What percentage should I choose for my SSDI income tax withholding?

[Nero1]

I've paid estimated taxes every year for my SSDI (and other income), but it's difficult to calculate correctly because my total income every year can be unpredictable. I heard I can fill out the voluntary withholding form, W4-V: https://www.ssa.gov/benefits/retirement/planner/taxwithold.html#:~:text=If%20you%20are%20already%20r....

Which percentage withholding should I choose -  7, 10, 12, or 22%? Please point me in the right direction on how to determine the best % withholding for me.

No one on this forum can tell you how much you need to withhold  ... look at your return.  What is your tax rate ?  How much are you short ?  Which % rate is closest to the amount you are needing ?   And you can also increase your withholdings on other income sources and/or pay in estimated payments.

It depends on how much other income you have.  It may not be taxable.  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

.Personally I just pay the quarterly estimates and don't have Social Security withholding.
