Frequently asked questions
How much is Council Tax in Carmarthenshire?
The 2026/27 Band D rate in Carmarthenshire is £2,351 a year inclusive of all precepts. Band D is the statutory reference point: every other band is a fixed fraction of it, so bills run from £1,567 at Band A to £5,486 at Band I.
Is Carmarthenshire above or below the Wales average?
Carmarthenshire is £68 above the Wales average Band D of £2,283, a difference of 3.0%. The gap is driven by the billing authority's own charge plus the police, fire and (where applicable) county and parish precepts that appear on the same bill.
What if I live alone?
A single adult household gets a 25% Single Person Discount. On Band D in Carmarthenshire that takes the bill from £2,351 to £1,763 a year, or £176 a month over ten instalments. The discount is not automatic - you have to claim it from the council, and it applies to the property, not the person.
Which band is my property in?
Bands are set by the Valuation Office Agency in England and Wales, and by Scottish Assessors in Scotland, against property values on a fixed valuation date: 1 April 1991 in England and Scotland, 1 April 2003 in Wales. That is why a new-build is banded by what it would have been worth on that date rather than today. You can look your band up free on the gov.uk Council Tax band checker.
Can I pay over 12 months?
Yes. Billing authorities in England and Wales must offer 12 instalments on request, and Scottish councils generally do the same. The default is ten instalments running April to January, which makes each payment larger but clears the bill before the new year. The annual total is identical either way.
