withholding

Hi! That is a great question!  Planning ahead for taxes is never something we WANT to do, but it can really help avoid sticker shock at tax time.  To address this question you really need to know how much income  you have, other than your social security.  Your social security is not taxed until you have income the exceeds a certain threshold.  And then the percentage that is taxed is based on that other income. Up to 85% of your social security can be taxed if your income is over the max threshold.

You will pay tax on only 85 percent of your Social Security benefits, based on Internal Revenue Service (IRS) rules. If you:

• file a federal tax return as an "individual" and your combined income* is
  • between $25,000 and $34,000, you may have to pay income tax on up to 50 percent of your benefits.
  • more than $34,000, up to 85 percent of your benefits may be taxable.
• file a joint return, and you and your spouse have a combined income* that is
  • between $32,000 and $44,000, you may have to pay income tax on up to 50 percent of your benefits.
  • more than $44,000, up to 85 percent of your benefits may be taxable.
• are married and file a separate tax return, you probably will pay taxes on your benefits.

Here is a link to the SSA information on taxability of your SS benefits. https://www.ssa.gov/benefits/retirement/planner/taxes.html#:~:text=between%20%2425%2C000%20and%20%2434%2C000%2C%20you,your%20benefits%20may%20be%20taxable.

Then you have to consider how much your total income will be.  If you make over a certain amount you will need to apply the current tax rates so that you can estimate how much to withhold on your pension and your social security payments.
