Research in progress

What we evaluate

  • Day and location tracking

    Records where assignees and travelers work each day for tax tests.

  • Tax equalization

    Calculates hypothetical tax and year-end equalization settlements.

  • Shadow payroll support

    Supplies or runs host-country shadow payroll for assignees.

  • Gross-up calculation

    Grosses up relocation and assignment benefits for tax.

  • Assignee compensation collection

    Collects pay, allowances, expenses and equity income by country.

  • Assignment cost projections

    Estimates total tax and benefit cost before an assignment starts.

  • Social security coverage tracking

    Tracks certificates of coverage and their expiry.

  • Withholding exemption tracking

  • Advisor collaboration

    Shares assignee data and documents securely with tax advisors.

  • Secure document vault

What matters for enterprises

  1. Multiple policies and assignment types

    Long-term, short-term, commuter and permanent moves follow different rules.

  2. Business traveler tracking

    Frequent travelers can create host-country tax exposure too.

  3. Payroll, expense and equity integration

    Compensation for assignees comes from many systems.

  4. Audit trail and secure documents

    Assignee files hold sensitive tax and family data.

How to choose expat tax & relocation software

6 criteria · Requirements by company size · 5 red flags

Choose on how well the tool connects four things: where people are, what they are paid, what the tax policy promises them, and what the advisors and payroll teams need to file. Gaps between those steps are where cost and penalties appear.

Bring a real assignment to the demo and ask the vendor to show the day count, tax cost estimate, equalization calculation and shadow payroll output for it.

  1. Day counting and location tracking

    Residence, exclusions and host-country liability often depend on days in each country, such as the IRS physical presence test of 330 full days in 12 consecutive months.

  2. Tax equalization and hypothetical tax

    Equalization policies promise assignees they pay no more or less than at home, which needs a hypothetical tax calculation and a year-end settlement.

  3. Shadow payroll support

    When an assignee stays on home payroll but owes host-country tax, a shadow payroll reports and withholds there.

  4. Gross-up calculations

    Relocation and assignment benefits are generally taxable, so gross-ups decide who bears the tax.

  5. Assignee compensation and benefits data

    Allowances, housing, home leave, bonuses and equity all affect tax in more than one country.

  6. Social security coverage tracking

    Totalization agreements avoid double social security taxation, and an exemption requires a certificate of coverage.

Requirements by company size

  • Enterprises

    • Many policies, countries and assignment types
    • Integration with payroll, expenses, equity and travel systems
    • Audit trail and secure document handling

    Watch out for

    • Equity income across countries handled outside the tool
    • Business traveler tracking left out of scope
    • Long integration projects across payroll providers

Red flags

  • Day counts rely only on annual employee self-reporting
  • Equalization settlements are calculated outside the system
  • No record of which benefits were grossed up and why
  • The tool works only with one advisor firm
  • No tracking of certificates of coverage
