Do LLCs pay taxes in Illinois?
Yes, LLCs are a “pass-through” tax entity. This means that the LLCs profits are “passed through” directly to its owner(s), who then pay income taxes independently.
This is advantageous compared to a corporation’s tax structure because it means that LLC members are not taxed twice.
Having said that, readers should keep in mind that LLCs are very flexible when it comes to how they can be taxed, and — depending on the specifics — they can choose to be taxed as a pass-through entity, a C corp, and an S corp.
For more information, see our How Is an LLC Taxed guide.
What are the tax benefits of an LLC?
The tax benefits of an LLC will depend on how you choose to be taxed, as well as on whether you are operating as a single or multi-member LLC.
Generally speaking, LLCs can choose to be taxed in several different ways, including:
- As a sole proprietorship or general partnership
- As a C corporation
- As an S corporation
See our Single-Member LLC Taxes guide for a detailed overview of the tax benefits of having an LLC as a small business.
Do I need to open a business bank account for my LLC?
Even though you do not necessarily “need” to open a bank account for your LLC, this is generally highly recommended for several reasons.
For one, having a separate bank account can allow you to maintain your LLC’s corporate veil — meaning that you will not risk losing your limited personal liability under the law. A business bank account also offers financial benefits, including the ability to build business credit more quickly and access to larger business loans.
