Amazon sellers face a challenging reality in 2025: increasing FBA fees, higher shipping costs, and tightening competition have made maintaining healthy profit margins more difficult than ever.
Sellers are forced to analyze every possible way to reduce expenses without sacrificing growth. One of the most effective and often overlooked strategies is using tax-free fulfillment centers to avoid paying state sales tax on inbound inventory.
According to the 2025 Jungle Scout Seller Report, over 54% of U.S.-based Amazon sellers report margins below 20%, with many struggling to manage unexpected storage and shipping costs.
Choosing a prep center in a sales-tax-exempt state, such as Delaware, Oregon, Montana, New Hampshire, or Alaska, can instantly increase per-unit profitability by 5% to 10%. For high-volume sellers, these savings add up quickly, offering a significant competitive advantage.
Key Takeaways
- Tax-free fulfillment reduces per-unit costs by eliminating inbound sales tax, directly increasing net margins.
- Delaware, Oregon, Montana, New Hampshire, and Alaska all offer 0% sales tax, but Delaware dominates because of its logistics, infrastructure, and Amazon FBA network integration.
- Sellers using Delaware-based prep centers can save thousands of dollars per shipment, improve cash flow, and scale their catalogs faster without cutting product quality or margins.
Why Tax-Free Fulfillment Matters

U.S. state sales tax rates vary between 0% and 9.5%. Sellers who ship products into prep centers located in taxed states are forced to pay extra on every unit they process, directly eating into profits.
By contrast, choosing a prep center in a tax-exempt state ensures you skip this cost entirely.
For example:
- Using a prep center in Texas (8.25% sales tax): Importing 1,000 units of a $25 product adds $2,062.50 in sales tax.
- Using a prep center in Delaware (0% sales tax): $0 paid – an immediate savings of over $2,000.
This isn’t just a minor financial benefit. When margins are already thin, avoiding tax on inbound shipments can make the difference between profitable scaling and operating at a loss.
How Tax-Free Fulfillment Increases Amazon Profit Margins

Here’s a clear breakdown showing the difference tax-free fulfillment makes to your per-unit margins:
Factor | Without Tax-Free Fulfillment | With Tax-Free Fulfillment | Impact on Profitability |
Product Cost | $25.00 | $25.00 | No change |
Sales Tax (avg. 6%) | +$1.50 | $0.00 | Saves $1.50/unit |
Prep & Labeling Fees | $1.50 | $1.50 | Neutral |
FBA Fees | $3.80 | $3.80 | Neutral |
Net Margin per Unit | ~$7.20 | ~$8.70 | +20.8% higher margin |
Looking at the first table, the margin boost from tax-free fulfillment is significant – a difference of $1.50 per unit may not seem huge on paper, but at Amazon’s scale, it compounds quickly.
For a shipment of 10,000 units, sellers gain an extra $15,000+ without touching pricing, ad spend, or product sourcing. In highly competitive categories where average margins hover around 15–20%, adding another 5–10% in savings can be the difference between profitable scaling and stagnation.
What makes this model especially powerful is that the unit cost, FBA fees, and prep fees remain unchanged. This means sellers aren’t forced to cut corners on product quality or increase volume to maintain profitability – the gains come entirely from reducing unnecessary overhead.
Unlike discount-based strategies or price wars, tax-free fulfillment protects margins without sacrificing your competitive positioning.
Best States for Tax-Free Amazon Fulfillment
Some states have zero sales tax policies, making them the best choices for Amazon sellers seeking higher margins:
State | Sales Tax Rate | Strategic Advantages | Best Use Case |
Delaware | 0% | Top-rated prep centers, East Coast hub | FBA prep, fast regional delivery |
Oregon | 0% | Close to major West Coast ports | Import-heavy sellers |
Montana | 0% | Lower warehouse overhead | Sellers shipping regionally west |
New Hampshire | 0% | Smaller operations, strong compliance | Niche SKUs and FBM sellers |
Alaska | 0% | Regional advantages, limited options | FBM-focused fulfillment |
Logistical Advantage
Delaware is strategically located on the East Coast, close to several Amazon FBA hubs. Shipping times to major fulfillment centers in Pennsylvania, New Jersey, and Maryland are faster and cheaper, which reduces both transit costs and inventory delays.
Prep Center Ecosystem
Delaware hosts some of the most advanced Amazon prep and forwarding facilities in the U.S., providing a competitive advantage to sellers who want professional FBA-compliant processing without extra handling headaches.
Scalability for High-Volume Sellers
While Oregon and Montana also offer 0% tax rates, their warehouse density and Amazon network integrations are less developed. Delaware combines tax-free savings with infrastructure tailored to Amazon sellers, making it ideal for scaling operations efficiently.
