What is IRS Form 2553?

If you’re a corporation, you may be eligible for a special business tax designation called “S corporation” (short for small business corporation or subchapter S corporation). This is a noteworthy designation because it can help reduce your corporate taxes. To become an S corporation (or S corp), you’re going to need to know all about IRS Form 2553.

Read on for our overview and the instructions to fill out form 2553.

What is IRS Form 2553?

When you file to become incorporated with the IRS (Internal Revenue Service), your business entity will be a C corporation (or C corp) by default. If you want to elect to file as an S corporation, you may file IRS form 2553 (also known as tax form 2553).

Why file form 2553 and become an S corp?

An S Corporation files form 1120S come tax season, but is not taxed on its profit (or loss). They avoid what’s called “double taxation.”

Essentially, S corporations don’t pay income taxes, rather the business owners or shareholders do on their income tax returns. Comparatively, C corporations pay a corporate tax with a tax rate of 21% in addition to what shareholders pay on their personal tax return.

S corporations are also taxed differently at the state level meaning an S corporation designation isn’t a surefire way to reduce your tax bill.

Still not sure if being an S corp is right for you? An alternative to consider is a limited liability company (LLC). Both offer similar tax benefits and liability protection.

  • You planned to file as an S corporation by the intended effective date

  • You have a reasonable cause for missing the deadline

  • All shareholders have reported their income in compliance with S corporation standards—with the business’s income split between the members—based on the corporation’s intention to elect for S corporation status and the corporation has supporting documentation to prove it
