Your Trusted Tax Experts in Texas



At Diego Tax Pros, we make tax filing simple, accurate, and stress-free. Our tax services are led by Daniel Siller, manager of the tax department, located in Del Rio and proudly serving clients across Texas. Daniel holds a degree in Accounting from St. Mary’s University, bringing professional expertise and attention to detail to every return.

We began offering income tax services because our insurance clients—many enrolled through the ACA Marketplace—needed help filing their taxes to stay compliant with the ACA’s reporting requirements. Listening to our community’s needs, we expanded our expertise beyond health insurance to ensure our clients had a reliable, trustworthy partner for their yearly tax filing.
