Customer Reviews

Let me start by saying I haven't filed taxes since 2023! The last tax preparer I was recommended to made things so difficult and expensive to file. Plus I never met them in person, never trusted giving out my information to anybody. I was so ready to get my taxes done. I definitely would recommend people to come file with Oak Tree. It was so easy for me to call and set up an in person appointment. Melissa is more than great she is the G.O.A.T!! The environment was clean, conversation was great, all while

Relocating to a new city, I was initially apprehensive about selecting the right tax service provider. However, Oak Tree Service quickly alleviated those concerns. My first experience was exceptional, marked by a warm and welcoming atmosphere. They asked insightful questions to ensure accuracy, making the process efficient and enjoyable. I even appreciated the light-hearted banter while my files were being processed. This positive experience guarantees that I will return year after year.

I have used Oak Tree Services for years, and they are the best, they really helped me when I transitions to a new career where my income increased significantly. Melissa walked me through everything and made sure I did everything correctly, she is the best. Highly recommend.

My husband and I trust no other organization with our tax preparation. The members Oak Tree Services are professional and knowledgeable in what that they do. Melissa is our go to gal. She ensures all of our many questions are answered and goes above and beyond to assist. Oak Tree Services makes tax season a better season.

I've never filed taxes before and was unsure how this would be but from the easy to navigate personal portal system to the kindness felt over the phone during conversation this was one of the easiest things I ever done. Top tier professionals! Ms. Melissa not only did everything to get me the most on my return she could, I honestly was not expecting to get what she was able to get me. I know for certain who I'm sticking with for now on for my taxes.

Very pleased with the services Melissa and the rest of the team at Oaktree services provide. They're always ready to answer all of my questions and make any process such a breeze! Thanks for all you do!!

Prepared to end a cycle of frustration. Totally relieved by just 1 phone call. Soon will definitely have Oak Tree resolve my Tax issues. Thank You

Oak Tree Services is one of the most professional, informed and efficient services I have ever work with.

Very Unprofessional. I set up two appointments with Melissa and she canceled on me twice right before my appointment with her. The first time she asked me to reschedule for another day which was fine and rescheduled for another time. It is understandable things come up, but then on the day of the rescheduled appointment she calls me half an hour before my appointment and cancels it. I am sorry for the one star, but I was disappointed without receiving a service.

I was referred by my coworker and the service rendered was detailed and swift. I did not need to come in, all virtual and worth it. Refund received within a week. Melissa is professional! Thank you.

Melissa and her team have been amazing in the tax filing process for me and my family the past 3 years. I'm so pleased with my outcome every time ! Thank you Oak Tree!

What's your peace of mind worth? For me, having my taxes done by Oak Tree is a simple no-brainer as it's one less thing to worry about and its something i know will be done right! As a young man, I used to complete the 1040 EZ form myself. Now, having secured some property and a higher overall income, it pays to have a professional servicing my interests, especially in an environment in which already complicated tax-related laws change often. In addition to the yearly service, Melissa and the team sends

I absolutely love this team. I have been going to Oaktree for years and they have always taken such good care of me. When you're a young professional, it can be intimidating to dive into your financials, especially when it comes to taxes. But working with Oaktree has made me confident with tackling this necessary to do every year (yes it's necessary to handle your taxes if you want to avoid serious problems with the IRS). They understand every customer's individual issues and concerns and they make sure to

Finally a professional platform that is about business. Where the client comes first and is patient with me. The turn around time is amazing and explanation of anything I inquired was clear as day. If you are looking for a place to stay long term that will stay loyal to your needs, then Oak Tree Services is right for you.

I was recommended this company from a friend 5 years ago and have never once regretted it. Amazing service, and ease of use with their portal. I refuse to do service with any other company for my tax services.

I have been with Oak Tree for over 20 years. I only trust them and will always work with them! They're honest and loyal and such wonderful people.

Frequently Asked Questions

What qualifications should I look for in a CPA?

Look for a Certified Public Accountant (CPA) license, which ensures they’ve passed rigorous exams and meet state requirements. Check for relevant experience in your industry, additional certifications like CFA or CMA, and membership in professional organizations like the AICPA. Verify their credentials through state licensing boards.

How do I find a CPA in my area?

Use online directories like the AICPA, CPAverify, or state CPA societies. Search platforms like Yelp or Google for local CPAs with reviews. Ask for referrals from business associates, friends, or financial advisors. Local chambers of commerce can also provide recommendations.

What’s the difference between a CPA and an accountant?

A CPA is a licensed professional who has passed the CPA exam and met state requirements for education and experience. An accountant may lack this certification and could have varying levels of expertise. For complex tasks like tax audits or financial reporting, a CPA is typically more qualified.

How do I know if a CPA specializes in my needs?

Ask about their experience with your specific financial needs, such as tax preparation, small business accounting, or estate planning. Review their website or LinkedIn for case studies or client testimonials. Inquire about their client base to ensure they handle similar financial situations.

Should I check a CPA’s reviews before hiring?

Yes, reviews provide insight into a CPA’s reliability, communication, and performance. Check platforms like Google, Yelp, or the Better Business Bureau for client feedback. Look for patterns in reviews, but verify their authenticity, as some may be biased or outdated.

How can I verify a CPA’s license?

Visit your state’s Board of Accountancy website or use CPAverify.org to check a CPA’s license status. Confirm their license is active and check for any disciplinary actions or complaints. This ensures they’re in good standing and meet professional standards.

What questions should I ask during a CPA consultation?

Ask about their experience with your financial needs, fee structure, availability, and communication style. Inquire how they handle tax filings, audits, or financial planning. Ask for references or examples of similar work to assess their expertise and fit.

How much should I expect to pay for a CPA’s services?

Fees vary based on location, services, and complexity. Basic tax preparation may cost $150-$500, while business accounting or audits can range from $1,000 to $10,000+. Request a detailed fee structure upfront and compare quotes from multiple CPAs.

Can I work with a CPA remotely?

Yes, many CPAs offer remote services through secure online platforms for document sharing and virtual consultations. Ensure they use encrypted tools for data security. Remote CPAs can be effective if they understand your local tax laws or business regulations.

How do I assess a CPA’s communication skills?

During consultations, evaluate their ability to explain complex financial concepts clearly. Ask sample questions about taxes or financial strategies and note their responsiveness and clarity. Good communication ensures you understand their advice and fosters a productive relationship.

What red flags should I watch for when screening a CPA?

Beware of CPAs who guarantee specific tax refunds, lack a valid license, or have disciplinary actions on record. Avoid those with poor communication, vague fee structures, or negative reviews highlighting unethical behavior. Always verify their credentials independently.

Should I choose a CPA from a large firm or a solo practitioner?

Large firms offer more resources and specialized teams but may charge higher fees. Solo practitioners often provide personalized service and lower costs but may have limited availability. Choose based on your needs, budget, and preference for personalized attention.

How often should I meet with my CPA?

For individuals, annual meetings for tax preparation may suffice. Businesses may need quarterly or monthly check-ins for bookkeeping, tax planning, or financial reporting. Discuss your needs upfront to establish a meeting schedule that aligns with your financial goals.

Can a CPA help with both personal and business finances?

Yes, many CPAs handle both, but confirm their expertise in both areas. Ask about their experience managing personal taxes and business accounting simultaneously. Ensure they can balance both without compromising attention to your specific financial needs.

What should I do if I’m not satisfied with my CPA?

Discuss concerns directly with your CPA to resolve issues. If unresolved, check your contract for termination terms. Seek a new CPA by researching reviews, credentials, and referrals. Request your financial records to ensure a smooth transition to a new professional.
