Question on Cap Gains taxes/ Section 121 Exclusion

[Steve K.]

Question on section 121 exclusion for cap gains, specifically the timing of needing to live in the property for 2 of the last 5 years. Does anyone know off-hand if that is for the calendar year or exact dates? Assuming exact dates. I have a client looking to sell who moved in to her house on 10/2/22. She's wondering if she needs to wait until October to sell in order to qualify for section 121? Would it be pro-rated a t all if she were to sell a few months before hitting the 2 year mark? Any other strategies to avoid those cap gains on this sale? I know it's a question for her CPA, which is what I told her obviously, but I'm also just curious myself and thought it might be possible to find our answer more quickly from all the brilliant CPA's on here. TIA!
