Every worker in Portugal must contribute to Social Security and pay taxes. On arrival in Portugal a number of official tasks must be carried out, which are:
- Sign up in Social Security. Whether the applicant is contracted full- or part-time for a company, or is self-employed they must pay Social Security contributions. You have to go to a Social Security office near your residence area.
- Get a Tax Identification Number which is obtained from the local Tax Office in the area of your residence.
You need to take the following documents:
- Passport or Identity Card.
- Authorized photocopies of tax returns for 3 years from the previous country of residence.
- National Insurance Number (or similar) from country of origin.
A temporary slip is issued and the tax number is sent to the registered home address within a few weeks.
