Irish 52% marginal tax vs Bulgaria 10%: Dublin tech worker relocation 2026

Dublin's tech salaries are world-class. Dublin's take-home pay is not. Once you cross €70,044 of gross income, every additional euro is taxed at 40% income tax + 8% USC + 4.2% Employee PRSI = 52.2% marginal (rising to 52.35% from 1 October 2026 with the PRSI increase). A senior Dublin engineer on €140,000 hands €60,000+ back to Revenue Commissioners — 43% effective. A staff engineer on €250,000 hands €115,000+ back. Bulgaria's 10% flat PIT is the lowest in the EU. Bulgaria joined the eurozone on 1 January 2026 and Schengen on 1 January 2025. Dublin to Sofia is one daily Ryanair flight. This guide models three Dublin tech salary brackets — €80,000, €140,000, €250,000 — against the Bulgarian alternatives (EOOD director-dividend, freelancer with 25% expense deduction, employed via Bulgarian entity) and shows annual savings ranging from approximately €13,000 to €89,000 — before RSU and share-option upside.

Ireland 2026 Tax Rates — the Full Breakdown

Budget 2026 made two relevant changes: USC tier 3 was cut from 4% to 3%, and the tier 3 threshold rose from €25,760 to €28,700. The 8% top tier (kicking in at €70,044) was unchanged. The increase in Employee PRSI from 4.2% to 4.35% on 1 October 2026 nudges the top marginal rate up to 52.35%.

Income tax bands

USC tiers (2026)

PRSI

Employee PRSI Class A1 is 4.2% from 1 January 2026, rising to 4.35% from 1 October 2026. No upper limit. Self-employed Class S PRSI is 4.2% / 4.35% on net trade or profession income above €5,000.

The 52.2% / 52.35% marginal rate

Above €70,044, each additional euro of gross Dublin salary is taxed at:

• Income tax: 40%
• USC: 8%
• Employee PRSI: 4.2% (4.35% from October 2026)
• Total marginal: 52.2% / 52.35%

Add the employer's PRSI of 11.05% to see the all-in employment cost — an extra €1 of gross pay costs the Dublin tech employer €1.11 and delivers €0.476 to the employee. That gap is the structural argument for Dublin remote-working migration.

Bulgaria 2026 Tax — the Other Side

Two structural Bulgarian advantages stand out for Dublin tech workers:

• Flat 10% PIT regardless of income level. No 40% tier, no 52% combined marginal.
• Social security capped on notional income. Bulgarian social security is calculated on a notional €2,000/month gross base for self-employed and EOOD directors — well under €520/month combined contribution. Dublin's PRSI is uncapped at 4.2% of gross.

Three Worked Comparisons

All examples assume a single individual, full personal credits / allowances applied, base Irish tax credit of €2,000.

Example 1 — €80,000 gross Dublin tech salary

Annual saving (freelancer route): ~€13,000. Over 5 years: ~€65,000 of additional after-tax wealth.

Example 2 — €140,000 gross Dublin tech salary

Annual saving (freelancer route): ~€39,800. Over 5 years: ~€199,000.

Example 3 — €250,000 gross Dublin tech salary (staff / principal engineer)

Annual saving (freelancer route): ~€88,570. Over 5 years: ~€442,000 of additional after-tax wealth.

EOOD vs Freelancer — Which Bulgarian Structure?

Bulgarian PITA gives the option of two structurally different routes for an individual earning service-type income. The choice depends on income level, expense profile and ongoing commercial plans.

For a single Dublin tech worker contracting to one or two non-Bulgarian clients with low overheads, the freelancer route is typically the lower effective rate. For a tech worker building agency capacity, scaling team headcount or planning IP holding, the EOOD is the structural answer. We run the comparison for every Irish leaver based on actual income mix — the headline numbers above are the starting point, not the answer.

PAYE Exclusion Order — Continuing to Work for a Dublin Employer

If you want to continue your employment with a Dublin employer while physically based in Bulgaria, Revenue Commissioners may issue a PAYE Exclusion Order — an instruction to your Irish employer to stop Irish PAYE deduction. The conditions:

• You are non-resident for Irish tax purposes;
• All duties of the employment are performed outside Ireland;
• The employment is not a "public sector" or government-service role.

Apply via your tax agent or directly to Revenue. Once issued, the Irish employer stops PAYE and you become responsible for Bulgarian tax on the income. The Irish PRSI position depends on a separate determination — if you are subject to Bulgarian social security (likely, since you live in Sofia and work from there), Irish PRSI also stops. Your Bulgarian EOOD or freelancer status will trigger Bulgarian social security.

RSU and Share-Option Planning

For US-listed tech companies (Meta, Google, Stripe, Microsoft, Amazon — the biggest Dublin employers), RSU vesting is a major component of total compensation. The tax position changes materially with the move.

Ireland

• RSU vesting = income tax + USC + PRSI at vest (52.2% marginal).
• Subsequent disposal of vested shares = 33% CGT on gain above the vest-date value.
• Effective on a €100,000 grant vesting at €120,000 and sold at €150,000: ~€52,200 (PAYE+USC+PRSI on €120k vest) + ~€9,900 (33% CGT on €30k gain) = ~€62,100 / 41.4% all-in.

Bulgaria

• RSU vesting (post-departure, duties performed in Bulgaria) = 10% Bulgarian PIT at vest.
• Subsequent disposal of vested shares: 10% PIT on US-listed (most US tech); 0% on EU/EEA-regulated-market listings (rarer).
• Same €100,000 grant vesting at €120,000, sold at €150,000: €12,000 (10% PIT on vest) + €3,000 (10% PIT on €30k gain) = €15,000 / 10% all-in.

Saving per €100,000 of RSUs through the full cycle: ~€47,000. For a senior engineer with €200,000+/year of vesting RSUs, the move to Bulgaria saves €100,000+ in tax annually on the equity component alone.

The Sofia Lifestyle Trade

• Single-person Sofia cost of living: €1,500–€2,000/month (Dublin: €3,500–€4,500).
• Family cost of living (2 adults + 1 child, central Sofia): €3,000–€4,500/month (Dublin: €6,000–€9,000).
• International schools: Anglo-American School Sofia, British School Sofia, AS Sofia — fees €8,000–€18,000/year (Dublin equivalent: €14,000–€25,000+).
• Direct flights: Sofia ↔ Dublin daily (Ryanair); under 4 hours.
• Climate: 280+ days of sun per year vs Dublin's ~120; ski season Dec–Mar at Borovets / Bansko / Vitosha (45 min from Sofia).
• English proficiency: high among Sofia, Plovdiv, Varna professionals; everyday services widely accessible.

For a Dublin tech worker accustomed to commuting an hour each way, a 15-minute Sofia commute and 50% lower cost base is materially life-changing — even before the tax saving.

Bulgarian Arrival in 90 Days

For an EU citizen, the move is administratively simple:

1. Arrive in Bulgaria with passport / ID card. Register your address within the first week.
2. Apply for EU citizen residence certificate at the Migration Directorate. Submit proof of resources, employment / self-employment basis, accommodation, health insurance.

4. Open Bulgarian bank account. Most banks accept on day 1 of arrival.
5. Register your EOOD or freelancer status (typically 7–10 working days).
6. File for Bulgarian tax residency certificate after 183 days physical presence (or earlier if centre of vital interests is substantively documented).
