Running a business means juggling a hundred different priorities, and tax rarely gets the attention it deserves until a deadline forces the issue. The problem with that approach is it leaves gaps, and those gaps often mean your business is paying more tax than it needs to.
At Taylor Associates, we regularly sit down with business owners who are surprised to learn they have been overpaying. Not because they have done anything wrong, but because nobody has taken the time to review their position properly. The good news is that overpaid tax can almost always be claimed back. But you need to know where to look, and in some cases you need to act before the window closes.
Where businesses lose money on tax
There is no single cause, but these are the situations we see most often with the businesses we work with.
Unclaimed allowances and deductions. This is by far the most common issue. Business owners miss legitimate expenses that would reduce their taxable profit: office costs, business mileage, insurance, training courses, professional subscriptions, even a proportion of home utility bills for those who work from home. If it is not recorded and claimed, it is money left on the table.
Capital allowances overlooked. When your business invests in equipment, vehicles, machinery or technology, capital allowances let you deduct some or all of the cost from your taxable profits. With the Annual Investment Allowance currently set at one million pounds, many small and medium businesses can write off the full cost of qualifying purchases in the year they are made. Despite this, we regularly meet business owners who have not claimed what they are entitled to.
Inefficient pay structures. For limited company directors, how you take money out of the business has a direct impact on your tax bill. The balance between salary, dividends and pension contributions needs to be reviewed regularly, especially now that dividend tax rates have increased. Getting this split wrong can cost thousands over the course of a year.
VAT errors. Businesses sometimes overpay VAT simply by not reclaiming everything they are entitled to, or by using the wrong VAT scheme. Others miss the point at which the flat rate scheme stops being beneficial. A quick review of your VAT position can often uncover money that should have stayed in the business.
Payments on account set too high. If your business profits have dropped compared to the previous year, your payments on account to HMRC could be based on outdated figures. You are entitled to apply to reduce them, but many business owners do not realise this and end up overpaying, only to wait months for a refund after filing their return.
How to check if your business is overpaying
Review your expenses. Go through your records and ask whether every allowable cost is being captured. Our accountancy team regularly identifies missed deductions during year-end reviews that save clients hundreds, and sometimes thousands, of pounds.
Check your structure. Are you operating as a sole trader when a limited company would be more tax efficient? Or vice versa? As your business grows and your circumstances change, the structure that made sense at the start may no longer be the best fit. A periodic review ensures your setup is still working in your favour.
Look at how you pay yourself. If you are a company director, when did you last review your salary and dividend split? With dividend tax rates rising from April 2026 and the personal allowance still frozen, what worked two years ago may now be costing you more than it should.
Audit your VAT. Check that you are reclaiming input VAT on all qualifying purchases, and that your current scheme is still the most beneficial. If your turnover has changed significantly, it is worth revisiting.
How to claim overpaid tax back
For sole traders and partnerships, overpayments are usually corrected through your self-assessment tax return. Getting that return right first time matters. Errors can delay a refund, and inconsistencies can attract unwanted attention from HMRC. If that does happen, our tax investigation team is on hand to deal with HMRC directly on your behalf.
For limited companies, overpaid corporation tax can be reclaimed by filing an amended return. VAT overpayments can be corrected through your next VAT return if the error is below a certain threshold, or by contacting HMRC directly for larger amounts.
It is also worth knowing that you can amend a tax return for up to twelve months after the filing deadline, and in some cases make claims going back four years. So even if something has been missed in previous years, there may still be time to put it right.
Do not wait until year end
The biggest mistake we see business owners make is treating tax as a once-a-year problem. By the time you sit down to file your return, it is usually too late to make the changes that could have reduced your bill.
Tax planning works best when it happens throughout the year. Regular reviews of your income, expenses and structure keep you in control and help you avoid surprises. Our bookkeeping services support this by keeping your records accurate and up to date, so when it is time to file, everything is already in order.
