Warren County businesses ## Who we work with here The county seat is Belvidere. Businesses we see across the county include farms and farm markets, trucking and warehouse related businesses near Phillipsburg and Hackettstown, contractors, and small town shops. A rural county with some industrial sites means a mix of agriculture, trades and small shops, each with its own bookkeeping needs. ### What we handle - Monthly bookkeeping and bank and card reconciliation - Cleanup when the books are months behind - Monthly profit and loss and balance sheet - Payroll and New Jersey filing support, as an add-on - Sales tax and annual report reminders Local facts ## Warren County at a glance Population 109,632 (2020 census) County seat Belvidere Largest municipalities Phillipsburg (15,249 in 2020) by population and Hardwick Township by area Schools Centenary University and Warren County Community College Economy A 2021 gross domestic product of about $3.7 billion, the smallest of the state's 21 counties; most of the county is in the Warren Hills American Viticultural Area, with five active wineries Source: [Wikipedia, Warren County, New Jersey](https://en.wikipedia.org/wiki/Warren_County,_New_Jersey), read October 2026. Figures change and describe the county, not our clients. Warren County at a glance ## Warren County by the numbers Warren County had about 109,632 residents in the April 1, 2020 estimates base, 19th of New Jersey's 21 counties and about 1.2% of the state's 9,288,994 people. That makes it one of the smaller counties in the state. In a smaller county, word of mouth carries a lot of weight, and owners often wear many hats, which is when bookkeeping slips.

Bookkeeping notes ## What the books look like for Warren County businesses like these ### Contractors and trades Materials, subcontractors and labor are coded to the job, so each job's margin is visible before the next bid. Deposits and progress billings are recorded as they happen, and 1099 details for subcontractors are collected up front. General bookkeeping practice, not tax or legal advice. Beyond the books ## From records to decisions Some owners are happy with accurate books. Others, in Warren County and elsewhere, reach a point where they need forecasts, margins and a plan, but do not need a full-time finance executive. Fractional CFO support is a few hours a month of senior financial attention instead of a full-time hire. It sits on top of your monthly books. For tax returns, audits or legal questions we work alongside your CPA or attorney, and we are not a CPA firm. ### What that can include - A rolling 13-week cash flow forecast, so a slow month is not a surprise - Financial statements and a package built for a bank or lender - Cash planning around estimated tax dates, coordinated with your CPA [See how the planning layer works →](/bookkeeping/guides/what-is-a-fractional-cfo) New Jersey items ## What Warren County businesses deal with Sales tax, quarterly payroll reports, the annual report and 1099-NEC forms are the same statewide.

FAQ ## Warren County bookkeeping questions **Do you work with Warren County businesses?** Yes. Everything is online, in accounting software you own, so the distance from Cranford to Belvidere does not matter. We have no office in Warren County. **How do seasonal farm and producer businesses stay organized?** Income arrives in bursts, so a monthly cash flow view matters more than the yearly total. Seed, feed and supply purchases are tracked by season, farm stand and wholesale sales are separated, and equipment is recorded with its financing. **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. **Do you handle New Jersey payroll and sales tax for Warren 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. ### Neighboring counties - [Sussex County](/bookkeeping/new-jersey/sussex-county) - [Morris County](/bookkeeping/new-jersey/morris-county) - [Hunterdon County](/bookkeeping/new-jersey/hunterdon-county) [All New Jersey counties](/bookkeeping/new-jersey) · [Northeast](/bookkeeping/northeast) · [Bookkeeping by software](/bookkeeping/software) · [Bookkeeping guides](/bookkeeping/guides) · [Pricing](/bookkeeping/#pricing) Warren County property taxes ## Property tax figures for Warren County owners and landlords Property tax on a Warren County building depends heavily on which of the county's 22 municipalities it sits in. From the State's 2025 tables: General tax rate range 2.620 in White Township to 5.890 in Washington Borough per $100 of assessed value (a spread of 3.270) Average residential tax bill $5,256 in Phillipsburg Town to $11,080 in Greenwich Township; the middle town is $8,506 Assessments compared with market value town average ratios from 46.82% (Washington Borough) to 76.8% (Belvidere Town); 22 of 22 towns are under 85% Appeals Warren County Board of Taxation, Cummins Building, 202 Mansfield Street, Belvidere, NJ 07823, (908) 475-6071. 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.
