Most citizenship applications that fail do not fail on character or paperwork. They fail on the count. The residence test for naturalisation is precise and unforgiving: 5 years of reckonable residence within the last 9, ending with 1 continuous year immediately before you apply. Every day is counted, only qualifying stamps count, and a single undocumented gap between permissions can pull the whole application below the line.
This page is the eligibility check that comes first, and it is deliberately separate from the application itself. We run your immigration history through the official residency calculator, confirm which of your stamps are reckonable, count your absences in the final year, and weigh the standard 5-year route against the 3-year marriage route and any birth or descent entitlement you may already hold. You leave knowing exactly where you stand, and if you are short, exactly when you will qualify.
Made for people like you
Permit holders near the 5-year mark
Your years on Stamp 1 employment permits and on Stamp 4 all count, so you want to know the precise date your reckonable residence hits 5 years.
Spouses of Irish citizens
You may reach citizenship 2 years sooner through the marriage route. We check whether the 3-year residence and 3-year marriage tests both line up.
Anyone with gaps or student years
Time on Stamp 2, travel, or a lapse between IRP registrations. If you cannot say with certainty that you qualify, this is the check to run first.
People who may already be Irish
A parent or grandparent born in Ireland can mean you are a citizen already, or one register entry away, with no naturalisation needed at all.
Do you qualify?
Eligibility turns on three things: enough reckonable residence, on qualifying stamps, ending with a clean final year. Get all three and you can apply. Miss one and the €175 fee is lost, because there is no refund for an application that is short or ineligible.
You are likely eligible if
- You have 5 years of reckonable residence within the last 9: 365 continuous days immediately before applying, plus 1,460 days within the 8 years before that
- That time is on qualifying stamps only. Stamp 0, Stamp 1 including all employment permits, Stamp 1A, Stamp 1G, Stamp 3, Stamp 4, Stamp 5 and Stamp 6 all count
- You were outside Ireland for no more than 70 days in the 12 months before you apply, with up to 30 further days possible only for exceptional reasons
- Your permission never lapsed. Every IRP registration runs into the next with no undocumented gap
- You are 18 or over, of good character, and intend to keep living in Ireland after naturalisation
- Or, on the marriage route, you have been married to an Irish citizen for 3 years and have 3 years of reckonable residence on the island of Ireland
You are not eligible yet if
- Your total relies on student time. Stamp 2 and 2A do not count, with only limited discretion for young adults who arrived as children
- You were outside Ireland for more than 100 days in the final year. The application is ineligible with no discretion whatsoever
- You have an undocumented gap between permissions. Even a short lapse is not reckonable and can make you ineligible
- Your time here was spent awaiting an international protection decision. Residence only counts from the date status was granted
- You are counting on a date in the future. If you are short, the honest answer is to wait until you genuinely qualify rather than lose the fee

How the journey works
- 01
Map your immigration history
Day 1We list every stamp in your passport and every IRP registration date, from the day you arrived to today. This is where the count really lives, and where most people are quietly a few months out.
- 02
Run the official residency calculator
Day 1We put your history through ISD's own naturalisation residency calculator, counting only reckonable stamps. Student Stamp 2 and 2A time is stripped out, overlapping stamps are counted once, and any lapse between permissions is flagged.
- 03
Count the final-year absences
The 12 months before you apply must be continuous, with no more than 70 days abroad, extendable to 100 only for exceptional reasons. Departure and return days do not count as absences, which often rescues a borderline case. We build the travel log with you.
- 04
Weigh every route you might have
Standard 5-year, the 3-year marriage route, or an existing entitlement by birth or descent that means no application is needed at all. We tell you which is fastest and cleanest for your exact history.
- 05
Get a straight answer, and a date
OutcomeYou leave knowing whether you can apply now, or the precise date your reckonable residence reaches the threshold, plus a list of the proofs you will need for each year. Only then does it make sense to spend the €175.
What to gather
Start collecting these early. Weak or missing documents are the most common avoidable cause of delays and refusals.
IRP cards, current and expired
The core record of your reckonable residence. Every registration date matters
All passports, current and old
The landing stamp and every immigration endorsement help reconstruct your history
A list of your absences
Every trip in the final 12 months, so the 70-day count can be checked
One strong official proof per year
Bank statement, Employment Detail Summary, DSP contribution statement or employer letter, worth 100 points
Supporting residence proofs
Utility bill, phone bill or tenancy agreement, worth 50 points; two to three documents per year
Marriage certificate, on the spousal route
Plus proof of your spouse's Irish citizenship, if you are checking the 3-year route
Parent or grandparent birth certificates
If an Irish-born parent or grandparent means you may already be a citizen
Every case is different. We confirm your exact list at consultation.
What it costs
| Item | Cost | Notes |
|---|---|---|
| Eligibility check | Fixed fee | Agreed up front at booking. The official residency calculator itself is free to use. |
| Naturalisation application, later | €175 | Paid only if and when you apply. Non-refundable, with no waivers, so the count must be right first. |
| Certification fee on approval | €950 | Paid after approval, before the ceremony. €200 for minors and for a surviving spouse or civil partner. |
There is no fee to check whether you qualify, and every reason to. The €175 application fee is lost on an application that is short or ineligible, which is exactly the mistake an eligibility check exists to prevent.

Your eligibility answer
Days
Most residence questions can be answered as soon as we have your full stamp and IRP history.
The date you qualify
Calculated
If you are short, we give you the exact date your reckonable residence reaches 5 years in the last 9.
Application, once eligible
Online
Filed on the ISD online portal with the €175 fee, only after the count is confirmed.
Decision
~8 months
The median for 2024 and 2025 once you do apply. Most applications are decided within 12 months.
Why applications get refused
Most refusals are preventable. These are the patterns we see and design out of every application.
Counting student time as reckonable
Stamp 2 and 2A years feel like residence, but they do not count towards naturalisation. Applicants who include them can be a year or more short without realising it.
Avoid it: Start the reckonable clock from your first qualifying stamp, usually Stamp 1G, Stamp 1 or Stamp 4, and count from there.
An undocumented gap between permissions
A lapse between an expired IRP and its renewal is not reckonable, and can make the whole application ineligible rather than merely shorter. ISD tells applicants to check every IRP date.
Avoid it: Review your registration history end to end, and in future renew your IRP up to 12 weeks before expiry so permission never lapses.
Too many days abroad in the final year
The final 12 months allow 70 days of absence, up to 100 only for accepted exceptional reasons. Over 100 days the application is ineligible with no discretion, and the fee is lost.
Avoid it: Keep a travel log for the whole final year before you apply. Departure and return days are not counted as absences.
Assuming marriage makes you Irish
Marrying an Irish citizen does not confer citizenship. It only shortens the residence requirement to 3 years, and only where the 3-year marriage and living-together tests are also met.
Avoid it: Check both halves of the marriage route, the residence and the marriage duration, before assuming it is the faster path.
Applying on a date you have not reached
Filing a few weeks before your reckonable residence genuinely reaches 5 years makes the application ineligible, and the €175 is gone.
Avoid it: Confirm the exact qualifying date first, then file on or after it. Waiting a few weeks is far cheaper than losing the fee.
Common questions
How do I know if I have enough reckonable residence?+
You need 5 years of reckonable residence within the last 9, made up of 365 continuous days immediately before you apply plus 1,460 days within the 8 years before that. Only qualifying stamps count: Stamp 0, Stamp 1 including employment permits, Stamp 1A, Stamp 1G, Stamp 3, Stamp 4, Stamp 5 and Stamp 6. Student Stamp 2 and 2A time, undocumented gaps and time awaiting a protection decision do not count. We run your exact history through the official residency calculator so there is no guesswork.
Which immigration stamps are reckonable for citizenship?+
Stamp 0, Stamp 1 including time on any employment permit, Stamp 1A, Stamp 1G, Stamp 3, Stamp 4, Stamp 5 and Stamp 6 all count as reckonable residence. Stamp 2 and 2A student time does not count, and neither do undocumented gaps between permissions or time spent awaiting an international protection decision.
Is the 70-day absence limit for every year or just the final year?+
Just the final year. The 70-day absence limit applies only to the 12 months immediately before you apply, extendable to 100 days for exceptional reasons and never beyond. The earlier four years are not subject to a per-year absence cap; they simply have to add up to four years of reckonable residence within the surrounding 8-year window.
Could I already be an Irish citizen without applying?+
Possibly. If you were born on the island of Ireland before 1 January 2005, or born anywhere to a parent who was born in Ireland, you are already an Irish citizen and go straight to a passport. A grandparent born in Ireland can also make you eligible through the Foreign Births Register. We check any Irish parentage before assuming you need naturalisation at all.
What proof of residence will I need for each year?+
Each year you claim needs 150 points of residence proof: at least one strong official document worth 100 points, such as a bank statement, an Employment Detail Summary, a DSP contribution statement or an employer letter, plus supporting documents worth 50 points each, such as a utility bill or tenancy agreement. Identity is proved once, with a certified colour copy of your passport biometric page scoring the full 150 identity points. We check you can actually obtain the proofs before you apply.
What does the eligibility check cost, and why do it?+
The official residency calculator is free, and our check is a fixed fee agreed at booking. The reason to do it is simple: the €175 application fee is non-refundable, and an application that is even slightly short or has an undocumented gap is refused with the fee lost. A check before you file is the cheapest insurance there is.
