Tracking Tips and Cash Income — Why the IRS Cares and How to Stay Clean

Tips and under-the-table cash count as taxable income. Here's how the IRS sees it, what your employer is required to do, and a simple system any tipped or cash-paid worker can use to stay out of trouble.

If you earn tips at a restaurant or salon, get cash for side work, or pick up babysitting and handyman gigs paid in cash, the IRS considers all of it taxable income. The fact that no one issued you a 1099 or W-2 for it doesn't make it invisible — and the penalties for unreported income can compound quickly.

What the IRS actually expects

IRS Publication 531 covers tip reporting. The general rule for traditionally tipped workers (servers, bartenders, hairstylists):

• Keep a daily record of cash tips, charged tips, and tips you paid out to others (e.g., tip-outs to bussers or barbacks).
• If you receive $20 or more in tips in a single month from one employer, you generally must report them to that employer by the 10th of the following month.
• Your employer then withholds Social Security, Medicare, and income tax based on those reported tips, and reports them on your W-2.
• All tip income — including tips not reported to your employer — gets included on your annual tax return.

For a free reporting log, the IRS publishes Publication 1244 — Employee's Daily Record of Tips which you can download and use as a template.

"Allocated tips" — when the employer estimates for you

At larger food and beverage establishments, federal law requires employers to allocate tips among employees if the total reported tips fall below 8% of gross receipts. If you see "allocated tips" on your W-2 in box 8, those are amounts the IRS treats as your income whether or not you actually received them. That's a cue to start keeping your own daily log immediately — your records can rebut an inaccurate allocation.

Cash income from side work

If you're not a W-2 employee — say you're babysitting, doing handyman work, cleaning, or selling crafts at a market — cash you receive is typically self-employment income. The IRS expects you to:

• Track every payment you receive (date, amount, who paid you, what for).
• File a Schedule C with your annual return reporting your gross income and ordinary, necessary business expenses.
• Pay self-employment tax (Social Security + Medicare for self-employed people, currently 15.3% on the first portion of net earnings) on top of regular income tax.
• Make quarterly estimated tax payments if you expect to owe at least $1,000 for the year.

Why "they'll never know" is a bad bet

Two practical reasons unreported income tends to surface:

• Bank deposits. Large or repeated cash deposits trigger reports to the Treasury (Currency Transaction Reports for $10,000+, Suspicious Activity Reports for unusual patterns). The IRS can review these in an audit.
• Lifestyle audits. If your reported income doesn't match how you live (rent, car, vacations), the IRS has tools to estimate underreporting and assess back taxes plus penalties and interest.

A simple daily routine

You don't need accounting software for this. You need 60 seconds at the end of each shift. Write down:

1. Date
2. Hours worked
3. Cash tips received
4. Charged tips received
5. Tips paid out to others
6. Net tips for the day

At the end of the month, total it. Report to your employer, save a copy. At tax time, your annual total is sitting there, ready to plug in.
