How do I account for subcontractor payments and ensure 1099 compliance on construction jobs?
Collect a W-9 from every subcontractor before you issue the first payment. Not after the first invoice. Not in January when you’re scrambling to file. Before you pay them anything. Make it part of your onboarding alongside the signed subcontract and insurance certificates. Store the W-9s digitally so you have the legal name, address, and tax ID ready when filing season arrives.
In QuickBooks Online, create a vendor record for each sub and enter the information from their W-9. Check the box that marks them as a 1099 vendor so QBO automatically tracks their total payments throughout the year. This takes a couple of minutes per sub and eliminates the January panic of chasing down tax IDs from people who may not return your calls.
Every payment to a sub needs to hit the correct project. If you’re running multiple jobs, a lump “subcontractor expense” account tells you nothing useful. Set up each project in QBO and assign sub invoices to the appropriate job when you enter them. This is the foundation of construction job costing and it’s how you know whether a project is actually profitable or just feels profitable because revenue is coming in.
Retainage requires its own tracking. When a sub invoices $10,000 and you hold 10% retainage, you pay $9,000 and record the remaining $1,000 as retainage payable. The full $10,000 hits the project cost when the work is performed, which keeps your job cost reports accurate. When you release the retainage after final inspection or project completion, you pay against that liability. If you just short-pay invoices without tracking retainage separately, your project costs will be understated and you’ll lose visibility into what you actually owe.
For 1099-NEC filing, any subcontractor you pay $600 or more in a calendar year must receive a 1099-NEC. The deadline to both file with the IRS and furnish copies to the subcontractor is January 31. If your vendor records are set up correctly and marked as 1099 eligible, QBO can generate and e-file them directly. The process is straightforward when the data is clean. It becomes a nightmare when vendor records are incomplete or payments weren’t coded properly.
The penalties for not filing are real. The 2024 rate is $310 per form you fail to file on time. For a general contractor working with 20 or 30 subs, that adds up to thousands of dollars for something that takes a few hours if your books are maintained throughout the year. If the IRS decides you intentionally ignored the requirement, there is no cap on the penalty amount.
One thing that trips up a lot of contractors is paying a sub through a personal account or cash and forgetting to record it. That payment still counts toward the $600 threshold, and the IRS can still penalize you for not reporting it. Run every sub payment through your business account so there is a clear trail. Having construction bookkeeping services handle this monthly means your vendor records stay current and nothing falls through the cracks at year-end.

More Questions
How do I set up job costing in QuickBooks Online for a general contractor?
Use sub-customers for each job, classes for cost categories like labor and materials, and enable the Projects feature for tracking. The chart of accounts needs to be structured for construction or the reports won't tell you anything useful.
Read answerHow do I calculate percentage of completion for revenue recognition on long-term contracts?
Use the cost-to-cost method. Divide total costs incurred to date by total estimated project costs to get your completion percentage, then multiply by the total contract price to determine earned revenue. Update your cost estimates monthly because they will change.
Read answerWhat insurance costs should a contractor track by job versus as overhead?
General liability and workers comp premiums tied to job payroll should be allocated per job. Builder's risk and project-specific bonds are direct job costs. General commercial policies, office insurance, and bonding capacity costs are overhead.
Read answerHow do I track equipment costs per construction job including depreciation and fuel?
Calculate an internal equipment rate that bundles depreciation, maintenance, insurance, and fuel into a single hourly cost. Multiply that rate by the hours each piece of equipment works on a job to allocate costs accurately.
Read answerHow should I handle change orders in my construction job costing system?
Track each change order as an amendment to the original contract. Update the total contract value and revised cost estimate in your WIP schedule, and keep unapproved change orders separate until the client signs off.
Read answerHow do I track retainage in QuickBooks for construction projects?
QuickBooks Online doesn't have a built-in retainage feature. You need to create a Retainage Receivable account and a Retainage Payable account, then use line items and journal entries at each billing cycle to track what's being withheld.
