About Theresa Thi
Theresa Thi Nguyen is an attorney who built a practice around tax and business law. She brings an academic background in taxation to the work she does for clients. Her day-to-day blends technical tax rules with practical business problems.
She earned a J.D. from Nova Southeastern University, where her studies included tax law and business law. After law school she pursued further specialization, completing an advanced law degree in taxation at the University of Washington School of Law. Those credentials shaped an early interest in the intersection of tax law and commercial practice.
Nguyen began practicing in areas where tax questions often drive business decisions. Over time she moved into private practice and into firm leadership. In 2015 she took on the role of managing member at the Law Office of Theresa Nguyen, PLLC, a small firm that handles tax matters for a mix of individual and corporate clients. Her practice grew from routine tax planning and compliance work to more complex advisory engagements.
Her work covers a range of tax-related issues. She assists clients with income and business tax planning, reporting requirements, and resolving disputes with tax authorities. The practice also addresses transactional elements of business law where tax consequences are central, such as entity selection and business structure. She handles both counseling and hands-on preparation of tax filings when cases require it.
Colleagues and clients describe her approach as pragmatic. She breaks down complex tax rules into actionable steps. That style matters in tax work, where a technical rule can have outsize business consequences. Nguyen balances technical analysis with attention to client priorities, whether the matter is a routine filing or a more involved restructuring.
Outside client work she has maintained ties to continuing legal education in taxation. She keeps current on developments in tax policy and practice that affect small businesses and individual taxpayers. That ongoing study informs the advice she gives and the strategies she pursues in practice.
Licensed to practice in Washington, Nguyen leads the Law Office of Theresa Nguyen, PLLC. Her practice concentrates on tax law and related business matters at the firm.
