About Don Partners
Don Partners is a modern, revamped tax strategy and advisory family office based in Dallas. Powered by advanced AI tools and more efficient processes, our team of CPAs, Certified Financial Advisors, and tax law professionals delivers nationwide expertise with precision and speed. We are proud members of the Texas Society of CPAs and Enrolled Agents. Brandon Castro (Don) is a licensed Enrolled Agent authorized to practice before the IRS and has been successfully filing and resolving taxes since 2016. He earned his B.A. and completed the Executive Professional Accountant Program at the University of Texas at Dallas. He also fulfilled the educational requirements and hours toward CPA licensure, but instead chose to focus on specialized tax strategy and IRS representation. This path allows him to deliver the strongest possible combination of tax strategic advisory and wealth management services creating highly tailored strategic tax assessments, entity structuring plans, and proactive strategies so clients never pay more tax than legally required by the IRS Code while fully capturing every available government and IRS incentive.

About Us
A team focused on building clear, useful financial experiences
Our Mission
We specialize in bridging the common gaps between day-to-day accounting, forward-looking tax planning, and tax resolution. With more than a decade of hands-on experience resolving complex tax issues as a licensed Enrolled Agent, Brandon Castro (Don) brings deep expertise in IRS rules, audit processes, and strategic planning. Clients benefit from practical, real-world guidance on how the IRS actually audits, along with clear answers to even the most intricate tax questions.
We take a long-term, strategic approach while remaining highly responsive. Our team is always ready to answer questions or develop tailored tax strategies on short notice. By combining thorough technical knowledge with practical, real-world insight, we help clients prevent problems before they become liabilities. While we take great satisfaction in helping clients resolve and reduce existing IRS debt—often saving tens of thousands of dollars—we find equal fulfillment in preventing unnecessary tax burdens in the first place and maximizing every legal advantage to minimize overall tax liability.
What drives us

Success is built on accuracy and attention to detail. At Don Partners Firm, we meticulously review every number and transaction, ensuring your financials are accurate, compliant, and positioned to support informed decision-making.
Collaboration
We work as a trusted extension of your team. Our accountants and tax professionals partner closely with you to align every financial strategy, tax plan, and reporting process with your unique business goals and vision for growth.
Innovation
We combine deep current knowledge of tax laws and accounting standards with forward-thinking strategies. This allows us to identify opportunities, optimize your tax position, improve cash flow, and help you plan confidently for the future.
Do I have to live in Dallas to work with you?
Not at all. We love working with our local Dallas clients, but we also proudly serve business owners nationwide. Secure portals and video calls allow us to provide the same excellent service whether you’re just down the street or across the country.
What’s the difference between “Tax Prep” and “Tax Strategy”?
Think of Tax Prep as “reporting history”—we take what happened last year and put it on the right forms. Tax Strategy is “writing history”—we look ahead to structure your business, investments, and expenses in a way that legally minimizes what you owe. Strategy is where the real savings happen.
Cost of a consultation
It depends on what you need. A quick chat with our staff about filing your returns is generally free. A deep-dive Tax Strategy Session with TJ is a paid service because you’re getting a custom-built plan that often saves clients thousands of dollars. We’ll always be upfront about costs before you book.
What if I get audited?
We stand by our work. If you receive a notice from the IRS or state, we’ll help you understand it and respond. We don’t just file your taxes and disappear; we’re here to support you year-round.
