Traditional IRA

[chargris]

I roll over my 401K to a Traditional IRA this year (2022). There are no taxes involved when rolling over between retirement accounts.  I know you are able to deposit approximately seven thousand dollars in a year. If I want to make a deposit, how much in added taxes (percentage) do I have to consider? Also, when I withdraw money from my account, how much in added taxes (percentage) do I consider?

You can make a new IRA contribution if you have earnings from wages or a net profit from self employment.  You don't have to add in taxes.  You might qualify to make a deductible IRA contribution.  You get a deduction on your tax return for it.  When you take a distribution it is added to all your other income and taxed at your tax rate.  

Here is pub 590A about Contributions

And 590B for Distributions

A rollover is not a contribution and does not change the amount you can contribute.

You can contribute up to $6000 if you are under age 50, or $7000 over age 50, but your contributions can't be more than your compensation from working.  (Compensation is generally defined as taxable wages or self-employment income.)  Contributions are usually tax-deductible, depending on your other income and whether you or a spouse has a retirement plan at work.  You can also choose to make a non-deductible contribution, although this creates extra paperwork that you have to keep track of for many years.  If you want to make a non-deductible contribution, you may want to open a Roth IRA instead.

Withdrawals from a traditional (pre-tax) IRA are subject to regular income tax, the rates vary between 10% and 39% depending on your other income.  If you are under age 59-1/2, there is an additional 10% penalty for early withdrawal.
