Welcome to the new Mainstar Trust website!

Open a Mainstar Account

Mainstar Trust offers two convenient ways to open an account

  • To open an account by email, fax or mail, please go to the Forms section of our website and download the applicable forms.
  • To open an account online, please choose the account type below and proceed to the Online Application. Only the account options listed below can be established online.

Traditional IRA

Make contributions with money you may be able to deduct on your tax return. With a Traditional IRA, transactions in the account are not subject to tax while still in the account. Upon withdrawal, amounts are subject to federal income tax.

Roth IRA

Make contributions with money on which you’ve already paid taxes. Money in your Roth IRA can potentially grow tax-free, including tax-free withdrawals, provided that certain conditions are met.

Simplified Employee Pension Plan

A defined contribution plan, which allows employers to make contributions to individual employee accounts (similar to IRAs). Employees may also make pre-tax contributions to these accounts.
