He is worth every penny and then so

After many years of using another tax professional, we felt it was time to make a change. So three years ago, we made the change and started using Jeff at Mt. Diablo Tax Pros. Since we own a business, he prepares our Corporate Returns, as well as our Personal Returns. He is diligent in making sure he asks questions that might uncover additional deductions. And, when questions have come up, after filing, he is there to help us understand what needs to be done in order to resolve them. He also advises us

I have been seeing Jeff Rondini for many years. My whole family see's him as well. Jeff is very professional and it is clear to me that he always has my best interests in mind. He is knowledgeable and I trust him to do my taxes because I know it will be done correctly. I actually really enjoy having Jeff do my taxes because it's like meeting up with a good friend and catching up on what has happened in the past year. Go see Jeff Rondini, you will be happy you did!

I have worked with a few other accountants through the years. Jeff by far is the most responsive and is diligent in understanding all of the details that go with filing.

I highly recommend working with him. I appreciate that he is available and doesn't leave me without answers. It helps with the stress that comes with taxes

Great communication , very timely, a real professional , and a hell of a nice guy. Looking forward to doing business with Jeffrey agian, soon.

I made an appointment to ask some questions about filing my taxes and about my deceased father's taxes. Jeff was very knowledgeable, forthcoming and completely honest.

I needed help with my taxes that TurboTax couldn't provide, so I got in touch with Jeff. He was able to fit me in around a full schedule, and take care of my return in under an hour. Highly recommend!

New to Concord and went on to Yelp. Found Mt Diablo Tax Pros and read all the reviews. The one that convinced me to give Jeffery a shot was when one gentlemen asked for a quote at 1:30 in the AM and was upset they he did not hear back until 6:00 AM the next day.... He then proceeded to post of screen shot of their correspondence. Jeffery responded in short it's very difficult to give you an accurate estimate since you have not told me any info about your situation, how many w2's are you single, IRA's, do

Jeff by far is the best tax preparer ive been to. He explained every paperwork filed and is very professional and knowledgeable. I would recommend him to any one looking to get their income tax paperwork filed correctly.

This is my 2nd year with Jeff, and I am as impressed this year as I was last. He responds quickly, answers questions throughly, and assures you of the right choices to take when filing taxes. One painless appointment and your taxes are filed quickly and precisely. I appreciate his advise and support!

After reading Jeff's stellar reviews we decided to give him a shot and so glad we did! Great to work with, highly recommend.

I would use them as subcontracotrs.

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.
