Ireland citizenship & Stamp 4 date calculator
Enter your reckonable-residence date and, where relevant, a separate qualifying employment date or marriage date. See the resulting application planning milestones and check the final-year absence thresholds. This is not a citizenship grant date or an assessment of your complete residence history.
Stamp 4 employment milestone
15 October 2025
21 months after 15 January 2024
Application planning milestone — not a grant date
15 January 2029
5-year calendar milestone assuming uninterrupted reckonable residence. Absences and other eligibility conditions still apply.
Final-year absence check: not entered
- • Critical Skills Employment Permit holders may qualify to renew under Stamp 4 conditions after 21 months of qualifying employment in the State. Apply through the ISD renewal portal; the current process is not a Stamp 4 support-letter application. Naturalisation uses a separate reckonable-residence clock.
- • Stamp 4: 21 months from the separately entered qualifying employment date; evidence and renewal approval are still required.
- • The citizenship result is a residence-based application planning milestone, not a citizenship grant date. It assumes uninterrupted reckonable residence and does not audit permission periods or a rolling 9-year/5-year window.
- • Check the conditions of each permission: Stamp 1, qualifying Stamp 1G and Stamp 4 can count. Student Stamp 2/2A generally do not; limited young-adult exceptions need separate assessment. Current ISD citizenship guidance includes Stamp 0 under reckonable permissions, subject to its conditions.
- • The continuous final year normally allows 70 whole days away, with up to 30 additional days only if the Minister accepts exceptional circumstances. Part-days are excluded by section 15C. For a spouse application count absence from the island of Ireland, not simply from the Republic.
- • You must also be of good character and satisfy the Minister; the decision is discretionary. These are indicative planning dates only - confirm with the official ISD guide, Naturalisation Residency Calculator and Citizens Information before relying on a date.
- • Final-year absences have not been checked. Enter a whole-day total for a preliminary threshold check; you still need a complete travel record.

Ireland citizenship and Stamp 4 verdict context
Verified 2026-09-10
The calculator result should be read as route-clock arithmetic over ISD guidance: Critical Skills Stamp 4 after 21 months, General Employment Stamp 4 after 57 months, standard naturalisation after 5 years reckonable residence, Irish-citizen spouse/civil-partner naturalisation after 3 years, and current refugee/stateless naturalisation on a 5-year clock.
A generated date is not an ISD or Minister for Justice decision. Reckonable residence, continuous final-year residence, the 70/30 absence rule, proof scorecards, good character, joint spouse evidence and ministerial discretion still control the outcome.
Critical Skills Stamp 4 clock
21 months
ISD says Critical Skills Employment Permit holders can be eligible for a Stamp 4 permission after 21 months from commencement of employment in the State.
General Employment Stamp 4 clock
57 months
ISD says General Employment Permit and Intra-Company Transfer Employment cases can be eligible for Stamp 4 after 57 months from commencement of employment in the State.
Standard naturalisation residence clock
5 years in the last 9
ISD lists 5 years of legal/reckonable residence in the last 9 years, including 1 full year of continuous residence immediately before applying.
Final-year absence rule
70 days plus possible 30 exceptional days
ISD says the final 12 months normally allows no more than 70 days outside Ireland; an extra 30 days may be allowed for rare, severe or unavoidable events, but over 100 days is ineligible.
Irish-citizen spouse or civil partner clock
3 years
ISD lists 3 years reckonable residence on the island of Ireland, 3 years married or in civil partnership, and a continuous final year for spouse/civil-partner naturalisation cases.
Refugee/stateless current clock
5 years from grant of status
Current ISD guidance says refugees/stateless people need 5 years of reckonable residency from grant of status; applications received before 8 December 2025 continue under the previous 3-year rule.

Dates are produced by the calculator above from the published periods. They assume continuous, reckonable residence within the absence limits — they do not by themselves grant Stamp 4 or citizenship.
About this calculator
Stamp 4 is an immigration permission, not citizenship or the same thing as the separate Long Term Residency scheme. Critical Skills permit holders may qualify for the Stamp 4 upgrade after 21 months; General Employment permit holders after 57 months. Naturalisation usually needs 5 years of reckonable residence, with a 3-year route for the spouse or civil partner of an Irish citizen and a current 5-year clock for refugees/stateless people, including a continuous final year. This tool does the date arithmetic over those periods, checks separate employment and marriage milestones and flags absence thresholds; it does not establish which permissions are reckonable, validate travel records or assess good character.
Before relying on a planning date
Check your permission history backwards from the intended application date. The standard test uses a final continuous year plus four years in the preceding eight; the spouse route uses a final continuous year plus two in the preceding four. Prior qualifying periods can matter even after an interruption. This forward planner deliberately does not solve that rolling-window calculation.
Use the official ISD residency calculator for individual permission periods if you are within its scope. Its form is not for UK, EU, EEA or Swiss nationals; those applicants provide documentary residence evidence. ISD also says the calculator does not work for refugees. Stamp 1G can be entered as Stamp 1 in the official form.
Being old enough to apply, good character, residence evidence, living together for spouse cases, continued-residence intentions and the required declaration remain separate. Minors, descent/Foreign Births Registration, Irish-association waivers and public-service exceptions are outside this tool. Subsidiary protection is not interchangeable with a refugee declaration: follow the standard reckonable-residence guidance for your permission.
The date shown is an application-planning milestone, not the date you become Irish or receive a passport. Assessment, approval and the required citizenship declaration happen afterward; passport application is separate. Calendar anniversaries, including a 29 February date clamped to 28 February, must still be checked against the official day-count and continuous-year requirements.

A forward calendar planner for uninterrupted reckonable residence, not an official permission-period audit, final-year continuity decision or grant forecast. Interrupted residence, exceptional waivers, minors and complex permission histories need separate assessment. This independent calculator is for planning only; the authoritative result is the relevant government or caseworker decision.
FAQs
When can I apply for Irish citizenship by naturalisation?
The standard residence test is one continuous year immediately before application plus four years in the preceding eight. Spouse/civil-partner applications use one continuous year on the island of Ireland plus two years in the preceding four, and a separate three-year marriage/partnership condition. Current ISD guidance uses five years from status grant for refugees/stateless people; applications received before 8 December 2025 retain the previous three-year policy. Meeting a period does not guarantee citizenship.
How long until I can get Stamp 4?
The current ISD upgrade process uses 21 months of qualifying employment for Critical Skills permit holders and 57 months for General Employment Permit holders. Eligible applicants renew under Stamp 4 conditions through ISD. This is not citizenship or an automatic permanent-residence grant; your employment start and reckonable-residence start can differ.
What counts as reckonable residence?
ISD identifies Stamp 1, qualifying Stamp 1G and Stamp 4 residence as reckonable, subject to conditions. Its current citizenship guide also lists Stamp 0, subject to its conditions. Student Stamp 2/2A generally do not count, with limited young-adult exceptions requiring separate assessment. Check each permission and any gaps rather than assuming all time after arrival counts.
Does this calculator confirm I will get citizenship?
No. This is a forward calendar planner, not a permission-history audit or a prediction of approval. It does not calculate a rolling nine-year/five-year history, determine whether each permission counts, or decide good character, accepted exceptional absences or ministerial discretion. The official ISD calculator accepts individual permission periods for applicants within its scope.
Are 100 days abroad automatically allowed in the final year?
No. Section 15C normally permits 70 whole days absent and up to 30 additional days only where the Minister accepts exceptional circumstances. Part-days do not count as days for this rule. Spouse/civil-partner applications measure absence from the island of Ireland; standard applications measure absence from the State. This planner checks only the threshold you enter, not your travel history.
Does the citizenship clock start when I get Stamp 4?
Not necessarily. Earlier reckonable residence, including qualifying Stamp 1 or Stamp 1G time, can count. The Stamp 4 employment upgrade and citizenship residence test are separate, so enter their actual start dates separately.
