Personal Tax Accountant in Brooklyn
Federal, New York State, and New York City personal returns prepared by a CPA, with the city income tax, residency, and equity income handled, and planning across the year.
What it is. Preparation and planning of your federal (1040), New York State (IT-201), and New York City personal taxes by a CPA, tuned to the city specifics: the city income tax, residency, co-op and condo relief, and equity income.
Who it is for. Individuals and families in Brooklyn with more than a W-2: business owners, investors, people with equity compensation, multiple-state income, or property, where the return has real decisions in it.
Why local knowledge. New York City taxes residents on top of the state, tests residency aggressively, and offers relief a national chain never claims. Getting the city side right for Brooklyn filers is where the money and the risk are.
Corviniti provides bookkeeping, accounting, and tax services to small businesses across Brooklyn, from Downtown Brooklyn and DUMBO to Williamsburg, Sunset Park, Bushwick, and Gowanus. Brooklyn is the most populous borough and one of the fastest-growing small-business economies in the city, and it files under New York City's tax rules.
The value in New York City is the city layer a national chain skips. Unlike most of the country, a New York City resident pays a separate city income tax on top of the state's, roughly 3.078 to 3.876 percent, so the combined marginal rate runs well above the state rate alone. The city also tests residency harder than almost any jurisdiction and offers relief most filers never claim, from the co-op and condo abatement to STAR.
Corviniti keeps books, plans tax, and files returns for Brooklyn 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 personal tax page; what it means for Brooklyn is below.

The Detail
The gaps, and how we close each one
Service 01
The businesses Brooklyn depends on
The books and tax work should fit the local economy. Here is what Brooklyn's looks like and why it shapes the work.
How we handle it
Brooklyn's small-business base is broad: food and beverage manufacturing and artisanal production, the creative industries of design, film, media, and art, a growing layer of technology and hardware startups, apparel and consumer-goods makers, and the construction and real estate that come with the borough's growth. The Brooklyn Navy Yard, a 300-acre industrial park with hundreds of businesses, and Industry City and the Brooklyn Army Terminal in Sunset Park anchor the borough's maker and manufacturing economy, while Downtown Brooklyn is the city's third-largest central business district. Many of these are unincorporated businesses that owe the New York City Unincorporated Business Tax, and their books have to carry the inventory, job, and channel detail their trade needs. We keep them in that shape.
Service 02
The New York City resident income tax
New York City is one of the few places where living inside the city line adds a separate personal income tax, and it is not avoidable by structure the way some taxes are.
How we handle it
A New York City resident pays a city income tax of roughly 3.078 to 3.876 percent on top of the state's 3.9 to 10.9 percent, reported on the state IT-201 return. We make sure it is calculated correctly, that any city credits you qualify for are claimed, and, for anyone who moved during the year, that the city tax is allocated to the right period rather than the whole year.
Because the city tax turns entirely on residency, the city and state test it aggressively, and a wrong answer either overpays the tax or invites a residency audit.
How we handle it
We handle the returns where where you live is itself the tax question: part-year moves and income allocation, residents earning in another state (with the resident credit), and anyone claiming a change of domicile away from the city, where the statutory-residence and 183-day tests decide the bill. We keep the documentation that answers a residency inquiry before it becomes an audit.
Service 04
Co-op, condo, and STAR property tax relief
New York City homeowners, especially co-op and condo owners, leave real money on the table because the relief is claimed in the wrong form or not at all.
How we handle it
The co-op and condo property tax abatement cuts the tax on a primary-residence unit by 17.5 to 28.1 percent depending on the building, and it is routinely missed. We confirm it along with STAR, capture the 529 college-savings deduction, and coordinate the property-tax picture with the rest of the return.
Service 05
Brooklyn and New York City resources for owners
The registrations and filings Brooklyn owners ask about most are spread across city and county offices, each with its own rules.
How we handle it
The offices a Brooklyn owner actually uses: the Kings County Clerk at 360 Adams Street for assumed-name (DBA) certificates for sole proprietors and partnerships; the New York City Department of Finance for the Unincorporated Business Tax and the city corporation taxes; NYC Small Business Services for licensing and financing help; the Brooklyn Chamber of Commerce, the largest chamber in New York State; and industrial development groups like Evergreen Exchange in North Brooklyn. If a registration or filing is blocking you, ask us; it is usually a quick answer.
FAQ
Frequently asked questions
Do you work with physicians, dentists, and other high-income professionals?
Yes. At your income the moves that matter are the PTET credit if you own the practice, backdoor and mega-backdoor Roth contributions, the net investment income tax and additional Medicare tax thresholds, and managing the practice K-1 alongside the personal return. We plan these while the year is still open.
Do you handle equity compensation, RSUs, ISOs, and stock options?
Yes, and the tax depends on timing. Exercising ISOs can trigger the alternative minimum tax, vested RSUs are usually under-withheld and leave a balance due, and the holding periods decide capital gains versus ordinary rates. We model the exercise and sale timing so the tax is planned ahead of the year-end.
Do you work with real estate investors and landlords on their personal return?
Yes. That means rental income and depreciation, the passive activity loss rules and when the real estate professional status unlocks them, cost segregation, and 1031 exchanges, handled on the personal return where most investors hold property.
Do you handle business owners' personal returns?
Yes, and we prepare the business return alongside it when you have one. The K-1 or Schedule C, the PTET credit, the qualified business income deduction, and the estimated payments connect the two returns, and we keep them lined up so nothing falls through the gap.
Do you work with self-employed tradespeople and independent contractors?
Yes. The items that matter: Schedule C income and the self-employment tax, vehicle, tool, and home-office deductions done correctly, quarterly estimated payments, and whether an S election would lower the self-employment tax as your profit grows.
Do you work with investors and retirees?
Yes. That means capital gains and loss harvesting, dividend and interest income across accounts, required minimum distributions and Roth conversion timing, and New York's favorable treatment of Social Security and pension income. We plan the income timing across the year.
Do you work with businesses across all of Brooklyn?
Yes, from Downtown Brooklyn, DUMBO, and Williamsburg to Sunset Park, Bushwick, and Gowanus, including the makers and manufacturers at the Brooklyn Navy Yard and Industry City. The work is done remotely on QuickBooks Online or Xero, so the neighborhood does not change the service. What matters is that your books are kept to New York City's tax rules.
