Working Abroad – Formalities, Documents, and Step-by-Step Preparation [Guide 2025]

A Complete Guide for Those Working Abroad: How to Avoid Costly Mistakes

Starting a job abroad is a huge opportunity, but it’s also a minefield. Formalities are key—working abroad requires good preparation to avoid costly errors and nullifying all your effort. We have prepared a complete guide that will walk you through the most important stages step-by-step and protect you from potential pitfalls.

1. A1 Certificate – The Key Formal Requirement for Working Abroad

The A1 Certificate is the official document that states: “Hey, Belgium! This person pays contributions in Poland, so leave them alone.” It’s like diplomatic protection for your wallet. Without it, you are defenseless and exposed to double social security taxation.

How to get the A1 – a step-by-step guide:

1. Log in to PUE ZUS (if you don’t have an account, set one up—it takes 15 minutes).
2. Fill out the application directly on the PUE ZUS platform. The system will guide you through the steps, depending on whether you are seconding an employee or leaving as a Sole Proprietorship (JDG).
3. Enter the data:
   • Period of secondment (max 24 months!)
   • Destination country
   • Details of the client/employer
4. Attach the documents:
   • Contract with the counterparty (sworn translation)
   • Work schedule
   • Confirmation of contributions paid for the last 3 months
5. Send and wait – usually 7–14 days.
6. Receive the PDF and print it in 3 copies.

Golden Tip: Submit your application a minimum of 30 days before departure. If ZUS rejects the application (approx. 20% of cases), you will have time for corrections.

2. Trusted Profile (Profil Zaufany) + PEL – Your Digital Key to Polish Offices

The Nightmare Scenario: John Without a Trusted Profile
It’s Friday at 4:00 PM in Belgium. A phone call from Poland: “ZUS needs clarification. Deadline: Monday.” Flight cost PLN 800, hotel PLN 300, lost day of work PLN 800. Total: ~PLN 2,000 for a single submission.

With a Trusted Profile? 5 minutes at the computer, and the issue is resolved.

Why is this so important?

The Trusted Profile (Profil Zaufany) is the key to e-government offices. PEL (Power of Attorney) allows your accounting firm to act on your behalf.

How to set up a Trusted Profile – the fastest way:

• Via electronic banking (90% of banks):
  1. Log in to your online bank.
  2. Find the “Trusted Profile” option.
  3. Confirm your details.
  4. Done!
• Alternative – in an office:
  1. Visit an official confirmation point.
  2. Bring your ID card.
  3. Fill out the application.
  4. Receive confirmation.

PEL for the accounting firm – step-by-step:

1. Log in to PUE ZUS.
2. Go to “My powers of attorney” (“Moje pełnomocnictwa”).
3. Select “Add power of attorney” (“Dodaj pełnomocnictwo”).
4. Enter the accounting firm’s NIP (Tax ID).
5. Select the full scope of authorization.
6. Confirm with your Trusted Profile.

⚠️ Important: Without PEL, your firm cannot file A1 applications or declarations for you.

Family Powers of Attorney – The Security Everyone Forgets

True Story: When Lack of Power of Attorney Cost a Fortune

Mark left for work in the Netherlands. After three months, his wife calls: a pipe burst, and the insurer requires a signature. Without a power of attorney, he had to fly back—a cost of over PLN 6,000. A single power of attorney costing PLN 60–100 would have solved the problem.

What powers of attorney should you prepare?

• General power of attorney for your spouse – bank, office, correspondence collection.
• Special power of attorney for parents – children’s matters, home emergencies.
• Power of attorney for the accounting firm – ZUS, Tax Office, company matters.

Practical tips:

• Form: Notarized for property matters, simple written form for current affairs.
• Content: Parties’ data, scope, effective date, signature.
• Storage: Keep the original with the proxy, a copy at home, and a scan in the cloud.

Smart Trick: Prepare a “crisis package”—a folder with powers of attorney and instructions, visible at home.

5. Cooperation with an Accounting Firm – An Investment, Not an Expense

The accountant reminded John about the A1 renewal—service cost of PLN 840/month vs. a potential penalty of PLN 50,000 for working “under the table.”

How to Choose the Right Firm – 5 Key Questions

1. How many A1 Certificates did you handle last year?
2. What do you do when ZUS rejects the application?
3. Do you operate online and use WhatsApp?
4. Can I grant you PEL?
5. Do you have experience with my destination country?

The TOP 5 Mistakes That Can Cost You Dearly

3. “25% of revenue from Poland? It’ll work out somehow” – ZUS verifies this.
4. Retroactive A1 is a myth – it is possible only in some cases.
5. “I’ll handle the formalities myself” – 70% of applications contain errors.iosków ma błędy.
