Property taxes are still on the upswing in many parts of the U.S. To help get a handle on your property taxes, here's a look at what goes into determining your bill and a few ideas that may help to reduce it.

Background

Why this matters: Even if your home's value doesn't change, your tax bill can go up if any of the taxing authorities raise their rates. And while setting the tax rates is usually a legislative process, establishing the value of your property often has judgement applied.

Ideas to lower your property tax bill

• Understand and adhere to the calendar. Challenging the value of your property requires an understanding of the process for doing so AND hitting the proper deadlines. If there's an appeals process, know it and make sure you meet their deadlines or you could be out of luck for that year.

• Challenge your property's assessed value. You have the right to appeal your property's assessment by filing a formal appeal with your local assessor. If you can show your home was assessed for more than it's worth compared to similar homes, you might get your tax bill reduced. If you want to appeal, you need to act fast. There are typically just a few weeks each year to appeal your assessment. So mark the date and gather evidence early if you plan to dispute it. But do your homework! Collect actual sales of similar properties that show a lower sales price, and be ready to defend the condition of your property if it is an older home. Assessors are quick to dismiss complainers with no facts to back them up.

• Claim all exemptions and eligible tax breaks. Contact your local assessor's office to see what exemptions you can claim. Many states and counties offer breaks for veterans, people with disabilities, low-income households, older residents and those in designated areas like historical districts or disaster zones.

• Compare local tax rates before you buy or move. Property taxes are determined locally by counties, cities, or school districts, which means two identical homes in nearby ZIP codes can have drastically different tax bills. So always check the local tax rate before you buy or move. Look at the history of property taxes in your target neighborhood and see how it changed over the past several years. Then compare it with other homes in the area to ensure the rate increase is consistently applied.

• Calculate the tax impact of renovations before building. Adding a new deck or renovating your kitchen may increase your home's assessed value, especially if the county finds out through permits or a property inspection. So even if you don't sell your home, upgrades can mean a bigger tax bill. Some areas reassess properties automatically after building permits are pulled. So always factor in long-term tax implications when upgrading your home.

• Review your lot details for unused land. Your property tax bill covers not only the value of your house, but also the value of your land. If part of your property can't be used, like wetlands, steep slopes, or areas with easements, ask your assessor if your bill can be adjusted.

Property taxes are one of the few taxes you can actually fight and get lowered. But you can't do that if you don't understand how the system works. So don't just pay the bill without looking at it. There's >often money to be saved if you understand the details.
