Rev Proc 2003-43: A Plain-English Guide

The procedure governed late subchapter S elections for a full decade. Thousands of rulings, articles, and engagement memos were written against it.

Those documents did not disappear when the rule changed. Practitioners still open files that reference it as though it applied.

Reading it correctly means knowing what it said and when it stopped mattering. Both halves are necessary.

The procedure stated a narrow purpose. It supplied a simplified method to request relief for four late elections. Those were the S corporation election, two trust elections, and the subsidiary election. Relief was available within twenty four months of the election's due date.

Congress had authorized this kind of forgiveness in 1996. Before the procedure, most taxpayers needed a private letter ruling. That meant a user fee and a wait measured in months. The simplified route removed both barriers.

Relief required the entity to fail solely because of the untimely filing. The taxpayer wrote a notation at the top of the election form. It also attached a statement explaining the failure. The original text is archived there on the agency's site.

The required standard differed by election type, which surprises people. S corporation and subsidiary elections required reasonable cause. Trust elections required only that the failure was inadvertent. That distinction carried real weight in borderline cases.

The procedure sorted filers by whether a return had been filed. That sorting determined the actual deadline. It is the feature most people misremember.

If no return had been filed for the first intended year, one track applied. The request was due at the earlier of two dates. Eighteen months from the election's due date was one. Six months after the first return's due date was the other.

If a return had been filed, a different track applied. That track required the return to have been filed within six months of its due date, excluding extensions. Meeting that condition allowed the full twenty four month window. Missing it pushed the taxpayer toward a ruling request.

The current procedure took effect in September 2013. It modified and superseded this one along with several others. It also applied to requests already pending at that time. The consolidation was noted then as a long overdue simplification.

Two rows do most of the practical work. The clock now runs from the date you wanted rather than the date the form was due. And the two track structure vanished, replaced by a single window plus a consistency requirement.

The window itself expanded considerably. Twenty four months became three years and seventy five days. For a calendar year filer, that is roughly a fifteen month extension. Many requests that would have failed under the old rule now succeed.

You will encounter this procedure in inherited files and older research. Handling it correctly takes a short checklist. Work through it before relying on anything you find. Recent rulings applying these procedures were surveyed recently in professional commentary.

• Treat any reference to the 2003 procedure as historical rather than operative
• Check the document's date, since anything before September 2013 predates the change
• Recompute the deadline from the intended effective date, not the election due date
• Confirm which of the current five categories your election falls into
• Write the current procedure reference on the form, never the superseded one
• Read older rulings for their reasoning rather than for their deadlines
• Verify whether later guidance has since amplified the current rule

The notation point causes real rejections. A form filed today citing the 2003 procedure routes incorrectly. The processing clerk is matching text against current guidance. Use the current reference even if your research materials say otherwise.

Private letter rulings issued between 2003 and 2013 applied this procedure. Their reasoning on intent, reasonable cause, and consistency remains instructive. The conditions carried forward substantially into the current rule. Only the deadlines and the track structure changed.

That continuity makes older rulings genuinely useful. A ruling analyzing whether an owner's belief was reasonable still illuminates the standard. A ruling computing a twenty four month deadline does not. Separate the analysis from the arithmetic.

Inherited engagement files pose the same problem. A memo written in 2010 may correctly describe the conditions and wrongly state the window. Update the deadline and keep the analysis. Rewriting from scratch is usually unnecessary.

Rev Proc 2003-43 supplied the simplified late election route from 2003 through 2013. It allowed twenty four months from the election's due date and split filers into two tracks. It covered four elections and applied different standards to corporate and trust elections. It has been modified and superseded.

Use it as history rather than authority. The current procedure runs three years and seventy five days from your intended effective date. It covers five categories and drops the two track structure entirely. When an old citation appears in a file, keep the reasoning and replace the deadline.
