What it is. A bookkeeper records what happened; an accountant explains what it means and plans what to do next. You get monthly financials, tax planning across the year, and advice on entity, pricing, and cash.
Who it is for. Rochester businesses past the startup stage that need more than clean books: a profit number they understand, a tax bill managed before year-end, and a CPA to call before decisions, not after.
Why a New York firm. The planning that saves money is state-specific: the New York S election, the PTET SALT-cap election, and entity choices that only pay off if they are set up correctly and on time.
Bookkeeping tells you what already happened. Accounting tells you what it means and what to do about it. Corviniti's small business accounting service for Rochester covers both: we keep the books current, then use them, monthly financials read and explained, tax planned across the year instead of discovered in April, and a CPA available when you are weighing a hire, a price change, or an equipment purchase.
Most of the money an accountant saves a Rochester business is New York-specific and time-sensitive. The New York S corporation election is a separate filing from the federal one and is easy to miss. The pass-through entity tax election has to be made by March 15 of the tax year with no extension, and since the 2025 federal tax law it is a per-owner calculation rather than an automatic win: the federal SALT deduction cap is now roughly 40,000 dollars through 2029 but phases back toward 10,000 dollars once an owner's income passes about 500,000 dollars, so the election matters most for exactly the owners the phase-down catches. These are planning decisions, not filing chores, and they only work if someone is watching the calendar and your numbers together.
Corviniti serves Rochester and Monroe County small businesses with a team led by a licensed CPA at a flat monthly price, working under the same New York rules you file under, without the cost of a full-time controller. What the service includes, and where it earns its keep, is below.

The Detail
The gaps, and how we close each one
Service 01
Beyond data entry: accounting and advisory
Plenty of Rochester businesses have a bookkeeper and still cannot answer basic questions: which jobs or products actually make money, whether they can afford to hire, what their tax bill will be. Clean books are the input, not the answer.
How we handle it
We keep the books to standard and then work from them. Every month you get financial statements plus a short written read: what moved, what it means, and what to watch. We build the chart of accounts so it answers the questions you actually ask, by location, product line, or job, and we review margins as well as totals. When a decision is coming, a hire, a lease, a price increase, you get a CPA's answer grounded in your own numbers rather than a gut call. The point of the books is to make better decisions, and that only happens when someone reads them with you.
What you get: Monthly statements with a written read of what changed and what to do.
Service 02
Entity structure and the New York S election
The wrong entity, or the right entity set up wrong, quietly costs Rochester owners money every year: self-employment tax paid that a reasonable structure would have saved, or an S corporation that New York never actually recognized.
How we handle it
We review whether your structure still fits, sole proprietor, partnership, LLC, or S corporation, as your profit grows, and model the self-employment and payroll tax difference so the choice comes down to a number you can see. The New York rule: a federal S corporation is not automatically a New York S corporation. New York requires a separate election on Form CT-6, and without it the state taxes the entity differently than you expect. If an S election makes sense, we handle both the federal and the New York filing, set a reasonable owner salary to support it, and keep the payroll and distribution split documented so it survives review.
What you get: An entity recommendation modeled in dollars, with the federal and New York S elections filed.
Service 03
The PTET election: New York's SALT-cap workaround
The federal cap on deducting state and local taxes changed in July 2025: it is roughly 40,000 dollars through 2029, phases back down toward 10,000 dollars for owners with income above about 500,000 dollars, and is scheduled to snap back to 10,000 dollars for everyone in 2030. New York's workaround, the pass-through entity tax, still works, but whether it pays now depends on the owner, and the election deadline is unforgiving.
How we handle it
The pass-through entity tax (PTET) lets an S corporation or partnership pay New York income tax at the entity level, where it stays federally deductible, and passes a credit to the owners. For owners the phase-down pushes back to the 10,000 dollar cap, or whose state and local taxes exceed the cap, it can still save thousands a year; for owners comfortably under both, the federal benefit through 2029 may be small, which is why we model it per owner before electing. The catch is timing: the annual election must be made by March 15 of the tax year, with no extension, and estimated payments follow their own quarterly calendar. We run the math, make the election where it pays, calculate and schedule the estimated payments, and file the annual PTET return, then reconcile the credit onto the owners' New York returns so the benefit actually lands.
What you get: A PTET election made on time, with the credit reconciled onto the owners' New York returns.
Not sure your entity or your New York elections are set up right? Talk to a CPA before year-end, when the levers still work.
Tax planning across the year, not a March surprise
When the first time anyone looks at the tax bill is at filing, the levers are already gone. Retirement contributions, equipment timing, entity elections, and estimated payments all have to be decided during the year they apply to.
How we handle it
We plan taxes on a rolling basis off your live numbers. That means a projected federal and New York liability updated through the year, estimated payments sized so you are not penalized and not overpaying, and decisions timed while they still count: Section 179 and bonus depreciation on equipment, retirement plan contributions that fit an owner's cash, and the PTET and S-election calls above. One New York wrinkle we manage: the state does not follow federal bonus depreciation, so bonus taken federally is added back on the New York return and depreciated separately, which changes the state math on equipment timing. For Rochester businesses that sell taxable goods or services, we keep sales tax planning in the same view, since the 8 percent collected in Monroe County is a liability to manage, not revenue. The goal is no surprises in April and no money left on the table in December.
What you get: A rolling federal and New York projection with estimates sized to avoid penalties.
Service 05
New York compliance that owners forget
New York has a handful of recurring obligations that are small individually but generate penalties and administrative dissolution when missed, and they rarely land on an owner's calendar.
How we handle it
We track the ones that catch Rochester owners: the biennial statement due to the Department of State every two years; the annual LLC filing fee (Form IT-204-LL) that scales with New York-source gross income; partnership and corporate franchise filings; and 1099-NEC filings for contractors, due January 31. We also oversee payroll compliance where you run payroll through a provider, making sure the employer taxes are booked and the filings reconcile, even though we do not sell payroll as a standalone service. For anyone hiring, the upstate minimum wage is its own planning number: 16 dollars an hour in Rochester for 2026, a dollar below downstate, and indexed to inflation from 2027. One more, because the mailers are relentless: as of mid-2026, most Rochester LLCs have no beneficial-ownership report to file, since FinCEN exempted domestic companies from the federal rule and New York's LLC Transparency Act was amended to cover only non-U.S.-formed LLCs, so treat the official-looking compliance letters demanding a fee with suspicion and ask us before paying anyone. None of these are large on their own; together they are the difference between a business in good standing and one scrambling to reinstate.
Service 06
Built for how Rochester businesses actually operate
A general accountant treats every business the same. The advice that matters is specific to what you do and to the Rochester market you do it in.
How we handle it
We work with the main business types in the region: medical, dental, and specialty practices around the University of Rochester and Rochester Regional systems; optics, photonics, and precision manufacturers carrying the area's imaging heritage, where job costing and inventory decide the margin; contractors and trades that need profit tracked by job; restaurants and cafes from Park Avenue to the Public Market, where merchant fees and tips have to be unwound to real revenue; and the professional-services firms and startups coming out of accelerators like NextCorps. The reports, the KPIs, and the planning are tuned to your model, so the advice is usable rather than generic.
FAQ
Frequently asked questions
What is the difference between a bookkeeper and an accountant?
A bookkeeper records and reconciles transactions; an accountant interprets the results, plans the tax, and advises on decisions. We do both, so the books feed the planning instead of sitting unused. Many Rochester businesses start with our bookkeeping service and move up to accounting as the decisions get bigger.
Should my Rochester business be an S corporation?
It depends on your profit and how much you pay yourself. Above a certain net income, an S election can cut self-employment tax, but it adds payroll and a reasonable-salary requirement. We model the actual savings for your numbers, and if it makes sense we handle both the federal election and New York's separate CT-6, which is the step most owners miss.
What is the PTET and is it worth it?
The pass-through entity tax lets your S corp or partnership pay New York tax at the entity level, where it stays federally deductible, and gives you a credit on your personal return. Whether it pays changed with the 2025 federal tax law: the SALT cap is roughly 40,000 dollars through 2029 but phases back toward 10,000 dollars above about 500,000 dollars of income, so the election is most valuable for high earners and for anyone whose state and local taxes exceed the cap. We model it per owner. The election is due March 15 of the tax year with no extension, so it has to be planned ahead.
Do you prepare the tax returns too, or just the accounting?
Both. The same team that keeps your books and plans your taxes files the business returns and the owners' personal returns, working from finished books. No handoff to an outside preparer, and no January scramble.
How much does a small business accountant cost in Rochester?
A flat monthly price based on your size, transaction volume, and how much advisory you want, not an hourly meter. Send us your details and we will quote a specific number, usually within one business day.
Do you work with contractors and the trades?
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.
