Welcome to Blandin Accounting & Tax Services LLC  

Based in Long Island | NY - Bilingual – English & Spanish


Hi, I’m Tatiana Blandin, but you can call me Tati 💌 

I’m a bilingual accountant, Certifying Acceptance Agent (CAA), and Annual Filing Season Program (AFSP) participant with over 8 years of experience helping individuals and small business owners gain clarity, confidence, and freedom in their finances.

 

When I handle your numbers, I see more than figures — I see your courage, your dreams, and the discipline it takes to build a better future. My goal is to help you stay compliant, lower your tax liability, and bring calm to what often feels like chaos.

 

✨ Rooted in Connection. Driven by Discipline. Always choosing Freedom.

Collaborative Services

While I personally focus on accounting, bookkeeping, and individual tax preparation,I collaborate closely with my colleague Mynor DeLeon of MDe Tax, who handles:

  • Payroll processing & tax filings (Forms 941, 940, NYS-45, etc.)
  • Sales tax filings (ST-100, ST-101)
  • Corporate & partnership tax returns (Forms 1120, 1120-S, 1065)
