Ireland SARP Tax Relief for US Assignees

As of January 2026, a US employee assigned to Dublin on a €250,000 package can have €37,500 of that pay disregarded for Irish income tax under Ireland's Special Assignee Relief Programme (SARP). That slice is worth €15,000 of Irish income tax at the 40% rate. Miss the employer certification window, treat a remote job as an "assignment," or assume the US saving clause disappeared, and the same paycheck still faces Irish income tax, USC, and a US Form 1040.

This is a supporting playbook for assigned W-2 operators, not a second Ireland country guide. For the broader visa, remittance-basis, and cost-of-living picture, start with the Ireland US expat tax and visa guide. The rest of this article is the SARP math, the 2026 €125,000 bar, and the US forms that still sit underneath it.

Primary reader: a US citizen (or green-card holder) being transferred to an Irish employer or Irish affiliate. Secondary notes cover trailing spouses, families with school costs, and founders who will not qualify because nobody assigned them.

What is Ireland SARP, and who actually qualifies?

SARP is Irish income-tax relief for certain employees assigned into Ireland. It is not a digital-nomad visa, not a remote-work loophole, and not a way for a US citizen to stop filing a US return. Irish Revenue's own programme page states that you must be assigned by a relevant employer to work in Ireland for that employer or an associated company, and that the relief applies to assignments in tax years 2012 through 2030.

A relevant employer is a company incorporated and tax resident in a country that has a double tax agreement or a tax information exchange agreement with Ireland. The United States qualifies. The associated-company test uses section 432 of the Taxes Consolidation Act 1997, so group org charts matter more than a job title on LinkedIn.

The 2026 condition list, in plain English

Revenue's conditions page (published 22 January 2026) requires all of the following:

1. You arrive in Ireland in a tax year from 2012 to 2030 at the employer's request to perform duties in Ireland for that employer or an associated company.
2. Immediately before the assignment, you worked outside Ireland for that employer for at least six months.
3. You perform duties for at least 12 consecutive months from the first assignment date.
4. You were not Irish tax resident for the five tax years immediately before the arrival year.
5. You are Irish tax resident for every year you claim the relief.
6. Your basic salary is at least €125,000 a year, excluding bonuses, commissions, benefits, and share-based pay.
7. You hold a PPSN.
8. The employer certifies entitlement to Revenue, normally within 90 days of arrival.

The €125,000 floor is the 2026 change. Ireland's Budget 2026 summary (7 October 2025) extended SARP to 31 December 2030 and raised the minimum income threshold for new entrants from €100,000 to €125,000. Arrivals who first showed up before 2026 keep the older eligibility bar that applied to their arrival year.

Data note: thresholds and certification rules were checked against Revenue.ie and the Budget 2026 summary in September 2026 and can change in a later Finance Act.

How much Irish tax does SARP actually remove?

Relief is a "specified amount" that is disregarded for Irish income tax only. Revenue's calculation page and Tax and Duty Manual Part 34-00-10 use this formula:

(A − B) × 30%, where A is relevant Irish employment income capped at €1,000,000, and B is €125,000 if you arrive in 2026 or later (€100,000 if you arrived in 2023–2025).

A includes bonuses, commission, benefits in kind, and share-based pay. A excludes expenses, amounts not assessed to tax in Ireland, pension contributions that already got relief, and income on which you claim Irish double-tax relief for non-refundable foreign tax. That last exclusion is the trap for split-payroll packages: if part of the pay stays on a US payroll and Ireland gives a credit, that slice may drop out of A and shrink SARP.

Revenue is explicit: the specified amount is not exempt from USC. It is also not exempt from PRSI unless an EU regulation or a bilateral social-security agreement takes you out of Irish PRSI. The US–Ireland totalization agreement can do that for a genuine detached worker, which is a separate form process from SARP.

Irish income tax, USC, and credits around the relief

As of Budget 2026, income-tax rates and bands did not change: 20% up to €44,000 for a single person, then 40% on the balance. A married one-income couple gets a €53,000 standard-rate band. The single-person credit is €2,000 and the employee (PAYE) credit is €2,000. Those credits still apply after SARP; the relief only shrinks the income that hits the 20%/40% calculation.

USC for 2026 (standard rates) is 0.5% on the first €12,012, 2% from €12,012.01 to €28,700, 3% from €28,700.01 to €70,044, and 8% above €70,044. On a €250,000 salary that is roughly €16,031 of USC whether or not SARP applies. Do not sell yourself a "52% headline rate" story without separating income tax, USC, and PRSI.

Employee Class A PRSI is 4.20% through 30 September 2026 and 4.35% from 1 October 2026 on weekly income above €552 (subclass A1), per the Department of Social Protection. Employer A1 is 11.25% then 11.40%. If a US Certificate of Coverage keeps you in US Social Security instead, those Irish employee PRSI rates should not stack on the same earnings — but you then owe the US FICA stack unless another exception applies.

2026 arrival package (illustrative)	Specified amount (SARP)	Irish IT saved at 40%	Still due on the full package
€125,000 base, no bonus	€0 (A equals B)	€0	Income tax, USC, PRSI/FICA
€180,000 all Irish-assessed	€16,500	€6,600	USC on €180,000; PRSI unless CoC
€250,000 all Irish-assessed	€37,500	€15,000	USC on €250,000
€400,000 all Irish-assessed	€82,500	€33,000	USC on €400,000
€1,200,000 (A capped at €1m)	€262,500	€105,000	Income tax still due on the uncapped excess; USC on the full amount

The €125,000 row is the gotcha for candidates who hear "SARP starts at €125k" and expect an automatic cut. Eligibility at exactly €125,000 of basic salary is not the same as a positive specified amount. You need A above B. A bonus can lift A even when base is €125,000, but base still has to clear the eligibility floor without counting that bonus.

Do I lose SARP if HR files the certificate late?

Yes, or you lose a year. The default rule is employer certification to Revenue within 90 days of arrival, through the eSARP portal on ROS (in place since 1 January 2024). Budget 2026 also moved the annual employer SARP return deadline from 23 February to 30 June after the tax year.

For arrivals on or after 1 January 2026, certification after day 90 can still preserve eligibility if it is in by day 180 — but Revenue then withholds relief for the first year of residence, and the remaining claim is a maximum of four consecutive years instead of five. That is not a paperwork footnote. On a €250,000 package it is the €15,000 Irish income-tax cut for year one, gone.

You are a chargeable person for Irish income tax if you claim SARP, which means an annual Irish return even if PAYE already ran through payroll. Families should budget for that compliance cost the same way they budget Dublin rent.

Do I still owe Irish tax if I fly in under 183 days?

SARP requires Irish tax residence for every claim year. Revenue's residence page says you are resident if you are present 183 days or more in a calendar tax year, or 280 days or more across the current year plus the prior year. Presence of 30 days or less in a year does not create residence, and those days drop out of the look-back count.

A day counts if you are in Ireland for any part of the day, with narrow airside and weather-delay exceptions. Split-year and election-to-be-resident rules exist for arrival years, but they are a separate Revenue process. Do not assume a Monday–Thursday Dublin roster keeps you non-resident while you also claim SARP. The programme and the day-count have to line up.

Spain's inbound Beckham-style regime is a cousin, not a substitute: it is a different statute, a different day-count, and a different US treaty overlay. If you are comparing EU inbound packages, read the recent Spain Beckham Law 24% flat-tax guide as a parallel, then come back to SARP's assignment-and-salary tests.

Do I still owe US tax if SARP cuts the Irish bill?

Yes. The US–Ireland income-tax treaty includes a saving clause. Treasury's technical explanation of Article 1 is the usual US rule: the United States generally keeps the right to tax its citizens as if the treaty were not in force, with listed exceptions. SARP does not punch a hole in that clause. You still file Form 1040 on worldwide income.

The useful US tools are the foreign tax credit on Form 1116 and, in some years, the foreign earned income exclusion on Form 2555. As of tax year 2026, the IRS maximum FEIE is $132,900 per qualifying person. Dublin is a listed high-cost housing location in IRS Notice 2026-25, with a $42,600 full-year housing-expense limitation versus the general $39,870 cap. The housing exclusion still has a 16% base amount ($21,264 for a full 2026 year), so the extra Dublin room is real but not unlimited.

In a high-tax country, electing FEIE often wastes Irish tax that would have been creditable. Irish income tax remaining after SARP is still a creditable income tax for Form 1116 purposes if it meets the usual tests; USC and PRSI are not automatic FTC items and should not be dumped into the credit without a tax advisor mapping each levy. If you exclude income under section 911, you generally cannot credit foreign tax on the excluded slice. For a €250,000 Dublin salary, run both models before payroll locks a code.

More on that fork sits in the Expat Tax & Finance library, including the FEIE-versus-credit comparison linked above and the US tax treaty saving-clause explainer.

Social Security versus PRSI on a five-year assignment

The US–Ireland Social Security agreement entered into force on 1 September 1993. SSA's pamphlet rule is the standard detached-worker pattern: if your US employer sends you to work for that employer or an affiliate in Ireland for five years or less, you generally stay in US Social Security and are exempt from Irish coverage, proved with a Certificate of Coverage. Stay longer, or be hired locally with no US home-country coverage, and Irish PRSI is the default on Irish work.

That choice changes take-home pay more than SARP does at the €125,000 eligibility line. It also changes future benefit credits. A CoC that keeps you in US FICA means you are not building Irish PRSI weeks; SSA warns that workers exempted from Irish coverage generally cannot claim Irish unemployment, maternity, occupational-injury, or health-insurance benefits tied to those contributions. Price private health cover before you celebrate a FICA-only stack.

For the form path, use the US totalization agreement guide and SSA's Ireland agreement materials, not a verbal HR promise.

What should an assigned family actually set up?

SARP is a tax calculation. Cash flow is the account map that has to survive two tax authorities, two payrolls, and Dublin rent that often exceeds the IRS housing cap.

• Keep a US brokerage you can still trade from Ireland. Charles Schwab is the common expat-friendly path for USD investing and ATM access; confirm your country of residence is on the international account list before you change your address.
• Do not close US bank access until the first Irish PAYE cycle has actually landed. Assignment start dates slip.
• Track every foreign account against the FBAR $10,000 aggregate peak. FinCEN Form 114 is separate from Form 1040. An Irish current account plus a US account does not create an FBAR by itself; the Irish (and other foreign) accounts do once the $10,000 test is met.
• Form 8938 (FATCA) rides with the income-tax return, including extensions. Living-abroad thresholds are higher than US-resident thresholds; confirm the current Instructions for Form 8938 for your filing status before you skip the form.
• If the package includes an Irish occupational pension or share plan, map PFIC, Form 3520, and employer-plan reporting before you "just enroll." Those are different articles; the mistake is treating them as SARP side quests.

Retirees and independent contractors are usually outside SARP. A pension-only move is an Irish residence and remittance-basis problem, not an assignee relief problem. A freelancer who incorporates in Delaware and invoices an Irish customer is not "assigned."

Families should ask payroll whether school fees and home-leave flights will be run as tax-free SARP travel/education items or as taxable BIK. Revenue says qualifying assignees can receive, tax free, certain travel expenses and costs associated with a child's education in the State. "Certain" is not "all tuition, uncapped." Get the category in writing.

Assignment checklist before you accept the letter

1. Confirm you already worked for the sending employer outside Ireland for six months, with dates that survive a Revenue query.
2. Confirm the Irish host is the same employer or a section 432 associated company, not a customer.
3. Put basic salary at or above €125,000 in the contract, separate from bonus and equity.
4. State the intended assignment length (12 months minimum for SARP; five years or less if you want the usual US CoC path).
5. Name the ROS/eSARP filer and the day-90 certification date in the onboarding plan.
6. Model Irish income tax with and without the specified amount, plus full USC.
7. Model US Form 1116 versus Form 2555 on the same euro figures, using a consistent FX method.
8. Decide Social Security coverage and start the Certificate of Coverage request before the first Irish payday.
9. Open or retain US brokerage and banking, then list every Irish account for FBAR/8938.
10. If you are comparing inbound EU regimes, score SARP against Beckham-style programmes on assignment tests, not on a single headline percentage.

Conclusion

SARP is a five-year (or four-year, if certification is late) Irish income-tax haircut for assigned employees who clear a €125,000 basic-salary floor in 2026 and keep Irish tax residence. It does not remove USC, does not automatically remove PRSI, and does not silence the US saving clause. The cash-flow win is real on a €180,000–€400,000 Dublin package if HR files on time and the US return credits the remaining Irish income tax instead of throwing it away under FEIE.

If you are not being assigned, stop trying to wear this regime. Use the Ireland country guide for residence and visas, and use the tax-credit tools for the US return you still have to file.
