Identify the account correctly
Traditional SEP and SIMPLE IRA balances generally enter the applicable traditional IRA analysis. Do not substitute an employer 401(k) balance for an IRA balance or assume every employer-sponsored account has the same treatment.
Check transfer restrictions
SIMPLE IRAs have a two-year participation restriction on certain transfers. Confirm the applicable date and permitted destination before modeling a reverse rollover. Ask the plan administrator and your tax adviser about the specific account.
