Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Thuế TNCN Việt Nam — kỳ tính thuế 2026

Data cập nhật: **22/10/2026** (v2.6.4). Số phiên bản máy đọc: `version.json`. Mọi con số trong `references/` đã đối chiếu toàn văn Công báo trừ chỗ ghi **TC** (nguồn thứ cấp).

> Thông tin chỉ để tham khảo, không thay thế tư vấn thuế chuyên nghiệp. Mọi câu trả lời phải kèm điều khoản và ngày cập nhật data.

## Quy tắc nguồn (bắt buộc, không có ngoại lệ)

Khi kiểm tra, đối chiếu hay cập nhật văn bản pháp luật, **chỉ dùng nguồn chính chủ**: `vbpl.vn` (CSDL quốc gia về VBQPPL, Bộ Tư pháp), `congbao.chinhphu.vn`, `vanban.chinhphu.vn`, `xaydungchinhsach.chinhphu.vn` (Văn phòng Chính phủ), `vbpq.mof.gov.vn` (Bộ Tài chính), `gdt.gov.vn` và `portal.mof.gov.vn/hoidapcstc` (Cục Thuế, Bộ Tài chính), `quochoi.vn`. Web search phải giới hạn bằng `site:` vào các tên miền này.

**Cấm** lấy kết luận từ thuvienphapluat.vn, luatvietnam.vn, luatminhkhue, các trang "hỏi đáp pháp luật", blog kế toán, báo, mạng xã hội, video. Lý do, phải nhớ:
- Các trang đó làm SEO để kiếm tiền: mỗi bài là văn bản gốc **cộng thêm nhận định của người viết**. Model đọc vào rất dễ lấy luôn nhận định đó làm câu trả lời, tưởng là luật.

How to install

The exact contents, by fingerprint
mdr add tndvnn/tncn/tncn@sha256:c85292595e9ea49d

The line at the top of this page pins the label git:20261022.3ff4753, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
