Flash Alert 2018-026

This GMS Flash Alert highlights recent tax and social security changes in Mongolia that have been approved by the country’s parliament and represent a reversal, in some cases, of previous decisions made. 


The changes and reversals, which we discuss further below, have created some confusion and uncertainty for individual taxpayers and their employers.  Affected parties should consult with their qualified tax professionals before taking any decisions.

In cases of assignments to Mongolia where assignees are subject to Mongolian taxation, and for assignees working outside Mongolia but still subject to Mongolian taxation, international assignment cost projections and budgeting should reflect the changes described in this newsletter once they come into effect.  Where appropriate, adjustments to gross-up packages and withholding taxes need to be considered.

Personal Income Tax (PIT)

The PIT rate on employment income for resident taxpayers (i.e., those who stay more than 183 days in Mongolia in the tax year) will revert back to a flat 10-percent rate, reversing the previously-approved marginal tax rates of 15 percent, 20 percent, and 25 percent, which represented an effort to make the tax system more progressive and boost yields to the country’s treasury.  (For prior coverage of earlier moves to amend the country’s tax system, see GMS Flash Alert 2017-077, 26 April 2017.)

The tax rate on Mongolian-sourced income (including fringe benefits, property income, dividends, business income, and interest income) for nonresidents will remain at the newly-introduced flat 20-percent tax rate.  Prior to 1 January 2018, the same income tax rate had been applicable to both resident and nonresident taxpayers.

The annual PIT credit of MNT 120,000 has also been revised as shown below – this also represents a reversal of the higher credit that had previously been agreed.  For monthly payroll purposes, we illustrate this on a monthly basis.  Based on the newly approved law1, where income is above MNT 36 million per annum (approx. USD 14,000), there will no longer be a PIT credit available.

Monthly taxable employment income (MNT)
2017 credit 2018 credit previous change
2018 credit new change
2019 onwards
Up to 500,000 7,000 10,000 13,333 20,000

1,500,001 – 2,000,000 7,000 10,000 8,333 15,000
2,000,001 – 2,500,000 7,000 10,000 6,667 13,333
2,500,001 – 3,000,000 7,000 10,000 5,000 11,667
Over 3,000,000 7,000 10,000

Further details on the mechanism for the refund / credit in relation to any overpaid PIT from January payroll have not yet been made available by the tax authorities.

Social Health Insurance and Retirement Age

The Social Health Insurance rate increases will be incremental over the next three years.2  The increased rates which are applicable from 1 January 2018, are as below:

Contribution 2017 rate New rate 2018
Employee 10% (capped) 11% (capped -- current cap of MNT 264,000 per month)
Employer 11%-13% (depends on industry) 12%-14% (depends on industry)
