Alabama

Paper returns with 2D barcodes are not considered electronically filed.

An “opt out” election form (Form EOO) must be attached to any paper return submitted by a preparer subject to the electronic filing requirements of Rule 810-27-.09. A 2D barcode is still required on any such paper return.

If an income tax return preparer prepares 11 or more acceptable, original individual income tax returns using tax preparation software in a calendar year, then for that calendar year and for each subsequent calendar year thereafter, all acceptable individual income tax returns prepared by that income tax preparer must be filed using electronic technology, as defined in the “Electronic Tax Return Filing Act,” and as codified in Chapter 30 of Title 40, Code of Alabama 1975.

For 1120, 1120-S, and 1065 returns, if an income tax return preparer prepares 25 or more acceptable, original corporation and partnership income tax returns using tax preparation software in a calendar year, then for that calendar year and for each subsequent calendar year thereafter, all acceptable corporation and partnership income tax returns prepared by that income tax preparer must be filed using electronic technology, as defined in the “Electronic Tax Return Filing Act,” and as codified in Chapter 30 of Title 40, Code of Alabama 1975. This shall cease to apply to an income tax preparer if, during that calendar year and all subsequent years, the income tax preparer prepared no more than 15 original corporation and partnership income tax returns.

Arkansas

A tax practitioner who files a taxpayer’s federal income tax return electronically shall also file the taxpayer’s Arkansas income tax return electronically. The secretary may waive the electronic filing requirement if the secretary determines that filing a taxpayer’s Arkansas income tax return electronically would cause an undue hardship on the tax practitioner. This is for tax years beginning on or after January 1, 2021. This mandate applies to the following income tax returns: Individual Income Tax, Corporation Income Tax, S Corporation Income Tax, Partnership Tax, Fiduciary Income Tax, Pass Through Entity Tax, and Composite Income Tax.

Tax practitioners may request a waiver for the electronic filing requirement by submitting the Arkansas Preparer e-File Hardship Waiver Request (AR8944) to the following:

• Email: arefile@dfa.arkansas.gov

• Mailing Address:

Arkansas e-File Section

California

Business returns prepared using a tax preparation program must be electronically filed. This includes original and amended corporation, S corporation, partnership, and Limited Liability Company returns. Business entities may annually request a waiver from this mandate and the Franchise Tax Board may grant a waiver for the following reasons:

• Technology constraints – The tax preparation program is unable to e-file the return due to the complex nature of the return or inadequacy of the program.

• Compliance would result in undue financial burden.

• There are other circumstances that constitute reasonable cause and not willful neglect.

For taxable years beginning on or after January 1, 2017, business returns that do not comply with the mandate (not including businesses that receive a waiver from the Franchise Tax Board) will be subject to a first time penalty of $100 and subsequent penalties of $500. Group returns will be subject to the penalty at the combined reporting group level and not at the member level.

Connecticut

Connecticut agency regulations Section 12-690-1 require tax return preparers who prepared 50 or more CT income tax returns during any calendar year to e-file all CT income tax returns. Preparers may obtain a one-year waiver from the e-file requirement by establishing that they cannot e-file a return without experiencing an “undue hardship” (Regs. Section 12-690-1). This waiver (CT Form DRS-EWVR) can be completed using CT screen EWVR.

The following returns, and their associated payments, must be transmitted electronically for tax years on and after 2015:

Illinois

A tax return preparer must e-file Illinois individual income tax returns if both of the following are true:

• The preparer files more than 10 Illinois individual income tax returns in a calendar year.

• The preparer is required to e-file federal individual income tax returns.

EXCEPTION: A tax return preparer is not required to e-file a return if the taxpayer directs them not to do so. To document this choice, the taxpayer must complete and sign Form IL-8948, and the tax return preparer must keep it on file for three years. Do not mail Form IL-8948 to the Illinois Department of Revenue unless requested.

Indiana

• If a professional preparer files more than 10 individual income tax returns in a calendar year, for the subsequent year the professional preparer must file returns for individuals in an electronic format, as specified by the IN Department of Revenue. A penalty of $50 may be imposed on the professional preparer for each return that is not e-filed. (See exception below.) The maximum penalty is $25,000 per preparer per calendar year.

EXCEPTION: An individual taxpayer may elect to opt-out of having their return e-filed. Form IN-OPT must be completed, signed, and retained on file by the paid preparer. A return filed under these circumstances will not be subject to a penalty for not being e-filed.

• Pass-through entity returns (S corporations, partnerships, and fiduciaries) with more than 24 Indiana Schedules K-1 must be filed electronically.

• The State of Indiana does not allow returns containing the following forms to be e-filed:

Kansas

Preparers who file 50 or more returns per year are required to file at least 90% of their returns electronically. The requirement applies to any paid preparer who prepares 50 or more individual income tax returns during any calendar year. The combined total of the returns prepared by all employees at all of the tax preparer’s locations will be used to determine whether or not the tax preparer is subject to the e-filing mandate. Once a tax preparer meets the 50 or more individual income tax return threshold for any calendar year, the e-file requirement also applies to all future years in which the preparer prepares KS individual income tax returns.

The Kansas DOR Secretary may waive the e-file requirement if it is determined that complying with the requirement would cause undue hardship.

Kentucky

Tax return preparers who file 10 or more individual income tax returns are required to e-file their clients' returns. A paid preparer who fails or refuses to comply with the mandate must pay a $10 return processing fee for each return not filed as required, unless the failure is due to reasonable cause.

KY Form 8948-K, Preparer Explanation For Not Filing Electronically, is used to explain why a particular return is being filed by paper. The form should be attached to and mailed with the paper return with an explanation of the exception to the mandate. The lack of compatible computer hardware, internet access, or other technological capabilities determined relevant by the department are a few examples of a reasonable cause to not e-file their client's returns.

The ERO must retain Form 8879-K. (Form 8879-K is not required for federal or state e-filed returns with federal PIN.) Acceptance into the Kentucky e-file program is automatic with acceptance into the federal e-file program.

Louisiana

Any tax return preparer who prepares more than 100 LA individual income tax returns during any calendar year must file them electronically.

Every fiduciary that files a LA fiduciary income tax return must e-file the return with the DOR using the format prescribed by the department as follows:

• When for the previous calendar year, the tax return preparer prepared 10 or fewer original Maine tax returns for individual income tax that are eligible for e-file

• When the taxpayer refuses to allow the return to be e-filed and the tax return preparer notes the refusal in the taxpayer’s records

• When the taxpayer has been granted a waiver from mandatory participation under section .08 of Rule 104.

Maryland

A preparer who has prepared more than 100 qualified returns in the prior taxable year is required to file the returns electronically. Maryland House Bill 810 authorizes the Comptroller to impose on a preparer a $50 penalty for each return that is not filed electronically in compliance with this act, unless the preparer is able to show that the failure to comply is due to reasonable cause and not due to willful neglect. The total penalties assessed may not exceed $500 for all returns filed by the preparer in a taxable year. Waivers are available (Tax-General Article §10-824).

Michigan

To optimize operational efficiency and improve customer service, the Michigan Department of Treasury has mandated e-file of individual income tax returns.

The IRS mandates preparers filing 11 or more income tax returns to e-file those returns, with minor exceptions. Michigan would expect any preparer e-filing federal returns to also e-file Michigan returns. This mandate also applies to City of Detroit returns.

The MI Department of Treasury will be enforcing the e-file mandate for CIT. The enforcement includes not processing computer-generated paper returns that are eligible to be e-filed. A notice will be mailed to the taxpayer, indicating that the taxpayer’s return was not filed in the proper form, and content, and must be e-filed. Payment received with a paper return will be processed and credited to the taxpayer’s account even when the return is not processed.

Mississippi

Minnesota

Preparers who filed more than 10 MN returns last year are required to e-file all MN returns, unless the taxpayer indicates otherwise. This requirement also applies to preparers in other states. The requirement does not include returns prepared for Homestead Credit refunds, renter’s property tax refunds, amended income tax returns, or returns filed with other states. If the taxpayer does not want the preparer to e-file the return, mark the appropriate E-file Opt Out option on MN screen M1.

The state imposes a $5 per tax return penalty on the tax return preparer (who falls under the mandate) for any return not e-filed. This is true even if the taxpayer indicates they do not want the return e-filed.

For more information, see the MN Department of Revenue website.

New York

Tax return preparers and their firms must e-file all authorized tax documents if they both prepared at least one authorized tax document for more than 10 different taxpayers during calendar year 2023 and either:

• Will use tax preparation software to prepare one or more tax documents in 2024 (If the document cannot be e-filed, the preparer does not have to count it to determine if they meet the “more than 10 different taxpayers” threshold.)

• Were previously mandated to e-file returns (Once the preparer is subject to the mandate, they must e-file returns for all subsequent years, even if they no longer meet the requirements.)

New York State accepts e-filed returns for tax years 2022, 2023, and 2024. Tax year 2022 returns fall under the mandate processing year in 2025. The mandate applies to tax return preparers and their firms located within and outside New York State. Clients of tax return preparers cannot opt out of e-file. Tax return preparers who do not comply with the e-file mandate may be subject to a $50 per document penalty. Once a tax return preparer or their firm is subject to the mandate, the mandate continues to apply to them in all following years, even if that tax return preparer or the firm no longer meets the threshold. A tax return preparer may have been initially subject to the e-file mandate because they prepared more than five New York State tax documents in 2021. Tax return preparers and their firms cannot charge a separate fee to e-file client's tax returns. Tax return preparers who do not comply may be subject to a $500 penalty for the first-time charge, and a $1,000 penalty per subsequent charge.

Ohio

Preparers who file more than 11 original tax returns during any calendar year must use electronic technology to file their clients’ OH personal income tax returns.

Oregon

Individual Returns

Paid preparers who meet the requirements of the federal e-file mandate—who anticipate preparing 11 or more federal individual or trust tax returns during the year—must e-file Oregon personal income tax returns. Form 8948, Preparer Explanation for Not Filing Electronically, is used to explain why a particular return is being paper filed.

Business Returns

If a corporation is required to e-file its federal return, then the corporation is also required to e-file the Oregon return.

Rhode Island

Any paid preparer who filed more than 100 RI tax returns during the previous calendar year must e-file all eligible tax returns. A person employed by a paid preparer with multiple offices is required to e-file if the total of all tax returns filed from all offices is more than 100, regardless of whether a single office of the same preparer files fewer than 100 returns. If a paid preparer fails to abide by the e-file mandate, or otherwise causes clients’ RI tax returns to be filed falsely or improperly, the Tax Administrator may, after a hearing to show cause, preclude such preparer from preparing and filing RI tax returns with the Tax Division (Regulation ELF 09-01).

South Carolina

Any preparer who prepares 100 or more returns for a tax period for the same year is required to submit those returns electronically where electronic means are available. Where electronic means are not available to file the return, but 2D barcode is available, the preparer must use 2D barcode. This number includes any SC tax return that is prepared, regardless of tax type. If compliance with this section is a substantial financial hardship, a tax return preparer may apply in writing to the department to be exempted from these requirements. The address is:

Electronic Filing Mandate Exemption Application

PO Box 125

Columbia, SC 29214

The department may grant an exemption for no more than one year at a time. A person who fails to comply with the provisions of this section may be penalized in an amount to be assessed by the department equal to $50 for each return.

Utah

Tax preparers that file more than 101 income tax returns in a calendar year are required to file all such returns using scan technology or by electronic means. All sales tax returns, schedules, and related filings, including monthly and quarterly/annual returns, must be electronically. The filing requirement will not apply if:

• A schedule must be attached to the return that cannot be filed using scan technology or electronic means.

• The taxpayer requests in writing that the income tax preparer not file the return using scan technology or electronic means.

• The Utah Tax Commission waives the requirement that a return be filed by scan technology or electronic means. A tax preparer may obtain such a waiver from the commission by demonstrating that the use of scan technology or electronic means would result in an undue hardship.

The filing requirement does not apply to amended returns or returns for any taxable year that begins before the first day of the current taxable year. If a preparer or multiple preparers affiliated with the same establishment prepared 101 or more returns in the prior calendar year, they must submit all UT individual tax returns electronically.​

In the absence of an approved hardship waiver, a tax return preparer required to e-file is liable for a penalty of $25 for each return not filed electronically; however, if a taxpayer receiving services from a tax return preparer who is required to file all WV income tax returns electronically elects (opts out) of having their return electronically filed, they must complete and sign Form OPT-1. The penalty of $25 still applies.
