Colorado deduction limit above $300,000
Affected: Paycheck calculators, take-home pay map, and state tax comparison
The single-filer model now limits the federal standard deduction retained for Colorado to $1,000 when modeled federal adjusted gross income exceeds $300,000. Previously it retained the full $16,100, understating modeled state income tax by $664.40 at those income levels. The 4.4% base rate remains provisional pending any later TABOR adjustment.

Utah taxpayer credit in the single-filer model
Affected: Paycheck calculators, take-home pay map, and state tax comparison
Added the basic taxpayer credit shown in the draft 2026 TC-40: 6% of the modeled $16,100 federal standard deduction, reduced by 1.3% of income above $18,696 and limited to tax owed. Previously this credit was omitted, overstating modeled tax for eligible incomes. At $50,000 with no pre-tax adjustments, estimated annual state tax falls from $2,225 to $1,665.95. Utah remains provisional because the source return is a draft; dependent credits and other adjustments are outside this model.

2025 and 2026 federal tax descriptions

Updated the 2025 standard deduction to $15,750 single / $31,500 married filing jointly / $23,625 head of household and corrected copy that described 2026 bracket thresholds as frozen. The 2026 thresholds are inflation-adjusted.

Scenario URL and analytics privacy
Affected: Interactive calculators, preset links, and cross-calculator handoffs
Current calculator changes now stay in memory until a visitor explicitly copies or follows a scenario link. Those links use a browser fragment rather than a query string. Legacy query variants remain readable but receive a noindex response, and analytics page locations and events omit query strings, fragments, input values, and calculated results.
