A Quick Story-Style Example

Imagine you start a freelance design side‑gig on January 2, 2026.
By March 31, 2026, you’ve earned a few thousand dollars with no tax withheld. Because you expect to owe more than the IRS threshold in taxes for the year, you estimate your tax for that income and send in your Q1 payment by April 15, 2026 to avoid underpayment penalties.

It’s the same rhythm most self‑employed people follow: earn in Q1, pay around mid‑April.
