The better practice, when negotiating a physician employment agreement, would be to NOT automatically assume, in laying out the effect of termination, that termination without cause means the employee is without fault. Instead, the employer would be better served in taking a more hard-line approach. For example:
If you are single and under age 65, you can earn up to $9,499 in a year and not file a tax return. Should you be 65 or older, you could earn up to $10,949 and be exempt from filing a federal tax return. However, you may qualify for an Earned Income Tax Credit, which is refundable in cash to you. Also, if you've had income taxes withheld, you should file to receive a refund of your money. Married Taxpayers Filing Jointly If both married taxpayers are under 65, they can earn up to $18,999 and not need to file a return.
You can't claim an exemption for yourself if you're a dependent, so you're limited to the amount of the standard deduction. You must file a return and pay taxes on income that exceeds $6,200 in 2014 and $6,300 for the 2015 tax year. This rule only addresses earned income, however.
