| Component | Implementation | | :--- | :--- | | | Microsoft Hyper-V or VMware ESXi | | Operating System | Windows Server (2019/2022) with Desktop Experience | | Database | Local SQL Express (bundled with ATX) or full SQL Server | | Protocol | RDP (Remote Desktop Protocol) over TLS 1.2+ | | Multi-User Access | Windows Server CALs or user-profile isolation | | Printing | Redirected local printers or cloud-based print solution |

Conclusion: Near cost parity, but cloud offers mobility and eliminates capital expenditure. Hosting ATX tax software in a managed cloud environment is a mature, secure strategy that solves remote access, disaster recovery, and collaboration challenges. While not a native SaaS product, session-based RDP hosting provides a superior user experience compared to VPNs or peer-to-peer networks. Firms should prioritize providers with explicit ATX support, SOC compliance, and seasonal scalability. As tax preparers increasingly work hybrid schedules, cloud-hosted ATX becomes not just an option but a competitive necessity. Disclaimer: This paper is for informational purposes.
