How Thumbtack earnings are taxed
Thumbtack contractors are considered self-employed, which means you'll pay both self-employment tax and regular income tax on your net earnings. This is different from W-2 employees who only see half of Social Security and Medicare taxes on their paystub.
You'll receive a 1099-NEC form from Thumbtack if you earned $600+ during the tax year. This reports your gross earnings before Thumbtack's service fees are deducted.
Example: $25,000 in Thumbtack earnings
Let's say you earned $30,000 in customer payments through Thumbtack, but paid $5,000 in platform fees, netting you $25,000.
