What is an A1 Form and how to apply?

Are you going to be working in another country? If so, you might need an A1 form. What is an A1 form and how do I get one?

Introduction

The A1 form is a certificate that you can use to prove that you pay social security in your home country. You must apply for an A1 form with the local tax office of your home country, which will send it to the tax office of the country where you're working. If you change jobs while abroad or if your employer changes, you must inform them by sending them a new A1 form. The number of months that you can work abroad without paying local taxes varies from one member state to another. Once an employer has received their A1 form from their employee's home country, they will keep it on file for up to 18 months.

The A1 form is a certificate that you can use to prove that you pay social security in your home country.

 The employer will then be able to deduct their share of contributions from your salary and send them back home.

If you're not eligible for this exemption or have already been taxed in Germany on earnings from other countries where you've worked before coming here (for example if your employer paid into these funds), we recommend speaking with our advisers first before applying for an A1 form.

The number of months that you can work abroad without paying local taxes varies from one member state to another.

Example: If you're a resident of Belgium and want to work in France for 3 months, then return home and then go back again after 6 months (i.e., 9 months in total), your personal allowance will be based on the time spent working in France as opposed to Belgium (in this case 2/3 of 4 = 2).

However, if this were not the case and instead was calculated based on how long you have been living outside your home country rather than how long each individual country has been visited during those 12 months (as is sometimes incorrectly assumed), then it would mean that someone who had lived overseas for just six weeks before returning home could claim their full personal allowance against all future earnings from abroad!

Once an employer has received their A1 form from their employee's home country, they will keep it on file for up to 18 months.

If the employee changes jobs during this time, they must get a new certificate from their previous employer and submit it to their new one. If an employer no longer needs the certificate after 18 months have passed, they must send it back to The National Insurance Office in Norway for destruction.

An A1 form is a useful tool for workers who are living and working in different countries, as it allows employers to avoid having to pay social security fees on behalf of foreign workers

An A1 certificate is valid for up to 12 months. This means that if you're employed by a company abroad, they may be able to apply for an A1 certificate on your behalf so that they don't have to pay national insurance contributions on your wages while you're overseas. If this application is successful then there will be no need for them to register under PAYE or deduct tax from any payments made during this period of time either - which could save them thousands of pounds each year!
