Our #Success Stories
Plan to Success
Mr. Brandon Evans, initially lacking a clear business plan and understanding of U.S. business laws, successfully established his LLC in Delaware with the help of professional consultants.

E-commerce Startup
In 2019, Mr. Jackson, who owns many companies, started an online store but didn’t know much about taxing online sales. This led to mistakes in his financial records, missing important information on funds and incomplete records of income and expenses, which is super messy.

Stuck in a special situation
Dustin and Rosie, a couple in their middle years, sold all their properties and assets for a stock market venture. Their gamble paid off with big profits, but it brought a huge tax bill of over 2 million USD, a financial challenge they didn’t even plan for.

Empowered Business in the U.S.
Joyce Ho, a entrepreneur from Vietnam, sought assistance from XOA TAX to navigate the complexities of establishing a business in the U.S. We provided comprehensive help so that Joyce Ho’s foreign-owned business not only launched successfully but also achieved profitability early on.
