How to proceed
- 1Create or edit a tax profile on the web or mobile for the tax year, country and canton or region, and personal basics. Review the profile deliberately in the confirmation step before saving.
- 2Work through Personal, Income, Deductions, Assets, and Completion as working values. Check each amount against original evidence; an amount shown is not an official assessment or calculation.
- 3Add tax files from Documents and review any transfer to income or deductions. Mark a section reviewed or complete only when your records and information support it.
- 4Use a linked official portal only as the next step and enter data there yourself. If no portal is listed, follow the responsible authority’s instructions or obtain professional advice.
Important
NEXO does not file a tax return, validate legal entitlements, or provide binding tax advice. Do not enter authority-portal credentials in NEXO, Support, or the assistant.
