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 Jersey and Jersey City filings supported.
  • Who it is for. Jersey City businesses that have outgrown do-it-yourself QuickBooks or a part-time bookkeeper: trades, restaurants, medical and dental practices, professional services, e-commerce, real estate, and the financial-services consultancies along the waterfront.
  • Why a New Jersey firm. Your books feed New Jersey filings a New York or national bookkeeper does not touch: 6.625 percent sales tax, the Urban Enterprise Zone half rate, the Jersey City employer payroll tax, and a minimum state tax an S corporation owes even at a loss.

Corviniti provides bookkeeping services to small businesses across Jersey City and Hudson County. 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 licensed in New Jersey and New York.

Jersey City businesses file under rules that differ from New York's in almost every particular, and the books have to reflect the state they are actually in. New Jersey sales tax is 6.625 percent statewide with no county or municipal add-on, but a certified retailer inside an Urban Enterprise Zone charges half that on most in-person retail sales, and Jersey City is one of the state's 37 participating municipalities, designated when the program began in 1984. On top of the state layer, the city itself charges employers 1 percent of quarterly payroll for employees who do not live in Jersey City. We keep the collected sales tax separated from revenue, file the returns, and keep the payroll detail those city filings need.

Corviniti is an accounting advisory firm serving Jersey 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 Jersey City business.

Monthly bookkeeping cycle for a New Jersey business: categorize transactions, reconcile every bank and credit card account, book payroll and confirm any municipal payroll tax base, then deliver financial statements on a fixed date with one batched question list.

New Jersey sales tax

New Jersey sales tax for a Jersey City seller

One statewide rate of 6.625 percent, no county add-on, and a half-rate Urban Enterprise Zone in designated blocks of designated towns. The essentials, including which return each seller files.

New Jersey sales tax: 6.625 percent statewide with no county or municipal add-on, the 3.3125 percent Urban Enterprise Zone half rate for a certified retailer inside a designated zone, registration on Form NJ-REG at least 15 business days ahead, and the ST-50 quarterly, ST-51 monthly, and monthly UZ-50 zone returns.

Jersey City payroll tax

The Jersey City employer payroll tax

Jersey City charges employers 1 percent of quarterly payroll, but only on employees who do not live in the city. It cannot be withheld from wages, so the books have to carry residency and work location per employee.

The Jersey City employer payroll tax: 1 percent of quarterly gross payroll under Ordinance 18-133, owed only on payroll for employees who are not Jersey City residents, exempt below 2,500 dollars of quarterly payroll, filed quarterly, and never withheld from employee wages.

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 through the last closed month, then keep it current with a monthly close so the backlog never rebuilds.

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. For a Jersey City employer that includes the city payroll tax, which is an employer cost and not a payroll deduction, so it belongs in expenses rather than netted against wages. 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 Jersey 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. Two New Jersey items surface often in cleanup: sales tax collected that was booked to income instead of a liability, and quarters where the Jersey City payroll tax return was never filed at all. 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 Jersey sales tax at 6.625 percent

Sales tax is where small businesses get hurt, and New Jersey's version has a wrinkle New York does not. The statewide rate is 6.625 percent with no county or municipal add-on, which is simpler, but the Urban Enterprise Zone half rate is a certification you either have or do not, and businesses get it wrong in both directions.

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. Jersey City sellers register with the New Jersey Division of Revenue on Form NJ-REG at least 15 business days before the first taxable sale, then file the ST-50 quarterly return by the 20th after each quarter, with monthly ST-51 payments once the prior year's tax passed 30,000 dollars and the month's tax is over 500 dollars. The Urban Enterprise Zone rate of 3.3125 percent applies only when two things are both true: the business sits inside the mapped zone, which covers specific blocks rather than the whole city, and the retailer is certified. A certified zone business files the monthly UZ-50 in place of the ST-50 and ST-51, reporting all of its sales at both rates, and prepared food and most services stay at the full rate even inside the zone. Two related items round out the picture: a certified zone business can also buy up to 100,000 dollars a year of qualifying business purchases tax-free on the UZ-5 certificate, and purchases that arrive from out-of-state vendors untaxed owe New Jersey use tax, reported on the same returns. We prepare and file the returns, keep the half-rate and full-rate channels separated in the books, and hold the resale and exemption certificates that support any nontaxed sale.

What you get: Registered, reconciled, and filed New Jersey sales tax, with half-rate zone sales separated and every certificate on file.

Service 04

The Jersey City employer payroll tax

This is the local tax that catches businesses moving into Jersey City, because nothing in a federal or state payroll setup mentions it. Jersey City charges the employer, and only for the employees who do not live in the city, which means the calculation depends on data most payroll files do not track carefully.

How we handle it

Under Ordinance 18-133, the tax is 1 percent of quarterly gross payroll, and wages paid to Jersey City residents are excluded from the base. An employer whose gross quarterly payroll is under 2,500 dollars owes nothing. Returns and payments are quarterly, the revenue funds the city's public schools, and the employer may not deduct or withhold the tax from employee wages, so it is a true employer cost. Two details decide the number: the base captures services performed in Jersey City and also services performed elsewhere when they are supervised from Jersey City, and the residency split has to be tracked per employee rather than estimated. The returns are due the last day of the month after each quarter, and enforcement is tightening: a state law signed in January 2026 requires the state to share employer payroll data with Jersey City, so employers who never registered are now visible to the city. We keep the payroll records so each employee's residency and work location support the return, book the tax as an employer expense, and reconcile the quarterly filings to the payroll in the books.

What you get: A quarterly Jersey City payroll tax return built from per-employee residency and work-location records.

Service 05

Bookkeeping for Jersey City's main industries

Jersey City's economy is specific, and a bookkeeper who treats every business the same misses what matters in each. The city depends on the financial services economy along the Exchange Place waterfront, a dense restaurant and retail scene, the construction and real estate business driving Journal Square and Newport, healthcare around Jersey City Medical Center, and the professional services that sit alongside all of it. Here is what is genuinely different about the books in the ones we see most.

How we handle it

Financial services and consultancies. The Jersey City and Hoboken waterfront around Exchange Place holds roughly 19 million square feet of Class A office space, and Hudson County's financial-sector employment runs in the tens of thousands, which produces a steady layer of independent consultants, advisory shops, and back-office service firms. These books need clean revenue recognition on retainers and milestones, contractor versus employee classification handled correctly, and, for any firm with staff commuting in from outside the city, the Jersey City payroll tax carried properly.

Restaurants and food businesses. The daily reality is merchant deposits net of processor fees, tips flowing through payroll, and prepared food taxable at the full 6.625 percent even where a nearby zone retailer charges half on goods. We unwind deposits to gross sales so the books match the point of sale system, which is exactly the tie-out a New Jersey sales tax examiner runs.

Construction, trades, and real estate development. With Journal Square and Newport both building, job-level profit is the whole question. We track costs by job, carry work in progress correctly, and manage the New Jersey sales tax split the trades get examined on: a capital improvement is exempt when the customer signs a Form ST-8, repairs and maintenance are taxable, and New Jersey contractors pay tax to their supplier on materials in either case, which has to be costed to the job rather than treated as a recoverable.

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.

Landlords and real estate investors. Security deposits are not income and are held separately, every property gets its own profit and loss, and depreciation schedules stay current. In Hudson County the property tax line is large enough that the assessment itself deserves an annual look against the city's equalization ratio.

E-commerce and retail. 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. For a certified zone retailer, half-rate and full-rate sales are reported at different rates on the monthly UZ-50, so they stay separated in the books by design.

Professional services. Law, consulting, and design firms depend on unbilled work in progress and retainers. Attorney books add trust and IOLTA funds that must stay strictly separated from operating cash, and New Jersey partnerships carry a $150 per owner filing fee once there are more than two owners.

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 CPA licensed in New Jersey and New York 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.

Service 07

Jersey City and New Jersey resources for small business owners

The filings and registrations Jersey City owners most often ask about are spread across state, county, and city offices, each with its own site and its own rules.

How we handle it

The offices you will actually use: the New Jersey Division of Taxation for sales tax, the Corporation Business Tax, and the BAIT; the Division of Revenue and Enterprise Services for Form NJ-REG, LLC and corporation formation, and the annual report; the Jersey City Division of Taxation and the city's tax pages for the employer payroll tax and property tax; the Hudson County Clerk for trade name certificates and recorded documents; the New Jersey Urban Enterprise Zone program and the Jersey City Economic Development Corporation for zone certification and local programs; the U.S. Small Business Administration New Jersey District Office in Newark and the New Jersey Small Business Development Centers for free advisory; SCORE for volunteer mentoring; and the Hudson County Chamber of Commerce for the local business community. If a registration or filing on any of these sites is the thing blocking you, ask us; it is usually a ten minute answer.

What you get: A straight answer on which office handles the registration or filing that is blocking you.

FAQ

Frequently asked questions

How much do bookkeeping services cost in Jersey City, NJ?

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 Jersey sales tax returns?

Yes. We prepare and file the ST-50 quarterly returns and the ST-51 monthly payments where they apply, reconcile the 6.625 percent collected to the liability on the books, and keep the resale and exemption certificates that support nontaxed sales. If you are a certified Urban Enterprise Zone retailer we handle the monthly UZ-50 and keep the half-rate sales separated. If you are not yet registered, we handle the NJ-REG registration first.

Do you handle the Jersey City payroll tax?

Yes. The tax is 1 percent of quarterly gross payroll for employees who are not Jersey City residents, with an exemption under 2,500 dollars of quarterly payroll, and it cannot be withheld from wages. We keep the payroll records so the residency and work-location split supports the return, book the tax as an employer expense, and reconcile the quarterly filings to the payroll in your books.

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

Both. Corviniti prepares business returns (S corporations, partnerships, C corporations, Schedule C), the New Jersey 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.

Which accounting software do you use?

Most of the small businesses we work with are on QuickBooks Online, so that is where we keep the majority of our clients, and it is what we recommend when a business is choosing a platform. We also work in Xero, and for larger or more complex companies, NetSuite and Sage Intacct. If you are on desktop QuickBooks, spreadsheets, or a shoebox, migration to QuickBooks Online is part of the setup, and you keep full ownership of the file.

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 Jersey capital-improvement sales tax rules the trades get examined on. A capital improvement is exempt when the customer signs a Form ST-8, repairs and maintenance are taxable, and New Jersey contractors still pay sales tax to their supplier on materials either way, which is the part most job costing gets wrong. We work with the field service 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 6.625 percent even where a neighboring retailer charges the Urban Enterprise Zone half rate on goods. 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. If you are a certified retailer inside the Jersey City Urban Enterprise Zone, in-person sales at the half rate and everything else at the full rate have to be recorded separately, because the monthly UZ-50 a certified zone business files reports each at its own rate. We work with the platforms these businesses use, including Shopify, Amazon, Stripe, and Square.

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. In Jersey City that also means tracking basis and closing costs carefully, because New Jersey's graduated realty transfer fee on sales above $1 million is now paid by the seller and applies to the entire price. We work with the platforms these businesses use, including AppFolio, Buildium, and Yardi.
