Check My TLH Wash Sale Calculation?
« on: March 20, 2020, 09:45:05 AM »
I did an exchange of VTSAX for VFIAX on Monday for tax loss harvesting purposes.  Unfortunately, I didn't think about the 30 days BEFORE component of the wash sale rules.  Oops.

I used Specific ID for the cost basis for my sale.  In the 30 days before the sale, I bought about 16 shares of VTSAX, $1,220 worth, in two different transactions.  Both of these lots were sold as part of the exchange.  Am I correct in thinking that if my total loss on the sale was $3,700, and the two lots that were purchased in the prior 30 days contributed to $300 of that loss, then my allowable loss is $3,400?  (I understand that the max capital loss against ordinary income is $3K, I just overshot it a bit to ensure I didn't need to do another transaction to max my 2020 tax year TLH move, figuring I could carryforward any excess, or use it to offset and ST gains harvested later in the year.)

You never actually lose any losses under the wash sale rules. They're just delayed by changing the cost basis of the "bought" shares.

With a quick glance, you can claim the full loss with these transactions.
