Bookkeeping and Tax Services for Onslow County Businesses

Local bookkeeping, tax, and accounting support for small businesses across Onslow County. Clean books and tax-ready records from a Jacksonville-based firm.

Accounting for Onslow County

GMJ Accounting is based on Ellerbe Court in Jacksonville, so Onslow County is home for us. We provide bookkeeping, tax and consulting services to small businesses across the county, from operations near Camp Lejeune to coastal businesses in Sneads Ferry and Swansboro to shops and offices throughout Richlands and Holly Ridge.

Onslow County has a business mix that reflects its geography and its connection to the Marine Corps. Contractors who serve the base. Restaurants and retail along Western Boulevard and Lejeune Boulevard. Coastal hospitality and fishing-related operations. Service companies supporting military families. Each one has different bookkeeping needs, and we’ve worked with most of them.

Full-Service Bookkeeping

Monthly transaction categorization, bank and credit card reconciliation, and financial statements. Your books stay current and your records stay tax-ready throughout the year.

Catch-Up Bookkeeping

Months or years behind? We organize the backlog, correct prior errors, and get your records current. Most clients start here before moving into ongoing monthly work.

Business Tax Returns

Federal and North Carolina returns prepared by an Enrolled Agent. Because we keep the books all year, the return process is a clean handoff instead of a last-minute scramble.

Construction Job Costing

For Onslow’s many contractors, we track labor, materials, and subcontractor costs by project so you can see real profitability and bid future work with confidence.

Onslow County Businesses We Support

The county supports a wide range of small business activity. Camp Lejeune drives a steady demand for trades, services, and retail. The coastline brings seasonal restaurants, charter operations, and rental management. Jacksonville itself has a strong base of medical offices, professional services, and family-owned shops that have served the area for years.

We work with owners doing roughly $100k to a few million in annual revenue. Operations that have grown past the spreadsheet stage but aren’t ready to hire a full-time bookkeeper. That’s where we fit in.

Contractors and Trades

HVAC, electrical, plumbing, general contractors, and home services working throughout the county. Job costing, payroll, and clean records that hold up to lender or bonding review.

Restaurants and Hospitality

From Jacksonville staples to coastal seafood spots, we handle the daily transaction volume, tip reporting, and cost tracking that food and beverage businesses need to keep margins where they should be.

Medical and Dental Practices

Clinics, dental offices, chiropractors, and therapy providers across Jacksonville and the surrounding towns. We reconcile insurance receivables to actual deposits so the books reflect what really came in.

Retail and Professional Services

Shops, salons, agencies, and offices serving Onslow residents and military families. Sales tax tracking, payroll, and monthly reporting that gives owners a clear picture of the business.
