How the Autumn Budget dividend and threshold changes hit your income
Budget announcements tend to get covered as one-off news stories, with generic calculators built for a single fiscal event and then abandoned. For contractors, though, the effects compound: the two-percentage-point dividend tax rise from 6 April 2026 (basic rate 8.75% to 10.75%, higher rate 33.75% to 35.75%), income tax and National Insurance thresholds still frozen and due to stay that way until 2030/31, and the April 2026 umbrella joint-and-several-liability rules all land in the same tax year and interact with each other.
This calculator quantifies the personal £-per-year impact of those changes on your specific income, rather than the employee-only headline figures most Budget-day coverage focuses on — showing the dividend tax rise applied to your actual salary/dividend split, the ongoing cost of frozen thresholds compared with an inflation-linked alternative, and, where relevant, how the umbrella liability changes affect which umbrella providers are worth using.
What this calculator quantifies
- The direct £ cost of the 2-percentage-point dividend tax rise (10.75%/35.75%, from 8.75%/33.75%) on your actual dividend income for 2026/27
- The cumulative cost of frozen income tax and National Insurance thresholds compared with a scenario where they'd risen with inflation, given the freeze is set to continue to 2030/31
- Contractor-specific impacts most Budget coverage skips entirely, including the April 2026 umbrella joint-and-several-liability changes
- A single evergreen page updated at each fiscal event, rather than a new tool built and abandoned every Budget
