Business Tax Preparation in Rochester, NY
Federal and New York business returns filed from reconciled books, with the CT-6 S election and the PTET SALT-cap election handled, and no April surprises.
What it is. Preparation and filing of your federal and New York business returns, plus the owner's personal return, by a CPA working from reconciled books, with the New York-specific elections handled.
Where the value is. Not the data entry. It is the New York S election, the PTET SALT-cap election, entity-correct treatment, and estimated taxes managed so the return has no surprises.
Why a New York firm. New York business tax has its own forms and its own elections. A preparer who does not live in the New York rules leaves money and compliance on the table.
Corviniti prepares and files business tax returns for Rochester companies: S corporations (Form 1120-S), partnerships and multi-member LLCs (Form 1065), C corporations (Form 1120), and single-owner businesses on Schedule C, together with the matching New York returns and the owners' personal returns. Every return is prepared by a CPA from reconciled books, so filing is a quick assembly of books that are already done, with no year-end reconstruction billed at tax-season rates.
The value of good business tax preparation in New York is in the elections and treatment that a preparer working outside the New York rules misses: the separate New York S election, the pass-through entity tax election, modeled per owner now that the 2025 federal tax law raised the SALT cap to roughly 40,000 dollars with a phase-down for high earners, entity-correct handling of owner compensation and distributions, and estimated payments sized so you are neither penalized nor lending the government money interest-free. Get those right and the return is lower and cleaner; get them wrong and no amount of careful data entry recovers it.
For Rochester and Monroe County businesses, we keep books, plan taxes, and file returns under one roof. That means the return is prepared by the same people who know your numbers, and the planning that lowers it happens during the year, not at the filing table. What we file, and the deadlines that govern it, is below.

The Detail
The gaps, and how we close each one
Service 01
The right return for your entity, federal and New York
Each entity type files differently, and each federal return has a New York counterpart that does not always work the way owners assume. Mismatches between the books, the federal return, and the state return are where problems start.
How we handle it
We prepare the federal return for your structure, 1120-S for S corporations, 1065 for partnerships and multi-member LLCs, 1120 for C corporations, Schedule C for sole proprietors, and the matching New York return: CT-3-S for New York S corporations, IT-204 for partnerships, and CT-3 under the Article 9-A franchise tax for C corporations, at a 6.5 percent business-income rate for most small companies. New York's corporate tax also carries a fixed dollar minimum based on New York receipts, starting at 25 dollars, owed even in a low-profit year, and qualified New York manufacturers, a status many Rochester optics and machining companies can meet, pay a 0 percent business-income rate with reduced minimums, which is worth checking rather than assuming. Owner K-1s tie to the return, and the return ties to the books, so the three reconcile and an examiner has nothing to pull on.
What you get: The federal and New York returns for your entity, reconciled to the books.
Service 02
The New York S election (CT-6), and why federal is not enough
A business that elected S corporation status federally often assumes New York agrees. It does not, automatically, and the gap can mean the state taxing the company as a C corporation and a nasty correction later.
How we handle it
New York requires its own S election on Form CT-6, separate from the federal Form 2553. Until New York accepts it, the state generally does not treat you as an S corporation, whatever your federal status. We confirm your New York S status, file the CT-6 where it is missing, and make sure the election, the reasonable owner salary that supports it, and the distribution treatment all line up on the New York return. If a prior year was filed on the wrong assumption, we flag it so it can be corrected before the state does.
What you get: A filed CT-6 and a New York S status you can rely on.
Service 03
The PTET election, filed and reconciled
The pass-through entity tax remains one of the biggest levers for high-earning Rochester pass-through owners, and it is the one most commonly missed because it lives outside the normal return, follows a strict separate calendar, and, since the 2025 federal SALT cap changes, has to be justified owner by owner instead of assumed.
How we handle it
We confirm the PTET pays for your situation under the current federal SALT cap (roughly 40,000 dollars through 2029, phasing back toward 10,000 dollars above about 500,000 dollars of income, and scheduled to revert to 10,000 dollars in 2030), make the annual election by the March 15 deadline (which has no extension) through the entity's Business Online Services account, calculate and schedule the quarterly estimated payments due March 15, June 15, September 15, and December 15, file the annual PTET return, and reconcile the resulting credit onto each owner's New York personal return so the deduction actually converts into cash saved. Done piecemeal by separate bookkeepers and preparers, this is exactly where the benefit leaks; done by one team, it lands cleanly.
What you get: The PTET elected, paid, filed, and reconciled to each owner's return.
Unsure last year's business return was done right, or that New York recognizes your S corp? Talk to a CPA before you file again.
Estimated taxes and the deadlines that govern the year
Business tax depends on deadlines across the whole year. Miss the pass-through deadlines or underpay the estimates and you add penalties to a bill that was avoidable.
How we handle it
We manage the calendar: 1099-NEC to contractors by January 31; S corporation and partnership returns due March 15; C corporation and personal returns due April 15; six-month extensions filed where needed, with the reminder that an extension to file is not an extension to pay. Federal and New York estimated payments are sized off your live numbers and a safe-harbor calculation, so you avoid underpayment penalties without parking cash at the IRS. The result is a filing season with no scramble and no surprise balance due.
What you get: Estimated payments sized to a safe harbor on the full deadline calendar.
Service 05
Clean books in, a defensible return out
A return is only as good as the books under it. Filed off a ledger that does not reconcile, even a technically correct return sits on a foundation an auditor can dismantle.
How we handle it
Because we keep books to a books-to-bank reconciliation standard, the return is built on numbers that tie out: reconciled cash, clean owner accounts, documented fixed assets and depreciation, and contractor detail that supports the 1099s. If you come to us at filing time with books that are behind or wrong, cleanup comes first, quoted as a one-time project, because filing off bad books just moves the problem into an amended return later. The deliverable is a return your lender, the IRS, and New York State can all rely on.
Service 06
The owner's personal return, coordinated with the business
For most Rochester small businesses, the business and the owner's personal taxes are one connected problem. Filed by two different people, the K-1, the PTET credit, and the estimated payments fall through the gap between them.
How we handle it
We prepare the owner's personal return (Form 1040 and New York IT-201) alongside the business return, so the K-1 flows correctly, the PTET credit is claimed, the home-office and vehicle positions are consistent, and the personal estimated payments account for the business income. One team sees both sides, which is how the pieces that connect the two returns actually get connected. For owners whose personal situation is more involved, our personal tax accountant page covers the individual side in depth.
FAQ
Frequently asked questions
Do you file both the federal and New York business returns?
Yes. We prepare the federal return for your entity and the matching New York return (CT-3-S, IT-204, or CT-3), plus the owners' personal returns. Everything is filed from reconciled books by the same team, so the numbers tie out across all of it.
We elected S corp federally. Are we set for New York?
Not necessarily. New York requires a separate S election on Form CT-6. Without it, New York can tax you as a C corporation. We check your New York S status and file the CT-6 if it is missing, and flag any prior year that was filed on the wrong assumption.
Can you still help if our books are a mess at filing time?
Yes. We clean up and reconcile first, quoted as a one-time project, then file from books that tie out. Filing off bad books just creates an amended return later, so cleanup is the right first step.
When are the business tax deadlines?
1099-NEC to contractors by January 31; S corporation and partnership returns March 15; C corporation and personal returns April 15; six-month extensions available, though an extension to file is not an extension to pay. We manage the full calendar, including the separate PTET dates.
How much does business tax preparation cost?
It depends on your entity, complexity, and whether cleanup is needed first. We quote a flat, specific price up front rather than an hourly meter, usually within one business day of seeing your details.
Do you prepare returns for contractors and the trades?
Yes, the business return and the owner's. The items that decide a contractor's tax: the accounting method for long jobs (cash, accrual, or percentage-of-completion), work in progress on the return, the New York capital-improvement versus repair sales tax split, Section 179 and bonus depreciation on vehicles and equipment, and the S corporation and PTET elections for a profitable shop.
Do you prepare returns for medical and dental practices?
Yes, for the practice and its owners. The items that matter at practice income levels: entity choice (an S corporation is common), reasonable owner compensation, equipment depreciation, retirement-plan contributions that shelter high income, and the PTET election modeled per owner.
Do you prepare returns for restaurants and cafes?
Yes, for the business and its owners. The items that matter: the FICA tip credit on the employer payroll tax paid on reported tips, which is real money most preparers skip, Section 179 and bonus depreciation on equipment and build-out, cost of goods sold, and a return that reconciles to the sales tax you filed.
Do you prepare returns for e-commerce and retail sellers?
Yes, for the business and its owners. The items that matter: inventory and cost of goods sold accounting, sales tax nexus across states and the marketplace facilitator rules, fulfillment and home-office treatment, and the entity and PTET elections as the business scales.
Do you prepare returns for law firms and professional services?
Yes, for the firm and its owners. The items that matter: the cash versus accrual method, client trust funds kept out of income, partner and shareholder compensation, the PTET election that is often a partner group's largest lever, and the qualified business income deduction limits that apply to specified service businesses at higher incomes.
Do you prepare returns for real estate investors?
Yes, for investors, landlords, and property managers. The items that matter: depreciation and cost segregation to accelerate deductions, the passive activity loss rules and the real estate professional status that can unlock them, 1031 like-kind exchanges, and per-entity returns when properties sit in separate LLCs.
