Maryland and IRS tax for online business?

Question

I live in maryland and would like making an online shop (commissoning costume) as part time to help pay for school.

I know i have to pay 15.3% to irs for SE tax but:

1. what is the income tax i have to pay to the irs if i make about 12,000$ a year (net income)?

2. What the percent or amount of tax do i pay to the state of Maryland for the net income in #1?

3. Since it is part time, do i need a business license/permit/tader license or other legal document to sell online or at all?

4. When i pay estimate tax to the IRS, does the amount payed to the IRS cover both IRS and Maryland tax owed or do i have to pay sepereatly to IRS and MAryland?

5. What percent i shoud withhold to pay the IRS and Maryland tax? (15.3% SE tax + Income tax % + maryland tax % = ?)

I don't have an accountant now since i'm plannign to only have a part time shop but if i must i will find one. If i need one, how much will they chrage for questioning service or service in general for me?

Answer 1

1. This depends on your TOTAL income and filing status. Get the instructions to form 1040-ES to calculate this. If you are single, no dependents and this is your only income, you are in the 10% tax bracket. Tax on $12000 is $305 after exemptions and standard deduction.

2. Maryland has a nice estimated tax calculator at https://interactive.marylandtaxes.com/pe...

4. Separately

5. see above

You also need to charge sales tax on sales to Maryland and New York.
