Calculating True Net Income From Side Hustles
Launching a secondary income stream—such as e-commerce selling, freelance consulting, tutoring, or crafting—provides extra cash flow. However, many side hustlers overestimate their earnings by looking strictly at top-line revenue deposits without deducting cost of goods sold (COGS), payment processing fees, and self-employment tax liabilities.
Quarterly Estimated Tax Requirements
In the US, if you expect to owe more than $1,000 in federal taxes from your 1099 side hustle income, the IRS requires filing Quarterly Estimated Taxes (Form 1040-ES) in April, June, September, and January to avoid underpayment interest penalties.
