The decision to relocate to Thailand as an Irish software developer is simultaneously a tax opportunity and a bureaucratic puzzle. You have skills that command premium salaries in Dublin, but the cost of living in Bangkok is roughly one-third of what you'd spend in Ireland — the math on geographic arbitrage is straightforward. The visa path is less obvious.
For Irish software developers working remotely for Dublin or international tech firms, the LTR Visa's Work-From-Thailand category is the cleanest legal framework Thailand offers. It grants a 10-year stay, annual reporting instead of quarterly 90-day renewals, and access to a fast-track work permit if you want the option. The bar to entry is high, but most developers at mid-to-senior level clear it easily.
Where Irish applicants typically stumble is income documentation. Your payslips come from an Irish employer and display your salary in EUR, not USD. Your employer's corporate financials are filed with the Irish Companies Registration Office and may show revenue in multiples of currency you're not thinking in. And Irish tax complexity — the Revenue Commissioners, PAYE taxes, pension contributions — introduces friction that developers moving from the US don't face.
This guide walks through the LTR Visa process as it applies specifically to Irish software developers, with exact income documentation requirements, Irish tax context, and the specific employment verification steps that matter to the Thai BOI.
Why the LTR Visa Work-From-Thailand Category Is Built for Remote Developers
The LTR Visa framework has four tracks. For Irish software developers, the Work-From-Thailand Professional category is the natural fit. The Highly Skilled Professional category (for developers working for Thai companies) exists but is substantially less common among Irish nationals just relocating.
The complete LTR requirements — financial thresholds, annual reporting burdens, dependent eligibility — are covered in full in the Thailand LTR Visa Complete 10-Year Guide. What's specific to Irish developers is how you document your income and employment, and how your Irish tax status interacts with a Thailand long-stay visa.
LTR Work-From-Thailand: The Core Requirements for Irish Software Developers
The Work-From-Thailand category requires USD 80,000/year (or USD 40,000/year plus a master's degree) earned from a foreign company meeting specific size thresholds.
The employer revenue requirement: Your employer must have total revenue of at least USD 150,000,000/year for at least 3 of the past 5 years. For an Irish developer at a Dublin tech firm, a mid-market SaaS company, or a software consultancy, this is often the deciding factor.
Companies that typically clear this threshold include:
- Dublin-based tech giants (Google, Facebook, Apple, Microsoft, Amazon engineering offices)
- Multinational software firms with Irish subsidiaries (SAP, Oracle, Salesforce, ServiceNow)
- Mid-market to large Irish SaaS firms (like Intercom, Stripe's Dublin engineering team, or similar €50M+ revenue companies)
- UK/EU tech firms with English-speaking engineering teams hiring Dublin developers
Companies that do NOT typically clear this threshold include startups (Series A or B stage), boutique consultancies with under €20M/year revenue, and small agencies. If your employer is a startup or small firm, the LTR Work-From-Thailand category likely won't work — and you'd need to reassess whether the DTV (Digital Nomad Visa) is a better fit.
Irish Income Documentation: W-2s Don't Exist Here — Here's What Works Instead
This is the critical friction point. Irish employment doesn't generate W-2 forms (those are US IRS documents). The Thai BOI needs to verify your income has been consistent for the past 2 years, and it needs that documentation in a format they can cross-check against company financials.
Required documents for Irish software developers:
- Employment contract — Your original employment agreement, signed by you and your Irish employer. Must include: your job title, start date, base salary in EUR (we'll convert to USD), reporting structure, and duration (if fixed-term, must show renewal or permanent status).
- 3–6 months of Irish payslips — Recent payslips from your Irish employer showing gross salary, tax deductions (PAYE, PRSI), and net payment. These must be official payslips, not screenshot estimates. The date range matters: they should be from the most recent 3 months to demonstrate current employment status.
- Revenue Commissioners tax clearance certificate — Your Irish tax compliance certificate from the Revenue Commissioners. This proves you've filed your Irish income tax returns and have no outstanding liabilities. The BOI uses this to verify you're not flagged by Irish tax authorities.
- Bank statements showing consistent salary deposits — 6 months of bank statements from your Irish bank account showing regular monthly deposits matching the payslip amounts. These should clearly show employer name and payment frequency (usually monthly or bi-weekly).
- Company financials (employer's audited accounts) — Your employer's last 2 years of audited financial statements, filed with the Irish Companies Registration Office (or UK equivalent if a UK firm). The statements must clearly show total revenue exceeding USD 150M/year. You can obtain these from the CRO website for free — they're public documents.
- Company registration certificate — Certificate of incorporation from the CRO or Companies House (for UK employers).
The currency conversion is automatic: the Thai BOI accepts payslips and contracts in EUR and cross-checks against USD 80,000/year using the contemporaneous exchange rate (typically they use a 6-month average or the rate at time of application).
Common documentation mistakes Irish developers make:
Submitting payslips with PAYE and PRSI deductions but no gross salary breakdown. The BOI needs to see your gross annual salary to verify the USD 80,000 threshold. If your payslips don't clearly separate gross from net, attach an official employer letter stating your annual gross salary in both EUR and USD equivalent.
Using unaudited company financial statements. If your employer is a private company, they may file abbreviated accounts with the CRO. The BOI will request full audited financials showing detailed revenue figures. If your employer is small enough to file micro-company accounts, those won't be sufficient — and the LTR may not be viable for you.
Submitting a contract dated more than 2–3 years ago without evidence of renewal or continued employment. If your employment contract was signed in 2023 but you're applying in 2026, you need payslips covering the entire 2024–2026 period to show continuity. A single month-old payslip won't bridge a 2-year gap.

The Irish Tax Angle: Understanding Your Status as an LTR Visa Holder
Relocating to Thailand does not automatically sever your Irish tax residency. The Revenue Commissioners determine Irish tax residency based on physical presence (183+ days/year in Ireland), family connections, and accommodation ties. If you move to Thailand and spend fewer than 183 days in Ireland annually, you will likely be classified as non-resident for Irish tax purposes, which is favorable.
Key Irish tax implications of holding an LTR Visa and working remotely for an Irish employer:
Irish tax non-residency. If you're non-resident in Ireland and working for an Irish employer, your Irish employment income is still assessable by the Revenue Commissioners as Irish-source income. The fact that you're physically in Thailand doesn't exempt it. You file Irish tax returns on your worldwide income as a non-resident, but you're entitled to foreign tax credits for taxes paid in Thailand.
Thailand tax on remitted income. Thailand's recent updates to remittance taxation can be confusing. Foreign-source income (including salary from an Irish employer) remitted to Thailand in the same calendar year it's earned is assessable in Thailand. If you earn EUR 80,000 in 2026 and remit it to a Thai bank account in 2026, you may owe Thai tax on that amount. However, the US-Ireland tax treaty and other bilateral agreements may provide relief — this is jurisdiction-specific and requires consultation with a specialist.
LTR Visa tax exemptions DO NOT apply to your employment income. The LTR Visa offers a tax exemption on foreign-source passive income (dividends, rental income, interest) remitted to Thailand — but not on employment salary. Your employment income is subject to both Irish and Thai tax scrutiny depending on your residency classification and the specific income year.
This is complex enough that you should not wing it. Engage a US expat tax professional (or UK/Irish equivalent — firms like Bright!Tax or Greenback Expat Tax handle Ireland-Thailand cases) to map your specific tax position before you make the relocation decision. The difference between correct planning and incorrect filing can easily exceed 10,000 EUR/year.
Employment Letter Requirements: What the BOI Actually Wants
The Thai BOI requires a formal employment letter from your Irish employer confirming your current role, salary, and expected duration of employment. This isn't a generic "letter of employment" you'd get for a bank. It needs specific elements:
- On official company letterhead — with company registration number and address visible
- Signed by an authorized officer — typically your manager or HR director (not an auto-signature or email confirmation)
- Job title and department
- Start date and type of employment (permanent, fixed-term, contract, etc.)
- Annual gross salary in EUR and USD equivalent — using the exchange rate at time of letter or a reasonable 3-month average
- Remote work authorization — explicit statement that your employer permits remote work from Thailand and recognizes your continued employment relationship while physically located abroad
- Expected duration — a statement that your employment is expected to continue for the duration of the LTR Visa (or at minimum 2+ years)
Many Irish employers will push back on the "remote work authorization" clause, claiming it's a legal liability issue or requires permission from corporate headquarters. Work with your HR team and explain that it's not agreeing to unlimited remote work — it's confirming that your current role (which you may already be performing remotely from a co-working space in Dublin) is compatible with being physically located in Thailand. Most will cooperate once they understand the ask.
Processing Timeline and LTR Steps for Irish Developers
The LTR Visa process runs in two phases, each with its own timeline:
Phase 1: BOI Endorsement
You submit your documentation to the Board of Investment through their online portal. Processing takes approximately 2 months from submission to approval. The BOI will request clarifications if documents are unclear — which happens in roughly 30–40% of applications. If they ask for revisions, you have 30 days to respond, which resets the clock.
For Irish developers, common BOI requests include:
- Certified English translation of your employment contract (if signed in Irish or with Irish-language clauses)
- Clarification on how your gross salary was calculated if payslips show significant deductions
- A letter from your Irish employer explicitly confirming that your role exists and is unchanged while you're in Thailand
- Most recent audited financial statements of your employer (if the ones you submitted are 18+ months old)
Phase 2: Visa Issuance
Once the BOI approves your application, you have 2 months to complete visa issuance. You'll submit your passport and supporting documents to the Thai BOI office at One Bangkok, or you can apply through the e-visa system (if it's available for your location). Visa processing typically takes 1–2 weeks after submission.
Total timeline: 2 months (BOI endorsement) + 1–2 weeks (visa issuance) = approximately 8–10 weeks from start to finish, assuming no requests for additional information.
Dependents: Partner and Children on the LTR Visa
If you're relocating with a spouse and/or children under 20, they can apply as LTR dependents on your main visa. The process and requirements are covered in the main LTR guide — but one Irish-specific note: if you're married to an Irish national, your marriage certificate (issued by the HSE Civil Registration Service) needs to be apostilled by the Department of Justice (or the relevant issuing body in Ireland) before submission to the Thai BOI. An unapostilled certificate will be rejected.
Each dependent visa costs 10,000 THB (approximately USD 280). Dependents require their own health insurance (or can be covered under your policy if it extends to family members), and they must be present in Thailand when their visa is issued.
The Cost Math: Is the LTR Worth It for an Irish Developer?
The LTR Visa isn't free. The Thai government fee is 50,000 THB (~USD 1,400). Health insurance is required and costs USD 1,000–USD 3,000/year depending on age and provider. If you have dependents, add 10,000 THB per dependent plus their health insurance.
Compare that to the Non-O Retirement Visa (which requires age 50+ and annual renewals) or the DTV (which is 10,000 THB but only 5 years with complex extension mechanics). For a developer earning USD 80k+/year and planning a 10-year Thailand stay, the LTR pricing is absolutely rational:
- 50,000 THB government fee (one-time)
- Health insurance: USD 1,500–2,000/year × 10 years = USD 15,000–20,000
- Issa pre-screening and application support: significantly lower than traditional agents
- Peace of mind from a 10-year legal certainty: priceless for someone serious about building a life in Bangkok
The DTV is cheaper upfront (10,000 THB) but requires managing two 180-day extensions per entry and hitting 90-day immigration reports quarterly. If you're not fundamentally committed to staying in Thailand long-term, the DTV is a reasonable trial run. If you're planning to build a life, establish a business, or invest in real estate, the 10-year LTR clarity is the smarter play.
Why Issa Matters for Irish Developers Applying for the LTR
The LTR Visa application process is document-heavy and geographically distributed: your Irish payslips and company financials are filed in Dublin, the Thai BOI expects them in a specific format in Bangkok, and you're physically applying from Thailand or Europe. Coordinating those three points requires structure.
Traditional visa agents charge 800 USD–2,500 USD and then hand you a checklist. Issa's approach is different: we manually pre-screen your Irish employment documentation against the BOI's exact current requirements before you submit a single document to the government. If your employment letter is missing a required clause, if your payslips don't clearly show gross salary, or if your employer's financial statements won't satisfy BOI review, we identify that before you pay the non-refundable 50,000 THB government fee.
For Irish developers specifically, we have direct experience with:
- Irish employer revenue verification through Companies Registration Office filings
- Irish tax documentation and Revenue Commissioners compliance letters
- Currency conversion and salary documentation for EUR-to-USD income thresholds
- Irish dependent documentation (marriage certificates, apostilles, civil registration)
We also carry a 100% money-back guarantee: if your application is rejected due to our error in pre-screening or guidance, we refund both our service fee and your government fees. That guarantee is backed by our confidence in the pre-screening process — and it transfers the financial risk from you to us, where it belongs.
Long-Tail FAQ for Irish Software Developers
Do I need to work in a specific tech industry (AI, fintech, etc.) to qualify for the LTR Work-From-Thailand category?
No. The Work-From-Thailand category doesn't restrict you by industry — only by employer size (USD 150M+ revenue) and personal income (USD 80k+). Whether you're a backend engineer at a Dublin financial services firm, a full-stack developer at a SaaS startup that happens to be large enough, or a data engineer at a tech consulting firm, the category doesn't discriminate. The Highly Skilled Professional category does have industry restrictions (AI, automation, biotech, medical, etc.) — but that's a different track and typically reserved for developers working for Thai companies.
What if my Irish employer won't provide a letter confirming remote work authorization from Thailand?
That's a negotiation, not a blocker. Many employers are hesitant to explicitly authorize work from Thailand due to perceived tax or legal complexity. Frame the request as confirmation of your current role and location-flexibility — not a new arrangement. If they still refuse, you may still be able to proceed: the BOI accepts an employment letter without the remote work clause, but it creates slight additional scrutiny. Issa can advise on whether to push harder with your employer or accept the added complexity. In rare cases, if your employer flatly refuses, the Highly Skilled Professional category (if you can find a Thai employer role) becomes the fallback.
Can I use contractor invoices or a 1099 instead of employment payslips if I'm self-employed in Ireland?
Only if you meet the criteria for a different LTR category. The Work-From-Thailand Professional category specifically requires employment with a foreign company meeting the USD 150M revenue threshold. Self-employed contractors and freelancers need to look at the Wealthy Pensioner or Wealthy Global Citizen categories (which require USD 40k–80k passive income plus investment in Thailand). Alternatively, the DTV Visa is the natural fit for freelancers and business owners.
How does the Irish-Thailand tax treaty affect my employment income while holding an LTR Visa?
The US-Ireland tax treaty exists, but there's no specific bilateral Ireland-Thailand tax treaty in force (as of 2026). Your Irish employment income will be subject to Irish tax as a non-resident (if you don't meet the 183-day threshold in Ireland) and potentially to Thai tax under Thailand's territorial taxation system. The interplay is complex and depends on specific income year, remittance timing, and your employment status. Consult a tax professional specializing in Ireland-Thailand taxation before making the relocation final. This is not a DIY decision — a single misclassification could cost thousands in back taxes.
What if my employer's revenue is close to USD 150M but doesn't quite hit it — can I still apply?
Technically, you don't qualify for the Work-From-Thailand category if your employer's revenue is below USD 150M for at least 3 of the past 5 years. The BOI is strict on this threshold because it's designed to filter for legitimate large multinationals. If your employer is at USD 145M, they won't accept it — and reapplying later with revised financials adds delay. However, the Highly Skilled Professional category may be available if your employer operates in a BOI-designated industry (digital technology, automation, etc.). Issa can review your employer's specific profile and advise on the best path forward.
Next Steps: Getting Your Irish Soft Developer LTR Application Started
The LTR Visa for Irish software developers is genuinely the cleanest 10-year legal pathway Thailand offers. The income bar is high, but most mid-level and senior developers clear it. The documentation is heavyweight, but it's systematic and transparent — no guessing, no political discretion, just a checklist and a timeline.
The win is having 10-year legal certainty without annual renewals, quarterly immigration reports, or the complexity of extensions. You leave Ireland, establish yourself in Bangkok, build a tech team or invest in a business, and know your visa status is rock-solid for a decade.
Start by getting your Irish employer to pull together the last 2 years of audited financial statements and your employment contract. Then apply via the Issa Compass app and get your documentation pre-screened before you submit to the government. The 8–10 week investment upfront is worth the 10-year certainty on the back end.
