ZMC & Associates LLC has been such a great assistance in growing my business. They have not only assisted me with accounting services but has offered business consultation on how to boost productivity and profit for my business. Before consulting with ZMC & Associates LLC, I had little knowledge on payroll, bookkeeping and business taxes.

The staff maintains the highest degree of integrity and professionalism when serving you. I highly recommend ZMC & Associates LLC to any business owner seeking a reputable business with a personalized approach to helping their clients maintain business profitability and to stay in compliance.
Unified Counseling, Snellville, GA
DACA was having a difficult time finding someone who was willing to assist us with registering our group as a nonprofit. Finally someone referred us to ZMC & Associates LLC. In a very short time Mrs. Cazaubon convened a meeting with our executive. She presented a very detailed account of the procedures and the requirements for applying for 501 status. She discharged her duties professionally, was very organized and efficient and kept us abreast of the process. She gave us a time frame as to when we would receive our tax exempt status. She was on target. Mrs. Cazaubon is a very pleasant, trustworthy and outgoing individual. DACA is pleased with her performance. We will continue to engage ZMC to assist us with our tax and accounting issues. We strongly recommend ZMC to individuals and groups who would like to utilize her services.

I have been using ZMC Accounting for their tax services for several years. The process is always quick and convenient and I am always happy with the end result. The best part is I never have to step foot into an office or fill out any tedious forms. I even received assistance with my annual FAFSA form I needed to file out while in college. When I receive exceptional service I am usually a customer for life. I also will refer my family and friends. I love to rave about ZMC Accounting especially during tax season when people are frantically gathering their tax documents and dreading the tax return process. For me it's a quick and simple process from the time I submit my documents to the time I get my money directly deposited in my account.

Frequently Asked Questions
Tax audit defense involves professional representation and support to navigate audits or notices from tax authorities. Our team helps you understand the scope of the audit, gather necessary documentation, communicate with the IRS or state agency on your behalf, and work toward a resolution that minimizes additional taxes, penalties, and interest. Engaging experienced experts ensures your rights are protected and reduces stress during what can be a complex process.
We begin by reviewing the notice or audit correspondence, analyzing your financial records, and developing a tailored strategy. Our professionals gather and organize the required documentation, communicate with the IRS or state agency to clarify the issues, and represent you during meetings or hearings. Throughout the process, we negotiate to reduce liabilities and penalties, keep you informed of progress, and implement any necessary changes to your filings. Once the audit is resolved, we provide guidance to prevent future issues and maintain compliance.
We can assist with a wide range of tax issues, including federal and state income tax audits, payroll tax audits, sales tax audits, and notices from the IRS or state authorities. Our team helps address unfiled returns, disputes over deductions, credits, or taxable income, and negotiates payment plans and penalty abatements. We also work to resolve tax liens or levies and guide you through any other tax controversies. Whatever the nature of your tax problem, we strive to find an effective resolution.
The timeline for resolving a tax audit varies widely depending on the complexity of the issue, the amount of documentation needed, and the IRS or state agency's workload. Straightforward matters may be resolved in weeks or a few months once you provide the requested records and clarifications. More involved audits involving multiple tax years, unfiled returns, or disputed deductions can take six months to a year or longer. We work diligently to advance your case, keep you informed of timelines, and do everything possible to expedite a resolution.
Our tax audit defense team consists of Certified Public Accountants, enrolled agents, and tax attorneys with decades of experience representing individuals and businesses before the IRS and state tax authorities. Many of our professionals have worked as former IRS auditors or agents, giving us insight into how audits are conducted and how to negotiate effectively. We continuously update our knowledge of tax laws, regulations, and IRS procedures to provide knowledgeable representation and secure the best possible outcomes for our clients.
