No 1099 received? Reconstruct your 2026 business income

Waiting for a Form 1099 is not a bookkeeping system. If a customer or payment platform does not send one, a Houston small-business owner still needs to determine and report the business income received during 2026.

The IRS says gig-economy income must be reported even when it is not shown on Form 1099-K, Form 1099-NEC, Form 1099-MISC or another income statement. The 2025 Schedule C instructions likewise tell sole proprietors to report income from all business sources. The IRS has not yet published 2026 Schedule C instructions, so this guide applies that existing rule to records kept during 2026 and should be checked again when the 2026 form instructions are released.

Start with your books, not the missing form

A 1099 is an information return prepared by someone else. It can help confirm part of your income, but it does not replace your sales records. Build the annual total from the records created when you invoiced a customer, received a payment and deposited the money.

Collect records for every way customers paid you:

• invoices, sales reports and receipt books;
• business checking and savings statements;
• card-processor and payment-app transaction exports;
• copies of checks and mobile-deposit records;
• cash logs and deposit slips;
• marketplace settlement reports;
• digital-asset payment records; and
• bookkeeping entries and year-end accounts-receivable detail.

Keep personal transfers, owner contributions, loans, refunds and reimbursements visible during the review. A bank deposit is evidence of money moving, but it is not automatically business income.

Reconstruct one payment channel at a time

Create a worksheet with the transaction date, customer, invoice number, gross amount, payment channel, fees, refunds and bank deposit. Then reconcile each channel separately before combining the totals.

For card processors and payment apps, start with gross customer payments. Processor fees and refunds may cause the bank deposit to be lower than the sales amount. For checks, connect each deposited check to an invoice or receipt. For cash, compare the daily cash log with deposit records and cash used for documented business expenses.

The result should explain both sides of the books: the gross receipts earned and the cash that reached the bank after fees, refunds or other adjustments.

Use 1099 forms as a cross-check

When Forms 1099 arrive, compare each one with the reconstruction. Do not add the form amount automatically; the transaction may already be included in the books.

Check:

1. whether the payer and taxpayer information belong to your business;
2. which customers and payment dates the form covers;
3. whether the amount is gross or net of fees and refunds;
4. whether the same payment appears on another form; and
5. whether the form includes a personal transfer or other incorrect amount.

If a form is wrong, contact the issuer and keep a written record of the correction request. Continue preparing the reconciliation from reliable source records rather than deleting a known transaction or adding a duplicate to force a match.

Investigate differences before filing

A difference does not prove that income is missing. Timing, outstanding invoices, transfers between accounts, refunded sales and processor fees can all create gaps. Work through the difference by customer and payment channel.

When records are incomplete, request statements or transaction exports from the bank, processor or marketplace. Ask major customers for payment histories. Document the method used to reconstruct the total, the records reviewed and any unresolved items. Do not estimate a number simply to finish the return.

Keep a clean 2026 income package

Save the final customer ledger, channel reconciliations, bank statements, processor reports, invoices and correction correspondence together. The IRS advises businesses to retain supporting documents that show the amounts and sources of gross receipts and support entries in the books and tax return.
