Bookkeeping for Kentucky Contractors

A Kentucky contractor and home-service bookkeeping guide covering chart of accounts, job costing, sales tax distinctions, retainage, subcontractors, and month-end review.

Short answer

Contractor and home-service bookkeeping needs more than income and expense categories. It should track job income, labor, materials, subcontractors, equipment, retainage where applicable, sales tax treatment, W-9s, payroll, and monthly project profitability.

Checklist

  • Build a chart of accounts that separates direct job costs from overhead.
  • Track labor, materials, subcontractors, equipment, permits, and disposal by job when useful.
  • Collect W-9s and insurance records from subcontractors before payment.
  • Review Kentucky contractor-versus-retailer sales tax treatment before invoicing.
  • Set up retainage accounts if contracts hold back payment.
  • Review job profitability and balance sheet accounts every month.

Common mistakes

  • Judging jobs only by revenue instead of gross profit.
  • Mixing subcontractors, employee labor, materials, and overhead together.
  • Using resale assumptions for Kentucky contractor purchases without reviewing DOR guidance.
  • Ignoring retainage, deposits, and old receivables on the balance sheet.

Examples for service businesses

  • A remodeler should separate materials, subs, permits, disposal, and payroll by project where practical.
  • A home service company should reconcile merchant deposits, payroll, and vehicle costs monthly.
  • A landscaping contractor should review taxable services, materials, and project profitability together.

Build the right account structure

Contractors usually need direct cost categories for materials, subcontractors, direct labor, equipment, fuel, permits, and disposal. Overhead should stay separate so gross profit is visible.

The chart of accounts should be detailed enough to price work better, but not so detailed that every transaction becomes a debate.

Track projects where it matters

QuickBooks says projects can group transactions, estimates, and expenses for a single customer so the business can monitor profitability. QuickBooks Online Plus and Advanced support project tracking.

Project tracking only works if invoices, bills, expenses, payroll, and subcontractors are consistently assigned to the right job.

Watch Kentucky sales tax distinctions

Kentucky DOR explains that contractors can be treated as consumers of materials and certain taxable services used in real-property work. DOR also says contractors may not claim resale exemption for taxable landscaping or janitorial services performed on construction projects.

This distinction is why contractor bookkeeping should separate contractor work, retail sales, taxable services, materials, and use tax questions.

Close jobs and months

At month end, review open receivables, deposits, retainage, unpaid subcontractor bills, payroll allocations, and project gross margin. A job can look profitable before late bills or labor costs are posted.

When project reports and financial statements are reviewed together, pricing and cash decisions get better.
