How is an American LLC structured?
An American LLC is made up of various documents, many of which are optional and flexible, i.e. modifiable at will once your USA LLC is opened.
An American LLC consists of an Incorporation number
A USA LLC has an incorporation number called a Filing Number, this number identifies your company with the State of Opening and is needed to pay for renewals with the State if required, apply for licenses or DBAs, Doing Business As.
An American LLC consists of a Certificate of Organization
Once incorporated, an American LLC receives from the State in which it was incorporated a Certificate of Organization or Certificate of Organization, which declares who is the founder, the organizer and the Resident Agent.
For the Statute of Organization it is necessary:
A US LLC may have an operating agreement
Better known as an Operating Agreement, although optional it is the more important document. An LLC operating agreement is a legal document that defines the rights and responsibilities of each LLC member and describes the operating terms of the organization. Many states require LLCs to have an operating agreement. While an operating agreement is not required in all states, we recommend that you have one.
A US LLC requires a Resident Agent or Legal Representative
A resident agent is a third party, registered in the same state in which the business is established. The resident agent is appointed to receive and send official documents on your behalf, such as filings, official government notifications, tax forms, and notice of lawsuits.
If you incorporate in the state where you live, you can be the resident agent for the business yourself, otherwise you will need to use for example us acting as the US resident agent.

Where to open accounts and how to set up a US LLC
American LLC and accounting compliance
What tax obligations does the American LLC have?
The opening of an American LLC is just the tip of the iceberg of a wider process. federal obligations and may or may not have state tax obligations (local or in the state in which the LLC is incorporated). We recall that the United States is a federation of States, each independent from the other in terms of taxation and each one has or less taxes and charges that are not present or are present in a different way in others.
For businesses, opening a company in the United States does not mean not paying taxes. It means incorporating a legal entity governed by the laws of that state and, therefore, proceeding to pay federal taxes, as in any other state. Furthermore, in the United States state taxation is based on economic presence (sales and customers, even without physical presence in the state), the so-called economic nexus . Among the examples, in California this criterion is considered for every company that has a turnover exceeding 200,000 dollars.
At the Federal Level, all LLCs, regardless of the state in which they are opened, are required by law to file forms with the IRS before the end of the tax year. For US Foreign Owned LLCs, that is, those 100% owned by foreigners who are not residents of the United States, LLCs are required to prepare and send forms 5472 and 1120 to the IRS, Internal Revenue Service.
Submitting these forms does not trigger any federal tax or accounting obligations, and therefore does not generate any tax collection. It is merely a bureaucratic and financial requirement with no tax implications. We provide accounting services for this purpose upon request. Opening a US LLC therefore requires completing IRS Forms 5472 and 1120, but never requires paying taxes in the US because the LLC is foreign-owned.
We always recommend that anyone wishing to open an American LLC obtain an American ITIN in addition to the EIN, as this simplifies various American bureaucratic procedures when it comes to solving or completing corporate paperwork (mortgages, loans, credit cards, etc.).
Consider opening an American LLC only the first step of many others to add to the "corporate package" to be 100% sure of putting you in the best conditions to work without problems in the future.
If you are interested in American LLCs, contact us. Furthermore, do not forget that operating offshore requires being suitably covered with an adequate new tax residence in a country with territorial taxation such as a Residence in Panama or a Residence in Paraguay.

With the NHR Portugal program, you are not required to meet any minimum or maximum number of days in Portugal to qualify for residency. You will be able to optimize your NHR in Portugal by establishing an American LLC.
The aim of the NHR program is to attract investors, professionals and high net worth individuals to contribute to Portugal's economy and culture.

By becoming a NHR resident in Portugal with a U.S. LLC, you can benefit from a flat income tax rate of 20% on qualifying income for 10 years instead of paying higher taxes in your home country.
This flat income tax rate is lower than the tax rates typically imposed by Portugal and is also significantly lower than US tax rates, in the case of particularly high incomes.
