Your company in the United States, with Contaldia

We are expanding our services: you can now set up your company in the United States and file its federal taxes with us. Two packages, optional operational services and rates in US dollars (USD).

If you already have clients, suppliers or a company in the US, or want to open one, here is what we do and how much it costs.

Two packages

Company Formation and Annual Tax Compliance

USD 1,950 / year

To establish your presence in the US and keep your federal tax obligations up to date:

  • State registration (LLC or Corporation).
  • EIN application.
  • Federal tax filings according to your structure: Form 1040-NR + Schedule C, Form 1120, Form 1065, Schedule K-1 and Form 5472.

Does not include monthly bookkeeping or quarterly estimated tax payments.

Full-Service Accounting and Tax Compliance

USD 795 / month

Everything above, plus continuous accounting and tax support throughout the year:

  • Monthly bookkeeping.
  • Federal tax compliance and annual returns, with Form 5472 when applicable.
  • Quarterly estimated tax payments and tax compliance monitoring.
  • Up to 4 hours of consulting per month with our team.

The price may be adjusted according to transaction volume.

Operational services

They can be hired together with any of the packages, at a monthly fee:

  • USD 420/month · Payroll management.
  • USD 490/month · Accounts payable management.
  • USD 560/month · Accounts receivable management.

The payroll fee covers our professional fees only: payroll software, state compliance fees, employer taxes and contributions, and employee tax withholdings are invoiced separately.

With variable fees depending on the state and the company: annual state renewal, registered agent service and a US business address.

Services quoted separately

Depending on complexity, state and each client's needs:

  • ITIN application.
  • Dissolution and closure of an LLC or Corporation.
  • Assistance opening a US business bank account.
  • Foreign Qualification: registration in other states to operate outside the state of formation.
  • State Tax and Sales Tax registration.

Government fees and third-party costs are also quoted separately.

Each case is reviewed first

In the US each state has its own rules. Before a final proposal we assess your case: Sales Tax, economic and physical nexus in other states, Foreign Qualification and companies with complex structures, multiple entities or a high volume of transactions. For companies with low financial activity we may apply discounts.
