@shawsteve - the calculator is more comprehensive and will accomodate SS income.

when you state 'next year', I assume you mean you will begin SS in 2024. Therefore, as this calculator is set for 2023, it will slightly OVERSTATE your taxes. Whatever the tax liability is bite is ("total tax before credits" subtotal), reduce by ~3% for the expected inflation adjustment that is to occur.
