Penalties also exist for the Employer if the payroll withholding is not recorded in a timely fashion and paid-in to the tax authorities.

18. Seite: 18 Special Topics—Social Security ► U.S. system—maximum amount assessed but no maximum for the 1.45% medicare portion (e.g. Unlimited medicare tax on worldwide compensation subject to the rules). Other elements: ► Totalization Agreement between Germany and the U.S. ► Certificate of Coverage to maintain coverage in „home country“ ► Avoidance of double coverage/taxation ► Does not cover U.S. Federal Unemployment Tax (FUTA) or State equivalent (SUTA).

19. Seite: 19 Special Topics: IRC §401(k) ► A U.S. qualified pre-tax plan at the employer level which provides for a reduction of U.S. (and State) taxable compensation for the employee. Issues: ► Allows an employee to reduce his/her taxable compensation on a yearly basis. Example: Gross compensation of $100,000 and amount contributed to the 401(k) is $15,000. Taxable compensation is $85,000. ► Restrictions as to when the employee or former employee is allowed to withdraw $ from the 401(k) plan. ► Taxation issues when the employee returns to home country and eventually withdraws the amount. ► Income tax treaty issues (Article 18: Pensions).
