Why Amazon Sellers Often Owe Taxes
1099-K Reports Gross Revenue, Not Profit
Amazon's 1099-K shows total payment volume — every sale before fees, refunds, and cost of goods. Sellers who pay taxes based on that gross number dramatically overpay. Those who don't file because they think there's nothing left after expenses often underreport. Getting the actual net profit right requires accurate COGS and expense tracking.
FBA Fees, Storage, and Ad Spend Are Often Missed
Fulfillment fees, monthly storage fees, pick-and-pack costs, Sponsored Products ad spend, referral fees, and subscription fees for Seller Central are all deductible business expenses. Sellers who don't categorize these in their bookkeeping pay tax on revenue dollars they already gave back to Amazon.
No Withholding on Any Amazon Payouts
Amazon deposits net proceeds biweekly with zero tax withheld. Sellers who reinvest every dollar back into inventory never build a cash reserve for taxes. After a growth year, the resulting SE tax plus income tax bill arrives in April with no savings set aside to cover it.
Deductions That Matter for Amazon Sellers
The point is not to get aggressive with deductions. The point is to document the real cost of earning your income so you are not paying tax on money you had to spend to do the work.
- Cost of goods sold (COGS)
- Amazon FBA fulfillment and storage fees
- Referral fees and Seller Central subscription
- Sponsored Products and advertising spend
- Shipping, prep, and packaging costs
- Software for inventory management and repricing
- Home office used for business operations
- Returns and allowances

Common Questions From Amazon Sellers
No. The 1099-K reports gross sales before any deductions. Your taxable income is net profit — gross revenue minus cost of goods sold, Amazon fees, advertising, shipping, and other business expenses. TaxWave builds your Schedule C correctly so you're only taxed on actual profit, not top-line revenue.
Inventory purchases are deductible as cost of goods sold — but only for units actually sold during the year. Unsold inventory on hand at year-end is an asset, not a current-year expense. If your inventory grew significantly, part of your purchasing cost carries into next year, which can create a tax bill despite feeling cash-poor.
Amazon's Marketplace Facilitator laws mean Amazon collects and remits state sales tax on your behalf in most states. But income tax nexus is a separate question. If you have FBA inventory warehoused in a state, you may have income tax filing obligations there. TaxWave reviews your FBA state footprint.
Filing late is much better than not filing at all. Failure-to-file penalties are steeper than failure-to-pay penalties. TaxWave prepares delinquent returns for all unfiled years, calculates the correct tax with all deductions applied, and works with the IRS to set up a resolution — whether that's a payment plan, penalty abatement, or another option.
