Why do plumbers need a specialized CPA?

Plumbing businesses have accounting needs that generic bookkeepers miss: job costing that tracks parts, labor, and travel time to each service call or installation, vehicle and mileage deductions across multiple daily job sites, parts and supplies inventory, and S corp elections that reduce self-employment tax. A CPA who understands the plumbing trade ensures your books reflect true job profitability and your tax strategy captures every trade-specific deduction.

How do you handle emergency service call accounting?

Emergency service calls create unique accounting challenges, after-hours rates, dispatch fees, and materials used on-site must all be tracked to the specific job. We set up QuickBooks to capture service call revenue and costs by job type (emergency, routine, installation, new construction) so you can see which services are most profitable and price accordingly.

Can a plumber benefit from an S corp election?

Yes, once your net profit consistently exceeds roughly $60,000-$80,000, electing S corp taxation can save thousands per year by splitting income into a reasonable salary and distributions. We analyze your numbers, handle the election, set up the required payroll, and ensure your reasonable compensation is properly documented.

How do parts and supplies tracking work for plumbers?

Plumbers buy parts from supply houses, keep inventory in vans, and use materials on jobs. We set up inventory tracking that accounts for parts purchased, parts in stock, and parts used on specific jobs. This ensures your cost of goods sold is accurate and your job margins reflect the true cost of materials, not just the invoice amount.

What deductions are specific to plumbing contractors?

Plumbing-specific deductions include vehicle expenses (vans and trucks used for business), tools and equipment (Section 179 or depreciation), parts and supplies, continuing education and licensing fees, uniform and safety equipment, and cell phone costs. We ensure every applicable deduction is tracked and claimed, reducing your taxable income.
