With the addition of two banks, the total number of banks in Azerbaijan that are registered with the IRS now sits at 42 out of 44, the U.S.-Azerbaijan Chamber of Commerce said on Tuesday.

The agreement between both nations, which allows U.S. tax authorities to gain access to account information from Azerbaijan accounts that belong to U.S. citizens, should be fully implemented in the second half of 2015. This comes as part of an international effort on the part of the IRS to track and be able to legally acquire delinquent taxes from foreign bank accounts that are held by Americans.

Bank subsidiaries in Georgia also have been added to the register, including Caucasus Development Bank-Georgia and the Georgian branches of the International Bank of Azerbaijan and PASHA Bank.

Because the banks willingly registered with the IRS, Azerbaijan is listed as a cooperative country.

As of July 2014, banks in all countries who are part of this agreement are expected to connect to the IRS system and inform the agency about delinquent accounts when asked to do so.
