Frequently asked questions
Summit facilitates trust account arrangements for revocable and irrevocable trusts. To open or retitle an account in trust, visit a branch with the full trust agreement or Certificate of Trust, government-issued ID for all trustees, and the trust EIN (or grantor SSN for revocable trusts). Trust accounts receive separate NCUA coverage up to $250,000 per qualifying beneficiary, which can substantially increase coverage for accounts with multiple beneficiaries. Summit does not provide legal advice on trust structuring. Contact 608-243-5000 for details.
The Certificate Plus is a flexible certificate that allows additional deposits during the term, unlike a standard Certificate where the balance is fixed at opening. Both types earn competitive rates with dividends compounded and credited monthly. Standard Certificates require a $500 minimum and offer terms from 3 months to 5 years. Certificates can be started as or transferred to IRA Certificates later, penalty-free.
