Irish consultants face a specific problem in the LTR application process: the visa was designed for salaried employees and asset-wealthy retirees. Project-based, client-retainer, and lump-sum consulting income doesn't fit the standard W-2 pattern that Thai immigration officers expect.
The LTR Visa is Thailand's 10-year Long-Term Resident program, accessible through the Board of Investment (BOI). For a consultant, it's significantly more valuable than the 5-year DTV if you can clear the income threshold — it offers annual reporting instead of 90-day checks, no re-entry permits needed, and tax exemption on foreign-sourced income remitted to Thailand. The catch is that your consulting income structure has to square with the BOI's documentation requirements.
Most Irish consultants fail at the income proof stage because they're presenting irregular monthly deposits from multiple clients when the BOI wants to see stable, verifiable, 2-year-continuous income. That mismatch isn't a hard no, but it requires careful preparation. This guide walks through how consulting income actually translates into LTR eligibility and which category fits your specific income structure.

The LTR Application Structure (Pillar Reference)
The LTR Visa application runs in two stages through the Board of Investment. The first stage is BOI endorsement, which takes approximately 2 months. After endorsement is approved, you move to visa issuance. The full timeline from initial BOI application to final visa issuance is approximately 4 months. See the Complete LTR Visa Guide for universal application flow and all four category definitions.
Which LTR Category Fits Irish Consultants?
Irish consultants split between two LTR tracks depending on income volume and employment structure: Work-From-Thailand Professional and Highly Skilled Professional.
Work-From-Thailand Professional: For Independent Consultants
This is the default track for consultants who are self-employed or operating as director/shareholder of a consultancy entity. The eligibility test is straightforward on paper:
- Personal income of USD 80,000/year (past 2 years)
- OR income USD 40,000–80,000/year plus a master's degree
- Work experience of 5+ years in your field
- Contract or engagement with foreign clients (does not require a single employer)
- Health insurance with minimum USD 50,000 inpatient coverage
Here's the friction: the "contract with foreign clients" language suggests employment. In practice, the BOI accepts consulting arrangements where you're billing multiple clients through invoices, contracts, and retainer agreements. The 2025 policy relaxation opened more flexibility here, moving away from a strict "single employer" requirement toward a broader "sustained consulting income from verifiable sources" standard.
For a USD 80,000+ independent consultant, the path is clear. The problem sits at the documentation boundary.
Highly Skilled Professional: For Specialists in Targeted Industries
If your consulting sits within Thailand's BOI target sectors — digital technology, automation, biofuels, medical, agriculture/biotech — you qualify as a Highly Skilled Professional. The financial bar is the same (USD 80,000/year or USD 40,000 + master's degree), but the employment requirement is stricter: you must have a formal engagement with a Thai or international organization in that sector.
This track makes sense if you're consulting for a Bangkok-based tech startup, a multinational biotech firm's regional office, or a digital agency. If you're a pure independent consultant to global clients, Work-From-Thailand is cleaner.

Consulting Income Proof for the LTR: The Critical Friction Point
This is where Irish consultants stumble. The standard income documentation for a salaried W-2 employee is straightforward: employment contract, 2 years of tax returns, 2 years of pay stubs, and a bank statement showing consistent monthly deposits.
For a consultant, that framework doesn't exist. You have irregular invoice payments, variable monthly income, client gaps between projects, and (often) lumpy deposits that don't align with calendar months. The BOI reviewers are trained to flag this as "unstable income" or "insufficient documentation of sustained employment."
The solution is not to hide this reality; it's to present it strategically. Here's what actually works:
Document 1: The 2-Year Tax Return Package
For Irish consultants, this means your Revenue Commissioners Self-Assessment tax returns (Form SA) for the past 2 full tax years (January–December, not Irish fiscal year April–April). The BOI wants to see:
- Net taxable profit from your consulting business (Schedule C equivalent)
- A clear line showing the business generated revenue above USD 80,000/year
- The same income level sustained across both years (ideally growth, not decline)
A single high-income year followed by a drop does not pass scrutiny. The BOI is checking for income stability, not windfall gains. If you had a strong 2024 and a weaker 2025, you'll need to demonstrate why the 2025 slowdown is temporary (major new client signed, seasonal business model, portfolio transition) and show a concrete 2026 forward pipeline.
Document 2: The Annotated Bank Statement Overview (12 Months)
This is the strongest document for consulting income because it shows actual, verifiable cash flow. Pull your last 12 months of bank statements (covers both the current and prior year tax submission periods) and create an annotated summary with these columns:
- Date of deposit
- Deposit amount (in USD or EUR, show both if possible)
- Client name (redact if NDA-sensitive; use "Client A", "Client B", etc.)
- Invoice number corresponding to that deposit
- Project or engagement type
Why this matters: the BOI reviewer is visually confirming that money is actually flowing from external clients into your account on a regular basis. Irregular deposits raise questions; regular deposits every 4–6 weeks from 3–5 distinct clients signal a legitimate consulting operation. If you're receiving payments quarterly from a retainer client, annotate that. If you're billing monthly SaaS subscriptions to 20+ customers, document it that way.
A 12-month annotated bank statement often carries more weight than tax returns because it's contemporaneous, granular, and harder to misrepresent.
Document 3: Project Invoices & Client Contracts (Last 2 Years)
Compile a folder with:
- All invoices issued to clients over the past 2 years (sorted by client, then date)
- A one-page summary showing total invoiced amount per year and total collected
- Sample client contracts or engagement letters (redact confidential pricing; keep the terms and scope visible)
- If you have retainer clients: the current retainer agreement(s) with the monthly/quarterly fee amount clearly stated
The invoices + contracts package does two things: it shows that the income is legitimate client work (not personal transfers or loans), and it demonstrates a forward pipeline. If you're invoicing the same three retainer clients month after month, that's predictable income. If you've added new clients in the last 6 months, include a note saying so.
Document 4: The Irregular-Income Explanation Letter
Write a 1-page letter (not an essay) explaining your consulting income structure. Reference the specific documents above. The letter should address:
- Your consulting focus (e.g., "Strategic IT consulting for early-stage SaaS companies" or "Corporate tax advisory for mid-market Irish businesses")
- Why income is not monthly-uniform (e.g., "Work on 2–3 concurrent projects with fees paid upon project completion, typically 60–90 day payment terms. Retainer clients pay on 30-day invoicing.")
- Income stability and future outlook (e.g., "Current client roster: 3 retainer clients (€X/month each) + 2–3 project clients per year. No change in client mix anticipated.")
- A specific statement that all income is foreign-sourced consulting work, performed for foreign clients while you reside in Thailand
This letter is not negotiable. The BOI reviewers encounter thousands of applications; this one-page summary is how your income story gets communicated up the review chain. It buys credibility when your bank statements show 6-week gaps between major deposits.
Document 5: Thai Tax Registration (if applicable) + SSO Enrollment
This is optional but strengthens your application significantly. If you've been in Thailand for 12+ months and have Thai-source income (even a small amount), registering with Thai Revenue Department (even for non-filing, if you have no Thai-source income) demonstrates compliance awareness. For the LTR, it signals you're not hiding income or operating informally.
SSO enrollment (social security) is not required for the LTR Work-From-Thailand category, but it won't hurt. Some consultants operating as freelancers from Thailand choose to enroll in Thai social security as a good-faith gesture; others skip it because their foreign income doesn't qualify. Neither disqualifies you.
Common Consulting Income Documentation Failures
Irish consultants hit these snags repeatedly:
Failure: Lump-sum project payments without context. A bank statement shows a 50,000 EUR deposit, then nothing for 8 weeks, then another 50,000 EUR. Without the invoice and contract, the BOI reviewer can't tell if this is legitimate consulting work or a personal loan from a friend. Always attach the corresponding invoice number and client name (or client designation) to every major deposit. The 12-month annotated bank statement solves this completely.
Failure: Tax returns that don't match bank statements. Your 2024 tax return shows 60,000 EUR in net profit, but your 2024 bank statement shows 150,000 EUR in gross deposits. The discrepancy (business expenses, tax deductions) is completely normal, but the BOI gets suspicious. Always include a 1-paragraph explanation: "Gross invoiced income of EUR 150,000 in 2024 was reduced to net taxable profit of EUR 60,000 after subtracting business expenses including software licenses (EUR 12,000), professional services (EUR 8,000), and home office overhead (EUR 5,000). Full expense detail is available in tax filing." This sentence converts a red flag into a normal business operation.
Failure: Income from "consulting" that's actually something else. If your bank shows deposits from cryptocurrency trading, freelance copywriting through Upwork, or Amazon affiliate commissions, the BOI categorizes this as "gig income" or "passive income," not "sustained consulting business." If you're a true consultant plus you do side gigs, separate the documentation. Show your primary consulting work (the 80,000 USD threshold) and clearly label the side income as secondary.
Failure: Income in GBP or EUR without USD conversion clarity. Irish consultants typically invoice in EUR or charge GBP-based clients in GBP. The LTR threshold is USD 80,000/year. You must convert one 12-month period to USD and show you've cleared the bar. Use an average exchange rate for the relevant year or use actual spot-rate conversions for each deposit if they're all documented. Show the math explicitly: "2024 EUR 95,000 at average exchange rate of 1.10 EUR/USD = USD 104,500."
Failure: Missing proof that you're still earning.** The BOI approves based on past 2 years, but they're also assessing ongoing income. If you left your consulting practice 3 months ago, stopped invoicing clients, and are now living off savings, that's not income. Include a forward-looking statement: "As of March 2026, current retainer clients: [names], generating EUR 8,000/month ongoing. No departure from consulting expected." One sentence kills the "you used to consult but now you're retired" narrative.
Start your pre-screening to catch documentation gaps before submitting
Currency, Timing, and Bank Statement Rules for Consultants
The LTR requires the entire application to be documentarily consistent. That consistency is where consulting income gets tricky.
Bank statement dating and freshness. The BOI wants to see a bank statement dated within 30 days of your application submission. For consultants, this is normal practice. Pull it fresh when you're ready to submit. If the statement shows zero deposits in the 30 days before your application (because you're between projects), add a note explaining the project cycle.
Deposit recency and consistency. If your past 12-month bank statement shows deposits consistently, but the most recent deposit was 45 days ago with no activity since, the reviewer might question whether your consulting business is still active. Combat this by submitting your application soon after a client payment lands, not at the end of a project gap. Better yet, if your retainer clients pay on a fixed schedule, time your application for early in a billing month.
Currency and exchange rate disclosure. If all your consulting invoices are in EUR and your clients pay EUR, but your bank statement is in a multi-currency account showing both EUR and USD balances, make it explicit. Include a one-line annotation: "Bank statement converted from EUR and GBP deposits using month-average exchange rates for 2024–2025. Cumulative USD equivalent exceeds 80,000 USD annual threshold." This prevents the reviewer from assuming you're trying to hide currency arbitrage or misrepresenting income.
Loan vs. income: The critical distinction. If someone transferred 100,000 EUR into your account during the review period, the BOI needs proof that this was client payment (consulting revenue) and not a loan from a family member or investor. Every large deposit should have a corresponding invoice or contract. If a deposit is genuinely a loan (e.g., a business loan from a bank), label it as such and separate it from your consulting income calculation.
Health Insurance: The Compliance Gate
The LTR requires health insurance with a minimum of USD 50,000 inpatient coverage. This is non-negotiable; missing or non-compliant insurance kills your application.
What fails:
- Travel insurance (usually capped at USD 5,000–10,000)
- Thai-only local policies without international coverage
- Policies with USD 50,000 limit but high deductibles (e.g., USD 10,000) effectively reducing usable coverage
- Policies expiring before your visa approval date
- Policies from non-regulated providers or direct corporate self-insurance
What works:
- International expat health insurance from recognized providers (AIA, Allianz, Cigna, Aetna, etc.)
- Full policy documentation showing USD 50,000+ inpatient coverage
- Policy active for the entire LTR application period (at least 6 months coverage from application date)
- Certificate of Insurance issued by the provider (not a handwritten confirmation)
Get a quote 3 months before you submit your LTR application. Annual expat health insurance for a consultant in their 30s–40s runs USD 1,200–2,400/year depending on age and coverage level. This is a cost to budget, not a gotcha.
The Dependent Track: Spouse & Children Under 20
If you're bringing your Irish spouse or children to Thailand under your LTR, they can apply as LTR dependents. Requirements from the KB:
- Spouse or child under 20
- Health insurance (minimum USD 50,000 inpatient) OR Thai SSO enrollment OR USD 25,000 maintained in bank for 12 months (note: lower threshold than main applicant)
- Legal proof of relationship: marriage certificate (must be notarized by an Irish embassy/MFA official AND Thailand's MFA), birth certificate for children, adoption certificates if applicable
The marriage certificate requirement is specific: Irish certificates from the Civil Registration Office must be officially translated, then apostilled, then notarized by both the Irish Embassy in Bangkok and the Thai Ministry of Foreign Affairs. This is not a DIY process; budget 4–6 weeks and expect to work with a Thai legal translator. Most people underestimate the time here. Start the notarization process 3 months before your BOI application if possible.
Timeline Expectations for Irish Consultants
From initial application to final visa issuance: approximately 4 months.
- Weeks 1–4: Document gathering. This is the critical phase for consultants. You're assembling 2 years of tax returns, bank statements, invoices, contracts. If your documents are in Irish or EUR terms, you're also translating and converting to USD.
- Weeks 5–8: Pre-screening and BOI application. You submit to the Board of Investment. Processing time: approximately 2 months (the posted "6–8 weeks" is often closer to 8–10 in practice).
- Weeks 9–14: Visa issuance. After BOI approval, you move to Step 2: visa collection or e-visa processing. The government fee (50,000 THB / ~USD 1,400) becomes due at this stage.
- Weeks 15–16: Final visa stamp/confirmation in your passport.
Plan for 16 weeks minimum. If there are document clarification requests from the BOI (fairly common for consulting income), add 4–8 weeks.
Common Irish Consultant LTR Scenarios
Scenario 1: Sole Practitioner Consultant (Self-Employed)
Profile: You're a management consultant, strategic advisor, or business coach operating as a sole practitioner. You invoice 3–4 retainer clients per month (EUR 5,000–10,000 each) and take 1–2 project clients per year (EUR 15,000–25,000 per project). Annual gross income: EUR 80,000–120,000 (~USD 88,000–132,000).
Application strategy: Work-From-Thailand Professional track. Document your retainer contracts (showing monthly fees), your 2-year tax returns, and the 12-month annotated bank statement. The regular retainer deposits give the BOI a clear income picture. Write the one-page letter explaining how retainer income + project work gives you sustained 80,000+ USD/year. This is your cleanest path.
Key document: Current retainer agreements showing who pays what monthly. That single document accelerates approval.
Scenario 2: Company Director/Shareholder (Limited Company)
Profile: You operate an Irish Limited Company (Ltd) that provides consulting services. You draw a salary (EUR 40,000/year) plus dividends (EUR 40,000–60,000/year). Total personal income: EUR 80,000–100,000 (~USD 88,000–110,000).
Application strategy: Work-From-Thailand Professional track. The BOI accepts both salary and dividend income as legitimate personal income. Document:
- Personal tax returns (Form SA) showing salary + dividend income
- Company tax returns (Form CT1) showing the company's revenue and profitability
- Company bank statement showing regular revenue deposits
- Personal bank statement showing salary and dividend deposits into your personal account
The company financials are critical here. The BOI wants to see that the company itself is real, profitable, and earning the revenue that's funding your personal income. A company with 50,000 EUR in annual revenue paying out 80,000 EUR in dividends to you doesn't pass; the company's revenue must substantially exceed your personal take-home.
Key document: Audited or accountant-certified company accounts for the past 2 years. If your company is micro (fewer than 3 employees, under 250,000 EUR revenue), you may not be legally required to have audited accounts, but submitting them anyway signals transparency to the BOI.
Scenario 3: Consulting + Passive Income Mix
Profile: You earn EUR 50,000/year from consulting clients, plus EUR 30,000/year in passive income (dividend income from investments, rental property, or a digital product). Total: EUR 80,000 (~USD 88,000).
Application strategy: Highly Skilled Professional track if you can tie your consulting to a BOI target sector (digital, biotech, etc.), otherwise Work-From-Thailand. Document both income streams separately, then show the combined total. The passive income must be documented with 2-year history (dividend statements from your broker, rental lease + bank statements, or product revenue reports from your platform).
Key document: A spreadsheet showing consulting income + passive income by month/year, with total exceeding 80,000 USD annually. The BOI will ask for source documentation on each stream separately, so prepare both.
FAQ: Irish Consultants & LTR Visa
Can I use project invoices from one-off clients as proof of "sustained" income?
Yes, if you have a 2-year pattern of ongoing projects from multiple clients. A single 50,000 EUR project doesn't count as sustained income. A history of 3–4 projects per year from 2–3 distinct clients, over 2 years, does. The BOI is looking for income continuity, not individual transaction size.
What if my consulting income was irregular — high in 2024, lower in 2025?
You'll need to address the decline explicitly. Include a 2-3 sentence explanation in your application: why the 2025 slowdown (market contraction, voluntary sabbatical, portfolio transition) and what evidence you have of recovery in 2026 (new client signed, increased retainer rates, project pipeline). If you can't credibly explain the decline, your approved income threshold might be assessed at the lower year, not the higher one.
Does the LTR require me to maintain the consulting income after approval?
No. The LTR approval is based on your past 2-year income history. After approval, there is no ongoing income monitoring. You could stop consulting entirely and live on savings. However, the annual address reporting requirement means Thai immigration knows where you live; leaving yourself in a visible income vacuum is not operationally wise if you want to maintain long-term legal standing. The practical answer: maintain some level of consulting income or establish other verifiable funds (savings, pension, investments).
Can I use Stripe or PayPal statements as proof of consulting income?
Yes, if the statements clearly show client payments deposited to your bank account. Stripe and PayPal settlement reports are good supporting evidence, but the primary document should always be your bank statement showing the actual cash received. The BOI wants to trace the money through your banking system, not just a payment processor report.
Do I need to close my Irish business or stop invoicing clients once I get the LTR?
No. The LTR allows you to continue consulting work for foreign clients while living in Thailand. There's no requirement to wind down your business. However, once you're tax-resident in Thailand (typically after 180 days), you become subject to Thai personal income tax. Consult a Thai tax accountant and an Irish tax advisor before moving to ensure you're compliant with both jurisdictions.
What if my consulting clients are mostly Irish or UK-based, but I'm working from Thailand?
That's fine. The LTR doesn't require you to work for multinational corporations or global companies. Consulting for Irish/UK clients while based in Thailand is a standard arrangement. The BOI reviews the work arrangements, not the client location. Verify that the consulting contracts don't prohibit remote work from outside your home country; some contracts have geographic restrictions.
Issa's Consulting Income Pre-Screening for LTR
The difference between an approved and rejected LTR application for a consultant often comes down to documentation sequencing and framing. Consultants are used to client-facing communication; they're not accustomed to bureaucratic documentation standards. Small gaps — missing one year of tax returns, invoices not labeled by client, no connection drawn between deposit and project — get flagged by the BOI and slow approval.
Issa's pre-screening process for consultants includes:
- Verification that your 2-year income averages above USD 80,000/year (or qualifies under the master's degree exception)
- Audit of your bank statements to confirm deposits match invoiced consulting work
- Review of your tax returns to confirm no red flags (unexplained income, deduction inconsistencies, multi-year losses)
- Health insurance verification against BOI requirements (often the first point of rejection)
- Documentation assembly guidance specific to consulting income: which invoices to include, how to annotate bank statements, what client contracts to submit
If your income is below 80,000 USD but you hold a master's degree in a relevant field, we verify that qualification. If your consulting income is mixed with other income streams, we separate and document each. If you don't meet the LTR thresholds, we tell you directly and explain your alternatives (DTV Visa for continued short-term stays, or Non-O Retirement if you're 50+).
Our 100% money-back guarantee covers eligible consulting LTR applications: if your application is rejected due to documentation errors on Issa's side, we refund both our service fee and your BOI government fees (50,000 THB). That financial backing exists specifically because we've seen how much rework a botched consulting income application takes.
Irish consultants tend to be decisive and results-driven. The LTR application requires patience and documentation precision. Get the pre-screening right, and the approval follows. Apply via the Issa Compass app and let our team assess your consulting LTR eligibility before you commit your time and government fees.
