Your corporation is a separate entity from you.

The board of directors must hold a meeting and resolve to open each and every financial account of the corporation. It must also state who will have authority to transact in the account.

This must be recorded in the minutes of the meeting of the board of directors.

The secretary of the corporation must draw up a resolution and sign it, stating that the board of directors has resolved to open this account.

The secretary of the corporation must sign the account forms at the financial institution when it is opened, swearing that the board of directors of the corporation has resolved to open this account.

This must be done according to the laws of the state that you have incorporated in. Even if you are the sole person in the corporation. You hold all the hats. In my state, the president of the corporation may also hold any other office, except corporate secretary.

To do otherwise, is to leave yourself liable for the debts of the corporation.

Consider filing for S-Corp status with the IRS, which frees your corporation from Federal Income Taxes, except certain capital gains. You need to check with them to see what applies to your corporation.

You may wish to sell your investments and use the money to purchase more shares of stock in your corporation, to get the money into the corporation, or lend it to the corporation.

FYI: An institutional account is one held by a financial institution, I am not sure that is what you should be considering. These are companies that invest millions of dollars of other people’s money, and charge the investors a fee for it.
