Investment Deductions for State Filing

carriskoul — Mon, 09 Mar 2026 05:26:00 GMT

I have federally tax-exempt interest dividends that get taxed as Illinois income. Under the TT interview, it asks "Any Deductible Expenses?" In 2021, did you pay any expenses that:

Were used to maintain investments that are exempt from federal tax, but are taxable to Illinois?
Were disallowed on your federal return because you took a credit for them?"

Are the "advisory fees" I paid to my brokerage account throughout 2021 that held this asset that generated the subject income a deductible expense per the first bullet?

Thanks - Carris

Yes, if the expenses were necessary to maintain the account they are deductible against the dividend income from the investment.

Thank you AliciaP1.

This was the fee the brokerage charged as a percentage of my portfolio value. So if let’s say I paid the brokerage $1,000 to manage my portfolio for the year, then I can deduct that $1,000 on my state return even though the dividend income was from a portion of the portfolio. Is this correct?

You can take, as a subtraction against Illinois income, the portion of the $1,000 that relates to the portion of your investment that was exempt from federal tax, but taxable by Illinois.

If your entire portfolio is the federally tax-exempt income, you can claim the entire expense. If, say, 25% of the portfolio is reflected by this income, you can claim 25%. Make a reasonable estimate.

See Schedule M IL-1040 Instructions for more information.
