Sierra Tax Service

I come here every year and Marco Sierra never fails to do a great job! Marco knows what he’s doing and gets you in and out as soon as possible. There’s always a crowd waiting when you walk in the door, so make sure to make an appointment and get there on time and you only wait a few minutes. Definitely my go to tax guy! Thanks Marco for all your help!

Sierra Tax Service is the way to go! A very welcoming atmosphere and I was greeted immediately when I walked in. I met with Ruby and she was super helpful in helping me with my taxes. I was totally clueless to completing my taxes and Ruby asked me a lot of questions and gave me a lot of useful information about filing my taxes (something that those DIY tax programs don’t do). It was a wonderful experience!

Sierra Tax Service has always been my go-​to place when it comes to getting my taxes done. It’s a family owned business and the moment i walk in, I’m greeted with a smile. They even all know me by name! I love the home-​feel of their office too!
Super quick, easy, and friendly.
Deff. recommend this to anyone.

It’s Tax season. Once again THANK YOU SIERRA TAX SERVICE. Simple the BEST. Professional, Friendly, Reliable. I know that I can go to
and schedule my own appointment with the staff of my choice. Get in and out with plenty of time to spare. I really enjoy coming here. Im confident of a good job well done. I recommend Sierra Tax Services. THANK YOU SIERRA’S each and every year

I’ve been coming here do get my taxes done ever since high school. I’ll make my appointment a few days ahead of time and it’s really simple. It’s really close to my house so that’s even better. I walk in and one of the ladies greets me and asks if I have an appointment. I only had to wait 30 seconds. I did my taxes with ruby. She is always really nice, friendly and accommodating. I had a couple questions and she answered them and that was that. This whole process took about 5 or 10 minutes. I got in, ruby helped me, and I got out. It was simple and friendly.
There’s always a ton of other tax places all over the city. But I don’t feel really comfortable with them cause it’s usually in a garage or someone’s living room. When I come here, I feel comfortable because they’re professionals.

I have been having my taxes done here for years. I started going to Marco on the recommendation of an old coworker. To be honest, I have always been treated differently at this office then the rest of the clientele. The staff, assuming I don’t understand Spanish, has made some derogatory remarks about me over the years. But as my visits were just once a year, I shrugged it off. Until two days ago when I made my annual visit. I called for an appointment and was told I had one at 11:30. I get there and by 12:30, not only have I not been seen but people who have come in after me are being serviced BEFORE me. I ask the gentleman (who has been speaking with me since I walked in the door) if he forgot about me, since I had an appointment, and I was promptly told «I don’t speak English». After finally getting the woman to get up and «help», all she proceeded to tell me was that I had made the mistake and not them and that it was only a walk in basis. She scheduled me an appointment for today, which I declined to go to.
I will never go back. I have never been treated so badly there before. They will survive without me. Lesson learned here: if you are white, don’t go there. They won’t treat you well.

Ive been coming here for years and years! Best tax services ever! They moved to a new location. Still in Pomona… very nice. Quick. Awesome staff always! Thank you Victor!

Awesome experience. Victor, along with his staff, are super friendly. You can tell this man really enjoys what he does and cares about his clients. I recommended him to my parents who waited until the last minute to get their taxes done this year but regardless, worked them into his schedule. There was an issue with my brothers college tuition forms and Victor went out of his way by working on a holiday to accommodate my parents making sure they had all the correct forms they needed. It’s a bit of a drive from where I live but definitely worth it!

I’ve been doing my taxes at Sierra Tax Service for 10 plus years. Excellent customer service and everyone is so friendly. I usually email all my information and I’ve never had a problem. Today was my 1^st time coming into the new location and it is very nice professional. I’m even recommending Sierra Tax Service to my girlfriend and her family. A plus service.

I’ve been coming here for 5 years now. I followed them from their old location on S. Park to here. I usually do my taxes with Victor (He’s on the bottom floor), he served in the National Guard so he knows what deductions as a service member I’m entitled to. It takes no more than a 20 minute sitdown with Victor (Unless it’s your first time, might take a little longer). I’m very pleased with the service, pricing, and experience I encounter everytime.
My father was seeking a new tax service, so I advised him to give this place a shot. Turns out (Victor found errors) for the past few years they have been cutting him short on his tax return from where he was going before. He will now receive a lump sum payment from the previous years. Way to go Victor!
I definitely recommend giving these guys and gals a shot.
Also, I would recommend calling as soon as you receive all tax related documents and make an appointment. They do welcome walk-​ins as well.
