There are several things going on in the above comments.
1. If you owned the home at least 2 years, you can exclude the first $250,000 of gain (or $500,000 if married filing jointly.)
2. If you owned the home less than 2 years but meet certain tests for unforeseen financial hardship, you can get a partial exclusion of the gain. These circumstances are described in publication 523. https://www.irs.gov/pub/irs-pdf/p523.pdf
3. Selling just because you prefer a different school district would usually not qualify you for a partial exclusion. If you owned more than 1 but less than 2 years, the gain is taxable as a long term capital gain and must be reported on your tax return.
4. The long term capital gains rate is zero for income levels up to $80,800 for 2021, and 15% above that. However, the gain from your home counts in determining your income, not just your wages. Your total income will be $166,000. With wages of $48,000, minus the standard deduction of $25,100 gives $22,900. That means that the first $57,900 of the gain will be taxed at the 0% rate (80,800 minus 22,900) and the remaining $60,100 will be taxed at 15%.
