Accounting & Tax
For Contractors in California

Image by benjamin lehman

Running a contracting business in California means juggling job sites, crews, materials, permits—and taxes. Whether you're a general contractor, architect, electrician, plumber, or remodeler, your financial systems need to be just as strong as your framing. At Steve CPA, we specialize in helping construction professionals streamline their accounting, stay compliant, and minimize tax burdens.

Why Contractors Need Specialized Accounting

Construction accounting isn’t like other industries. You deal with:

  • Project-based income

  • Variable labor and material costs

  • Progress billing

  • Sales and use tax complexities

  • Work-in-progress (WIP) reporting

  • Percentage-of-completion revenue recognition

Without proper systems, you risk underbilling, overpaying taxes, or losing track of profitability. We help you avoid those pitfalls with tailored solutions built for contractors.

QuickBooks Setup & Job Costing That Works

Job costing is the backbone of construction profitability. We’ll help you set up QuickBooks Online or Desktop to:

✅ Track income and expenses by job
✅ Allocate labor, materials, and subcontractor costs accurately
✅ Create estimates and progress invoices
✅ Generate job profitability reports in real time

Sales & Use Tax in California: What Contractors Must Know

California contractors face unique tax rules:

  • Materials vs. Fixtures: Materials you install may be taxable at purchase; fixtures may require sales tax collection at installation.

  • Seller’s Permit: If you sell or lease tangible property (e.g., cabinetry, HVAC units), you may need to collect and remit sales tax.

  • Contract Type Matters: Lump sum vs. time-and-materials contracts affect your tax obligations

We help you navigate CDTFA regulations, structure contracts properly, and stay audit-ready.

Work-in-Progress (WIP) Accounting

WIP accounting tracks costs and revenue as work is performed—not just when a job is complete. This is critical for:

  • Accurate financial statements

  • Cash flow forecasting

  • Billing accuracy

  • Project monitoring and risk management

We prepare detailed WIP schedules that align with your project milestones and help you avoid overbilling or underbilling issues.

Percentage-of-Completion Revenue Recognition

For long-term projects, the IRS and GAAP require revenue to be recognized as work progresses. We use the cost-to-cost method to:

  • Calculate percent complete

  • Recognize revenue and expenses monthly

  • Adjust for change orders and scope shifts

This method gives you a more accurate picture of profitability and helps you stay compliant with tax laws.

 

Additional Services for Contractors

  • Bookkeeping & Payroll: Clean books and compliant payroll for crews and subs

  • Entity Structuring: Business structure review for tax efficiency

  • Cash Flow & Budgeting: Forecasting tools to keep your business solvent and scalable
