  • Project planning and documentation strategy
  • Complete preparation and submission of the BOI application

Government, Visa & Compliance Costs

Company Registration & BOI Visa Fees

When registering a company for BOI approval in Thailand for 2025, government fees are determined by registered capital:

Obtaining BOI-specific work permits and visas requires budgeting for:

  • Work permit fees: THB 750 to 3,000 depending on the permit period
  • Visa processing: approximately THB 25,000 plus digital work permit (THB 3,000) and visa extension (THB 1,900)

These charges are payable at different stages, such as at registration, visa issuance and during renewals.

Annual Compliance Costs to Budget For

After registration, annual compliance expenses are critical for maintaining BOI status:

  • Accounting services: THB 50,000 to 150,000 per year
  • Annual legal compliance reviews and reporting
  • Regular statutory filings to Thai authorities

Budgeting for these recurring costs and setting clear calendar reminders helps avoid lapses that could put your investment promotion at risk.

By planning for both upfront registration expenses and recurring compliance costs, companies can operate with confidence, avoid penalties and fully leverage BOI incentives.

Hidden & Additional BOI Expenses

If your business undergoes significant project updates or if the application is challenged, extra fees for legal advice and document revision may apply.

How to Plan for Unexpected BOI Expenses

Track potential add-ons from day one with a checklist that covers:

  1. Translation, notarization, and legalization requirements
  2. Application amendment fees and expected timeframes
  3. Reserved funds for legal support and urgent requests

Build a financial buffer of 10%-20% above quoted fees for hidden charges or urgent needs.

Proactive communication with consultants is essential, ensuring transparency about scope, timelines, and all potential out-of-scope charges.

How to Cut BOI Application Costs

Ways to Reduce Professional & Admin Fees

Begin by preparing all required BOI documents early, which can significantly reduce your reliance on external consultants and speed up approvals.

Consider these immediate cost-saving steps:

  • Create checklists to ensure documents are complete before consultant review
  • Batch multiple applications or company services together to receive volume pricing
  • Use certified digital signature and filing systems to lower administrative time and courier costs
  • Negotiate consultant rates by clearly outlining your project’s scope and deliverables
  • Assign qualified in-house staff to manage basic compliance tasks, limiting external billable hours

Smart preparation is the first tool for keeping BOI application costs under control.

Long-Term Savings with Smart BOI Planning

Investing in structured, high-quality initial preparation reduces the chance of costly amendments or reapplication.

Collaborating with experienced BOI consultants can result in:

  • Streamlined approvals and reduced processing time (from six months to as little as three months)
  • Fewer government queries or document resubmissions, which minimizes legal review costs
  • Guidance on ongoing compliance, helping you avoid unexpected penalties

Prioritizing early planning, transparent negotiations, and high-quality consultant partnerships not only cuts upfront costs but also delivers smoother approvals and lower compliance expenses over time.
