ADP Payroll Services Reviews

Horrible people at ADP. I’m not sure why none of them can comprehend to change my cell phone number and update it so I can access my ADP account. It’s very frustrating that I’ve reported this to my employer five times and he’s told ADP to update my cell phone number and remove my old phone number for verification.

We use ADP for our company payroll, and we have run into so many issues with the filing of our South Carolina payroll taxes. (We file for 3 states and only SC is a problem for them.) They either do not file it at all, file it and it is rejected, and they do not follow through until you ask for a supervisor to call you, and even then the problem just "goes away" somehow. When I open a ticket for a problem they do not respond, and even when I follow up inquiring about it they still do no respond. I have seen this with other companies who off shore their customer service and it has been their demise. I am currently waiting for a response on yet another problem with the SC first quarter taxes that were rejected. Until customer service is improved with knowledgeable humans again be sure you know the payroll tax process yourself before choosing them.

The login experience with ADP has been extremely frustrating. It appears as though passwords are not being reliably recognized or retained during authentication. Even when entering the correct user ID and password, the system repeatedly returns an “incorrect credentials” error. This forces me to go through the “Need help signing in” flow and reset my password. What’s more concerning is that even after successfully updating the password, attempting to log in again with the new credentials results in the same error. This creates a continuous loop of failed logins and password resets. This issue has occurred multiple times and significantly impacts usability. Overall, this has been a very poor and frustrating experience.

HORRIBLE BORDERING ON FRAUD. If you want to get a full time job reading dozens of ADP emails, being asked to waste hours of your life watching training videos, fight an impossible to navigate website that can't let you input your address and after paying fees not be able to contribute to your 401K, go with ADP retirement. If you are looking for a simple intuitive web site and responsive customer support to contribute to your 401K--RUN. Don't think more than a second--find yourself another company to manage your 401K. ADP Retirement services are worse than AWFUL!!!

Very frustrating company to deal with. If you ever need information and can't get it in their endless phone prompts when you call, good luck getting anyone to return your call. Emails go unanswered and voice mails go into a black hole. You may as well be calling the White House and ask to speak to the president. Terrible customer service.

I am a small business owner and recently attempted to use ADP for payroll services. Unfortunately, my experience has been extremely frustrating and concerning. During the initial process, I had multiple scheduled appointments where ADP representatives did not show up. After that, I was informed that ADP had made a “business decision” not to move forward with my account — but no explanation was ever provided. Hoping to resolve the situation, I later had a sales representative reach out to me directly after seeing a review I posted. They initially offered to help, but shortly after, I was told they were instructed not to communicate with me at all.

The do not back consumers on fraudulent charges. I would not use them if you don't have to. I lost money and they advise me to reopen or dispute a claim I have for a fraud charge I have to write a letter to their office in CA and I'm in GA. Obviously this is not as important to them as it is to me or any other consumer in this case.

DO NOT USE THIS COMPANY!! In 44 years of filing taxes, I have owed for Federal 2 times. My employer for the last 2 years uses ADP, and I am Single, no dependents, do not itemize and claimed 1 in 2024 (NOT head of household) and owed roughly 1500 for 2024 and now will owe again roughly the same amount for 2025. In reviewing my pay stubs, the federal withholding is all over the place. Sometimes NO withholding, sometimes 3%, sometimes 9%. THIS IS NOT ROCKET SCIENCE! I ONLY WISH I WAS WATCHING MORE CAREFULLY!!! Now I'll need to pay back what ADP failed to withhold, plus 7%, interest, and penalties. My FLEX account now shows Single 0 as I changed it out of desperation so I won't owe again for 2026, and not much has changed. What to do?

I called ADP today because I did not receive my W2s for 2025 when I received an email saying it was delivered but not to my address. I called and spoke to 4 different reps and stayed on the phone for 2.5 hours only to have been disconnected. My problem was not resolved.

Processing payroll is pretty easy with ADP and their reports are good. However, their tax department is terrible. If a notice is anything other than "pay this amount," they cannot or will not figure it out. Several times, I have figured out what happened for them, and they still do not understand or follow through. They do not read notices or documentation, and they themselves are unreachable. You cannot call them, add notes to an uploaded document, or email them. They also close cases that are not resolved, which means we have to re-upload documents and start all over again.
