How to Keep Track of Side-Gig Income (and Be Ready for Tax Time)
Picture a person with three side gigs: a few evenings of delivery driving, some weekend lawns, and a little Etsy shop. Each one pays into a different account at a different time. In April, they are digging through app screens and old bank statements trying to work out what they earned.
A small habit avoids that scramble. This article is general information, not tax advice. For your situation, talk to a tax preparer or read the IRS guidance for self-employed people at irs.gov.
Why the log matters
Money you earn from side work is generally income, even when no company sends you a tax form. The IRS has a page for self-employed people covering how to report it. If you are paid as a contractor, you also usually owe self-employment tax on top of regular income tax, and many people make estimated payments during the year rather than one large payment at the end. The rules depend on how much you earn and your circumstances, so check with a professional.
What all of that has in common is that it starts with good records. If you know what came in, you can work out what you owe. If you know what you spent, you may be able to deduct some of it.
Log daily, and keep it tiny
A record you will actually keep is better than a perfect one you skip. For each gig, each day you work, write down two things:
- Hours worked
- Dollars earned
That's it. Doing it the same evening takes about a minute. Waiting until the weekend means guessing, and guessing is where errors creep in.
Keep each gig separate
Give every stream of income its own name: "Uber," "lawns," "Etsy," "tutoring." When each has its own line, you can see which one pays the best per hour. Someone who thinks delivery is their best gig may find that lawns earn double per hour once driving costs are counted.
Track expenses too
Income is only half the picture. Save receipts or make a note when you buy supplies, pay a platform fee, or put gas in the car for work. Photos of receipts on your phone are fine. A separate bank account or card for gig money makes it much easier to tell business spending from personal.
Put some money aside
When nobody withholds taxes for you, it is easy to spend money you will owe later. Many self-employed people move a percentage of each payment into a separate savings account. The right percentage depends on your income, so ask a tax preparer, and start with a cautious guess if you are unsure.
Review weekly, then monthly
Once a week, look at your totals. Which gig earned the most? Which took the most hours? At month's end, compare against your goals. You will start making decisions based on real data, like dropping a low-paying gig or booking more of the best one.
Back it up
If your log is on a phone, keep a copy somewhere else. Export it now and then and save it in your email or cloud storage.
