The foundation of any correct filing is knowing exactly which entity will be reported and its real operational status.
Vulpe guide for Non-Resident LLCs
U.S. Tax Guide for LLCs and Non-Residents
Strategic guide for Non-Resident LLCs: what to review, what to file, and how to avoid structural mistakes before filing.
- A clear framework before filing
- Real differences depending on the state
- Process, deliverables, and service limits
Tax Season 2026
What to review before filing taxes correctly
The structure changes depending on who owns it, how they participate, and their relationship with the LLC during the period.
An inactive LLC is not the same as one with movement, and U.S.-source income is not the same as non-U.S. income.

Who this guide is for
This material is designed for LLC owners who need real context before filing.
- Owners of U.S. LLCs who live outside the United States (Non-Residents)
- Single Member and Multi Member LLCs
- Companies with or without activity during the tax year
- People who have filed before but are not sure if it was done correctly
- Those who want to understand what Tax Season involves before filing
- Businesses that need clarity on federal and state obligations
If you have an LLC and want to stay compliant, this guide is for you.
Who this guide is not for
This does not replace a diagnosis and is not for shortcuts or generic solutions.
- U.S. tax residents, because different rules apply
- People seeking tax evasion or “shortcuts”
- Cases requiring tax litigation or legal defense
- Companies that already have an internal CPA managing all compliance
- Those expecting a generic solution applicable to every case
Every situation is different. The goal is not to oversimplify, but to avoid mistakes caused by lack of context.
What problem this guide solves
Organize the confusion before executing the filing
This page solves a very specific confusion: understanding what Tax Season really means for a Non-Resident LLC and how to comply correctly without improvising.
- Understand what must be reported and why
- Distinguish between the obligation to report and the obligation to pay
- Identify which forms apply according to the LLC type
- Understand why the state where the LLC was formed really matters
- Avoid decisions made “just in case” or with incomplete information
- Have a clear framework before filing any return
Requirements
What is actually needed to file taxes correctly
Correctly filing for a Non-Resident LLC requires complete and coherent information. Without this data, any filing becomes an estimate, and that is a risk.
Basic LLC information
01
Full legal name of the LLC
02
State of formation
03
Date of formation
04
Active EIN
05
Registered address
06
Good standing confirmation
This block corresponds to the LLC’s legal and administrative foundation. If this part is incomplete, the entire filing loses precision from the beginning.
Tax period information
01
Tax year to be filed
02
Confirmation of activity or inactivity
03
Start date of operations, if applicable
Here we define exactly which period will be reported and whether there was real activity or inactivity during that year.
Owner information
01
Full legal name
02
Country of tax residence
03
Ownership interest in the LLC (Single or Multi Member)
04
Date joined as member
05
ITIN, if applicable
The owners’ tax identity changes the analysis. It is not enough to know who owns it: how they participate and where they are taxed matter.
Operational information
01
How revenue was generated
02
Source of income (U.S. or non-U.S.)
03
Platforms used, if applicable
04
Associated bank accounts
05
Approximate yearly movement
This block helps understand how the LLC operated during the year and how the activity relates to the United States or to non-U.S. income.
State compliance
01
Confirmation of Annual Report filed or pending
02
State-specific obligations
03
Franchise Tax (if applicable in Delaware)
Beyond the federal level, this validates whether the state requires an Annual Report, Franchise Tax, or other obligations that should not be confused with IRS filing.
Before filing
These are the points reviewed before defining the filing
Filing without this prior analysis is one of the main sources of errors. The filing does not define the structure. The filing reflects what already exists.
General LLC analysis
We review the type of LLC, the owner’s status, the tax year to be filed, whether there was activity, and how revenue was generated.
This analysis helps define the correct federal framework.
Operational analysis
We analyze where the business operates from, which markets it targets, how it collects and pays, and how accounts and platforms are connected.
This is where risks of inconsistency between operations and filing are identified.
Analysis by state of formation
We validate whether additional state obligations exist, which reports apply, and how Annual Report and good standing relate to the filing.
Not all states treat an LLC the same way. Assuming “it is the same for everyone” creates errors.
State of formation
Key differences by state
Although federal filing with the IRS follows common rules, the state where the LLC was formed changes obligations, deadlines, and risks. Understanding these differences is essential before filing.
Florida requires clear control between federal and state compliance.
- There is an obligation to file a state Annual Report
- There are specific deadlines that do not match IRS deadlines
- Failure to file may affect good standing
- Common mistake: confusing tax with administrative reporting
The Annual Report in Florida follows a fixed annual calendar and, if filed late, the penalty is automatic and usually not negotiable.
Delaware requires clear separation between compliance levels.
- Franchise Tax obligation
- State compliance independent from the IRS
- Common errors due to lack of calendar awareness
- Non-compliance affects the legal validity of the LLC
Delaware does not tax the Non-Resident’s operation, but it does require compliance with its own reports.
Wyoming is simple on taxes, but strict on compliance.
- Annual Report required, even without activity
- The focus is keeping the LLC active and in good standing
- Common confusion: assuming “there is nothing to do”
- Non-compliance can generate unnecessary alerts
In Wyoming, the risk is usually not tax-related, but operational.
Step by step
How the process works
The tax process for a Non-Resident LLC does not start with the return. It starts with the right analysis.
01
Diagnostic consultation
We review the general situation of the LLC, the owner’s status, the type of activity, and the state of formation. This is where risks, obligations, and real scope are identified.
02
Identification of LLC type and applicable treatment
We determine whether the LLC is Single Member or Multi Member and how it should be treated federally. Not all LLCs file the same way.
03
Review of activity and income source
We analyze whether there was activity, how the income was generated, and its relationship with the United States. This defines what must be reported.
04
Definition of applicable forms and reports
With the information clear, we define which forms must be filed and which do not apply. State obligations are also considered here.
05
Filing and confirmation
The corresponding filing is submitted and filing confirmation is delivered. The process closes only when everything has been properly filed.
Deliverables
