Resolve the uncertainty before it grows. Late filings and unpaid balances can create surcharge and penalty exposure. The applicable amounts depend on the return, tax due, delay and any relief. We distinguish estimates from confirmed balances.

Before the meeting
Bring what you have
Copies or photos can help us start. We will identify what is still missing.
Supporting information
- Recent bank statements and available accounting records.
- Letters from the Revenue Department, DBD, Social Security or BOI.
- Your BOI certificate and reporting records, if promoted.
Make room for year-end preparation
If your financial year ends on 31 December, use the months before closing to locate missing records, reconcile balances and agree the audit timetable. Companies with another year-end should plan around their own accounting period.

Your questions answered
Before you book
The initial review has a defined scope, with no ongoing commitment.
What does the THB 2,500 cover?
A 30-minute review of your company’s filing status based on the records made available, covering Revenue Department, DBD and Social Security items, plus BOI reporting if promoted. You receive a written one-page summary within 3 working days of the review, subject to receipt of the required records.
Do I have to hire UnionSPACE afterwards?
No. The summary is yours to keep. If you would like us to resolve the issues identified, we provide a separate fixed-price Catch-up Package quotation for your approval.
We are a BOI-promoted company. Is that covered?
Yes. The review can cover your BOI reporting position and whether BOI and non-BOI activities are separately tracked in the records provided. The initial health check is not a full BOI audit or a certification that all promotion conditions have been met.
What if my records are incomplete?
Bring what you have: filing receipts, bank statements, company records and any official letters. Photos or copies can help start the review. We identify missing information and distinguish items we can verify from those requiring further records.
Which languages do you work in?
English, Chinese, Russian, Burmese and Thai.
Is this an audit or a government clearance?
No. It is an initial filing-status review, not an audit opinion, formal tax advice or government clearance. The summary is based on the information reviewed, and any estimated liabilities remain subject to confirmation.

A focused review with a clear scope
The health check is an initial review of filing status, not formal tax advice or an audit opinion. Any estimated amounts depend on the records made available and may need further verification. Catch-up filings, accounting reconstruction, audit work, official taxes, surcharges and fines are separate from the health check fee unless expressly agreed.
UnionSPACE is an independent private service provider, not a government authority. Official filing channels remain available directly through the relevant agencies.
