Check if you have to pay tax on your pension.
HMRC has released an online tool to help individuals estimate the amount of Income Tax they may owe on their pension for the current tax year. This tool is intended for those who started receiving their State Pension after 5 April 2010 and requires details of all pension income and other taxable earnings. Users can access the calculator on the GOV.UK website to determine their tax liability based on the standard Personal Allowance.
