This is what a decision looks like when it becomes legible.
A Decision Record captures the modeled position, its drivers, its tradeoffs, and what would make it change—so the decision can be revisited, compared, and handed off.
Not advice. Not a black box. A position you can explain.
Most tax tools give you a number.
They don't tell you what's driving it. They don't record which thresholds mattered. They don't flag what would change the outcome.
A Decision Record is different. It captures the full structure of a modeled tax position—so the reasoning is preserved, not just the result.
Below is an example of what that looks like.
Sample Decision Record
Decision Summary
Modeled effective tax rate: 31.2% on $650,000 projected income, with additional Medicare tax on earned income above the filing-status threshold and self-employment tax exposure on modeled net self-employment earnings.
Primary Drivers
- Modeled effective tax rate: 31.2% on $650,000 projected income
- Additional Medicare tax on earned income above the filing-status threshold
- Self-employment tax exposure on $75,000 of modeled net self-employment earnings
Tradeoffs Accepted
- Safe harbor requirements satisfied under prior-year liability test
- Remaining payments to meet projected total liability: $117,490
- Contribution strategies affect bracket positioning within modeled inputs
What Would Make This Stale
- Income changes beyond projection
- Additional equity or capital events
- Changes to withholding or estimated payments
Assumptions
- Filing status: Single
- Tax law: IRC as amended through 2025 (post–H.R.1)
- Projected income: $650,000
- State: California
What this page shows
The record above is a sample output from PRISM's modeling engine. It reflects a single modeled scenario—not a recommendation.
Position — the modeled tax liability under defined inputs
Drivers — what's producing the outcome
Assumptions — what the model depends on
Tradeoffs — what was accepted
Staleness triggers — what would make this stale
Each section exists so the decision can be revisited without rebuilding it from scratch.
Why a Decision Record matters
A preview shows a position. A Decision Record preserves it.
Without preservation, the position disappears the moment the session ends. There's no way to compare it to a future state, hand it to an advisor, or verify what changed.
- The position is preserved as a durable artifact
- It can be re-run when inputs change
- It can be compared against alternate paths
- It can be handed to an advisor with full context
- It captures the reasoning—not just the result
Without that, the position disappears the moment you close the tab.
Calculators produce numbers. Records capture decisions.
A calculator output doesn't tell you why the number is what it is. It doesn't record which thresholds mattered. It doesn't flag what would change the outcome.
A Decision Record does all of that—and stays coherent when you return to it in three months.
Because decisions age. Artifacts don't.
See the position first. Preserve it when it matters.
Every PRISM session begins with a free preview—the position is visible, modeled, and real.
When the position is worth preserving, a Decision Record turns it into something durable: a structured, versioned artifact that doesn't expire when the session ends.
This is where the decision becomes yours—and stays yours.
