I have a taxes question that google is failing to answer for me.
If I teach private guitar lessons as a side income, what percent will be taxed?
Let's say I make $1000/month.
Does that just add on to my total yearly income, or is it taxed separately?
I don't know douchebag, maybe you should ask a tax attorney.
It would be Self Employment Income and you are supposed to pay quarterly taxes. The percentage you would be taxed would depend on the amount you actually make and the number of employees you have. If you have employees you must pay FUTA (unemployment/payroll) and FICA (Income, Medicare, Social Security). Since you wouldn't have employees, you would only pay FICA. The IRS asks that you use last years numbers to determine your quarterly payments...but if you do not have numbers from the prior tax year, one must estimate using the tax brackets and corresponding percentages. Income percentages = Brackets and Medicare/Social Security = Set percentages. I would recommend not using estimates and just applying the proper percentages to the actual numbers you make quarterly.
Some people might add it to their income at the end of the year, but it would be characterized by the IRS as self employment.
