Are IRA's roth and traditional 100% tax defered? Are there different rates of returns for IRA's?

Where do you purchase IRA's, can you buy one on line? Thank you for your help and input.

"Tax deferred" means that you don't pay taxes each year while the IRA is invested and grows.

A traditional IRA is both tax deductible and tax deferred.
If eligible, the money put in is deducted from current income, the IRA grows untouched (at whatever rate you can get!) and when you withdraw the money, it's taxed as ordinary income.
(Just avoid putting "non-deductible" money into an IRA.)

A ROTH is tax deferred. You fund it with after tax dollars and then it grows untouched (again at whatever rate you can get). If you reach 59.5, both the contributions AND the earnings will be tax free.

You purchase IRAs at banks and brokerage houses. Due to a lousy return on one IRA I have (it's the only one that lost money this year), I'm in the process of closing it and rolling the money into another one of my IRAs.

Only traditional up to $2000 per year. Rates do vary so check around.

You can buy them on-line after submitting documents required to set up the IRA. E-Trade, Scott Trade and other on-line brokers offer them.

Traditional IRA contributions reduce your tax when you contribute them, then withdrawals are fully taxable including any increase in their value.

The Roth IRA is not deductible when contributed, but withdrawals, including increases in value, are not taxed unless you withdraw too soon.

Traditional IRA's are tax deferred. Growth in a Roth IRA is tax free.

There are a number of ways to invest IRA money, and rates of return can vary widely - if you invest poorly, it's possible to LOSE money in an IRA.
