No sense in explaining things to the unwilling to learn..
Let me try - what I am about to share is in IRS code and everyone here should make their own decision based on their own research. Meaning, your interpretation is all on you.
You can open a Roth IRA at work and contribute nearly any portion of your pay into a Roth as long as you qualify under the MAGI income limits in US/IRS code 26. Perfectly acceptable and NOT what I am talking about at all since it is NOT a backdoor Roth.
The first step in the backdoor Roth IRA strategy involves making a
nondeductible contribution to a traditional IRA. There are no income limits for making
nondeductible contributions to a traditional IRA, brokerage account or any account that is using
non-qualified taxable money. e.g. you got a nice sum of money from somewhere and you wanna throw 20k into a nondeductible IRA brokerage. You can. You paid tax on the money when you earned it, making it non-qualified money. Once contributed, the money is taxed again at the end of the year as part of dividends earned until you want to withdraw it. Then, the basis amount is not taxed; the gain and interest is taxed as part of your ordinary income and may be subject to Cap Gains (consult your tax professional on how that is accounted) That is where you get hit.
After contributing to the traditional IRA, the individual can convert the funds to a Roth IRA. This conversion involves transferring the funds from the traditional IRA (brokerage) to the Roth IRA. Since the individual has already paid taxes on the
non-deductible contribution to the traditional IRA, the conversion typically incurs little to no additional tax liability but
ONLY as long as there are no earnings on the contributed amount between the time of contribution and conversion. If there are earnings, there may be tax consequences.
The backdoor Roth IRA strategy has the exact same limits as the traditional IRA and Roth IRA contribution limits set by the IRS. The contribution limits for a backdoor Roth IRA tie to those of a traditional IRA and Roth IRA, which can change yearly. As of 2024, individuals under 50 can contribute up to $7,000 annually to an IRA; Those 50 and older can make catch-up contributions of up to $8,000 annually.
