Corviniti Accounting in New York City
Our headquarters at 575 5th Avenue. CPA-led accounting, tax, and CFO advisory for New York City businesses, from single-owner companies to public filers.
Where we are. 575 5th Avenue, 14th Floor, in Midtown Manhattan. This is our headquarters and the only office with a Google Business Profile today.
What we do here. The full practice: technical accounting and SEC reporting for companies going public or already there, CFO advisory, and the bookkeeping, accounting, and tax that small and mid-sized New York businesses depend on.
Why the city matters. New York City businesses file under two layers that most of the country does not have. The city taxes on top of the state, runs its own examinations, and the state runs residency audits among the most aggressive anywhere.
Corviniti Accounting is an accounting advisory firm headquartered at 575 5th Avenue, 14th Floor, New York, NY 10017. New York is where the practice started and where most of our team sits. The work runs from technical accounting and SEC reporting for companies approaching or already in the public markets, through CFO advisory, down to the monthly bookkeeping and tax filings a single-owner business needs. A CPA leads every engagement.
New York City is a genuinely harder place to file than most. The city levies its own business taxes on top of New York State's, including the Unincorporated Business Tax on sole proprietors and partnerships and an entity-level tax on S corporations the federal election does not protect you from. Sales tax in the five boroughs runs 8.875 percent. And New York State runs residency examinations that are among the most aggressive in the country, which reaches anyone who has moved, works a hybrid schedule, or keeps a place here. Those are the things this page goes into.
What we do from this office, the city and state rules behind it, and how to reach us is below.

The Detail
The gaps, and how we close each one
Topic 01
What we do from the New York office
Corviniti covers a wider range than most firms of our size, so it is worth being specific about what actually happens here.
How we handle it
Three bodies of work run out of this office. Technical accounting and reporting: revenue and lease positions under ASC 606 and ASC 842, equity and debt instruments, business combinations, the memos an auditor will actually accept, and SEC reporting for S-1, 10-K, and 10-Q filers. IPO and SPAC readiness: closing the gap between private-company books and what an effective registration statement requires, including the PCAOB audit uplift, cheap stock, the control environment, and the close process a public company has to run. Operating finance: fractional CFO work, outsourced accounting, and the bookkeeping and tax that small and mid-sized New York businesses need every month. The last of those is what most of our local pages cover, and it is a real practice: the same people who handle a public-company close set up a restaurant's chart of accounts.
Topic 02
The New York City tax layer
Owners who move a business into the city, or who incorporate here without local advice, are routinely surprised that the federal and state setup does not carry over. The city taxes separately, and it does not recognise some elections the federal government does.
How we handle it
The city taxes that reach an ordinary business: the Unincorporated Business Tax at 4 percent on the city income of sole proprietors, partnerships, and LLCs, with a return required once business gross income passes 95,000 dollars; an entity-level tax on S corporations, because New York City does not recognise the federal S election and taxes the company itself at 8.85 percent under the General Corporation Tax, which is the single most common surprise we see; the Commercial Rent Tax for tenants in Manhattan below 96th Street above the rent threshold; and the MCTMT payroll tax once quarterly payroll expense passes 312,500 dollars. On top of that, sales tax in the five boroughs is 8.875 percent, made of the state's 4 percent, the city's 4.5 percent, and the 0.375 percent MCTD surcharge. We keep the books so each of these filings has the detail it needs already sitting there, and we file them.
Topic 03
The New York State layer, and the PTET
Above the city sits the state, and the state is where the largest planning lever for a profitable pass-through actually lives.
How we handle it
New York's pass-through entity tax lets a partnership or S corporation pay New York tax at the entity level, deduct it federally, and pass a credit to each owner. For a profitable firm it is usually the biggest number on the table, and the election has a hard date, so it is a decision made in advance or not at all. New York City has its own parallel election on top. The honest framing is that neither is automatic: the benefit depends on each owner's own return under the current federal SALT cap, so we model it per owner before electing. Alongside that sit the ordinary state items, the CT-6 S election that New York does require even though New Jersey no longer does, Article 9-A corporate rates including the zero percent rate for qualified manufacturers, and the sales tax registration and vendor collection credit that a retailer forfeits by filing late.
Topic 04
Residency, remote work, and people who left
This is the most expensive New York issue we deal with, and it reaches people who no longer think of themselves as New Yorkers.
How we handle it
New York tests residency two ways. Domicile asks where your life actually centres, and the state examines it in detail: where the family is, where the valuables are, the size and use of the homes, the business ties, and the days. Statutory residency is simpler and catches more people: keep a permanent place of abode in New York and spend more than 183 days here, and you are taxed as a resident regardless of where you are domiciled. Separately, the convenience of the employer rule treats a workday at home outside New York as a New York workday unless the home office clears the state's bona fide employer office test, which few do. That reaches commuters from New Jersey and Connecticut and anyone working a hybrid week. These examinations turn on records, so the work is mostly done before the letter arrives. We keep the day counts and the documentation, and we represent clients through the examination itself.
Topic 05
The New York businesses we work with
The city's economy is not one thing, and the accounting problems differ sharply by sector.
How we handle it
Venture-backed and public companies. Technology, fintech, digital assets, and life sciences companies that need accrual books, defensible technical positions, and reporting that survives diligence or an SEC review. This is the practice the rest of the firm is built around.
Professional services firms. Law, consulting, design, and advisory firms, where unbilled work in progress, partner compensation, the city's Unincorporated Business Tax, and the PTET decision are the recurring items. Attorney trust and IOLTA funds stay strictly separated from operating cash.
Restaurants, bars, and retail. Merchant deposits net of processor fees, tips through payroll, prepared food at the full 8.875 percent, and a books-to-point-of-sale tie-out, which is exactly what a New York sales tax examiner reconstructs.
Medical, dental, and professional practices. Insurance deposits reconciled back to billed production, provider compensation splits, and the entity and retirement-plan structure that lowers tax on a high-income practice.
Real estate owners and developers. Per-property reporting, depreciation and cost segregation, passive activity and real estate professional positions, and 1031 exchanges.
Contractors and the trades. Job-level costing, work in progress, and the capital-improvement versus repair sales tax split that Form ST-124 settles.

If you are looking for a specific service in a specific place, these go into more depth than this page does.
575 5th Avenue, 14th Floor, New York, NY 10017, in Midtown Manhattan. The phone number is (347) 472-1115 and the map above shows the exact location. Meetings are by appointment; most first conversations happen by phone or video because it is faster.
Do you work with small businesses, or only larger companies?
Both, genuinely. The same practice that handles technical accounting for venture-backed and public companies runs monthly bookkeeping and tax for single-owner New York businesses, at a flat monthly price. The small business work is not a side line; it is a substantial part of what this office does.
My S corporation is fine federally. Does New York City still tax it?
Yes, and this is the most common surprise we see. New York City does not recognise the federal S election, so the company itself is taxed at 8.85 percent under the General Corporation Tax even though the income also flows through to your personal return. It is worth modelling before you assume your federal structure carries over.
I moved out of New York. Can the state still tax me?
Possibly, and it is worth taking seriously. New York tests both domicile, meaning where your life actually centres, and statutory residency, which taxes you as a resident if you keep a place of abode here and spend more than 183 days in the state. Residency examinations here are among the most aggressive in the country and turn almost entirely on records, so the documentation is worth building while the year is open.
Do you have to be in New York to work with this office?
No. Most of our work is remote and our clients run across all fifty states. The New York office matters because it is where the team sits and because we know these rules cold, not because you need to be nearby.
