Expense Reimbursement Policies for Independent Contractors

The Expense Question in Contractor Relationships

One of the distinguishing features of an independent contractor relationship is that the contractor typically bears their own business expenses. Unlike employees, who are often reimbursed for work-related costs, contractors generally build expenses into their rates.

However, some contractor engagements legitimately involve expenses that should be reimbursed by the client, particularly when the contractor incurs costs specifically at the client's request or for the client's benefit. Getting the expense reimbursement terms right protects both parties and helps maintain the independent contractor classification.

When Expense Reimbursement Is Appropriate

Client-Directed Expenses

Expenses that the client specifically requests or requires the contractor to incur are the most appropriate candidates for reimbursement:

• Travel to the client's location for required meetings or on-site work
• Specific software licenses or subscriptions required by the client
• Materials or supplies specified by the client for the project
• Third-party services procured on the client's behalf (printing, stock photography, domain registrations)

Project-Specific Expenses

Costs directly tied to the specific project that go beyond the contractor's normal business overhead:

• Research materials, data access, or specialized databases
• Prototype materials or testing equipment
• Shipping and delivery of physical deliverables
• Project-specific insurance requirements

When Not to Reimburse

Expenses that are part of the contractor's normal business operations should typically not be reimbursed, as doing so can weaken the independent contractor classification:

• General office supplies and equipment
• Standard software tools the contractor uses across all clients
• Internet and phone service
• Professional development and training
• General liability insurance
• Home office costs

Structuring Expense Terms in the Agreement

Eligible Expense Categories

List the specific categories of expenses that are eligible for reimbursement. Being explicit prevents disputes and sets clear expectations:

Travel expenses:

• Airfare (economy class unless otherwise approved)
• Ground transportation (rental car, rideshare, taxi)
• Mileage for personal vehicle use (specify the rate, such as the IRS standard mileage rate)
• Lodging (with per-night limits)
• Meals (with per diem or per-meal limits)
• Parking and tolls

Project materials:

• Specific materials purchased for the project
• Third-party services procured on behalf of the client
• Shipping and delivery costs
• Printing and production costs

Technology:

• Client-required software licenses
• Cloud hosting or computing costs specific to the project
• Domain registrations or service subscriptions purchased for the client

Spending Limits

Set clear financial boundaries:

• Per-item limits: Maximum amount for individual expenses without prior approval (such as $100)
• Category limits: Maximum amounts per category per month or per project
• Project budget: Total expense budget for the entire engagement
• Pre-approval thresholds: Dollar amount above which prior written approval is required

Pre-Approval Requirements

Specify which expenses require advance approval:

• All travel arrangements
• Individual expenses above a specified threshold
• Recurring subscriptions or commitments
• Capital expenditures or equipment purchases
• Expenses outside the listed categories

Define how approval requests should be submitted and who has the authority to approve them.

Documentation and Submission

Required Documentation

Specify what documentation the contractor must provide for each expense:

• Receipts: Original receipts or clear copies for every expense above a minimum threshold (such as $25)
• Description: Brief explanation of the business purpose of each expense
• Date: When the expense was incurred
• Project reference: Which project or task the expense relates to
• Approval reference: Reference to any pre-approval, if applicable

Expense Report Format

Provide a standardized format or template for expense submissions. Include:

• Required fields and layout
• How to categorize expenses
• How to attach supporting documentation
• Where to submit expense reports

Submission Deadlines

Set deadlines for expense report submission:

• Monthly submission deadlines (such as the 5th of the following month)
• Final submission deadline after project completion (such as 30 days after the last day of the engagement)
• Consequences of late submission (delayed reimbursement or forfeiture)

Reimbursement Process

Payment Timeline

Specify when the contractor can expect reimbursement:

• Net 15 or net 30 from receipt of a complete and approved expense report
• Whether expenses are paid with regular invoiced payments or separately
• How disputed expenses are handled pending resolution

Payment Method

Clarify how reimbursements are paid:

• Added to the next regular invoice payment
• Separate payment via check, ACH, or wire transfer
• Through the same payment method as project fees

Disputed Expenses

Establish a process for handling expense disputes:

• How the client notifies the contractor of disputed expenses
• The contractor's right to provide additional documentation or explanation
• How long the contractor has to respond to disputed expenses
• What happens if the dispute can't be resolved

Tax Implications

For the Hiring Company

Reimbursed expenses under an accountable plan (with adequate documentation and a business connection) are generally not reported on the contractor's 1099-NEC. However, if expenses are reimbursed without adequate documentation or without a business connection, they may be treated as additional compensation.

For the Contractor

Properly reimbursed expenses are not income to the contractor and should not be included on their tax return. Unreimbursed business expenses may be deductible on the contractor's Schedule C.

Maintaining Records

Both parties should maintain expense records for at least three years (seven years is safer) for tax audit purposes. The IRS may require substantiation of expenses that were reimbursed.

Expense Caps and All-Inclusive Pricing

All-Inclusive Rate

Some contractor relationships use an all-inclusive rate where the contractor's fee covers all expenses. This approach:

• Simplifies administration (no expense reports, no reimbursement process)
• Gives the contractor full control over how they allocate their budget
• Supports the independent contractor classification (the contractor bears their own expenses)
• Requires the contractor to accurately estimate expenses when setting their rate

Hybrid Approach

A common middle ground is to build standard expenses into the contractor's rate but reimburse extraordinary or client-directed expenses separately. This might mean:

• The contractor's rate covers normal business overhead
• Travel expenses requested by the client are reimbursed separately
• Project-specific materials are reimbursed upon approval
• The agreement clearly delineates the line between included and reimbursable expenses

Classification Implications

How you handle expenses can affect worker classification:

Supports contractor status:

• Contractor covers their own standard business expenses
• Reimbursement is limited to client-directed or project-specific costs
• Contractor has discretion over how they spend their own business funds

May suggest employment:

• Company reimburses all of the contractor's business expenses
• Company provides equipment, supplies, and tools
• Company covers the contractor's insurance, training, and professional development
