Under OB3, eligible workers can deduct qualified tips and overtime for 2025-2028. Great news for service and shift workers. Recent guidance breaks it down for both individuals and businesses, making it easier to navigate. Qualified tips are voluntary payments in occupations where tipping was customary as of Dec. 31, 2024, with a max deduction of $25,000 (phasing out over $150,000 MAGI for singles, $300,000 joint).
On the overtime side, this is an above-the-line deduction for FLSA-required premium pay, max $12,500 ($25,000 joint, phasing out similarly). Taxpayers must include SSN and file jointly if married.
For workers: IR-2025-114 and Notice 2025-69 walk through calculations using W-2s, 1099s, and Form 4137, with handy examples.

Speaking of relief, the IRS is cutting employers some slack on the new tip and overtime reporting under OB3 for 2025. Forms stay the same this year, with changes coming in 2026. This transition help is a lifesaver for payroll teams. This applies to cash tips and qualified overtime, aiming to ease the shift while systems update.
Details in the notice aim to smooth things out as systems get updated.
Key takeaways from Notice 2025-62:

• Provides relief from penalties for failure to file correct information returns or furnish correct payee statements for qualified tips and overtime in 2025.
• Applies to Forms W-2 and 1099 series, helping employers and payors during the transition.
• Relief is available if reasonable cause is shown and systems are being updated in good faith.
• Employers must make a good faith effort to comply with the new reporting requirements.
• Effective for returns and statements due in 2026 related to 2025 payments.

Digital assets are getting more scrutiny with final regs on broker reporting. Starting with 2025 deals, covered brokers must use the new Form 1099-DA for sales and exchanges, focusing on gross proceeds first, with basis later. This is part of broader efforts to ensure compliance in crypto and digital spaces.
Advise clients to track wallet activity, acquisition dates, and basis meticulously.
Even without a 1099-DA, income must be reported. Add crypto questions to your organizers.

Thanks to OB3, the 1099-K threshold is back to the old standard: over $20,000 and 200+ transactions. This overrides prior phased-ins, per Fact Sheet 2025-08 and IR-2025-107, applying to third-party settlement organizations like payment apps and online marketplaces.
Taxable income from apps/platforms still needs reporting, form or no form.

As 2025 winds down, a withholding review can prevent surprises come filing time. IR-2025-52 is a good nudge. Tie this into OB3 perks like higher standard deductions, senior breaks ($6,000/$12,000 for 65+, phasing out at $75k/$150k MAGI), vehicle loan interest up to $10,000 (phasing out at $100k/$200k), and tip/overtime relief.
And let's talk about that new senior deduction. It's a game-changer for folks 65 and older by year's end. You can claim $6,000 per qualifying individual ($12,000 if both spouses qualify on a joint return), and it's available whether you itemize or not. Just make sure to include the SSN of the qualifying person. But watch the phaseouts: It starts reducing once modified AGI hits $75,000 for singles or $150,000 for joint filers, fully phasing out at higher levels. This above-the-line deduction for 2025-2028 can really help retirees stretch their dollars, so factor it into withholding adjustments now to optimize refunds or avoid owing.

Keep an eye on QuickAlerts and the MeF Operational Status page for the final dates and times. If you still have 2024 returns trickling in, now is the time to warn clients that “e-file may not be available” soon and that paper filing might be the only option if they keep waiting.

Tax planning isn't just December - keep it going with simple habits like withholding tweaks, record organization, and Roth considerations. IRS tools make estimates a breeze.
Here are some key tips from the IRS:

• Organize tax records: Create a system using software or labeled folders to store documents as received, simplifying return preparation and helping identify overlooked deductions or credits.
• Identify filing status: Determine the best filing status based on circumstances like marriage or divorce, using IRS tools, to affect deductions, credits, and tax amounts.
• Understand adjusted gross income (AGI): Track AGI (income minus adjustments) to recognize that higher AGI increases tax rates; make year-round changes to lower it.
• Check withholding: Use the IRS Withholding Estimator to ensure sufficient tax is withheld from pay, updating Form W-4 with employer if financial situations change.
• Make address and name changes: Notify IRS via Form 8822, employers, and Social Security Administration of changes to ease tax return filing.
• Save for retirement: Contribute to workplace retirement plans or traditional IRAs to reduce AGI and taxable income.
