🔍 Accuracy Standards
Our calculation algorithms undergo rigorous unit testing at the start of every tax year. We do not use simplified estimate roundings; instead, our calculations model complex, real-life rules such as the exact taper of the personal allowance between £100,000 and £125,140, regional Scottish tax bands, and company car carbon emissions (CO2) scale rates.
