More Than Just Tax Preparation
A CPA Partner Who Invests in Your Success
Business owners choose DWK Tax & Accounting because they get direct access to a licensed CPA who understands their industry, their goals, and their numbers, not a revolving door of staff.
Licensed Illinois CPA
David Korzeniowski is a licensed Certified Public Accountant in the State of Illinois, not a seasonal tax preparer or a software dashboard. Every return is prepared and reviewed by a CPA who is accountable for accuracy and compliance.
Small Business Experience
8+ years working with contractors, restaurants, medical practices, law firms, e-commerce, real estate investors, and consultants across DuPage County. Industry-specific knowledge means better deductions and fewer surprises.
Year-Round Support
Tax strategy doesn't stop in April. David is available throughout the year for questions, planning conversations, and proactive adjustments, not just at filing season.
Proactive Tax Strategy
We plan ahead. Entity structure, timing, retirement contributions, and quarterly estimates are reviewed continuously so you keep more of what you earn, legally and strategically.
Personalized Planning
Every business is different. Recommendations are built around your specific circumstances, goals, and growth plans, never a generic template or a one-size-fits-all checklist.
Local & Accessible
Based in Wheaton, serving DuPage County and the western suburbs. You can call, email, or meet in person. No call centers, no overseas outsourcing, no account handoffs.
