Comparison Table
Asset-Map
SMBVisual planning software that maps assets, ownership, beneficiaries, and estate risks.
Asset-first mapping with linked scenario assumptions that regenerate worksheets and summaries when inputs change.
Asset-Map centers on an asset-first model that maps holdings into planning drivers like transfers, deductions, and valuation discounts. The calculation engine ties those inputs to federal estate tax computations and output artifacts used during the estate tax return workflow. Scenario comparison supports side-by-side reviews for trustees, attorneys, and wealth managers who need to evaluate multiple strategies quickly. The system also supports portability election tracking and links related assumptions to the final tax outputs.
A key tradeoff is that the setup process depends on consistent asset titling and scenario definitions, which requires governance during team use. Asset-Map fits best when an estate planning group runs recurring client workflows with similar asset structures and needs dependable updates across iterative drafts. It also fits teams that expect document capture alongside calculation changes for later review.
- +Asset inventory drives calculations and reduces spreadsheet drift across drafts
- +Scenario comparison keeps assumptions linked to output worksheets
- +Calculation history supports later attorney and fiduciary review
- +Portability election tracking ties carryover values to outputs
- –Scenario definitions require upfront consistency to avoid downstream errors
- –Some valuation workflows depend on manual data entry for inputs

Best for: Fits when estate teams need asset-mapped scenario modeling with audit-friendly change tracking.
TaxAct Professional
SMBProfessional tax preparation platform with estate and trust return modules.
Portability election tracking is embedded in the estate return input flow to keep spousal credit decisions connected to worksheets.
Estate attorneys and wealth managers use TaxAct Professional when they need a repeatable process for intake, calculation, and Form 706 assembly across multiple estates. The input structure keeps key estate data connected to worksheets and exported outputs, which reduces manual transcription between computation and draft forms. Portability election tracking is handled in the estate context so teams can document deceased spousal unused exclusion decisions without separate tracking sheets.
A tradeoff appears in automation depth for complex planning flows like trust funding analysis and valuation discount modeling, which still requires careful manual data entry and review. TaxAct Professional fits best when the workflow centers on Form 706 preparation and review cycles, not when the firm expects a deeply configurable planning engine with custom scenario branching.
- +Guided Form 706 preparation workflow reduces rekeying between tabs
- +Portability election tracking fields support consistent spouse credit documentation
- +Estate and gift intake linkage supports unified summary outputs
- +Exported worksheets support attorney review cycles

eMoney Advisor
enterpriseFinancial planning software with estate planning, cash flow, and tax analysis capabilities.
Portability election tracking tied to DSUE logic keeps federal estate computations consistent across multiple what-if iterations.
eMoney Advisor is designed for estate tax planning cases where ongoing scenario comparison needs to reflect a shared client fact set. Federal estate tax outputs and state estate tax variants can be generated from the same inputs, which helps teams run consistent what-if reviews for marital deduction choices, valuation discount modeling assumptions, and illiquid asset planning inputs. The workflow also supports document-style deliverables and audit-friendly planning trails that track changes across drafts. Collaboration controls are practical for mixed attorney and wealth manager teams, especially when multiple stakeholders contribute to the same planning model.
A tradeoff appears when jurisdiction coverage or special elections require careful input discipline, because missing or miskeyed facts cascade into downstream outputs and form-like sections. eMoney Advisor fits best when the planning team standardizes how assets, liabilities, beneficiary structures, and prior gifts are entered before running multiple Form 706 preparation and Form 709 preparation cycles. It is less efficient for one-off, minimal input engagements where a short worksheet is preferred over a repeatable client model.
- +Scenario comparison reuses a shared client fact set for consistent planning
- +Portability election tracking supports DSUE inputs across planning iterations
- +Collaboration workflow supports attorney and wealth manager review cycles
- +Deliverable outputs keep worksheet assumptions tied to client inputs
- –Jurisdiction and election inputs require strict data intake discipline
- –Deep edge-case modeling can take extra time to configure correctly
- –Worksheet-to-form mapping can feel rigid for highly customized practice workflows
- –Large client datasets can slow iteration during rapid scenario churn

This guide covers Asset-Map, TaxAct Professional, eMoney Advisor, Drake Tax, WealthCounsel, Total EstatePlan, Estate Planning Tools, CCH Axcess, Interactive Legal, and Thomson Reuters ONESOURCE.
The tools in these individual reviews were selected for how they connect estate inputs to return-ready artifacts, how they handle DSUE and spousal credit decisions, and how they manage audit-friendly scenario iteration. The comparisons also emphasize integration depth and automation surfaces so teams can align intake, worksheet regeneration, and document production without spreadsheet drift.
Estate Tax Planning Software for Form 706 workflows, scenario modeling, and portability tracking
Estate tax planning software is a calculation engine plus a workflow layer that turns estate and gifting inputs into Form 706 preparation steps and related outputs. Many platforms also track portability election details and carry DSUE logic through repeated scenario runs so federal estate computations stay consistent.
Asset-Map uses asset-first mapping to regenerate worksheets and summaries when linked scenario assumptions change, which targets drift across drafts. TaxAct Professional embeds portability election tracking into the estate return input flow to keep spousal credit decisions connected to the worksheets used during guided Form 706 preparation.
Estate Tax Planning Software capabilities that decide workflow reliability
Estate tax planning software must keep estate and gifting inputs synchronized with Form 706 preparation tasks, because drifting assumptions create inconsistent outputs across drafts. Tools in this category stand out when they regenerate worksheet results from linked scenario inputs, connect DSUE facts to portability election fields, and preserve planning-to-return traceability inside a matter or document workflow.
Linked scenario inputs that regenerate outputs
Asset-Map regenerates worksheets and summaries when linked scenario assumptions change so audit trails stay coherent across drafts. Interactive Legal chains Form 706 workflow steps so alternate assumptions remain synchronized during scenario comparisons.
Portability election tracking tied to DSUE logic
TaxAct Professional embeds portability election tracking into the estate return input flow so spousal credit decisions remain connected to guided worksheets. eMoney Advisor ties portability election tracking to DSUE logic so federal estate computations stay consistent across repeated what-if iterations.
Form 706 workflow guidance versus form-driven assembly
Drake Tax provides matter-scoped scenario planning that carries planning inputs into a Form 706-centric return workflow so outputs align with the return sequence. Estate Planning Tools uses a form-driven estate tax return workflow that maps scenario inputs into Form 706 preparation steps for consistent output assembly.
Matter-scoped documentation and return artifact organization
CCH Axcess organizes estate tax workflow artifacts as workpapers tied to the matter so planning outputs attach to return-ready document sets. Thomson Reuters ONESOURCE ties document management workflows to Form 706 and Form 709 preparation steps so governed scenario comparison can be attached to filing artifacts.
Valuation discount modeling coverage for illiquid assets
Total EstatePlan includes valuation discount modeling inputs designed for illiquid asset planning so scenario outputs can incorporate discount assumptions. Asset-Map supports valuation workflows but also relies on disciplined scenario definitions to prevent downstream errors when inputs vary.
Pick the estate tax engine plus workflow layer that matches the team’s planning-to-filing motion
A selection decision should start with how the team turns client facts into Form 706 preparation steps, because workflow-first tools behave differently from asset-first modeling tools. The second decision pivot should be how DSUE and portability election fields are maintained during scenario iteration, because tools differ in whether portability decisions live inside the return workflow or outside it in planning worksheets.
Choose the scenario control approach: asset-first mapping or form-first chaining
If the practice wants asset inventory to drive outputs, Asset-Map links asset-mapped scenario assumptions to worksheets so changes regenerate summaries automatically. If the practice wants the return flow to control sequencing, Interactive Legal chains Form 706 preparation steps so scenario inputs stay synchronized to workflow tasks.
Decide where portability election facts should live: embedded in return inputs or DSUE-logic-linked across iterations
If portability election fields must appear inside the estate return input flow for consistent spouse credit documentation, TaxAct Professional embeds portability tracking into the guided Form 706 workflow. If portability election decisions must remain consistent across many what-if runs from a shared fact set, eMoney Advisor ties portability tracking to DSUE logic during scenario comparisons.
Match jurisdiction complexity to the setup burden the team can absorb
If deep state estate tax variations are common, Drake Tax can require more manual setup for complex jurisdictions because its automation focus stays centered on a Form 706-centric workflow. If scenarios are more recurring with consistent firm conventions, WealthCounsel’s estate tax return workflow can reduce repeated reconfiguration by connecting calculations to Form 706 preparation tasks.
Separate valuation depth needs from workflow preferences
If valuation discount modeling for illiquid assets must be handled with structured inputs, Total EstatePlan and Asset-Map provide scenario outputs that depend on valuation inputs carried into calculations. If valuation discount modeling is secondary to maintaining repeatable Form 706 steps, Estate Planning Tools emphasizes form-driven calculation and output assembly rather than exposing deep calculation internals.
Assess collaboration and governance needs by workflow artifact scope
If multi-person drafting needs attachment of planning artifacts to a controlled matter package, CCH Axcess workpapers provide matter-based organization for repeatable planning-to-production cycles. If governance and collaboration require a governed scenario comparison attached to both Form 706 and Form 709 artifacts, Thomson Reuters ONESOURCE offers document workflows linked to those forms.
Who Estate Tax Planning Software serves best based on workflow and scenario demands
Estate tax planning software fits teams that must iterate scenarios while preserving linkage between client facts and Form 706 preparation steps. The right platform depends on whether scenario iteration is driven by asset mapping, DSUE-linked portability logic, or document-attachment workflows tied to matter production cycles.
Estate attorneys running repeated Form 706 planning and filing workflows
Drake Tax and WealthCounsel align planning outputs to the Form 706 workflow sequence and connect calculations to return preparation tasks so documents remain aligned to the filing process.
Wealth managers coordinating scenario modeling with DSUE and spousal credit decisions
TaxAct Professional and eMoney Advisor keep portability election tracking connected to the workflow or DSUE logic so repeated what-if iterations do not break spouse credit documentation.
Practices with a strong asset inventory process and scenario assumption governance
Asset-Map uses asset-first mapping to regenerate worksheets and summaries when linked assumptions change, which reduces spreadsheet drift across scenario drafts.
Multi-person teams that need matter-scoped workpapers and attachment to return-ready sets
CCH Axcess keeps estate tax workflow artifacts organized within the matter so scenario comparison and output sets can be reused across engagements.
Common implementation and workflow mistakes in Estate Tax Planning Software
Estate tax planning errors often come from scenario definition inconsistency, valuation input discipline gaps, and weak linkage between portability election facts and the worksheet or return workflow where they are used. Many teams also fail by choosing workflow automation without ensuring governance for how matter templates or workspace conventions are applied across engagements.
Changing scenario assumptions without ensuring worksheet regeneration stays linked
Asset-Map reduces drift by regenerating worksheets when linked scenario assumptions change, so teams should adopt its assumption linking workflow instead of exporting values into isolated spreadsheets. If scenario updates happen outside the linked model, outputs can diverge during drafts.
Treating portability election fields as standalone inputs instead of return-linked DSUE decisions
TaxAct Professional embeds portability election tracking into the estate return input flow, so teams should capture spouse credit facts in that guided flow and avoid duplicating the values elsewhere. eMoney Advisor expects strict data intake discipline for jurisdiction and election inputs, so teams should standardize those fields across scenario runs.
Underestimating setup work for complex jurisdictions and valuation workflows
Drake Tax can require more manual setup for deep state estate tax variations, so teams should test complex jurisdiction cases before rolling out firm-wide templates. Total EstatePlan and WealthCounsel both depend on correct valuation inputs for discount modeling, so valuation fields should be validated as part of the intake checklist.
Choosing a document workflow tool without confirming automation depth for complex planning patterns
CCH Axcess and Thomson Reuters ONESOURCE focus on matter-scoped workpapers or document workflows, so teams should validate complex planning patterns and automation needs before relying on form-linked artifacts alone. Estate Planning Tools centers on form generation and output assembly, so teams should confirm that generated results provide the calculation transparency their review process requires.
