Everything You Should Know About the 1099 Form Deadlines and Taxes

If you worked as a freelancer, independent contractor, or side hustler during the year, you'll likely receive a 1099 form. This form reports your non-employee compensation to the IRS and is essential for tax filing. Understanding the deadlines, structure, and tax impact of a 1099 is key to staying compliant.

Key 1099 Filing Deadlines (2025-2026)

What Is a 1099 Form?

The 1099 is a series of IRS forms used to report income earned outside of traditional employment. The most common is the 1099-NEC (Non-Employee Compensation), used to report earnings over $600 paid to independent contractors. Other types include 1099-MISC, 1099-INT, 1099-DIV, and more.

Do You Need to Pay Taxes on a 1099?

Yes. Unlike W-2 income, taxes are not automatically withheld from 1099 income. You're responsible for estimating your total income and filing accordingly. This includes federal income tax, state tax (if applicable), and self-employment tax (Social Security & Medicare).

Common Mistakes to Avoid with 1099 Filing
