Property taxes cost most real estate investors and homeowners thousands of dollars each year — per property. 

Owners can protest the assessed value of their property. But the process isn’t always easy or transparent, and many municipalities only allow a narrow time window for protesting assessments. 

So, an entire industry has risen up to help property owners lower their tax bills by navigating the protest process for them. 

Considering hiring a property tax protest company to lower your own tax bill? Here’s what you need to know.

Understanding Property Tax Assessments

Unlike sales and income taxes, you can’t escape property taxes, no matter where you move in the US. Every state and jurisdiction imposes property taxes. 

That said, some jurisdictions charge far lower property tax rates than others. 

Local governments charge a percentage of your property’s assessed value each year as the property tax. The lower your assessed value, the less you pay in annual property taxes. 

Government workers called assessors estimate the market value of your property. They look at your property’s square footage, number of bedrooms and bathrooms, and comparable sales (comps) to come up with the assessment. 

But they don’t actually inspect the inside of your property. They don’t know whether you’ve recently remodeled the entire home or if you still have avocado green and mustard yellow appliances from the ‘70s. 

In other words, they often get your assessed value wrong. They can sometimes miss by $100,000 or more, leading to astronomically higher property tax bills. 

Which is precisely why homeowners and investors protest their assessed values — or pay a professional to do it for them.

Final Thoughts

From single-family homes and rental properties all the way up through 200-unit apartment complexes and commercial properties, property tax bills take a huge bite out of your bottom line. 

Local municipalities don’t design their assessment processes to be easy to contest. They design them for maximum tax revenue. 

Consider hiring a company to help you navigate the protest process and reduce your property tax bill for years to come.
