I particularly appreciate the pre-filing questionnaire-which helps make gathering documents and preparation a breeze. The Tax Dome App is incredibly convenient for uploading files on the go.

I wanted to edit this review, because it made me sound like I reviewed while mad/upset…read more I have been working with this company for 5+ years, & I used to file single. Once I was married & we had complicated things to add, we made sure to go to Viet. I used to get to make an appointment with him in person & he answered any & all of my questions, before I filed. But sadly COVID hit & things changed to online. My husband & I have changed careers several times since 2022, & we had a baby, so there are several things to add into your taxes. This year, we spent over $15k in medical expenses, had our first child, & hoped we would get some kind of a tax refund. But unfortunately that didn't happen. When I asked about adding money to our IRAs, or why we didn't get to file itemized, or how else we can reduce our tax bracket, we were told it was a "paid question that required a paid appointment". Anyway, I think you can get your own taxes done for free or less than you're charged by this guy. He can't help you with basic questions without requiring money so... stay aware & ask questions!

I can't say enough good things about John Mao at Argus CPA. When our CPA unexpectedly retired and…read moreour corporate return was due on March 15, John came to the rescue.

Not only is he very knowledgeable (and you can tell from others who cannot answer your questions; they just keep on talking.), he is very kind, considerate of what our challenges are.

Terrific!

He asked lots of questions to make sure I was maximizing my refund and receiving all that I was entitled to. Thank goodness. Who doesn't look forward to free money these days? Good sense of humor and easy to talk to...not dry like your normal accountant/auditor/tax prep person...You know who I am talking about...the green visor staring at you from behind thick round glasses all the while pounding a ten key! If you are looking for a CPA to effectively, efficiently, and most importantly affordably complete your tax returns for current or prior years, Mr. Koch is and will continue to be my tax man for years to come!

The next step was to wait, to receive an email with further instructions. I never received the email, so I decided to call. He was rude from the start. I simply told him sir I did everything I was suppose to do. He was very adamant that I had to a mistake which I didn't. He didn't even try to look into the problem or see who I was filling for. I'm going to make sure my father save his $400 dollars from now on!

I needed emergency assistance filling some past taxes since I was moving out of town. I had a lot…read moreof concerns and questions since I had many 1099s as well as different investments in stocks and cryptocurrencies. Got on the phone with Will and he was able to reassure me and answer all the questions that I had before we got to work. Will is super knowledgeable when it comes to filling taxes with cryptocurrencies and investments which is something that 99% of any other CPAs struggle with. Due to my limited availability, we ended up opting to just have will file my taxes online via email. After sending him all the paperwork necessary, Will said he'd work out my taxes the day after. Rest assured the next day came by, and before filling, Will sent me a couple of forms that needed to be signed, and my taxes were done! Will is hands-down the best and most honest and ethical CPA I've ever worked with, he always goes above and beyond to answer any questions as well as give any recommendations of any blind spots you might have. I was so lucky to have him work on my Taxes and will definitely work with him on any future fillings. If you need a CPA who's super knowledgeable on Tax codes, investments such as stocks and cryptocurrencies, as well as getting started on a small business or even recommendation on your current business, I cannot recommend Will enough. Will is always getting informed in new laws as Taxes change which is super important nowadays.

I like how I'm able to scan and email (or in my case share a OneDrive folder) of the collected forms and W2s and he can take it from there. Invoicing is clear and straight forward with itemization, a bit more expensive than the HR Block I used to use but a lot more convenient and helpful from my viewpoint. You get what you pay for as the saying goes. Always fun and friendly to talk to and he helps to lay things out clearly and offers some great advice.

I made a tax appointment on April 1 for May 6. When I scheduled it, I told the office it was to…read moreprepare 2025 taxes for my mother and for a trust she has. When I arrived today, I met with a man named Oscar. I told him I was there to file taxes for my mother and for her trust. For some reason, Oscar asked me when my mother died -- she's still alive. Then he told me he couldn't do a trust return. When I asked why they'd booked an appointment for a trust return if they don't handle trust returns, Oscar blamed his assistant. This is despite the fact that "trust income tax preparation" is listed as a specialty on this very Yelp page. So now I have to start from scratch -- find a new tax professional and book another appointment, probably a month out. This is incredibly inconvenient, and it was easily avoidable. The worst part is that it's going to cost me real money. The delay between when the trust taxes should have been filed and when they actually will be filed is going to increase late payment fees and penalties. Will Robert Abbott Tax Services cover that cost? I left 1 star because 0 stars wasn't an option.​​​​​​​​​​​​​​​​
