By appointment. A CPA replies within one business day.

Key takeaways
  • What it is. A CPA-led team keeps your books current every month: transactions categorized, every account reconciled, financial statements delivered on a fixed date, and New York State and New York City filings supported.
  • Who it is for. New York City businesses that have outgrown do-it-yourself QuickBooks or a part-time bookkeeper: trades, medical and dental practices, restaurants, professional services, e-commerce, and startups across the five boroughs.
  • Why a New York firm. Your books feed New York City filings that upstate and national bookkeepers do not touch: 8.875 percent sales tax, the Unincorporated Business Tax, the entity-level tax on S corporations, and the MCTMT. We keep the books to that standard.

Corviniti provides bookkeeping services to small businesses across New York City and all five boroughs. The service is monthly and flat-priced: we categorize your transactions, reconcile every bank and credit card account, deliver financial statements on a fixed date, and keep your books ready for tax filings instead of scrambling to rebuild them in March. The team is led by a CPA with Big Four experience.

New York City businesses file under two layers of tax, and the books have to reflect both. Sales tax in the five boroughs runs 8.875 percent, the state's 4 percent plus the city's 4.5 percent plus the 0.375 percent MCTD surcharge, and the city adds business taxes the state does not: the Unincorporated Business Tax on sole proprietors and partnerships and an entity-level tax on S corporations. We keep the collected sales tax separated from revenue, file the returns, and keep the books in the shape those city filings need.

Corviniti is a New York accounting advisory firm serving New York City small businesses. What the service covers, how it works month to month, and what it costs is below.

How it works

What a proper bookkeeping month looks like

Every month runs the same cadence: transactions categorized, every account reconciled, payroll booked, and financial statements delivered on a fixed date. This is the cycle we run for a New York City business.

Monthly bookkeeping cycle: categorize transactions, reconcile every bank and credit card account, book payroll, deliver financial statements on a fixed date, and send one batched question list.

New York City sales tax

New York City sales tax for a city seller

The combined rate in the five boroughs is 8.875 percent, the MCTD surcharge is part of it, and a handful of city rules change the math. The essentials on one page.

New York City sales tax for a city seller: Certificate of Authority 20 days before selling, 8.875 percent combined rate made of 4 percent state, 4.5 percent city, and 0.375 percent MCTD, quarterly returns due the 20th, the vendor collection credit, and the clothing and footwear exemption under 110 dollars.

How catch-up bookkeeping works

Most engagements start here. The path from months of unrecorded activity to a books-to-bank reconciliation you can file taxes from, show a lender, and rely on in an audit.

Catch-up bookkeeping path: gather bank and card records, rebuild the ledger, fix miscategorized history, reconcile every account, reach a books-to-bank reconciliation current through the last closed month, then keep it current monthly.

City business taxes

The city taxes your books have to support

New York City adds its own taxes on top of the state: the Unincorporated Business Tax on sole proprietors and partnerships, an entity-level tax on S corporations, and the MCTMT on payroll. Your books have to carry the detail each one needs.

New York City business taxes: the 4 percent Unincorporated Business Tax on sole proprietors, partnerships, and LLCs, the 8.85 percent city tax on C corporations and on S corporations at the entity level, the NYC pass-through entity tax, the Commercial Rent Tax in Manhattan below 96th Street, and the MCTMT payroll tax.

The Detail

The gaps, and how we close each one

Service 01

Monthly bookkeeping and reconciliations

Most small business books fail in the same two places: transactions categorized wrong, and accounts that never get reconciled. Both compound. By the time a loan application or a tax deadline forces the question, the profit number the owner has been watching all year is wrong.

How we handle it

We run your books on QuickBooks Online or Xero on a monthly cycle. Every transaction is categorized against a chart of accounts built for your business, every bank, credit card, and loan account is reconciled to the statement, and payroll entries from your payroll provider are booked correctly, including the employer taxes owners routinely miscount as profit. You get a profit and loss statement, balance sheet, and cash flow summary on the same date every month, with a short note on anything that moved. When something needs your answer, it comes as one batched question list, not a drip of emails.

What you get: Reconciled books and a three-statement financial package on a fixed date every month.

Service 02

Catch-up and cleanup bookkeeping

Many New York City businesses come to us behind: months or years of unrecorded activity, a QuickBooks file that no longer matches the bank, balances that have been wrong since an old bookkeeper left. The filing deadlines come due whether or not the books are ready.

How we handle it

Cleanup is usually where an engagement starts. We rebuild the ledger from bank and credit card records, fix miscategorized history, reconcile every account to the statements, and clear the junk balances that accumulate in accounts nobody reviews. The deliverable is a books-to-bank reconciliation your tax preparer, your lender, or an auditor can rely on, brought current through the most recent closed month, and then kept current monthly so the backlog never rebuilds. If prior-year returns were filed off bad books, we flag the differences so your tax preparer can decide what needs amending.

What you get: A books-to-bank reconciliation current through the last closed month, quoted as a one-time project.

Service 03

New York City sales tax at 8.875 percent

Sales tax is where New York City small businesses get hurt. The combined rate in the five boroughs is 8.875 percent, the filing calendar is the state's, and the money collected is the state's money sitting in your bank account. Businesses that treat it as revenue discover the problem at filing time, with penalties attached.

How we handle it

We set the books up so sales tax collected posts to a liability, not to income, and reconcile that liability to what the returns actually remit. New York City sellers register with the New York State Tax Department for a Certificate of Authority at least 20 days before making taxable sales, then file on the schedule the state assigns: quarterly returns due March 20, June 20, September 20, and December 20 for most businesses, monthly once taxable sales pass 300,000 dollars in a quarter. The 8.875 percent rate is made of the state's 4 percent, the city's 4.5 percent, and the 0.375 percent Metropolitan Commuter Transportation District surcharge, which applies everywhere in the five boroughs. Two city specifics worth knowing: clothing and footwear under 110 dollars per item are fully exempt, and filing on time pays a little through New York's vendor collection credit, which a late return forfeits. We prepare and file the returns, and keep the exemption and resale certificates that support any nontaxed sale.

What you get: Registered, reconciled, and filed New York City sales tax, with the certificates that support every nontaxed sale.

Service 04

The New York City business taxes your books feed

New York City taxes businesses on top of the state, and the city taxes catch owners who assume their federal or state setup carries over. It does not. The city runs its own rulebook, and the books have to carry the detail each city tax needs.

How we handle it

The city taxes that touch a small business: the Unincorporated Business Tax, 4 percent on the New York City income of sole proprietors, partnerships, and LLCs, with a filing required once business gross income passes 95,000 dollars; an entity-level tax on S corporations, because New York City does not recognize the federal S election and taxes the company itself at 8.85 percent; and the MCTMT payroll tax that five-borough employers owe once quarterly payroll expense passes 312,500 dollars. We keep the books so the income, payroll, and owner-draw detail each of these filings needs is already there, and we flag the ones that apply to your structure so nothing surfaces as a surprise at filing time.

What you get: Books that carry the income, payroll, and owner-draw detail the city's UBT, corporation, and payroll taxes need.

Service 05

Bookkeeping for New York City's main industries

New York City's economy is not generic, and a bookkeeper who treats every business the same misses what matters in each. The city's economy centers on finance and professional services, a dense layer of restaurants and retail, the trades that build and maintain it, healthcare, and a large creative and technology sector. Here is what is genuinely different about the books in the ones we see most.

How we handle it

Contractors and the trades. Profit lives at the job level, so we track costs by job, carry work in progress correctly, and manage the New York sales tax split the trades get audited on: capital improvements are exempt with a Form ST-124 certificate from the customer, repairs and maintenance are taxable, and the certificate file is what settles it.

Restaurants and cafes. The daily reality is merchant deposits net of processor fees, tips flowing through payroll, and prepared food taxable at the full 8.875 percent. We unwind deposits to gross sales so the books match the point of sale system, which is exactly the tie-out a New York sales tax auditor runs.

Professional services. Law, consulting, and design firms depend on unbilled work in progress and retainers, and as unincorporated businesses many owe the city's Unincorporated Business Tax, so we keep the books in the shape that filing needs. Attorney books add escrow and IOLTA funds that must stay strictly separated from operating cash.

Medical, dental, and therapy practices. Practice books have to reconcile insurance deposits, net of adjustments and clawbacks, back to the production the providers actually billed, and keep provider compensation splits clean enough to survive a partner meeting.

E-commerce and retail. New York's marketplace facilitator rules mean the marketplace collects on marketplace sales while you still file, direct-channel sales remain yours to collect, and out-of-state sales raise nexus questions. We keep the channels separated so the sales tax return is right by design.

Startups and technology companies. Venture-backed companies need accrual books, deferred revenue handled correctly, and investor-ready reporting from the first check, because cleanup during a diligence process is the most expensive kind. This is the same technical accounting the rest of our practice does for public and venture-backed companies.

What you get: A chart of accounts and monthly reports built for your business type, not a generic template.

Service 06

How we work with your business, month to month

A fair question before hiring any bookkeeper: what does the month actually look like from your side, and how do you reach us when something comes up?

How we handle it

The work is done in QuickBooks Online or Xero, read-only bank feeds, and a shared document inbox for the statements and bills we need. You get a fixed monthly delivery date, a standing way to reach us, video calls when a conversation beats an email, and a CPA who answers within one business day. You also get a team led by a New York-licensed CPA at a flat monthly price a solo bookkeeper cannot match on depth: the same practice handles technical accounting for venture-backed and public companies, and your books are kept to that standard.

What you get: A fixed delivery date, one batched question list, and a CPA who replies within one business day.

FAQ

Frequently asked questions

How much do bookkeeping services cost in New York City?

A flat monthly price set by your transaction volume, number of accounts, and whether you need cleanup first, not an hourly meter. Tell us about the business and we will send a specific number, usually within one business day. Solo local bookkeepers may quote less per month; a CPA-led team is priced against the cost of the errors it prevents.

Can you catch up books that are months or years behind?

Yes, and it is one of the most common ways engagements start. We rebuild from bank and credit card records, reconcile every account, and bring you current through the last closed month, then keep it current monthly. Cleanup is quoted as a one-time project alongside the monthly price.

Do you file New York City sales tax returns?

Yes. We prepare and file the quarterly or annual returns, reconcile the 8.875 percent collected in the five boroughs to the liability on the books, and keep the resale and exemption certificates that support nontaxed sales. If you are not yet registered for a Certificate of Authority, we handle that first.

Do your books handle the New York City Unincorporated Business Tax?

Yes. If you are a sole proprietor, partnership, or LLC doing business in the city, the 4 percent Unincorporated Business Tax may apply, and it is filed on the city's own forms. We keep the books so the New York City income and the owner-service detail that filing needs is already there, and coordinate it with the tax return.

Do you also prepare tax returns, or only the books?

Both. Corviniti prepares business returns (S corporations, partnerships, C corporations, Schedule C), the city business filings, and personal returns for owners, working directly from books we kept. One team, no handoff, and no January scramble to find a preparer who will accept someone else's ledger.

Do you do bookkeeping for contractors and the trades?

Yes, we work with contractors, electricians, plumbers, HVAC companies, and general construction regularly, including job costing, work in progress, and the New York capital-improvement sales tax rules the trades get audited on. We work with the field service and job management platforms these businesses use, including Jobber, ServiceTitan, Housecall Pro, and Buildertrend, and bring that activity into your QuickBooks Online books so job profit and payments reconcile every month.

Do you work with medical, dental, and therapy practices?

Yes, we work with dental offices, medical practices, and therapy and counseling groups regularly, including reconciling insurance deposits net of adjustments and clawbacks back to billed production and keeping provider compensation splits clean. We work with the practice management systems these offices use, including Dentrix, Eaglesoft, athenahealth, and Tebra, and bring that activity into your QuickBooks Online books so collections and payer deposits reconcile to what the providers actually billed.

Do you do bookkeeping for restaurants and cafes?

Yes, we work with restaurants, cafes, bars, and food trucks regularly, including merchant deposits net of processor fees, tips run through payroll, and prepared food taxed at the full rate. We work with the point of sale systems these businesses use, including Toast, Square, and Clover, and bring that activity into your QuickBooks Online books so daily sales tie back to the register and the sales tax return is right.

Do you do bookkeeping for e-commerce and retail businesses?

Yes, we work with online sellers, Shopify stores, and brick-and-mortar retailers regularly, including separating marketplace-collected sales tax from your direct sales and tracking nexus as you sell into other states. We work with the sales and payment platforms these businesses use, including Shopify, Amazon, Stripe, and Square, and bring that activity into your QuickBooks Online books so each channel's revenue, processor fees, and sales tax are recorded correctly.

Do you work with law firms and professional services?

Yes, we work with law firms, consultants, engineers, and agencies regularly, including unbilled work in progress, retainers, and the strict separation of attorney trust and IOLTA funds from operating cash. We work with the practice and billing platforms these firms use, including Clio, MyCase, and LawPay, and bring that activity into your QuickBooks Online books so trust balances, billings, and collections reconcile every month.

Do you do bookkeeping for real estate and property management?

Yes, we work with landlords, real estate investors, and property managers regularly, including a separate profit and loss per property, security deposits held apart from income, and depreciation schedules kept current. We work with the property management platforms these businesses use, including AppFolio, Buildium, and Yardi, and bring that activity into your QuickBooks Online books so each property's income, expenses, and owner draws stay clean.
