Sole Proprietorship

I am looking to start a sole proprietorship to take on some additional income. What are some tax considerations (deductions, quarterly payment of taxes, etc) I should take?

Hello rafmarino,

Thanks for joining us today!

Your additional income will be subject to regular tax as well as self-employment tax. You can either make the Quarterly estimated tax payments or update your W4 (in case you have a regular W2 income), and increase your withholding from the W2 income.
