FreeTaxUSA is the best pick for wage-and-1099 consumers preparing a straightforward single return because its diagnostic engine flags omissions and contradictions inside the editor before you submit, whereas ProConnect Tax Online fits tax firms that need repeatable multi-user review controls thanks to its practitioner change tracking with an audit trail.

Comparison Table
FreeTaxUSA
consumerFree federal tax return preparation with low-cost state filing.
Diagnostic engine runs in the return editor to catch omissions and common contradictions before submission.
FreeTaxUSA supports a standard federal return module with a state return module in the same product, so the workflow can stay in one place from entry to e-filing. A built-in diagnostic engine surfaces common errors and missing fields during preparation, and the tax form library is presented in a guided layout instead of a blank form screen. W-2 import and 1099 import reduce rekeying for common wage and contractor income data. The experience is oriented around completing each section in sequence rather than managing multiple linked returns at once.
A key tradeoff is limited depth for complex investor or business workflows compared with paid preparer-focused tools, which can require manual workarounds for edge cases. FreeTaxUSA fits returns where income sources are mostly wages and straightforward 1099s, or where a filer wants quick review cycles driven by on-screen checks. It is also a practical choice for repeat filers who can reuse prior-year carryforward information and want a consistent entry path each season.
- +Guided return flow makes form entry fast to complete
- +W-2 import and 1099 import reduce transcription errors
- +Diagnostic engine flags missing fields before e-filing
- +Federal and state modules stay inside one preparation workflow
- –Weaker coverage for advanced business and investor edge cases
- –Multi-return preparer-style collaboration features are limited

Best for: Fits when wage and 1099 income dominate and a single filer wants guided e-filing checks.
1040.com
consumerOnline tax filing platform developed by Drake Software for individual filers.
Federal-to-state preparation stays coordinated, with the same guided mapping feeding state modules and review checkpoints.
1040.com focuses on guided tax preparation with a structured federal workflow and a form-library driven interview. The product supports document and data imports for common income and deduction sources, then routes entries through review checks and error prevention.
Users can handle multi-entity situations like K-1 related reporting and can prepare state returns alongside the federal package within a single process. Processing includes e-filing readiness checks and audit trail style recordkeeping for preparer visibility during review.
- +Guided interview keeps inputs mapped to the correct federal forms
- +State return module runs inside the same preparation workflow
- +Import-based entry reduces manual keying for common tax documents
- +Built-in review checks surface issues before e-filing submission
- –Workflows for complex schedules can feel slower than direct form editing
- –Multi-user review depends on disciplined document and data handoffs
- –Certain edge-case entries may require manual follow-through when imports omit details
- –Data correction can involve multiple screens because of guided routing

ProConnect Tax Online
professionalCloud-based professional tax preparation software from Intuit.
Practitioner change tracking with an audit trail that maps edits to preparer actions during review.
ProConnect Tax Online is built for tax offices that need repeated preparation steps across many returns, with a preparer workspace that supports collaborative review. E-filing flows connect to practitioner actions like acceptance handling and rejection code resolution, which reduces the time between submission and correction. Standard data ingestion covers common W-2 import and 1099 import patterns, plus prior-year import behavior for carryforward values when the firm maintains recurring clients.
A tradeoff appears in the governance surface, because firms often need disciplined role assignment and internal checklists to keep multi-preparer work from drifting. ProConnect fits best when staff members follow a repeatable intake-to-review process and when the team can standardize diagnostics resolution and document handling across the preparer group.
- +Multi-user review supports controlled handoffs between preparers and reviewers
- +Diagnostic checks tie issues back to specific input conditions
- +Import workflows reduce re-keying for W-2 and 1099 data sources
- +Audit trail records change history for preparer and reviewer activity
- –Role and workflow setup requires firm-wide governance discipline
- –Some complex edge cases demand more manual entry than imports

- +W-2 import and 1099 import reduce manual transcription time for common income
- +Audit trail supports multi-user review with traceable edits
- +Guided form workflow reduces missed dependencies across federal and state modules
- +Carryforward data handling supports recurring tax situations without rework

TaxAct
consumerOnline tax filing software for individuals and small businesses.
Form-specific diagnostics that validate answers during preparation and reduce preventable e-filing rejections.

How to Choose the Right Tax Return Software
We separate tax return software by how well it handles the work end to end: especially the correctness workflow around state and federal details, and how reliably data carries through when you switch between versions. The biggest differences show up in filing support and error handling as you work a real scenario.
Return profile coverage
Why it matters
Return profile coverage determines whether the software can represent your income, deductions, and credits without workarounds. When coverage is thin, you usually end up entering extra fields manually and increasing mistakes.
How to check
In a demo, choose a scenario like you actually have (jobs plus interest, self-employment, or education credits) and follow the input prompts. Confirm it collects every part you expect and produces a complete return summary for review.
Import and data reuse
Why it matters
Import and data reuse matters when you start with last year’s data or packaged statements and need fewer re-entries. Better reuse also reduces missing-field errors that trigger rejection.
How to check
Ask the vendor to show how it brings in data from a prior year or a typical statement export. Then run a “check for missing items” step and verify you can trace each imported number to the right place in the return.
State return support
Why it matters
State return support is often where best-of articles hide gaps. Even if the federal side is correct, weak state handling can change forms, calculations, and eligibility.
How to check
Request a live walkthrough for one state you need. Verify you can review state forms and see how the software maps your inputs to state-specific fields, not just a generic calculation screen.
Pre-filing review checks
Why it matters
Pre-filing review checks catch missing values and internal inconsistencies before you submit. A strong workflow prevents late surprises and reduces rework.
How to check
After entering the scenario, trigger the review/verification screen and expand the list of findings. Confirm each warning links to an input you can edit, and that the software distinguishes “informational” from “must-fix” items.
Change history for entries
Why it matters
Change history helps you recover when you correct mistakes and want to understand what changed. Without it, you may not trust the final numbers or be able to explain edits later.
How to check
Make a small edit (for example, adjust an income amount) and confirm the software records what changed. Then locate the same number in the review view to see the updated value and note of the change.
Tax forms update frequency
Why it matters
Tax forms update frequency affects whether the software stays aligned with current-year forms and instructions. When updates lag, you waste time re-entering data or hit wrong-form warnings.
How to check
In the settings or documentation area, ask what the product updates include for the current year. Compare the form list and labels shown in the demo to a current-year sample return your group brings in.
Red flags
- The software forces you into generic fields for your specific return profile.
- Review checks show warnings you cannot trace to an editable input.
- State forms are missing or only partially generated for your selected state.
Fit by situation
- If you have multiple income types or credits, prioritize return profile coverage.
- If you hate re-keying prior-year numbers, prioritize import and data reuse.
- If you file in a nonstandard state, prioritize state return support.
