Montenegro began sharing 12 years of FATCA data with the IRS Sept. 30

Montenegro transmitted 12 years of financial account records to the US Internal Revenue Service on Sept. 30, operationalizing its data-sharing pact under the Foreign Account Tax Compliance Act.

Operationalizing an eight-year-old treaty

The transmission marks the first live data transfer from the Montenegrin Tax Administration to the IRS through the secure International Data Exchange Service, covering annual tax data from 2014 through 2025, the tax authority announced. While the exchange is a major technical milestone, it represents the enforcement of an existing framework rather than a new levy on foreign residents.

Montenegro signed its intergovernmental agreement with the United States on June 1, 2017 and the pact formally took effect on March 28, 2018, after parliamentary ratification. Local banks and investment firms gathered data for years under domestic reporting guidelines, but technical hurdles delayed the government-to-government pipeline until the rollout of new submission software this fall, the agency reported.

Account thresholds and treaty exemptions

The automatic reporting rules target US citizens, permanent residents and foreign companies controlled by US taxpayers holding assets in Montenegrin banks. However, the underlying treaty carves out several balances and low-risk financial vehicles:

• New individual deposit accounts maintained by US persons fall outside annual review if the balance stays at or below $50,000 at the end of the calendar year.

• Pre-existing entity accounts opened before June 30, 2014, with balances under $250,000 were exempt from initial review until values exceeded $1 million.

• Pre-existing cash-value insurance policies and annuities with balances below $250,000 require no institutional reporting.

• Qualified pension funds, government escrow accounts, term-life policies and certain registered retirement plans receive full treaty exemptions.

Nomads who opened accounts while moving to Montenegro don't trigger reporting automatically if their deposit balances stay under the $50,000 threshold, according to treaty terms.

Transmitted records and bank obligations

For accounts that exceeded the treaty thresholds, Montenegrin financial institutions supplied names, residential addresses, US taxpayer identification numbers, account balances, gross interest and dividend payouts. Custodial accounts also included gross proceeds generated from sales or redemptions of financial assets, state broadcaster RTCG reported.

Montenegrin banks must gather this data annually and submit it to the Tax Administration by June 30 of each year, following domestic administrative rules. The tax authority then compiles the files for transmission to the US through the IRS portal. The official release did not state the total number of taxpayers or individual accounts included in the initial batch, nor did it disclose whether the IRS has completed processing the multi-year dataset.

Compliance checks for American nomads

The government-level transmission doesn't create a new tax or impose direct filing fees on individual depositors. Still, US remote workers and long-term expats holding Montenegrin accounts must ensure their personal IRS disclosures match local bank reports, since closing an account during the year still triggers reporting for the final balance before closure.

US taxpayers with foreign balances exceeding $10,000 at any point in the calendar year must file a Foreign Bank and Financial Accounts Report, while higher thresholds require IRS Form 8938. Non-US expats who provided a US phone number or address to Montenegrin banks may also receive requests from local compliance desks to submit self-certification forms confirming non-US tax status.

Montenegro is also developing software to adopt the OECD Common Reporting Standard, though officials haven't set a start date for multilateral exchanges with other foreign tax agencies.
