A Premier Advisory Firm for Dual‑State Earners

Thousands of Fairfield County residents live in Connecticut but earn income in New York — creating one of the most confusing tax situations in the country. From residency rules to wage allocation to double‑tax exposure, multi‑state planning requires precision, documentation, and proactive strategy.

AP Accounting & Tax delivers the clarity and technical mastery high‑income dual‑state earners need.

Our Multi‑State Tax Planning Framework

CT vs. NY Residency & Domicile Analysis

We help you understand and document:

  • Primary residence

  • Domicile factors

  • Day‑count tracking

  • Commuter vs. remote‑work classification

  • NY “convenience of the employer” rules

  • This is essential for avoiding unnecessary NY taxation.

Wage Allocation for CT Residents Working in NYC

We ensure your income is allocated correctly between states:

  • W‑2 wage allocation

  • Remote vs. in‑office days

  • Employer location rules

  • NY convenience rule compliance

  • CT credit for taxes paid to NY

  • Incorrect allocation is one of the most common — and costly — mistakes.

Equity Compensation & Bonus Tax Planning

Executives with NYC‑based compensation face unique exposure. We structure:

  • RSU vesting events

  • Bonus timing

  • Multi‑year compensation planning

  • NY sourcing rules for equity income

  • This is a major tax‑savings opportunity when handled correctly.

Avoiding Double Taxation

We ensure you receive every credit and deduction available under CT law:

  • CT credit for NY taxes

  • Multi‑state credit optimization

  • Avoiding over‑withholding

  • Correcting employer withholding errors

  • Many high‑income earners overpay by thousands each year.

Remote Work & Hybrid Work Tax Strategy

The shift to hybrid work has created new tax exposure. We guide you through:

  • NY’s “convenience of the employer” test

  • CT residency protections

  • Remote‑work documentation

  • Employer policy alignment

  • This is one of the most misunderstood areas of CT/NY taxation.

Quarterly Multi‑State Tax Strategy Sessions

Your income, work location, and compensation structure evolve. Your tax strategy should evolve with it.

We meet quarterly to ensure:

  • Correct withholding

  • Accurate allocation

  • Proactive planning for bonuses, RSUs, and promotions

  • No year‑end surprises
