Tax news in brief

Author: ICAEW Insights

Published: 30 Sep 2026

Highlights from the broader tax news for the week ending 30 September 2026, including HMRC's latest one-to-many campaign, focusing on consultants in the medical sector.

Underdeclared income in the medical sector

HMRC is writing to individuals who it believes may have failed to include consultancy income in their self assessment tax return, based on information received from healthcare providers. The letter sets a deadline for the individual to respond and explains the consequences for the individual of failing to take action. Agents will not receive copies of the letters. 

PAYE settlement agreements

ICAEW has responded (in ICAEW Representation 79/26) to the government’s call for evidence on how pay as you earn (PAYE) settlement agreements are used in practice. Based on member feedback, ICAEW believes the PAYE settlement agreement “remains an invaluable tool for UK employers, ensuring minor, irregular and impracticable benefits and expenses are subjected to tax and national insurance but allowing for the reasons why this cannot always be achieved on a real time basis”.

ICAEW Representation 79/26 will be published at 2026 Tax Representations | ICAEW in due course.

Corporation tax receipts surpass £100bn

HMRC has published corporation tax statistics for 2025/26. A key finding is that total receipts from all corporate taxes were £100.4bn in 2025/2026, an increase of £3.5 billion (4%) on the previous year. 

Scottish and Welsh rates of income tax

HMRC has published reports detailing the activity it carried out in its operation of Scottish and Welsh income tax in 2025/26. 

Using the new trader support service

HMRC has reminded businesses that all goods movements from 20 October 2026 must be submitted on the new trader support service (TSS) platform and has encouraged businesses to pre-enrol for the new platform. 

HMRC says that, from 1 October 2026, businesses currently using TSS will receive emails with instructions on how to pre-enrol for the new platform. Businesses will also receive instructions for accessing a test environment where they can familiarise themselves with how the platform works.
