Built for growth,
shaped by decades.
PTNP Accounting was founded with a single mission: give businesses in Thailand access to reliable, professional accounting they can trust. From our first clients in the 1980s to the growing companies we serve today, that mission has expanded — from compliance alone to active tax planning.
"We have helped businesses in Thailand through every economic cycle for over four decades. Accuracy keeps you compliant. Good advice keeps you profitable."

Our core values
These are the principles that guide how we work with our clients — we make sure we are client-oriented while respecting compliance, so you can grow sustainably.
Maximize your benefits
We check every figure before a report or filing goes out, and advise on the deductions and allowances you are entitled to under Thai law. Filing on time keeps you clear of the 1.5% per month late surcharge.
Promote compliance
Thai tax law changes every year. We stay current on every amendment, so your business always operates within the law — and pays only what it owes.
Ensure transparency
You always know the state of your finances. We speak with truth, show our work on PEAK, and explain every filing before we submit it.
Connect you for more
We support you beyond accounting with our network of professionals across various industries. You are more than just our client — we want you to grow at your maximum and beyond.
