What the Form Is For
Form 1040 Schedule J allows eligible individuals with farming activities or fishing income to calculate their 2023 income tax using the income averaging method. This spreads part or all of their 2023 taxable income across three base years—2020, 2021, and 2022—rather than taxing the entire amount in one tax year.
The Internal Revenue Service offers this option because farming and fishing operations often experience unpredictable fluctuations in gross income, which can result in increased tax liability when one year's revenue is significantly higher than in other years. Income averaging helps reduce the impact of higher tax brackets in a single year and smooths out the long-term tax burden.
When You’d Use It (Including Late or Amended Filings)
You may use Schedule J if your farming or fishing trade business had unusually high income in 2023 compared to your earlier tax returns. You attach the form to your 2023 Form 1040 when filing your income tax return.
If you already filed and later determine that income averaging would lower your income tax, you can amend your return using Form 1040-X. If you do not have your 2020–2022 returns, you can request copies from the IRS using Form 4506 so your calculations match the agency’s records. Changes to any base years, whether corrected by you or the IRS, may require recalculating Schedule J.
Key Rules
- Qualifying business activities: You must have taxable income from a farming or fishing trade or business, which may include amounts reported on Schedule F, Schedule C, or Schedule E. It may also include amounts reported on portions of Schedule 1, Schedule D, or Form 4797 when the income is directly tied to your operation.
- Eligible individuals: You may use Schedule J even if you were not a farmer or fisher in all three base years, and your filing status does not need to be the same.
- Elected income limit: The elected farm income used for income averaging cannot exceed your total 2023 taxable income.
- Capital gains considerations: If elected farm income includes capital gains, you may need to reference the Schedule D instructions or prior-year information that originated from Form 8949.
- Loss and limitation rules: The Internal Revenue Code's net operating loss rules, passive activity limits, and at-risk rules must be applied before determining the amount of income to average.
- Nonqualifying items: Certain special calculations, such as those from Form 8814, Form 4952, Form 2555, or the Foreign Earned Income Tax Worksheet, do not affect Schedule J.
- Other taxes unaffected: Schedule J does not change self-employment tax or alternative minimum tax, which continues to follow the rules in Form 6251.
Step-by-Step (High Level)
- Identify 2023 taxable income: Start with taxable income on line 15 of Form 1040 and determine the amount derived from qualified farming activities or fishing income.
- Choose the portion for averaging: Decide how much of that business income should be used as elected farm income, understanding that using less may sometimes lower your tax more effectively.
- Calculate non-farm income tax: Compute the tax on your non-farm income using the 2023 tax tables or tax computation menu.
- Divide elected income: Split elected farm income into three equal parts and add one part to each of the three base years, then compute each year’s tax using that year’s tax rates found on the tax table.
- Combine and reduce: Add the recomputed taxes from all base years to the tax on your 2023 non-farm income, then subtract the original base-year taxes to determine your averaged amount.
- Confirm benefit: Compare the Schedule J result with your regular 2023 income tax and use Schedule J only if it reduces the amount owed.
Common Mistakes and How to Avoid Them
- Using incorrect base-year figures: Avoid errors by using precise taxable income from your prior tax returns, including any corrections made by the IRS or shown on amended filings.
- Including non-qualifying income: Prevent problems by excluding gains from land sales or other items not connected to qualified farming activities.
- Ignoring limitation rules: Stay accurate by applying net operating loss rules, passive activity limits, and at-risk requirements before deciding how much income can be averaged.
- Guessing prior-year amounts: Avoid mistakes by obtaining accurate figures through supporting documents or official copies and transcripts, rather than relying on estimates.
- Not verifying that averaging helps: Prevent unnecessary filing by comparing the Schedule J calculation with your standard 2023 tax, so you only attach the form if it lowers your income tax.
What Happens After You File
Once Schedule J is filed with your 2023 Form 1040, the IRS processes your income tax using the averaged calculation. Any refund or balance due follows the standard payment procedure. Schedule J applies only to one year, but your 2023 return may become part of the base amount for future Schedule J distributions if you use income averaging again.
Keep all documents that affect your taxable income for the base years used in Schedule J, because changes to earlier returns may require a recalculation. If prior-year information changes, you may need to file Form 1040-X to correct your Schedule J.
FAQs

Does Schedule J change the self-employment tax?
No, self-employment tax is calculated separately and is not affected by income averaging.
What if I do not have my earlier returns?
You can request them using Form 4506 to ensure your base-year figures are accurate.
Which forms report qualified income?
Income may appear on Schedule F, Schedule C, Schedule E, Schedule D, or Form 4797 when related to farming or fishing operations.
