Why didn't the tax due drop right after I entered some $6,700 of investment interest expense (broker margin interest)?

There are multiple ways adding in the investment interest expense would not decrease federal tax. A good place to start would be to revisit:

  • Form 4952
    • Your investment interest expense deduction is limited to your net investment income.
    • If you did not have sufficient net investment income, your investment interest expense would be disallowed and carried forward to 2019.
  • Form 1040 line 8
    • You are permitted to take the higher of your itemized deductions or the standard deduction.
    • Tax Reform increased the standard deduction for all taxpayers in 2018.
    • If $6,700 of investment interest expense was allowed but did not push your total itemized deductions over the standard deduction, there would be no drop in tax.
