An individual account is a financial account owned by one person, giving that person sole control over deposits, withdrawals, and investment decisions. Because only one name sits on the account, every Form 1099 the institution issues goes out under that owner’s Social Security number, and all of the account’s income lands on their personal Form 1040. That single-owner structure applies whether the account is a checking account, a brokerage portfolio, an IRA, or a 401(k), but the tax treatment shifts sharply from one type to the next.
What an Individual Account Is
One person holds full legal title. The owner can buy, sell, deposit, withdraw, or close the account without anyone else’s signature. Only that owner can name a beneficiary, grant someone access through a power of attorney, or change the registration.
This is different from a joint account, where two or more people share access and tax obligations, and different from an account owned by an entity such as an LLC or a trust. A trust is a separate legal arrangement that files its own return on Form 1041 once it has taxable income or gross income of $600 or more.1Internal Revenue Service. About Form 1041, U.S. Income Tax Return for Estates and Trusts With an individual account, none of that separation exists. The account and the person are treated as one for tax purposes.
How Taxes Work on a Taxable Individual Account
An individual account held outside the retirement system, such as a regular brokerage account, savings account, or CD, has no tax shelter. Income the account produces is taxable in the year it’s earned.
Ordinary Income and 1099 Reporting
Interest from bank accounts and CDs, ordinary dividends, and short-term capital gains on investments held one year or less are taxed as ordinary income at your regular federal rate. Banks issue Form 1099-INT for interest of $10 or more.2Internal Revenue Service. Instructions for Forms 1099-INT and 1099-OID Brokerages issue Form 1099-DIV for dividends at the same threshold.3Internal Revenue Service. Instructions for Form 1099-DIV Copies go to both you and the IRS, so the amounts need to match what you report.
Long-Term Capital Gains
Investments held longer than one year qualify for lower long-term capital gains rates when sold at a profit.4Internal Revenue Service. Topic No. 409 Capital Gains and Losses For 2026, single filers pay 0% on long-term gains up to $49,450 in taxable income, 15% above that, and 20% once taxable income tops $545,500. Married couples filing jointly reach 15% at $98,900 and 20% at $613,700.
Higher earners also pay a 3.8% net investment income tax on top of those rates. The surtax applies once modified adjusted gross income exceeds $200,000 for single filers or $250,000 for joint filers. Those thresholds have never been adjusted for inflation since the tax took effect in 2013, so more taxpayers get pulled in each year.5Internal Revenue Service. Net Investment Income Tax
Using Losses to Cut Your Tax Bill
One advantage of a taxable individual account, compared with retirement accounts, is that losses count. Capital losses first offset capital gains dollar for dollar. If losses exceed gains for the year, you can deduct up to $3,000 of the remainder against ordinary income, or $1,500 if married filing separately.6Office of the Law Revision Counsel. 26 USC 1211 – Limitation on Capital Losses Unused losses carry forward indefinitely. The math runs through Form 8949 with totals moving to Schedule D of your Form 1040.7Internal Revenue Service. About Form 8949 – Sales and Other Dispositions of Capital Assets
Tax-Advantaged Individual Accounts
Most U.S. retirement savings vehicles are built on the individual account structure. Each is legally owned by one person.
Traditional and Roth IRAs
For 2026, the annual contribution limit for both Traditional and Roth IRAs is $7,500. Savers 50 and older can add a $1,100 catch-up, for a total of $8,600.8Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500
The two accounts run in opposite tax directions. Traditional IRA contributions may be deductible now, and the money grows tax-deferred until you withdraw it. Roth contributions are made with after-tax dollars, and qualified withdrawals are tax-free once you’re at least 59½ and have held the account five years.
Income limits apply to both. If you’re covered by a workplace plan, the Traditional IRA deduction phases out between $81,000 and $91,000 of modified AGI for single filers in 2026, and between $129,000 and $149,000 for joint filers. Roth contributions phase out between $153,000 and $168,000 for single filers and between $242,000 and $252,000 for joint filers.8Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500
Going over the limit triggers a 6% excise tax on the excess for every year it stays in the account.9Office of the Law Revision Counsel. 26 USC 4973 – Tax on Excess Contributions to Certain Tax-Favored Accounts and Annuities The penalty compounds annually until you take the excess out.
401(k) and Similar Workplace Plans
A 401(k), 403(b), or most 457 plans hold your assets in an individual account inside a plan trust. The 2026 employee contribution limit is $24,500. The standard catch-up for workers 50 and older is $8,000, for a total of $32,500. Workers ages 60 through 63 get a higher $11,250 catch-up under a SECURE 2.0 provision, allowing deferrals up to $35,750.8Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500
SEP and SIMPLE IRAs
SEP IRAs are funded entirely by employer contributions; employees can’t defer salary in. The employer can contribute up to 25% of compensation, capped at $72,000 for 2026.10Internal Revenue Service. SEP Contribution Limits (Including Grandfathered SARSEPs) SIMPLE IRAs combine employee deferrals with mandatory employer contributions. The 2026 employee deferral limit is $17,000, with a $4,000 catch-up at 50 and older.8Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500
Custodial Individual Accounts for Minors
Minors generally can’t own financial accounts in their own name, but custodial accounts under the Uniform Gifts to Minors Act (UGMA) or Uniform Transfers to Minors Act (UTMA) work around that. An adult custodian manages the account, but the minor is the legal owner, and the account is tied to the child’s Social Security number. Contributions are irrevocable.
When the minor hits the age of majority under state law, typically between 18 and 25, the custodian must hand over control. From that point the former minor can spend the money however they want.
The tax angle is where custodial accounts often disappoint. A child’s unearned income above $2,700 in 2026 can be taxed at the parent’s marginal rate rather than the child’s lower rate under the kiddie tax. It applies to children under 18, to 18-year-olds who don’t earn more than half their own support, and to full-time students ages 19 through 23 who meet the same support test.11Internal Revenue Service. Topic No. 553, Tax on a Child’s Investment and Other Unearned Income
Insurance Coverage if the Institution Fails
Coverage depends on where the account sits, and it protects against the institution collapsing, not against investment losses.
Bank deposits in individual accounts are insured by the FDIC up to $250,000 per depositor, per FDIC-insured bank, per ownership category.12FDIC. Understanding Deposit Insurance Accounts at two different banks are separately insured. Two individual accounts at the same bank share one $250,000 limit.
Brokerage accounts are covered by SIPC up to $500,000 in securities and cash, with a $250,000 sublimit on cash.13SIPC. What SIPC Protects SIPC steps in only when a brokerage becomes insolvent and customer assets are missing. Losses from bad market bets aren’t covered.
Foreign Individual Accounts
If you hold individual accounts at financial institutions outside the United States, two separate federal reports may apply, and they often catch people by surprise.
The Report of Foreign Bank and Financial Accounts (FBAR) is required if the combined value of all your foreign financial accounts exceeds $10,000 at any point during the calendar year.14FinCEN.gov. Report Foreign Bank and Financial Accounts The FBAR is filed with FinCEN through the BSA E-Filing System, not with the IRS.
Form 8938, required under the Foreign Account Tax Compliance Act (FATCA), is separate. A single U.S. resident files it when foreign financial assets exceed $50,000 on the last day of the tax year or $75,000 at any point during the year. For joint filers, the thresholds are $100,000 and $150,000.15Internal Revenue Service. Do I Need to File Form 8938, Statement of Specified Foreign Financial Assets Form 8938 goes in with your tax return, so filing one doesn’t excuse you from the other.
Planning for Incapacity and Death
Because only one person owns the account, no one else has legal authority to touch it if the owner becomes incapacitated. The standard fix is a durable power of attorney, a document naming an agent who can manage your financial affairs if you can’t. The word “durable” is what keeps the authority alive through incapacity; without it, the power of attorney ends exactly when you need it. If no durable power exists, the family typically has to petition a court to appoint a guardian or conservator, which is slow and expensive.
Death raises a different question: where do the assets go? Most banks and brokerages let account holders file a Transfer on Death (TOD) or Payable on Death (POD) designation. The named beneficiary presents a death certificate and takes ownership directly, bypassing probate. Without a beneficiary, the account falls into the probate estate and is distributed under the owner’s will or state intestacy rules.
For taxable accounts holding appreciated investments, the tax outcome at death is favorable for heirs. Under federal law, the cost basis of inherited property resets to fair market value on the date of death.16Office of the Law Revision Counsel. 26 USC 1014 – Basis of Property Acquired From a Decedent Stock bought for $10,000 and worth $100,000 at death gives the heir a $100,000 basis. Sold the next day at $100,000, it produces no capital gains tax. This step-up applies to stocks, bonds, mutual funds, and similar appreciating assets. It does not apply to IRAs and 401(k)s, which heirs pay ordinary income tax on when they take distributions.
Individual account balances count toward the deceased owner’s taxable estate, but the federal estate tax exemption for 2026 is $15,000,000 per person, following the increase in the One, Big, Beautiful Bill signed in July 2025.17Internal Revenue Service. What’s New — Estate and Gift Tax Estates under that threshold owe no federal estate tax. Some states impose their own estate or inheritance taxes at lower thresholds, so the federal number isn’t the full picture everywhere.
