Business and personal tax, year-round planning, and representation before the IRS, New York State, and New York City, from a licensed CPA at a flat price.
What it is. Tax preparation, planning, and representation for Manhattan businesses and their owners, led by a New York-licensed CPA: business and personal returns, year-round planning, and standing before the IRS, New York State, and New York City.
What a CPA adds. A state license, professional accountability, and unlimited rights to represent you before the IRS. When there are real decisions or a real notice, that difference matters.
What we do not do. Audits, reviews, and compilations. Those reports require a NYSED-registered public accounting firm, which Corviniti is not, and we say so up front.
Corviniti provides bookkeeping, accounting, and tax services to small businesses across Manhattan, from the Financial District and Midtown to SoHo, the Flatiron and Chelsea, the Garment District, and Hudson Yards. Manhattan runs the densest small-business economy in the country, and it files under New York City's tax rules, which the rest of the state does not share.
A CPA is a state license that carries professional accountability and unlimited rights to represent a taxpayer before the IRS. In New York City that matters more than usual, because the city administers its own taxes and runs its own examinations, and the state's residency audits, which decide the city resident tax, are among the most aggressive in the country. Corviniti is an accounting and tax company led by a New York-licensed CPA.
Corviniti keeps books, plans tax, and files returns for Manhattan businesses under one roof, led by a CPA with Big Four experience. The full New York City tax detail behind this service is on our New York City CPA page; what it means for Manhattan is below.

The Detail
The gaps, and how we close each one
Service 01
The businesses Manhattan depends on
The books and tax work should fit the local economy. Here is what Manhattan's looks like and why it shapes the work.
How we handle it
Manhattan's small-business base is finance and the professional services around it: law, accounting, consulting, advertising, media and publishing, and the technology firms clustered in the Flatiron and Chelsea corridor once called Silicon Alley. The Garment District remains the historic center of the country's fashion and apparel design trade, SoHo and Fifth Avenue anchor retail, and Midtown and the Financial District hold the two largest central business districts in the city. Many of these are professional practices and partnerships, which means the New York City Unincorporated Business Tax and, for tenants below 96th Street paying 250,000 dollars or more a year in rent, the Commercial Rent Tax are live issues on the books. We keep the ledger in the shape those city filings need.
Service 02
Representation before the IRS, New York State, and New York City
A tax notice or audit letter is a deadline with consequences, and in New York City three agencies can send one: the IRS, the state, and the city.
How we handle it
As a licensed CPA, Ro represents taxpayers before the IRS, the New York State Department of Taxation and Finance, and the New York City Department of Finance. The most common matters are New York State sales tax audits, residency examinations on the city tax, and Unincorporated Business Tax questions before the Department of Finance, and the preparation for all of them starts with the clean, reconciled records we keep.
Anyone can hang a shingle at tax time. The question is who is licensed and accountable when the return has real decisions or the agency comes back.
How we handle it
A CPA holds a state license, is professionally accountable for the work, and has unlimited rights to represent you before the IRS. An unenrolled preparer can type a return but cannot fully stand between you and the agency. For a simple return the difference may not matter; with New York City tax exposure or a real notice, it does.
Service 04
Manhattan and New York City resources for owners
The registrations and filings Manhattan owners ask about most are spread across city and county offices, each with its own rules.
How we handle it
The offices a Manhattan owner actually uses: the New York County Clerk's Business Department at 60 Centre Street for assumed-name (DBA) certificates for sole proprietors and partnerships; the New York City Department of Finance for the Unincorporated Business Tax, the city corporation taxes, and the Commercial Rent Tax; NYC Small Business Services for licensing, financing help, and Business Solutions Centers; and the Manhattan Chamber of Commerce for the local business community. If a registration or filing is the thing blocking you, ask us; it is usually a quick answer.
FAQ
Frequently asked questions
Do you work with contractors and the trades?
Yes, as a licensed CPA. Past the return, that means representation if New York examines your sales tax, which for the trades usually depends on capital-improvement certificates (Form ST-124) and worker classification, employee versus 1099. We plan the entity and elections during the year and deal with the agency directly if a notice comes.
Do you work with medical and dental practices?
Yes, as a licensed CPA. We plan the entity, compensation, and retirement structure that lowers the tax on a high-income practice, sign the returns, and represent the practice if the IRS or New York questions owner compensation or the filing.
Do you work with restaurants and bars?
Yes, as a licensed CPA. Restaurants draw New York sales tax examinations more than most businesses, and the exam depends on tying point of sale records to the returns and the deposits. We keep the records that answer it, represent you if the state opens one, and claim the FICA tip credit on the return.
Do you work with e-commerce and retail sellers?
Yes, as a licensed CPA. The exposure for online sellers is multistate sales tax nexus and the marketplace facilitator rules, which generate most of the notices. We plan the nexus footprint, file the returns correctly, and represent you on state notices.
Do you work with law firms and professional services?
Yes, as a licensed CPA. That covers the trust-accounting discipline bar regulators expect, the PTET planning that is often a partner group's biggest lever, and representation before the IRS or New York if a return is questioned.
Do you work with real estate investors?
Yes, as a licensed CPA. We plan depreciation, cost segregation, passive-loss and real estate professional positions, and 1031 exchanges, and we defend those positions if the IRS examines them, since the aggressive ones draw scrutiny.
Do you work with businesses across all of Manhattan?
Yes, from the Financial District and Midtown to SoHo, the Flatiron, Chelsea, the Garment District, and Upper Manhattan. The work is done remotely on QuickBooks Online or Xero, so where in Manhattan you sit does not change the service. What matters is that your books are kept to New York City's tax rules, which is what we do.
Is Corviniti a CPA firm?
No. Corviniti is an accounting and tax company led by a New York-licensed CPA, not a public accounting firm registered with the New York State Education Department. Accordingly, we do not perform audits, reviews, or compilations of financial statements, the engagements a registered firm performs under professional standards (audits under the auditing standards, and reviews and compilations under the SSARS, the Statements on Standards for Accounting and Review Services). Tax preparation, planning, representation, and accounting do not require firm registration, and that is the work we do.
