One thing that sometimes surprises homeowners during a sale:
Purchasing another home generally does not defer or eliminate the taxable gain from the sale of a primary residence.
Under current tax law, the main benefit is typically the Section 121 exclusion, which may allow married taxpayers filing jointly to exclude up to $500,000 of gain if the ownership and use requirements are met.
Anything above that amount may still be subject to:
• Federal capital gains tax
• Net Investment Income Tax
• California income tax and mental health tax (if applicable)
Also important:
Capital improvements, selling expenses, and original purchase closing costs can all play a major role in reducing the taxable gain.
Every situation is different, especially with large gains, rentals, inherited property, mixed-use homes, moves between states, etc., so projections ahead of time can be very helpful.
