For revocable trusts, the NCUA says that the "person who holds the power of revocation is deemed to be the owner of the funds in the account." Things can get even more complicated for joint revocable trust accounts. The bottom line, is that you should discuss any share balances in trust accounts with credit union staff to make sure you have a clear understanding of what is insured. Retirement accounts: If you have an individual retirement, or IRA, account at a credit union, the IRA is separately insured from your non-IRA accounts, for a total of up to $250,000. Traditional IRA, Roth IRA balances in the name of the same individual are added together and insured for a maximum of $250,000. Keogh retirement accounts are insured separately, so if you have $250,000 in traditional IRA and/or Roth IRA shares, plus a $250,000 Keogh account in the same NCUA-insured credit union, the total insured shares are $500,000. Business accounts: Accounts in the name of a corporation, partnership or association is separately insured to an aggregate limit of $250,00, provided the organization "is engaged in independent activity," which is defined by the NCUA as "an activity other than one directed solely at increasing insurance coverage."
