re: Employee Payroll Tax Withholdings-Question

Why not prepare a projected tax return for 2013, and determine what your tax liability is likely to be? It's not that hard. You know what your salary will be, and you can add whatever amount of income you anticipate from the rental activity plus any other sources of income. Then you take into account any adjustments to income, such as IRA contributions or student loan interest, to determine your projected AGI. For your deductions you can play it safe and use the standard deduction, or you can estimate the amount of itemized deductions you will be able to claim. The final step to determining your projected taxable income is to subtract the amount of personal exemption(s) you are entitled to. From this you can get your projected tax liability from the tax tables or tax rate schedules. Compare the projected liability to your expected withholding and any tax credits to determine whether you will owe money or not. Adjust your withholding accordingly.

You can do the same for 2014 as soon as the IRS announces adjustments to items for inflation. There may be some complications due to Obamacare, but they shouldn't apply if you have an employer sponsored health insurance plan.
