1. Homebuyer tax credits

If you purchase your first home before April 30, 2010, you're entitled to a tax credit of up to $8,000. If you currently own a home, but sell it to purchase another home before April 30, 2010, you're eligible for a federal tax credit of up to $6,500.

2. Deductions for loan fees

Typically, you can deduct the "prepaid interest" you paid when you got your mortgage loan. That includes points, loan origination fees, and loan discount fees listed on your settlement statement, even if the seller paid those fees for you. Each time you refinance your home, you can deduct prepaid interest fees.

However, you must meet certain requirements to take the prepaid interest deductions when you purchase or refinance your home. Check with your accountant to be sure you're following the rules.

3. Property tax deductions

In the year you purchase your home, you're entitled to deduct the real estate taxes you paid at the closing table. You can continue to deduct the property taxes you pay each year.

4. The mortgage interest deduction

Every year, you can deduct the amount of interest and late charges you pay on your mortgage and home equity loans, though there are limitations. If you're required to purchase private mortgage insurance (PMI) because you made a downpayment of less than 20% on your home, you can also deduct those premiums as mortgage interest expenses.

5. Home office expenses

If you have a home office you use only for business, you may be eligible to deduct the prorated costs of your mortgage, insurance, and other expenses related to that space. The government scrutinizes home-office deductions closely. Be sure you're entitled to the deductions before claiming them.

6. The costs of selling your home

In the year you sell your home, you can deduct the costs of selling it, including real estate commissions, title insurance, legal fees, advertising, administrative costs, and inspection fees. You can also deduct decorating or repair costs you incur in the 90 days before you sell your home.

7. The gain on your home

If you lived in your home for at least two of the previous five years before you sell it, the government lets you to take up to $250,000 of profit on the sale of your home tax free. That amount is doubled for married couples. This deduction isn't available on rental or second homes.

The government also allows you to subtract from your home sale profit any amounts you spend on improvements, such as window replacement, siding, or a kitchen remodel. Those deductions are in addition to the tax credits you can receive in 2010 for making energy-saving upgrades. Money invested for routine maintenance and repairs doesn't count.
