Farm Tax UK: IHT, CGT, SDLT and Income Tax on Farmland

Farm tax is not one tax. Four separate taxes decide what the land, the buildings and the rent cost you: inheritance tax when the farm passes to the next generation, capital gains tax when you sell part of it, stamp duty land tax when you buy more, and income tax on anything you let out. This guide covers those four, because those four are property taxes and property tax is what we do.

It does not cover the half of farming taxation that lives in your farm accounts, and the section near the end says who does. If the question you arrived with is whether farmers pay tax at all, the short answer is yes, on the same taxes as any other landowner, with one very large relief on the inheritance tax side and one useful rate quirk on the stamp duty side.

Will your family pay inheritance tax on the farm?

Only on the value above £2.5 million, and only at an effective 20%. From 6 April 2026 the first £2.5 million of your qualifying agricultural and business value passes free of inheritance tax, exactly as the whole of it used to. Above that allowance the relief halves, so half of the excess stays in the taxable estate and is charged at the ordinary 40% rate. A million pounds of qualifying value above the allowance therefore costs your family £200,000, not £400,000. If you are married or in a civil partnership, whatever part of the allowance the first of you to die has not used can be claimed by the survivor's executors, so the two of you can cover up to £5 million between you.

The number that decides your position is the qualifying value, not the market value of the whole place. That means the agricultural value of the land and buildings plus any genuine trading business, with cottages let to non-agricultural tenants, development hope value and any pure investment holdings stripped out, because those parts never qualified for the relief in the first place. Most farming families who work that number out discover they sit under the allowance and were bracing for a bill they will never receive, and the walk-through of how the allowance lands on a working farm is in inheritance tax on farms. Any guide still telling you the cap is £1 million was written at announcement stage and never updated after the legislation was passed.

The depth on the allowance sits elsewhere. The technical detail of the cap, including how lifetime gifts consume it, is in the April 2026 BPR and APR cap, and the wider picture across a whole rural holding is on our landed estates hub.

Do you pay capital gains tax when you sell farmland?

Yes. Farmland in the UK is not automatically exempt from capital gains tax, but reliefs can reduce or defer what you owe where the land was genuinely used in your farming trade. The rate is 18% on the part of the gain that fits inside your remaining basic rate band and 24% on everything above it, after your annual exempt amount of £3,000. Sell 60 acres for a £400,000 gain as a higher rate taxpayer and the sum is 24% of £397,000, which is £95,280.

Roll-over relief lets you defer the gain if you put the proceeds into replacement assets for the trade, which is how a farmer selling one block and buying another avoids paying tax on land that never left the business. It turns on the land being used in your farming trade, so acres you have let out for years fall outside it. Gift holdover can pass the gain to the person receiving the land instead of crystallising it on you, which matters where the farm is moving down a generation during your lifetime. It reaches further than roll-over does: agricultural land that qualifies for Agricultural Property Relief can be held over even where a tenant farms it rather than you.

The mistake we see most often is assuming Agricultural Property Relief carries over to a sale. It does not: that relief and Business Property Relief are inheritance tax reliefs, so a farm sold in your lifetime can produce a large capital gains tax bill on land that would have passed tax free on your death. Bare land is also not residential property, so a UK resident reports the gain through Self Assessment rather than the 60 day property service, while a sale that includes the farmhouse carries the 60 day deadline on its residential element where tax is due. The mechanics are in the deferral routes and the payment deadlines.

How much stamp duty do you pay on agricultural land?

You pay it, and you pay it at the non-residential rates, which is usually the cheapest news on this page. Agricultural land is not a dwelling and it is not the garden or grounds of one, so it sits outside the residential definition altogether. That puts your purchase on the non-residential table: nothing on the first £150,000, 2% on the slice from £150,000 to £250,000, and 5% on everything above £250,000. There is no additional dwellings surcharge on a non-residential purchase, however many farms you already own.

Put £900,000 of bare farmland through that table and you pay £0, then 2% of £100,000 which is £2,000, then 5% of £650,000 which is £32,500. Your bill is £34,500. Spend the identical £900,000 on a second house at residential rates with the 5% surcharge and you would pay £6,250 plus £8,750 plus £65,000, which is £80,000. The non-residential treatment is worth £45,500 to you on that one transaction, and it is the reason the classification question is worth getting right rather than accepting whatever the first draft return says.

Buying a working farm rather than bare acres makes the transaction mixed use, because a farmhouse is residential and the land around it is not. Mixed use puts the whole consideration through the same non-residential table, which is why farm purchases so rarely produce the eye-watering residential bills that buyers brace for. It is also the classification HMRC challenges hardest, and the challenges usually turn on whether the land is genuinely in commercial agricultural use or is really just a large garden. Our two guides on this are the tribunal tests for mixed use and how mixed-use classification actually works. One caveat on geography: land in Scotland is charged to Land and Buildings Transaction Tax and land in Wales to Land Transaction Tax, both with their own bands, so the figures above apply in England and Northern Ireland only.

Is rent from let farmland taxed as property income?

Yes, and this is the part of farming taxation that nobody writes down plainly. If you let land under a farm business tenancy, grant a grazing licence or rent out bare acres to a neighbouring farmer, that rent is property income rather than trading income. You add it to your other income, deduct the costs of earning it, and pay income tax on what is left. For 2026/27 that is the ordinary 20%, 40% and 45%.

From 6 April 2027 property income gets its own rates of 22%, 42% and 47% in England, Wales and Northern Ireland, two points above the equivalent general rates, while Scottish taxpayers stay on the Holyrood rates for this income. If a meaningful part of your farm income is rent rather than crops or livestock, that change is worth modelling now: on £40,000 of rental profit taxed at the basic rate, the two point rise costs you £800 a year. The general position on what you can deduct is in our complete guide to rental income tax.

Letting land instead of farming it changes the inheritance tax analysis as well as the income tax one, which is exactly why both belong on the same page. Agricultural Property Relief can still reach land that someone else occupies and farms, on a longer ownership test than the one that applies to land you farm yourself, but Business Property Relief does not reach passive rental at all. In other words, the decision to let rather than farm is a tax decision with consequences at both ends of your ownership, not just an operational one.

Which diversification income counts as property income?

The rent-shaped kind. If you have converted redundant buildings into offices, storage units, workshops or holiday cottages, or you receive rent from a solar array, a telecoms mast or a wayleave, that income is property income and it belongs in the same computation as your let acres. It is taxed the same way and moves to the 22%, 42% and 47% rates on the same date.

Two things follow that catch people out. Converted holiday cottages stopped being a special category on 6 April 2025 when the furnished holiday lettings rules were abolished, so a farm cottage on short lets is now an ordinary property business with none of the old advantages. And a diversified building generating rent is investment rather than trading for inheritance tax, so it does not qualify for Business Property Relief and can sit outside your qualifying value entirely. The detail on both is in commercial property tax for landlords and what the furnished holiday lettings abolition changed. If your holding mixes farmland with let property, the mixed estate allocation problem is the one to read, because the trading and agricultural parts compete for the same allowance.

Where your diversification is a genuine trade rather than a letting, such as a farm shop, a café or a livery yard with real services attached, the profit is trading profit and belongs with your farm accountant.

What this page does not cover, and who does

Plenty. A farming family needs advice that reaches well beyond the four property taxes above, and we would rather point you at the right person than write a thin version of their work.

• Herd basis. The livestock valuation election is a specialist farm-accounting decision and a farm accountant handles it.
• Farmers' averaging. Averaging your profits across two or five tax years is income tax work done on the trading accounts, again with a farm accountant.
• Basic Payment Scheme and the Sustainable Farming Incentive. Delinked payments, scheme entitlements and stewardship receipts are handled by your farm accountant or land agent.
• Agricultural tenancy law. Succession rights, rent reviews and notices to quit are a matter for a rural surveyor and a solicitor rather than a tax adviser.
• Farm accountancy generally. Property Tax Partners is a property tax specialist, not a farm accountancy practice, and we work alongside your existing accountant rather than replacing them.

Where should you start?

With the qualifying value on paper. Set it against £2.5 million, or £5 million if there are two of you, and you have the answer to the question most farming families are actually asking. Everything else on this page follows from where you sit against that figure.

Get in touch with the acreage, what is let and what you are thinking of buying or selling, and we will tell you which of the four taxes is actually your problem and which of them you can stop worrying about. If your farm accountant already handles the accounts side, so much the better, because that is the half we do not do.
