Comparison Table
TaxAct Professional
SMBProfessional tax preparation software for individual and business returns.
Return locking plus preparer sign-off keeps draft, review, and final versions from colliding during multi-preparer work.
TaxAct Professional generates practice returns with a guided preparation flow, built around common IRS and state form work. It includes a form library that supports standard schedules, diagnostic-style guidance during preparation, and e-file transmission steps with acknowledgment handling.
The workflow supports firm-style return management features like return locking and preparer sign-off so reviews and revisions stay controlled. Stronger value shows up when firms need repeatable preparation steps and consistent state package conformance across a batch of engagements.
- +Return locking reduces mid-review edits during a preparer hierarchy workflow
- +Built-in e-file transmission flow includes acknowledgment processing for completion tracking
- +Guided diagnostic prompts surface common data issues during preparation
- +Form library coverage supports routine schedules for recurring client types
- –K-1 import experience can require manual cleanup for partner-level edge cases
- –Batch workflows feel limited compared with systems built for high-throughput return processing
- –State package conformance checks are less granular than tools with deeper per-form conformance controls
- –Client portal exchange features may not cover every firm-specific document routing pattern

Structured estate and fiduciary packages
Preparers assemble fiduciary and estate workflows with traceable calculations for related estate tax forms.
Best for: Fits when a tax firm needs controlled preparer sign-off with return locking and consistent guided preparation.
Lacerte
enterpriseDesktop and hosted professional tax software for complex returns.
Firm workflow controls that combine return locking with preparer hierarchy sign-off and review notes.
Lacerte supports a standard practice return lifecycle with organizer import, tax year carryforward handling, and a return comparison view for prior-year changes. The form library and schedule support cover common business and individual needs, and the software enforces field-level logic while driving data entry through diagnostic checks. E-signature routing and preparer sign-off workflows support controlled completion inside a firm hierarchy.
A notable tradeoff is that Lacerte’s extensibility and automation surface is less obvious than practice workflow tools that integrate through broad APIs. Lacerte fits firms that prioritize reliable return production with built-in diagnostics, especially when the team needs consistent review notes, return locking, and rejection-resolution routines across many entities.
- +Guided return prep with built-in diagnostics and review note handoff
- +Return locking and hierarchy-based preparer sign-off reduce workflow drift
- +Batch e-filing with acknowledgment processing and e-file status visibility
- +Prior-year carryforward and return comparison support repeatable production reviews
- –Automation and extensibility controls are not as visible as workflow-first tools
- –Multi-system data imports can be rigid when inputs do not match the organizer format

Best for: Fits when firms need repeatable return production with diagnostics, controlled sign-off, and batch e-filing.
ProConnect Tax Online
SMBCloud-based professional tax preparation software from Intuit.
Return comparison view that pairs preparer review differences with diagnostic context during the same production cycle.
ProConnect Tax Online fits firms that run repeatable prep and review steps across many individual and business returns, because it emphasizes guided data capture, diagnostic feedback, and standardized output. Organizer import and common document workflows reduce manual typing, while built-in return comparisons and review notes support a second-preparer pass. E-file status dashboards help track acknowledgments and transmission outcomes without leaving the return workspace. The document and transmission workflow is strongest when returns follow the typical input patterns that the organizer and form library expect.
A practical tradeoff is that customization and workflow extensibility are limited compared with products that expose deeper API-first automation and custom data mappings. Firms that need highly tailored due diligence workflows or their own internal data schema for upstream systems often spend more time conforming inputs to ProConnect’s structured fields. ProConnect works best when teams want repeatable production throughput with consistent diagnostics and a review hierarchy that is easy to operate during peak season.
- +Guided interview reduces missing inputs during preparer review
- +Built-in e-file status dashboard improves follow-up on transmissions
- +Organizer import cuts re-keying for recurring client work
- +Return comparison view supports faster reconciliation between versions
- –Workflow customization options are narrower than API-first competitors
- –Some imports require conformity to expected field structures
- –Advanced automation needs more manual orchestration inside the UI
- –Multi-entity consolidation can be slower to verify during review

How to Choose the Right Practice Tax Return Software
Practice tax return software differs most in how it handles scenario work without losing control of results. Prioritize data-entry validation depth and update frequency so your practice returns behave like the real workflow.
Data-entry validation rules
Why it matters
Data-entry validation rules reduce avoidable practice errors that later hide in calculations. For practice tax return software, strong rules also make it clearer what’s wrong before you submit anything.
How to check
Open a sample return and try entering a mismatched value (for example, a wrong relationship between income and deduction fields). Ask the demo to show which field(s) it flags, whether it explains why, and whether it prevents obviously invalid combinations.
Tax form update frequency
Why it matters
Tax form update frequency matters because practice files quickly become outdated and teach the wrong process. In practice tax return software, you need current forms and logic, not just a way to edit old ones.
How to check
Ask what triggers an update and how quickly new versions appear after changes. Then request a tour of version history and confirm that the current tax year forms are available and selectable in the UI.
Scenario and what-if handling
Why it matters
Scenario and what-if handling is what makes practice useful when you vary income, credits, or filing status. The better the support, the less manual cleanup you do between practice runs.
How to check
Create two practice variants from the same client profile and change one major input each time. Check whether the system preserves prior assumptions, keeps comparisons organized, and prevents cross-contamination of results.
Audit trail and change history
Why it matters
Audit trail and change history lets us review training decisions and catch accidental edits. Practice work changes often; without an audit trail, you can’t reliably reconstruct how outcomes were produced.
How to check
In a practice return, make a change and then locate the record of what changed, when, and by whom. Ask if the tool includes a printable or exportable view of change history for review after the exercise.
Practice data import and export
Why it matters
Practice data import and export reduces repetitive typing when you test many scenarios. The faster and cleaner the data model mapping is, the more practice time goes into judgment, not cleanup.
How to check
Bring in sample client data (CSV or spreadsheet) and confirm which fields map automatically. Then export a finished practice return summary and verify you can re-import or reconcile key amounts without missing critical fields.
Return workflow states and controls
Why it matters
Return workflow states and controls help us keep training organized and avoid mixing drafts with final-ready outputs. In practice tax return software, clear states make review exercises repeatable.
How to check
Follow the demo path for creating a draft, moving it to review, and returning to edit. Confirm what actions are allowed in each state (including whether edits are restricted) and whether those states are visible on-screen.
Red flags
- Updates that don’t clearly show current-year forms and calculation logic
- Changes that overwrite earlier practice scenarios without a traceable history
- Imports that map key amounts inconsistently or leave many fields unmapped
Fit by situation
- If you run repeated practice variants from the same client inputs, prioritize scenario and what-if handling.
- If you’re training on current-year requirements, prioritize tax form update frequency.
- If you need to grade practice decisions after review, prioritize audit trail and change history.
