The time is now to face the tax election deadlines for business entities. Because the March 15 deadline falls on a Sunday, the Internal Revenue Service has extended the filing deadline to Monday, March 16, 2026, under standard IRS procedures for weekend adjustments.
This extended timeline provides a narrow window for entities to implement significant tax planning strategies that can materially affect their compliance obligations and tax liability for the year.
Tax Election Deadlines for Business Entities
Why Professional Guidance Matters
Tax professionals emphasize that the decisions available during this period should not be made hastily. Each potential action carries substantial implications for an entity’s tax position and should be carefully evaluated through comprehensive tax planning analysis. Remember that a tax election for business entities has big consequences.
For entities that have not yet engaged in this analysis, many of these decisions can be implemented prospectively mid-year rather than retroactively, allowing organizations to capture tax benefits for the remainder of 2026 if immediate action is not feasible.
Filing an Extension
Entities should consider filing an extension not only to avoid late-filing penalties but also to preserve the right to file a superseding return by the unextended due date of the tax return. Even entities planning to file on time may benefit from filing an extension to maintain this flexibility.
Undoing a Prior Entity Election
An LLC that previously elected to be taxed as a corporation may revoke that election by filing a withdrawal statement with the appropriate IRS Service Center, provided this is done by the unextended due date of the entity’s first return.
This step is particularly useful when an S corporation election was made unintentionally or is no longer desired. Once the corporate classification election is withdrawn, any related S corporation election is automatically terminated. Guidance for this process appears in IRM 3.13.2.27.10.
Electing S Corporation Status (LLCs and Corporations)
To be treated as an S corporation starting January 1, 2026, an eligible entity must file Form 2553 by March 16, 2026. Many believe the S Corp is a great strategy for tax savings. However, it’s not right for everyone. There are extra complexities and compliance that come with being an S Corp, so it’s important to be aware of them.
For LLCs, a separate Form 8832 is not required. Filing Form 2553 alone is sufficient, as the corporation classification election is implied. The relevant authority includes IRC §1362(b)(1)(B) and Treas. Reg. §301.7701-3(c)(1)(v)(C).
Electing C Corporation Status
For LLCs or corporations seeking to be taxed as C corporations, filing Form 8832 by March 17, 2026, is necessary for the election to be effective on January 1, 2026. The timing for this election differs from that of S corporation elections.
Reverting to Disregarded Entity or Partnership Status
LLCs that are currently taxed as either C or S corporations may elect to return to their default classification (disregarded entity or partnership) by filing Form 8832 by March 17, 2026, for a January 1, 2026, effective date. While this action can simplify tax obligations but requires careful consideration of the implications.
No separate revocation of the S corporation election is required when this approach is used. This procedure is addressed in Treas. Reg. §301.7701-3(c)(1)(iii) and IRM 3.13.2.23.17(4) (03-08-2023).
Important limitation: If the LLC’s original classification election did not take effect on the date of formation, the entity is generally locked into that classification for 60 months unless there has been a substantial ownership change. See Treas. Reg. §301.7701-3(c)(1)(iv) for details.
Revoking S Corporation Election
An entity that wishes to terminate its S corporation status effective January 1, 2026, must submit a written revocation statement to the IRS Service Center by March 16, 2026.
There is no standard IRS form for this revocation. The statement must include specific information required under IRS procedural guidance. If the IRS receives the revocation after March 16, 2026, it will not take effect until January 1, 2027, and the entity will be treated as a C corporation in the interim.
Relevant authority includes IRC §1362(d)(1)(C)(i) and IRM 3.13.2.23.15(1) (03-08-2023).
A Word of Caution
Most of these actions have significant implications for a taxpayer’s compliance profile and tax liability. Therefore, it’s crucial to undertake these actions only after a thoughtful, paid tax planning analysis. For those short on time, making prospective changes effective mid-year can offer a partial solution.
Entities should consult with tax professionals to navigate these complex decisions and ensure compliance with IRS regulations. Tax planning happens throughout the year, not just at tax time. A good tax advisor can save you valuable money and time, and help you avoid headaches and compliance issues.
