How to use the calculator

Simply fill in the yellow boxes, as indicated, and the calculator will work out how much post-tax profit is available to distribute as dividends, following a deduction for Corporation Tax (plus any expenses incurred during the tax year).

Assumptions used in this calculator

• Corporation Tax has been applied at the prevailing rate of 19% (2017-18 tax year).
• We have ignored the Employment Allowance, which refunds Employers’ NICs up to £3,000 each calendar year. For the majority of 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.
• 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.
