Tax & business registration is a Taiwan market dataset sourced from MOEA, served by TW Market Data as GET /v2/datasets/tax-business-registration.

Overview

tax-business-registration is a reference dataset: one active record per registered business resolving an identifier to its public registration basics, sourced from the MOEA via data.gov.tw. It is public business-registration reference only — the registered name, status and capital that the MOEA publishes openly — not private tax-filing or confidential tax data. Each row carries a source role and lineage so a field can be reconciled against the open dataset.

Field	Type	Description
`company_id`	string
`business_registration_number`	string
`tax_id`	string
`company_name`	string	Registered company name.
`registered_address`	string

Provenance

These columns are returned alongside the data and record where the row came from. They are provenance, not the dataset's subject matter, so they are listed here rather than in the field table.

Getting started

Put your key in the X-API-Key header.
Add query parameters (symbol, date range, limit).
Send the request and read the data array.

  -H "X-API-Key: sk_live_..."

Filtering

`limit`	No	integer	Maximum rows to return.

Python

import requests

resp = requests.get(
    "https://api.twmarketdata.com/v2/datasets/tax-business-registration",
    params={"source_as_of_date": "2026-04-30"},
    headers={"X-API-Key": "sk_live_..."},

print(resp.json()["data"])

OpenAPI

This endpoint is GET /v2/datasets/tax-business-registration. The full machine-readable schema (parameters, security, response envelope) lives in the OpenAPI spec.

Notes & limitations

Public business-registration reference only: it exposes what the MOEA publishes openly (registered name, status, capital), not private tax filings or any confidential tax data.
The example business_id is masked (########); a real query returns the actual 8-digit MOEA unified business number from the open dataset.
