RMD (Required Minimum Distribution) prorating of taxes (and maybe income)

I will take Required Min Distribution (RMD) from my IRA in Dec of this year, paying both Fed and State taxes (withholding) on that in Dec.

I want to report the uneven income I get on form 2210 (Fed) and 5805 (State) to avoid tax penalties.

• Can I report BOTH the 2025 RMD Fed taxes AND State taxes actually paid in Dec, as though they were paid prorated during the year. For example, if I pay $12,000 of State taxes in Dec on my RMD taken in Dec, can I report that on State form 5805 as $3000 paid by end March (3 months), $5000 paid by end May (5 months), $9000 paid by end Sept (9 months) etc. Similarly can I prorate the Fed taxes on the Fed form 2210.

• If I can do this (i.e. prorate the taxes paid), then do I report the INCOME from the RMD as prorated in the same manner as above OR can I report the income as received just in Dec (when it was actually received) - meaning the income shows as received in Dec but the taxes show as prorated throughout the year.
