Establish the permitted stay
Ordinary Schengen short stays normally use a rolling 90 days in 180 days. A visa sticker can authorise less, so check the period printed on it. Residence or long-stay documents are not subject to the 90/180-day rule and need their own scope checked. Check the actual permission and your full date history before concluding that departure was compliant. Since 10 April 2026 the Entry/Exit System, used at the external borders of 29 European countries, has replaced passport stamping for non-EU short-stay travellers and allows automatic detection of overstayers. The Return Directive states that Ireland is not bound by it, and this guide does not cover European countries outside these EU rules.

What an overstay can lead to under the Return Directive
The Directive calls it illegal stay when a third-country national does not fulfil, or no longer fulfils, the conditions of entry in Article 5 of the Schengen Borders Code or other conditions for entry, stay or residence. Staying beyond your permitted period can fall under that definition. Member States must issue a return decision to any third-country national staying illegally, subject to listed exceptions. The decision must provide a period for voluntary departure of between seven and thirty days. That period can be extended, taking account of circumstances such as the length of stay, children attending school and other family and social links. A Member State may grant no period, or one shorter than seven days, if there is a risk of absconding, if a legal-stay application was dismissed as manifestly unfounded or fraudulent, or if the person poses a risk to public policy, public security or national security. If no period was granted, or you do not leave within it, Member States must take the measures needed to enforce the decision. Detention is allowed only to prepare the return or carry out removal, when less coercive measures cannot be applied effectively. Each Member State must set a limited detention period of no more than six months, which can be extended by a further twelve months only in the cases the Directive lists.
Entry bans
A return decision must be accompanied by an entry ban if no period for voluntary departure was granted or if the obligation to return was not complied with. In other cases a ban may be added. A ban prohibits entry into and stay on the territory of the Member States for a specified period. Its length depends on the individual case and in principle does not exceed five years, but it may exceed five years if the person is a serious threat to public policy, public security or national security. The Directive ties a ban to the return decision and the voluntary-departure period, not to a number of days overstayed.
Written decisions and your right to challenge them
Return decisions, entry-ban decisions and removal decisions must be issued in writing, with reasons in fact and in law and information about legal remedies. The person concerned must have an effective remedy to appeal against or seek review of them. Keep every notice and its date of receipt, together with your permission documents, travel dates and any evidence of illness, cancellation or other circumstances. The provisions read here do not give an appeal deadline, so ask the authority or a qualified adviser which national deadline applies to you.
Fines and criminal penalties are national
The Directive lets Member States leave out of its scope people who are subject to return as a criminal law sanction under national law. The new Return Regulation says it applies without prejudice to national criminal law, in particular provisions laying down effective, proportionate and dissuasive criminal penalties, including imprisonment, in relation to illegal stay. The EU texts read here do not set a fine for overstaying. Check the national rules of the country concerned and the decision you received.

The new Return Regulation
On 1 October 2026 the Council adopted a Return Regulation. The adopted text says it enters into force on the day after its publication in the Official Journal, repeals the Directive 12 months after entry into force, and that its remaining provisions apply 12 months after entry into force. Once it applies, an entry ban can last for a maximum of 10 years depending on the individual case, or up to 20 years for duly substantiated reasons, or for an indefinite duration where justified and proportionate to a security risk. The ban period starts from the date the person left the territory. Authorities may impose a ban, without a return decision, on someone whose illegal stay is detected at exit border checks, and may impose and notify it after the person has departed. A ban may be withdrawn, suspended or shortened where the person demonstrates that he or she returned voluntarily. Check the Official Journal for the publication date, because the dates in the adopted text are still blank.

Before further travel
Leaving does not necessarily end the matter: once the new Regulation applies, an entry ban can follow an illegal stay detected at exit, even after departure. Ask the authority or a qualified local adviser what a decision means for departure and future travel. This guide does not set a national fine, override a notice or establish an extension right.
Questions before acting
Does one extra day automatically cause a ban?
Not under the Directive's text. It requires an entry ban when no voluntary-departure period was granted or you did not leave within it, and allows one in other cases. A ban depends on the return decision, not on a count of days, and its length is decided case by case and in principle does not exceed five years.
Can this article tell me the fine?
No. The EU texts read here set no fine for overstaying and leave criminal penalties to national law. Use the national rules and the decision you received.
How long do I have to leave after a return decision?
The Directive says the decision must provide a period for voluntary departure of between seven and thirty days, with exceptions such as a risk of absconding, and the period can be extended for individual circumstances. Check your written decision for your actual period.
Can I be detained for overstaying?
The Directive allows detention only to prepare return or carry out removal, when less coercive measures cannot be applied effectively, in particular where there is a risk of absconding. Each Member State must set a limited period of no more than six months, which can be extended in listed cases.
Corrections in this revision
The previous version included statements without sufficient direct support. This revision removes or corrects:
- Automatic fines and one-to-five-year bans: removed
- Penalty tables based only on extra days: removed
- Universal detection and future-visa guarantees: removed
- Generic evidence and travel advice, and 'do not conceal dates' guidance: replaced by the rule that a ban can follow a stay detected at exit
- 'A ban is not an automatic penalty for each extra day': reworded to the Directive (tied to the return decision and departure period)
Review scope: legal and financial statements in this revised article. Recheck on a provider, professional, immigration or tax-rule change; reuse of dated figures requires a new check.
