For a US LLC, a business plan should be a practical instrument that lays out your entity and tax structure, how you will set up banking, and the 12- to 24-month cash runway. It is not simply a narrative for a pitch. The first 90 days of an LLC’s life are when planning is critical; this is the time founders are making calls on bookkeeping, state compliance, and EIN filing, and those are decisions you do not want to have to put right at great cost down the line.
There is a tendency among founders to view business planning as an exercise in putting together a document for investors. In practice, especially for non-resident and first-time founders, that is seldom the issue. The trouble comes from making the wrong calls or forgoing them altogether. By the sixth month, you can find an LLC with a registered agent notice that has been ignored, an unopened bank account, and a tax election that no longer makes sense.
Across LLCs founded by founders from more than 175 countries, the plans that stand the test of time have something in common: they are a series of operational moves made to meet real deadlines, not static files to be put in a drawer.
What Should a Business Plan Actually Include for a New LLC?
Forget the 40-page template. A plan that works has six parts, each one corresponding to a decision on the table in year one:
- Your choice of entity and state, and why.
- Tax classification, be it a default LLC, S-corp, or C-corp conversion.
- The sequence for the EIN and banking, down to the documents the bank will ask for.
- An annual report calendar and registered agent for the state of formation.
- A 12-month cash flow separating variable operating from fixed compliance costs.
- Triggers to put the plan back in front of you, such as hitting $600k in revenue or opening a second state.
Some founders will put in three weeks on market analysis but take no time to discover their home country lacks a tax treaty with the US, which completely alters their withholding on Form 1042-S. Length is less important than order. Just as someone researching IT Diploma Courses Online needs to understand accreditation, costs, and career outcomes before enrolling, LLC founders need to evaluate tax and compliance implications before making structural decisions.
When Should You Write the Plan: Before or After Forming the LLC?
Get a first draft done before you file your Articles of Organization. It’s worth having the state and entity type settled at that point, then treating the rest as a living document to be revised every month over the first two quarters.
It is a matter of practicality. Take Wyoming and Delaware as of August 2026: forming an LLC is $60 and $110, respectively. But Wyoming’s annual report is $60, and there is no state income tax, whereas Delaware will levy a $300 franchise tax come what may. You would be wise to have your cash flow plan in place before picking a state; otherwise, you may be building around one that does not suit your margins.
Take a 2025 case in point. A founder put his company in Delaware on the strength of some general counsel, only to find during his business planning that the $300 franchise tax was hard to justify for a pre-revenue SaaS tool with no US investors in the wings. By the time he decided to re-form in Wyoming, the dissolution and re-formation fees had him paying more up front than a proper state comparison would have warranted.
What Filing Fees and Timelines Should Be in Your Financial Plan?
It has to be built on real numbers, not the kind of ranges one might find in an old 2019 blog post. The following is what non-resident founders are putting down as of August 2026.
| Item | Typical Cost | Processing Time |
| LLC formation (state fee, varies) | $50 to $500 | 1 to 3 weeks standard, 24-48 hrs expedited in most states |
| EIN application (IRS, no SSN/ITIN) | $0 direct to IRS | 4 to 8 weeks by fax or mail as a non-resident |
| Registered agent (annual) | $100 to $300/year | Ongoing |
| Annual report / franchise tax | $0 to $800 depending on state | Due annually or biennially by state |
| Form 5472 + 1120 (foreign-owned single-member LLC) | Preparation cost varies | Due April 15, extendable to October 15 |
You will find that the EIN is where most founders get tripped up. Without an SSN or ITIN, the IRS online portal is off-limits. You are left to file Form SS-4 by mail or fax. For much of 2026, the IRS is taking 4 to 8 weeks to process non-resident applications, and longer if there is a backlog in March or April. Make sure you schedule your first client contracts and bank account opening with that in mind, rather than the 15-minute affair a US resident enjoys.
What Mistakes Do Founders Make in Their Business Plans?
For one, they make the EIN a formality when it is, in fact, a dependency. Your payment processor and B2B contracts will wait on it. A plan that does not factor in the non-resident timeline gives you a false impression of readiness.
Then there is the matter of Form 5472. If you run a foreign-owned single-member LLC, you must file this with a pro forma 1120 even if you have not made a dollar. The penalty for oversight is $25,000 to start. It is not something people put in their budget, and it has a way of being a shock come March.
Some will pick a state based on formation cost alone. The $60 to file in Wyoming seems like a good deal until you have to register as a foreign entity in the state where you are actually working, which can result in two sets of annual fees.
Compliance costs also need to be ring-fenced from growth expenditures. You cannot skip registered agent or tax prep fees without legal repercussions, so they should be on a separate line from marketing or headcount.
Finally, too many founders draw up five-year projections for a business with no revenue to speak of, all based on assumptions that are difficult to defend. An 18-month plan with actual filing deadlines is far more useful.
How Should Non-Resident Founders Adjust Their Business Plan?
For a founder setting up a US LLC from abroad, the standard template won’t do. Your plan has to account for two things most domestic founders don’t have to worry about.
Start with a banking access plan. You won’t be able to simply walk into a branch in the US. While there are services like Mercury or Wise that will open an account for a foreign-owned LLC remotely, they all have their own document requirements and ways of rejecting an application. Allow yourself a buffer of two to four weeks to complete this and put a backup in place in case your initial application is sent for manual review.
Then you need to do a tax treaty check. A quick 30-minute look at the IRS treaty table can prevent months of head-scratching down the road. The presence or absence of a treaty between the US and your home country will determine your withholding obligations and your approach to obtaining an ITIN. In some cases, it even informs whether you should be a C-corp or a disregarded LLC.
Do not be caught off guard by state compliance either. It is more variable than one might think. Take California: if you are “doing business” there under their broad interpretation, the $800 franchise tax is due every year for an LLC, no matter how active you are or where you are physically located. New York has its own quirks; certain counties require you to go through an LLC publication process, with costs ranging from $200 to $2,000 depending on local newspaper rates. These are not edge cases but standard line items for anyone operating in those states.
FAQs
Is a formal business plan a requirement for an LLC? The state will not ask for one when you file Articles of Organization. But you will want to have at least a lean version on hand for any talk with an investor, a lender, or for visa purposes.
What is the right length for a small LLC? Eight to twelve pages will suffice for most single or small multi-member operations. Cover the structure, the tax and cash flow plans, and your compliance calendar. There is no virtue in padding the page count.
Can I make changes once the LLC is formed? You should. For the first couple of quarters, consider it a working document as you deal with your EIN, banking, and the first round of tax deadlines.
Where do non-resident founders tend to go wrong? They don’t give enough time to the EIN process. Lacking an SSN or ITIN means a 4- to 8-week wait via fax or mail, which throws a wrench in the whole launch sequence.
