Marketplace and payment-processing fees
Keep Etsy statements showing listing, transaction, advertising and payment-processing charges.
An Etsy seller’s taxable business profit can be very different from marketplace sales. Platform fees, shipping, materials, advertising and inventory-related costs can materially change profit, so a flat percentage of gross sales is often a poor substitute for bookkeeping.

Online sellers should reconcile marketplace reports with their own books because deposits can be lower than gross customer payments after fees, refunds or other charges. Inventory and cost-of-goods-sold issues can also be more complex than ordinary operating expenses, so the simple calculator is a planning tool rather than inventory accounting.
The IRS says gig-economy income is taxable even when the work is part-time, temporary or not reported on an information return. Use the forms you receive to reconcile your records, but base the tax estimate on the complete business activity required by the tax rules.
These are categories to review, not automatic deductions. A cost still needs to meet the tax rules and be supported by records.

Postage, boxes, mailers, labels and packing supplies used for customer orders may be business costs.
Track materials used to make products separately from general operating supplies.
Business advertising and product-listing costs may be relevant when ordinary and necessary.
A qualifying business-use-of-home deduction has specific rules; use the dedicated home-office calculator for planning.
Self-employed 1099 workers may need estimated payments during the year. The amount to save and the amount to send this quarter are separate questions. If you also have a W-2 job, payroll withholding can affect how much tax remains unfunded.
The IRS states that gig-economy income is taxable even if no Form 1099-K, 1099-NEC or other information return is issued. Keep your own income and expense records and reconcile them to any forms you receive.
The mini calculator uses the same documented 2026 planning engine as Analyze My Income's main 1099 tools. It starts with gross 1099 income, subtracts the business expenses you enter, estimates self-employment tax, federal income tax and the selected state income-tax path, then expresses modeled taxes as a share of gross 1099 revenue. The full calculator can also account for W-2 wages, withholding, health insurance and payments already made.
