Farmers and fishermen get a choice that most self-employed workers do not: skip the quarterly estimated tax payments for 2026 and settle everything at filing time. The IRS explains the rule in its 2026 Form 1040-ES. A filer who sends the 2026 Form 1040 or 1040-SR by Monday, March 1, 2027, and pays the total tax due does not need to make 2026 estimated payments to avoid a penalty.
There are two ways to meet the rule, and the filer picks one. Pay the whole estimated tax by Friday, January 15, 2027, in a single payment, or file the return by March 1, 2027, and pay what is owed with it. The test for who counts is about income, not a job title, so a farmer or fisherman has to know where the money came from in 2025 and 2026 before choosing.

Who counts as a farmer or fisherman for this rule?
The form sets an income test. At least two-thirds of gross income for 2025 or 2026 must come from farming or fishing. When that is true, the 90% test used for other filers changes to 66 2/3%, according to the IRS instructions. The form does not separately define the words farmer or fisherman, so the income figure is the measure.
The test looks at either year. A producer whose 2025 income was mostly from the farm or the boat can qualify even if a bad 2026 season shifted the mix, and the reverse holds too.
Why would a filer choose January 15 over March 1?
Paying everything by January 15, 2027, closes out the year’s estimated tax in one payment and leaves the filing date open. The filer can pay a good-faith estimate in January and file the return on the ordinary schedule. The cost is that the whole payment has to be sized before the year’s books are final.
Filing by March 1 reverses the order. Books and receipts come first, the return second, and the payment goes with the return. The IRS says that under this option, 2026 estimated tax payments are not required to avoid a penalty.
How does this compare with the rule for everyone else?
Most filers who pay estimated tax face four installments, and the last one falls on January 15, 2027. The IRS gives them a narrower exception: no January payment if the return is filed by February 1, 2027, with the entire balance paid. The farm and fishing rule is wider, because it excuses all of the year’s payments and allows an extra month.
The general rule still frames the whole question. In most cases, the form says, estimated tax is required when a person expects to owe at least $1,000 in tax for 2026 after withholding and refundable credits. Farmers and fishermen who expect to owe less than that have no estimated payment to worry about.
What does a mistake cost?
The IRS says the penalty for underpaying “is imposed on each underpayment for the number of days it remains unpaid.” Meeting the March 1 option requires both halves: the return filed and the total tax paid. A return filed on time with a balance left over does not fit the description the form gives.
The form lists several ways to send money, including an online account at IRS.gov/Account, IRS Direct Pay from a bank account, a debit or credit card, a digital wallet with a provider fee, and a check or money order mailed with the payment voucher. The agency’s main site, IRS.gov, carries each option.
The IRS sets two dates and a single income test, leaving the choice between them to each filer. The open question for a farm or fishing household is which date its books can actually support.
Pay by January 15 or file by March 1 on farm or fishing income?
Whichever date a farm or fishing household picks, the choice sets up the letters that follow. A return filed in late winter with a balance or a refund brings IRS notices and status checks that are easy to misread.
The IRS Refund Recovery Kit includes a notice decoder (Part 4, “Why It Stalled: The Notice Decoder”) and a refund status tracker spreadsheet, so each date, amount and letter from the 2026 return sits in one place.
