Schedule C for Amazon Sellers & E-commerce: Tax Guide (2026)

Amazon sellers and e-commerce business owners face unique tax complexities — especially around COGS, platform fees, and inventory accounting. Understanding how to properly report these on Schedule C can save thousands in taxes and reduce audit risk.

This guide explains how to correctly file Schedule C for Amazon FBA and e-commerce sellers, with IRS references, real examples, and common mistakes to avoid.

Income Reporting for Amazon Sellers

Schedule C Line 1 — Gross Receipts

Include:

Amazon disbursements (gross, before fees)
Shopify and Stripe payouts
eBay, Walmart, and other platform sales
Refunds handled separately (reduce gross)

Common Audit Error

Never report net Amazon deposits only. You must report gross sales and deduct fees separately. IRS can match 1099-K forms showing gross amounts.

Amazon FBA Fees Breakdown (All Deductible)

Fee Type	Schedule C Line	Notes
Referral Fees	Line 10 (Commissions)	8-15% of sale price
FBA Fulfillment Fees	Line 10 or Line 27a	Pick, pack, ship costs
Storage Fees	Line 20b (Rent)	Monthly + long-term storage
Amazon PPC Advertising	Line 8 (Advertising)	Sponsored Products, Brands, Display
Removal/Disposal Fees	Line 27a (Other)	Inventory removal costs
FBA Labeling Fees	Line 27a (Other)	Per-item prep charges

Example: Annual Amazon FBA fees totaling $32,800 are fully deductible, reducing taxable income dollar-for-dollar.

Cost of Goods Sold (COGS) — The Big Deduction

Schedule C Part III is critical for sellers with inventory.

What Goes Into COGS

Product manufacturing or wholesale cost
Packaging materials
Freight and shipping to Amazon
Customs and import duties
Prep center fees

What Does NOT Go Into COGS

Amazon selling fees (those are operating expenses)
Advertising costs
Software subscriptions
Office supplies

Inventory Accounting Methods

Choose FIFO, LIFO, or Average Cost and apply consistently. Use Amazon's inventory reports to calculate beginning and ending inventory values.

IRS Reference: IRC §280A

Bank Statement Reconciliation for Amazon Sellers

Amazon statements rarely match bank deposits line-by-line. Disbursements combine sales, refunds, and fees into single deposits, making reconciliation challenging.

A bank statement converter helps e-commerce sellers turn bank PDFs into structured Excel files for QuickBooks, making it easier to:

Reconcile Amazon disbursements with bank deposits
Categorize expenses by Schedule C line
Track supplier payments and software subscriptions
Maintain audit-ready records

Common Amazon Seller Audit Triggers

Reporting net income instead of gross (IRS has your 1099-K)
Missing or incorrect inventory adjustments
High advertising spend with low revenue
No COGS documentation
Mixing personal and business expenses
