Annual Allowance Income Calculator

AA IncomeCalc is an interactive app designed to help individuals estimate the total amount of tax relievable pension savings they are able to make into their pension schemes over a tax year.

Willis Towers Watson developed the AA IncomeCalc app in response to new rules from April 2016 and from April 2020 which link the amount of tax relievable pension savings an individual can build up each year, to their income. The introduction of these rules has led to greater complexity, resulting in many more individuals being impacted by the annual allowance (AA) than ever before.
