Proactive Tax Guidance

DuPage Tax Solutions did my company taxes and personal taxes last year. Fortunately, Deyna took the time to answer all my questions (and I had a lot of questions as many things had happen during the year that impacted my tax situation). She took the time to understand my situation and identified opportunities I otherwise would have missed.

Reliable Accounting Support

I had the pleasure of dealing with Deyna Parvanova this year instead of my regular accountant. Markedly, I didn’t realize that I had additional options in dealing with my tax situation until I talked to her. Needless to say that she earned herself my thanks and repeat business. Highly recommend her!

Responsive & Reliable Service

Deyna and her company handled my business accounting and did an exceptional job. Particularly, they were responsive and kept my books and tax filings clean, complete and organized.

Strategic Business Insight

It has been a pleasure working with DuPage Tax Solutions. Specifically, I started a Real Estate firm and wanted to ensure that the accounting was properly maintained. The team of experts has been awesome at holding my hand through the financial management process and helping me make firm business decisions from the beginning. Moreover, I know for sure that when I provide financials for my business, they are accurate and thorough.

Strategic Business Insight

Deyna at DuPage Tax Solutions brought several ideas to us that we hadn't looked at before. Thus, we're going to end up with significant savings from something we would have totally passed on if she hadn't brought this to our attention.
