Can IRA losses be deducted in 2018

[DoninGA]

What type of IRA losses are you referring to?  Losses occurring within a tax deferred retirement account are not reported on nor deductible on a tax return.

[Carl]

Since an IRA is funded with "before tax" dollars and you didn't pay taxes on that money, then you have nothing to deduct from taxable income. You can't deduct that which you never paid taxes on in the first place.

 No.  Losses in your IRA cannot be deducted on your 2018 tax return.
