Accounting firms in Chiang Mai: what they charge, and where you file

Who is actually in this market

Chiang Mai has a real supply of accounting offices, and most of them are small Thai practices in Hang Dong, San Kamphaeng, Doi Saket and Mae Rim rather than in the old city. They publish their rates openly, in Thai, in tables banded by document count or by monthly revenue. A handful of Bangkok firms also run Chiang Mai landing pages and compete here remotely, which is worth knowing when a website looks local and the office is not.

The visible spread is wide and it is real. Monthly bookkeeping starts at 1,000 baht at one family office and 1,500 to 2,000 baht at several others, against 4,500 to 12,000 baht at the larger local practices. Registration of a limited company runs 9,500 to 12,000 baht, and one firm publishes 6,000 baht with the government fee explicitly inside it.

What a website says and what a firm charges

A caution that came out of building this page. We wrote to the Chiang Mai firms we had quoted, telling them they were on it and inviting corrections. One of them, IC Accounting, replied the same day with what it called ราคาที่แท้จริง, its real pricing, and it was not what its website said.

The published ladder was banded by document count and started at 2,500 baht. The current quotation is banded by annual revenue, starts at 4,500 baht a month for filings alone, and runs to 12,000 for full outsourced accounting. Those figures are marked on the table below as sent by the firm rather than read from its site.

Take the general point rather than the specific one. A published rate card is a starting position and can be a year out of date. It tells you whether a quote you have been given is roughly normal. It does not tell you what that firm will charge you this week, and only a quote does that.

The catch, and it is a real one

Of the Chiang Mai firms publishing these prices, exactly one states plainly that it serves foreign nationals with English language support. The rest have no English page and say nothing about foreign clients. That does not mean they will refuse you, and several serve clients across the country online. It does mean the cheapest quotes in this city are, in practice, in a language most of the people who need them cannot read.

Visas are the exception, and the silence is the finding

On the accounting side Chiang Mai is unusually transparent. On visas it is the opposite. We checked every expat facing visa agency we could find in the city and almost none publishes a service fee anywhere on its site. Two of the exceptions are instructive: one splits its own 3,000 to 7,000 baht fee cleanly from the 10,000 baht government DTV fee, and another publishes a single band of 18,000 to 69,000 baht with no split at all.

If you are being quoted verbally for visa work in Chiang Mai, the published Bangkok figures on the visa and work permit page are a reasonable sanity check, because there is nothing local to check against.

Where you actually file

This is the part nobody writes down, and it costs people a wasted morning. Your company registers in one building, your tax is filed to another, your work permit is issued at a third, and your visa extension happens at a fourth several kilometres away beside the airport. The offices below were each checked against the agency’s own page, and two of them contradict advice that is still widely repeated in English.

What Chiang Mai firms publish

Each figure came from the firm itself, in most cases printed on its own website. Where a firm has sent us its current rate card instead, the row says so. Follow the link, or tell us if something has changed and we will correct it.

The offices, and which is which

Each of these was checked against the agency’s own page on 29 August 2026. Where the official source contradicts advice that is still repeated in English, we say so rather than quietly agreeing with it.

The national picture

Chiang Mai prices sit inside a wider market. Each of these compares what firms across Thailand publish for one service, with the source on every figure.

• Monthly bookkeeping & tax filing: 1,000 to 20,500 a month
• Annual audit: 4,000 to 50,000 a year
• Company registration: 2,000 to 70,000 service fee, plus about 6,350 in government fees
• Visa & work permit: 7,900 to 40,000 per person
• BOI promotion: 180,000 to 320,000 one off
• LTR & SMART visas: 22,000 to 100,000 service fee, plus 50,000 government
• Payroll & social security: 160 to 650 a head, or 500 to 8,000 flat a month

Published prices move and government offices relocate. This is a guide to what is printed, not a quote, and not accounting, legal or immigration advice. Found something that has changed? Tell us and we will fix it.
