General Taxation Framework and Tax Administration
What the exam tests
This domain covers the legal architecture of Mongolian taxation and the procedural rules that apply across all taxes: registration, assessment, payment, collection, rights and obligations.
Hierarchy of tax legislation
- The Constitution is the foundation.
- The Law on Taxation (2019) is the general procedural law.
- Specific tax laws (CIT, PIT, VAT, excise, etc.) control their own tax bases and rates.
- Government resolutions and ministerial orders implement the laws but cannot contradict them.
- Ratified international treaties generally prevail over domestic tax law.
Registration and TIN
Taxpayers must register before starting activity and obtain a taxpayer identification number. Changes in address, activity or bank details must be notified within 10 days; deregistration follows cessation.
Assessment and collection
Mongolia uses self-assessment, with the tax authority checking returns and issuing assessments. Collection tools include offsets, penalties, late-payment interest, bank-account freezes and seizure.
Rights and obligations
Taxpayers may receive information, be represented, keep confidentiality and appeal. They must register, keep records for at least 5 years, file returns and pay on time.
Worked example
A company files a VAT return showing MNT 1,000,000 due on the 10th but pays on the 20th. The principal is 1,000,000; a 20% penalty on the unpaid tax is 200,000, plus late-payment interest. If the company disputes the assessment, it must appeal within 30 days of receipt.
Traps
Confusing state and local taxes; assuming a ministerial order overrides a tax law; missing the appeal deadline; and treating a penalty as tax-deductible.
