Use this checklist when emergency tax applies on your payslip. The goal is to get the correct payroll instruction applied (your RPN) so your PAYE credits and rate band are used. This is general guidance and depends on payroll timing and your circumstances.
Before you do anything else, confirm these basics with payroll:
A surprising number of “emergency tax” issues come from a small data mismatch that prevents payroll from matching the correct Revenue instruction.
If the employment is not registered (or is registered incorrectly), payroll may not receive an updated instruction in time. Registering the job can help trigger an updated RPN.
Open Revenue myAccount and check that the employment is active and linked to the correct employer. If you have multiple jobs, confirm the one being paid under emergency rules is the one you updated.
Payroll timing matters. Even if your Revenue record is correct, payroll typically needs to pull the updated instruction before a pay run cut-off to apply it on the next payslip.
Practical questions to ask payroll:
The calculator page includes a copy-and-paste email template you can send to payroll. Always replace the PPSN placeholder before sending.
Without a PPSN, payroll commonly applies emergency rules at a flat 40% with no credits. The fix is usually administrative rather than “tax planning”.
If payroll applies the updated instruction on time, you may see your credits and rate band on the next payslip. If you overpaid in earlier periods, you may see an adjustment later, but timing can depend on whether payroll is cumulative or Week 1 basis.
If emergency tax has stopped but you are waiting for an adjustment, the refund timing guide explains why the timing differs between payroll setups.
