We’ve built a streamlined workflow that integrates directly with your job site operations:
We review your current contractor agreements and payroll structure to ensure you are meeting federal and state labor requirements.
We set up secure portals for your subcontractors to submit tax info (W-9s) and invoices, creating a digital paper trail for every payment.
Our cloud-based systems categorize expenses by project, allowing you to see your "Work in Progress" (WIP) and cash flow in real-time.
We handle all quarterly estimated payments and year-end reporting, ensuring all contractors receive their forms and the IRS receives its due.



While the "Construction Industry Scheme" (CIS) is a UK-specific term, the US has similar requirements regarding Contractor Tax Withholding and 1099 Reporting. At BestFiler, we provide the US-equivalent services to ensure your construction business meets all IRS "Construction Industry" standards.
The IRS uses a "Right to Control" test. If you control how, when, and where the work is done, they may be an employee (W-2). If they provide their own tools and work independently, they are likely a contractor (1099). We help you make this determination to avoid massive back-tax penalties.
If a subcontractor fails to provide a valid Taxpayer Identification Number (TIN), the IRS requires you to withhold tax (currently 24%) from their payments. We manage this process for you, ensuring the funds are properly remitted to the IRS so you aren't held liable for the tax.
Yes. We assist in maintaining a clean record of your subcontractors' W-9 forms and can help track their insurance certificates to ensure you aren't exposed to unnecessary liability during a workers' comp audit.
