Employee vs. Independent Contractor Classification Guide for Nonprofits

Misclassifying a worker as an independent contractor when they should be on payroll is one of the most common and costly compliance mistakes nonprofits make. It triggers IRS back taxes, penalties, potential disallowance of grant costs under 2 CFR 200.430, and retroactive benefits liability — often discovered years after the fact during an audit.
