IRS Schedule J – Income Averaging

Schedule J (Form 1040), Income Averaging for Individuals With Income From Farming or Fishing, lets an eligible individual elect to calculate 2025 income tax by spreading elected farm income across the three preceding base years for rate-computation purposes. The 2025 title changed from the older “Farmers and Fishermen” wording.

The election can help when 2025 farming or fishing income is high and taxable income in one or more of 2022, 2023, and 2024 was lower. It does not move income into those years or amend the base-year returns.

How the IRS classifies and files this form

Document type: income-tax averaging election attached to an individual return.

Schedule J is attached to Form 1040, 1040-SR, or 1040-NR only when the taxpayer elects to use its computed tax. The tax from line 23 is included on the return’s tax line.

What income can be elected

Elected farm income is taxable income attributable to a farming or fishing business, including qualifying gains and losses from property regularly used in that business. It does not include land, development rights, grazing rights, or similar rights described as excluded by the instructions. The taxpayer may elect less than the full eligible amount when that produces a better result.

The three base years

The schedule uses taxable income and tax information from 2022, 2023, and 2024, adjusted when prior Schedule J elections or amended returns affect the entries. A taxpayer did not have to conduct a farming or fishing business during the base years, and filing status may differ between years.

What income averaging does not change

Schedule J computes current-year regular income tax. It does not reallocate income legally to prior years, reopen those years, change prior AGI, or generally change self-employment tax. The election also does not apply to the alternative minimum tax calculation.

Comparing the tax result

The completed Schedule J result should be compared with the tax produced by the 2025 Tax Table, Tax Computation Worksheet, Qualified Dividends and Capital Gain Tax Worksheet, or Schedule D Tax Worksheet as applicable. The form itself warns taxpayers to attach Schedule J only if they use it to figure tax.

Records and related schedules

Keep copies of the three base-year returns and any prior Schedules J. Current farming or fishing income can originate on Schedule F, Schedule C, Schedule E, Schedule D, Form 4797, Form 4835, Form 8949, and other sources identified by the instructions.

Income-averaging errors

• Using gross farm receipts instead of taxable income attributable to the business.
• Averaging all taxable income rather than an elected eligible amount.
• Changing prior-year returns to reflect the election.
• Ignoring a prior Schedule J when entering a base year.
• Attaching Schedule J when the regular tax computation is lower.

Farming and fishing definitions

The instructions define farming to include cultivating land, raising or harvesting agricultural or horticultural commodities, qualifying nurseries, and raising or managing animals. Certain share-based leases can qualify, while fixed-rent leasing, contract harvesting for someone else, or merely reselling plants or animals may not.

Fishing includes catching or harvesting fish for commerce and specified supporting operations, share-based vessel leasing, and qualifying crew compensation. Scientific research and activities outside the definition do not become eligible simply because they occur on water.

Capital gains within elected farm income

Qualifying gain from property regularly used in the farming or fishing business may enter elected farm income, including some property sold within a reasonable time after the business ends. Land and specified rights are excluded. When elected farm income contains net capital gain or unrecaptured section 1250 gain, lines 2b and 2c preserve the proper rate computation.

This interaction is why Schedule D and Form 4797 records may be needed even when the taxpayer’s main operating result comes from Schedule F.

Information used in the averaging calculation

This cross-check identifies the records and calculations that should agree before Schedule J is filed. It is especially useful when several statements or supporting forms feed one line.

Resolve any Schedule J difference at the source rather than forcing it into the final total. Retain this reconciliation and the documents behind it with the tax records even when the worksheet itself is not submitted to the IRS.

Questions taxpayers commonly ask

Must I have farmed in all three base years?

No. The 2025 instructions say the taxpayer is not required to have been in farming or fishing during any base year.

Does Schedule J reduce self-employment tax?

The election concerns the regular income-tax calculation; it does not generally recalculate self-employment tax.

Can I average only part of eligible farm income?

Yes. The instructions permit electing less than the entire eligible amount, subject to the form’s limits.
