CONTACT & CORRECTIONS
Help keep the numbers clear.
If you notice a suspected error, identify the country, income year, the relevant official provision and the step that appears incorrect. Use a made-up example if needed.
Please do not send your actual salary, payslip, tax identification number, bank details or other personal financial information.
What happens to a correction?
The operator should check the cited law, add a regression fixture and update the affected dataset’s version and review date. Other historical years should remain unchanged unless the same error affects them.
For advice on your own tax return or payroll deductions, contact your employer or a qualified tax professional.
