You generally must still report taxable income even if you did not receive a Form 1099.
The reporting obligation is based on the income you actually received, not on whether the payer sent you an information return. You should use your own records to report the correct amount, such as invoices, bank deposits, payment app statements, bookkeeping records, or other payment documentation.
If the income was from self-employment or independent contractor work, you generally report it on Schedule C (Form 1040). If your net earnings from self-employment are $400 or more, you generally must also file Schedule SE (Form 1040) to calculate self-employment tax.
If the income was not self-employment income, you report it according to the type of income involved. For example, interest, dividends, unemployment compensation, taxable state tax refunds, prizes, or other taxable income are reported in different places on the return depending on the item.
If you expected a 1099 but did not receive one, you should request a copy from the payer. If the form is missing or incorrect, you still should report the correct income based on your records rather than omit it from the return.
State Law Note
State income tax reporting rules are administered at the state level and can differ from the federal rules above. The controlling authority is the applicable state revenue department or tax agency.
