New W-4P for pension systems grace period - any other issues?

[Ryan]

With the mandate for the new version of the W-4P being just 5 months away, we've encountered a unique issue and I'd like to see what other pension systems are doing.

We currently send out the old format form (Single or Married with number of allowances), but in December when we implement the new format form we'll literally have thousands of old format forms out to members. The IRS has given the computational bridge to enter an old format into the new format, so we can handle that during 2022 and into 2023. But I can't find any guidance for a "grace period" of accepting old forms. I know we'll get old forms signed in 2023 during the transition - I'd sure hate to send forms back to them and default them to the new "single with no adjustments" because they don't have a current form.

But my question to you: How long will you accept an old format form next year? (the ones in member's hands while they deliberate the start date of their pension)

Any other issues you've encountered with the new form mandate?
