Tariffs and Sales Tax in 2026: The Double Tax Trap Resellers Don't See Coming
TL;DR: New tariffs in 2026 don't just raise your product costs - they inflate the amount you pay in sales tax too. Tariffs get baked into the price. Sales tax is calculated on that tariff-inclusive price. You pay the tariff, then pay tax on the tariff. A resale certificate eliminates the sales tax layer when buying inventory, which is one of the few tools resellers have to fight back.

What Happened: The 2026 Tariff Timeline
The tariff landscape shifted dramatically in early 2026. Here is the sequence of events:
| Date | Event | Impact |
|---|---|---|
| Pre-2026 | IEEPA tariffs in effect on China (up to 60%), others | Broad import duties across many product categories |
| Feb 20, 2026 | Supreme Court strikes down IEEPA tariffs (6-3 ruling) | Court rules IEEPA does not authorize tariffs - only financial sanctions |
| Feb 24, 2026 | Trump issues new Section 122 tariffs | 10% global tariff on all imports, quickly raised to 15% |
| Feb 24, 2026 | Section 122 tariffs take effect | 15% is the statutory maximum under Section 122 |
| July 24, 2026 | Section 122 tariffs expire | 150-day statutory limit runs out |
| Ongoing | De minimis $800 exemption eliminated | No more duty-free small shipments from overseas |
What Section 122 Means for You
Section 122 of the Trade Act gives the president authority to impose tariffs up to 15% for 150 days without Congressional approval. That is exactly what happened. The 15% rate is a hard ceiling - it cannot go higher under this authority.
The practical result: every imported product you buy just got 15% more expensive at the border. That includes goods from every country, not just China.
The De Minimis Change
Previously, shipments valued under $800 entered the US duty-free. That exemption is gone. If you source inventory from overseas suppliers who ship directly - Alibaba orders, AliExpress, small wholesale lots - every single shipment now carries tariff costs regardless of value.
The Double Tax Trap Explained
Here is the part most resellers miss entirely.
How It Works
Tariffs are paid at import. They become part of the product's landed cost. When that product gets sold at wholesale or retail, sales tax is calculated on the full price - including the tariff amount.
You are paying tax on a tax.
The Math
Let's say you import a product with a base cost of $100.
Without tariffs:
| Line Item | Amount |
|---|---|
| Product cost | $100.00 |
| Tariff (0%) | $0.00 |
| Landed cost | $100.00 |
| Sales tax (8%) | $8.00 |
| Total out of pocket | $108.00 |
With 15% tariff:
| Line Item | Amount |
|---|---|
| Product cost | $100.00 |
| Tariff (15%) | $15.00 |
| Landed cost | $115.00 |
| Sales tax (8%) | $9.20 |
| Total out of pocket | $124.20 |
The tariff added $15 to your cost. But it also added $1.20 to your sales tax. Your total increase is $16.20 - not $15. That extra $1.20 is the double tax trap.
At Scale, It Adds Up Fast
| Annual Import Spend | Tariff Cost (15%) | Extra Sales Tax on Tariff | Total Double Tax Hit |
|---|---|---|---|
| $50,000 | $7,500 | $600 | $8,100 |
| $100,000 | $15,000 | $1,200 | $16,200 |
| $250,000 | $37,500 | $3,000 | $40,500 |
| $500,000 | $75,000 | $6,000 | $81,000 |
| $1,000,000 | $150,000 | $12,000 | $162,000 |
Assumes 8% average sales tax rate. Your state rate may vary.
That "extra sales tax on tariff" column? That is money you are paying for no reason if you buy without a resale certificate.
The Household Impact
According to the Tax Policy Center, the average American household faces roughly $1,230 per year in additional costs from the current tariff structure. For resellers buying inventory in volume, the impact is many times higher.
Stop paying sales tax on your inventory purchases. A resale certificate eliminates the sales tax layer entirely - including the tax-on-tariff portion.

IEEPA Tariff Refunds: Can You Get Money Back?
If you paid tariffs under the old IEEPA authority before the Supreme Court struck them down on February 20, 2026, you may be entitled to a refund.
What We Know
The Supreme Court's 6-3 ruling was clear: the International Emergency Economic Powers Act does not give the president authority to impose tariffs. It authorizes financial sanctions - blocking assets, restricting transactions - not import duties. Every tariff collected under IEEPA was collected without proper legal authority.
The Refund Process
U.S. Customs and Border Protection (CBP) is building an automated refund system. Here is what importers need to know:
| Detail | Information |
|---|---|
| Timeline | Automated system expected approximately 45 days from March 6, 2026 |
| Who qualifies | Importers who paid IEEPA-based tariffs |
| Registration required | Must register for CBP's ACH (Automated Clearing House) program |
| Documents needed | Entry summaries, proof of tariff payment, import records |
Steps to Take Now
- Gather your import records - Pull every entry summary where you paid IEEPA tariffs
- Register for CBP's ACH program - Search CBP.gov for IEEPA refund registration details
- Calculate your refund amount - Add up all IEEPA tariffs paid
- Work with your customs broker - If you use one, they should be on top of this
- Keep documentation organized - You will need proof of payment for every claim
A Warning
The refund only covers tariffs paid under IEEPA authority. The new Section 122 tariffs are a separate legal basis. You will not get refunds on Section 122 tariffs - those are valid (up to the 15% cap, for 150 days).
How States Treat Tariffs for Sales Tax Purposes
This is where it gets complicated. Not every state handles tariffs the same way when calculating sales tax.
The General Rule
In most states, sales tax is calculated on the total amount paid by the buyer, which includes any tariff costs baked into the price. If your supplier raised prices by 15% to cover tariffs, your sales tax is calculated on that higher price. Period.
The Surcharge Question
Some suppliers are adding a separate "tariff surcharge" line item to invoices instead of raising the base price. The question: is that separate surcharge subject to sales tax?
The answer depends on the state:
| State Approach | How It Works |
|---|---|
| Surcharge is part of the sale price | Most states take this position - if it is a condition of the sale, it is taxable |
| Surcharge may be exempt | A few states may treat separately stated government-imposed charges differently |
| Unclear guidance | Many states have not issued specific guidance on tariff surcharges yet |
Streamlined Sales Tax Guidance
The Streamlined Sales Tax Governing Board - the organization that coordinates sales tax rules across member states - has issued guidance on how tariffs should be treated for sales tax purposes. If you operate in Streamlined member states, check their current interpretive guidance for specifics.
The Bottom Line on State Treatment
Unless your state has issued specific guidance saying otherwise, assume that tariff costs included in the purchase price are subject to sales tax. This is the safe position and the one most states take.
How Resale Certificates Protect You
A resale certificate does not exempt you from tariffs. Nothing does - tariffs are federal import duties paid at the border. But a resale certificate does eliminate the sales tax portion of the equation.
One Layer of Defense
Here is how the numbers change when you buy inventory with a resale certificate:
Without resale certificate (paying both tariff and sales tax):
| Cost Component | Amount |
|---|---|
| Product cost | $100.00 |
| Tariff (15%) | $15.00 |
| Sales tax (8% on $115) | $9.20 |
| Total | $124.20 |
With resale certificate (paying tariff only, no sales tax):
| Cost Component | Amount |
|---|---|
| Product cost | $100.00 |
| Tariff (15%) | $15.00 |
| Sales tax | $0.00 |
| Total | $115.00 |
Savings: $9.20 per $100 of product cost. That is the full sales tax amount - including the tax that would have been charged on top of the tariff.
Why This Matters More Now Than Ever
Before the 2026 tariffs, the sales tax you avoided with a resale certificate was calculated on the product's base cost. Now that tariffs inflate that base cost by 15%, the sales tax you avoid is calculated on a higher number. Your resale certificate saves you more money than it did six months ago.
| Scenario | Sales Tax Avoided per $100 Product |
|---|---|
| Pre-tariff (8% on $100) | $8.00 |
| Post-tariff (8% on $115) | $9.20 |
| Additional savings from having certificate | $1.20 more per $100 |
What a Resale Certificate Does NOT Do
To be clear:
- Does NOT exempt you from tariffs - Tariffs are federal import duties, not state sales tax
- Does NOT apply to personal purchases - Only for inventory you intend to resell
- Does NOT eliminate the tariff cost - Your supplier still passes tariff costs through to you
- DOES eliminate sales tax on inventory - Including the inflated amount caused by tariffs
In a world of 15% tariffs, eliminating sales tax on inventory is not optional - it is essential.

5 Things Resellers Should Do Right Now
1. Get a Resale Certificate If You Don't Have One
This is step one. Every dollar of inventory you buy without a resale certificate costs you 6-10% more than it should in sales tax. With tariffs inflating your costs, you cannot afford to leave this money on the table.
Check your state's requirements -->
2. Audit Your Supply Chain for Tariff Exposure
Map out where your products come from:
- Which suppliers import goods?
- Which products carry the 15% tariff?
- Have your suppliers raised prices? By how much?
- Are there domestic alternatives that avoid tariffs?
3. Check If You Qualify for IEEPA Refunds
If you imported goods directly and paid IEEPA tariffs before February 20, 2026, start the refund process now. Do not wait for the automated system - gather your documents and register for CBP's ACH program today.
4. Review Your Pricing
Tariffs raise your costs. You need to decide:
| Strategy | Risk |
|---|---|
| Absorb the cost | Margins shrink, may not be sustainable |
| Raise prices | May lose customers to competitors |
| Split the difference | Moderate impact on both margins and volume |
| Find cheaper sources | Takes time, may sacrifice quality |
Most resellers will need some combination of price increases and cost reduction.
5. Plan for July 24, 2026
Section 122 tariffs expire after 150 days. But that does not mean tariffs go away. Congress could pass new tariff legislation, or the administration could find another legal authority. Plan for multiple scenarios:
- Best case: Tariffs drop or expire, your costs decrease
- Likely case: Some form of tariffs continues at a lower rate
- Worst case: New tariffs at higher rates under different authority
Frequently Asked Questions
"Do I pay tariffs AND sales tax on the same product?"
Yes. Tariffs are a federal import duty. Sales tax is a state consumption tax. They are two separate systems. The tariff becomes part of the product cost, and sales tax is calculated on that tariff-inclusive cost. This is the double tax trap.
"Can my resale certificate exempt me from tariffs?"
No. A resale certificate only exempts you from state sales tax on inventory purchases. Tariffs are federal and apply regardless of your resale certificate status. However, the certificate does eliminate the sales tax layer - which is now calculated on a higher, tariff-inflated price.
"My supplier added a 'tariff surcharge' line item. Is that taxable?"
In most states, yes. If the surcharge is a required part of the purchase, it is generally included in the taxable amount. Some states may treat separately stated government-imposed charges differently, but do not assume it is exempt without checking your specific state's guidance.
"What happens after July 24 when Section 122 expires?"
The 15% tariffs under Section 122 authority expire. What replaces them is uncertain. Congress may pass new tariff legislation, or the administration may pursue tariffs under a different legal authority. The Supreme Court only ruled that IEEPA cannot be used for tariffs - it did not prohibit tariffs generally.
"Does the de minimis elimination affect me if I buy from US wholesalers?"
Directly, no. The de minimis exemption applied to imports. If you buy from US-based wholesalers, they already paid any applicable duties. However, your wholesaler's costs went up because of tariffs, and they are passing those costs through to you in higher wholesale prices.
"Should I stockpile inventory before tariffs go higher?"
That depends on your cash flow, storage capacity, and risk tolerance. Tariffs could decrease after July 24 just as easily as they could increase. Tying up cash in inventory carries its own risks. If you do stockpile, focus on fast-moving items with stable demand.
"How do I know if my products are affected by tariffs?"
Nearly all imported goods are currently subject to the 15% Section 122 tariff. There are very limited exceptions. If any part of your supply chain involves imported goods - even components assembled in the US - tariff costs are likely embedded in your pricing.
"I'm a domestic-only reseller. Do tariffs affect me?"
Yes. Even if you never import anything directly, your suppliers do. Tariff costs flow through the entire supply chain. If your wholesaler imports goods or buys from importers, their costs went up - and those costs are reflected in the prices you pay.
Key Takeaways
- The double tax trap is real - You pay tariffs, then pay sales tax on the tariff amount
- Section 122 tariffs are 15% on all imports - Effective Feb 24, expiring July 24, 2026
- IEEPA refunds are coming - Register for CBP's ACH program and gather your import records
- Resale certificates eliminate the sales tax layer - Including the inflated tax caused by tariffs
- The de minimis exemption is gone - Every import, no matter how small, now carries duty
- Your suppliers are passing costs through - Even domestic resellers feel the impact
Protect Your Margins in 2026
You cannot control tariffs. You cannot control what Congress does next. But you can control whether you pay unnecessary sales tax on your inventory purchases.
A resale certificate is not a silver bullet - it will not eliminate your tariff costs. But it removes the sales tax layer entirely, including the extra tax you would pay on the tariff-inflated price. In an environment where every margin point counts, that matters.
