RTE/2023-8 July 2023 Filing Dates and Estimated Tax Payments ∗ Carol Bishop, Extension Educator University of Nevada Reno Introduction The information presented here is intended for sole proprietors. Entities will have differing requirements. Knowing the deadline to file your federal income tax return is important, as late filing can generate penalties. In addition, taxpayers should know when tax payments are due because payments can be a major expense to consider in cash flow planning. When managing the cash flow of the farm or ranch, it is important to preserve cash as long as possible. With this in mind, you must be familiar with three areas: 1. Filing deadlines, 2. Estimated tax filing requirements, and 3. Potential underpayment of estimated tax penalties Individual Income Tax Return A producer filing a Form 1040, Individual Tax Form, with a Schedule F, Profit or Loss From Farming, or Form 4835, Farm Rental Income and Expenses, has the same filing deadline as every other taxpayer. For a calendar year1 filer, the deadline is generally April 15, unless that date falls on ∗ This material is based upon work supported by the U.S. Department of Agriculture, under agreement number FSA21CPT0012032.

For the fiscal year2 filer, the deadline is the fifteenth day of the fourth month following the close of the year. The weekend/holiday rule also applies to fiscal-year filers. Individual taxpayers are also entitled to extend the deadline by six months by filing Form 4868, Application for Automatic Extension of Time to File U.S. Individual Income Tax Return. Note that Form 4868 allows an extension of time to file the return, and does not extend the deadline to pay income tax owed on the return. Underpayment of Estimated Tax Penalty A taxpayer who files their income tax return and has a balance due of $1,000 or more may be assessed a penalty for underpayment of estimated tax. The penalty is computed by multiplying the current interest rate for underpayments by the amount of underpaid tax. Form 2210, Underpayment of Estimated Tax by Individuals, Estates and Trusts or Form 2210-F, Underpayment of Estimated Tax by Farmers and Fishermen is used to calculate the underpayment penalty. The interest rate can fluctuate quarterly but at the time of writing was at 4% . If the taxpayer is a resident of the United States for the entire preceding year and did not have any tax liability, they are exempt from the underpayment of estimated tax penalty. The taxpayer is also exempt if during the year or preceding year the taxpayer was age 62 or greater and retired, or became disabled during the year. However, the underpayment must be due to reasonable cause and not willful neglect. Avoiding Penalties The penalty for underpayment of estimated tax can be avoided by paying income tax ahead. This can be accomplished through income tax withholding from non-farm income, such as W-2 wages, or by making estimated tax payments. To avoid this penalty, a taxpayer must pay ahead, through withholding or estimated tax payments an amount equal to the smaller of: • 90% of the tax on the current year return, or • 100% of the tax owed the prior year (110% if you are not a farmer, your prior year adjusted gross income was more than $150,000, and you filed a joint return) . A taxpayer can also avoid a penalty for underp

FAQs

What are the main federal income tax filing deadlines for individual returns?

For calendar-year filers, the deadline is generally April 15, moving to the next business day if it falls on a weekend or holiday. For fiscal-year filers, it is the fifteenth day of the fourth month following the close of the year, with the same weekend/holiday rule.

How can taxpayers extend the deadline to file their individual income tax return?

Taxpayers can extend the filing deadline by six months by filing Form 4868. The extension applies to time to file, not to the deadline to pay income tax owed.

When might an underpayment of estimated tax penalty apply, and how is it calculated?

A penalty may be assessed when the return is filed with a balance due of $1,000 or more. It is computed by multiplying the current interest rate for underpayments by the amount of underpaid tax, using Form 2210 or Form 2210-F.
