FAQ
Frequently Asked Questions
- What is an EIN and why do I need one?
- An EIN (Employer Identification Number) is a US tax ID used to identify business entities. Japanese companies need an EIN to open US bank accounts, file US tax returns, or conduct business that requires US tax reporting.
- What is the default US tax classification for a Godo Kaisha (GK)?
- A Japanese Godo Kaisha (GK) is classified as a corporation by default for US tax purposes because its members have limited liability. However, a GK can file Form 8832 to elect to be treated as a disregarded entity (single-member) or partnership (multi-member), which may be advantageous for certain tax planning strategies.
- What is Form 8832?
- Form 8832 (Entity Classification Election) allows eligible entities to choose their US tax classification. Japanese Godo Kaisha can use this form to elect disregarded entity (single-member) or partnership (multi-member) treatment instead of the default corporation classification.
- How long does it take to get an EIN?
- With our 48-hour filing guarantee, we will file your EIN application with the IRS within 48 hours of engagement. IRS processing time for foreign applicants varies and is outside our control. If we fail to file within the guaranteed timeframe, you receive a full refund.
- What is the difference between a Godo Kaisha and Kabushiki Kaisha for US tax purposes?
- Both Kabushiki Kaisha (KK) and Godo Kaisha (GK) default to corporation status for US tax purposes. However, a KK is a 'per se corporation' that cannot change its classification, while a GK is an 'eligible entity' that can elect disregarded entity or partnership treatment via Form 8832.
- Do I need to visit your office in person?
- No, our EIN application service is fully remote. We handle everything electronically and communicate via email or our secure messaging platform.
