Why are cross-border RSUs complex?

Tax treatment depends on where you are tax resident across the grant-to-vest period, how your employer reports the award, and whether more than one country has taxing rights.

If I move to Ireland, will my RSUs be taxed in Ireland?

It depends on when you performed the work, the vest date, and your residency status. Use this guide as a checklist and verify for your scenario.

What documents should I keep?

Keep grant and vest statements, payslips for vest months, relocation dates, employment contract dates, and broker confirmations.

Timeline drives the tax story

Where you lived and worked during the grant-to-vest period determines which country has taxing rights. Record your move dates first.

Payroll processing is key evidence

If vesting was processed through Irish payroll (PAYE/USC/PRSI applied), the tax treatment is clearer. Check your vest-month payslip.

Model your RSUs with the Equity tool

Use the Equity Management tool to estimate vesting value and withholding — then use the timeline as a cross-check.

1) Start with the timeline

Write down: grant date, vest date(s), move date(s), and where you worked during each segment of the grant-to-vest period. If vesting is split across multiple tranches, keep the timeline per tranche.

2) Check what payroll actually did

Compare your vest statement to the vest-month payslip. If there is a corresponding PAYE/USC/PRSI deduction, the equity was processed through Irish payroll. If not, you may need extra reporting steps.

3) Evidence checklist
