Use estimates for planning, not as the final filing position
Calculators can help with budgeting and understanding possible tax outcomes, but final liabilities depend on complete facts, current legislation and the correct tax treatment.
Keep the records behind the estimate
A useful tax estimate is only one part of the accounting process. The business still needs reliable records and supporting information for the figures used in accounts and returns.
Check the tax year and assumptions
Rates, thresholds and allowances can change. Before relying on any estimate, check which tax year and assumptions the calculator uses.
