A traditional IRA is an individual retirement arrangement (IRA), established in the United States by the Employee Retirement Income Security Act of 1974 (ERISA) (, codified in part at ). Normal IRAs also existed before ERISA. The IRA is held at a custodian institution such as a bank or brokerage, and may be invested in anything that the custodian allows (for instance, a bank may allow certificates of deposit, and a brokerage may allow stocks and mutual funds). Unlike the Roth IRA, the only criterion for being eligible to contribute to a Traditional IRA is sufficient income to make the contribution. However, the best provision of a Traditional IRA — the tax-deductibility of contributions — has strict eligibility requirements based on income, filing status, and availability of other retirement plans (mandated by the Internal Revenue Service). Transactions in the account, including interest, dividends, and capital gains, are not subject to tax while still in the account, but upon withdrawal from the account, withdrawals are subject to federal income tax (see below for details). This is in contrast to a Roth IRA, in which contributions are never tax-deductible, but qualified withdrawals are tax free. The traditional IRA also has more restrictions on withdrawals than a Roth IRA. With both types of IRA, transactions inside the account (including capital gains, dividends, and interest) incur no tax liability. According to IRS pension/retirement department as of July 13, 2009, Traditional IRAs (originally called Regular IRAs) were created in 1975 and made available for tax reporting that year as well. The original contribution amount in 1975 was limited to $1,500 or 15% of the wages/salaries/tips reported on line 8 of the Federal form 1040 (1975). Traditional IRA contributions are limited as follows: * ==Advantages== * The primary benefit of any tax deferred savings plan, such as an IRA, is that the amount of money available to invest is larger than would be the case with a post-tax savings plan, such as a Roth IRA. This means that the multiplier effect of compound interest, or for example, larger reinvested dividends, will yield a larger sum over time. Financial institutions also generally give higher rates of interest to larger sums invested in instruments such as certificates of deposit. The risk is that over a significant period of time the eventual rate of income tax levied on withdrawal is unknowable and could be higher than originally anticipated. * While many people think that the reduction in taxes in the year of contribution is a benefit, that is not necessarily the case. While it is true that the unpaid taxes can be immediately invested and continue to grow, taxes on these gains will need to eventually be paid—either on an ongoing basis, if invested in a non-tax-deferred vehicle (e.g. if pre-tax options are already maximized), or at withdrawal otherwise. Assuming that both the tax deduction and the tax on its reinvestment gains only affect the individual's top tax bracket, the results are tax-neutral. Any potential benefits of claiming and reinvesting a tax deduction come from the expectation that the taxpayer may be in a lower tax bracket during retirement.〔(【引用サイトリンク】url=http://www.goldirabuyersguide.net/gold-ira-rollover-protecting-your-retirement-savings-and-avoiding-tax-penalties/ )〕 * The only benefit that everyone receives is the income's protection from tax. This equals the dollars of tax that would have been paid on the income if earned in a taxable account. It exactly equals the benefit of a Roth IRA. * Unlike a Roth IRA, there is another possible benefit (or penalty) equal to the reduction (or increase) in tax rates between the contribution and withdrawal, multiplied by the dollars withdrawn. Many taxpayers expect to be in a lower tax bracket in retirement. While the tax benefits from contributions are considered to be at the contributor's marginal tax rate, the withdrawals may add income at lower progressive tax brackets. * An IRA protects wealth from creditors, but also cannot be used as collateral when borrowing. * With a Traditional IRA, one always has an option to convert to a Roth IRA; whereas a Roth IRA cannot be converted back into a Traditional IRA. One can choose an optimal (lowest tax rate) time to convert over one's life. Because you have a right, but not an obligation, to convert, this is like an option in finance. As with options in finance, this flexibility, which allows one to hedge future uncertainty, adds some additional value to the Traditional IRA. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Traditional IRA」の詳細全文を読む スポンサード リンク
