New Tax Year Brings a £2.5m Inheritance Tax Reset — and a Test for Family Farms

The new tax year opens with a rule change that many family farms and closely held businesses have been watching with unease. From 6 April, the new tax year brings a revised inheritance tax regime for inherited farms and family businesses worth £2. 5 million or more. Accountants say the shift could force owners to rethink succession much earlier, especially where business value is tied up in land and assets rather than ready cash. For some families, the question is no longer whether to plan, but how quickly they can do so.

Why the new tax year matters now

The immediate issue is simple: the first £2. 5 million of combined agricultural and business property will continue to receive 100% relief from inheritance tax, while amounts above that threshold will receive 50% relief. Each person will have a £2. 5 million allowance. That change arrives after months of pressure from campaigners and MPs representing rural areas, following an earlier government plan announced in October 2024 that triggered protests around the UK. The new tax year therefore marks not just a calendar shift, but a policy shift with direct consequences for succession planning.

Accountants say the practical effect will vary, but the burden is likely to fall hardest on businesses that are asset-rich but cash-poor. That is where the new tax year becomes more than a tax date: it becomes a test of whether owners can reorganize holdings, timing, and inheritance plans before liabilities appear. The government has said the higher threshold should significantly reduce the number of farms and business owners facing larger bills, with only the largest estates affected. Yet the concern within the sector remains that even a narrowed rule can still bite hard at the point of transfer.

What lies beneath the headline change

The deeper issue is the tension between valuation and liquidity. Under the revised regime, land and business assets can create exposure even where the family has little spare cash. Elsa Littlewood, a private client partner at accountancy and business advisory firm BDO, called the start of the regime “a watershed moment for the farming and family business community. ” She said the policy is “a significant departure from the previous regime” and warned it will “pose significant challenges for those businesses in scope. ”

Littlewood added that many owners will need to devote far more time and attention to succession planning earlier in life to improve the chance that the business can be transferred efficiently and remain viable over the long term. She also said the new regime will be particularly challenging for farm businesses that may be asset-rich but cash-poor, adding that in some circumstances beneficiaries may have to sell land or assets to pay inheritance tax liabilities. That is the central tension behind the new tax year change: a business can look strong on paper while still struggling to absorb a tax bill.

The policy also reflects a broader political and rural debate that has been building since the original 2024 announcement. The increase in the threshold from £1 million to £2. 5 million was welcomed by many in the sector, but the tax changes remain controversial because they still alter long-standing protections. For families who have structured ownership around the expectation of full relief, the new tax year means revisiting assumptions that have shaped land use and succession for decades.

Expert warnings and sector pressure

At the center of the debate is the practical work of transfer, not just the theory of reform. The new tax year gives families little room for complacency, particularly where multiple assets, partnerships, or business interests are involved. The need for accurate valuations of land, buildings, crops, stock, and machinery is rising as owners prepare for gifting or succession events. That demand alone signals how much administrative strain the change may create before any tax bill is even due.

There is also an unevenness in how the policy lands across the countryside. Private family farms are expected to feel the burden most sharply, while foreign landowners tied to their own domiciles, charities, and publicly listed companies are said to be largely unaffected. That contrast has intensified concerns about fairness at a time when rural businesses are already managing uncertainty and regulatory pressure. In that sense, the new tax year is not only about revenue; it is about which types of ownership the system rewards or penalizes.

Regional and wider business impact

Beyond farming, the change reaches family businesses more broadly, making succession a central boardroom issue for owners whose wealth is embedded in productive assets. The government has said the higher threshold will significantly cut the number of affected estates, but the market response has already included slower land sales and more restructuring as businesses wait for clarity. That suggests the new tax year may reshape behavior before it fully reshapes tax receipts.

For Scotland’s rural economy, the issue is compounded by other legislative change, including the Land Reform (Scotland) Bill, which is expected to influence estate management and market activity over time. The cumulative burden matters: tax reform, land reform, and succession pressure now move together, forcing owners to balance capital investment, ownership structures, and family continuity in one planning cycle. The result is a more uncertain environment for families trying to hold businesses together across generations.

The new tax year has therefore become a stress test for policy, fairness, and survival. If the first £2. 5 million is protected, what happens to the businesses built just beyond it?
