What it is. A CPA-led accounting service for Staten Island owners: monthly financials you can act on, entity and New York City tax planning, the S and PTET elections handled, and a person to call before decisions.
Who it is for. Businesses across Staten Island past the startup stage that need more than clean books: a profit number they understand, a city tax bill managed before year-end, and a CPA to call before decisions.
Why local knowledge. New York City has taxes the rest of the country does not: the Unincorporated Business Tax, an entity-level tax on S corporations, and the city pass-through entity tax. They change the entity math for Staten Island owners, and a national accountant misses them.
Corviniti provides bookkeeping, accounting, and tax services to small businesses across Staten Island, from St. George and the Hylan Boulevard corridor to New Dorp, Forest Avenue, Bulls Head, and the West Shore. Staten Island has a small-business economy built on healthcare, retail, and the trades, and it files under New York City's tax rules.
A small business accountant interprets the numbers, plans the tax before the year closes, and advises the decisions that turn on the financials. In New York City the planning is worth more, because the city taxes stack on the state and federal layers: the Unincorporated Business Tax on unincorporated owners, an 8.85 percent entity-level tax on S corporations, and the state and city pass-through entity taxes that can convert some of that into a federal deduction.
Corviniti keeps books, plans tax, and files returns for Staten Island 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 small business accountant page; what it means for Staten Island is below.

The Detail
The gaps, and how we close each one
Service 01
The businesses Staten Island depends on
The books and tax work should fit the local economy. Here is what Staten Island's looks like and why it shapes the work.
How we handle it
Staten Island's small-business base leads with healthcare, its single largest employer, followed by retail along the Hylan Boulevard corridor and at the Staten Island Mall and Empire Outlets, a large layer of construction and contracting firms, professional-services practices, restaurants, and a maritime and industrial economy on the West Shore anchored by the Howland Hook Marine Terminal, now operating as Port Liberty New York. Many Staten Island businesses are family-run sole proprietors and partnerships in the trades and professional services, so the New York City Unincorporated Business Tax and job-level costing are live issues, and the borough's contractors get audited on the same New York capital-improvement sales tax rules the rest of the city does. We keep the books in the shape that trade and those city filings need.
Service 02
Entity choice, with the New York City twists
The entity decision that a national accountant models for federal tax alone gives the wrong answer in New York City, because the city taxes cut differently.
How we handle it
An S election can cut federal self-employment tax, but New York City taxes the S corporation itself at 8.85 percent because it does not recognize the election, so the city cost has to be in the model; and a sole proprietor or partnership owes the 4 percent Unincorporated Business Tax on city income, with a credit that phases out as profit grows. We model the entity across all three layers and handle the federal election and New York's separate CT-6.
The pass-through entity tax is one of the biggest levers for a profitable New York City pass-through, and the city adds a second one on top of the state.
How we handle it
We model whether the New York State PTET pays under the current federal SALT cap, roughly 40,000 dollars through 2029 with a phase-down for high earners, and whether the New York City PTET adds to it for a partnership with city-resident partners or an S corporation whose shareholders are all city residents. Both are elected online together by the March 15 deadline, which has no extension, and we reconcile the credits onto each owner's personal return so the deduction converts into cash saved.
Service 04
Monthly financials you can act on
The value of accounting is in financials that answer what made money, what did not, and what the next decision costs.
How we handle it
We deliver a monthly package built around your business: the three statements, the metrics that drive your model, and a read on what moved and why. When a decision is coming, a hire, a lease, a price change, we can show its effect before you commit, so the numbers inform the decisions rather than just record them.
Service 05
Staten Island and New York City resources for owners
The registrations and filings Staten Island owners ask about most are spread across city and county offices, each with its own rules.
Yes, and past the monthly books. We track costs by job and carry work in progress correctly so you know which jobs made money, manage the New York capital-improvement sales tax split that gets the trades audited, and plan the S corporation and PTET elections that fit a profitable shop. We work with the systems you run, including Jobber, ServiceTitan, and Buildertrend.
Do you work with medical, dental, and therapy practices?
Yes. We reconcile insurance collections net of adjustments back to billed production, keep provider compensation splits clean, and plan the entity, equipment, and retirement-plan choices that lower the tax on a high-income practice. We work with the practice systems you run, including Dentrix, Eaglesoft, and Tebra.
Do you work with restaurants and cafes?
Yes. We track prime cost, food and labor as a share of sales, run tips and tip credits correctly through payroll, keep sales tax on prepared food right, and watch the margins that decide whether a location works. We work with the point of sale systems you run, including Toast, Square, and Clover.
Do you work with e-commerce and retail businesses?
Yes. We separate marketplace-collected sales tax from your direct sales, track inventory and cost of goods sold so gross margin is real, and monitor economic nexus as you grow into new states. We work with the platforms you run, including Shopify, Amazon, Stripe, and Square.
Do you work with law firms and professional services?
Yes. We handle unbilled work in progress and retainers, keep attorney trust and IOLTA funds strictly separate from operating cash, and plan the S corporation and PTET elections that fit a partner group's income. We work with the platforms you run, including Clio, MyCase, and LawPay.
Do you work with real estate and property management?
Yes. We keep a profit and loss per property, hold security deposits separate from income, keep depreciation current, and plan the cost segregation, 1031 exchange, and entity moves that drive real estate returns. We work with the platforms you run, including AppFolio, Buildium, and Yardi.
Do you work with businesses across all of Staten Island?
Yes, from St. George and the Hylan Boulevard corridor to New Dorp, Forest Avenue, Bulls Head, and the West Shore, including the trades, healthcare practices, and retailers in the borough. 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.
