Every year, thousands of businesses receive B-Notices and face penalties because of invalid or mismatched TIN/Name combinations. If a payee’s Name/TIN doesn’t match IRS records, the IRS may send a CP2100/CP2100A ‘B-Notice,’ which can require you to begin backup withholding on future payments.

See how lenders, marketplaces, HR teams, and compliance leaders use Compliancely to move faster with confidence.
“We moved to Compliancely because our team was stuck in a verification limbo. Now KYC and TIN checks can be done instantly. Everything logs cleanly for audits, and manual reviews have dropped more than we thought possible. With B-Notices and mismatches way down, we finally have the breathing room to focus on real credit decisions.”
“We'd flag legitimate businesses left and right, and our queue was a always nightmare. Then we switched to Compliancely's combined KYB and sanctions screening. It’s been a game changer. Pass rates went way up, false alarms went way down, and we can check everything in one place now”
“It’s the cleanest vendor onboarding flow we’ve had. Usually, setting up new vendors used to be this endless nightmare. So. Much. Back-and-forth. But now Compliancely is making it much easier to get TIN, SoS, and address checks together. This is the first time our vendor setup process has felt simple.”
“Compliancely’s ongoing monitoring has been invaluable to my team. It flags risk changes the moment they happen, sanctions, account status, all of it. We’re catching issues before money moves, and it shows. Our SARs quality is better, and audits have gone noticeably smoother often before a transaction is even initiated. It feels like adding an extra layer of protection to every workflow.”
“Compliancely alone has changed how we work. It can pull transcripts in minutes. So now the back-and-forth with clients that was once the case, has practically disappeared. Its built-in analysis and risk insights have also helped us get ahead of issues instead of discovering them late in the prep cycle.”
“Compliancely has been one of the most impactful changes we’ve made to our HR stack. We have been using it to verify I-9 eligibility, run employee identity checks, and validate addresses. New hires are moving through onboarding so much faster now. Our candidates are happier because they're not waiting around forever, and I'm happier because I'm not drowning in paperwork. Win-win all around.”
