Sovereign

Methodology

Transparency in algorithmic financial modeling.

Tax Engine

The Sovereign Tax Engine™ uses a deterministic waterfall model to calculate net income. We do not simply apply a flat tax rate. Instead, we:

  • Subtract standard deductions based on single-filer status.
  • Apply progressive tax bands specific to the jurisdiction (Federal/National).
  • Calculate mandatory social contributions (Social Security, NI, Health).

Note: We do not currently factor in complex credits, child allowances, or localized municipal taxes unless stated.

Salary Data

Base salary figures are aggregated from public employment datasets, labor market surveys, and normalized for the 2025 fiscal year.

We apply specific multipliers for:

  • Seniority: Junior (0.8x), Senior (1.35x), Lead (1.6x).
  • Location Tier: Major financial hubs receive a premium adjustment to reflect competitive labor markets.
