At DuPage Tax Solutions, we focus on helping clients understand how the tax code applies to their financial decisions throughout the year. By combining proactive tax planning, business accounting services, and advisory, we help clients identify opportunities before they become missed opportunities.
Proactive, Not Reactive
We provide year-round tax planning and advisory services so you can make informed decisions before they affect your tax bill, helping you reduce taxes legally and avoid costly surprises.
Tax & Accounting Together
Your accounting records, tax return, and financial strategy work together—giving you a clearer picture of your business or personal finances. Accurate financial reporting supports better decisions and stronger long-term results.
Transparent & Collaborative
You’ll always understand what services you’re receiving, what they cost, and how they support your financial goals. We believe informed clients make better decisions, and we work with you throughout the year—not just during tax season.

Meet Our President
"I've always believed small business owners deserve more than someone who prepares a tax return after the year has ended. They deserve proactive guidance that helps them make better financial decisions throughout the year."
That belief became the foundation of DuPage Tax Solutions. Deyna founded the firm to help small business owners and individuals make informed financial decisions throughout the year, because the greatest tax-saving opportunities are identified and implemented before tax season—not when a return is being prepared.
Deyna earned her degree from Harvard University, where she received the Reginald H. Phelps Medal for exceptional academic achievement. She later served as a Research Associate at Harvard, strengthening the analytical approach she brings to every client relationship.
Today, she combines world-class education with practical experience to help clients understand the opportunities within the tax code and make informed financial decisions throughout the year. Whether helping a business owner develop a proactive tax strategy, improving financial clarity through Financial Trend Analysis, or assisting an individual with tax planning, her focus is always the same—building long-term relationships based on trust, transparency, and measurable results.

Phelps Medal for outstanding academic achievement. Her academic background equips her with a deep understanding of tax policy, financial systems, and strategic decision-making.
Before leading DuPage Tax Solutions, Deyna worked as a research associate at Harvard, contributing to projects involving tax incentives, business planning, and real-estate development. Today, she applies that analytical expertise to help business owners reduce tax exposure, improve profitability, and make informed financial decisions.
