Customer Reviews

Sean has been a lifesaver for me in terms of answering my complicated tax questions, preparing Quickbooks entries in order to get caught up for tax time and being a trusted advisor. I recommend MPN wholeheartedly. Sean is extremely knowledgeable and is an invaluable partner to help your business stay on top of routine bookkeeping and preparing for tax time. He has helped me with issues with old Quickbooks Desktop and I will be using him soon to transition to Quickbooks online.

Sean Pendergast and his firm blew the big chains out of the water. Don't get me started on turbo tax. H&R Block did okay last year but this year with Sean and his firm went above and beyond to get me the most on my return.

I used to do my own taxes for years until I met Sean! I have not looked back ever since and will never attempt to diy it ever again. Sean is a pleasure to work with.

I'm really grateful for his help and expertise and confidently recommend Sean to friends, family, colleagues and clients.

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.
