Retirement / Pension / Social Security- What % of social security income should be counted in 2018

[rexispoohbear]

I think turbo tax should have included a % of our social security as income but it did not.

On the new 1040 Social Security is on line 5a and 5b.    

To see the Social Security Benefits Calculation Worksheet  in Turbo Tax Online version you would have to save your return with all the worksheets to your computer.   Or if you are using the Desktop CD/Download Software you can switch to Forms Mode (click Forms in the upper right) and click on SS in the list on the left side.

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

The portion of your Social Security Benefits that are taxable (if any) is based on your Modified Adjusted Gross Income (MAGI). 

Check out IRS Pub 915, Page 7, to view the Worksheet used to determine the taxable amount of your Social Security Benefits.
