@spagirl1550 Good Luck on your new venture.
1. Generally ( and depending on your last years tax filings ) you may or may not have to files estimated taxes each quarter. Note that there are two types of taxes that are required to be current with quarterly ( or be faced with interest charges at least ) --- (a) Federal Taxes and (b) State Taxes ( unless your state of residence has NO Personal Income Tax).
2. All self-employed are also responsible for paying Self-Employment Taxes ( equivalent of FICA for wage earners, called SECA and is at 15.3% of your gross profits ). This does not have to be paid quarterly.
3. You will need to keep good records of all inventory that you buy for use or for sale to customers.
4. If , as you say , you are sole owner ( i.e. a single member LLC ) your file your return on Schedule-C along with your income tax return.
5. Also note that it is strongly suggested that you have separate Business Bank account ( to dela with all expenses and incomes ), a separate Business Credit Card and never, never mingle your personal finances with that of the business.
Please consider getting yourself familiar with reports / suggestions from the SBA -- >
