From April 2026, a number of important tax and business changes announced in the 2025 Budget are expected to start affecting businesses, investors, and employers across the UK. While some of these measures may appear technical at first glance, their practical impact could be significant.

Among the main changes is the reduction in Inheritance Tax relief for AIM shares. These holdings have long been used as part of estate planning, but from April 2026 they will no longer benefit from full Business Property Relief. Instead, only 50% relief will apply, which may reduce their attractiveness for those looking at long-term succession planning.

Employers will also need to prepare for higher staffing costs, with National Minimum Wage rates rising above inflation. At a time when many businesses are already facing pressure on margins, this could make workforce planning and budgeting even more important.

There are also changes to incorporation relief. Businesses moving into a company structure will no longer receive this relief automatically and will instead need to claim it through the self-assessment process. In addition, the £6 per week working-from-home allowance is due to be abolished, removing a simple and widely used tax deduction for many employees.

Commercial property owners and occupiers should also pay attention to the upcoming business rates revaluation, while businesses considering employee incentives may welcome the expansion of the EMI share option scheme.

Taken together, these changes could affect estate planning, payroll costs, business structure, and future growth decisions. The key message is simple: planning early matters. Waiting until the rules are already in force may limit your options and increase the risk of unnecessary costs.

If you are unsure how these changes may affect you, this is the right time to review your position. A proactive discussion can help you identify risks, explore opportunities, and put the right strategy in place before April 2026.
