Agricultural property sits at the intersection of several tax regimes. For CGT purposes, the rules that apply depend on whether the land is in active agricultural use, whether there is a farmhouse, and whether the sale involves development potential. This is a complex area — what follows is an overview of the main principles.
Agricultural land: the basic CGT position
Agricultural land is not residential property. This means:
- The 60-day CGT return for UK residential property disposals does not apply
- CGT on agricultural land disposals is reported on the annual Self-Assessment return
- Residential CGT rates (18% and 24%) do not apply — the standard CGT rates of 10% and 20% apply instead
This is a significant difference from residential buy-to-let. Farmers and landowners selling agricultural land generally pay lower CGT rates and have a longer filing window.
Rollover relief for working farmers
Where agricultural land is sold and the proceeds are reinvested in other qualifying business assets (including other agricultural land, farming equipment, or commercial property used in the farming business), rollover relief under section 152 TCGA 1992 allows the gain to be deferred.
The conditions are:
- The land must have been used in the trade of farming
- New qualifying assets must be purchased within three years after (or one year before) the disposal
- The relief defers the gain into the base cost of the new asset — it is not an exemption, merely a deferral
Rollover relief is one of the most valuable CGT reliefs available to farmers and is routinely used in farm restructuring and succession planning.
Business Asset Disposal Relief
Farmers who sell farmland as part of a genuine trade of farming may be eligible for Business Asset Disposal Relief (formerly Entrepreneurs' Relief), giving an effective CGT rate of 10% on qualifying gains up to the lifetime limit. The land must have been used in a business and held for at least two years.
BADR is not available on investment land — it requires the land to have been used in a trade. A farmer letting land on agricultural tenancies is typically not trading for BADR purposes.
The farmhouse: CGT and PRR
A farmhouse occupied by the farmer as their main home qualifies for Private Residence Relief in the same way as any other main home. If the farmer has lived in the farmhouse throughout ownership and the farmhouse is sold, PRR covers the gain on the residential element.
Where a farmhouse is sold as part of a wider farm disposal (land and farmhouse together), it is necessary to apportion the gain between the residential element (PRR may apply) and the agricultural land element (commercial CGT rates apply, rollover may be available).
The HMRC view has historically been that the farmhouse should be valued at its residential market value, not at an agricultural discount, for CGT apportionment purposes.
Development land uplift
If agricultural land is sold with planning permission or development potential, the proceeds will reflect the development value. This can create a very large gain relative to the agricultural value of the land.
The uplift from agricultural to development value is a capital gain. Depending on the amount, this could be a life-changing transaction. Planning ahead — including whether to sell with or without planning permission, and how to structure the transaction — can make a significant difference to the tax outcome.
Where overage clauses are involved (the seller retains rights to additional payments if development occurs), deferred consideration CGT issues also arise.
31 March 1982 rebasing
For agricultural land acquired before 31 March 1982, the base cost is the market value at 31 March 1982 rather than the original acquisition price. This often significantly increases the base cost and reduces the gain. Agricultural land values in 1982 may be much lower than current values, so the rebasing can produce a much larger gain than for a residential property. Agricultural land value indices can help establish 1982 values, but specialist agricultural valuation evidence is usually required for significant holdings.
Where to get advice
Agricultural CGT is a specialist area that intersects with agricultural property relief for IHT, business property relief, succession planning, and rural estate structures. If you are selling agricultural land, a specialist agricultural accountant or tax adviser is recommended.
If the disposal includes a residential farmhouse and PRR applies to part of the gain, and the 60-day CGT return obligation arises on the residential element, LetsFile can handle the residential component. The Chartered Accountant/Chartered Tax Advisor coordinates with your agricultural adviser on the apportionment.
