Social Security tax withholding - calculated on gross benefit or after Medicare deduction?

The withholding is calculated on your gross benefit amount, before any deductions like Medicare premiums. So if your gross benefit is $2,450 and you selected 10% withholding, they'll withhold $245 for federal taxes. Then they'll also subtract your $210 Medicare premium, leaving you with a net payment of $1,995 each month.

My tax guy told me its on the FULL amount before ANY deductions. Learned that the hard way last year!!

Just to add to what others have said - I've been getting SS for 5 years now, and the withholding is definitely taken from the gross amount before Medicare is deducted. On your SSA statement, you'll see it listed in this order: gross benefit, then tax withholding, then Medicare premium, then your net payment. If you have MySSA account online, you can see this breakdown clearly on your benefit verification letter.

Has anyone tried calling SSA to confirm this?? I've been trying for DAYS and cant get through on their 800 number!!! So frustrating!!!! Their phone system is the WORST!

when i first got my ss benefits i didnt do any withholding and BOY was that a mistake... owed so much at tax time! definitely smart to withhold something if ur benefit is taxable

My sister said they sometimes mess up the withholding when you first request it. Make sure you check your first payment after the W-4V goes through to confirm they got it right!!

You made a smart move with the W-4V! Just remember that if your financial situation changes (like you start working part-time or have other income sources), you might need to adjust your withholding percentage. The 10% might be enough, but some people need to withhold more depending on their total income. I had to increase mine to 15% after I started taking distributions from my IRA.

I work at a local SSA field office and can confirm what everyone else has said - withholding is definitely calculated on your gross benefit amount before any deductions. So your $245 withholding calculation is correct. One thing I'd add is that you should receive a 1099-SSA at the end of the year showing your total benefits paid AND the total federal taxes withheld, which makes tax filing much easier. Also, if you ever need to change your withholding percentage, you can submit a new W-4V anytime - it doesn't have to wait until the next tax year.

Just a heads-up. I think that the Voluntary Tax Withholding option that's now available online via SSA dot gov might be calculating the withdrawal incorrectly, because it did so with my benefit. From my benefit of $1351, 22% would have been $297.22. Instead, they took out only $256.50, which is more than a $41 difference for just one month. Somehow, the online process had incorrectly subtracted the $185 premium from my benefit and then applied the withholding of 22% to the reduced amount. From what I've read, it seems that people who submit the official tax form rather than using the online form *might* get their withdrawal computed correctly.
