About us
Your Success Is Our Business
Derjac Accounting & Tax was built on a simple belief: every individual and business deserves accurate, reliable, and professional financial guidance — without the runaround.
Our story
Built on Integrity. Driven by Results.
Derjac Accounting & Tax was founded with a clear mission: to provide North Charleston and the surrounding communities with the kind of professional financial services that were once only accessible to large corporations.
We believe that small business owners, entrepreneurs, and individuals deserve the same level of expertise, attention, and care as any Fortune 500 client. That belief shapes everything we do — from how we answer the phone to how we prepare your return.
Today, we serve hundreds of clients across South Carolina, offering a full suite of accounting, tax, consulting, and advisory services under one roof.
Our values
Accurate. Reliable. Professional.
Accuracy
Every number matters. We take precision seriously because errors cost you money, time, and peace of mind.
Reliability
We show up, we follow through, and we meet our deadlines. You can count on us — not just in April, but all year long.
Professionalism
From your first call to your final filing, we treat every client with respect, discretion, and the highest standard of service.
Integrity
We tell you the truth — even when it's not what you want to hear. Honest advice is the foundation of a lasting relationship.
