S Corp Tax Calculator

An S corp is one of several entities, including partnerships and sole proprietorships, that business owners can choose to form. While S corps and C corps may sound similar, they are taxed very differently. Unlike C corporations, which feature double taxation, S corps are pass-through entities and typically avoid paying federal income tax. With S corps and other pass-through entities, profits and losses are passed through to the owners, who then report them on their personal tax returns.

While S corps and limited liability companies (LLCs) are both pass-through entities, there are distinct differences. LLCs have no eligibility requirements, while S corp owners must adhere to specific rules to maintain this status. LLCs also have flexibility in profit distribution that S corps don't, although S corp owners can usually avoid paying the 15.3% self-employment income tax (effectively Social Security and Medicare taxes on self-employment income) while LLC owners can't. LLC owners can, however, deduct half of what they pay in self-employment tax.

If you're considering forming your business as an S corp, be aware of the numerous tax advantages this entity type provides, including pass-through taxation, a lack of self-employment tax obligations, and the ability to claim numerous deductions, including the 20% qualified business deduction. If your business meets IRS eligibility criteria, make your entity selection official to begin experiencing the tax advantages of operating as an S corp.

S corps, like other business entities, are responsible for filing taxes throughout the year, not just in April. S corps must file IRS Form 1120-S, U.S. Income Tax Return for an S Corporation, along with Schedule K-1, by March 15. S corp owners, called shareholders, will report business profits and losses on their personal income tax returns, due on April 15. Quarterly estimated taxes are also due on April 15, June 15, September 15, and January 15. Adhering to each deadline will help your S corp maintain compliance.

If you've just formed your business as an LLC, you have great flexibility during the first 75 days of operation to select a different entity, including an S corp. While the tax benefits of operating as either entity can overlap, both feature pass-through taxation—you should select the most advantageous business structure for your tax situation. Review S corp eligibility requirements and submit IRS Form 2553, Election by a Small Business Corporation, to officially make the switch.

While the best time for your business to elect S corp status may differ from other businesses, certain times are more optimal than others. Electing S corp status may be advantageous at the start of the tax year (many businesses follow the calendar), when your business is being officially formed, after the results of a tax savings analysis, or to adhere to state S corp requirements, which can vary throughout the year.

Unlike other entities, which may have few barriers to operation, S corp owners must adhere to several eligibility requirements to qualify and maintain their status. The added responsibilities these requirements impose are viewed as a downside by some business owners who have formed other entities. To be eligible for S corp status, your business must be a domestic corporation, you must only have allowable shareholders, your business must have 100 shareholders or fewer and only one class of stock, and your business cannot be an ineligible corporation.
