eMoney Advisor is the best pick for estate planning teams running repeated what-ifs with shared client data because portability election tracking tied to DSUE logic keeps federal estate computations consistent across iterations, while Asset-Map fits small estate teams that want audit-friendly asset-mapped scenarios thanks to its asset-first mapping that regenerates linked worksheet outputs when inputs change.

Comparison Table
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

Best for: Fits when estate planning teams run repeated scenarios with shared client data and need collaboration-ready planning outputs.
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

How to Choose the Right Estate Tax Planning Software
In estate tax planning software, the differences that show up during demos are usually about how Estate tax calculation accuracy is handled, how automation supports your workflow, and how well the tool keeps your scenario assumptions consistent. We focus on those checks so you can compare tools without relying on promises.
Calculation coverage breadth
Why it matters
Estate tax planning depends on correct handling of taxable estates, adjustments, and common planning inputs. A tool with narrow calculation coverage forces manual work and increases the chance of inconsistent numbers.
How to check
Ask for a walk-through using a case with both an estate value and planning actions (for example, gifts). Confirm which outputs it produces and what it cannot compute without manual spreadsheets.
Assumption tracking and lock dates
Why it matters
Estate plans often hinge on dates and election-like inputs, and small assumption changes can shift results. Assumption tracking and lock dates helps prevent silent mismatches across scenarios.
How to check
Create two scenarios that differ by one input date or amount, then review whether the system clearly shows what changed and when it was captured. Export a summary and check that assumptions are labeled and auditable.
Scenario comparison outputs
Why it matters
Scenario comparison helps you evaluate tradeoffs without rebuilding everything each time. Clear scenario outputs reduce the risk of cherry-picking results that don’t match the inputs.
How to check
Run at least two scenarios with different planning levers and check that the tool produces side-by-side outputs. Look for a scenario narrative or changelog that ties each output difference back to inputs.
Workflow automation for planning steps
Why it matters
Automation and API surface matter when plans evolve and you revisit assumptions. If workflow is manual, you spend time re-entering data instead of validating planning logic.
How to check
Ask the vendor to demonstrate an end-to-end planning cycle: entering inputs, generating results, and producing a review package. Time the steps and note which parts require spreadsheets or re-keying.
Data import and export formats
Why it matters
Estate tax planning often starts in documents and spreadsheets, then moves into your working model. Data import and export formats keep your process intact when clients, counsel, or internal teams need the same numbers.
How to check
Request a sample import template and test it with a simple dataset. Then export results in a format you can hand to someone else and verify the exported fields match what the tool used.
Collaboration-ready review artifacts
Why it matters
Planning outputs must be reviewable by non-authors without losing the meaning of assumptions. Collaboration-ready review artifacts reduce misunderstandings during attorney and client review.
How to check
Check whether the tool can generate a consistent review packet that includes inputs, key outputs, and scenario differences. Verify whether it provides a clear audit trail (timestamps or revision history) for changes.
Red flags
- Outputs change when you edit an input, but the tool doesn’t show what assumptions drove the change.
- Scenario comparison results don’t trace back to the specific inputs you edited.
- Imports or exports require re-keying or lose labels needed for review.
Fit by situation
- If you run many what-if runs for the same client, prioritize Scenario comparison outputs.
- If you revisit a plan weeks later with updated dates, prioritize Assumption tracking and lock dates.
- If your team must reuse the same numbers across documents, prioritize Data import and export formats.
