I highly recommend XOA TAX for their unmatched expertise in tax preparation and bookkeeping. Their bookkeeping services have organized my finances, so tax time is easy. XOA TAX provides prompt, reliable customer service year-round, taking the stress out of tax season by expertly handling my return. Their professionalism and attention to detail is impressive.

I was impressed with the straightforward tax preparation service I received. Although my taxes are typically simple this year's situation was more complex than I could handle alone. I contacted Hoang and he responded very promptly. The cost was a bit higher than expected but ultimately worthwhile for the expertise and efficiency provided. I submitted all of my documentation and my taxes were completed just two weeks later. I knew I would owe taxes this year and was dreading the process so I'm grateful it was handled smoothly and quickly. Hoang also provided helpful suggestions for planning my tax payments next year. I don't live live in CA anymore but I will likely return to Hoang next tax season because I feel like I can trust him & his team.

I've used XOA TAX for taxes the past 2 years - they're awesome! Friendly, knowledgeable staff take the time to understand my complex tax situation with rental properties and multiple businesses. They ask tons of questions and always find extra deductions I miss, getting me max refunds. Before XOA, taxes were a pain. Now I look forward to my yearly appointment. Their reasonable fees reflect the personalized, caring service. Taxes are stress-free and enjoyable thanks to XOA's excellent service. I confidently recommend them to anyone seeking a trusted tax prep firm. Five stars!

Alhambra, Los Angeles, CA





XOA TAX has done an excellent job! I'm completely satisfied with the way they handled my tax return. I don't think my tax situation is complicated, but I appreciate the fluid communication with my preparer. He answered all my questions and took additional time to explain many tax "things" that I never had the knowledge of. And because of this new information, I will be able to plan out my 2021 taxes to maximize my refunds.
Definitely coming back next year!!
