## 🧾 Bonus #2: 2026 US E-Commerce Tax & 1099-K Survival Checklist

> **Disclaimer:** *This template is for bookkeeping organization and educational purposes only. Always consult a licensed US CPA or Enrolled Agent for official tax filing.*

* **Rule #1: Don't Pay Tax on Your Gross 1099-K Number!**
  * Platforms report **Gross Unadjusted Sales** on Form 1099-K (including refunded orders, platform referral fees, and shipping labels deducted from your payout).
  * In Tab #2 (`02_US_Schedule_C_Tax_And_Bookkeeping_2026`), always enter your **Gross 1099-K amount** in Column C/D, and subtract **Refunds (Col E)**, **Platform Fees (Col H/I)**, **Shipping Labels (Col G)**, and **Creator Commissions (Col J)** so you are only taxed on your true Net Profit.
* **Rule #2: Marketplace Facilitator Sales Tax (US States)**
  * **TikTok Shop US, Etsy, Amazon, Walmart, eBay, and Whatnot** are *Marketplace Facilitators*—they automatically collect and remit state sales tax across all US states on your behalf.
  * **Shopify DTC:** You must monitor economic nexus thresholds (typically `$100,000` in sales or `200` transactions in a state) inside *Shopify Tax*.
* **Rule #3: Deduct Unreturned Creator Samples!**
  * Every product sample you ship to a TikTok/Instagram affiliate is 100% tax-deductible (log the manufacturing COGS + outbound USPS postage under Promotional/Sample Expenses in Tab #2 and Tab #3).
