What Happens After You File: the First 30 Days Checklist

Once the state approves your formation document, the entity legally exists, but that's a narrower fact than it feels like. It doesn't automatically come with a bank account, a tax ID, an internal governing document, or any licenses the business's actual activity might require. Those are all separate steps, each handled by a different agency or institution, and none of them are triggered by the formation filing itself. The sequence below roughly reflects the order most owners actually need to move through, though a few steps can run in parallel.

Why the order matters

Several of these steps depend on the one before it — the bank wants an EIN before it'll open an account, and some licensing applications want a bank account or an EIN before they'll process a request. Working through them out of order doesn't just waste time; it can mean submitting an application twice because the first attempt was missing something the previous step would have provided.

This is almost always the first practical step after formation, because so much else depends on it — the bank account, tax filings, and often licensing applications all ask for it. This guide to getting an EIN covers how to apply directly with the IRS at no cost, typically the same session for most applicants. Apply only after your formation is fully approved, not before — the IRS matches the application to your legal entity name and formation details, and applying too early risks a mismatch that has to be corrected later.

With your EIN and approved formation document in hand, open a dedicated business account before any real money moves through the business. This guide walks through what banks typically require — the formation document, the EIN, identification for signers, and often a banking resolution authorizing who can act on the account. Skipping this step, or delaying it while running early transactions through a personal account, is one of the most common early mistakes, because commingled funds are exactly the kind of thing that can undermine the liability shield the entity was formed to provide.

Once the bank account is open, it's worth setting up even a simple bookkeeping system — a spreadsheet, a basic accounting tool, or a bookkeeper if the volume justifies it — before the first month of transactions accumulates with no system behind them. Sorting out three months of mixed business activity after the fact is a genuinely tedious task that a little upfront structure avoids entirely.

This is also where separating funds pays off

A dedicated business account only protects the liability separation an LLC is supposed to provide if the records behind it are also clean. Consistent bookkeeping from day one is what turns "we have a business account" into a defensible, well-documented separation between the entity and its owner — the difference that matters if the shield is ever tested.

An operating agreement (or bylaws, for a corporation) usually isn't required to be filed with the state, which makes it easy to treat as optional. It isn't, in practice — this guide covers what these documents actually need to address, and why even a single-owner entity benefits from having one in writing. This is the document a bank may ask for as part of your account authorization, and it's the document that fills in every question your formation filing didn't answer: who decides what, how profits move, what happens if an owner wants out. Doing it early, before there's any actual disagreement to resolve, is dramatically easier than doing it later.

This is the step most new owners don't realize is separate from formation at all. Registering your entity with the state has nothing to do with whether your specific business activity requires a license or permit — those are entirely different government relationships, layered across state, county, city, and industry. This guide walks through how to think about that layered requirement and how to figure out what actually applies to your specific business. Even if nothing turns out to be required, it's worth actively checking rather than assuming formation covered it.

Every entity owes some form of recurring compliance filing — commonly called an annual report — on a schedule that starts running from formation and repeats for as long as the entity exists. This guide explains what the filing actually involves, and this one covers what happens if it's missed — a sequence that, left unresolved, ends in the state administratively dissolving the entity. The single best time to note this deadline somewhere durable — a calendar, a compliance tracker, or a registered agent service that tracks it for you — is right now, in the first 30 days, while it's fresh, rather than trusting future-you to remember a due date that's still many months away.

Not everything on this list carries the same urgency. Roughly:

Can't really wait: the EIN (almost everything else depends on it), the business bank account (every day of commingled funds is a day of avoidable risk), and noting your annual report deadline somewhere you won't lose track of it. A basic bookkeeping habit belongs in this bucket too — it's easy to set up in the first week and considerably harder to reconstruct three months in.

Should happen soon, but has a little more room: the written operating agreement or bylaws — ideally done before any real decision needs to be made under it, but not something that breaks if it takes a few extra weeks to get right with proper input.

Worth confirming even if the answer is "nothing required": licensing and permits — this is less about urgency and more about not discovering, months in, that something was required from day one and wasn't in place.

Treating formation as the start of a short project — rather than a single event that's already finished — is what actually turns a new filing into a business that's set up to run cleanly from day one.

The pattern behind most first-year problems

Almost none of the issues that surface in an entity's first year trace back to the formation filing itself — the state's review process catches most problems with the filing before it's ever approved. What actually causes trouble later is everything around the filing that nobody was specifically responsible for tracking: an EIN that was never obtained, a bank account that never got separated from personal funds, a license that was never checked, or a compliance deadline that nobody wrote down anywhere. None of these steps are individually hard. What makes them slip is that formation doesn't come with a built-in reminder for any of them.
