Agricultural Accountants in Carmarthenshire
Written and reviewed by the Agricultural Accountants editorial team. Last reviewed 27 July 2026.
Carmarthenshire is Wales's leading dairy county, mild and wet west-Wales grass carrying dairy herds with beef and sheep throughout. It is grass-based livestock farming, and it sits under the Welsh farm-support system, which is changing on its own timetable, not England's.
So a Carmarthenshire farm has the usual dairy tax questions plus a different, and newer, subsidy transition.
Welsh Dairy and the Herd Basis
A Welsh dairy or breeding herd can go on the herd basis just as an English one can, keeping the herd out of the trading account, and averaging smooths the milk-price swings. These reliefs are UK-wide and work the same in Wales, as our guide to averaging and the herd basis explains.
Income tax and inheritance tax are not devolved, so the 2026 reliefs at the current £2.5 million position apply to a Welsh farm exactly as to an English one.
The Welsh Sustainable Farming Scheme
Farm support is devolved, and Wales is replacing its Basic Payment Scheme with the Sustainable Farming Scheme from January 2026, with the old payments phased out to 2029. That is a different timetable and a different scheme from England's delinked payments, but the tax treatment is the same: the payments are taxable as farming income.
A Welsh farm therefore needs its subsidy handled on the Welsh rules while its tax is handled on the UK-wide rules, which is set out in our guide to farm subsidies.
