Middlesex County by the numbers
Middlesex County had about 863,162 residents in the April 1, 2020 estimates base, 3rd of New Jersey's 21 counties and about 9.3% of the state's 9,288,994 people. That makes it one of the larger counties in the state.
A larger customer base usually means more competition for the same local work, so clean books and quick quotes matter.

Bookkeeping notes
What the books look like for Middlesex County businesses like these
Shops and retailers
Point-of-sale totals are matched to deposits, inventory purchases are separated from operating costs, and sales tax is tracked by period. A monthly inventory and gross margin check shows which lines actually pay.
General bookkeeping practice, not tax or legal advice.
Beyond the books
More than books: planning and cash
Some owners are happy with accurate books. Others, in Middlesex County and elsewhere, reach a point where they need forecasts, margins and a plan, but do not need a full-time finance executive.
It is planning and reporting on the books we keep, delivered at the size your business needs. It does not replace your CPA. Tax returns are a separate service (see /tax-preparation); we do not audit statements or give legal advice.
What that can include
- A rolling 13-week cash flow forecast, so a slow month is not a surprise
- A one-page dashboard of the five or six numbers you steer by
- Hiring and equipment decisions modeled before you commit

FAQ
Middlesex County bookkeeping questions
Do you work with Middlesex County businesses?
Yes. Everything is online, in accounting software you own, so the distance from Cranford to New Brunswick does not matter. We have no office in Middlesex County.
What do logistics and wholesale businesses watch in their books?
Fuel, tolls, insurance and equipment costs are tracked per vehicle or per route, customer invoices are aged so slow payers are visible, and inventory in transit is recorded at the right time. Owner-operators get a clean split between business and personal costs.
How should a restaurant or food business keep its books?
Daily sales, tips, delivery-app payouts and card fees all land in the bank differently, so each is reconciled on its own. Food and beverage cost is tracked monthly against sales, and sales tax collected is kept apart from revenue.
Do you handle New Jersey payroll and sales tax for Middlesex County businesses?
We can prepare and file New Jersey payroll reports and sales tax filings as an add-on, along with annual report and renewal reminders. Government fees are extra, and we confirm your filing schedule on your own state account first.
How much does it cost?
Monthly bookkeeping starts at $450 for the smallest tier and rises with transaction volume. The bookkeeping page has a live estimate, and we confirm a written quote before starting.

Middlesex County property taxes
Property tax figures for Middlesex County owners and landlords
Property tax on a Middlesex County building depends heavily on which of the county's 25 municipalities it sits in. From the State's 2025 tables:
- General tax rate range
- 1.568 in Carteret Borough to 12.177 in East Brunswick Township per $100 of assessed value (a spread of 10.609)
- Average residential tax bill
- $7,101 in New Brunswick City to $13,819 in Metuchen Borough; the middle town is $9,597
- Assessments compared with market value
- town average ratios from 17.28% (Woodbridge Township) to 112.87% (Carteret Borough); 20 of 25 towns are under 85%
- Appeals
- Middlesex County Board of Taxation, County Administration Building, 75 Bayard Street, 4th Floor, New Brunswick, NJ 08901, (732) 745-3350. Deadline: April 1, or May 1 after a town-wide revaluation or reassessment. Property assessed over $1,000,000 may go straight to the Tax Court.
A ratio well under 100% means assessments there sit below market value, so the general rate looks higher than the real burden; compare towns by the effective rate. Budget with your own bill, not these averages. Estimate a bill.
