Tax documents for construction and trade contractors
Contractors have a lot of moving parts: job income, materials, subcontractors, tools and vehicles. Good records make the return, and your job costing, much easier.
Income documents
- Invoices and payment records for each job
- 1099-NEC and 1099-MISC forms received from customers or general contractors
- Retainage or deposits received but not yet earned
- Bank deposit records
Expenses and receipts
- Materials receipts, tied to jobs where possible
- Subcontractor invoices and payments, with a W-9 on file for each
- Tool and equipment purchases with invoices
- Vehicle and fuel records
- Insurance, bonding and license fees
- Equipment rental and permit costs
- Employee payroll reports, if applicable
Other records to gather
- 1099-NEC filings you issued to subcontractors
- Vehicle mileage log
- Estimated tax payment confirmations
- Loan and equipment financing statements
- Year-end list of work in progress and unpaid invoices
Common mistakes to avoid
- No W-9 from subcontractors, which makes 1099 filing painful
- Personal purchases mixed with job materials
- Not tracking retainage and deposits correctly
- Missing receipts for small tool purchases
Frequently asked questions
Why do I need a W-9 from subcontractors?
It gives you the name and tax ID you need to report payments to them, so collect it before you pay.
Should materials be tied to specific jobs?
Job-level tracking helps you see profit per job and supports cost reporting, even if the tax return only needs the total.
