IRS Certified Acceptance Agent (CAA)
CompanyVista's founder holds IRS CAA status — one of fewer than 5,000 globally. ITIN applicants do not need to surrender their original passport to the IRS. Documents are verified by our CAA and certified copies submitted — your passport stays with you throughout the process.
📞
EIN for Non-Residents — We Handle the IRS
Non-residents cannot use the IRS online EIN portal — it is restricted to US Social Security Number holders. CompanyVista handles the full SS-4 preparation and IRS submission via fax or direct IRS phone line, which requires speaking with IRS personnel directly. We manage this entirely.

EIN, ITIN, VAT (UK/EU/UAE), GST (Singapore, Australia, Canada, New Zealand, India), UTR, UEN, ABN, BN and all other mandatory business tax registrations — handled by the same CompanyVista team that registered your company. No handoffs, no starting over.

Every Tax ID Your Company Needs

All government tax IDs are issued free of charge by the relevant authority — there is no government fee for any of the IDs listed below. CompanyVista's professional fee covers the preparation, submission and follow-up — confirmed in a written quote before any payment.

VAT
Value Added Tax Registration
VAT registration is required when a business's taxable turnover exceeds the jurisdiction's threshold — or voluntarily below that threshold (which is often beneficial for input tax reclaim). Non-resident businesses supplying taxable goods or services in a jurisdiction may be required to register regardless of turnover.

CompanyVista handles VAT registration in the UK (HMRC), UAE (Federal Tax Authority), all 27 EU member states and via the EU One Stop Shop (OSS) for pan-EU e-commerce businesses. Making Tax Digital (MTD) compliant filing is set up alongside UK VAT registration.

Goods & Services Tax Registration
GST registration is required when a company's taxable turnover exceeds the local threshold. Thresholds vary significantly by jurisdiction. CompanyVista handles GST registration in Singapore (IRAS), Australia (ATO), Canada (CRA), New Zealand (IRD) and India (GSTN).

Non-resident businesses supplying digital services to consumers in Singapore, Australia or New Zealand are required to register for GST regardless of local physical presence — triggered by the overseas vendor registration (OVR) rules in each jurisdiction.

How It Works

From Application to
Tax ID Issued — Step by Step

1

Consultation — Which Tax IDs Does Your Company Need?

Not every company needs every tax ID — it depends on jurisdiction, business activity, turnover, whether you have employees and your personal tax residency. CompanyVista advises specifically on which IDs are mandatory immediately, which can wait and which are triggered by crossing a turnover threshold. Free, no commitment. For ITIN, we also assess whether your circumstances genuinely create a US tax filing obligation before advising you to apply.

⏱ Free consultation — included with company formation or standalone
2

Written Quote — Professional Fee Confirmed

All government tax IDs are issued free of charge by the relevant authority — there is no government fee for EIN, ITIN, VAT, GST or any other ID listed. CompanyVista's professional fee covers preparation, submission, IRS/authority liaison and follow-up — confirmed in a written quote before any payment. Tax ID registrations can be standalone or bundled with company formation.

⏱ Written quote within 4 hours
3

Document Collection & Preparation

CompanyVista collects all required documents and prepares the application to the authority's exact requirements. For EIN (Form SS-4): company details, responsible party information, business purpose. For ITIN (Form W-7 via CAA): identity verification conducted by our CAA — original passport remains with you. For VAT/GST: company registration documents, director details, business activity description, estimated turnover.

⏱ 1–3 business days — minimal input required from you
4

Submission to the Relevant Authority

EIN: SS-4 submitted to the IRS via fax (4–6 weeks) or via the IRS Business & Specialty Tax Line — a process that involves long IRS hold times and typically results in EIN assignment within 5–10 business days of the call, with the CP575 confirmation letter arriving by post 3–4 weeks later. For C-Corporations where CompanyVista acts as responsible party, expedited EIN issuance within 1–3 business days is available. ITIN: W-7 with CAA certification submitted to the IRS Austin Service Centre. VAT: submitted to HMRC (UK), FTA (UAE) or the relevant EU authority online. GST: submitted to IRAS (Singapore), ATO (Australia), CRA (Canada) or relevant authority. CompanyVista tracks every submission to receipt confirmation.

⏱ Submitted same day documents are received and verified — processing times vary by authority and method
5

Authority Processing & Proactive Updates

Processing times vary by authority and ID type. CompanyVista monitors status proactively and contacts the authority to follow up where processing exceeds standard timelines. For EIN by fax: 4–6 weeks total. For EIN by phone: assignment typically within 5–10 business days of the call; CP575 letter by post 3–4 weeks after assignment. For C-Corp expedited: 1–3 business days where CompanyVista is responsible party. For ITIN: 7–11 weeks — we check status and notify you immediately on issuance. For VAT/GST: typically 2–5 weeks — we notify on registration number issuance and provide a copy of the registration certificate.

⏱ EIN fax: 4–6 weeks · EIN phone: 5–10 days assignment + 3–4 weeks CP575 · EIN C-Corp expedited: 1–3 days · ITIN: 7–11 weeks · VAT/GST: 2–5 weeks

For VAT: VAT registration certificate and VAT number. For GST: GST registration certificate and GST number. CompanyVista also advises on the next compliance obligations triggered by registration — VAT return filing dates, GST filing frequency, quarterly submission deadlines.

  • You plan to hire any US-based employees or contractors
  • You need to file any US federal or state tax return

💡
Not sure which IDs you need? During your free consultation, CompanyVista advises exactly which tax IDs are mandatory for your company immediately, which are triggered by turnover thresholds and which you should apply for proactively. We do not recommend registrations that are not needed — unnecessary VAT registration, for example, creates a filing obligation without benefit.
Why CompanyVista

Why Choose CompanyVista
for Tax ID Registration?

🎓

IRS CAA — Passport Stays With You

CompanyVista's founder is an IRS Certified Acceptance Agent — one of fewer than 5,000 globally. ITIN applicants using the CAA pathway do not surrender their original passport to the IRS. Documents are verified and certified by our CAA. This is the single most important advantage for international clients applying for an ITIN.

📞

EIN for Non-Residents — We Handle the IRS

Non-residents cannot use the IRS online EIN portal — it requires a US Social Security Number. CompanyVista handles the SS-4 preparation and IRS submission entirely. The IRS phone line involves very long hold times and EIN assignment takes 5–10 business days after the call, with CP575 arriving by post 3–4 weeks later. For C-Corporations, an expedited 1–3 business day route is available where CompanyVista acts as responsible party. You never need to contact the IRS yourself — we manage it entirely.

🌍

All Tax IDs — One Team, 50+ Countries

EIN, ITIN, UK VAT, UAE VAT, EU VAT, Singapore GST, Australian GST, Canadian GST/HST, New Zealand GST, India GSTN — all handled by the same CompanyVista team that registered your company. No handoffs to a local agent in each country. Same client portal, same account manager, same process.

💡

We Advise — Not Just Execute

CompanyVista advises on which IDs are actually necessary before executing any registration. Unnecessary VAT registration creates a quarterly filing obligation. Premature ITIN application is rejected. We assess your specific situation and recommend only what your company genuinely needs — at the right time.

📋

Government Fees — All Free

Every government authority issues tax IDs at zero cost — EIN, ITIN, VAT, GST, UTR, UEN, ABN, BN — all free from the government. CompanyVista's professional fee covers preparation, submission, authority liaison and follow-up. No hidden government fees added to your invoice — because there are none.

📅

Compliance Reminders — After Registration

Every tax registration triggers ongoing filing obligations — UK VAT returns quarterly, Singapore GST returns quarterly, US tax return annually. CompanyVista adds every filing deadline to your compliance calendar on the day of registration and sends proactive reminders before each due date. Registration is just the start — we track what comes next.

Frequently Asked Questions

Tax IDs & Registrations —
Questions Answered

Can a non-resident apply for an EIN for a US LLC? +
Yes — non-residents can and must obtain an EIN for any US LLC or corporation. However, non-residents cannot use the IRS online EIN portal, which is restricted to applicants with a US Social Security Number (SSN). Non-resident EIN applications must be made via IRS Form SS-4 submitted by fax (4–6 weeks processing) or by calling the IRS Business & Specialty Tax Line — involving long hold times with EIN assignment 5–10 business days after the call and CP575 by post 3–4 weeks later. CompanyVista handles the complete process — SS-4 preparation, fax submission or IRS phone call — entirely on your behalf.
What is a Certified Acceptance Agent (CAA) and why does it matter? +
A Certified Acceptance Agent is an individual or entity authorised by the IRS to verify original identity documents on behalf of ITIN applicants. In the standard ITIN process, applicants must send their original passport to the IRS Austin Service Centre for verification — where it remains for the entire 7–11 week processing period, during which the applicant cannot use that passport for international travel. The CAA pathway avoids this entirely: our CAA verifies your original documents and submits certified copies to the IRS. Your passport never leaves your possession. CompanyVista's founder holds IRS CAA status — a significant advantage for international clients.
Does every US LLC owner need an ITIN? +
No — not every US LLC owner needs an ITIN. An ITIN is required only if you have a US tax filing obligation as an individual. This typically applies to non-US residents who: receive US-source income subject to US withholding tax (royalties, dividends, US real estate income), must file a US non-resident tax return (Form 1040-NR), or need to complete a W-8BEN for a US payer. A single-member LLC with no US-source income and a non-resident owner generally has no ITIN requirement. CompanyVista advises on whether your specific situation creates an ITIN requirement before recommending an application.
When must I register for VAT in the UK? +
UK VAT registration is mandatory when your taxable turnover exceeds GBP 90,000 in any rolling 12-month period — you must register within 30 days of breaching the threshold. Voluntary registration below the threshold is also available and often beneficial — it allows you to reclaim VAT on UK business purchases and can signal credibility with UK clients. Non-UK businesses supplying taxable goods or services in the UK must register regardless of turnover — there is no registration threshold exemption for non-UK established businesses in many supply categories.
Does registering for VAT or GST mean I have to charge tax on all invoices immediately? +
Yes — from the effective date of VAT/GST registration, you must charge the applicable rate on all taxable supplies. For UK VAT: 20% standard rate (or 5%/0% for reduced/zero-rated supplies). For UAE VAT: 5%. For Singapore GST: 9%. You must also issue VAT/GST-compliant invoices, maintain digital records and file periodic returns. CompanyVista advises on compliance obligations triggered by each registration and can manage ongoing VAT/GST return filing as part of our compliance and accounting service.
How long does EIN processing take for non-residents? +
Via fax (IRS Form SS-4): 4–6 weeks total from submission — the IRS processes fax submissions in order of receipt and mails the CP575 confirmation letter to the address on the SS-4. Via IRS Business & Specialty Tax Line (phone): IRS hold times are typically very long — often several hours. EIN assignment following the call takes 5–10 business days, with the CP575 confirmation letter arriving by post a further 3–4 weeks after assignment. The phone method is not a same-day solution and involves significant IRS wait times — CompanyVista manages the entire process on your behalf. Expedited option: For US C-Corporations where CompanyVista acts as the responsible party on the SS-4, EIN assignment can be obtained within 1–3 business days. This route is exclusively available for C-Corps — contact us to confirm eligibility.
Can CompanyVista handle tax ID registrations for companies formed by another provider? +
Yes — tax ID registration is available as a standalone service for companies formed by any provider. CompanyVista requires the company's formation documents (Certificate of Incorporation, operating agreement, M&A) and director/UBO details. There is no requirement that CompanyVista formed your company to assist with EIN, ITIN, VAT, GST or any other tax registration. Contact us with your company details for a free consultation and written quote.
What is the difference between EIN and ITIN? +
An EIN (Employer Identification Number) is a tax ID for a business entity — your LLC, corporation or partnership. Every US business entity needs an EIN. An ITIN (Individual Taxpayer Identification Number) is a tax ID for an individual who has a US tax filing obligation but no SSN — typically a non-US resident individual who receives US-source income or must file a US tax return. Your LLC needs an EIN. You as an individual may or may not need an ITIN — depending on whether you personally have a US tax filing obligation. They are not interchangeable and one does not substitute for the other.
Is there a government fee for EIN, ITIN or VAT/GST registration? +
No — all government tax IDs are issued free of charge by the relevant authority. The IRS charges no fee for EIN or ITIN applications. HMRC charges no fee for UK VAT registration. The UAE FTA charges no fee for VAT registration. IRAS charges no fee for Singapore GST registration. The ATO charges no fee for Australian GST/ABN registration. CompanyVista's professional fee covers preparation, submission, authority liaison and follow-up — the government itself charges nothing.
Do I need to register for GST in Singapore or Australia if I am a non-resident selling digital services? +
Yes — both Singapore and Australia apply Overseas Vendor Registration (OVR) rules that require non-resident businesses to register for GST/GST if they supply digital services to local consumers above specified thresholds, regardless of whether they have any physical presence in the country. Singapore OVR threshold: SGD 100,000 of B2C digital services. Australia OVR threshold: AUD 75,000 of taxable supplies. New Zealand applies similar rules. CompanyVista handles OVR registration for non-resident digital service providers in all three jurisdictions.

EIN, ITIN, VAT & GST Registration Services — Complete 2025 Guide

CompanyVista provides professional tax ID registration services for companies in 50+ countries — EIN (Employer Identification Number) for US LLCs and corporations, ITIN (Individual Taxpayer Identification Number) via the IRS Certified Acceptance Agent (CAA) pathway, VAT registration in the UK (HMRC), UAE (Federal Tax Authority) and all 27 EU member states, and GST registration in Singapore (IRAS), Australia (ATO), Canada (CRA), New Zealand (IRD) and India (GSTN). All government tax IDs are issued free of charge by the relevant authority — there is no government fee for any registration. CompanyVista's professional fee covers preparation, submission, authority liaison and follow-up.

Two key advantages distinguish CompanyVista in this service: First, non-resident EIN applicants cannot use the IRS online portal (restricted to SSN holders) — CompanyVista handles the full IRS Form SS-4 preparation and submission via fax or direct IRS phone call, including speaking with IRS personnel on your behalf. Second, CompanyVista's founder holds IRS Certified Acceptance Agent (CAA) status — one of fewer than 5,000 globally — which allows ITIN applicants to retain their original passport throughout the 7–11 week processing period, with certified copies submitted to the IRS instead of originals. For international clients who travel frequently, this is a critical advantage over the standard pathway.

Tax ID registration is available as a standalone service or bundled with company formation. VAT and GST registration triggers ongoing quarterly filing obligations — CompanyVista's compliance and accounting service manages all return filing after registration. All tax ID registrations include a compliance calendar update with every filing deadline from the day of registration. CompanyVista advises on which registrations are actually necessary before executing any application — unnecessary VAT registration creates a quarterly filing burden without benefit, and premature ITIN applications are rejected by the IRS.
