Iristurn
An IRIS migration workbench for accounting firms that sequences transmitter registration, validates contractor and information-return data against effective schemas and rule versions, rehearses the first filing, and preserves staff approval, agency acknowledgment, acceptance, rejection, and correction as separate states.
The supplied IRS evidence targets Tax Year 2026 and Filing Season 2027 for FIRE retirement, with IRIS as the only intake system, while transmitter credentials may require a long lead time and application-to-application filing adds a separate developer credential. Iristurn turns that transition into a controlled migration: readiness inventory, credential workflow, schema validation, effective rule pack, sandbox rehearsal, approved transmission, acknowledgment reconciliation, and correction. Credential application is not issuance, validation is not filing, transmission is not agency receipt, receipt is not acceptance, and acceptance is not proof that payee data, tax treatment, payment, withholding, delivery, or correction is substantively right.
An owner, tax-information-reporting lead, operations manager, or systems lead at an accounting firm or agency managing repeated contractor and information-return filings for multiple clients.
Official evidence targets the Tax Year 2026 and Filing Season 2027 transition, and credential processing requires early action.
Accounting-firm owners and information-reporting operations leads are specific and face repeated multi-client migration work.
Two cross-references, one inbound connection, and one direct connection provide moderate corroboration while the grounded score remains five.
Two cross-references, one inbound and one direct link, an official targeted retirement date, a long credential lead time, a separate developer-credential requirement, an identified accounting-firm buyer, and no dedicated migration micro-product in the supplied scan create a concrete dated wedge.
The retirement date is described as targeted rather than an immutable guarantee, official schemas and tax rules can change, filing authority and client data are sensitive, commercial filing APIs already exist, support is seasonal, and the input does not validate acquisition or product pricing.
