What Are the Core Tax Write-Offs Every FBA Seller Should Know?
Quick Answer: FBA sellers deduct inventory costs, Amazon fees, shipping, software, and home office expenses. These ordinary business expenses directly reduce taxable profit in 2026.
Every Amazon business generates dozens of deductible expenses. However, many sellers leave money on the table by missing simple write-offs. The tax write-offs every FBA seller should know start with the costs you already pay to run your store. Therefore, tracking these carefully is the first step toward lower taxes. Uncle Kam helps busy e-commerce entrepreneurs capture every eligible deduction.
Most FBA sellers report income and expenses on Schedule C. As a result, understanding what qualifies matters enormously. The IRS explains ordinary and necessary business expenses in its official small business guidance. Furthermore, good records protect you if the IRS ever asks questions.
Inventory, COGS, and Amazon Fees
Your cost of goods sold (COGS) is often your largest deduction. Consequently, tracking product costs, inbound freight, and prep fees is essential. Amazon charges many fees, and nearly all of them are deductible.
- FBA fulfillment and storage fees
- Referral and selling plan fees
- Product photography and prep services
- Inbound shipping to Amazon warehouses
Additionally, inventory lost or damaged in Amazon warehouses may be deductible if not reimbursed. Therefore, reconcile your reimbursements carefully each quarter.
Home Office and Software Tools
If you run your FBA business from home, part of your rent and utilities may be deductible. However, you must use the space regularly and exclusively for business. The IRS details the rules in its home office deduction page. Moreover, the simplified method allows $5 per square foot up to 300 square feet.
Software subscriptions also add up quickly for sellers. As a result, these recurring costs create steady deductions.
- Keyword and product research tools
- Bookkeeping and inventory software
- Virtual assistant and contractor payments
Pro Tip: Pay contractors over $600 correctly and issue Form 1099-NEC. This keeps your deductions audit-proof.

Vehicle and Travel Deductions
Driving for your business generates mileage deductions. Notably, the IRS raised the 2026 business mileage rate midyear. From January 1 through June 30, the rate was 72.5 cents per mile. Beginning July 1, 2026, it rose to 76 cents per mile. Therefore, record when each trip occurred to apply the correct rate.
How Does the Permanent 20% QBI Deduction Help FBA Sellers?
Quick Answer: The 20% QBI deduction lets eligible FBA sellers deduct one-fifth of qualified business income. The OBBBA made it permanent for 2026.
The Qualified Business Income deduction is a powerful tool. Previously, this Section 199A deduction was scheduled to expire. However, the One Big Beautiful Bill Act made it permanent. As a result, FBA sellers can now plan around it with confidence. This is one of the most valuable tax write-offs every FBA seller should know in 2026.
The deduction generally equals 20% of your qualified business income. Consequently, a seller with $100,000 of QBI could deduct up to $20,000. The IRS explains eligibility in its QBI deduction overview. Furthermore, income limits and phase-outs apply to higher earners.
Who Qualifies for the QBI Deduction?
Most FBA sellers operating as sole proprietors, LLCs, or S corps can qualify. However, taxable income above certain thresholds triggers limitations. Therefore, entity choice and income planning matter. Uncle Kam’s entity structuring services help sellers optimize this deduction.
A Simple QBI Calculation
Consider an FBA seller with $120,000 in net profit. After the 20% QBI deduction, they reduce taxable income by $24,000. As a result, at a 22% marginal rate, that saves roughly $5,280. Moreover, this benefit stacks with the standard deduction of $16,100 for single filers in 2026.
Pro Tip: Combine QBI planning with retirement contributions. This lowers taxable income and can preserve your full QBI deduction.
How Can You Deduct Equipment and Retirement Contributions in 2026?
Quick Answer: Section 179 expensing and 100% bonus depreciation let you deduct equipment fully in 2026. Retirement plans add large deductions too.
Equipment purchases can produce big deductions. For 2026, the Section 179 expensing limit rose to $2.5 million. Additionally, the OBBBA made 100% bonus depreciation permanent. Therefore, FBA sellers can write off computers, cameras, and warehouse equipment immediately. The IRS covers these rules in Publication 946.
Retirement contributions are another overlooked strategy. Furthermore, they build wealth while cutting taxes. Many self-employed sellers and 1099 professionals ignore this opportunity.
Solo 401(k) and SEP IRA Options
A Solo 401(k) suits sellers with no employees. In 2026, total Solo 401(k) contributions can reach approximately $66,000. Meanwhile, a SEP IRA allows contributions up to 25% of net self-employment earnings. Consequently, high-earning sellers can shelter substantial income.
- Solo 401(k): employee plus employer contributions
- SEP IRA: simple setup, percentage-based limits
- Both reduce current-year taxable income
2026 Deduction Comparison Table
| Deduction | 2026 Limit | Best For |
|---|---|---|
| Section 179 Expensing | $2.5 million | Equipment-heavy sellers |
| Solo 401(k) | ~$66,000 | Solo owners, no staff |
| QBI Deduction | 20% of QBI | Most FBA sellers |
| Standard Deduction (Single) | $16,100 | All individual filers |
Did You Know? For 2026, the standard deduction is $16,100 for single filers and $32,200 for married couples filing jointly.
What Is the New IRS Automatic Penalty Relief for 2026?
Free Tax Write-Off FinderQuick Answer: The IRS Automatic Exemption from Penalty waives certain penalties automatically. Sellers with three years of clean compliance qualify.
In 2026, the IRS launched a major change to penalties. Specifically, it replaced First-Time Abate with the Automatic Exemption from Penalty (AEP) program. As a result, eligible taxpayers no longer need to request relief. The IRS explains penalty rules on its penalty relief page.
This shift rewards consistent filers directly. Furthermore, it applies to failure-to-file, failure-to-pay, and failure-to-deposit penalties. Therefore, staying compliant now has real dollar value. A Florida tax strategist can help you build a clean record.
Who Qualifies for Automatic Relief?
Taxpayers with a three-year history of on-time filing and payment qualify. Meanwhile, quarterly filers need 12 consecutive quarters of compliance. However, estate and gift tax returns are not eligible. Consequently, most FBA sellers can benefit by simply staying current.
How FBA Sellers Should Prepare
Preparation is straightforward but crucial. As a result, these habits protect your eligibility.
- File every return on time, even during busy seasons
- Pay quarterly estimated taxes by each deadline
- Keep organized records year-round with reliable systems
The next quarterly estimated payment is due September 15, 2026. Therefore, mark your calendar now. Uncle Kam’s bookkeeping and business solutions keep sellers on schedule.
When Do Opportunity Zones Make Sense for FBA Sellers?
Quick Answer: Opportunity Zones help FBA sellers defer and reduce capital gains when selling a brand. The OBBBA made them permanent.
Selling your FBA brand can trigger a large capital gain. However, Opportunity Zones offer a powerful planning tool. The OBBBA made Opportunity Zones a permanent, recurring regime. Additionally, the IRS issued Notice 2026-40 to govern the transition. You can review the program on the IRS Opportunity Zones page.
These strategies suit high-net-worth entrepreneurs with major gains. Nevertheless, they require careful compliance and long holding periods.
The 10-Year Benefit Explained
The 10-year benefit remains the most powerful feature. Specifically, a qualifying investment held at least 10 years can step up basis to fair market value. Under the amended rule, this occurs on the earlier of sale or 30 years after investment. Economically, this can eliminate federal tax on post-investment appreciation.
A Simple Exit Scenario
Imagine you sell your FBA brand for a $1 million gain in 2026. If you reinvest through a qualified Opportunity Fund, you defer that gain. Furthermore, appreciation inside the fund can grow tax-free after 10 years. This illustration is for education only; results vary by situation.
Pro Tip: Rural Opportunity Funds may offer a 30% basis increase after five years. Always confirm fund qualification first.
Opportunity Zones are complex and not for everyone. Therefore, work with an experienced advisor before committing capital. Uncle Kam’s proactive tax strategy team models these decisions carefully. Sellers in the Tampa area can also connect through our Amazon seller tax write-off resources for local support.
Uncle Kam in Action: The Scaling FBA Seller
Client Snapshot: Maria runs a home goods FBA brand from her Tampa home office. She sells across three product categories and uses two contractors.
Financial Profile: Maria’s Amazon store generated $780,000 in revenue in 2026. Her net profit reached roughly $210,000 after product and fulfillment costs.
The Challenge: Maria paid too much in taxes the prior year. Moreover, she missed deductions and once filed a return late. As a result, she faced penalties and a stressful tax season. She needed a structured plan for 2026.
The Uncle Kam Solution: First, we captured every deduction, including home office, software, and contractor payments. Next, we confirmed her 20% QBI deduction eligibility. Then, we opened a Solo 401(k) to shelter income. Additionally, we restructured her business as an S corp to reduce self-employment tax. Finally, we built a filing calendar to protect her Automatic Exemption from Penalty eligibility.
The Results: Maria’s combined strategies produced meaningful savings. Her retirement contribution alone reduced taxable income significantly. Furthermore, the QBI deduction and entity change cut her tax bill further.
- Tax Savings: $41,000 in the first year
- Investment: $8,500 in Uncle Kam fees
- First-Year ROI: Roughly 4.8x return
