1099-SA MULTIPLE ACCOUNT PROCESSING WORKSHEET Use this checklist to verify system logic for recipients holding multiple accounts. TIN CONSOLIDATION CHECK: [ ] System identifies all active and closed accounts linked to a single TIN. [ ] System isolates accounts by plan type (HSA, Archer MSA, MA MSA). DISTRIBUTION EXCLUSIONS: [ ] Internal and external trustee-to-trustee transfers are flagged and excluded from Box 1. [ ] Reversals of mistaken distributions (if permitted by policy) are zeroed out or excluded. [ ] Closed account zero-out transfers are verified as non-reportable movements. FORM GENERATION CONTROLS: [ ] Separate 1099-SA generated for each distinct plan type. [ ] Unique Account Number assigned and printed on every form for TINs with multiple forms. [ ] Box 5 correctly checked matching the specific account's plan type. FURNISHING AND DATA SECURITY: [ ] Recipient TIN is truncated appropriately on the payee statement (Copy B). [ ] Trustee/Payer TIN is fully visible on all copies. [ ] Un-truncated Recipient TIN is used on the IRS filing file. CORRECTION ROUTING: [ ] Correction logic requires the original Account Number to override previously submitted files. [ ] Corrected files follow the channel formatting of the original electronic or paper submission. Reviewer Signature: __________________________ Date: _______________
