Tax calculator methodology
Transparent estimates for relocation planning — how we model income tax, social contributions, and take-home pay. Not a substitute for official software or professional advice.
What we calculate
- Progressive income tax using published marginal brackets
- Standard deduction / personal allowance where modelled
- Employee (and approximate self-employed) social contributions
- For US states and Canadian provinces: federal/national + regional layers
- Effective rate, monthly net, and a simple Tax Freedom Day date
What we do not include
- Every credit, deduction, AMT, local city tax, or property tax
- Treaty relief, FEIE elections, or multi-year residency tests
- Employer-side payroll taxes
- Investment / capital gains special regimes (unless a page explicitly says so)
Privacy
The interactive calculator runs in your browser. Gross income you enter is not required to be sent to MigrantIQ servers for a basic estimate.
Sources & refresh
Each jurisdiction page lists primary sources (IRS, HMRC, CRA, national tax authorities) with an access date. We target an annual tax-year refresh before the main filing season for major destinations.

Estimates for informational and educational purposes only — not tax advice. Rules vary by residency, deductions, credits, and filing status. Always verify with official authorities or a qualified tax professional.
