A Choy CPA PLLC
I am a solo tax practitioner and NYC-based CPA with 25+ years of experience in Federal and State Business Income Tax Planning and Compliance for Corporations (C, S), Partnerships, LLCs for various industries (including tech, PE, retail, real estate). Prior to going solo in 2025, I was a Senior Federal Tax Manager for IBM corporate headquarters in Armonk, as well as for Bloomberg LP's income tax department. My specialties include Research Tax Credits, R&D related tax planning (Sec. 174A) and Other Incentives (e.g., Sec 199A Qualified Business Income Deductions). I handle IRS audit readiness and representation for corporations and partnerships in various income tax areas. I have extensive experience working with in-house tax counsel, tax litigation attorneys as well as IRS agents, territory manager and counsel on defending income tax deductions, foreign tax credits and research credits. I provide Pillar Two consulting for complex business entity structures, and provide guidance on implementation. I also provide Chinese and Hong Kong Tax consulting services for US companies with operations in the Greater China Region. I work part-time only and I am looking forward to connecting with other solo CPAs, CPAs who work for in-house tax departments and CPA firms.
