Solo & small-firm CPAs and EAs — what’s the multi-state deadline moment that nagged at you?

Hey all — apologies for the ask while everyone's still catching their breath!

Writing specifically to the solo and small-firm CPAs and EAs here — owners, founders, and partners at 1-to-5-person practices handling your own multi-state caseload. What was that one moment from this season that's stuck with you (near-miss, state announcement that blindsided you, weekly triage that ate your morning…)

and what you actually use to stay on top of it all? Especially interested if you handle 20+ SMB clients across multiple states — that's the shape of practice I'm trying to understand best. I'll post a follow-up here with patterns across everyone who replies — tools that came up repeatedly, workarounds for the state-announcement problem, near-miss stories worth learning from.

Thanks

G
