The available evidence does not provide Scotland-specific data on the share of income tax paid by the top 10% of Scottish taxpayers. UK-wide figures from the House of Commons Library and IFS show the top 10% of UK taxpayers contribute around 59–60% of income tax receipts — a higher share than the 50% claimed. The IFS note on Scottish tax policy confirms the top decile pays more under the Scottish system than under the English/Welsh system, but does not give a percentage share of total Scottish income tax. The claim's 50% figure is lower than the UK-wide equivalent (59–60%), making it potentially an understatement, but since no Scotland-specific breakdown of the top 10%'s share is provided in the evidence, the claim cannot be fully verified or refuted for Scotland specifically. It is imprecise because the UK-wide data suggests the true figure is higher than 50%.","sources":[{"url":"https://commonslibrary.parliament.uk/research-briefings/cbp-9186/","ente":"House of Commons Library","titolo":"Income tax: freezing the personal allowance and the higher rate threshold","estratto":"In 2024/25 the top 10% of income taxpayers contributed around 59% of income tax receipts (UK-wide figure, not Scotland-specific)."},{"url":"https://ifs.org.uk/taxlab/taxlab-taxes-explained/income-tax-explained","ente":"Institute for Fiscal Studies (IFS)","titolo":"Income tax explained","estratto":"The top 10% of taxpayers paid 60% of all income tax in 2023–24 (UK-wide figure, not Scotland-specific)."},{"url":"https://ifs.org.uk/publications/scottish-governments-record-tax-and-benefit-policy-0","ente":"Institute for Fiscal Studies (IFS)","titolo":"The Scottish Government's record on tax and benefit policy","estratto":"It is at the top of the income distribution where income tax is higher, averaging just over £4,000 a year more per year than under the English and Welsh system for the highest-income tenth (decile) of households."}],"issued_at":"2026-07-01T06:13:13+00:00"},"signature_b64":"2svCJ08g7b2hMAEZV/v7VXF67xXKNW2i0K/GwTr1TtUcS5I1EdLO08EhxmqpcP9FjIVS+2kwv2GW5cvZC852Aw==","public_key_hex":"1719e2638a2cc0ec8d552d71dca52197f934e0a66b17e6364f1eed7a1d428e01","note":"Verifica offline: ed25519_verify(public_key, base64decode(signature_b64), canonical_json(payload))."}
