Over the past few months, our MMB+CO Team has unpacked everything OBBBA- from SALT and PTET to bonus depreciation and R&E credits. Now it’s time to connect the dots. 💬Read Kurt's thoughts below on how these pieces come together to shape strategic tax planning for businesses. #MMBandCO #OBBB #TaxStrategy #ThoughtLeadership #PlanningAhead
As I wrap up MMB+CO's OBBB series, one thing stands out: this law rewards those who plan ahead. Over the past few months, my colleagues and I have explored everything from SALT and PTET to bonus depreciation and R&E credits. Now, it’s about connecting the dots. For individuals, higher SALT caps, expanded credits, and permanent estate tax relief create real opportunities. For businesses, 100% bonus depreciation, a permanent QBI deduction, and renewed R&E expensing can drive growth—but only with the right timing. The OBBB isn’t just a tax bill—it’s a roadmap. Acting now can turn complexity into advantage. Read my full Rochester Business Journal article HERE: https://lnkd.in/eUNC677M #TaxReform #MMBandCO #CPAInsights #OneBigBeautifulBill MMB+CO

Last week our Elmira Office proudly participated in the Leader of the Pack Corporate Challenge to support the Food Bank of the Southern Tier! Our team of ten went head-to-head with eight other local businesses to see who could pack the most bags for the Backpack Program — and the fastest! While we didn’t take first place, we had a fantastic time working together for a meaningful cause. We’re proud to support our community and grateful for the opportunity to make a difference. #TeamMMB #MMBandCO #LeaderofthePack

Big news for businesses: the latest IRS guidance (Rev. Proc. 2025-28) makes it easier to take advantage of research & experimentation tax incentives. Thanks to the One Big Beautiful Bill, you can now fully deduct domestic research expenses right away—or spread them out over time. Some small businesses can even retroactively claim refunds (just remember, timing and documentation matter). And these benefits aren’t just for big research labs. If you’re building prototypes, developing software, improving processes, or experimenting with new packaging, you could qualify for immediate tax savings. If you’re designing, testing, or improving, now’s the time to revisit your strategy. At MMB+CO, we’re here to help you make the most of these new rules. Curious how this could help your business grow?
