01

Month 1: Essentials

EIN obtained (same-day for US founders; 1-3 weeks for foreign). Business bank account opened. Founder stock issuance with signed Stock Purchase Agreements. 83(b) elections filed within 30 days (critical - missing this is a six-figure mistake). Bylaws (corp) or Operating Agreement (LLC) adopted. BOI filing to FinCEN within 30 days. Initial corporate resolutions adopted at first board/member meeting.

02

Month 2-3: Operations Foundation

State business registrations (sales tax permit, employer registrations if hiring). IP assignment agreements for founders. Initial contracts in place: NDA, customer template MSA, vendor templates. Books and accounting set up (Quickbooks Online, Xero, or our books service). Compliance tracking initiated.

03

Month 4-6: First Hire / First Customer Phase

First employee or contractor (if applicable): payroll service setup, workers comp insurance, employment agreements, IP assignment. First major customer contracts using template MSA. State tax registrations in nexus states.

04

Month 6-9: Mid-Year Review

Books reconciliation: are revenue and expenses accurately categorized? Cap table review: are option grants up to date? Compliance review: are state registrations current? Compliance check on BOI and any quarterly filings (941 for employees).

05

Month 9-12: Year-End Prep

Annual report filing (state-specific timing). Tax preparation: estimated tax payment Q4 (January 15). 1099-NEC issuance to contractors (January 31). W-2 issuance to employees (January 31). State employer year-end reports.

06

Ongoing: Compliance Cadence

Quarterly: 941 employer filings (April 30, July 31, October 31, January 31). Quarterly estimated tax (April 15, June 15, September 15, January 15). Monthly: bookkeeping reconciliation, payroll, sales tax filings (if monthly). Annual: state annual report, federal and state tax returns, BOI updates.

07

Investor Readiness

Data room: incorporation documents, bylaws/OA, cap table, financial statements, customer contracts, IP assignments, employment agreements. By month 12: data room should be assembled and current.

08

Common Mistakes

Missing 83(b) deadline (30 days from grant). Skipping IP assignments from contractors. Operating without business bank account (commingling pierces the LLC veil). Failing to file annual report. Not tracking state registrations as you expand.

FAQ

Common questions.

What do I need to do after forming my company?
Formation is the start: you generally need to get your EIN, adopt an operating agreement or bylaws, open a business bank account, handle licenses and permits, set up bookkeeping, and calendar ongoing compliance, so the entity actually functions and stays protected. We flag the full checklist so nothing critical is skipped.
Why do I need an operating agreement or bylaws?
Because internal governance documents, an operating agreement for an LLC or bylaws for a corporation, set how the business is owned and run and help preserve your liability protection, even for a single owner. We flag their importance so your entity is governed properly, not just registered.
Do I need a separate bank account right away?
Yes, promptly: mixing personal and business funds is one of the fastest ways to undermine your liability shield, so opening a business account, which needs your EIN and formation documents, is an early priority. We flag this so your entity's separateness holds up from the beginning.
What licenses and permits might I need?
It varies by industry and location, general business licenses, professional or occupational licenses, sales tax permits, and local permits, so the requirements depend on what you do and where. We flag the likely categories so you are not operating without a license a regulator later asks for. See business licenses.
How do I keep my liability protection intact?
By respecting the entity: keep separate finances, maintain governance documents, sign in the company's name, keep records, and stay in good standing with the state, since ignoring these can let a court disregard the entity. We flag the practices that keep your liability shield effective over time.
What ongoing compliance should I calendar?
Typically your state's annual report, any franchise or state taxes, registered agent maintenance, license renewals, and tax filings, since these recur and missing them risks penalties or loss of good standing. We flag and calendar these so ongoing compliance does not slip after the initial excitement fades.
Do I need to worry about BOI reporting?
It depends: under FinCEN's March 2025 interim rule, US-formed entities are exempt from beneficial ownership reporting, while certain foreign entities still report, so many new US businesses have no BOI filing. We flag your current BOI status so you neither miss a required filing nor chase one you do not owe.
How soon should I handle all this?
Most items, EIN, bank account, operating agreement, licenses, deserve attention in the first weeks so the business can operate and stays protected, while ongoing compliance gets calendared for its due dates. We flag the priority order so your post-formation setup happens promptly and in a sensible sequence.
Can File.Business handle my post-formation setup?
Yes: beyond forming the entity, we obtain the EIN, provide the operating agreement and registered agent, flag licenses and permits, and calendar your ongoing compliance, so your business is fully set up and protected rather than just registered and left to figure out the rest.

How it works

How we deliver, end-to-end.

Four-step path from request to confirmation. State and IRS turnaround varies; our steps run in parallel where possible to compress the timeline.

1

Intake + scope

You tell us what you need through a short intake form (or a call for complex matters). We confirm scope, surface any gating issues (deadlines, missing documents, entity status), and quote any state fees that pass through at cost.

2

Prepare + verify

Our specialists draft the filing, verify entity details against state databases, run internal QA, and route any items needing your sign-off. You see drafts before anything gets submitted.

3

File with the authority

We submit directly to the state Secretary of State, FinCEN, IRS, USPTO, or whichever authority your filing requires. We pay state fees at cost and track the submission identifier in your account.

4

Confirmation + vault

Stamped certificate, IRS notice, or filing receipt arrives in your SOC 2 encrypted document vault the moment we receive it. Next filing deadline auto-added to your compliance calendar where applicable.
