Entrepreneurial Tax Relief Is Quietly Changing — And Founders Are Paying Closer Attention

Every spring, a specific discussion takes place in the offices of accountants in London, Manchester, Dublin, and Cork. “I think I’m ready to sell,” the founder, who is frequently in their fifties but occasionally younger, says as they enter. Usually, what comes next is more of a chilly shower than a celebration. The relief that was supposed to come after years of late nights, mortgaged homes, and unpaid bills has subtly evolved. The seller is not as favored by the numbers as they once were.

The majority of people in the UK and Ireland support the existence of entrepreneurial tax relief. Establishing a business is challenging. It is more difficult to risk personal funds. Even the skeptics find it somewhat harsh to tax every pound of gain at standard capital gains rates when someone eventually leaves. The relief, known as Entrepreneur Relief in Ireland and Business Asset Disposal Relief in the UK, was intended to lessen that impact. The sale is not tax-free as a result. It lessens the pain.

Rates for the UK version, which was renamed from the previous “Entrepreneurs’ Relief” name, have been steadily rising. Qualifying gains were subject to a 10% tax until April 2025. The rate increased to 14% after that date. It increases once more to 18% on April 6, 2026. The previous lifetime cap of £10 million has been drastically reduced to £1 million of qualifying gains. The requirements for ownership—two years as a partner, sole proprietor, or five percent shareholder—remain unchanged. In less than two years, the relief for anyone doing the math on a long-planned exit has decreased significantly.

Although Ireland’s version has a slightly different structure, it still seems more founder-friendly on paper. When you sell shares in a company you have owned for at least three of the previous five years, you will be subject to a 10 percent rate on the first €1 million of qualifying gains, as long as you were also a director or employee and spent more than half of your working hours in a management or technical role. There is a real difference in that rate. At the standard 33 percent CGT rate, a simple sale with a €9 million gain would result in a €3 million tax bill. The bill is reduced by about €460,000 when Entrepreneur Relief is applied. This is real money that most founders would prefer to invest in a house, a pension, or, to be honest, a sailboat.

Speaking with advisors at companies like Saffery, Grant Thornton, and the smaller planning boutiques, it seems like too many founders still view this relief as a checkbox. It isn’t. The math is altered by the regulations governing what constitutes a trading company, the structuring implications of holding companies, and the complications brought about by the issuance of shares through an EMI scheme in the UK. The clock may be reset for a sole proprietor who combined operations into a partnership three years prior to sale. If a shareholder chooses to be treated as having sold and re-bought their shares at the dilution moment, they may still be eligible even if their stake dropped below five percent due to the company issuing new shares. You don’t want to learn these details at the closing table for the first time.

During cycles of fiscal tightening, it’s difficult to ignore how frequently governments covertly reshape reliefs like this. The changes in UK rates in 2025 and 2026 are not accidental. They are a continuous adjustment of the state’s desired compensation for founders in relation to the amount of money it must raise. The planning window is smaller than it appears for anyone intending to leave within the next three years. Establishing the proper structure a year or two ahead of time is often more important than the sale price.
