Get Started See What We DoGreenGrowth CPAs provides New York CPA services covering tax planning and compliance, accounting, outsourced CFO support, and business advisory for companies across New York City and the state. Engagements run remotely on shared systems, with a national team behind them.
New York businesses carry one of the most layered tax pictures in the country. State taxes stack with New York City's own business taxes, payroll-linked obligations, and multi-state apportionment questions the moment revenue crosses a border. Each layer lands on a different base, so the books have to separate them from day one.
GreenGrowth CPAs is an AICPA member firm, holds PCAOB registration under Firm ID 6580, and has served more than 1,500 clients since 2016. Call (800) 674-9050 or start online, and we will route you to the right practice lead.
What We Do
Tax, Accounting, and CFO for New York
Most New York clients come to us for one of three reasons: a tax position that spans more than one jurisdiction, books that need a real finance team, or a decision that needs advisory weight behind it. New York CPA services at GreenGrowth cover all three, each with a dedicated practice lead.
Tax Planning and Compliance
Federal, New York State, and New York City tax for businesses and their owners. The team models positions before year end, handles multi-state filings and apportionment, and covers Section 174A research expensing for companies building product.

Monthly close, reporting, forecasting, and CFO leadership without a full-time hire. Books built so your numbers hold up in diligence, a board meeting, or a lender review.
Explore outsourced CFOBusiness Advisory
Entity structure, transaction support, and the decisions between filings: raising, expanding into new states, or preparing the business for a sale. Advisory that connects the tax picture to the operating one.

New York Clients, National Team
How We Serve New York
Engagements run remotely on your systems, in your time zone, with scheduled calls and shared workpapers. New York clients get the same team, cadence, and turnaround as clients anywhere.
Who We Work With
Startups and growth companies in the city, established businesses statewide, licensed cannabis operators, and owners whose income crosses entities and states.
Beyond New York
The firm serves clients in all 50 states from eight offices, so a New York company expanding into New Jersey, Connecticut, or California keeps the same team as it grows.
Working with an out-of-state firm is normal now. Your regulators care about the filings, not the mailing address of whoever prepared them.

Serving Businesses Across New York
City and state obligations differ, and so does the tax picture between a Manhattan startup and an upstate operator. We work with businesses across all of it.
The Tax Picture
What a New York Business Navigates
Four layers of obligation land on four different bases. Businesses that track them in one line find out at filing time, which is the expensive way to find out.
| The layer | How it works | What we do |
|---|---|---|
| New York State taxes | State-level business and franchise taxes, filed on top of the federal return with their own bases and elections. | State positions modeled with the federal ones, so an election on one return does not create a surprise on the other. |
| New York City business taxes | The city levies its own business taxes on top of the state, including taxes that reach corporations and unincorporated businesses differently. | Entity structure and filings mapped to how the city actually taxes your form of business. |
| Payroll-linked obligations | Employer obligations tied to payroll and location, which shift when teams go remote or hybrid across state lines. | Payroll mapped to where people actually work, before an agency maps it for you. |
| Multi-state apportionment | Revenue from outside New York raises nexus and apportionment questions in every state it touches. | A nexus review, then filings in the states that need them and documentation for the ones that do not. |

Working with us from New York
How does GreenGrowth CPAs serve New York businesses?
Engagements run remotely on shared systems, with scheduled calls in your time zone and a national team of specialists behind them. New York clients get the same cadence and turnaround as clients in any state.
Do I need to meet my CPA in person?
No. Tax, accounting, and CFO work runs on your systems and shared workpapers, and most clients never need a physical meeting. Video working sessions replace the conference room.

Tax planning and compliance, full-service accounting, outsourced CFO support, and business advisory for New York companies and their owners, including licensed cannabis operators.
New York tax questions
Does New York City tax businesses separately from the state?
Yes. New York City levies its own business taxes on top of New York State taxes, and the city's rules reach corporations and unincorporated businesses differently. The entity form you choose changes which city obligations apply.
My company sells outside New York. Do I owe tax in other states?
Possibly. Revenue into other states raises nexus questions, and each state sets its own threshold for when filings are required. A nexus review answers it state by state, and documents the states where you do not owe filings as clearly as the ones where you do.
Does GreenGrowth CPAs work with New York cannabis businesses?
Yes. The cannabis practice has specialized in the industry since 2016 and covers New York's licensed market, including state cannabis taxes and IRC 280E strategy. The New York cannabis accounting page covers the market in detail.
