IRS issues rules for Roth 401(k) catch-up requirement

On September 16, 2025, the IRS published final regulations relating to catch-up contributions to 401(k) and other elective contribution employer accounts. IR-2025-91. https://www.irs.gov/newsroom/treasury-irs-issue-final-regulations-on-new-roth-catch-up-rule-other-secure-2point0-act-provisions

The SECURE 2.0 Act of 2022 included some important changes for catch-up contributions to 401(k) accounts and other elective contribution employer accounts.

Effective for taxable years beginning after December 31, 2023, catch-up contributions by individuals who have $145,000 (subject to cost of living adjustments) or more of wages for the prior year could only be made to a Roth account, disallowing the exclusion from federal income taxes for that contribution.

In August, 2023, the IRS issued Notice 2023-62, which postponed the effective date for two years, until taxable years beginning after December 31, 2025.

The final regulations include the requirement that catch-up contributions for 401(k) plans must be designated as Roth contributions. Although the final regulations aren’t effective until taxable years beginning after December 31, 2026, the requirement in the tax law hasn’t been further postponed, so the requirement also applies for 2026.

Also note Roth contributions can’t be made unless the plan provides for them, so employees of companies whose plans don’t provide for Roth contributions can’t make catch-up contributions.

The catch-up contribution for employees who reach age 50 by the end of the tax year is generally limited to $7,500 for 2025, to be adjusted for inflation for future years. For taxable years beginning after 2024, plan participants who attain ages 60 through 63 have a higher catch-up contribution limit of 150% of the limit for other employees, or $11,250 for 2025, to be adjusted for inflation in future years.

The final regulations also include rules for other retirement plans, such as SIMPLE plans.

Employers and their plan administrators should meet with their tax advisors and legal counsel about updating their retirement plans for the new final regulations.

Do you qualify for the new federal tips deduction?

The IRS has issued proposed regulations for what tips qualify for the new federal tips deduction. (IR-2025-92, Prop. Reg. 110032-25, published September 22, 2025. https://www.federalregister.gov/documents/2025/09/22/2025-18278/occupations-that-customarily-and-regularly-received-tips-definition-of-qualified-tips

The deduction is up to $25,000 of qualifying tips received by an individual or a married couple. It’s not an itemized deduction. The social security number of the individual or individuals claiming the deduction must be reported on the income tax return. Married persons must file a joint return to claim the deduction.

The deduction for qualified tips phases out by $100 for each $1,000 over $150,000 of modified adjusted gross income ($300,000 for joint returns.)

The deduction applies for 2025 through 2028.

The deduction applies for employees who receive Form W-2, independent contractors receiving Forms 1099-K or 1099-NEC, and certain business owners.

Qualifying tips must be voluntary and determined by the payor. For example, an automatic tip specified by a restaurant without expressly providing an option to disregard or modify the amount doesn’t qualify for the deduction. Any tip paid in excess of the automatic amount qualifies for the deduction. (Some restaurants might have to segregate accounting for tips that qualify and those that don’t.) When a customer must choose from a list of tip percentages that doesn’t include “no tip”, that tip doesn’t qualify for the deduction.

The proposed regulations include a list of occupations that might qualify for the deduction.

One of the listed occupations is “digital content creator”, so a person who produces a video podcast might qualify to claim the tips deduction.

The services may not be performed in a “specified service trade or business”, as defined for the Qualified Business Income Deduction at Internal Revenue Code Section 199A(d)(2). For a self-employed person, the “specified service trade or business test” is determined based on that person’s occupation. For an employee, the “specified service trade or business test” is determined based on the business of the employer.

For example, a self-employed comedian who receives tips for performing doesn’t qualify for the tips deduction, despite being on the list of qualifying occupations, because “performing arts” is a specified service trade or business.

A pianist who receives tips as an employee of a hotel when playing in the hotel lobby does qualify for the tips deduction, because a hotel isn’t a specified service trade or business.

The IRS has issued a draft Form 1-A for claiming the tips deduction. https://www.irs.gov/pub/irs-dft/f1040s1a–dft.pdf

Remember, the income tax laws of many states, such as California’s, haven’t conformed to this new tax law.

There are many deductions with different phaseouts under the One Big Beautiful Bill Act as well as other limitations under the Internal Revenue Code. I suggest that tax planning computations be made by a tax consultant who is familiar with the new rules using tax planning software that has been updated for recent tax law changes.

Research expensing and 2024 income tax returns

Technology companies have finally achieved tax relief for domestic research and experimentation (R & E) expenses. Certain “small businesses” can elect to currently deduct them on their extended or superseding 2024 income tax returns and amending or filing an administrative adjustment request for their 2022 – 2023 return.

In order to achieve budget goals, the Tax Cuts and Jobs Act of 2017 included a provision requiring that research and experimental expenses incurred after December 31, 2021 be capitalized and amortized over a 60-month period. The plan was for the amortization requirement to be repealed before it became effective. From that time, technology companies have been lobbying Congress to restore the election to currently expense R & E expenses.

Finally, the expense election was restored for domestic R & E expenses by Section 70302 of the One Big, Beautiful Bill Act of 2025 (OBBBA), effective for tax years beginning after December 31, 2024. https://www.congress.gov/bill/119th-congress/house-bill/1

Most corporations may elect to deduct the unamortized balance of domestic R & E expenses that were previously capitalized for 2022 through 2024 over a one- or two-year period, starting for 2025. (OBBBA Section 70302(f)(2).)

Alternatively, certain small businesses that have average gross receipts of $31,000,000 or less for a taxable year beginning in 2025 may elect to amend their tax returns for 2022 – 2024 and currently deduct amounts that were previously capitalized and amortized. The election must be made by Monday, July 6, 2026. (Note the due date for filing an amended return supersedes that date. For example, a corporation that timely filed its 2022 income tax return, with no extension filed, on April 15, 2023 may not file an amended income tax return after April 15, 2026.) (OBBBA Section 70302(f)(1), Revenue Procedure 2025-28, Sections 3.02(1) and 3.03(3).) (Instead of filing amended income tax returns, partnerships file administrative adjustment requests (AARs).)

According to OBBBA Section 70302(f)(1)(A), the small business expense election should be made on an amended income tax return or an AAR. Many corporations still haven’t filed their 2024 income tax returns, with an extended due date of October 15, 2025. The American Institute of Certified Public Accountants and technology companies asked the IRS to allow them to make the election for 2024 on an originally-filed income tax return.

On August 28, 2025, the IRS issued Revenue Procedure 2025-28. https://www.irs.gov/pub/irs-drop/rp-25-28.pdf According to the Revenue Procedure, certain small business taxpayers may make the election to currently deduct R & E expenses on an originally-filed income tax return. (Rev. Proc. 2025-28, Section 3.03.) In addition, the IRS said that a six-month automatic extension of time to file is granted to any business that didn’t previously request one, and a business that previously filed a 2024 income tax return without electing to currently deduct R & E expenses may make the election by timely filing a superseding income tax return that includes the election. (Rev. Proc. 2025-28, Section 8.)

A business that deducts domestic R & E expenses on an original federal income tax return and complies with the requirements of Rev. Proc. 2025-28, Section 3.03 for all other applicable tax years will be deemed to have made a current-expense election. (Rev. Proc. 2025-28, Section 3.03(4).)

Instead of filing a change of accounting Form 3115, the taxpayer should attach a statement to the income tax return with similar information specified in the Revenue Procedure. (Rev. Proc. 2025-28, Sections 3.03(2) and 3.04.)

Taxpayers should consider the cost of preparing amended income tax returns and AARs, and that the IRS takes about a year to process them, when making the decision whether take to amended return/AAR route, including deducting the expenses currently on the 2024 income tax return, or simply deducting unamortized domestic R & E expenses on their 2025, or 2025 and 2026, income tax returns.

I highly recommend consulting with a qualified tax return preparer when implementing this change.
