yes you do
different cities and towns have different laws. Most larger cities require you to have permit. Smaller towns usually don't make you have a permit. Check wih local authorities to see about your town.
A garage sale can be a fun way to make extra money and create extra space in your home. Some places do require you to have a permit before you have a sale. In Simi Valley, you do not need a permit. The exception being if you are a business then you will need a temporary use permit.
No. It is illegal to have a garage sale without a business permit in 9 states, including CA
If the sale is via the internet and the California seller has no Illinois location, then no, you don't need to charge Illinois sales tax. You'll need to consult California tax law to know whether to charge him California tax, but probably don't need to charge it either. If the sale is in person in California, then yes, you should charge him California sales tax. If the sale is via the phone you could probably get away with calling it an internet sale and skip the tax, although it depends more on California tax law than Illinois tax law.
no that's the dumbest thing ever
You probably need to contact your local authorities. They will give you instructions on how to get a permit, if you need one.
In most states yes you do. Check with your local liquor control and see if you can get a one day permit
If you will be selling them as part of a garage sale or non-profit event, you don't need a license. If you want to start a business, you will need a business license and a permit from the Health Department.
Usually.
sometimes you need a permit because you're making money in a public area. In most places there are car boot sales and you pay a small fee to sell whatever you have. the car boot sales are normally held in schools or markets.
Actually depends on your town ordinance. Just because you have a yard sale without a permit does not mean one does not need to be obtained. Check with your town hall to be sure you are not fined! Some towns fine $100 per day of non-permitted yard sales.
Pretty much anywhere. You may need to get a permit from your local government first though.
