How much does accounting cost for contractors?
Monthly bookkeeping for contractors typically costs $300 to $800 depending on how many transactions you run and how complex your jobs are. A one-person operation doing 10 residential jobs a year pays less than a general contractor managing three crews across 40 active projects.
The pricing depends on transaction volume. More bank and credit card transactions mean more time reconciling and categorizing. Multiple jobs running simultaneously mean more time allocating costs to the right projects. Subcontractors to track, equipment to depreciate, and payroll to process all add complexity that affects cost.
Tax preparation for contractors runs $800 to $2,500 annually depending on your entity structure and how complicated your return is. Sole proprietors with Schedule C pay less than S-corps needing corporate returns plus owner K-1s. Multiple business entities, rental properties, or complex equipment depreciation schedules increase preparation time and cost.
Some firms charge hourly at $150 to $250 per hour. Others use flat monthly rates that include bookkeeping, tax planning, and preparation. Flat rates work better for budgeting but only make sense if the accountant understands your business well enough to price accurately upfront.
Construction accounting costs more than generic bookkeeping because it requires job costing setup, progress billing knowledge, and understanding contractor-specific tax issues. Someone charging $200 monthly for basic bookkeeping probably isn’t equipped to handle construction properly. You’ll end up with books that don’t show job-level profitability and tax returns that miss deductions.
The real cost comparison isn’t accountant fees versus doing it yourself. It’s accountant fees versus the cost of wrong numbers, missed deductions, and poor business decisions based on incomplete financial data. Most contractors who try DIY bookkeeping eventually need cleanup work that costs more than hiring help from the start would have.
