On its consolidated Form 1099-B, IB lists four items. Which of these are deductible?
Can someone confirm whether these "Other fees paid" are deductible and where, ideally by citing a source?
- "Margin Interest Paid" - this is deductible for sure, per TurboTax on the "Investment Interest Expenses" page
- Payment in Lieu Paid - no idea what this is, but it's 0 anyway
- Advisory Fees Paid - same
- Other Fees Paid - this is over $1k. What are these fees? Market data?
