, I want to take a moment to speak directly to our members and to the bookkeepers who are working tirelessly to support businesses through one of the most demanding periods in the financial calendar.

This time of year brings with it heightened pressure: multiple deadlines, increased client queries and the responsibility of ensuring accuracy when it matters most. On behalf of the Institute of Accountants and Bookkeepers (IAB), I want to acknowledge the professionalism, resilience and dedication bookkeepers consistently demonstrate—and to say thank you.

The Reality of Tax Year End Pressures

Bookkeepers are often the steady hand guiding clients through complex obligations, changing regulations and important financial decisions. As the tax year draws to a close, the volume and importance of those responsibilities intensify.

Clients rely on you not only for technical accuracy, but for reassurance and clarity. Whether you are supporting sole traders, limited companies or growing businesses, your role is fundamental to keeping the wheels of the economy turning.

Key Tax Payment Deadlines to Be Aware Of

As part of that responsibility, keeping clients informed of critical deadlines is essential. The most significant tax payment dates include:

  • 31 January

    • Balancing payment for the previous tax year
    • First payment on account for the current tax year

  • 31 July

    • Second payment on account for the current tax year

These dates are well known, but they remain a source of stress for many clients, particularly those managing cash flow or navigating self-assessment for the first time. Your guidance at these points is invaluable to clients.

Other Important Compliance Deadlines

In addition to tax payments, bookkeepers play a crucial role in helping clients stay compliant with wider statutory obligations, including:

  • Confirmation Statement

    • Due annually, within 14 days of either the company’s incorporation date or the date of the last confirmation statement

  • Annual Accounts

    • Due 9 months after the company’s financial year end

Missing these deadlines can have serious consequences for businesses, and your diligence in monitoring and managing them makes a tangible difference.

Preparing for the Future: Making Tax Digital

The regulatory landscape continues to evolve, and bookkeepers are at the forefront of helping clients adapt. One of the most significant upcoming changes is Making Tax Digital (MTD) for Income Tax.

From April 2026, businesses with an annual income of over £50,000 will be required to submit quarterly updates under MTD for Income Tax. While this change is still on the horizon, preparation and client education are already well underway—and bookkeepers are central to making this transition successful.

Supporting Wellbeing as Well as Compliance

At IAB, we recognise that professionalism is not just about meeting deadlines—it is also about sustainability. Long hours and constant pressure should not be seen as the norm.

As this busy period continues, I encourage bookkeepers to:

  • Set realistic expectations with clients
  • Lean on professional networks and peer support
  • Recognise the value of their expertise and time

Looking after your own wellbeing is essential to maintaining high standards and a thriving practice.

IAB’s Ongoing Commitment

Our mission at IAB is to support, promote and represent bookkeepers and accountants at every stage of their careers. Through qualifications, continued professional development, technical guidance and a strong professional community, we remain committed to helping bookkeepers feel confident, valued and prepared—especially during peak periods like tax year end.

A Final Word of Thanks

The end of the tax year is both a culmination of months of work and a gateway to the year ahead. To every bookkeeper navigating deadlines, supporting anxious clients and upholding professional standards under pressure: your work matters, and it does not go unnoticed.

On behalf of everyone at IAB, thank you for the essential role you play.
