Confused about AVI? Here's some helpful tips

* To find what your tax bill might be next year, go to avicalculator.phila.gov.

* If you own your house, you may be eligible for a tax break called the homestead exemption, which would lower the taxable value of your home. Go to phila.gov/opa to apply. The deadline is July 31.

* If you think the city overestimated your home's value, the deadline to file an informal appeal of your assessment is Sunday. Go to the same site listed above.

* Mayor Nutter has proposed a 1.32 percent property-tax rate and a $15,000 homestead exemption. He also wants to set aside $30 million for tax-relief grants.

* Council will debate those proposals and other AVI tweaks, including one that could phase in property increases and decreases over a few years, during this spring's budget process.
