How Welsh Income Tax Works

Income Tax in Wales is partially devolved. Wales sets a portion of each tax band (currently 10p), while the UK Government sets the remaining amount. This means that the overall tax bands match those used in England and Northern Ireland.

  • Tax code begins with “C” for Welsh taxpayers.
  • Personal Allowance remains the same across the UK.
  • National Insurance is not devolved — same for all UK nations.
  • Tax applies to salary, pensions and rental income.
  • Dividend and savings income use UK-wide tax rules.
