(snip)
As of March 27, the agency will begin mailing notices about the new 100 percent withholding rate, rather than the recent adjustment of just 10 percent. The withholding rate change applies to new overpayments related to Social Security benefits. The withholding rate for current beneficiaries with an overpayment before March 27 will not change and no action is required. The withholding rate for Supplemental Security Income overpayments remains 10 percent.
People who are overpaid after March 27 will automatically be placed in full recovery at a rate of 100 percent of the Social Security payment. If someone cannot afford full recovery of their overpayment, they can contact Social Security at 1-800-772-1213 or their local office to request a lower rate of recovery.
Additionally, people have the right to appeal the overpayment decision or the amount. They can ask Social Security to waive collection of the overpayment, if they believe it was not their fault and cant afford to pay it back. The agency does not pursue recoveries while an initial appeal or waiver is pending.
(emphasis as it appears at the site)
I am guessing that means that if there is a problem
with the next checks that get sent out after today, then the 100% withholding will come out of those. Any over-payments on previous checks, will still have the old rate.
Can't guarantee with this administration whether they will backtrack on any "promise".
