Tax software server readiness starts with the exact vendor requirements, then adds the capacity your firm needs for real simultaneous work. A machine meeting a published minimum is not automatically sized for every preparer, tax application, document tool, and retained filing year.
For the 2027 filing season, distinguish the filing year from the product year. Drake Tax 2026 and ProSeries tax year 2026 are examples of software used to prepare 2026 returns during the following filing season.
Key takeaways
- Match requirements to the exact application year, edition and deployment.
- Keep vendor minimums separate from recommended capacity and the firm’s actual peak load.
- Read workstation, file-server and remote-session guidance separately.
- Test printing, integrations, remote access and recovery alongside return preparation.
- Compare repair, replacement and hosting using the full support and licensing responsibilities.

Start with a vendor requirements comparison
The snapshot below was checked on Oct 9, 2026. Requirements can change; use the linked vendor guidance again before purchasing or migrating.
| Product / scope | Operating system guidance | Published memory / capacity | Source / checked |
| Drake Tax 2026 | Windows 11; Server 2019, 2022 or 2025. ARM unsupported. | 8 GB RAM minimum; 16 GB recommended. 4 GB base disk minimum; actual needs vary. | Drake 2026 requirements; |
| UltraTax CS / general product guidance | Windows 11; Server 2016, 2019, 2022 or 2025. Check separate Terminal Server guidance. | 4 GB RAM minimum; 8 GB+ recommended. 2.25 GB for modules; data needs vary. | Thomson Reuters general requirements; |
| ProSeries Professional / Basic, tax year 2026 | Windows 11 desktop guidance; recommended file-server list includes Server 2019 and 2022. | 8 GB RAM minimum; 8 GB+ recommended. Network file server: 8 GB minimum. Test actual load. | Intuit tax year 2026 requirements; |
Read desktop, file-server, and multi-user guidance separately. A published workstation memory figure is not a universal hosted-server allocation.
The source pages are Drake’s 2026 requirements, UltraTax CS system requirements, and Intuit’s ProSeries tax year 2026 requirements. Confirm the edition and deployment with the vendor or the appropriate support team.
Check 1: Operating system and deployment
Inventory the operating system, edition, version, processor architecture, and support lifecycle for the server and relevant workstations. Confirm whether the application supports the planned arrangement, including a file server or remote session environment.
For ProSeries, Intuit explicitly states that terminal-server environments and network-attached storage are unsupported. A supported file-server operating system does not establish support for running ProSeries in remote sessions. Confirm the exact hosting arrangement and publisher support before committing to a deployment.
Do not assume a program that launches is in a supported configuration. Installation, printing, e-filing, integrations, and multi-user behavior may have separate requirements.
UltraTax’s general guidance also points to additional Terminal Server recommendations. Use those when evaluating remote sessions rather than applying the desktop minimum to every user.
Check 2: Memory and processor headroom at the firm’s actual peak
Measure the environment while staff perform representative work. Include the applications they open together and the busiest plausible number of concurrent users.
Record memory use, CPU pressure, response times, and signs of swapping or contention. A single-user test can miss a bottleneck that appears only when several preparers calculate returns and handle documents together.
Separate the vendor’s minimum from a practical sizing recommendation. For example, Drake’s 2026 sheet lists 8 GB RAM as a minimum and 16 GB in its optimal-performance recommendations. That distinction matters when explaining whether a machine fails a requirement or merely lacks desired headroom.
Check 3: Storage growth and application dependencies
List the current-year installation, retained prior-year applications, client files, document storage, temporary work, and backup needs.
A vendor’s installation-space figure does not represent the entire firm’s storage requirement. Review actual growth and leave room for updates and peak-season operations.
Confirm dependencies such as required runtimes, browser components, PDF tools, and Office integrations. Test printers and scanners using representative output, not just a successful application launch.
Before moving, identify data paths and integrations that depend on a particular local drive or server name.
Check 4: Network and remote access
Test from the office and the remote locations staff actually use. Review latency, stability, upload capacity, and simultaneous workloads as well as the headline download speed.
Drake’s recommended connection figure is a product recommendation, not proof that every firm with that connection will have a satisfactory remote experience.
For UltraTax remote access or ProSeries hosting on cloud infrastructure, test document movement, printing, and session behavior alongside return preparation. Confirm how authentication and authorized access are configured.
Check 5: A recovery test the firm can explain
Choose a controlled test with synthetic or appropriately protected data. Restore the files and application components needed to resume an agreed workflow.
Record the recovery point achieved, the time taken, any missing dependencies, and the person who approves the result. Restoring one file proves a narrower capability than recovering the full environment.
Ask who can initiate recovery if the usual administrator is unavailable. Confirm that backup access is controlled separately and that the agreed retention matches the firm’s needs.
Should you repair, replace, or use tax software hosting?
Repair can make sense when the platform is supported and a defined upgrade resolves a measured bottleneck. Replacement may be appropriate when hardware or operating-system limitations make the existing environment difficult to support.
Tax software hosting is another option when the firm wants a managed application environment and remote access. Compare total responsibilities: licenses, migration, integrations, user permissions, updates, backup arrangements, local devices, and provider support.
Avoid deciding from a per-user price alone. Confirm the proposed resource allocation and test the firm’s representative workload before acceptance.
“Verito came to our rescue when our software hosted directly at Drake failed and we could not access our files. We were back up in less than an hour.”
Raven Pyle-McCrackyn · Google, Dec 2025
What should go into the firm’s readiness sign-off?
Keep a short record of the application versions, source requirements, proposed configuration, measured peak workload and completed workflow tests. Add unresolved dependencies, the person responsible and the evidence needed to close each item.
Set acceptance criteria before purchasing or migrating. A system is ready when the agreed tasks work under the intended load and the recovery test meets the firm’s needs, rather than simply because every application opens once.
How Verito helps with application-specific hosting
Use Drake cloud hosting for a Drake deployment discussion, UltraTax hosting and remote access for an UltraTax workflow, and ProSeries hosting for ProSeries requirements.
VeritSpace hosting provides a dedicated application environment. Ask Verito to document the proposed setup, migration checks, responsibilities, and recovery arrangements for your firm.
Software licensing and the publisher’s support policy remain separate questions. In particular, Intuit’s published ProSeries guidance excludes terminal-server environments. Ask Verito and Intuit to establish whether the proposed ProSeries arrangement is supported before proceeding. A third-party hosting offer is not evidence of publisher authorization or endorsement.
“Verito is my first cloud experience. It has been a very easy transfer.”
