Greg is very through and knowledgeable. Easy to work with! Would highly recommend. Is just what we were looking for after we moved to AZ.

Greg is one of the smartest, kind people you will ever meet!Absolutely understands the tax code better than the people at the IRS., my opinion. You definitely want him and his team on your side. read more

Have been going to Greg for maybe 5+ years and referred a few friends. I trust him. He has done not only taxes but given advice on how to manage licenses and financials for our business. read more

Greg is very precise with his work and my husband and I like that he makes sure that we cover everything before completing our meeting. They are honest and friendly at Greg's Tax Service and my husband and I feel like get the best service there. Thank you Greg and Greg's Tax Service! read more

Ca cost of living is 30% more then Arizona. Greg moves to Arizona and raises prices 80%. What a slap in our faces. I'd rather give my business to somebody local. Let the Arizonans pay those prices. Besides his new prices Greg is excellent. read more

First time using this tax service. I was impressed how detailed and thorough the staff is. They kept us updated throughout the process. Greg found deductions we wouldn't have thought of. I would highly recommend this company. The price was very reasonable. You will not be disappointed. read more

If I could give negative stars I would. He ruined our returns for years and made a rather big error last year delaying our return for months. When it was brought to his attention he forced us to correct the issue ourselves and was extremely unprofessional as well as out right rude. I had our taxes done by someone else this year who was wonderful at which time she told me that he did not file with any of our 4 dependents last year. Our return should have been thousands of dollars more. I only suggest Greg if you are a fan of throwing your hard earned money directly down the toilet. If you're currently a client I highly suggest having your past returns reviewed elsewhere and if you are a prospective client... DON'T DO IT! read more

Hands down the best tax experience I have ever experienced. My co-worker recommended him to me and after the experience I must write a review for Greg. I have had 2 different CPAs or tax consultants in the past 8 years. My philosophy has always been why do my own taxes when there are professionals that know how to do it better than me. Well the past 2 tax consultants made my life more difficult, provided no guidance and were not efficient. After working with Greg I finally feel like tax season isn't going to be something I dread as much (at then end of the day it is still tax season). I did everything over the phone and email with him as I live far from his office. Everything ran smoothly as Greg has a secure system to upload all documents. His communication was efficient and to the point and he actually got me a tax return! I know this may not happen every year, but I have not gotten a return in years because I have complicated tax issues. With Greg things did not feel complicated this year at all rather he accomplished my goal of making my life easier. I highly recommend Greg for all of your tax needs read more

Been going to Greg's tax service for years and so has my entire family but i will not be returning. He sent out a letter stating he is charging the same fees for everyone even if you been with him since day one. This is when he did it out of his house which shows no loyalty on his end. He charges $195 for a long form and has his girlfriend who constantly needs to call him in for help doing the taxes as well. We received no instructions on what to bring even though when we called we let them know we were first time home buyers. The day after our tax appointment we got something in the mail for our interests so i called and left a voicemail for a call back. Someone texted me asking me to send over the information (not very professional). I sent it over and they texted back saying what we would get back we would end up owing them to fix it so not worth it to fix and that it's not their fault that it came after our appointment and they didn't know we needed it. I said i would think someone who has been in the buisness for 25yrs would know that if it is a write off to ask for it. They respond back in a text message to not be rude to them. Even during my tax appointment his gf said she should have let us know what we needed. I am loyal to the places i give my business to but not when they are not loyal back. He is clearly greedy when he won't fix something on taxes for someone who has shown loyality to him and gave him other customers! He has always complained about his marriage for hours, how his wife is pathetic and so on. I come here once a year for my taxes not a counseling session but it's time to take my buisness somewhere else. read more

My wife and I have had our taxes done by someone in Los Angeles where we used to live and every year we owed money. This year it came back huge. We owed over $8,000 in taxes! We were floored and asked the tax person to file an extension till we could figure this out. We decided that maybe another tax person could help. So I looked for a local tax preparer in Antioch and came across Greg's Tax Service. He had some good reviews so we gave him a chance. He was willing to stay open late since my wife doesn't get home till late from work. Then he walked us through where the other tax preparer left out items we could deduct. Greg saved us nearly $5,000!!! We're bringing our past taxes in for Greg to review and it's well worth the cost. This guy knows his business and I highly recommend him. Nice office with a few toys to keep the kids busy,too! Thank you Greg we ate your newest forever clients. Cheers! read more

No need for a long review. He was referred to me by a friend. He proved to be the best. He anticipated what his clients require and the price is reasonable. read more

Greg is fantastic! He is super helpful and very sufficient. He takes his time explaining things to you if you don't understand. My wife were behind on our taxes from last year and he explained what everything meant and how he could help us. I will be recommending him to other people and going back to him for many years to come. read more

I have used the services of Greg for my taxes twice and he never disappoint.Greg is so knowledgeable that he did a great job doing our taxes this year with a return that we could hardly believe.If you need an honest,knowledgeable tax preparer then,you don't need to look elsewhere.This is a man of high integrity and by the way his new office address is 3721 Sunset Ln,suite 103 Antioch. Keep up the good work Greg! John Tanwani. read more

Greg is very knowledgable and a really down to earth guy. I have used him the last two years and I am really happy with his service. I like that I can ask him anything about anything! He gives great advice and I really trust him! read more

I was referred by a friend to see Greg. I was very happy with the results. He was knowledgable, friendly, sincere and honest. He also gave me tax tips for the following year! He is also affordable!!!! I'm definitely coming back! read more

Greg's tax service is great! I am a new business owner and have been using Greg for a year now and he has answered multiple questions I had for no charge. His rates are very fair. He takes the time to sit with you and explain things until you understand them. Overall great experience! Thanks Greg! read more

Had been going to Greg for years, and even referred numerous other clients. Over the years, I heard grumblings from other clients about how rude he was. I initially dismissed those claims until unfortunately having my own negative experience with him. Sad to say, as his business grew, so did his ego. The level of disrespect displayed by him was appalling. Greg is extremely rude, condescending, and unprofessional in his exchanges with his clients. I will certainly NOT be returning. read more

I met Greg for the first time yesterday and my first impression was that he was super knowledgeable of tax law. My tax stuff was a little bit more complex since I had a K1, a bunch of "work-from-home" expenses, and both me and my wife's w2's. He was able to squeeze out as much deductions we were qualified for and even taught me some new things that I didn't know were deductible. He is very affordable! On his website he offer's a $20 first time client discount and he even offers additional $20 discounts for every referral you send him. He had our taxes done in no time and I am very pleased with his services. I recommend him to EVERYONE! He is my new Go-To tax person in the East Bay. Go GREG! read more

no nonsense, easy to deal with, honest, fast and reasonably priced. What more do you need. We will be repeat customers for sure.

Greg help get our taxes done this year in a timely fashion. He was fast, friendly and reasonably priced. I will be back next year! read more

Greg is the most honest, most hard working, and most specialized tax services professional! I have been going to him for nearly 10 years and i highly recommend him to anyone who needs tax services! He is a straight shooter and very knowledgeable! read more

Had an opportunity to work with Greg, great guy! Runs an efficient and clean office. Great location too with easy parking.

Kim actually helped us at Greg's Tax services and did an AWESOME job. She was very friendly and explained a lot of our tax process as we went along. We are ecstatic that we have found a tax service close to home and at a very reasonable price. I would 100% recommend Kim at Greg's Tax services. read more

Greg has been doing my taxes for a few years and when I needed assistance with an Offer In Compromise he was on it! He was very knowledgeable and had handled many of these types of dealings before. Greg broke down the process for me and it went just as he had described. My offer was accepted and that monkey is off my back!! Thank you Greg!! read more

Hello Christina G. This is Carol. I prepared your taxes this year. I find your comments about us completely false and just plain mean. I never said to you that I should've let you know what you needed to bring. Having been a client of Greg's for so long, I know you are aware that we send out multiple reminders and checklists of what you need to bring. We also have a very detailed website at your fingertips. I have been given a wonderful opportunity to learn this business from someone of Greg's caliber. He comes over to my office because he reviews (in detail) every return that goes out of his office. This is not just a place he works. He pours his heart and soul into his business. His clients are family to him. He is very open, but is also professional. He gets to know his clients on a personal basis. For you to post very private things that he has shared with you, shows your character not his. I do agree with you on only one thing. You do need to take your business somewhere else. We are a very loyal, hard working family here at Greg's Tax Service. read more

This guy is good,I had a tax issue with the state that I had been fighting for over 6 years.I have hired 2 cpa's key tax group out of florida who was recomended to me by optima tax relief.They ripped me off for 2500.00.Then I hired stop irs.gov who got me for 4500.00 and jerked me around for a year.Finally just out of luck I found greg,he had my problem fixed in less than a week and only billed me 650.00.These so called tax relief places are crooks they get your money up front and win loose or draw its gone. read more

Greg is fantastic! He is super helpful and very sufficient. He takes his time explaining things to you if you don't understand. My husband and I got married last year and had a rental property and bought a house and he explained what everything meant and what it did to help us. I will be recommending him to other people and going back to him for many years to come. read more

I discovered Greg on yelp and saw all the high reviews he received and was in desperate need of some help w/ our taxes. His fee was so reasonable and for new clients there was a $20 discount. His assistant Karen met us in the evening at 7pm to go over our taxes with us that had us so confused and worried. She took the time to go through them and with such a great sense of humor to lighten the mood. Greg then also came into her office that night to introduce himself and go through our taxes with us to make sure we were choosing the best option for filing. They spent a whole hour with us and due to our situation it was best to file through turbo tax as I had originally started with since we were going to owe $. Greg suggested we continue with turbo tax in a way that he described to us to make sure we didn't owe as much and so that we also wouldn't have to pay a fee to file through him since it would be more of a out of pocket expense to add to what we were already going to owe. I was so grateful for the both of them taking their time with us, being patient and doing all that they could to help us even if it was just advice. I know that Greg's time is valuable and was fully booked for this month, but he still gave his time and attention to us. I plan on referring him to everyone I know. It's rare to receive the high level of care and customer service we received from Greg and his entire office. We will be using his services in the future. Thank you Greg & Karen!!! YOU GUYS ROCK!!! read more

Used "Gregs Tax Service" this accountant for years to do my taxes but had a very bad experience this year when filing for my 2016 taxes. Had my appointment. He made me feel rushed and was not very helpful as he usually was before in the past and acted as if he was in a hurry to file my taxes and move on to the next appointment during my appointment. Usually an appointment last about an hour or so but he pushed me out within 30 minutes like he was in a hurry wanted to get paid and that My appointment did not matter which is unacceptable. He "Greg" had an attitude and said I should feel happy and be grateful that I made what I made for that year. What kind of accountant acts bitter like that. He behaved with an unprofessional attitude with me which I can't believe because I used his services for about 7 years and always paid him promptly up front no question! Asked him a question by phone and was hoping that he could explain it to me in person. I asked this same question during my appointment and he asked me to put together my receipts and then call him back. He had nothing but a bad attitude that showed anger and unprofessional frustration. He also left a very mean and unprofessional voice message on a return call. He must be having an issue but that should not constitute treating a return customer who has paid for your services each time for about 7 years now. Will definitely not be using his services anymore. Beware.!!! You should always use an accountant who acts the utmost professional that makes you feel like your appointment and time matter when you are paying for their services especially on a yearly basis.. read more

I also have been using Greg's tax service for years (like Christina G), going on my 2nd decade as a matter of fact. As of yesterday I ended my relationship with him. It's not the fact that he cancelled our Monday appointment (3-12-18) due to a family emergency, totally understandable. When we went to drop off the our tax info on that day about 30 minutes after our appointment was to begin, he was in his office, looked at us and immediately shut the door, without saying hello. Totally unprofessional to say the least, but that's not my issue with him. I had no problem going from $125 to $195 for our simple taxes. However, my wife has a dormant business and does a little light housekeeping for a friend every other Friday. My wife's situation hasn't changed in the last 5 years. I went to pay the bill in his office and also pick up my taxes on (3-21-18), the invoice wasn't ready according to the receptionist, I spoke to the receptionist on the morning of (3-21-18), you would think that that would be enough notice to have it ready by the afternoon, again very unprofessional. I got the bill for $275, and asked why is it more that $195, she didn't know, had to text Greg, first to create the invoice, then text again to arelay my questions. The response was that for my wife he had to do an additional form, thus the additional fee. I know for a fact that the information on my wife's tax info was already in my computer, and he I'm sure it was a cut and paste type of thing for him for this years taxes. He wasted 30 minutes of my tiime yesterday, I should fill out a form and bill him!!!!! The point being: He has no respect for long term relationships and his love of the all-mighty dollar is shining thru... I have given him a couple referrals throughout the years, they have referred, and those folks have referred, like compound interest. I will be spreading the word that Greg has no respect for long term relationships starting with my neighbors, ex-neighbors, friends and he will see the "trickle down" effect next tax season. His reply in his email to me last night was that I could find a "cheaper tax preparer". It's not about the $$, it's about his disrespect for long term clients. I look forward to establishing a relationship with another tax preparer who respects long term clients... read more
