Lacerte Support for CPA Firms: Hosting, Remote Access, and Tax-Season Speed

Lacerte support comes from two places. Intuit supports the software: the program, its forms and calculations, e-file questions, licensing and renewals, and its own hosted version of Lacerte. Your firm, usually through its IT provider, supports everything the software runs on: the server, the network, remote access, antivirus settings and backups. Intuit's help articles draw that line themselves, down to stating that Intuit does not keep an off-site backup of your Lacerte data. The IT half is also what decides how fast Lacerte runs in March.

What Intuit's Lacerte support covers#

Call Intuit when the question is about the software itself: a calculation that looks wrong, a form or diagnostic, an e-file rejection, a program error after an update, or your license, renewal and Fast Path seats. Intuit's How to contact Lacerte for help (opens in a new tab) page lists 1-800-933-9999 for support and renewals, and posts current hours there, including deadline hours. Its Lacerte FAQ (opens in a new tab) says toll-free technical support is typically available 6 a.m. to 5 p.m. Pacific (8 a.m. to 7 p.m. Central), Monday through Friday, with extended hours during tax season, including weekends.

Intuit also offers Hosting for Lacerte, which its hosting FAQ (opens in a new tab) says is provided through an exclusive partnership with Rightworks. If you are hosted, the server moves to them.

What an IT provider handles for Lacerte#

Intuit's own articles hand these jobs to you. Its Lacerte system requirements (opens in a new tab) page says Lacerte Support "won't be able to assist you with configuring a backup software" or with "adding exclusions in your security software," and points you to your IT person for both. Its common settings for Lacerte system administrators (opens in a new tab) article says network changes "should only be made by IT personnel" and that "Lacerte support agents will not perform these changes."

In practice, good Lacerte support from an IT provider covers:

• The server. A supported Windows Server version, enough memory, shares set the way Intuit documents, and patching scheduled away from deadline weeks. Our managed server support covers monitoring, patching and backup verification for servers like this one.
• The network. Gigabit switches, network cards configured per Intuit's guidance, and drive mappings that do not drop.
• Security software. Antivirus exclusions for the Lacerte folders, and a firewall that allows the ports and web addresses Intuit lists in its firewall and antivirus configuration article (opens in a new tab).
• Backups. A scheduled, tested backup and disaster recovery plan for Lacerte client data, program options and DMS documents, stored in more than one place.
• Remote access. A setup that stays fast with every preparer logged in, and requires multi-factor authentication.
• Workstations and scanners. Windows 11 PCs with enough memory, and TWAIN scanner drivers for Lacerte DMS.

Most of that list is the same work the rest of your practice needs, so treat Lacerte as one part of your accounting firm IT, not a separate project.

Who to call#

Why is Lacerte slow on our network?#

In an office install, Lacerte reads client data across your network, so a slow network shows up as lag while preparers type. Intuit publishes the numbers:

• The system requirements list a minimum LAN speed of 50 MB/sec and recommend 1-gigabit network switches.
• The system administrator article says "Lacerte performs slowly if network speeds go below 20MB/s" and recommends disabling Large Send Offload on every network card, including the server's.
• Intuit's slow performance article (opens in a new tab) gives a simple test: copy the SetupYY folder from the server to a workstation's desktop and watch the speed Windows reports. Intuit says it should be 30 to 60 MB per second or more. Well under 30 means the network is part of the problem.

Intuit's articles also name the setups that cause trouble, and all of them sit on the office side:

• Antivirus or backup software scanning the Lacerte folders in real time. Intuit recommends backups that run on a schedule, not continuously.
• Offline Files or Sync Center turned on for the Lacerte share.
• Data stored on a NAS drive, which Intuit does not support.
• Data in Dropbox, Google Drive or OneDrive. Intuit says file share and sync services "aren't supported for data storage, backup, or sharing purposes."

Lacerte remote access that holds up in tax season#

A remote setup that feels fine in August can fall over when several preparers log in at once in March. There are three patterns that work and one to avoid.

Hosting for Lacerte#

Intuit's hosted option runs Lacerte on Rightworks servers, and your staff connect over the internet. Per the hosting FAQ, hosted data is backed up nightly with a rolling 90 days kept, Lacerte updates automatically, and the last 10 years of the software can be hosted. Concurrent users need Fast Path licenses. Without them, hosting allows one user per session, so count your busiest day before you buy seats.

Hosting moves the server out of your office. It does not remove the rest of the IT work: your PCs, internet connection, printers, scanners, email security and staff logins still need someone.

Your own Remote Desktop or Citrix server#

Intuit lists Windows Remote Desktop Service and Citrix as supported environments "on a supported file server OS with at least 2GB RAM/user," and publishes an administrator's guide to installing Lacerte on Citrix or a terminal server (opens in a new tab). Lacerte runs next to its data, so the program gets office network speed even when the preparer is at home. You also own the server, the Microsoft licensing that goes with it, and the patching.

Remote control of an office PC#

For one or two remote preparers, connecting to their own office PC through a gateway or remote support tool with multi-factor authentication keeps Lacerte on the office network. The PC has to stay on and awake, so power settings and Windows updates need managing or it will be asleep the night before a deadline.

What to avoid: a VPN and a mapped drive#

The tempting setup is a VPN from a home laptop to the office share, with Lacerte running on the laptop. Do the math on Intuit's slow line: 20 megabytes per second (the unit Windows shows when copying files) is 160 megabits per second (the unit internet plans are sold in), sustained. A VPN can go no faster than the slower of your office upload and the preparer's home download. If your office upload is below 160 megabits per second, that preparer starts under Intuit's slow line before Wi-Fi is even counted. Use the VPN to reach a Remote Desktop server or an office PC instead, so Lacerte runs next to its data.

Whichever you choose, lock it down#

CISA's ransomware guide (opens in a new tab) says "Do not expose services, such as remote desktop protocol, on the web," and, for systems that do use RDP, to apply multifactor authentication. For tax firms there is a rule behind that advice too. The FTC lists tax preparation firms among the businesses its Safeguards Rule covers, and its Safeguards Rule guidance (opens in a new tab) says to "implement multi-factor authentication for anyone accessing customer information on your system." Your written information security plan should describe how remote access works. This is general information, not legal advice.

Pre-season Lacerte checklist#

Intuit's FAQ says the new Lacerte program is typically released for download in November, so run this before it goes on your server. When we checked in September 2026, Intuit's requirements page covered tax year 2025. Recheck it when the next version posts.

1. Check the server's Windows version. For tax year 2025, Intuit lists Windows Server 2016, 2019 and 2022 for file servers. Windows Server 2025 was not on that list as of September 2026, so check before you buy a new server. Microsoft's Windows Server 2016 lifecycle page (opens in a new tab) shows extended support ending in January 2027, and Intuit's FAQ says that when Microsoft sunsets an operating system, Lacerte discontinues support. A 2016 server is a plan-now item, not a March surprise.
2. Check every workstation. For tax year 2025, Intuit lists only Windows 11 for workstations, and its requirements page notes that Windows 10 stopped getting free security updates after October 14, 2025, unless you subscribe to Microsoft's Extended Security Updates program. The memory minimum is 12 GB, with 16 GB recommended.
3. Run the copy test from each workstation and write down the speeds.
4. Confirm antivirus exclusions and firewall rules against Intuit's current article, including the Lacerte folders and DMS.exe.
5. Set backups to a schedule and stop real-time backup scanning of the Lacerte folders.
6. Test a restore. Restore one client file and one DMS document to a test location. Intuit's backup guidance: back up more often than the amount of work you can afford to lose, and keep several previous backups instead of overwriting one.
7. Test remote access for every remote preparer from where they will actually work, with multi-factor authentication on.
8. Match Fast Path seats to your real peak of simultaneous users if you are hosted.
9. Check DMS scanners. Intuit requires a TWAIN-compliant driver and says Neat scanners aren't compatible with DMS.
10. Update your security plan so it describes the setup you actually have.
11. Post the numbers. Intuit's Lacerte line (1-800-933-9999; hosted users say "Hosted") and your IT provider's number, somewhere the office manager can find them.
