The Assignment

One engineer. Two tax systems.

Elena Müller relocates from Munich to São Paulo. Her employment contract guarantees take-home parity. Without equalization, she's simultaneously liable in Germany for hypothetical tax on her global income and in Brazil for her actual host-country income — paying into two systems with no framework to arbitrate.

The Obligation Stack

One move triggers four parallel obligations.

A single cross-border assignment activates hypothetical tax calculation against home-country norms, host-country liability reconciliation, social security totalization under applicable bilateral treaty, and shadow payroll construction for CFO sign-off. These don't run sequentially — they run simultaneously, each feeding the other.

Scale

Fifty assignees. One clean ledger.

When your mobility program spans twelve jurisdictions and two hundred assignments, the obligation stack multiplies exponentially. Each node in this constellation is a real filing, a real treaty position, a real variance that compounds if unmanaged. Equalize maps the constellation — then collapses it into auditable, jurisdiction-by-jurisdiction reconciliation your CFO can sign.
