Up to tax year 2017, investment expenses were part of miscellaneous itemized deductions subject to the 2% of AGI floor.
Under the Tax Cuts
and Jobs Act, the miscellaneous itemized deductions subject to the
2% of AGI floor are suspended for expenses incurred after December 31, 2017
through 2025.
Therefore, your
investment expenses are no longer deductible for tax year 2018.
