Specialists in Alternative Investments

Some IRA custodians only offer standard investment options like public stocks, CDs, and mutual funds. At Mainstar Trust, we offer you the ability to truly diversify and personalize your IRA investments through a wide variety of alternative investments at a cost you can afford.

While some custodians shy away from processing non-traditional, alternative investments, Mainstar leans on years of experience in the financial industry to help you navigate your alternative investment choices.

What is a Custodian?

The custodian of an IRA must be a bank/trust company (federally or state-chartered), a federally insured credit union, or an entity approved by the IRS to act as custodian. The custodian is responsible for producing the legal documents to establish the IRA and accepting contributions to fund the IRA, including transfer or rollover assets. The custodian acts on behalf of the IRA to take control of the IRA investments and provides tax information to the account holder and IRS.

While not required by the IRS, some taxable accounts will utilize a custodian for ease of reporting and processing. The custodian will typically provide the same oversight for taxable accounts as it does for IRAs, but not necessarily all tax reporting.

We do not provide investment advice

Not all custodians allow all types of alternative investments, and not all custodians are experts at administering alternative assets. As a custodian, we electronically or physically hold customers’ securities for safekeeping. We accept a variety of self-directed IRA asset types, including real estate products, private lending, and private placements, for our customers to choose from.

We do not offer advice nor do we make investment decisions. We simply allow a wide range of investment options.

We are a regulated entity

We are a limited purpose trust company chartered in the state of Kansas. This means that we are routinely reviewed for our onsite safety, financial stability, and operational risk management systems. We are also required to perform routine audits to provide the highest level of asset protection.
