Tax Registration in United States
The federal EIN on Form SS-4 — which you need to open a US bank account and to file anything — plus the state registrations that genuinely apply to you. State registration is NOT one national process: there is no federal sales tax and no federal VAT, and registration, rates, economic-nexus thresholds and filing cadence differ by state and often by locality. Delaware itself levies no sales tax. Forming in Delaware does not exempt you from registering and paying tax in the state where you actually operate, so we scope your nexus state by state rather than quoting a national figure.

Responsible party details for Form SS-4
An SSN or ITIN lets the responsible party apply online; without one the application goes by fax or mail. The current IRS process and timeline for that route is unverified in our research and is confirmed on irs.gov before we commit to a date.
States where you have employees, an office, inventory or revenue
Drives which state registrations are actually required. Economic-nexus thresholds are commonly reported at around $100,000 in sales or 200 transactions a year, but they vary by state and were not verified in our research.
Intended federal tax classification
Default pass-through, or a Form 8832 election to be taxed as a C-corporation, or a Form 2553 S-election where eligible.
Cost breakdown
Our fee and the government’s are always separate lines. Government fees are passed through at exactly what the authority charges — we add nothing to them.
| IRS EIN (Form SS-4)No published IRS charge for EIN issuance was captured in our 10 September 2026 research, so no amount — including zero — is asserted. Confirmed on irs.gov at quote. | Confirmed before payment |
| State tax registrations (per state)Deliberately not a national figure. Sales-and-use tax registration, rates, nexus thresholds, filing cadence and e-filing all differ by state and often by locality, and none of it was verified in our research. There is NO federal sales tax and NO federal VAT; Delaware levies no sales tax. Quoted per state once your nexus is scoped. | Confirmed before payment |
