BASC Expertise

Thankful to have found this company to do our complicated taxes and always available to answer our questions. We appreciate their consulting services!

I contacted BASC Enterprise and advised that I would need an extention for this year. They immediately took action and within minutes advised that my extention would be filled. Much appreciated, quick and painless. Thank you BASC.

I have been with BASC expertise for almost 3 years…since they took over for Joanne McConnell. I was a bit leery since I am an expat and Joanne knew my situation very well. I have been very pleased with BASC’s services. Whenever I’ve had a question or issue, Deirdre and Kristen have responded or dealt with the situation promptly. I highly recommend BASC expertise for doing your taxes!!

BASC Expertise exceeded our expectations. We have had many years of experience with a large national accounting firm followed by a small CPA firm. BASC is the BEST.
Specifically, I liked 1) the automated workbook, 2) the responsiveness of all of the BASC personnel.

I will be recommending BASC to others.

We used BASC for the first time this year, and were very happy with their service.

Exceptional, Proactive Year-Round Support with No Surprises.
I highly recommend the team at BASC Expertise. As a small business owner in Scottsdale, I value strong partnerships, and BASC has been a breath of fresh air. I switched to them after a frustrating experience with a firm that lacked follow-up and proactive tax advice; the difference has been a total 180.
We are now in our second year with them. They consistently complete our taxes early with all costs known upfront. What I really appreciate is the option to oversee our financials each month and provide feedback to avoid unwelcome tax surprises at year-end. As a professional, I highly recommend having a proactive team in your corner, and BASC has been an ideal choice for my small business.

Deirdre at BASC is knowledgeable, efficient and friendly. It's challenging to find a skilled tax preparer familiar with non-profit filings. We’re so grateful we found them.

This team is very detailed and timely! They are experts in their field. Kristen has guided me with starting our business and have transitioned smoothly. The website is user friendly and you can request appointments on their portal.

Deirdre and her team at BASC Expertise are very professional, I have been using their services for 3 years and never had any issues. Great communication, prompt response when there's any questions all my returns and documents are always on time. Our tax returns for business and personal are stress free.

The best tax partners a gal could ask for me.

BASC prepared 2 tax returns for me; a personal return and another for a trust for which I am the executor. In both cases, the team at BASC were throughly knowledgable. When I had questions (and I had many) they responded promptly with answers that helped me move confidently through the process. Since I had never been executor for a trust before I greatly appreciated their patience and expertise. I filed my taxes feeling confident that they had been correctly prepared.

Personal experience with BASC for 4 years. Deirdra has always been open, honest and up front and fair with every aspect of working with her company. Her and Kristen have always been readily available with any questions and concerns we’ve ever had. She has taken on the load we don’t have the time to carry. Deirdra has gone above and beyond for me in the tax and legal aspect of my business. You get exactly what you pay for with a tax professional, if you can’t afford top tier service from a company like BASC, it doesn’t justify a bad review out of spite. Not once have we ever had an issue with contracts, agreements or access to accounts. Just because you can’t fulfill contractual obligations doesn’t justify slandering a company. I 100% appreciate all the hard work her company has done for me.

I’ve been using BASC for the past 4 years and I would never trust anyone else with my taxes and bookkeeping for my businesses. Deidre and Kristen are simply the best, extremely knowledgeable, friendly, and communicative. These lady’s have saved me tens of thousands of dollars in taxes and make my life worry free from the IRS.

Fast and efficient, answered my questions immediately, and got my taxes sorted painlessly.

Updating my review because of bad actors that don't have any idea what is going on and how compliance works.
I recently had the pleasure of working with Deidre and BASC Expertise, and I cannot express enough how impressed I am with their professionalism, knowledge, and dedication to their clients. From start to finish, Deidre and her team provided exceptional service and expertise.

Their attention to detail and commitment to understanding my needs truly set them apart. Deidre took the time to listen carefully to my concerns and provided insightful solutions tailored to my specific situation. Her depth of knowledge in the field was evident, and her ability to communicate complex concepts in a clear and concise manner was remarkable. Highly recommend their services for your personal or company taxes.

They do a fine job.

Grace Strongly Recommends BASC Expertise

I had a tricky, nearly last minute trust return that needed attention.
Deidre at BASC was willing to tackle the issue and completed the necessary filing's efficiently. I’m grateful for the professional support I received.

Deirdre and her team at BASC are truly extraordinary to work with. Deirdre goes above and beyond to help her clients and is always there to help with understanding so that you do not feel like you are being left in the dark about any step! I truly appreciate their communication and dedication to their clients. Their level of commitment is unmatched and I would recommend them to anyone who crosses my path!

Work and response were done in a timely manner, however, the work although thorough should be carefully checked. I found an error in the first draft that required and received a correction.

Working with BASC has been a game changer. Their service is unmatched — always available, responsive, and willing to go the extra mile. I’ve worked with top 5 CPA firms before, and I can confidently say that Deirdre and BASC deliver the same caliber of expertise and professionalism at a fraction of the cost.

What truly sets them apart is their accessibility. They answer calls, messages, and questions 24/7 — something unheard of in the industry. Beyond handling accounting, they anticipate needs, provide strategic insights, and make complex financial matters simple and actionable.

If you’re looking for world-class accounting support without the inflated price tag, BASC is NEXT LEVEL.

We couldn’t be more grateful for the incredible support and expertise we received from BASC! We came to them overwhelmed with taxes, a messy company structure, and more questions than answers.

They quickly took control of our tax and filing issues, guiding us through every step of the process. Their strategic advice on restructuring our company was amazing — not only did they streamline our operations, but they also uncovered significant savings opportunities that we never knew existed.

Thanks to their work, we’ve saved a substantial amount of money and now have a much stronger financial foundation for growth.

Couldn’t recommend them enough

The folks at BASC Expertise were super helpful and also super FAST. We were in a bit of a bind with our taxes and they got us sorted very quickly, while also helping us better understand our tax situation.

Deirdre and Kristen we're amazing to work with! We had many questions about our LLC and they they answered everything and got our LLC returns done within less than a week! Highly recommend using them for your business and/or personal taxes!

BASC has been very helpful in getting my business back on track and I cannot thank them enough for taking the stress away. I feel confident moving forward that I will make better decisions because of them. Thank you and look forward to continuing our relationship. Thank you, especially, to Deirdre!
