How to account for IBIT fees when I purchased shares at different times

[alessiog]

I purchased shares of IBIT at 3 different times. I received my 1099-B.  For each month, there a small sale for the administrators to recover their fees.  Problem is I have 3 different purchase dates of varying amounts of shares. Do I need to pro-rate the fee across all three groups of shares? Or is there a simpler way to do this?

Check your 1099-B for the cost basis of these fees. It may have already been calculated for you. There are options if not:

Option 1 - most accurate -specific identification - you would pro-rate the fee based on your holdings at the time of each sale. For example: 100 shares Lot A, 50 shares Lot B means 2/3 fee from Lot A and 1/3 from Lot B. That is a lot of math for 12 months of fees.

Option 2 - First In First Out - the default method for securities. Attribute all the fees to your oldest shares first until they are all sold. Easy to track purchase date and cost basis.

Once you have your totals, you can add them together and just enter one line for the fee sales summary and use either various or oldest lot date along with sold date of 12/31/2025.

Thanks. I pro-rated the fees. Figure that it is good enough.
