their taxable long-term capital gain is zero.
Step-by-step explanation:
The client was living there for two years, so it will have a tax exempt of 250,000
purchase at 300,000 sale at 500,000 = 200,000 - 250,000 = 0 taxable gain
This exclusion will be available in any house the person was living at least 2 years of the last 5 years.
