I use O’Connor and Associates to protest every year.
They’ve already had the hearing, and instead of an $18,000 increase for 2019, it was knocked back to a $6,000 increase.
Received their bill, which they claim is 50% of the tax savings. Once again, I made a call to point out that they didn’t use my homestead exemption in their calculations, and once again, they are going to generate a corrected bill.
This year the difference isn’t a large amount of money, but to me it’s the principle of the thing. It’s the 3rd year out of the last 5 that they’ve won for me, and every time they’ve had to correct their bill.
I imagine most people don’t run the numbers and don’t catch it, so the company is most likely taking in millions in fees that they really shouldn’t.
TLDR: after receiving a bill from one of the tax protest companies, run the numbers yourself to see if they are actually saving you what they say they are.
