Reliable, Insightful Tax Prep for Businesses and Entrepreneurs in San Jose

Expert Tax Preparation with Strategy Built In

Our mission is to provide our clients with the best solutions and we provide consultation unique to your situation. Since we are a relationship-based firm, we are available throughout the year for tax planning and advising.

Tax season doesn’t have to be stressful—or impersonal. At First Tax Service, we provide accurate, timely tax preparation services for business owners, content creators, and high-growth brands who want more than just a once-a-year filing. Our goal isn’t just to keep you compliant—it’s to help you understand the numbers behind your business and uncover opportunities for savings and smarter planning.

Led by trusted advisor Anh Nguyen, we offer a boutique experience grounded in deep tax knowledge, strong client relationships, and a proactive mindset. Whether you’re filing as an S Corp, a partnership, or a multi-entity structure, you can trust that your return will be handled with precision and care.

Business Tax Prep That Goes Beyond the Basics

We specialize in tax preparation for:

  • LLCs, S Corps, C Corps, and partnerships

  • Creative entrepreneurs with 1099 income or multiple revenue streams

  • Shopify sellers and online brands with product sales and sales tax considerations

  • Manufacturers and service-based businesses with complex cost structures

  • Founders with investment income, pass-through entities, or multi-state operations

From gathering documents to e-filing your returns, our process is thorough, collaborative, and tailored to your business model. We don’t believe in shortcuts—and we don’t outsource your financial future to generic platforms.

Clean Books = Stronger Returns

Tax prep doesn’t start in March—it starts with your numbers being clean all year. That’s why our tax preparation services often pair with bookkeeping, payroll, accounts payable, and fractional CFO support. When your financial data is up to date and organized, we’re able to complete your return faster, flag deductions you might otherwise miss, and help you prepare for what’s ahead.

We also review prior-year filings to catch errors or overlooked opportunities and offer recommendations for tax planning going forward—so your next tax season is even smoother.

Clarity. Accuracy. Confidence.

We don’t just file and forget—we explain, strategize, and advise. Our clients appreciate that they can ask questions, get context, and walk away from tax season feeling informed and empowered.
