The availability of off-the-shelf tax software makes a self-prepared tax return a legitimate, low-cost alternative. If you just have a couple of W-2s and a few deductions, it may make perfect sense to do it yourself. But, for a lot of people it's truly not the best option. Garbage in, garbage out: Your tax software will ask questions to guide you through completion of your return.

An enrolled agent is a person who has earned the privilege of representing taxpayers before the Internal Revenue Service by either passing a stringent and comprehensive examination covering individual and business tax returns and representation of clients before the IRS or through experience as a former IRS employee.

I called to ask about tax implications regarding 401K withdrawal and Oscar answered my questions. He was very nice and listened to my concerns. He seems knowledgeable and received excellent reviews which is why I reached out to him first. In the future for tax services, I would DEFINITELY go to him for the service.

I recently went here and saw Oscar A. who did a great job on my taxes. This was my 1st time with this business and I will definitely be going back next year. Oscar was a very good communicator, knowledgable, extremely thorough & filed my taxes in a timely manner.
He was able to see me the next day after I called. His office is very clean & Covid safe. He wore a mask & has a large plexiglass divider on the edge of his desk. You are sitting a good 6 feet away from him.
I am really picky and have been looking for a long time for a tax accountant that I am comfortable with. Communication

Oscar took the time to walk me through line by line of for my personal taxes. He was quick with response times and genuinely seemed concerned to do the right thing for my family. He actually made tax preparation a pleasant experience for me. I will absolutely use his services again.

I just wanted to let everybody know that Oscar from Robert Abbott is probably one of the nicest gentleman you could ever talk to. He is not my actual CPA but he took the time out on a Saturday to speak with me and give me some sound advice that has allowed me to really think about personal values my kids in the future. I believe that if I will need any financial support in the future that I will be contacting Robert Abbott and working with Oscar. Please see this guy he is great

This was probably my best experience with a tax service. Everything was broken down and explained to me really clearly. I received a list of everything I needed and they truly care to make sure you understand your return. I was referred by a friend and I'm happy he showed me this business. If you're in need of a great tax service or you want to get a breakdown of how taxes work, try this place.

My husband and I have been going to him for 2 or 3 years now and we could not have better things to say about his services. We were referred by a friend and now we have referred our friends and family because he is that good! We moved 45 minutes away and we still make the drive every tax season just because we trust him and appreciate his services. Highly recommend him if you're looking for a trustworthy tax professional.

I needed to find a tax preparer to help file my deceased brothers final returns. I did a lot of research before making my decision. I went with Oscar at Robert Abbott Tax Service and I couldn't have been more pleased! So much so, I also made an appointment to have Oscar prepare ours. He was professional, considerate and thorough. Thanks Oscar!!

I've tried getting in contact with someone here 4 times since beginning of February and can't get a hold on anybody. Maybe the office is closed now?

This is our first appointment with Oscar. We were with Gerry Pusateri for over 20 years so I was nervous about finding someone we would trust and be comfortable with.
Oscar is an Enrolled Agent. We were able to get an appointment the same week. Our appointment was in February so I'm sure that helped.
Our appointment went smooth. Oscar made us feel at ease. He triple checked all numbers he entered while we were with him. We knew if we had to pay or get a refund and how much by the time our appointment was done. His rates were very reasonable.
He also offers virtual appointments, but we

Highly recommend Oscar at Robert Abbott! He's been doing my taxes for several years now (his mom did them prior to that) and he is amazing. He does the job effectively and quickly. He's very well informed in all the updated tax laws and can easily explain any questions you may have. His rates are reasonable and the service can't be beat.

I received a CP2000 form this year and was having difficulty finding a professional that had availability to help me before my deadline of 12/30. When I reached out to Oscar (whom a coworker had previously used), he replied within the same day and quickly laid out everything we would need to do to get started. He provided a secure client portal through Intuit where I could upload all my documents, which was super helpful as I'd prefer not to meet face to face during covid. Even with the holidays this week, he was so responsive to my emails, made time to complete a 1040 amendment for me, and

Absolutely amazing job with preparing my taxes. Everything was explained and care taken with every step. There is a screen for the client to view exactly what is entered and you follow along as well. Every line was checked, checked again and then checked once more for accuracy. It was explained to us how to prepare for next year and every question answered.
