On the form it says to do the w4 multiple jobs thing on the w4 for highest paying job only. What do I do if the highest paying job requires a 1099? How do you enter that into the calculator?
Don't use the instructions and worksheets on the form. Use the Tax Withholding Estimator on the IRS web site. It will tell you what to put on your W-4 forms. (The first page of the W-4 form is all that you give to your employer.) The Tax Withholding Estimator has a place to enter self-employment income.
You can cover your tax for the year with a combination of withholding and quarterly estimated tax payments. Since the self-employment is your largest source of income, you might prefer to make estimated tax payments instead of trying to have enough tax withheld from your W-2 jobs to cover the self-employment income. VolvoGirl has given you more details about making estimated tax payments. In the Tax Withholding Estimator, under Other Sources of Income and Tax Payment, you can enter your self-employment income and the amount of estimated tax that you have paid or plan to pay.
