have client who owned 2 condo’s. sold them both in 2013. accountant asked for her tax returns going back over 20yrs ago (cant believe she had them). He said he has to add back in the depreciation you took over the 20yrs. Now her tax bill is over 30k.

Is this correct or should they just be cost paid for condo’s and upkeep = cost basis – the selling price = capital gains you pay tax on?

thank you,
Douglas
