Does having FBA inventory in Arizona mean I have physical nexus even if Amazon handles the tax?

Yes. Physical presence of inventory in an Arizona fulfillment center creates physical nexus under traditional nexus principles — this is entirely separate from the marketplace facilitator statute. Amazon's collection of TPT on facilitated sales does not eliminate your physical nexus or your independent obligation to hold a TPT license. Physical nexus triggers the requirement to be registered; the facilitator statute determines who remits tax on specific transactions. These are two distinct legal frameworks that operate simultaneously.

Can I use Arizona's voluntary disclosure program if I have unreported FBA nexus?

Yes. The Arizona Department of Revenue (ADOR) accepts voluntary disclosure agreements (VDAs) from sellers who have had unreported nexus. A VDA typically limits lookback liability to 3-4 years, waives penalties, and may reduce interest. For FBA-only sellers whose tax was already remitted by Amazon as a marketplace facilitator, the practical exposure is minimal — but the registration gap itself can trigger penalties. Contact ADOR's Voluntary Disclosure Unit or work through the Multistate Tax Commission's (MTC) National Nexus Program to initiate the process.

If I sell on both Amazon and Etsy and both are marketplace facilitators, do I still owe Arizona TPT?

If 100% of your Arizona-delivered sales flow through registered marketplace facilitators (Amazon, Etsy, eBay, Walmart), those facilitators handle TPT collection and remittance on those transactions. However, you still have an independent obligation to hold a TPT license if you have physical nexus (FBA inventory) or economic nexus ($100,000 threshold). The license requirement exists separately from the remittance obligation. On your TPR return, you would report gross sales and deduct facilitator-remitted amounts, resulting in $0 net tax due — but you must still file.

What is the penalty for not having an Arizona TPT license when I have FBA inventory in the state?

Operating without a required TPT license in Arizona can result in penalties of up to $1,000 per location per month under A.R.S. § 42-5008. Additionally, ADOR can assess back taxes, interest (currently 3% above the federal prime rate), and a late-filing penalty of 4.5% per month up to 25% of tax due. For FBA-only sellers where Amazon already remitted the TPT, the back-tax exposure is limited to non-facilitated sales — but the licensing penalty applies regardless of who remitted the tax.

Does Arizona aggregate all marketplace sales when measuring the $100,000 economic nexus threshold?

Yes. Arizona counts all retail sales of tangible personal property, electronically delivered goods, and taxable services delivered into the state — regardless of whether a marketplace facilitator collected TPT on those sales. Your Amazon FBA sales, Etsy sales, eBay sales, and direct website sales all count toward the $100,000 threshold. Once crossed, you have economic nexus and must register for a TPT license even if facilitators already handle tax on all of those transactions.

Arizona TPT and Amazon FBA: Does Marketplace Facilitator Status Cover Your FBA Inventory Stored in Arizona?

Arizona's marketplace facilitator law — A.R.S. § 42-5043 — requires Amazon to collect and remit Transaction Privilege Tax (TPT) on all facilitated sales shipped to Arizona addresses. For sellers using Fulfillment by Amazon (FBA), this means Amazon handles the tax on every order placed through Amazon.com. But here's the problem most FBA sellers miss: inventory stored in an Arizona fulfillment center creates physical nexus entirely independent of the facilitator statute. Physical nexus triggers a TPT license requirement — and that requirement exists whether or not a marketplace facilitator is already remitting tax on your sales. The facilitator statute determines who remits. Physical nexus determines who must be registered. These are two separate legal obligations, and satisfying one does not discharge the other.

Key Takeaways

• Amazon is a confirmed marketplace facilitator in Arizona under A.R.S. § 42-5043 — it collects and remits TPT (state + county + city) on all facilitated orders
• FBA inventory in Arizona creates physical nexus independently — this triggers a TPT license requirement regardless of facilitator remittance
• A seller with 100% Amazon FBA sales still needs a TPT license if inventory is stored in AZ — the license requirement is separate from the collection obligation
• ADOR accepts voluntary disclosure agreements for sellers with unreported FBA nexus — typically limiting lookback to 3-4 years with penalty waivers
• Multi-channel sellers (Amazon + Etsy) are not fully covered — you must still register and file even if all channels are facilitator-covered, and non-facilitated sales require independent collection
• Arizona's $100,000 economic nexus threshold counts all sales — including facilitator-remitted transactions — when measuring whether you must register

How Arizona Defines “Marketplace Facilitator” Under A.R.S. § 42-5043

Arizona enacted its marketplace facilitator provisions effective October 1, 2019, as part of the state's post-Wayfair economic nexus framework. Under A.R.S. § 42-5043, a marketplace facilitator is defined as a person who contracts with marketplace sellers to facilitate the retail sale of tangible personal property or taxable services through a marketplace — and who directly or indirectly collects payment from the purchaser, transmits payment to the seller, or owns or operates the infrastructure through which sales are facilitated.

The statute further specifies that a marketplace facilitator with $100,000 or more in annual gross revenue from retail sales into Arizona must collect and remit TPT on all facilitated sales. Since Amazon's Arizona-delivered sales far exceed this threshold, Amazon is perpetually obligated to collect TPT on all orders placed through its marketplace — including FBA, Seller Fulfilled Prime, and Merchant Fulfilled orders listed on Amazon.com.

Amazon's confirmed status: Amazon has been registered as a marketplace facilitator in Arizona since October 1, 2019. It collects the full combined TPT rate — which varies by city and county but averages roughly 7.8% to 8.6% across major Arizona locations (e.g., 8.6% in Phoenix, 8.05% in Scottsdale, 7.8% in Tucson). Amazon remits directly to ADOR and files TPT returns on behalf of the facilitated sales.

Why FBA Inventory Creates Physical Nexus in Arizona Independent of the Facilitator Statute

Physical nexus in Arizona is established when a seller has tangible personal property — including inventory held for sale — stored within the state. This is a traditional nexus principle predating both Wayfair and the marketplace facilitator statute. When Amazon stores your FBA inventory at one of its Arizona fulfillment centers (such as PHX3, PHX5, PHX6, or PHX7 in the Phoenix metro area), your property is physically present in Arizona. That physical presence creates nexus for your business.

Key distinction: The marketplace facilitator statute (A.R.S. § 42-5043) determines who collects and remits TPT on specific transactions. Physical nexus under traditional principles determines who must hold a TPT license and be registered with ADOR. These are parallel legal frameworks:

Legal Framework	What It Determines	Triggered By	Obligation
Marketplace Facilitator (A.R.S. § 42-5043)	Who remits TPT on facilitated sales	Sale made through a marketplace	Facilitator collects and remits
Physical Nexus (traditional)	Who must hold a TPT license	Inventory stored in AZ	Seller must register with ADOR
Economic Nexus ($100K threshold)	Who must hold a TPT license	$100K+ in AZ-delivered sales	Seller must register with ADOR

The practical implication: Even if Amazon remits TPT on every single one of your Arizona sales, you still need to be registered with ADOR if your inventory is stored there. Registration is a legal requirement triggered by nexus — not by whether you personally owe tax on specific transactions. Think of it this way: the TPT license is your business's acknowledgment that it has taxable presence in Arizona. The marketplace facilitator statute merely shifts the collection burden for specific transactions to the platform.

You cannot control where Amazon stores your FBA inventory. Amazon distributes inventory across its fulfillment network based on demand forecasting. If you ship products to FBA, Amazon may place them in Arizona without your explicit approval. Check your FBA Inventory Placement reports regularly — if inventory appears in an Arizona facility, you have physical nexus from that date forward.

Does a Seller with 100% Amazon FBA Sales Still Need a TPT License?

Yes. If you sell exclusively through Amazon FBA and Amazon stores your inventory in Arizona, you need a TPT license — even though Amazon collects and remits TPT on every one of your transactions. Here is the logic:

Physical nexus trigger: Inventory in Arizona = physical nexus = TPT license required
Facilitator coverage: Amazon remits TPT on all Amazon.com orders = $0 net tax due on your TPR return
Filing obligation: You must file TPR returns (even if showing $0 net due) because you hold a TPT license

The practical outcome for a 100% FBA-only seller is a TPT license with $0 remittance on each filing — you report gross Arizona sales, deduct the facilitator-remitted portion (100% in this case), and the net result is zero. But the registration and filing requirements remain. Failing to register exposes you to licensing penalties under A.R.S. § 42-5008 regardless of whether any actual tax was left unpaid.

Why Does Arizona Require This?

ADOR's position is that the TPT license requirement is tied to taxable presence — not to whether tax is currently owed. A business with physical nexus in Arizona may begin non-facilitated sales at any time (adding a Shopify store, selling at trade shows, taking wholesale orders). The license ensures ADOR has the business in its system and can monitor compliance across all sales channels. It also ensures the business is subject to audit authority should questions arise about the accuracy of facilitator-reported amounts.

ADOR Guidance: Voluntary Disclosure vs. Standard Registration for FBA-Only Sellers

If you've had FBA inventory in Arizona for months or years without a TPT license, you have two paths to come into compliance: standard registration (apply today and begin filing forward) or voluntary disclosure agreement (VDA) (negotiate with ADOR to resolve past-period liability before registering).

Approach	Best For	Lookback Period	Penalty Treatment
Standard Registration	Sellers with less than 12 months of unreported nexus; 100% facilitator-covered sales	No formal lookback — but ADOR retains audit rights for open periods	Possible late-registration penalty; no guaranteed waiver
Voluntary Disclosure Agreement (VDA)	Sellers with 1+ years unreported nexus; any non-facilitated sales during that period	Typically limited to 3-4 years	Penalties waived; interest negotiable; clean start

For FBA-only sellers with 100% facilitator coverage: The VDA path is most valuable if you've had unreported nexus for more than one year. Even though Amazon remitted TPT on all your sales, the licensing violation itself can carry penalties. A VDA provides a documented resolution and a clean compliance start date.

How to initiate a VDA: You can apply directly to ADOR's Voluntary Disclosure Unit, or go through the Multistate Tax Commission's (MTC) National Nexus Program, which allows anonymous initial contact. The MTC process is preferred when you're uncertain about your exposure level and want to understand ADOR's likely response before identifying yourself.

Do not register first and then attempt a VDA. Once you register with ADOR, you are in their system with a known start date. The voluntary disclosure process requires that you have not already registered or been contacted by ADOR about the specific tax type. If you're considering a VDA, consult a tax professional before taking any action with the state.

Risk Scenario: Selling on Amazon + Etsy — Does Combined Facilitator Remittance Eliminate Your TPT Obligation?

Consider this common scenario: You sell handmade products on both Amazon FBA and Etsy. Both platforms are registered marketplace facilitators in Arizona. Both collect and remit TPT on their respective orders. Does this mean you're fully covered with no independent TPT obligation?

Not entirely. Here's why:

Channel	AZ Revenue (12 months)	Facilitator Collects?	Your Direct TPT Obligation
Amazon FBA	$70,000	Yes — Amazon remits	$0 (covered by Amazon)
Etsy	$40,000	Yes — Etsy remits	$0 (covered by Etsy)
Total into AZ	$110,000	—	$0 remittance due

In this scenario, your net TPT remittance is $0 — both facilitators have handled collection. But you still have obligations:

TPT license: Required because FBA inventory creates physical nexus (and $110K exceeds the $100K economic nexus threshold independently)
TPR filing: Required on your assigned schedule — report $110K gross, deduct $110K facilitator-remitted, net $0
Audit exposure: ADOR can audit to verify that facilitator-reported amounts match your actual sales

The Real Risk: Adding a Non-Facilitated Channel

The scenario becomes materially risky when you add a direct sales channel. Suppose you launch a Shopify store and make $15,000 in Arizona sales:

• Amazon remits on $70K — covered
• Etsy remits on $40K — covered
• Shopify $15K — YOUR responsibility to collect and remit TPT

If you weren't registered when you launched the Shopify store, you owe back TPT on the $15K plus penalties and interest. This is why registering proactively — even with $0 net due from facilitator-covered sales — protects you when your channel mix changes.

Frequently Asked Questions

Yes. Amazon is a registered marketplace facilitator in Arizona under A.R.S. § 42-5043 and collects the applicable Transaction Privilege Tax (state + county + city) on all orders placed through Amazon.com and shipped to Arizona addresses. This includes FBA orders, Seller Fulfilled Prime orders, and Merchant Fulfilled orders listed on Amazon's marketplace. Amazon handles the full collection and remittance cycle for these facilitated sales — you will not see a separate TPT line item in your Amazon settlements for AZ orders.
