To report income without a 1099, you must diligently track all earnings and report them as self-employment income on Schedule C (Form 1040), detailing income and expenses, then use Schedule SE for self-employment taxes if net earnings are $400+, and potentially make estimated quarterly payments using Form 1040-ES to avoid penalties, treating all cash/gig income as taxable.
Freelancers and independent contractors often get paid in cash, but they still need to report this income to the IRS, even if they don't receive a 1099 form. Cash payments count as self-employment income and must be included on Schedule C when filing taxes.
If you cannot get a copy of your W-2 or 1099, you can still file taxes by filling out Form 4852, “Substitute for Form W-2, Wage and Tax Statement.” This form asks for information about your wages and taxes that were withheld.
If the missing 1099 is for self-employment earnings, and your net self-employment income is at least $400 for the year, you should file a Schedule SE with your amended return. The IRS uses this form to calculate your self-employment tax. This includes Social Security and Medicare taxes.
Depending on your side hustle, you'll likely need to fill out a Schedule C (Profit or Loss from Business) to report earnings or losses from your side gig. Include the income from Forms 1099-NEC and 1099-K with all other income for the side hustle on your Schedule C.

The biggest tax mistakes people make include filing late, math errors, incorrect personal info (like Social Security numbers), forgetting deductions/credits (like EITC), misreporting income, not signing forms, and making errors with bank details for direct deposit, all leading to delays, penalties, or missed savings, with using tax software or professionals helping avoid these common pitfalls.
Instead, you must report your self-employment income on Schedule C (Form 1040) to report income or (loss) from any business you operated or profession you practiced as a sole proprietor in which you engaged for profit.
For services performed in 2025 and prior, you get a 1099-NEC (or MISC) if you earn $600 or more from one business; starting in tax year 2026, that threshold increases to $2,000 for Form 1099-NEC and Form 1099-MISC, adjusted for inflation in later years, but you must always report all self-employment income, regardless of whether you receive a form.
In the most serious cases of IRS audit unreported income, the government may pursue criminal charges. This is rare, but when it happens, the conviction rate is high. Criminal charges require proof of “willful” violation of a known legal duty.
The IRS does not check every tax return. It does not check the majority of them, but the IRS implements methods that track certain factors that would result in a further examination or audit by them.
Generally, the IRS can include returns filed within the last three years in an audit. If we identify a substantial error, we may add additional years. We usually don't go back more than the last six years. The IRS tries to audit tax returns as soon as possible after they are filed.
If you're unable to get a W-2 or 1099, you can file Form 4852 as a substitute. Use your records to estimate your income and taxes, and attach the form to your return. If your employer or payer filed the missing form with the IRS, you can request a Wage and Income Transcript to get the information directly from the IRS.
If you are an employee, you report your cash payments for services on Form 1040, line 7 as wages. The IRS requires all employers to send a Form W-2 to every employee. However, because you are paid in cash, it is possible that your employer will not issue you a Form W-2.
There are many alternatives to pay stubs, including tax returns, bank statements, employer income letters, 1099s, Social Security statements, court-ordered payments, unemployment benefit letters, annuity statements, interest and dividend income statements, and bonus/incentive payout records.

A person must file Form 8300 if they receive cash of more than $10,000 from the same payer or agent: In one lump sum. In two or more related payments within 24 hours. For example, a 24-hour period is 11 a.m. Tuesday to 11 a.m. Wednesday.
The One Big Beautiful Bill Act of 2025 repeals the $600 threshold set by the American Rescue Plan Act of 2021, returning the Form 1099-K reporting threshold to $20,000 and 200 transactions.
