Company Formation Services in the United States
Starting a business in the United States requires navigating state-specific incorporation rules, IRS entity classification, and federal EIN registration.
Overview
Whether you are forming a Delaware LLC, a Texas S-Corporation, or a multi-member partnership, each structure carries distinct tax and liability implications under IRS guidelines. Fintax Support Limited helps founders choose the right entity, file Articles of Organization or Incorporation with the relevant Secretary of State, and obtain your EIN from the IRS. We also advise on state franchise tax obligations and operating agreement requirements so your US entity is compliant from day one.

Regulatory framework
US entity formation triggers ongoing obligations with both state Secretaries of State and the IRS. Most states require annual reports and franchise tax payments; failure to file can result in administrative dissolution. New entities must obtain an EIN before opening US bank accounts or hiring employees, and BOI reports must be filed with FinCEN within prescribed deadlines under the Corporate Transparency Act.

Our 50-state LLC formation service is built for real U.S. compliance conditions, not generic paperwork. We prepare and file Articles of Organization with the relevant Secretary of State, verify name rules, and align member or manager details for clean acceptance. After approval, we coordinate IRS Form SS-4 sequencing for EIN issuance and provide governance records needed for banking and vendor onboarding. Where applicable, we flag publication requirements, franchise tax obligations, and annual report deadlines. We also map formation data to FinCEN BOI requirements under the Corporate Transparency Act so new entities start with consistent state and federal records.

Our incorporation service supports both C-Corporation launches and S-Corp-ready structures with full federal and state coordination. We prepare Articles of Incorporation for Secretary of State filing, confirm registered agent requirements, and establish core corporate records such as incorporator actions and board resolutions. After state approval, we align IRS Form SS-4 submission for EIN issuance and handle Form 2553 planning when S-Corp tax treatment is selected. We also address shareholder eligibility constraints, stock structure implications, and ongoing annual report obligations. Where required, we connect ownership and control data to FinCEN BOI reporting workflows to keep Corporate Transparency Act compliance aligned.

We prepare EIN applications using IRS Form SS-4 with strict data matching to prevent downstream identity conflicts. Our team validates legal entity name, responsible party information, mailing address, and tax classification against Secretary of State records and formation documents before submission. Once the EIN is issued, we help synchronize federal credentials with payroll setup, W-9 workflows, and state account registrations where required. We also identify related obligations such as Form 2553 sequencing for S-Corp elections and FinCEN BOI readiness under the Corporate Transparency Act. The result is a reliable federal tax identity that supports clean onboarding and compliant operations.

Our registered agent and annual report service keeps U.S. entities compliant with recurring state obligations. We coordinate in-state agent coverage, monitor Secretary of State deadlines, and prepare annual report filings with current officer, address, and ownership details. For companies operating across several jurisdictions, we centralize due dates, fees, and acceptance evidence to prevent fragmented compliance. If deadlines are missed, we support catch-up and reinstatement strategy to recover good standing efficiently. We also assess whether ownership or control updates linked to annual maintenance should trigger FinCEN BOI amendments under the Corporate Transparency Act, helping keep federal and state records aligned.

We draft Operating Agreements and Corporate Bylaws that are practical for U.S. compliance and daily management. For LLCs, we structure capital contributions, allocation methods, distributions, transfer restrictions, and manager authority in a way that matches tax and control goals. For corporations, we formalize board authority, officer duties, voting mechanics, and shareholder approvals needed for disciplined governance. Documents are aligned with Secretary of State filings, IRS records, and election strategy, including Form 2553 implications where relevant. We also identify ownership or control provisions that may impact FinCEN BOI updates under the Corporate Transparency Act, reducing governance-to-regulatory mismatches later.

Our DBA and fictitious name registration service helps U.S. businesses use trade names without creating compliance risk. We identify the proper filing authority, which may be a Secretary of State office, county clerk, or local agency depending on jurisdiction. Applications are prepared to match legal entity records, EIN identity details, and active operating locations for clean approval and smoother bank or vendor onboarding. We also explain the boundary between DBA disclosure and trademark protection so businesses do not confuse the two. When ownership or control changes affect reporting records, we assess whether related FinCEN BOI updates under the Corporate Transparency Act should be handled in parallel.

Foreign qualification is essential when a U.S. company formed in one state begins operating in another. We analyze your hiring, contracting, office, and revenue footprint to identify where registration is required, then file authority applications with the relevant Secretary of State offices. Our team coordinates certificates of good standing, registered agent appointments, and assumed name filings where conflicts exist. We also map related obligations such as payroll tax registration, sales tax permits, and annual reports so qualification is not handled in isolation. If ownership or control changes occur during expansion, we align those events with FinCEN BOI update obligations under the Corporate Transparency Act.

BOI Reporting (FinCEN / Corporate Transparency Act)
Meet U.S. BOI requirements confidently with structured FinCEN reporting support. We identify whether your entity is a reporting company, gather required beneficial owner data, and file accurately under Corporate Transparency Act rules.

Our BOI reporting service helps U.S. entities comply with FinCEN requirements under the Corporate Transparency Act without guesswork. We assess whether your company is a reporting company, identify possible exemptions, and compile required data for beneficial owners and company applicants. Before submission, we reconcile entity details against Secretary of State records and IRS identity information to avoid inconsistent filings. We then file through the FinCEN system and document confirmations for compliance records. Because BOI obligations continue after the initial filing, we also implement update controls for ownership transfers, leadership changes, and other reportable events that may require timely amendments.

We verify eligibility requirements, including shareholder limits, owner status, and permissible equity structure, before preparing the election package. The filing is timed to match your intended tax year and coordinated with EIN records so IRS processing is smoother. If deadlines were missed, we can support late election relief documentation where applicable. After acceptance, we help implement reasonable compensation and distribution controls to keep treatment defensible. We also monitor ownership changes that could affect S-Corp eligibility and whether those events require related FinCEN BOI updates under the Corporate Transparency Act.

For businesses expanding across jurisdictions, we phase registrations to match growth and monitor ownership or control changes that may also require FinCEN BOI updates under Corporate Transparency Act rules.
