Drake Tax at $1,695/year for unlimited returns is the best value in professional tax software. For a practice with 150 returns at $400 average, Drake costs $11.30 per return. Lacerte at $5,000/year for 150 returns costs $33.33 per return — nearly 3x more. The difference: Drake has a less polished UI and fewer advisory features. But for a practice focused on efficient return preparation, Drake is hard to beat. Most practitioners who switch to Drake from Lacerte or ProSeries report that they miss the UI but not the price.
Tax Software Best Practices
| Best Practice | Why It Matters | How to Implement |
|---|---|---|
| Update software before tax season | Software updates fix bugs; add new forms; update for law changes | Update by January 1; test with a sample return before first real e-file |
| Use the diagnostic review | Diagnostics catch errors before e-filing | Run diagnostics on every return; investigate every error and warning |
| Use the organizer feature | Organizers help clients gather documents | Send organizers in December; customize for each client type |
| Use the comparison feature | Year-over-year comparison catches anomalies | Review comparison for every return; investigate significant changes |
| Back up your data daily | Data loss is catastrophic | Use cloud backup (Drake Cloud, Lacerte Cloud) or external drive backup |
| Use e-signatures | E-signatures speed up the signing process | Use DocuSign, Adobe Sign, or built-in e-signature features |
| Reconcile to prior year | Prior year data prevents errors | Import prior year data; verify carryforward items |

Background: Andrew M., EA, had a 120-client practice and was paying $4,800/year for ProSeries. He switched to Drake in 2023. Results: (1) Software cost reduced from $4,800 to $1,695 — saving $3,105/year; (2) Return preparation time reduced by 15% (Drake's keyboard-driven interface is faster for experienced users); (3) Support quality improved; (4) No features lost that Andrew actually used. Total annual savings: $3,105 in software cost + 15% time savings on 120 returns × 3 hours average × $200/hour = $10,800 in recovered time. Total benefit: $13,905/year.
Frequently Asked Questions
Drake Tax ($1,695/year for unlimited returns) is the best value for solo practitioners. It is reliable, fast, has excellent support, and costs significantly less than Lacerte or ProSeries. TaxSlayer Pro ($1,495/year) is a good budget alternative for practices with simpler returns.
Drake Tax is a desktop-based software with a keyboard-driven interface — it is fast and efficient but has an older UI. Lacerte is a more polished, feature-rich software with better integration with the Intuit ecosystem (QuickBooks, ProConnect). Lacerte costs 2–4x more than Drake. For most solo and small practices, Drake provides 90% of Lacerte's functionality at 30% of the cost.
Cloud-based software (CCH Axcess, TaxSlayer Pro, TaxAct Professional) offers the advantage of remote access and automatic updates — but can be slower and more expensive. Desktop software (Drake, Lacerte, ProSeries) is generally faster and more reliable — but requires local installation and manual updates. For practices with remote staff or multiple locations, cloud-based software is worth the premium.
Most tax software vendors offer data conversion services. Drake, Lacerte, and ProSeries all support importing prior-year data from competing software. The conversion is not always perfect — verify all carryforward items (NOLs, depreciation schedules, basis) after conversion. Plan the switch for the off-season (May–September) to allow time for testing before the next tax season.
If you discover that a software error caused an incorrect return: (1) Contact the software vendor immediately to confirm the error and get guidance; (2) Determine which clients are affected; (3) Prepare amended returns (Form 1040-X) for all affected clients; (4) Notify affected clients promptly; (5) File amended returns as quickly as possible; (6) Document everything for your professional liability insurer.
