Frequently Asked Questions

US Tax

1) Late Filing of Tax Return

In September 2012, the IRS published “simplified procedures” for Americans who haven’t filed their taxes for years.

The plan allows taxpayers to file tax returns for the last three years, as well as foreign bank account records for the last six years. If they meet certain requirements, they will also submit a two-page questionnaire to the Treasury.

It depends on your circumstances. Some people cannot participate in the simplified program. The IRS requires taxpayers to file all undeclared tax returns.

For more information, please contact our tax experts.
