Income You MUST Report in 2026 — W-2, 1099-K, Gig Work, Crypto, Rent, Interest & Everything In Between
The fastest way to trigger an IRS notice is simple: leaving income off your return.
And in 2026, reporting rules are stricter than ever — especially for 1099-K, gig work, crypto, rental income, bank interest, and “small side money” taxpayers often overlook.
This guide breaks down every income category the IRS expects you to report, in plain English, so you can file confidently and avoid penalties.
1) W-2 Income — Still the Core of Most Returns
Your employer must send you a W-2 showing wages, taxes withheld, and Social Security/Medicare contributions.
The IRS receives a copy too — which means your W-2 must match exactly.
- Report wages exactly as printed
- Check for incorrect Social Security or Medicare withholding
- If you had multiple jobs, you will receive multiple W-2s
A taxpayer with 3 part-time jobs must report all three W-2s.
The IRS auto-matches them. If one is left out, a notice will be issued.
2) 1099-K — The Most Confusing Form in America (2026)
For 2026 filing, the IRS continues using the updated 1099-K threshold:
$2,500 or more in payments for goods or services.
✔ You receive a 1099-K if:
- You sold items online for profit
- You run a small business using Stripe, PayPal, Venmo Business
- You receive payments for services (tutoring, design, coaching)
✔ You do NOT receive a 1099-K if:
- You sold personal items at a loss
- You sent or received personal reimbursements
- You used Zelle (currently exempt)
A 1099-K almost always means you must file Schedule C.
You sell your used TV for $200 (you originally paid $900).
No tax. No 1099-K. No income — because it’s a loss on personal property.
3) Gig, Freelance & Side Hustle Income (Schedule C Required)
Whether or not you receive a 1099-NEC or 1099-K, all gig or freelance income is taxable.
- DoorDash, Uber, Lyft, Instacart
- Tutoring, babysitting, coaching
- Online freelancing (Upwork, Fiverr)
- Home-based services (cleaning, crafting)
You must report:
- Gross income
- Business expenses
- Self-employment tax (15.3%)
A rideshare driver earning $9,800 must report it, even if they only received a 1099-K and not a 1099-NEC.
Mileage and business expenses reduce taxable income.
4) Crypto, NFTs & Digital Assets — Mandatory Reporting
The IRS now aggressively tracks cryptocurrency.
- Crypto trading = capital gain/loss
- Crypto earned = ordinary income
- NFT purchases/sales = investment activity
- Exchange-to-exchange transfers must be documented
Most taxpayers must file:
- Form 8949 (detailed trades)
- Schedule D (summary)
Swapping Bitcoin for Ethereum is a taxable event
— even if you don’t convert to cash.
5) Rental Income & Depreciation
Rental property owners must report:
- Rents received
- Security deposits kept
- Cleaning fees or pet fees
- Depreciation (required, not optional)
- Repairs, mortgage interest, insurance
If you skip depreciation, the IRS will still recapture it when you sell.
A taxpayer who never reported depreciation for 10 years
will still owe depreciation recapture tax at sale —
even though they didn’t claim it.
6) Bank Interest, Dividends & Investment Income
The IRS receives automatic reports from banks and brokers:
- Bank interest (1099-INT)
- Dividends (1099-DIV)
- Stock sales (1099-B)
- Mutual funds & ETFs
Even $2 of bank interest must be reported.
If you forget, the IRS will send an automated CP2000 notice.
7) Other Taxable Income Most People Forget
- Unemployment compensation
- Alimony (post-2018 rules apply)
- Prizes & awards
- Jury duty pay
- Debt cancellation (Form 1099-C)
- HSA distributions not used for medical expenses
- Gambling winnings (even without a W-2G)
If income is taxable, you must report it — even when no form is issued.
