Due to Open Banking regulations, there is no ability to share bank accounts or transactions across separate TaxTank accounts.

If you share a bank account with your wife, husband, partner and you both use TaxTank, you will need to allocate any transactions that relate to your partner as a ‘Personal’ transaction so it doesn't affect your tax summary.

When allocating bank transactions you can choose the ‘Personal’ icon to see the available personal categories or you can add your own custom personal category.
