Calculate SS tax in reirement for married filing jointly

[Pegcabral]

Hi,

Our  2024 tax return was corrected by IRS due to a mis calculation of our social security income tax percentage. We did get a refund after it was corrected, so we calculted too high apparently. 

Please advise how to simply calculate our ss income tax percentage correctly for 2025, also if we need to amend prior years.

Thank you.

You do not have to calculate it if you enter your SSA1099's correctly.   The software does all of the calculations for you.    If you are filing a joint return, you need to make sure you enter each SSA1099 under the correct spouse's name.  And watch carefully for the screen that asks if you had income from a foreign country---that screen messed a lot of people up.   Check your Form 1040 and make sure that you see amounts on lines 6a and 6b.

You don’t calculate that yourself.  Turbo Tax automatically calculates the taxable amount.   Did you enter the full amount of SS?  Social Security is on 1040 line 6a and any taxable amount on 6b.   Seems odd the IRS gave you a refund.  Usually they say you didn’t report the right taxable amount and owe more tax.

If you calculated it yourself where or how did you enter it?

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

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.

Or use the IRS worksheet in the 1040 instructions page 32

I calculated myself 

I may use turbo tax for 2025

My husband receives a pension, I work part time and our total income for married filing jointly exceeds the $32,000

Did you use the 703 worksheet on the back of the SSA-1099?   The 703 is a worksheet for you to see how much of SS is taxable but it can be tricky to fill out and you might not come up with the right amount.

And on your other posts I figured you over reported the taxable amount on line 6b by $8.  How much more refund did you get?
