Why do contractors need a specialized CPA?

Contractors have accounting needs that generic bookkeepers miss: job costing that ties revenue to specific projects, work-in-progress tracking, equipment depreciation, and mileage deductions across multiple job sites. A CPA who understands construction accounting ensures your books reflect true job profitability and your deductions are captured correctly.

What is job costing and why does it matter for contractors?

Job costing assigns every cost, labor, materials, subcontractors, equipment, and overhead, to a specific project so you can see the true profit margin on each job. Without it, you may be winning bids but losing money on individual projects. We set up job costing in QuickBooks so you can price future bids from real data, not guesses.

Can a contractor elect S corp status?

Yes, and it often makes sense once your net profit consistently exceeds roughly $60,000-$80,000. The S corp election splits your income into a reasonable salary and distributions, saving on self-employment tax. We analyze your numbers, handle the election, and set up payroll so your reasonable compensation is defensible.

How do equipment depreciation and mileage deductions work for contractors?

Equipment can be expensed immediately under Section 179 or depreciated over its useful life, depending on your tax strategy. Vehicle use for business is deductible at the IRS standard mileage rate or as actual expenses. We track both so you capture every deduction while staying audit-ready with proper documentation.

Do you provide QuickBooks support for contractors?

Yes. We set up and clean up QuickBooks files specifically for construction, configuring job costing, item lists, and class tracking, and provide ongoing monthly bookkeeping so your file stays current and your tax return is prepared from accurate numbers.
