They have been better. I think Covid times were challenging for them & us. But I can say they're better being responsive.

Julia has done my tax returns for many years and she was wonderful. Last year for some reason Kuan took over my tax return and he was terrible. So I will not go back to Trois. read more

I am a very loyal client. I have used Trois CPA for over 5 years now. The first 2 years, I was extremely pleased. Archie was on top of everything. The passed 3 years IN A ROW have been terrible experiences. I will not be using their services at all anymore. It took months to complete simple tax returns. Standard W2 returns. This passed year, it took 5 months just to get my husband's old 2019 returns filed. My husband begged me never to use Trois CPA again. This year, I ended up filling my own taxes using TurboTax for much less and I filed it immediately - not months later. As a loyal customer, I recommended Archie to my family as well. My cousin just learned that his 2019 return was NEVER filed although he paid them for services. One friend just complained that he's very disappointed in their slow services as well. Moving forward, we are all looking for new CPAs. read more

Always friendly and prompt response from this office. Archie is very professional and knowledgeable. Five stars.

Thank you Tracy for helping with my taxes this year, I highly recommend Tracy to anyone who is generally very clueless of what's going on. She was very thorough with explaining about what's going on. She had me bring in my previous year's taxes so she can show me the differences and we can compare. Appointment: must Parking: shared in a lot Price: reasonable Returning: yes, I will be back next year read more

They were good last 2 years that I've worked with them but this year I've been disappointed in their service. I've paid them on in early April before the deadline and then after a month later I found out that they did not even submitted my tax return to the government and now in June I am still waiting for my refund check. The reason they gave me was that Archie did not look over the tax return yet. It's unprofessional for their miscommunication and on top of that I am still waiting for my stimulus check. I could of received it earlier if they had filed my 2019 tax return in early April. read more

My siblings and I have been a customer for several years. Over the past two years, they have gotten so incredibly bad. They miss appointments, don't return calls, miss deadlines. It has been a nightmare. And they are not cheap either. It is unfortunate. For next year I am finding someone else. For this year, I will be hoping for a miracle that my calls/emails will finally be returned and my taxes filed on time. read more

I first found out about his office on yelp. I decided to give this play a try because H&R block was charging $150+ just for a person. Great CPA. Archie is a really nice and friendly guy. His office is a bit small and hard to find, but who cares the CPA was GREAT! Archie works with you and finds the best solutions for you to get as much money back as possible. For my mom and I our fee was only $90 and he finished our taxes in one day. Great and fast service, reasonable prices, very patient, explains things thoroughly and very professional. Next tax return I am so going back here. :) read more

This is my second year going to Tracy, and I won't be stopping any time soon. This year I brought my fiancé as well, and we are both extremely happy with her and the rest of the staff. Having previously done TurboTax or gone to H&R block and not been clear on what I was doing or why different factors contributed to the overall return, our experience at Trois was a shocking and refreshing change of pace (not to mention H&R charges an arm and a leg, while Trois is SUPER affordable). Tracy takes the time to explain EVERYTHING to you, and even show you if/then scenarios with your current return to illustrate what different effect factors have on your return amount. She was also able to offer us advice for our future decisions of claiming as either joint/individual based on past and present returns to help us understand what factors would change. Tracy spent as long as we needed with her, and went over past returns (pre-Trois) to make sure that we were not going to be liable for anything, and made adjustments accordingly. She was very friendly, and helped us feel comfortable knowing that she had a masterful understanding of tax law and was ensuring our maximum return while protecting us. All in all, I cannot recommend Tracy & Trois CPA highly enough. Extremely professional, courteous, and friendly service that has earned our business for years to come. Note- they moved to the location on Brea Canyon, but double check your directions if you look them up on Google; it may give you the correct written address but the wrong location on the map (their old office at Golden Springs). read more

Initially Archie was very good. Last three years, he would wait till the tax deadline to do my taxes. Very unnerving. Then to find out he did the taxes, but didn't file it. I called and couldn't speak to him. His secretary said the would take care of it. Two months later received another letter from IRS stating taxes were not filed. Again, can't speak to him. Had to go to another account to get it done. read more

Great service, but I had a brainfart and forgot to tell him my book and school expenses I incurred as a student (for a possible deduction in my taxes). Oh well my loss, he should have reminded me too, but oh well. It's done and submitted. Tricky to find, so when facing the building, he is on the second floor, on the westside (left side) of the building. read more

Been using Trois CPA tax services for about 4 years now for both my personal and business, Archie's services definite deserve more then 5 stars and no doubt my time for a over due review. He's great as ever, professional, easy to work with and very patient. He takes time on explaining and break down is very easy to understand. I only really communicate by emails and they are replied promptly, I never needed to call since I'm not in a big hurry for any answers. I had lots of new questions or even repeated questions whenever I show up to appointments, but Archie always answered them for me clearly and took his time, but I can definitely imagine can get busy! read more

Thank you Yelp for another great find! This time for my tax needs and can't say enough good things about Archie at Trois CPA. Super fast, efficient and knowledgeable. He spends a good amount of time to meet with you and understand your tax needs. He is very good with following up and replying to emails and phone calls as well especially since I had so many questions for him. I would highly recommend Trois CPA and Archie! read more

Yelp really came thru this time! True Diamond here! I had been searching since January for a new place to do my taxes. I got tired of my old tax preparer as every year it just got more and more expensive for an 1040EZ! Lucky Yelp came thru and I decided to try this place out. I called to set up and appointment and went in later that week. (I did my taxes in February so it wasn't as busy as say APRIL) I liked the convenience that its just down the street from work and how easy it was to get an appointment. It was easy to find and Archie was very friendly and detailed. He answered all my questions and gave me some good tips for next year.The whole process took less than an hr and I couldn't be happier! Even my dad is ditching his old tax prepare to come here! Thank you Archie, you did not disappoint! :) Note he also has an office in San Dimas (this is much closer to home, but Diamond Bar office was just more convenient at the time for me), hrs vary at this office as I think Archie mentioned he is only there in the mornings? Call and ask. But defiantly a MUST TRY for taxes. read more

Archie was great. He made doing my taxes an easy going experience. He is every knowledgable and honest. I highly recommend him to all my friends. read more

Beware! Do not go to this guy! We went to him a couple of years back for our 2015 income tax. A year later, i got a letter saying IRS and state did not get our file and our payment. Trois cpa gave us copies that they did file. How it happened? i do not know! They are very disorganized! To make matters worse, they did not even apologize for their mistake ! read more

If I could give a zero star I would. I had Archie take care of my taxes 3 times. First time was great, my taxes were simple and he finished my taxes pretty fast. The 2nd year he was fast, but I asked him via email a question, but he never never fully ever got back to my question. In for my 2015 taxes, I got married and had him do my taxes for me and my husband. My husband had documents he wanted Archie to include after our meeting, but Archie never attemped follow up on the update. My husband sent several followup emails and phone calls with no response. They cashed our check pretty fast though. I finally had to call their office and air my frustrations with them. They finally got back and finished our taxes right before the deadline. I was not very happy with Archie. The following year I got an IRS audit for an IRA conversion which I had asked Archie about in the 2nd year working with him. He said everything was okay o proceed tax wise and that there is nothing for him to do. But sure enough I got huge penalties for doing the conversion. Fortunately for us, my new CPA was able to rectify the situation and put an amendment to Archie's filing that year. Since Archie did not properly document I was converting my IRA. Very disappointed with Archie. Sure go ahead he can help with simple taxes, but anything more complicated good luck with that. Use him at ur own risk. Hopefully doesn't come back to haunt u like it did for me and my husband. Do yourself a favor and find a good CPA that actually knows what they are doing and knows the importance of responding in timely manner. read more

My wife and I have been using Archie two years in a row now and I must say he has been great. I'm surprised to read any negative reviews of him as I have always found him to be very responsive and attentive to detail. His pricing is very reasonable and he's just a nice guy. We know tax season is always busy for accountants which is why I suggest getting all your information ready to be submitted as early as possible. We always submit ours in the middle of February as soon as we receive all our tax forms as they get log-jammed in March and April. Anyways, I had a s-corp which I closed in 2013. I did the taxes myself through Intuit online payroll and Turbotax and filed my business and personal return incorrectly. It was a mess and difficult to understand and figure out with all the confusing IRS letters. I contacted Archie and he sorted through the mess quickly and explained to me what needed to be done and amended my return by the very next day. So bottom line go see Archie. My wife and I have been completely happy with his service and if you see him you will too. read more

Wow! Just got my refund back. Troi tended to all my needs and questions and everything done in a timely manner. It much faster than I expected. I'll never use turbo tax again. read more

They did not file our taxes MORE THAN 2 WEEKS LATER! I was waiting for our return & after 21 days, I called them to ask if they can find out any update but they never called me back. I gave them my name & phone. I called the IRS & was told that there has no submission for 2016 tax yet.....now thats when i became nervous that we just got scammed. i called trois 20x until someone finally answered & told them that i called IRS and they need to tell me whats going on, the girl on the phone checked our file & said the lady that did our tax didnt file it until just last weekend. thats just unacceptable. read more

I'm usually not one to write any reviews since I mainly use yelp to help me do some research on places to eat. Even then, seldomly do I ever write any reviews. With that being said, I had to write a review about this place since I feel that it is well-deserved. I usually do taxes on my own via turbotax, but since work has prompted me to work my life away, the little free time that I have is spent relaxing or hanging out with friends and family. Because of this, I started asking my friends and business associates of places that they felt were not just good, but great! I was a little hesitant at first since I discovered that Trois CPA hasn't been around all too long, but was assured that Archie, the owner, has been working as a CPA for quite some time. After meeting him and conversing with him, he was definitely someone I can trust to do my taxes. Working with him, he was very attentive to my tax form and asked very insightful questions that I never thought pertained to taxes. He had a high attention to explained things thoroughly and was very patient with any questions that I have had. In the end, he got me an amazing return that was much higher than anticipated and definitely more than any other years that I have done the taxes on my own. Definitely worth more than what he charges for his services and will recommend him to all my friends as I know they'll be in great hands! Thanks again and see you next year! read more

Been doing my taxes with them for 5+ years. Always professional and explains everything very thorough. Helped my husband with his business start up as well and how to file and make it an LLC also to transfer and change business names. FAST, Reliable and great customer service. I always recommend friends and family if they are looking. I've moved around and no matter where i move i still come out to diamond bar to get them done. read more

After holding three different jobs this past year, my taxes were all messed up and I was worried that I would end up owing money to the IRS for taxes. I can be quite a worry wart when it comes to things like this so I wanted to find the most knowledgeable and trustworthy CPA out there to help me with this important task. To prepare, I read up on tax brackets and deductions online and contemplated doing my own taxes through Turbo Tax. I was worried I would miss something and end up doing it incorrectly, so I started consulting friends and family on good CPA's in the area. My co-workers all go to a magician-like CPA who charges you thousands of dollars for taxes but will somehow get you a refund of thousands higher than other tax services. Although I was curious, I didn't want to lie and cheat on my taxes, and just wanted to find someone to answer all of my questions about how taxes work. I even made an appt and paid a visit to H&R Block for a tax consultation but the consultant there was vague and unhelpful. When I asked how to best optimize my situation for next year, she told me I would probably have to pay a lot of taxes next year and suggested buying a property or investing in an IRA. Is that the only way? Really? They also took a look at my W-2 forms and told me I would probably break even for the year. My consultation with Archie, however, was like a breath of fresh air. He was efficient, honest and straight to the point. He clarified a lot of myths I had heard and read about taxes, and also walked me through my entire tax form to show me which deductions are legit and can be applied, and which deductions I did not qualify for. He also explained everything in a "bottom-line" type of way that made it easy to understand and also gave me advice on what to do next year, which did not include rushing out to buy a property or open an IRA. He also told me that the people at H&R Block are not CPAs? That explains it then! By maximizing all of my possible deductions, Archie helped me complete my taxes with 100% honestly, and I am happy to share that I will be getting a few thousand back from the IRS this year. Yay! Archie charged me a very reasonable fee for tax preparation and handled the rest of my taxes electronically through email. This was super convenient because I didn't have to take another trip to physically sign any papers. Only thing was that it took about a week for him to reply to a question I had, but I understand because he's the main guy running the office and with tax season in full swing, I am sure he is swamped. Regardless, I still got my taxes done and it's only March 5th. QUICK TIP: The office is a bit hard to find. It's on the second level of the Tom N Tom Coffee Shop plaza, and joined with a Chinese Travel Agency office. Just peek through the window and Archie will come out to greet you. Thank you Archie for all of your help! See you next year! read more

I cannot say enough good things about Archie! He is such a customer service oriented professional! I have been working with him on my taxes which are very particular since I am in escrow on my dream home. He has been so kind and patient and helpful with helping me make necessary deduction changes that my lender has requested. If you are a self employed individual or a corporation, he is definitely the person you want to hire as your CPA! His fees are also very reasonable but after experiencing the great service he provides, the fees are the last thing I'm worried about! He is very knowledgeable and great with numbers. If you are looking for someone to do your corporate taxes or a crazy schedule C, he's your man! read more

Archie is very professional and knowledgeable. The staffs were friendly. Archie prepared my personal tax return. The process is very smooth and informative. He correct self prepared tax return with no cost. I would recommend him to my friends. read more

Archie with Trois CPA has been fantastic for me. He is so attentive to your needs and gives you his full attention. The CPA I worked with previously, I didn't even get to work with directly and only his staff. And they were not responsible with me and made many mistakes. Archie did a great job of undoing their mistakes and really spotting them out where I wasn't able to myself. You are in excellent hands with Archie Trois CPA! read more

Hard to reach Archie most of the time his assistant is the one returning your call. We first filled back March 2 and up to now we have not received our refund. When I call for update they request for forms to be emailed to them only for them to re request the forms back after weeks of delay. This is after u call repeatedly for update and no call back for days. I know it's tax season but if you need additional forms you would think they call right away so you can get them the forms they need to file your tax not weeks after when you assume everything is ok and filed. I went here based on the reviews but it was a big mistake!!! read more

I have nothing but good things to say about this company. Archie is amazing! Detailed and professional Ladies in the front was very helpful. Found a new accountant in the area and very happy with service! Keep it up! read more

Been going to Trois CPA for over 3 years now. I found Archie 3 years ago on Yelp like everyone else. His services through the years have been consistently good. Good CPAs are hard to find, and good ones are usually really busy. I do notice that Archie is getting busier and waiting sometimes is a must. I don't mind that though because there are many things to do at that plaza while waiting. I visit the coffee shop or grab some food sometimes during the wait. I would recommend anyone looking for a good CPA to go visit. Avoid the non busy CPAs, they are not busy for a reason. read more

Wow I can't believe I never yelp tax places before. Archie was fast simple got the point and was amazing. So happy I found a tax guy I can tell people about and go back next year!!! read more

Archie takes away all the intimidation associated with taxes. Not only is he exceptionally thorough with his work, he also provides practical tips so that you can further improve your taxation for the following year. I was very busy this year and couldn't make time to come in and see him. He graciously accepted all of my docs via email and handled my return in a timely fashion. I can't speak more highly of Trois CPA! Thank you, Archie. You have a forever client in me! read more

This was the first time we used a CPA in years so I wanted to be sure we chose wisely. Went on Yelp and found that Archie had fantastic reviews and I must say he did not disappoint. He walked us thru every detail and got us a good return and only charged us $80! We'd recommend him to a our friends. read more

Archie is very knowledgeable and helps with providing tax advise that is beneficial fir the growth of our business.

He was really easy to work with! Fixed all my tax problems. It was amazing. He helped me through it easily. And showed me what to do for the future. Must go! read more

It was time for a new CPA and I found Archie from a referral from a friend who had had a good experience filing her taxes with Archie. He's very knowledgeable. He does a great job explaining through the different items and how it affects me as an individual. I never knew or maybe never wanted to know some of the stuff on the filing but Archie made sure that I understood it and gave me tips for next year's filing so that I'm better prepared. Great CPA and definitely going back to him for 2014. read more

Archie is a very professional and knowledgeable CPA! We are so pleased with his efficient service! He is the best CPA we ever met! His knowledge and professionalism make him stands out from the rest of CPAs. He works with your situation and comes with solutions to get as much money back as possible. I highly recommend Trios! Don't let tax stress you out! Let Trois handle it, saves you time and money!! read more

I found Trois CPA through yelp (thank you yelpers!) and I couldn't be happier with my experience. I have gone through several job changes and recently switched to a 1099 position and he was really helpful and even offered to set up a meeting with me to discuss everything in person. Email is probably the easiest way to contact Archie and he is always very responsive when I write. I will definitely be back next time taxes are due! read more

Thank you yelp for helping us find Archie. For years we have been going to taxs companies who couldnt even answer our questions. im the type of person who askes alot of questions because i want to get back the max refund, but i never get clear answers until today. Archie was so helpful and answered all of our questions with examples. He made taxes understandable. i took my taxes to another place and had them done but not field, then went to Archie and had him run my numbers and he was able to get me 400 more then the other place. i was so happy! we will for sure be back next year and recommend Archie to all our friends and family. read more

This is a long over due review. I have had dealt with 5 different CPAs in the past 15 years from filing personal, business taxes to setting up corporations, and LLC. None of them can stack up to Archie. He is patient, and knowledgeable with every question and business needs I have. This is a breath of fresh air of dealing with a CPA, and I am extremely glad to have trusted the prior Yelp reviews. Taxes can be stressful but Archie definitely alleviated a majority of that stress so it allows me to focus on my business. I will absolutely recommend Archie to my personal and professional acquaintances. read more

Archie took care of my whole family's taxes including my parents' taxes. He is great to work with, very friendly, and has great rates. I can't say enough good things about him, other than you need to make an appointment significantly in advance to see him in the busy part of tax season. For him, that is the end of Feb to April. read more
