There are many dynamics that can affect your tax liability upon selling your home. These issues include whether you purchased the home or inherited it, if you used your home for business or rental purposes, costs associated with selling your home, and any home improvements and additions that you've undertaken.

The Federal Taxpayer Relief Act of 1997 provides capital gains tax exclusions of up to $500,000 for married taxpayers filing jointly and $250,000 for single taxpayers or married taxpayers filing separately. Current capitol gains rates are 20 percent for those in upper tax brackets and 10 percent for those in lower tax brackets. Overall capital gains rates have been lowered even further -- to 18 percent and 8 percent respectively -- for assets acquired after December 31, 2000, and held five years or more.

To qualify for this tax break, you must have used the home as your primary residence for at least two of the prior five years; these two years don't have to be consecutive. If you relocate for your job but don't meet the requirement, you may be allowed to take a capital gains exclusion proportionate to your circumstances. This exclusion is not a one-time benefit; you may take advantage of it once every two years as long as you meet the qualifications.

The tax rules differ when you sell a home that you've inherited. If you sell the inherited home for a profit, you're required to pay federal and state taxes on the gain. If you keep the house as a second residence and/or eventually move into it after renting it to tenants, you may take the $250,000/$500,000 capital gains tax exclusion if you meet the requirements. When you're deciding what to do with inherited property, you should consider the current estate tax laws and basis practices.

Beyond these general rules, it's wise to discuss your home's sale with a tax professional who can advise you on tax benefits in more detail.
