Hello JA Customer,
Every Ohio retailer (vendor) making taxable retail sales must obtain a vendor's license, collect sales tax, file tax returns with payments of tax collected and maintain complete records of transactions.
I am giving you a link to a section of the Muskingum County website which contains more information on the vendors license you will need, and this page also has a link to the application form that you will need to complete.
As far as your income taxes, the income you have from selling these crafts is considered income from self employment and you will need to report this income on both your federal and state tax returns at the end of the year. As a self employed person, you will be responsible for federal and state income taxes on your net income from this business, as well as the full share of SS and Medicare taxes.
Since you are self employed and no taxes are withheld from the income you receive, you should make quarterly estimated tax payments to both the IRS and to the state of OH to pay in what approximately you think you will owe at the end of the year. The amount of tax you owe will obviously depend on the volume of business that you do, and the income tax bracket that places you in.
Estimated tax payments are made to the IRS by submitting your estimated tax payment to the IRS along with voucher 1040-ES. Estimated payments are made to the state by sending in your payment along with Form IT 1040-ES.
