ExpressTaxExempt

vertical specialist

Web-based filing software for federal nonprofit tax returns and exemption forms.

9.5/10
Overall
Features9.7/10
Ease of Use9.5/10
Value9.3/10
Standout feature

IRS MeF submission packaging integrated into the preparation workflow to carry a completed return set to electronic filing.

ExpressTaxExempt is positioned for end-to-end 990 preparation, where staff input organization details, map supporting information into the correct sections, and produce a filing-ready return set. The tool’s scheduling and section-level completion approach reduces the chance that related schedules are left incomplete when core fields are finalized. Electronic filing support centers on producing an IRS MeF submission package and managing the submission lifecycle to completion.

A practical tradeoff is that complex cross-year attribution and edge-case schedule logic still requires consistent upstream input quality, since errors tend to surface during review rather than being inferred automatically. ExpressTaxExempt fits best when the same team prepares multiple returns for similar entity types and wants a repeatable internal review flow before filing.

Pros
  • +Guided return setup keeps required sections and schedules coordinated
  • +IRS MeF submission packaging supports direct electronic filing workflows
  • +Attachment and review steps keep documentation tied to return sections
  • +Repeatable preparation flow works well across multiple organizations
Cons
  • Complex edge cases still depend on clean source inputs
  • Some advanced schedule scenarios require careful manual verification
  • Multi-entity workflows can feel heavier without strict internal process
  • Limited visibility into submission failures beyond the review context
Use scenarios
  • Nonprofit accounting teams

Overall
Features9.2/10
Ease of Use9.5/10
Value9.0/10
Standout feature

Return workpapers and section completion tracking that supports review-to-signoff status across multi-user preparations.

ProConnect Tax is designed around return completion for exempt organization filings with schedule navigation and structured entry screens that map directly to required parts of a 990 package. The application includes review-ready checkpoints that help track completed sections and reduce omissions before submission. For teams handling multiple entities, its account and preparer workflow supports dividing work across users while keeping the return context intact.

A key tradeoff is that setup decisions, such as entity profile setup and preparer workflows, have to be done before returns scale across many organizations. ProConnect Tax fits best when a nonprofit compliance team needs repeatable 990 package assembly with consistent review steps for each fiscal-year return.

Pros
  • +Schedule-driven guided entry reduces missing section risk during 990 assembly
  • +Multi-user review flow supports preparer handoff and governing-body review timing
  • +IRS MeF submission handoff with acknowledgment handling for e-file issues
  • +Entity profile reuse supports consistent inputs across fiscal-year returns

TaxAct Professional

SMB

Professional preparer software covering Form 990 for exempt organizations.

9.0/10
Overall
Features9.2/10
Ease of Use8.7/10
Value8.9/10
Standout feature

Worksheet-driven preparation flow that ties source figures to final line items across 990 schedules.

TaxAct Professional supports Form 990, 990-EZ, 990-PF, 990-T, and 990-N e-Postcard preparation in a single preparation workflow. Guided inputs and section-by-section review help reduce missing line items during completion of return bodies and schedules. The editor workflow is oriented around worksheet completion and final form output review before IRS submission handling.

A key tradeoff is that complex governance narratives often require more manual drafting in the return text fields rather than structured content components. TaxAct Professional fits organizations and preparers handling a recurring exempt filing calendar where standardized data capture matters most.

Pros
  • +Guided inputs reduce missed lines across form and schedules
  • +Consistent review flow supports repeatable preparation for recurring filers
  • +Built-in support for multiple exempt organization return types
  • +Worksheet-driven capture helps maintain entity-level totals
Cons

Drake Tax

SMB

Professional tax software package including Form 990 preparation and e-filing.

8.3/10
Overall
Features8.3/10
Ease of Use8.4/10
Value8.3/10
Standout feature

Built-in 990 schedule workflow ties worksheet inputs to form lines for fewer manual transcription steps.

Drake Tax prepares Form 990 and related exempt organization returns inside a tax workflow designed for nonprofit filing use cases. The software supports standard 990 packages with form assembly, worksheet-driven entries, and return-level validation tied to common schedules.

Drake Tax’s workflow structure focuses on collecting nonprofit financial inputs and producing a submission-ready output that maps to the IRS filing formats. For teams that manage many exempt entities, it also supports recurring-year preparation patterns that reduce repeated data entry across returns.

Pros
  • +Form assembly workflow keeps 990 schedules and worksheets in a single preparation path
  • +Return validation catches common data entry gaps during preparation rather than at submission
  • +Recurring preparation patterns reduce rework when filing multiple entities in the same cycle
  • +Nonprofit-specific input screens align with common chart-of-accounts mapping needs
Cons

  • Extensive configuration of pipelines and templates takes time before scaling across entities
  • Non-standard filing variants can strain rigid task templates without additional process design
  • Large attachment sets can slow review navigation when folders are not structured tightly

Best for: Fits when nonprofit compliance teams manage many organizations and need controlled review handoffs for 990 packages.

#7

Tax 990

vertical specialist

Online software for preparing and electronically filing nonprofit Form 990 returns.

7.8/10
Overall
Features7.8/10
Ease of Use8.0/10

vertical specialist

Online preparation and electronic submission software for nonprofit Form 990 filings.

7.5/10
Overall
Features7.4/10
Ease of Use7.3/10
Value7.8/10
Standout feature

End-to-end packaging of preparation results into IRS submission artifacts with acknowledgment handling for follow-up work.

File990 is a 990 preparation workflow built around forming IRS-ready XML return files and handling the submission handshake for exempt organization filings. It supports core 990 variants through guided schedules and form-level checks, then produces outputs intended for IRS MeF filing workflows and reconciliation.

The main differentiator is its end-to-end focus on generating the specific artifacts used for filing rather than only capturing values in a generic spreadsheet style interface. For teams that need repeatable preparation runs across fiscal-year returns, File990 centers on repeatable data entry and exportable filing packages.

Pros
  • +Produces IRS-ready XML return files targeted for IRS submission workflows
  • +Guided schedule flow reduces omissions on multi-part 990 workpapers
  • +Designed for repeatable preparation runs across fiscal-year returns
  • +Includes submission acknowledgment handling to support follow-up on rejections

#9

Form 990 Online

SMB

Web-based 990 and 990-EZ preparation and e-filing platform operated by the Civic Leadership Project nonprofit.

7.2/10
Overall
Features7.1/10
Ease of Use7.3/10
Value7.1/10
Standout feature

Acknowledgment-based e-file rejection resolution that targets specific return inputs instead of requiring full rework.

Form 990 Online supports e-filing workflows for Form 990 series returns through IRS submission packaging and return-level checks. It guides inputs across common schedules such as Schedule O and attachments that feed the final XML return file used for IRS MeF filing.

The workflow includes e-file rejection resolution paths based on IRS acknowledgments, which helps teams iterate without rebuilding the full return. Data entry is organized around completed sections and computed form fields, which reduces cross-form transcription when preparing Schedule A or Schedule B.

How to Choose the Right 990 tax preparation software

Form 990 tax preparation software is built to move exempt organization filing work from guided form and schedule entry through MeF-ready submission packaging with fewer omissions. This buyer’s guide covers ExpressTaxExempt, ProConnect Tax, TaxAct Professional, Thomson Reuters UltraTax CS, Drake Tax, TaxDome, Tax 990, File990, Form 990 Online, and K1x 990 Tracker.

The strongest differentiators show up in how each tool coordinates schedules to form lines, how it packages returns for IRS submission artifacts, and how it handles review checkpoints across multi-user workflows. ExpressTaxExempt leads with IRS MeF submission packaging integrated into the preparation workflow, while ProConnect Tax emphasizes section completion tracking that supports review and signoff across preparers.

990 tax preparation software for guided schedules, validation, and IRS submission workflows

990 tax preparation software is the workflow that assembles Form 990 workpapers into a complete return package with guided schedule mapping, in-product validation, and submission outputs. Tools such as ExpressTaxExempt focus on carrying a completed return set into IRS electronic filing through MeF submission packaging integrated with preparation.

Other products emphasize different execution points inside the same overall workflow. ProConnect Tax provides return workpapers and section completion tracking that support review-to-signoff status across multi-user preparations, and Thomson Reuters UltraTax CS keeps form and schedule linkage tied together through in-product diagnostics during data entry.

990 workflow coordination, validation depth, and filing packaging

For Form 990 preparation, the decisive feature is how a tool ties schedule inputs to the correct form lines during assembly so omissions do not survive into filing artifacts. This guide prioritizes coordination mechanisms like guided schedule mapping, in-product diagnostics, and section-driven completion tracking that reduce cross-check work.

Another deciding feature is how the tool packages preparation output into IRS submission-ready artifacts and how it handles acknowledgment outcomes during the MeF filing loop. ExpressTaxExempt is highlighted for integrated IRS MeF submission packaging, while File990 and Form 990 Online emphasize XML and acknowledgment handling in the submission workflow.

  • MeF-ready submission packaging integrated into preparation

    ExpressTaxExempt integrates IRS MeF submission packaging into the workflow so a completed return set can move directly into electronic filing. File990 also targets IRS submission artifacts with acknowledgment handling, but ExpressTaxExempt ties that step more tightly to the preparation path.

  • Schedule-to-form line linkage with guided mapping and validations

    Tax 990 uses schedule and attachment mapping with validation checks that ensure return sections line up before submission. Drake Tax uses a built-in 990 schedule workflow that ties worksheet inputs to form lines to reduce manual transcription.

  • Multi-user review checkpoints tied to sections and signoff timing

    ProConnect Tax includes return workpapers and section completion tracking that supports review-to-signoff status across multi-user preparations. K1x 990 Tracker adds readiness checks for moving between draft and review stages, with workflow state management focused on preparation milestones.

  • In-product diagnostics that control linkage during data entry

    Thomson Reuters UltraTax CS keeps form and schedule linkage tightly controlled through in-product diagnostics during the return workflow. ExpressTaxExempt reinforces linkage by coordinating required sections so guided setup keeps schedules coordinated during assembly.

Choose by filing path, workflow governance, and where errors surface

The first fork is where the process ends up after preparation. Some tools carry a completed return set into IRS submission through integrated MeF packaging, while others focus on XML return file output or on acknowledgment-based rejection resolution.

The second fork is where review governance lives. ProConnect Tax centers review checkpoints and section completion tracking across multi-user work, while TaxDome centers case timeline workflows with reviewer assignment and approval gates that manage handoffs during data collection and preparation.

  • Pick the submission endpoint the software is built to produce

    If the required workflow is to move directly from a completed return set into IRS electronic filing, ExpressTaxExempt’s integrated IRS MeF submission packaging is a primary match. If the requirement is producing IRS-ready XML artifacts as the end product, File990 focuses on XML return files targeted for IRS submission workflows.

  • Route review governance through section completion tracking or case timeline gates

    Choose ProConnect Tax when review-to-signoff status needs to be tied to section completion across multiple preparers. Choose TaxDome when document request, reviewer assignment, and approval gates must run inside one case timeline for many organizations.

  • Select based on how schedule linkage errors are prevented or caught

    Choose Tax 990 when schedule and attachment mapping validations must flag missing or misaligned return sections before IRS submission. Choose UltraTax CS when the goal is schedule-level validation checks enforced by consistent 990 data entry screens and in-product diagnostics.

  • Match narrative workload realities to the preparation flow

    Choose TaxAct Professional when worksheet-driven preparation can tie source figures to final line items across 990 schedules. Plan for manual narrative shaping needs since narrative text often requires extra handling in return fields.

  • Constrain manual rework by using worksheet-to-line workflows

    Choose Drake Tax when worksheet inputs must tie to form lines in a single preparation path to reduce manual transcription steps. Choose ExpressTaxExempt when guided return setup needs to coordinate required sections so fewer schedule gaps reach MeF packaging.

  • For rejection handling, prioritize acknowledgment mapping and targeted rework

    Choose Form 990 Online when acknowledgment-based e-file rejection resolution must map acknowledgments back to specific return inputs and fields. Choose ExpressTaxExempt when the priority is integrated MeF submission packaging that carries the completed return set into electronic filing without breaking the preparation workflow.

Who should buy this 990 tax preparation software

Different tools emphasize different control points in the 990 process. Teams that manage recurring filings often benefit from workflow repeatability and schedule-to-line linkage, while distributed teams benefit from review checkpoints or approval gates.

Some tools also fit specific submission-loop requirements, like XML return artifacts or acknowledgment-based rejection resolution. This guide maps those capabilities directly to operational needs seen in exempt organization filing workflows.

  • Compliance teams preparing recurring Form 990 variants

    ProConnect Tax supports section completion tracking and review-to-signoff status across multi-user preparations, which fits recurring 990 cycles. TaxAct Professional supports worksheet-driven consistency for guided inputs tied to final line items across schedules.

  • Tax staff that must move completed returns into IRS e-filing with minimal workflow breaks

    ExpressTaxExempt integrates IRS MeF submission packaging into the preparation workflow so the completed return set can flow directly to electronic filing. File990 packages preparation results into IRS submission artifacts aligned to XML filing workflows.

  • Nonprofit compliance operations that manage many organizations and reviewer handoffs

    TaxDome provides client portal workflows that enforce document requests, reviewer assignment, and approval gates in a single case timeline. K1x 990 Tracker adds workflow state management and readiness checks tied to 990 preparation milestones.

  • Tax departments that need standardized internal validation controls across multiple entities

    Thomson Reuters UltraTax CS maintains form and schedule linkage through in-product diagnostics and schedule-level validation checks. Drake Tax concentrates 990 schedules and worksheets into a single preparation path with in-app validation that catches common data entry gaps.

  • Teams focused on schedule mapping consistency before submission

    Tax 990 uses guided schedule mapping and form structure validation that flags missing sections before filing. File990 and Form 990 Online both emphasize preparation-to-filing artifact alignment, with Form 990 Online focusing on acknowledgment-based rejection resolution.

Common mistakes in 990 software selection and deployment

A common selection mistake is choosing a tool based on form completion screens without aligning the product to the submission endpoint the team actually runs. Tools vary in how they package MeF output and how they handle acknowledgment outcomes after e-file submission.

Another common deployment mistake is underestimating how much process discipline is required to keep large portfolios consistent. ProConnect Tax’s template setup discipline and UltraTax CS’s automation dependence on firm process design can create gaps if governance and review timing are not defined.

  • Selecting based on guided entry but ignoring how submission packaging is handled

    ExpressTaxExempt focuses on carrying a completed return set into IRS electronic filing via integrated IRS MeF submission packaging. File990 focuses on IRS-ready XML return files, and Form 990 Online emphasizes acknowledgment-based e-file rejection resolution, so mismatch with the team’s filing loop creates rework.

  • Assuming validation errors will be caught at the same stage across tools

    Tax 990 validates schedule and attachment mapping within the filing workflow to flag missing sections before submission. UltraTax CS relies on in-product diagnostics during data entry, so skipping disciplined review workflows can still allow omissions if diagnostics are not used consistently.

  • Running multi-preparer work without a defined review checkpoint workflow

    ProConnect Tax provides workpapers and section completion tracking for review-to-signoff status, which requires defined signoff checkpoints. Form 990 Online limits governance controls like RBAC and audit log for multi-preparer teams, so teams may need extra process controls outside the tool.

  • Using worksheet-driven preparation while expecting fully automated narrative generation

    TaxAct Professional ties source figures to final line items across schedules through worksheet-driven preparation, but narrative text often needs manual shaping in return fields. Teams that expect narrative automation can lose time during final data review and formatting.

  • Overbuilding custom integrations when the software’s automation depth is limited

    Drake Tax reports limited automation depth for custom data pipelines that require deep API access. K1x 990 Tracker has no documented API surface for automation or integrations, so integration-first plans can stall on workflow design.

Frequently Asked Questions About 990 tax preparation software

How do ExpressTaxExempt and File990 differ in their XML return file workflow?
File990 centers on generating IRS-ready XML return file artifacts and packaging them for the IRS MeF submission handshake. ExpressTaxExempt integrates IRS MeF submission packaging into the preparation workflow while keeping the guided data entry, review steps, and document attachment flow inside one process. Teams that need reconciliation and follow-up after submission artifacts typically evaluate File990 first, while controlled guided MeF packaging during preparation points to ExpressTaxExempt.
Which tools provide schedule-level review checkpoints for multi-user signoff?
ProConnect Tax provides governance with role-based access and explicit review checkpoints across guided inputs. ExpressTaxExempt supports review steps that keep schedules aligned during intake-to-filing execution. ProConnect Tax is the tighter fit for teams that need return workpapers and section completion tracking for review-to-signoff status across multiple preparers.
What breaks if a team needs acknowledgement-based e-file rejection resolution?
Form 990 Online includes an acknowledgement-based e-file rejection resolution workflow that targets specific return inputs instead of requiring full rework. Tools without that targeted loop still allow correction, but the operational cycle becomes slower because preparers must rebuild or revalidate more of the return to find the failing input. For iterative MeF failures tied to specific sections, Form 990 Online reduces rework scope.
When is TaxDome a better fit than a form-only 990 preparation workflow?
TaxDome is designed around intake-to-review case pipelines with reviewer handoffs, gated approvals, and secure document requests. A form-only workflow may handle data entry and validations, but it does not enforce submission readiness as a case timeline with routing rules. TaxDome fits teams that manage many exempt organizations and need controlled document and approval movement tied to the 990 cycle.
How do TaxAct Professional and Drake Tax ensure worksheet-driven consistency across 990 schedules?
TaxAct Professional uses a worksheet-driven preparation flow that ties source figures to final line items across 990 schedules. Drake Tax maps worksheet inputs to form lines inside its 990 schedule workflow to reduce manual transcription steps. Teams with frequent figure reuse across multiple entities typically benefit from Drake Tax’s tighter worksheet-to-line linkage, while TaxAct Professional suits environments that rely on guided worksheet review.
Which tool is most directly aligned to standardized multi-entity preparation controls?
Thomson Reuters UltraTax CS is built around structured input screens plus in-product diagnostics that catch missing or conflicting amounts before filing. UltraTax CS also supports organizer and return collaboration patterns common in firm tax departments. ExpressTaxExempt offers MeF packaging integrated into preparation, but UltraTax CS is the stronger option for departments standardizing nonprofit chart of accounts and review controls across multiple entities.
How does K1x 990 Tracker help when the real requirement is preparation workflow state management?
K1x 990 Tracker focuses on status tracking, revision control cues, and return completeness checks for recurring Form 990 cycles. It treats preparation as a workflow layer tied to return readiness milestones instead of only capturing values. Teams that already have data entry coverage but need governance of draft, review, and revision steps generally benefit more from K1x 990 Tracker than from form-centric tools.
What tradeoff appears when Tax 990 emphasizes schedule and attachment mapping during filing?
Tax 990 emphasizes schedule and attachment mapping with validations that ensure return sections line up before IRS submission. That depth reduces manual alignment errors, but teams that also need extensive review checkpoint governance across multiple preparers may find ProConnect Tax’s multi-user workpaper tracking more suitable. Tax 990 is most effective when schedule alignment and attachment mapping are the primary failure points.
How do teams typically start a 990 cycle inside ExpressTaxExempt compared with Tax 990?
ExpressTaxExempt starts with guided data entry that carries the completed return set into IRS MeF submission packaging within the same workflow. Tax 990 starts with a guided preparation workflow that includes validations and reusable setup tied to each filing year plus document mapping for schedules and attachments. Teams that want MeF packaging integrated from early preparation typically start with ExpressTaxExempt, while teams that prioritize repeatable year-specific queues and mapping validations start with Tax 990.
