Filing the paperwork feels like the finish line. You submit your articles of organisation, pay the state fee, and wait. But that moment is actually the starting point, not the end. A lot of founders get caught off guard by everything that comes next — from tax registrations to banking to operating agreements. Here’s what to expect once your LLC is officially on record.
Your First Week: What Arrives and What You Do With It
One useful step at this stage, especially if you haven’t already sorted your business infrastructure, is to use a resource like a free LLC starter kit. These often bundle essentials like a business domain, professional email address, and website tools — things that would otherwise take several separate sign-ups to sort. Getting these in place early saves time when you start promoting your business.
Once the state approves your filing, you’ll receive confirmation — usually a stamped copy of your articles or a certificate of formation. This document proves your LLC legally exists. Keep it somewhere safe because you’ll need it repeatedly: when opening a business bank account, applying for licences, and sometimes when working with clients or suppliers.
Getting Your EIN
An employer identification number (EIN) is the federal tax ID for your LLC. Even if you don’t plan to hire anyone, you’ll need one to open a business bank account in most cases. The IRS issues EINs for free, and the online application takes about ten minutes if you’re a US-registered business.
For UK founders setting up a US LLC — a common move for access to global payment processors — the process is slightly different. You’d apply by fax or post since international applicants can’t use the online portal. It takes longer, so factor that in before you need the account to actually function.
The Operating Agreement: Often Overlooked, Rarely Unimportant
Many states don’t legally require an operating agreement, which leads a lot of founders to skip it entirely. That’s a mistake. The operating agreement sets out how the LLC runs — who owns what percentage, how decisions get made, how profits are distributed, and what happens if someone wants to leave.
Without one, disputes between members get messy fast. Even if you’re the sole owner, having a written operating agreement reinforces the separation between you and the business. That separation matters for liability purposes.
A basic operating agreement should cover:
- Ownership percentages and member roles
- How profits and losses are allocated
- Voting rights and the decision-making process
- What happens if a member exits or the LLC dissolves
- Rules around adding new members.
You can draft a simple one yourself using free templates or get a solicitor to prepare something more robust if the structure is complicated.
Licences, Permits, and Local Requirements
Your LLC being registered doesn’t automatically mean you’re authorised to operate. Depending on your industry and location, you may need additional licences or permits at the state, county, or municipal level.
A food business, for instance, needs health permits. A financial services company will need industry-specific licences. Even a simple consultancy might need a local business licence from the city or county where it operates.
Separate Bank Account — Non-Negotiable
This comes up in every guide for a reason: using your personal account for business transactions is one of the fastest ways to lose the liability protection an LLC provides. Courts can “pierce the corporate veil” — meaning they can hold you personally responsible for business debts — if the finances are mixed together.
Open a dedicated business bank account as soon as you have your EIN and formation documents. Some founders also get a business credit card at this stage to start building a credit history for the entity.
Taxes: What Changes After Formation
An LLC doesn’t have a default federal tax structure of its own in the US. By default, a single-member LLC gets taxed as a sole proprietorship (income flows to your personal return), while a multi-member LLC gets taxed as a partnership.
You can elect to change this. Some LLCs file to be taxed as an S-corp, which can reduce self-employment tax once income reaches a certain level. It’s worth speaking to a tax professional before making that call — the savings can be real, but so can the additional administrative requirements.
| Tax classification | Who it suits | Key consideration |
| Disregarded entity (default, single-member) | Solo founders in early stages | Simple, no separate business return |
| Partnership (default, multi-member) | Early-stage multi-founder LLCs | Each partner reports their share |
| S-corp election | Profitable LLCs, typically $50k+ net | Reduces self-employment tax |
Annual Compliance: What Keeps Your LLC Active
Most states require LLCs to file an annual report and pay a small fee to stay in good standing. Miss it, and the state can administratively dissolve your LLC, which creates a headache to fix. Set a calendar reminder for your state’s filing deadline.
Some states, like California, also charge an annual franchise tax regardless of whether the business made money. Know what your state requires before the first year is up.
