NonDividend Distributions and Cost Basis

[Allthingsmustpass]

For NonDividend Distributions, I have 8 lots purchased over a 6 month period in 2019 and 2020.  My brokerage is reducing the cost basis by the distributions.   For the reporting of capital gains once the cost basis reaches $0, do I look at the total for the 8 lots and the average cost basis, or do I need to report on a lot by lot basis?

And will my brokerage let me know how much the Capital Gains are for that tax year?

Those non-dividend distributions (NDD) are treated as a return of capital (ROC), reducing your tax basis. Once basis hits zero; any further NDDs are long-term capital gains because the stock has been held more than a year.  Each ROC distribution is prorated among the shares held. If you held 1000 shares all year, and the ROC was $1000, each share would be reduced by $1.
