Amazon FBA Fees, Referral Fees & Storage Costs Tax Rules 2026: The Complete Deduction Guide
Understanding Amazon FBA fees, referral fees & storage costs tax rules 2026 is one of the most valuable things you can do as a seller right now. Every dollar you pay Amazon in FBA fulfillment fees, referral commissions, and monthly storage charges is potentially a fully deductible business expense under IRC Section 162. However, most Amazon sellers leave thousands of dollars on the table each year simply because they do not know where these fees belong on their tax return. This guide solves that problem completely for the 2026 tax year.
Key Takeaways
- For 2026, Amazon FBA fulfillment fees are fully deductible as ordinary and necessary business expenses under IRC Section 162.
- Referral fees of 8%–15% paid to Amazon are deductible as selling commissions on Schedule C or your business entity return.
- Monthly and long-term storage fees are deductible 2026 business expenses, reported under other expenses or COGS.
- Proper recordkeeping using Amazon’s Payments reports and Seller Central data is required to substantiate every deduction.
- Your entity structure in 2026 — sole proprietor, LLC, or S Corp — determines exactly where and how you report these deductions.

Are Amazon FBA Fees Tax Deductible in 2026?
Quick Answer: Yes. For the 2026 tax year, Amazon FBA fees are fully deductible as ordinary and necessary business expenses under IRS Section 162. You must use them in your trade or business to qualify.
Amazon FBA sellers in 2026 are running legitimate businesses. Therefore, they can deduct all ordinary and necessary operating costs from their taxable income. The IRS defines an ordinary expense as one that is common and accepted in your trade or business. A necessary expense is one that is helpful and appropriate for your business, even if it is not absolutely required.
Every single Amazon FBA fee you pay falls squarely within these definitions. You pay fulfillment fees to pick, pack, and ship your products. You pay referral fees as the cost of selling on the platform. You pay storage fees to keep your inventory at Amazon’s fulfillment centers. All of these are normal, accepted costs of running an e-commerce business in 2026. As a result, they all qualify as deductible expenses under IRC Section 162.
What Makes a Fee “Ordinary and Necessary” for an FBA Business?
The IRS does not require a fee to be absolutely essential — it only needs to be appropriate and helpful. For an Amazon FBA seller, every fee Amazon charges directly enables revenue generation. Without fulfillment fees, Amazon would not ship your orders. Without paying the referral fee, your listing would not stay on the platform. Therefore, these fees satisfy both the ordinary and necessary tests without question.
Furthermore, the IRS’s Guide to Business Expense Resources confirms that selling commissions, warehousing fees, and fulfillment costs are all deductible trade or business expenses. This is strong authority supporting your Amazon FBA fee deductions for 2026.
The 2026 FBA Fee Landscape: What You Are Actually Paying
Amazon charges FBA sellers several distinct types of fees in 2026. Each type has a different character for tax purposes. Understanding this distinction helps you report deductions accurately and reduces audit risk. Here is a breakdown of the primary fee categories:
- FBA Fulfillment Fees: Per-unit fees covering pick, pack, and ship. These are direct selling costs and are fully deductible in 2026.
- Referral Fees: A percentage of each sale (typically 8%–15%) that Amazon keeps as its selling commission. These are deductible as commissions or selling expenses.
- Monthly Inventory Storage Fees: Charged per cubic foot for standard and oversized items. These are deductible as storage or warehousing expenses.
- Long-Term Storage Fees (LTSF): Additional charges for inventory stored more than 365 days. These remain deductible even though they are penalty-like in nature.
- Removal and Disposal Fees: Fees Amazon charges to return or dispose of your inventory. These are deductible business expenses in 2026.
- Return Processing Fees: Charged when buyers return items for free returns. These are deductible as fulfillment-related costs.
Pro Tip: In 2026, Amazon shows all your fees in the Payments section of Seller Central. Download your monthly transaction reports to get an exact total of every fee paid during the year. This report is your best documentation for IRS purposes.
How Do Amazon Referral Fees Get Reported on Your 2026 Tax Return?
Quick Answer: For 2026, Amazon referral fees are reported as commissions or selling expenses on Schedule C (Line 10) for sole proprietors, or as a deductible expense on your entity’s tax return. They reduce your taxable profit directly.
Amazon referral fees are the platform’s selling commission. In 2026, they typically range from 8% to 15% of the sale price depending on your product category. For example, electronics referral fees are often around 8%, while jewelry and clothing can reach 15% or higher. These fees are paid to Amazon for allowing you to use its marketplace to reach buyers.
From a tax perspective, referral fees function exactly like sales commissions. They are a direct cost of generating each sale. Consequently, the IRS treats them as ordinary and necessary selling expenses. You deduct them in the year you paid them, which is the year Amazon withheld them from your disbursement — not the year you received the order. This is the cash method of accounting, which most small business sellers use in 2026.
Referral Fees by Category: 2026 Tax Impact Example
To illustrate the tax impact, consider a seller who generates $200,000 in gross revenue on Amazon in 2026. If their average referral fee rate is 12%, they pay $24,000 in referral fees to Amazon for the year. That $24,000 is fully deductible. If that seller is in a 22% effective tax bracket, the referral fee deduction alone saves approximately $5,280 in federal income taxes for 2026.
This is why working with small business owners who sell on Amazon requires careful attention to fee categorization. Many sellers report all fees together in a single line item, which can actually obscure important cost data and create confusion during an audit. Therefore, it is better practice to track each fee type separately throughout 2026.
| Amazon Fee Type | Typical 2026 Rate/Amount | Tax Treatment (2026) | Schedule C Placement |
|---|---|---|---|
| Referral Fee | 8%–15% of sale price | Fully deductible (selling commission) | Line 10 (Commissions) or Part V |
| FBA Fulfillment Fee | Varies by size/weight | Fully deductible (fulfillment cost) | Part V or COGS |
| Monthly Storage Fee | Per cubic foot, varies by season | Fully deductible (warehousing) | Part V (Other Expenses) |
| Long-Term Storage Fee | Higher rate after 365 days | Fully deductible (warehousing) | Part V (Other Expenses) |
| Removal/Disposal Fee | Per unit removed/disposed | Fully deductible (operational cost) | Part V (Other Expenses) |
| Return Processing Fee | Per returned unit | Fully deductible (fulfillment) | Part V or COGS |
What Amazon Storage Costs Are Deductible for 2026?
Quick Answer: All Amazon storage fees — monthly fees, long-term storage fees, and overage fees — are deductible in 2026 as warehousing and storage business expenses under IRC Section 162.
Amazon’s warehousing fees are a classic example of a deductible storage expense. When you send inventory to Amazon’s fulfillment centers, you are effectively renting warehouse space from Amazon. The IRS consistently allows businesses to deduct the cost of storing inventory, supplies, and goods needed to run the business. This principle applies directly to Amazon FBA storage costs in 2026.
Moreover, these fees are expenses — not capitalized costs. You do not need to depreciate them over several years. Instead, you deduct them in full during the 2026 tax year in which Amazon charged them. This immediate deduction treatment is favorable and reduces your taxable income dollar for dollar.
Monthly Storage Fees: Seasonal Considerations in 2026
Amazon charges higher storage rates during the fourth quarter (October through December) than in the first three quarters. This seasonal pricing difference does not change the deductibility of those fees. You deduct all monthly storage charges paid in 2026, regardless of whether they occurred during peak season or off-season. For cash-method taxpayers — which most individual FBA sellers are — the deduction occurs when the fee is actually charged to your account.
Sellers who want personalized guidance about tax strategists handling e-commerce returns can benefit enormously from professional planning before year-end. However, at a minimum, you should download your monthly storage fee reports from Seller Central every quarter throughout 2026. Do not wait until tax season to gather this data.
Long-Term Storage Fees: Still Deductible Despite the Higher Cost
Long-term storage fees (LTSF) are charged when your inventory sits at Amazon’s fulfillment centers for more than 365 days. Amazon assesses these fees on a monthly basis and they are typically higher per cubic foot than regular monthly storage fees. Many sellers view LTSF as a penalty — and operationally, they are. However, from a tax standpoint, they remain fully deductible business expenses in 2026.
The IRS does not distinguish between routine warehouse fees and elevated storage fees based on inventory age. Both qualify as ordinary and necessary expenses of your FBA business. Furthermore, the business pain of paying high LTSF creates a silver lining: a larger deduction that reduces your 2026 taxable income. The best strategy, of course, is to minimize LTSF through better inventory management. But when you do pay it, make certain you capture every dollar as a deduction.
Pro Tip: Use Amazon’s Inventory Health Report in Seller Central to monitor your aged inventory throughout 2026. Removing slow-moving inventory before it triggers LTSF saves you money operationally — and removal fees are also deductible.
Where Do FBA Fees Go on Schedule C or Your Business Return?
Free Tax Write-Off FinderQuick Answer: For 2026, most FBA fees go on Schedule C in Part V (Other Expenses) or Part III (Cost of Goods Sold), depending on whether you treat them as selling expenses or as direct product costs. Commissions go on Line 10.
Exactly where you place FBA fees on your 2026 return depends on two things: your business structure and your accounting method. Most solo Amazon sellers file as sole proprietors or single-member LLCs taxed as sole proprietors. They report all business income and expenses on IRS Schedule C (Form 1040). Sellers operating through S Corporations or partnerships use different forms — Form 1120-S and Form 1065, respectively.
Schedule C Placement for Each Fee Type in 2026
Here is how to correctly categorize Amazon FBA fees on Schedule C for the 2026 tax year:
- Referral Fees → Line 10 (Commissions and Fees): Amazon referral fees are selling commissions. Place them on Line 10 of Schedule C. This is the most accurate treatment and keeps your books clean.
- FBA Fulfillment Fees → Part V (Other Expenses) or Part III (COGS): Fulfillment fees can go either place. Some accountants treat them as a cost of goods sold because they are directly tied to each unit sold. Others place them in Part V. Either method is acceptable — just stay consistent year to year.
- Monthly Storage Fees → Part V (Other Expenses): Label this line item “Amazon Storage Fees” or “FBA Storage Costs” for clarity. Consistent labeling reduces the chance of an IRS inquiry.
- Long-Term Storage Fees → Part V (Other Expenses): You can list these separately from standard monthly storage fees or combine them. Separate listing is recommended if LTSF is material.
- Removal/Disposal Fees → Part V (Other Expenses): These operational fees go in other expenses, labeled clearly.
Working with a qualified professional who understands tax strategy for e-commerce businesses ensures you make the right classification decisions from the start. The difference between reporting fees in COGS versus operating expenses can affect your gross profit margin on the tax return, which sometimes matters for loan applications and lender reviews.
Gross Revenue vs. Net Revenue: How Amazon Deposits Work
Amazon does not pay you full gross revenue. Instead, it deducts all fees before depositing funds into your bank account. This creates a common error: many sellers only report the net amount deposited as income and fail to gross up their revenue and deductions properly. For 2026, the correct approach is to report your gross sales as income and then deduct all Amazon fees separately as expenses. This way, your Schedule C shows the full picture of your business activity. Reporting only net deposits understates both your income and your expenses.
Pro Tip: Your Amazon 1099-K for 2026 will show gross sales processed through Amazon, not the net deposit amount. Always reconcile your 1099-K against your Seller Central transaction reports to ensure your income figure is accurate before deducting fees.
What Records Do You Need to Deduct Amazon FBA Fees in 2026?
Quick Answer: For 2026, you need your Amazon transaction reports, monthly statements, and the annual settlement summary from Seller Central. These documents substantiate every deduction in an audit.
The IRS requires you to have documentation to support every deduction you claim. For Amazon FBA sellers in 2026, the good news is that Amazon provides detailed transaction data through Seller Central. You do not need paper receipts — digital records are fully acceptable. However, you do need to maintain those records for at least three years from the date you file your 2026 return (or three years from the due date, whichever is later).
Essential Amazon Reports for Your 2026 Tax File
Download and save the following reports from Amazon Seller Central for your 2026 tax records:
- Transaction Summary Report: Shows all fees deducted per transaction, including referral fees and FBA fees, throughout 2026.
- Monthly Payments Report: A complete monthly breakdown of income and all deducted fees. Download one for each month of 2026.
- FBA Storage Fees Report: Details monthly and long-term storage charges by month and ASIN for 2026.
- FBA Removal Fee Report: Documents all removal and disposal fee transactions in 2026.
- Annual Settlement Report (1099-K): Amazon issues this for sellers who exceed the reporting threshold. It shows your gross sales, which you will need to reconcile with your fee deductions.
In addition to Amazon reports, many sellers use accounting software like QuickBooks or a spreadsheet to categorize and total their 2026 Amazon fees by type. This extra step makes tax preparation faster and provides organized backup documentation. If you face an IRS audit, having neatly organized reports — not just raw transaction files — demonstrates careful bookkeeping and supports your deductions credibly.
Inventory and COGS Documentation for 2026
Beyond Amazon fees, you also need to document your 2026 inventory costs. Your Cost of Goods Sold (COGS) is a separate deduction from your FBA fees. COGS represents what you actually paid to purchase or manufacture the products you sold. You calculate COGS using this formula for the 2026 tax year:
COGS = Beginning Inventory + Purchases During 2026 − Ending Inventory
Keep all purchase invoices, supplier receipts, import documents, and shipping costs related to acquiring inventory in 2026. These support your COGS deduction on Schedule C Part III. Note that COGS and FBA fees are separate deductions — one does not offset the other. Both reduce your net profit and your 2026 tax bill.
Use our Small Business Tax Calculator to model how your FBA fee deductions and COGS interact to reduce your 2026 tax liability. This tool helps you project your tax bill before you file.
How Does Your Entity Structure Affect FBA Tax Deductions in 2026?
Quick Answer: Your entity structure affects where you report FBA deductions and your overall self-employment tax exposure in 2026. Sole proprietors, S Corps, and LLCs each handle FBA expenses differently on their returns.
For 2026, entity structure is one of the most impactful decisions an Amazon FBA seller can make. The deductibility rules for FBA fees, referral fees, and storage costs are the same across all structures — all qualify under IRC Section 162. However, the structure determines how much self-employment tax you pay on top of income taxes, which can represent a significant savings opportunity.
Sole Proprietor / Single-Member LLC (Default) in 2026
Most first-time and part-time Amazon FBA sellers operate as sole proprietors in 2026. They report all income and expenses on Schedule C, attached to their personal Form 1040. All FBA fees reduce net profit on Schedule C. That net profit is then subject to both income tax and self-employment tax. For 2026, the self-employment tax rate is 15.3% on net self-employment income up to the Social Security wage base. This rate covers both Social Security (12.4%) and Medicare (2.9%). Therefore, every deductible FBA fee reduces not just income tax but also self-employment tax — effectively making each deduction worth more.
S Corporation Election for High-Revenue FBA Sellers in 2026
If your Amazon FBA net profit exceeds approximately $50,000 to $80,000 per year, an S Corporation election may significantly reduce your overall 2026 tax bill. Under an S Corp structure, you pay yourself a reasonable salary — which is subject to payroll taxes — and take the remaining profit as a distribution, which is not subject to self-employment tax. This approach can save thousands of dollars annually on top of your standard FBA fee deductions.
An S Corp still deducts all FBA fees, referral fees, and storage costs as business expenses. However, those deductions now flow through to you as a shareholder on Schedule K-1, rather than directly on Schedule C. The net effect is a lower tax bill, because you are eliminating the self-employment tax on the distribution portion of your income.
Explore your options with professional entity structuring guidance before you make any structure changes in 2026. The deadline to elect S Corp status for 2026 may have passed for most sellers, but planning now for a future year is smart. A qualified professional can model the exact savings based on your revenue and expense figures.
| Entity Type | Typical Return Form | FBA Fees Reported On | Self-Employment Tax on Net Profit? |
|---|---|---|---|
| Sole Proprietor | Form 1040 + Schedule C | Schedule C Part V or Part III | Yes — 15.3% on net profit |
| Single-Member LLC (default) | Form 1040 + Schedule C | Schedule C Part V or Part III | Yes — 15.3% on net profit |
| S Corporation | Form 1120-S + Schedule K-1 | Form 1120-S as business deduction | Only on salary, not distributions |
| Partnership / Multi-Member LLC | Form 1065 + Schedule K-1 | Form 1065 as partnership deduction | Generally yes, per partner |

Uncle Kam in Action: FBA Seller Cuts Tax Bill by $18,400
Client Snapshot: Marcus is a 34-year-old full-time Amazon FBA seller who primarily sells in the health, household, and grocery categories. He operates as a sole proprietor and has been selling on Amazon for four years.
Financial Profile: Marcus generated $320,000 in gross Amazon sales revenue. He paid $48,000 in Amazon referral fees, $22,000 in FBA fulfillment fees, $9,600 in monthly storage fees, and $4,800 in long-term storage fees. His total product cost (COGS) for the year was $178,000.
The Challenge: Before coming to Uncle Kam, Marcus had been reporting only his net Amazon disbursements as income and ignoring many of his fees as deductions. He was missing his referral fees entirely — treating them as simply “money Amazon didn’t pay me” rather than as deductible commissions. He was also not categorizing his storage fees separately, which meant they were not showing up on his Schedule C at all. As a result, Marcus was significantly overpaying his taxes every year.
The Uncle Kam Solution: Uncle Kam’s team corrected Marcus’s approach. They grossed up his income to reflect the full $320,000 in gross sales. They then deducted $48,000 in referral fees on Schedule C Line 10, $22,000 in FBA fulfillment fees in Part V, $9,600 in monthly storage fees in Part V, and $4,800 in LTSF in Part V. This totaled $84,400 in previously unclaimed Amazon fee deductions. Additionally, Uncle Kam helped Marcus properly document his $178,000 COGS and identified an additional $12,000 in home office, software, and advertising deductions Marcus had overlooked.
- Tax Savings: $18,400 in combined federal income and self-employment tax saved.
- Investment: Marcus paid $3,200 in advisory fees.
- First-Year ROI: 475% — $18,400 in savings on a $3,200 investment.
Marcus also engaged Uncle Kam to model an S Corp election for a future year, with potential additional self-employment tax savings as his revenue continues to grow. See more results like Marcus’s on our client results page.
