Key checks for business owners reviewing inheritance tax and succession plans

Running a business takes years of focus, and it is easy to put off the question of what happens next. Yet for many owners, the most significant financial event their estate will face is the inheritance tax payable on the business itself. Getting a succession plan right is not just about passing on control. It is about making sure the people who take over are not burdened by a tax bill that could force a sale or break up the business.

A good review starts with understanding how the business is treated for inheritance tax purposes. The rules offer generous reliefs, but they come with conditions that need to be met and maintained. A checklist approach can help owners work through the key points without missing something that could prove expensive later.

Check the ownership structure and what it means for relief

The first thing to look at is how the business is owned. A sole trader, a partnership, a limited company and a shareholder in a family trading company each face different rules. Business property relief (BPR) is the main relief available on most business assets, but the type of ownership affects how the relief applies and at what rate.

For a sole trader or partner, the whole of the business interest can qualify for 100% relief after it has been owned for at least two years. For a shareholder in a company, the shares can also qualify, but only if the business is a trading business and not one whose main activity is investment. That distinction matters. A company that holds property or investments rather than carrying on a commercial activity may not qualify at all.

Many businesses evolve over time, and a company that once traded may gradually hold more investment property or cash. It is worth checking that the current mix of activities still counts as trading in the eyes of HMRC. If the non-trading element grows too large, the relief can be reduced or lost entirely.

Confirm the qualifying period is met and will continue

Business property relief requires the owner to have held the business or shares for at least two years before the transfer. That sounds straightforward, but the clock can reset if the business is reorganised or if shares are swapped during a restructuring. A demerger, a share-for-share exchange or a change of business structure can break the qualifying period, and the new holding may have to start again from scratch.

For owners who have held the business for many years, this is usually not a problem. But for those who have recently restructured or brought in new shareholders, it is a detail worth checking. If the owner dies within the two-year period after such a change, the relief may not be available.

There is also a trap for owners who are considering gifting the business during their lifetime. If they give away the business but continue to benefit from it, perhaps by drawing a salary or using assets, HMRC may treat the gift as having a reservation of benefit. That can undo the relief and bring the full value back into the estate.

Look at how the succession plan will work in practice

A succession plan is not just a tax document. It needs to describe who gets what and how they will manage the business afterwards. If the plan leaves the business to one child who is already working in it, and other assets to another child who is not, the inheritance tax calculation needs to reflect that the business qualifies for relief while the other assets do not.

Where the business is left to a spouse or civil partner, the transfer is exempt from inheritance tax anyway. But if the spouse then dies soon after, the relief may be lost because the spouse did not own the business for the two-year qualifying period. Some plans use a will trust to preserve the relief, but that adds complexity and requires careful drafting.

Another common issue is what happens to the business if the owner dies and the successor is not ready to take over. A temporary manager or a sale may be needed, but a forced sale can destroy the value that the relief was meant to protect. A good plan includes a transition period that gives the successor time to prepare.

Review life cover and how it interacts with the plan

Many business owners take out life assurance to cover a potential inheritance tax liability. The policy can be written into trust so that the payout sits outside the estate and is not taxed again. But the policy needs to be reviewed whenever the succession plan changes. If the business value rises or falls, the cover may no longer match the likely tax bill.

It is also worth checking who pays the premiums and whether that payment could be treated as a gift for inheritance tax purposes. If the premiums are paid by the business and the policy is in the owner's name, there may be a benefit in kind that creates an unexpected tax charge. A clean arrangement is one where the policy is owned by a trust and the premiums are paid by the owner as a straightforward gift that falls within the annual exemption.

Consider the effect of business assets that are not trading assets

Not everything in the business balance sheet qualifies for relief. Surplus cash that is not needed for the trade, investment properties, and personal assets held through the business may not qualify. If the business owns a building that is let to a third party rather than used for the trade, that part may be treated as an investment and subject to inheritance tax at the full rate.

This is a common problem for family companies that own the trading premises. If the building is used by the trading company itself, it should qualify. But if the building is owned by a separate property company and let to the trading company, the position is more complex. The property company may not qualify as a trading business, and the shares in it may not get relief.

A review of the balance sheet with this in mind can help identify assets that should be extracted or restructured before the owner's death. But any restructuring needs to be done carefully to avoid triggering a capital gains tax charge or breaking the qualifying period for relief.

Work through the plan with someone who knows the rules

Inheritance tax planning for business owners is not a one-size-fits-all exercise. The rules around business property relief and agricultural property relief have been tightened in recent years, and HMRC looks closely at claims where the business has a significant investment element. A plan that worked five years ago may no longer be effective.

Jones & Co provides personalised inheritance tax planning to assess estate exposure, reduce avoidable tax and help families pass on wealth clearly and efficiently. A review of the succession plan with a firm that understands both the tax rules and the realities of running a business can make the difference between a plan that works and one that creates problems for the next generation.

For most business owners, the goal is not to avoid tax at all costs. It is to make sure that when the time comes, the business can pass to the people who will run it next without a tax bill that forces difficult choices. A checklist approach helps, but the real value comes from working through the details with someone who can see the full picture. Jones & Co can help owners review their current plan and make sure it still fits the business as it is today, not as it was when the plan was first written.

A good succession plan is not a document that sits in a drawer. It is a living arrangement that should be revisited whenever the business changes, the family changes, or the tax rules change. For owners who want to protect the business they have built, a regular review is the most practical step they can take.
