I am an independent contractor this year for the very first time in my life, and I want to make sure I’m not missing anything to be compliant with the IRS. I am asking my clients for a 1099 NEC to be filed, and am ready to pay income and self employment tax (this year my tax will likely be under $1,000 so I am not making estimated payments but paying tax at filing). Is there anything else I should be sure to do aside from this? Do I need to register for any certificate or license for my sole proprietorship with local city or state authorities?
