Tax penalty relief planning under IRS Notice 2026-3

Estimated tax penalties remain one of the most common and frustrating issues for taxpayers with fluctuating income. These penalties often arise not from noncompliance but from timing mismatches between income recognition and payment requirements. IRS Notice 2026-3 provides important clarification for a specific situation by explaining how taxpayers who make a valid election under §1062(a) may qualify for relief from estimated tax penalties under §§6654 and 6655.

What the §1062(a) election allows

Under §1062(a), taxpayers who recognize a gain from the sale of qualified farmland property to a qualified farmer may elect to pay the tax liability attributable to that sale in four equal installments rather than in full by the original due date of the return. This provision is designed to address cash flow challenges that can arise when a large gain is realized from a qualifying farmland sale.

Before the notice, the interaction between this election and estimated tax rules was unclear. Even when taxpayers properly elected to spread their tax payments over installments, they could still face estimated tax penalties because the deferred tax remained part of the penalty calculation. The new guidance resolves that inconsistency.

Estimated tax rules

• Individuals §6654: Generally, must pay estimated tax in four installments, each 25% of the required annual payment, which is the lesser of 90% of current year tax or 100% (110% for high-income taxpayers) of prior year tax.
• Corporations §6655: Also pay estimated tax in four installments, each 25% of the required annual payment, which is the lesser of 100% of current year tax or 100% of prior year tax (with limitations for large corporations). 

How Notice 2026-3 affects estimated tax penalties

When a taxpayer makes a valid §1062(a) election, the portion of tax deferred under the installment election may be excluded when calculating required estimated tax payments. This means the deferred tax is not considered in determining additions to tax under §6654 for individuals or §6655 for corporations.

For tax professionals, this clarification is significant. It aligns estimated tax requirements with the statutory installment framework and provides penalty relief when taxpayers properly elect to spread tax payments related to a qualified farmland sale.

Without relief, taxpayers making a §1062(a) election would be required to include the entire gain in their estimated tax calculations for the year of sale, potentially negating the benefit of the installment payment option by triggering estimated tax penalties if they do not prepay the full tax.

Requirements for relief

Valid §1062 Election: The taxpayer must properly make a §1062 election, including attaching a copy of the required covenant or restriction to the return for the year of sale.

Proper Calculation: The taxpayer must calculate estimated tax installments for the year of sale by including only the portion of the gain required to be paid with the first installment (25% of the applicable net tax liability).

No Acceleration Impact: If the due dates for installments are accelerated (e.g., due to nonpayment or other events), this does not affect the penalty relief for the year of sale.

Compliance requirements remain critical

The penalty relief applies only when eligible taxpayers properly make the election on a timely filed return and comply with all installment payment deadlines. 

Accurate reporting and documentation are essential. The election and related calculations should be clearly reflected on the return. The election must also be supported by records showing the qualifying sale and installment amounts.

Bottom line

IRS Notice 2026-3 provides welcome clarity and targeted penalty relief for taxpayers who elect to spread tax payments from a qualified farmland sale under §1062(a). For tax professionals, this guidance offers an opportunity to add value through informed planning and proactive client communication.
