Despite the reduction in the penalty for missing required minimum distributions (RMDs) in the new SECURE 2.0 law, it looks like you will still be able to get the IRS to waive the penalty altogether.
Before 2023, if you missed an RMD the IRS could impose a penalty equal to 50% of the missed amount. However, the IRS almost always waived the penalty if you took the RMD and filed Form 5329 (with a reasonable cause explanation) with the IRS.
