Even though they may try to convince us otherwise, property tax protest companies are not our friends. They don't just WANT but NEED our property values and taxes to go up year after year in order to profit. Of course they aren't directly to blame for those increases but they certainly capitalize on them. They start with the assumption that your property value (and most likely taxes) will always be 10% higher than the year before based on the homestead cap. If they manage to get your appraised value anything below that 10%, they charge a fee on the tax "savings". That means that they aren't necessarily trying to lower your taxes from the previous year (although that would make more sense). What they consider a success, and worthy of payment, is merely shaving a little off that 10% maximum. I also want to point out that their 50% fee is the highest I've seen out of all of the tax protest companies out there. After having used these types of services for a while, it has become clear that they don't actually do anything that homeowners couldn't do themselves, despite their claims that they're more effective. In fact, they seem to get less of a reduction because they are handling many, many protests all at once. For those reasons, O'Connor was a one and done for me. read more

I've used O'Connor & Associates for several years, hoping their "property tax reduction experts" would eventually deliver meaningful results. Unfortunately, the reductions have consistently been negligible -- usually less than one percent, despite the hours I spend gathering photos, documenting issues around my home, and preparing detailed evidence for them. This year was the breaking point. After expressing that we would not continue using their services without a better outcome, I reluctantly signed their agreement authorizing them to request and participate in a formal hearing on my behalf. I did my part -- again -- providing everything they asked for. A week ago, I received a letter from the county appraisal review board stating that the hearing scheduled for July 28, 2026 was not conducted because the representative from O'Connor & Associates: Did not provide any evidence or testimony, and Lacked proper authorization to act on my behalf, and/or Submitted an affidavit from an unauthorized agent. In other words, the hearing failed before it even began. When I contacted O'Connor & Associates for an explanation, they told me they were "waiting for a hearing date to be set" -- even though the county had already scheduled one, and their representative was listed as the participant. So now I'm left wondering: Did they simply not show up? Did they fail to submit the correct forms? Did they do anything at all? As of today, I still have no response or clarification from them. After years of minimal reductions, poor communication, and now a completely botched hearing, I can only advise others to be extremely cautious before using O'Connor & Associates for property tax protests. My experience suggests that the burden falls on the homeowner, while the "experts" provide little value -- and in this case, no representation at all. read more

O'Connor & Associates has been great for us, our businesses, and our ranch properties. They have been excellent communicators, letting us know exacting what was happening with our tax protests, renditions, and property taxes. My husband and I will continue to use them for all of our Property Tax needs. read more

Wrote a review about my horrible experience O'Connor contacted me and said they'd have someone call me. It's been two weeks. No one's contacted me. Pretty consistently poor customer service-everything is outsourced or feels like high school kids contacting you So disappointed in the lack of follow up! they can pay an attorney to threaten me when I have a letter stating that I do t owe money, it can't take the time to get their thugs to back off their mistake! read more

Do NOT trust this company. They double billed me for one of my properties. I paid both bills, my mistake, and they won't refund my overpayment. It's been two months. I get the same song and dance about how the checks been cut and my post office has lost it. They won't stop payment and reissue a check, they won't get me to the accounting department, they don't let me talk to their legal department, they just keep my money. Ridiculous. read more

No reduction in the two years I used them. When I asked on the chat how to remove myself from the continuation of their services they dragged out the conversation, asking for an opportunity to do better next year, blah, blah, wasting my time. I had to call in and THEN they said that cancellation would take a month! And THEN I have to call the county myself. read more

I would give 0 stars if such an option existed! they took my money and didn't even provide a tax reduction. Do not use these guys!!

I'm not sure these people are paying any attention to what they are doing. They have just lost another client after giving them the benefit of the doubt for far too long. read more

Wow- I thought it was just my bad experience. Apparently not! They don't even deserve 1 star, but zero is not an option... I would NOT recommend O'Connor & Associates! I was recovering from a serious illness, so we tried their service (ha!) for our Plano home in 2017. They failed to save us anything beyond the amount I was already offered by the County. It was a good thing I felt uneasy about O'Connor & drove all the way to the County the day of my hearing. Apparently the O'Connor rep showed up early & accepted the very same paltry adjustment the County had already offered me! That amount was already stated on my form to O'Connor as the amount offered to me, so they knew they saved us ZERO! That same day, I worked directly with the County & had our amount lowered significantly. O'Connor states you don't owe them anything unless they save you money, but they have continued to invoice me until April 2020. I continue to state why I don't owe them a penny. Very disappointing experience. read more

I would give them negative points if possible. I had a very bad experience at the office. Last year (2023) because I was very busy, I called the office on 5/4 to help me protest the property tax. But last year this office did nothing for me and property taxes stayed the same. I didn't ask them to protest for me this year（2024）, I protested myself. On 5/10/24 I filled out an online protest at efileprotest.colincad.org and received a response from the online protest on 5/15/24 and they took $6000 off my property assessment. Unexpectedly What's more, O'CONNOR actually gave me a bill and asked me to pay their service fee of more than one hundred US dollars. My own protest online was successful, but they actually came to collect money from me. How ridiculous. I advise everyone not to look for them, and be aware that once you create an account with them, it means that they have to provide services for you every year, and you don't even know. read more

Giving them your address and contact information automatically signs you up for an account. I was just doing a web inquiry for information about how they work. I had to call them to deactivate my account so be careful if you are just inquiring about their service. :-( read more

See all

I have had the worse experience with them. No communication nothing! Reductions are if any at all a minimum and they don't show up. Its a mill. They have tons of kids working for them answering phones and they have no knowledge of what is going on but they sure as hell want to collect fees. There are tons of these guys out there. Try it yourself instead on line. They should be embarrassed to even promote themselves read more

I hired O'Connor and Associates to represent me in protesting my Dallas County Appraisal District (DCAD) tax assessment. I spent a lot of time talking with them, filling out forms, providing information, etc. When I called the DCAD to find out what happened at my hearing, I was told that O'Connor and Associates didn't show up! They didn't even try, and they didn't tell me that they weren't going to show up. What a waste of my time! And my property taxes increased. read more

My 2017 Collin County tax value went up about 10%. I hired this firm. They said I did not need to be at the hearing, and they didn't notify when the hearing took place. I am not sure anyone from there even showed up since my value change $0 after the hearing. I would have been better off protesting by myself. Don't waste an opportunity using them. read more

Avoid O'Connor & Associates at all cost & find a better firm which would be anyone & everyone else in the DFW Metroplex. They have never gotten us a reduction & our valuations have skyrocketed. Finally we did it ourselves and easily got a quite significant reduction despite never having done it ourselves before. read more

These guys are the worst. They no showed my tax protest hearing and their customer service is all East Indians so you cannot understand what they are saying. Save yourself some stress and do not use them. Trust me. read more

These guys are the best ! I signed with them a year after I purchased my home. They were very professional and helpful whenever I called . Well this year, I received an invoice with their fee, because they got my taxes reduced by $12, 062 which means a tax savings of $346.00 ! their fee as contracted in 50 %( $173.36) which I think is fair since I can't do the work ....in addition - Im over 65 so my fee is 50% of the 50% ..I paid $86.00 . Thats a win in my book !! read more

I hired this company to protest my approximately 30% property tax hike in Plano, Texas. Their "agents" don't really communicate with you, and you have to call a switchboard to ask questions to an operator. They "saved" me $1200 on my assessment (not my tax bill), which is about the same amount the appraisal district offered to settle before I hired them. They don't share any type of strategy with you and I wouldn't waste my time or money hiring them again. I believe I could've gotten a better deal if I'd handled the protest hearing myself. read more
