Thai limited companies must file monthly: VAT returns (PP.30, due by the 15th), withholding tax (PND.3 and PND.53, due by the 7th), and Social Security contributions. Annually, you must file corporate income tax returns (PND.50, within 150 days of year-end) and submit audited financial statements to the DBD (within 5 months of year-end). Simple Outsource manages every one of these filings — you don’t need to track the deadlines yourself.

A bookkeeper records transactions and keeps your ledger up to date. An accountant — or a full accounting service — goes further: preparing financial statements, managing tax positions, handling Revenue Department filings, and ensuring your business is audit-ready. Many Thai SMEs use bookkeepers and assume compliance is covered. It often isn’t. Simple Outsource provides a complete accounting service, not just data entry.

Yes. Accounting services can be engaged independently — you don’t need to outsource any other function to get started. Many clients begin with monthly accounting and add company registration support or EOR as they grow. We scope every engagement around what you actually need right now.

Late filings trigger penalty surcharges — typically 1.5% per month on the unpaid tax amount, plus fixed penalties depending on the filing type. The Revenue Department can also initiate an audit if filings are consistently late or incomplete. Simple Outsource monitors all filing deadlines and submits on your behalf — proactively, every month, without you needing to prompt us.

Yes — Thai accounting compliance applies from the first month of operation, regardless of company size or revenue. A small company with few transactions still needs to file VAT returns, withhold tax correctly, and submit annual accounts to the DBD. Simple Outsource works with businesses of all sizes, and our fees are scaled to your transaction volume — so a small company pays a small company rate.

A Thai limited company registration involves: choosing the right entity structure, preparing and filing with the Department of Business Development (DBD), registering for tax and VAT, and opening a corporate bank account. Each step has its own documentation requirements and timeline. Simple Outsource manages the full process — from structure advice to first day of operations — with no steps left for you to figure out on your own.

We manage the full transition. Simple Outsource contacts your previous provider for the accounting handover package — ledgers, reconciliation records, filing history — reviews for any gaps or errors, and reconciles the books before taking over the monthly cycle. Most transitions complete within two to four weeks. You don’t need to manage the migration process.

Simple Outsource charges a fixed monthly fee based on your transaction volume — with VAT, withholding tax, and annual filings included in the standard service. We don’t apply generic packages. Book a free consultation and we’ll give you a clear, itemised quote based on your actual business size and transaction volume.
