مُقدِّر مدفوعات وضريبة 1099-K

If you sell on Shopify, Etsy, Amazon, or get paid through PayPal, Stripe, or other processors, you may receive Form 1099-K reporting payment card and third-party network transactions. Box 1a shows gross payments—not your take-home profit. Planning tax from the gross figure without subtracting fees and expenses is a common reason sellers overestimate April liability—or under-save for quarterly estimates.

Start with 1099-K Box 1a gross payments, subtract card processing fees and platform deductions, then subtract other ordinary business expenses. Apply self-employment tax to roughly 92.35% of net profit at the combined Social Security and Medicare rates (about 15.3%, subject to the wage base and Additional Medicare Tax). Half of SE tax is typically deductible when estimating federal income tax; progressive brackets and your state’s approximate effective rate finish a practical annual sketch.

Because marketplace and processor payouts rarely withhold income tax the way a W-2 employer would, many sellers set aside money each quarter. Dividing remaining annual tax by four is a simple habit; confirm current 1099-K issuance thresholds and safe-harbor rules for your situation. If you also receive Form 1099-NEC for contractor work, pair this tool with the 1099-NEC estimator and the general 1099 Freelance Tax Estimator.
