To see how much tax-free cash you have within your AJ Bell SIPP, you need to go to our 'manage my SIPP' section of the website, here.
Whilst in this section, there’s a green box called 'amount I haven't accessed'. Your tax-free cash left is 25% of whatever cash is present within that box on the site. If you only see a 'amount I have accessed' box with a cash balance within that box, it means you’ve fully crystallised your SIPP and no longer have any tax-free cash and need to take income to access your SIPP.
