Every Proof of Address Document for a US LLC: Lease, Utility Bills, and Nexus Templates Compared
Banks, Amazon, and the IRS each accept different proof-of-address documents. This guide compares every document type — commercial lease, water bill, electric bill, gas bill, ISP/broadband bill, business utility account, bank statement, insurance certificate, and government letter — with platform-by-platform acceptance and nexus implications.
TL;DR
Every US financial institution, platform, and tax authority requires proof of address but accepts a different mix of documents. The hierarchy from strongest to weakest: commercial ISP/broadband bill > electric or gas bill > water bill > executed sublease agreement > bank statement > insurance certificate > government letter. A commercial sublease plus an ISP bill covers all platforms simultaneously. For nexus purposes, any document proving regular business operations at a physical address can establish sufficient physical presence under state tax law.
Why Document Type Matters More Than Most Founders Expect
"Proof of address" sounds like a single category. It is not. Each institution has developed its accepted document list based on the fraud patterns it has actually encountered. An IRS agent, a Mercury compliance officer, and an Amazon verification reviewer have each seen different types of fake documents — and their acceptance lists reflect what they have learned.
The result is a fragmented landscape: a document that satisfies your bank may not satisfy Amazon. A document that satisfies Wise may not satisfy your state tax authority for nexus registration. Understanding the full document hierarchy — and which platform accepts which — prevents the situation where you have the wrong document on hand at the critical moment.
This guide covers every document type, what makes each one valid or invalid, which platforms accept it, and what each document implies for tax nexus purposes.
Document Type 1: Commercial Lease Agreement
A commercial lease agreement is a legally binding contract between a tenant (your business) and a property owner, establishing tenancy rights at a specific commercial address.
What makes it valid:
- Signed by both tenant (your business entity name) and landlord or authorized master tenant
- Lists the specific suite number and full address including ZIP code
- States the lease term (start date, end date or renewal clause)
- Is traceable to a real property owner via county assessor records
- Reflects a real commercial property (commercially zoned, not residential)
What makes it invalid or weak:
- Signed between two entities without a traceable landlord-to-building chain
- Lists only a building address without a suite number (indistinguishable from a registered agent address)
- No termination date or clearly expired
- Signed by a management company with no verifiable connection to the property
Platform acceptance (2026):
| Platform | Accepts lease alone | Notes |
|---|
| Mercury | Usually | Sublease or direct lease; must name your entity |
| Wise (NRA) | Rarely | Requires utility bill in addition for non-residents |
| Relay | Yes | Lease is primary document |
| Amazon Seller Central | No | Amazon requires utility bill — lease alone rejected |
| Traditional banks | Partial | Lease plus utility bill both required |
| IRS (ITIN, EIN) | Yes | Lease or any US address evidence accepted |
| Wyoming SOS | Yes | Any commercial address accepted |
Nexus implication: A signed commercial lease establishes that your business has the legal right to occupy space in that state. Most state revenue departments treat a lease in your business's name as evidence of physical presence, which can trigger nexus for sales tax and income tax purposes. Wyoming has no state income tax and no general sales tax, so Wyoming nexus does not create state tax liability. If you operate in other states through the Wyoming LLC, the Wyoming address alone does not create nexus in those states.
Document Type 2: Commercial ISP / Broadband Bill
A commercial ISP bill is a monthly statement from a business-class internet service provider showing your business entity name, service address, account number, and billing period.
What makes it valid:
- Business entity name (not personal name) on the account
- Service address includes suite number
- Issued by a recognized commercial ISP (Spectrum Business, AT&T Business, Lumen, Comcast Business)
- Original carrier statement — not a screenshot, online portal export, or summary letter
- Dated within 90 days of submission
- Account is active (not past-due or cancelled)
What makes it invalid:
- Personal name on account instead of business name
- Residential-tier ISP service (Spectrum Residential vs. Spectrum Business are different products)
- Printed confirmation or activation letter instead of monthly bill
- Mobile broadband or hotspot account (not fixed-location commercial service)
- Dated more than 90 days before submission
Platform acceptance: Highest-acceptance document across all platforms. Accepted by Mercury, Wise, Relay, Amazon, Stripe, PayPal, traditional banks, and state tax authorities.
Nexus implication: A commercial ISP account in your business name at a specific address is strong evidence of regular physical business operations. Courts and state revenue departments have consistently found that a dedicated business communication line at an address supports a finding of physical presence and nexus.

Document Type 3: Electric Bill
A commercial electric bill from a utility company in your business entity's name at your suite address.
What makes it valid:
- Business entity name on account
- Suite address including suite number
- Issued by state-regulated electric utility (Rocky Mountain Power, Black Hills Energy in Wyoming)
- Original monthly statement with account number
- Dated within 90 days
What makes it weak:
- Residential account rate (commercial accounts are classified differently in utility company records)
- Shared utility account in landlord or building name — not your business
Platform acceptance: Accepted by all platforms that accept ISP bills. Some banks slightly prefer ISP bills as they are harder to share among tenants (each ISP account is a distinct line), but electric bills from the business's own account are equally strong.
Nexus implication: An electric account in your business's name is among the strongest nexus indicators. It proves ongoing financial commitment to operations at the address — you are paying to keep the lights on for your business specifically.

Document Type 4: Gas Bill
Commercial gas utility account in the business entity name.
What makes it valid:
- Same criteria as electric bill (business name, suite address, utility company statement, within 90 days)
- Commercial-rate account
Platform acceptance: Accepted by most banks and platforms. Less common in office settings than ISP or electric, but equally valid when available.
Nexus implication: Same as electric — strong physical presence indicator.

Document Type 5: Water Bill
Municipal water account in the business entity name at the business address.
What makes it valid:
- Business entity name on account
- Issued by city or county water authority
- Suite or unit number on account where applicable
Limitations: Water accounts are less commonly available at individual suite level in multi-tenant commercial buildings. The water account is typically in the building owner's name for the entire building, not broken down by tenant. If water service is sub-metered per suite, the account may be available in your name; if not, this document type may not be accessible regardless of your lease.
Platform acceptance: Accepted where available, but less frequently obtained in commercial office settings than ISP or electric. Banks and Amazon accept it, but ISP or electric bills are easier to obtain.

Document Type 6: Business Utility Account Statement
Some states and cities offer combined utility service programs or specific commercial utility accounts that do not fit neatly into the ISP/electric/gas/water categories. These include:
- Telecom bundles (voice + internet + other services)
- Building service subscriptions (HVAC maintenance contracts, elevator service, janitorial contracts)
- Municipal business service accounts
Platform acceptance: Varies. ISP components of a telecom bundle are generally accepted. Non-ISP business services (HVAC, janitorial) are not accepted as primary proof of address at banks or Amazon but may support nexus documentation for tax purposes.

Document Type 7: Bank Statement
A statement from a previously opened bank account, in the business entity's name, showing the address on file.
What makes it valid:
- Business entity name on statement
- Address shown matches the address you are proving
- Statement dated within 90 days
- Issued by a regulated US bank or credit union
Limitation: A bank statement proves that a bank previously accepted this address — it does not independently prove that the business operates there. Banks are generally reluctant to accept a bank statement as primary proof of address because the address on the statement was itself only verified at the time the bank account was opened, using whatever documents were accepted then. This creates a circular verification problem.
Platform acceptance: Used as secondary or supplementary proof. Not accepted as primary proof of business address at Mercury, Wise, or Amazon.
Document Type 8: Insurance Certificate
A Certificate of Insurance (COI) showing commercial general liability or business owner's policy coverage at the specific business address.
What makes it valid:
- Business entity name as insured
- Address of insured operations includes your suite
- Issued by a licensed US insurance carrier
- Certificate of Insurance (ACORD 25 form is standard)
Platform acceptance: Accepted by some banks as supplementary evidence. Not accepted by Amazon. Insurance certificates are more commonly used in B2B contexts (proving coverage to clients and landlords) than for bank account KYC.

Document Type 9: Government Agency Letter
A letter from a US government agency — IRS, state secretary of state, state tax authority, or municipal licensing office — addressed to your business at your business address.
Examples:
- IRS EIN confirmation letter (CP-575 or SS-4 confirmation)
- IRS correspondence sent to the business address
- Wyoming Secretary of State filing acknowledgment
- Wyoming Department of Revenue correspondence
- City of Cheyenne business license
What makes it valid:
- Addressed to your business entity at your specific suite address
- Issued by an official government body with a verifiable letterhead
- Not expired or superseded by a more recent filing
Platform acceptance: Government letters are high-trust documents that are widely accepted. The IRS EIN letter is often listed alongside the Articles of Organization as a primary business document. State agency letters are accepted as proof of business address at most banks.

Nexus: When Your Address Creates Tax Obligations
Physical nexus is the connection between your business and a state that requires you to comply with that state's tax laws (sales tax collection, income tax filing, business registration).
When a Wyoming address creates Wyoming nexus: Always. Your Wyoming LLC with a Wyoming address has nexus in Wyoming by definition. However, Wyoming has no state income tax and a limited sales tax that applies to physical goods sold in Wyoming — not to most online services or digital products.
When a Wyoming address triggers nexus in OTHER states: Generally, it does not — unless you also have employees, inventory, or property in those states. The Wyoming address establishes Wyoming nexus only. Cross-state nexus requires a physical connection to each state independently.
Document implications: For nexus registration or audit defense purposes, the strongest documentation package is: commercial lease + utility bill + bank statement showing regular business transactions. This is the three-document proof-of-operations package that state revenue departments look for when evaluating nexus claims.
Key nexus triggers and the documents that prove them:
| Nexus trigger | What it means | Documents that prove it |
|---|
| Physical office presence | Regular business operations at a fixed address | Lease + utility bill |
| Employee in state | Payroll records, W-2, employment contract | Payroll docs |
| Inventory stored in state | Amazon FBA, warehouse | FBA inventory report, warehouse contract |
| Economic nexus (sales threshold) | $100,000 sales or 200 transactions in state | Sales records |

Frequently Asked Questions
Q: Which document is the single strongest proof of address for all platforms?
A commercial ISP bill (Spectrum Business, AT&T Business, Lumen) in your business entity's name at your suite address. It is accepted by Mercury, Wise, Amazon, traditional banks, and state authorities. It is independently verifiable by calling the carrier. It proves ongoing physical operations.
Q: Can I use a utility letter instead of a utility bill?
No — not for Wise or Amazon. A utility letter is an attestation from the provider, not an original billing statement. Wise and Amazon specifically require the original monthly carrier statement with account number and billing cycle. Banks are more flexible but prefer original statements.
Q: Do I need all of these documents to open a bank account?
No. For Mercury, a sublease agreement alone usually suffices. For Wise as a non-resident, a sublease plus an ISP bill covers the requirement. For Amazon, an ISP or electric bill within 90 days is required. Get the sublease and ISP bill first — that combination covers all major platforms.
Q: Does a Wyoming address create sales tax nexus in Wyoming?
Wyoming has a 4% state sales tax that applies to physical goods sold to Wyoming residents. If your Wyoming LLC sells goods within Wyoming, you have nexus. If your LLC sells services or digital products, Wyoming sales tax generally does not apply. If you only use the Wyoming address for business registration and banking, and your customers are not in Wyoming, Wyoming sales tax does not apply to those sales.
