The basic computation for determining the amount of taxable Social Security is shown here.
Combined Income = Half of Social Security + AGI + Tax Exempt Interest
Social Security Income = Combined Income - Adjustments
Social Security Range = MFJ $32,000 - $44,000
Other $25,000 - $34,000
If Social Security Income < Social Security Range
Taxable Amount = 0
If Social Security Income within Social Security Range
Taxable Amount = 0 - 50%
If Social Security Income above Social Security Range
Taxable Amount = 0 - 85%
