Mongolia Rental Income Guide 2026

Overview — Rental Income Tax in Mongolia

Rental income from letting or leasing of immovable property (land and buildings) is chargeable to income tax in Mongolia. For individuals, the net rental income (after allowable deductions) is included in total income and taxed at the flat 10% IIT rate. For companies, rental income is included in chargeable profits and taxed at the applicable CIT rate (25% standard, 10% small business). The tenant may be required to withhold tax at source on rent payments to non-resident landlords. Property owners must ensure compliance with MTA registration and reporting requirements.

Individual Landlords — 10% Flat IIT

For individual landlords, rental income is added to other income and taxed at the flat 10% IIT rate. The taxable amount is net rental income (gross rent minus allowable deductions). If the landlord does not claim deductions, the MTA may apply a standard deduction of 30-40% of gross rent (deemed expense ratio). Landlords who file an annual return and claim actual expenses may benefit if their actual expenses exceed the standard deduction. The tax-free threshold of approximately MNT 4,800,000 per year applies to total income including rent.

Allowable Deductions

Landlords may deduct the following expenses from gross rental income when calculating net taxable rental income:

• Repairs & maintenance — not capital improvements
• Property management fees — paid to licensed agents
• Insurance premiums — building and fire insurance
• Mortgage interest — interest on loans used to acquire or improve the property
• Property tax — annual property tax paid to MTA
• Land use fees — annual fees paid to local government
• Agency & legal fees — for tenant acquisition and lease agreements
• Utilities — if paid by the landlord (water, electricity, heating)

To claim deductions, the landlord must maintain proper records and receipts. The standard deduction (30-40% of gross rent) is available as an alternative to itemised deductions.

Corporate Landlords — 25% CIT

For companies earning rental income, the net rental profit is included in the company's chargeable income and taxed at 25% (standard) or 10% (small business). Companies may claim full deductions for all expenses incurred in earning the rental income, including depreciation (capital allowances) on the building. Corporate landlords must file annual CIT returns by 15 February. Rental income from leasing commercial property is a common business activity in Ulaanbaatar and other urban centres.

Vacant Property Rules

Rental income is only taxable when the property is actually let. There is no deemed rental income for vacant or owner-occupied properties. However, property tax and land use fees continue to apply regardless of occupancy. If a property is let for only part of the year, the rental income for that period is subject to tax. Expenses incurred during vacant periods (e.g., security, maintenance) may be deducted. Short-term letting (e.g., Airbnb, holiday rentals) is also subject to rental income tax at the standard rates.

FAQs

Who is responsible for withholding tax on rent?

For payments to non-resident landlords, the tenant must withhold 10% (individual) or 20% (company) and remit it to MTA. For resident landlords, there is generally no withholding obligation on residential rent.

What if I rent my property through an agency?

The agency may be designated as the withholding agent. The agency must remit the appropriate tax and issue a withholding tax certificate to the landlord.

Are advance rent payments (e.g., 1 year upfront) taxable in one year?

Yes, rental income is taxable in the year it is received, regardless of the period it covers. If you receive 1 year's rent in advance, the full amount is taxable in that year.
