Need the figures checked against your records?
The calculators are a starting point. In an initial consultation we can check the assumptions against your accounts, rental records or contract terms and put the result in writing.
Using the calculators
What the figures can and cannot tell you
Each calculator uses the published UK tax rates and thresholds for the year shown on the page. They are useful for checking broad positions: director pay, Corporation Tax bands, VAT scheme choice, Section 24 on rental income, Capital Gains Tax and whether incorporation is worth looking at properly.
The result still depends on the records behind it. Associated companies, pension payments, student loans, spouse shareholdings, losses, finance costs and timing can all change the answer. Treat the output as a planning estimate, then check it against your bookkeeping, payroll records, rental statements or contract terms before acting on it.
If a result shows a meaningful tax movement, the next step is usually a written forecast. That is where we check the assumptions, compare the options and set out what can still be changed before the relevant filing or payment deadline.
