=== International tax considerations ===
Typically mutual funds supply the correct tax reporting documents for only one country, which can cause tax problems for shareholders citizen to or resident of another country, either now or in the future.

==== Implications for US investors ====
US citizens/taxpayers living at home or abroad should particularly consider whether their investment in an ex-US fund (meaning the fund is administered by a foreign investment company) not providing annual 1099 forms (which report distributed income and capital gains/losses) or annual PFIC annual information statements will be subject to punitive US taxation under section 1291 of the US tax code. Note that if a PFIC annual information statement is provided, a careful filing of form 8621 is required to avoid punitive US taxation.<ref>{{cite journal
