What are the IRS rules for employee reimbursements in a construction company?

March 27, 2026

Under IRS accountable plan rules, employee reimbursements must have a business purpose, be substantiated with receipts, and have any excess returned within a reasonable time. Platforms like Vergo address this by capturing receipts at the point of spend and linking each reimbursement to a specific job cost code for audit-ready documentation. Without these controls, reimbursements become taxable wages.

The Compliance Context

Construction companies are subject to strict IRS regulations around employee reimbursements. The IRS requires companies to operate an "accountable plan" to avoid having reimbursements classified as taxable income. This means having a formal policy that meets specific requirements for documentation, business connection, and timely expense reporting.

Construction companies face heightened audit risk due to the large volumes of reimbursable expenses, from fuel and materials to per diem and mileage. Auditors scrutinize reimbursement practices to ensure they align with IRS rules and don't result in underreported taxable income.

Risks of Non-Compliance

Tax reclassification of reimbursements as taxable income, with penalties and back taxes owed
Lien exposure if reimbursements are not properly documented as "cost of goods sold"
Distortion of work-in-progress reporting if reimbursements are not tracked accurately
Audit findings and penalties for insufficient documentation or policy violations
Damaged employee trust and morale from inconsistent reimbursement practices

Best Practices

Establish a formal accountable reimbursement plan that meets IRS requirements.
Require employees to submit timely expense reports with detailed receipts and business purpose.
Integrate reimbursement policies and workflows into your construction management software.
Implement automated policy enforcement, receipt imaging, and audit trail features.
Conduct periodic audits of reimbursement practices and adjust policies as needed.
Train all employees on reimbursement policies and proper documentation.
Leverage technology to streamline and centralize the reimbursement process.

How Vergo Helps

Vergo is a card-agnostic expense management platform built for construction. Connect any corporate or project credit card and get full visibility and control over field spending.

Job-cost coding at the point of capture — field teams assign job number, cost code, and cost type from their mobile device before the receipt leaves the job site.
Per-job spend controls — set card limits by project, cost code, or cardholder so spending stays within approved budgets.
Mobile receipt capture — superintendents and PMs photograph receipts on-site with automatic data extraction.
Role-based approval workflows — route expenses through project managers, job-level approvers, and controllers based on your org structure.
Vergo integrates natively with major construction ERPs, syncing coded expenses directly into job cost and general ledger without manual re-entry.

Frequently Asked Questions

How do I prepare for a construction company reimbursement audit?

Key steps include: documenting your accountable plan policy, maintaining detailed expense reports and receipts, training employees on reimbursement requirements, and using construction software to enforce compliance.

What should a construction reimbursement policy include?

At minimum, your policy should cover eligible expenses, documentation requirements, approval workflows, reporting timelines, and consequences for non-compliance. Integrating the policy into your construction management software is crucial.

How can technology help with reimbursement compliance?

Construction software like Vergo can automatically enforce policy rules, require receipts, track audit trails, and generate compliance reports - reducing the manual effort and risk of errors.

What are the tax implications of non-accountable reimbursements?

Reimbursements made outside of an IRS-compliant accountable plan must be reported as taxable income to employees, leading to tax liabilities, penalties, and strained employee relations.
