Notes, assumptions and tax tables

There are no company tax changes from the previous tax year. Although, importantly, when you work out your personal taxes, the basic and higher rates of dividend tax have increased by 2p each for 2026/27. Try our dividend calculator next.

• Corporation Tax rates increased in April 2023. Find out more here.
• We have ignored the Employment Allowance, which refunds Employers’ NICs up to £10,500 each calendar year. For most small companies (such as contractors), the impact of this incentive is likely to be minimal if you and/or your employees are paid low salaries.
• To find out the most tax-efficient director’s salary for 2026/27, read this key article.
• We have assumed that any billable work included within the ‘Annual Revenue’ figure does not fall within the scope of the IR35 rules.
• All calculations have been verified by our ACA-qualified accountant. Please talk to your accountant if you have any tax-related questions.
