I graded AI on the 4 places it's supposed to save tax pros time, based on one question: Does it actually save me time after I check its work? Tax research: C+ for generic AI. Moves up to an A when the sources are cited and easy to check. Organizing client data: A-. Saves me 15-20 minutes per project, but I still check every number. Tax planning: D for generic AI. By the time I prompted it enough to get a real idea, I could have worked through the scenarios myself. Return prep: Incomplete. Half my clients have a Schedule C or E, and nothing I've seen can finish a full return without a human in the loop yet. I also put Thomson Reuters' CoCounsel Tax, Ready to Advise, and Ready to Review to the test to see where they outperform generic AI. Thanks to @TRTaxAccounting for sponsoring this one. If you want tax research answers with the citation right there, check out CoCounsel Tax (see link in reply): I also post a tax research prompt for you to use below. What grade would you give AI in your firm?

this might be my last normal tweet before biotech goes vertical i'm not a whistleblower. I don't work at Lilly, Novo or any of the big labs but there is a massive shift happening in human biology right now. it's sitting in press releases and almost nobody reads them the last 6 months alone: - a once-daily pill roughly doubled median survival in metastatic pancreatic cancer (13.2 vs 6.6 months) - a one-time gene editing infusion cut hereditary angioedema attacks 87%, and 62% of patients stayed attack-free and off all other prevention for 6 months - a one-time gene edit for cholesterol dropped LDL up to 62%, and it held for over a year - a personalized mrna vaccine beat keytruda alone in a 1,137 patient melanoma phase 3 - retatrutide hit ~28% weight loss in a phase 3 - an ai-designed drug entered phase 3 - a pill that regrows hair passed its second phase 3 - an immunotherapy that could let some rectal cancer patients skip surgery, chemo and radiation just got fda approved - a man lived 271 days off dialysis on a pig kidney - human cells were caught passing chromosome-sized chunks of DNA to their neighbors, and it changes how the neighbors behave we are on the verge of an era where the human body is a software problem and the update cycle gets shorter everyday stick around, it's going to get weird bio/acc

Strike quality is so underrated. People will work on things that move the needle much less and almost ignore it. And improving your strike quality will self-organize other improvements that matter - like face to path. In The Strike Plan, I go through all the drills you need to see quick improvements, while sowing the seeds for long-term gains too. Learn more here - adamyounggolf.com/the-strike…

4 small accounting firms. Real AI workflows: One Stop CPA paired Blue J tax research with ChatGPT Enterprise to turn complex multi-state M&A questions into memos in 2 hours instead of days. Agate CPA used Lovable and Claude to build custom website intake forms, boosting conversions by 25% for almost zero cost. Public Trust CPA built a Power Automate + ChatGPT workflow to route vendor invoices straight into QuickBooks with signed docs attached. High Rock Accounting built its own client satisfaction tracker in 5 hours using Claude Code, replacing a paid software tool entirely. These firms picked one annoying, repetitive task and automated it: youtube.com/live/G2xfT5RT9i0…

To my fellow #TaxTwitter compatriots: The October 15th offensive has officially ended. We’ve survived on caffeine, rage, and an unreasonable amount of profanity. Today, we emerge from our bunkers and reacquaint ourselves with sunlight.

EY is paying employees up to $25,000 to catch their own AI's mistakes. They’re calling it a bonus for "human checks". But let's call it what it is: a bounty program for AI slop. This comes right after all four Big Four firms faced major incidents involving fabricated AI citations in their consulting divisions. We talk about it on Episode 504 of The Accounting Podcast: youtube.com/live/s2wn65xfdsE…

Incredible change for one of my students here Before - Left image After - Right image Now, I'll be up front with you... This is at about 25% speed. BUT, It shows me he understands the feel, the look, the movement that we are looking to move towards When I'm working with players, If we are working on a change, you MUST show me you can perform the movement down speed. If you can't do it slow, you most definitely won't be able to do it fast Now I know he can do the movement, we can now focus on ramping up the speed Learning new techniques is important, but learning "how to learn" is important too, & most golfers have no idea how to learn a new motor pattern If you want to learn, DM me & let's get started with a program 👊

Michael Jordan talks to Steph Curry about his golf obsession. Pro athletes are figuring this out. Many used to be lost after retirement, but now they take up golf and the competitive fires are quenched. MJ conquered basketball. But he can’t beat golf.

But simply making the line longer, which you can now do because of the bigger mallet head, and it's easier to see the crooked one.

My wife and I own Forest Park Pharmacy, and we don't accept insurance. None of it. That decision is exactly why we could fix what happened to a patient today. A family came in wanting to transfer their kid's antibiotic to us. The child had already STARTED the course. Then, mid-treatment, the insurance company decided the last 14 tablets suddenly needed a "prior authorization" before the other pharmacy could hand them over. A sick kid, halfway through an antibiotic, and the answer was "please hold." The drug is linezolid. It's a generic. It's been generic for over a decade. It treats serious gram-positive infections — the kind you do NOT want to stop antibiotics in the middle of, because an interrupted course is how you breed resistant bugs and end up right back where you started. So why the hold-up on a cheap, common generic? Follow the fake math. Insurance and the PBMs behind them price drugs off a number called AWP — "Average Wholesale Price." People in my industry have another name for it: "Ain't What's Paid." It's a benchmark number, not a real-world cost. On paper, the AWP for just those last 14 tablets is about $2,500. My cash price for the same 14 tablets? $18. Read that again. The system that's supposedly "protecting" this family from cost is the same system that inflated an $18 medication into a $2,500 line item, then slapped a prior auth on it to "review the expense" THEY invented. They manufactured the problem, then billed everyone for the privilege of solving it — and made a sick kid wait while they did it. This is the whole game. When a drug is priced honestly, there's nothing to "manage." When it's priced off a fantasy benchmark, you get spread pricing, PA paperwork, pharmacy phone trees, and delayed treatment — all dressed up as cost control. Here's the part nobody tells you: roughly 90% of prescriptions are low-cost generics. For the vast majority of what people pick up every day, running it through insurance does two things — raises the real cost and risks delaying your care. That's it. That's the value-add. That's why we fired the insurance companies. No middleman deciding your kid can't finish their antibiotics on schedule. No fake prices. Just the real number, on the shelf, today. The medication was always cheap. The insurance was the expensive part.

AI is having its moment in the accounting and tax world. I love It and am here for it, but arguably the bigger conversation is the one happening around it: Section 7216, client confidentiality, and the rest of the regulatory considerations. The unfortunate truth is that no clear-cut guidance exists today. AI is new, and a lot of the existing regulatory framework simply hasn't been updated to address it fully. Which is exactly why I'm excited to announce that I'm joining Rebecca (@RDriscollCPA) and Michael (@michaelcutajar ) at the AI Lab for Accountants (ailabforaccountants.com). I share their mission, which is to build a community of AI-native accountants and tax pros who leverage AI safely, responsibly, and appropriately. Not only to give us back some of our time as professionals, but to elevate the service we provide to our clients. The AI Lab is meant to be a place where accountants, wherever they are in their AI journey, can come to learn, grow, and develop. While also empowering them to use these tools, vet them, and build the confidence to use them well, even though the regulatory guidance hasn't caught up yet But it's important to be honest: we don't have all the answers, and we'll never claim to. What we're doing is working hard to fill the gap that exists today. We're constantly reaching out to the people inside the regulatory bodies, the IRS, the AICPA, and our own state societies, urging them to address AI more clearly so the rest of us can use it confidently and appropriately in our work. We just released our newest tool, the Safe Use Planner. We took everything we've learned so far and built it into something that helps you navigate using AI safely and get your firm set up to do it right: safe-use-planner.ailabforacc… To be clear about what we are building: a place to learn and develop, not a source of truth or law. Filling that gap isn't ours to do, but we feel it's our duty to do everything we can to help close it. We're revamping the AI Lab for Accountants site to reflect this mission, and there's much more coming. If you're trying to become an AI-native accountant, come join us for the journey. It's going to be a lot of fun.

This is the easiest way to show you the simplified MATCHUP between body rotation & shaft pitch. The steeper you are, the more you have to tilt in order to get the club back in position. If you try rotating instead, you’ll get way too steep on it. The shallower you are, the more you need to rotate in order to get the club back into position. If you try tilting, you’ll get stuck way underneath and will suffer from all sorts of low point and contact issues. This is a big reason why being shallower is specifically better for golfers who want to rotate more through the shot. Enjoy! 🤙
