A quick, no-jargon guide to what taxes are and how to actually pay them.
A tax is money you're legally required to pay to the government — federal, state, or local. The government uses that money to pay for things like roads, schools, police, the military, parks, and programs like Social Security and Medicare.
If you earn money, buy stuff, or own property, you're almost always paying some kind of tax — sometimes without even noticing.
Nobody is taking taxes out of that money for you. A safe rule of thumb: set aside ~25–30% of every side-gig payment in a separate savings account so you have it ready at tax time.
If you'll owe more than $1,000 for the year, the IRS wants you to pay quarterly estimated taxes (April, June, September, January) instead of waiting until April.
