Yes there are two that you should take note of:
- You are now required to report payments to all individuals and businesses over $600 during the calendar year on Form 1099 (previously required only for non-corporate).
- Starting in 2013, employers will be required to withhold an additional .9% of Medicare tax on employee wages in excess of $200,000. And certain individuals will owe a 3.8 % unearned income Medicare contribution tax on net investment income.
