What is the limit on crypto gain or loss that need to be reported?

[DaveF1006]

It depends. There is no limit to the gains or losses that can reported on cryptocurrency transactions. If you have a capital loss, you can only claim a $3000 capital loss in any one year. Net capital losses in excess of $3,000 can be carried forward indefinitely until the amount is exhausted or offset by future capital gains.

Thanks, I bought one of the crypto and sold it for about $40 gain using Robinhood platform. Do I need to report that?

[DaveF1006]

Yes, do report it even though it won't significantly impact your tax return.
