Wil…that’s correct.
All of your fee is reportable as taxable income - the state-mandated fees you can charge as a notary public (in FL $10//notarization) is exempt from Self-employment tax only. Not sure where you are but if you have a state income tax, you’ll need to check your state regulations about how to handle your notary income on that return.
And yes, a tax advisor or CPA is a good idea if you’re unsure…just be aware that many of them don’t know about the notary exemption. So make sure whoever you use is aware of this.
