Frequently Asked Questions

Should I choose S corp for my LLC?

S corp status isn’t right for every business. If you're unsure whether to elect S corp status for your LLC or stick with its default setup, it’s best to speak with a business attorney or accountant in your state who can guide you based on your specific situation. You can also decide to change to an S corp down the road.

Can I change my LLC to an S corp?

Yes, you can. Your company will continue to operate as an LLC business structure, but it can be taxed as an S corp. You should consider the S corp tax structure if you expect to earn substantial profits (beyond reasonable salary), if you want to save on self-employment taxes, or if you plan to work actively in the business and you’re a U.S. citizen or resident.

When should I NOT choose an S Corp?

You want foreign owners or investors, you plan to retain earnings in the company (S corps must pass all profits through to owners), you have multiple classes of ownership or profit-sharing, you don’t want to deal with payroll and compliance paperwork, you're not making enough profit to justify the extra compliance burden.

How do I elect S corporation tax status for my existing LLC?

To change from an LLC to an S corp, you don't need to form a new company. You simply elect to be taxed as an S corp, and you can make this election for your LLC later as well.

S Corporation benefits

S corporations are generally designed for smaller business entities. It works very similar to an LLC in protecting your personal assets, but you are able to pay yourself a salary from the company. Owners pay personal income tax on the profits and business income and loss is passed to the owners on tax returns. There can be no more than 100 shareholders so the entity will stay on the smaller side and have different management structure than a C corporation. Shareholders must also be US citizens or resident aliens.

Key benefits of an S corp:

  • Personal Asset Protection: Keep your personal finances separate from your business’s liabilities.
  • Pass-Through Taxation: Avoid double taxation by passing profits and losses directly to your personal tax return.
  • Lower Self-Employment Tax: Save on payroll taxes (FICA) compared to a standard LLC or sole proprietorship.
  • Perpetual Existence: An S-Corp continues to exist even if the owner changes, offering stability for the business.
  • Flexible Accounting: Choose the best accounting method to fit your business needs.
  • Easy Ownership Transfer: Transferring shares of an S-Corp is straightforward, providing flexibility for future growth.
  • Enhanced Credibility: Being an S-Corp can boost your business’s professional image and attract potential investors.

C Corporation benefits

C corporation is great for businesses that sell products, have a storefront or have employees. If you ever want to go public in the future, this is the entity you should consider in order to have unlimited shareholders. Tax implications are key in choosing this entity. Businesses must pay a corporate income tax, and dividends are distributed at the individual level. Owners pay personal income tax on profits and healthcare premiums for your employees can be written off.

Why use online business formation services to when setting up an S corporation?

These filing services and industry experts offer all the services you would need to start and run your business, such as preparation and filing of LLCs and corporations, business licenses, legal documents, compliance and registered agent services, all in one place for an affordable price.

Why should I be setting up an S corporation?

On top of the benefits we already mentioned , S corporations have a certain level of prestige and credibility. Your customers might trust you more with an Inc or LLC after your name. Banks might more easily lend money according to your business structure as well.

All the services on our top charts support both the S corporation structure and  the LLC (Limited Liability Company) structure  and can advice on the right structure for you based on your specific needs.

Additional S corp & Business services

Do I need to appoint a registered agent?

Yes, in most states, appointing a registered agent is mandatory. We highly recommend using a professional registered agent service. All brands listed on our charts offer professional registered agent services.

BOIR for business

Starting in 2024, new and existing U.S. businesses should submit the ‘Beneficial Ownership Information Report’ (BOIR) to FinCEN. This report includes personal information about key individuals in the company including the entity, its beneficial owners, and in some cases its company applicants. The top LLC filing services listed on our chart can help you with the BOIR requirement.

Business license

Many businesses might require licenses or permits. The license and permits requirements will depend on the type of business as well as the state in which you incorporate your business. Professional business formation services can help you obtain a business license in all 50 states and assist with submitting your BOIR.
