How US Accountants Run Windows-Only Software on a Mac
If you’re an accountant on a Mac, you’ve already noticed the gap. Most of the software the accounting profession runs on was built for Windows, and many of those tools never got Mac versions.
This isn’t true of everything - Xero, FreshBooks, and Wave are cloud-based and work from any browser. But the tax software, the professional accounting suites, the industry-standard tools that larger firms standardize on - most of them are Windows.
Here’s a rundown of what accountants commonly need, where the Mac gap is, and how Parallels closes it.
Tax Software (US Individual and Business Filing)
Drake Tax: Windows-only. Drake is one of the most widely used professional tax software packages among US CPAs. No Mac version exists. Runs in Parallels.
UltraTax CS (Thomson Reuters): Windows-only. Enterprise tax software used by mid and large CPA firms. Runs in Parallels.
Lacerte (Intuit): Windows-only. Professional tax software for high-complexity returns. Runs in Parallels.
ProConnect (Intuit): Web-based. Works on Mac without Parallels.
TaxAct Professional: Has a web-based version. The desktop software is Windows-only and runs in Parallels.
ATX Tax Software (Wolters Kluwer): Windows-only. Runs in Parallels.
CCH Axcess Tax (Wolters Kluwer): Web-based for the main filing workflow. Desktop tools for firm management may require Windows.
Verdict: For professional tax filing in the US, Drake and UltraTax are the most common - both Windows-only, both run well in Parallels.

The Parallels Setup for an Accountant
Hardware: MacBook Pro with M3 or M4, 32 GB RAM is ideal. During tax season when you’re running multiple software packages simultaneously, more RAM matters.
VM Configuration:
- Memory: 12 - 16 GB (during tax season, lean toward more)
- CPU: 4 cores
- Storage: 120 GB+ (Drake or UltraTax installations are large, and client files accumulate)
Print and PDF: Printing from accounting software in Parallels to a Mac printer works. PDF printers (saving as PDF from Windows) work through Parallels’ printer sharing. Mac printers appear in Windows printer selection automatically.
Backup: Your client files may live inside the Windows VM’s storage. Back up the entire VM using Time Machine on the Mac, or use Parallels’ backup integration with Time Machine. More importantly, follow your firm’s client data backup policy - usually this means files are on a network server or cloud storage, not just on one machine.
