Up to 85% of Social Security becomes taxable when all your other income plus 1/2 your social security, reaches:
Married Filing Jointly: $32,000
Single or head of household: $25,000
Married Filing Separately: 0
And.......You should not use the worksheet on the back of the SSA-1099. It can be complicated to figure out even though it looks simple. Turbo Tax figures it all out for you. When you enter 1/2 of your ss on line B it is not being subtracted from anything. It is being ADDED to ALL your other income to see if any of the ss will be taxable to you.
