After months of hard work refining your business idea, you’re finally ready to formally create your company. It feels like a milestone — and that’s because it is. But it also marks the start of the next chapter of growth. And for Burcu Bree Manay, managing partner and CEO of Manay CPA – a company specializing in international tax, accounting, and payroll services – this moment is less about celebration and more about preparation.

“Incorporation is not the finish line,” says Bree. “The day your company is registered is the day its compliance calendar starts running.”

Choosing the right business entity and completing the initial compliance tasks are essential steps in building a business that can scale, attract investment, and avoid expensive problems down the road. Here are Bree’s recommendations on the tricky areas founders should pay attention to in order to avoid headaches down the road.

What founders need to do in the first 30 days of starting a company

As soon as you set up your entity, you are responsible for being compliant with federal, state and local laws. In some cases, there are no extensions or exceptions, and you can risk costly penalties for missing a required filing. Here are a some key tasks to complete in your first 30 days as a founder:

  1. Get your EIN. You need a federal tax ID number. Nothing else can happen without it.
  2. Sign your governing documents. These include your operating agreement or bylaws and initial board consents, plus the actual issuance of stock or stock options.
  3. File your 83(b) election within 30 days of stock issuance. There is no extension. Founders who miss this deadline can face tax on the growth in the value of their own shares.
  4. Assign intellectual property to the company. Every founder, every contractor, everyone who has ever touched the product needs to sign an agreement that the IP belongs to the company. “If your company doesn’t own its intellectual property in writing, you don’t have a company,” says Bree.
  5. Open a business bank account. Never mix personal and business funds. Even one small purchase through the wrong account can create problems later.
  6. Register where you operate. File foreign qualifications and open state tax accounts in every state where your employees are located.
  7. Set up bookkeeping. This can be as simple as a chart of accounts and a monthly bank reconciliation. You can start lean and add more later, but it is critical to build a habit of documenting everything.
  8. Handle business licenses and insurance. This is often overlooked, especially for founders entering the U.S. market. Insurance is a critical part of doing business in the U.S. and should be in place from day one.

During the first 30 days, anything with a deadline should go on a calendar that identifies when it is due and who is responsible for completing the task.

Questions founders must answer when selecting an entity type

Should you form an LLC, an S-Corporation, or a C-Corporation? The right structure for your business depends on several factors, says Bree. These include ownership, investment plans, location of operations, and more. Here are the top questions Bree likes to ask founders as they consider different entity types for their business.

Who owns the company and where do they live?

Founders can usually answer this question quickly, such as “I’m the sole founder and live in the United States” or “There are three co-founders and one of us resides outside the U.S.” However, the type of answer you give will determine what entity type you can (or cannot) explore for your business. For example, an S-Corp is unavailable if any owner is not a U.S. citizen or permanent resident. No matter how well it would otherwise fit, it’s not an option.

If your business has majority ownership outside of the U.S., you still have federal reporting obligations. And owning a U.S. company and having a personal U.S. tax obligation are two different things. Depending on the structure of your business, distributions can be subject to withholding, and you may need an individual taxpayer identification number. If a tax treaty exists between your country and the U.S., correct tax planning can prevent double taxation.

One piece of good news: You do not need to be a U.S. citizen to open a U.S. business bank account. Some bank accounts can even be opened remotely, and banks will work with foreign-owned companies that have the right documentation.

Do you plan to take any outside investments?

If the answer is yes — or even probably, at some point in the future — you’re looking at a Delaware C Corporation. For Bree, this is the right choice for Manay CPA.

“What we're really building here is an investment-ready structure,” says Bree. “And it's far cheaper to build it now than to convert later.” Converting incurs legal fees and sometimes taxes. It’s also time-consuming and can “become urgent at the worst possible moment, like in the middle of a fundraising round,” adds Bree.

Where will the business operate?

Bree says it’s a common misconception that you’re “finished” once you complete your legal formation. However, that’s never the case. You also have to register in every state where you operate, hire, or have inventory, and you are likely to need state-level or local business licenses.

What happens to the profit?

A consulting company may distribute profits to its owners every year. Another may reinvest everything for the next five years. Even if both have a pass-through structure, the outcomes are different.

In the first scenario, a founder is avoiding a second layer of taxation with an entity type such as an LLC or an S Corporation. The other is building toward qualified small business stock (QSBS) treatment in year six with a C Corporation. These are very different and reasonable approaches — but they lead to different structures.

Where do you want this business to be in five years?

Bree asks this question last and says it’s the one founders enjoy answering the most. But it’s not just small talk. Bree wants to be able to tell the difference between an owner who wants a profitable business supporting their family needs, to the one who intends to scale and sell –– as both need different structures.

For most venture-track startups, the right entity type is typically a Delaware C Corporation. “But I don’t want founders to choose it just because everybody else did,” Bree says. “I want them to understand and be able to explain why it’s the right structure for their company.”

What to keep in mind when hiring your first employee or contractor

Remote work has made multi-state hiring common for early-stage companies. But every new state where you have an employee creates obligations — and some founders don’t realize this until after they’ve made the hire.

State-specific considerations

Hiring an employee outside of the state the business operates in creates compliance requirements in the state where they are based, regardless of where the company was formed. That typically means registering with the state and setting up income tax withholding. You'll also need unemployment insurance and (in most cases) workers' compensation coverage.

U.S. employment law is very state-specific. If your team is spread across four states, you have to follow four sets of state laws. Final paycheck timing and notice practices can differ. States may even require specific policies in the employee handbook. At-will employment is the default in most of the country, but it is not a blanket permission slip.

Employee misclassification

“We’ll just pay them on a 1099” is one of the most common — and most expensive — mistakes an early-stage company can make. Bree describes employee classification as a conclusion based on how the relationship works in practice. Classification looks at who controls the worker’s schedule, whose tools are used, and how permanent the arrangement is.

If employee misclassification is found during an audit or due diligence process, the exposure is back payroll taxes plus penalties.

Common tax mistakes that cost founders money

In the 25 years Bree has been in business, she has seen founders make plenty of mistakes. Here are some that she sees most often.

  • Assuming no revenue means no filing. A U.S. company with no income can still have federal, state, and sometimes local filing obligations. The penalty for failing to file is separate from any tax owed.
  • Thinking an extension delays payment. An extension gives you more time to file, but does not give you more time to pay. Interest and penalties run from the original due date.
  • Mixing personal and business money. You weaken the liability protection of your entity and future investors can’t rely on your books.
  • Ignoring sales tax nexus. Selling products into a state past a threshold (usually $100K in sales) creates state sales tax collection obligations. If it’s discovered later, there is accumulated liability and interest.
  • Leaving benefits unclaimed. R&D credits can offset payroll taxes even with no profit. First-year equipment expensing and QSBS exclusion are available too — but only if you plan for them during the year.
  • Waiting until March to talk to your accountant. By that point, decisions that impact your prior year’s taxes have already been made.

The founders who get their taxes right and get the most benefits “are not the ones with the cleverest accountant,” says Bree, “they’re the ones who ask questions a year before everyone else.”

When to bring in professional help

There's no single revenue number that tells you when you need to hire outside help. Instead, Bree says there are a few signs for founders to look out for, including:

  • Your books are consistently more than two weeks
  • You can’t answer “How much runway do I have?” in under five minutes
  • You were surprised by your tax bill
  • You hired in another state
  • You took an outside investment (or you’re about to)
  • You're doing your books at 11pm because that's the only time you have

“That last one matters more than founders think,” says Bree. The real cost of doing your own books isn't only potential errors. It’s also that the time spent on accounting could be better spent on other parts of the business.

Hiring financial support

These are the roles you might consider hiring, and they serve different purposes.

  • A bookkeeper records what happened: categorizing transactions, reconciling books, and closing out the month. This is the first role to outsource and the least expensive.
  • A CPA decides what should happen and is accountable for the decision. A CPA is a state-licensed designation in the US. It requires exams and professional experience, and it means they can represent your company before the IRS. A CPA is trained to look more deeply at the entity structure, elections, and multi-state exposure.
  • A controller becomes necessary when you’re dealing with multiple states, complex revenue recognition, or a future audit.
  • A fractional CFO answers questions like “What should we do?” instead of reporting “What happened?” This role helps with pricing, runway scenarios, and hiring plans.

These roles don’t have to be four separate relationships. There’s real value in having bookkeeping and tax planning under one roof because they inform each other.

One final point to keep in mind: While you may delegate the work, you shouldn’t delegate your understanding of your company’s finances. In a funding round, investors ask you as the founder about the numbers — not the accountant.

Build a financial foundation from day one

Working with a professional from the beginning might seem costly, but the costs later might be much higher. U.S. laws expect all businesses to follow rules and regulations, which are often complicated and confusing.

“The cheapest hour you’ll ever spend with a CPA is the one before they incorporate,” says Bree. The setup from the beginning has a downstream impact on your business.

In her experience, the founders who come through due diligence clean have a few things in common. They have the right entity with IP assigned to the company. All of the company’s filings are current, and the books are investor-ready. “The companies we’ve supported through successful rounds have looked remarkably similar on paper,” says Bree.

That foundation is built from the beginning, not retrofitted later.
