Record-Keeping for Affiliate Marketers

The records that substantiate your taxes, prove your disclosures, and document consent — and simple systems to keep them consistently.

Good record-keeping is where legal, tax, and business compliance meet. It substantiates your tax deductions, proves your disclosure practices if a regulator or program ever asks, and gives you the operational data to run the business well. None of it is difficult; it just has to be consistent.

What to keep

• Income records — commission statements from every network and program, plus any 1099s received, reconciled against your own totals.
• Expense records — receipts and invoices for hosting, domains, tools, advertising, and other business costs.
• Program agreements — a copy of each program’s terms as they were when you joined, since they change over time.
• Disclosure evidence — a record of your standard disclosure language and, where practical, archived versions of pages and posts showing disclosures in place.
• Consent records — logs from your cookie consent platform demonstrating how and when consent was obtained.

How long to keep it

Retention periods vary by jurisdiction and record type. As a general matter, keep tax records for several years after filing (US guidance commonly cites at least three years, longer in some situations), and keep consent and disclosure evidence for as long as the related activity and its limitation periods run. When in doubt, keep longer rather than shorter, and confirm specifics with a qualified professional.

Practical systems

1. Separate business banking so income and expenses are cleanly traceable.
2. A simple bookkeeping tool or spreadsheet updated monthly, not annually.
3. A folder structure (or accounting software) for receipts and statements.
4. A periodic export of consent logs and, if feasible, page archives.
5. A recurring reminder to reconcile commissions and set aside estimated tax.
