Every year, we speak to business owners who know the Tax Year End is approaching but aren’t confident they’re focusing on the right things before it arrives.

The issue isn’t effort. It’s clarity.

This checklist is designed to help you focus on the decisions that genuinely move the needle and avoid the common mistakes we see time and time again.

Why the Tax Year End Is Still One of the Biggest Missed Opportunities

The tax year end is a hard deadline. Once it passes, planning turns into history.

Allowances reset on 6 April. Dividend rates are set to rise from April 2026. The tax rates on renal income are increasing. Income tax thresholds remain frozen, quietly pulling more people into higher tax bands.

The result? Business owners paying more tax than expected, not because they’ve done anything wrong, but because they didn’t pause to review the timing of their decisions.

The Tax Year-End Checklist

1. Is Your Director’s Salary Actually Doing Its Job?

☐ Salary reviewed against the personal allowance
☐ National Insurance position checked
☐ Payroll adjusted if needed

Beansprout view:
This is the foundation and it’s often set once and forgotten. We regularly see directors either underusing their allowance or paying unnecessary National Insurance because no one revisited the numbers. A small adjustment before 5 April can quietly improve tax efficiency without adding complexity.

Common mistake: Assuming last year’s salary is still the “right” answer.

2. Have You Used the Dividend Allowance — Properly?

☐ £500 allowance reviewed
☐ Profits available
☐ Paperwork in place

Beansprout view:
The allowance may be modest, but ignoring it is the same as choosing to pay tax when you don’t need to.

3. Are Your Dividends Falling Into the Right Tax Band?

☐ Total income reviewed (including rental income)
☐ Unused basic rate band identified
☐ Dividend timing considered

Beansprout view:
This is where opportunity is often overlooked. If you have unused basic rate tax band, then it might be worth paying an additional dividend before 5 April (subject to available profits) ahead of the dividend tax rate increases. Timing can really matter here.

Example:
A £10,000 dividend taxed at 8.75% results in £875 of tax.
After the rate increase, that same dividend would cost £1,075 — an extra £200 for no additional benefit.

And don’t forget, Dividends are taxed based on total income, not just what comes from the company. Rental income often pushes directors into higher tax bands without them realising.

Make sure you know which band your dividends are falling into and that you understand your liability.

Common mistake:
Taking dividends “when cash is there” rather than when tax bands make sense.

4. Are You Overlooking Pension Contributions?

☐ Employer pension contributions reviewed
☐ Annual allowance considered
☐ Cash flow assessed

Beansprout view:
Pensions remain one of the most powerful and underused tools available to owner-managed businesses looking to reduce tax liabilities. Employer contributions reduce company profits, save corporation tax and avoid income tax and National Insurance altogether.  Personal contributions can extend your basic rate tax band, putting more money back in your pocket. Yet many directors dismiss pensions as something to “deal with later”.

Common mistake:
Waiting until personal income is high, rather than using the company to contribute tax-efficiently along the way.

5. Have You Used Your ISA Allowance Intentionally?

☐ £20,000 allowance reviewed
☐ Funds invested or consciously retained
☐ Personal savings aligned with business income

Beansprout view:
ISAs aren’t just for passive investors. For business owners, they’re a flexible way to build personal wealth once profits leave the company.

Common mistake:
Extracting funds without a clear plan for what happens to them next.

6. Do You Actually Know Your Numbers Right Now?

☐ Current profits understood
☐ Cash reserves reviewed
☐ Future tax bills accounted for

Beansprout view:
Tax planning without up-to-date figures is guesswork. We see too many decisions made on instinct rather than information and those decisions usually cost more in the long run.

Common mistake:
Assuming “it’ll be fine” without checking.

Our Final Advice

Good tax planning works best when it’s done in advance, not rushed at the last minute. The most effective strategies are built over time and aligned with your wider business and personal goals.

That said, the Tax Year End is still a valuable checkpoint. It’s rarely the right time for complex schemes, but it is the ideal moment to review what’s already in place and make sure no allowances have been missed.

You don’t need to do everything on this checklist — but you do need to understand why you’re taking each step. Once 5 April passes, options are limited. Even a short review now can make a real difference to both your tax bill and how confidently you enter the new tax year.
