Account Types & Registration

Free and printable — use your browser's print function for a clean copy. Updated 2026-07-05.

Cash Account

  • Must pay in full by settlement date (T+1)
  • No borrowing, no margin
  • Reg T violation if payment not received = frozen account (90 days)

Margin Account

  • Borrow from broker-dealer to buy securities
  • Reg T: 50% initial margin requirement (set by Fed)
  • Minimum maintenance: 25% (FINRA minimum for long positions)
  • Short account maintenance: 30%
  • Margin call if equity falls below maintenance requirement
  • Margin agreement required: credit agreement, hypothecation agreement, loan consent (optional)
  • Pattern Day Trader: 4+ day trades in 5 business days = requires $25,000 minimum equity

Joint Accounts

  • JTWROS (Joint Tenants with Right of Survivorship)
  • When one owner dies, assets pass to the survivor(s)
  • Most common for spouses
  • TIC (Tenants in Common)
  • When one owner dies, their share goes to their ESTATE (not the other owner)
  • Ownership can be unequal

Custodial Accounts (Minors)

  • UGMA (Uniform Gift to Minors Act): Minor owns at age 18
  • UTMA (Uniform Transfer to Minors Act): Minor owns at age 18 or 21 (state-dependent)
  • Gift is IRREVOCABLE — once given, can't take it back
  • Only ONE custodian and ONE minor per account
  • No margin trading, no options, no speculative investments
  • Custodian has fiduciary duty

Trust Accounts

  • Managed by a trustee for beneficiaries
  • Must follow terms of the trust document
  • Trustee has fiduciary duty

Discretionary Accounts

  • Rep can decide what, when, and how much to trade WITHOUT prior client approval per trade
  • Requires WRITTEN authorization (power of attorney / trading authorization)
  • Principal must approve discretionary accounts
  • Each trade must be reviewed by principal promptly
  • Time and price do NOT make an account discretionary
  • If client says "buy 100 shares of Apple when you think the time is right" = NOT discretionary (only time/price discretion)

Key facts to memorize

  • Reg T: 50% initial margin (set by Fed)
  • Maintenance: 25% long, 30% short (FINRA minimum)
  • Pattern day trader: 4 day trades in 5 days = $25K minimum
  • JTWROS: right of survivorship; TIC: share goes to estate
  • UGMA: age 18; UTMA: age 18 or 21 (state dependent)
  • Discretionary: choosing WHAT to trade (not just time/price)
  • Written authorization required for discretionary accounts

Mnemonics that stick

  • "JTWROS = Joint, when one dies the Right goes to the Other Survivor"
  • "TIC = share goes To Inheritors (through estate), not the other tenant"
  • "UGMA = 18, UTMA = 21 (in most states — U-T-M-A has more letters = more years)"
  • "Reg T = 50% — the T looks like a fraction bar, half and half"
  • "Pattern Day Trader = 4 in 5 = $25K minimum"
  • "Discretionary = Deciding WHAT to buy — time/price alone is NOT discretionary"

Exam traps

  • Choosing only TIME and PRICE is NOT discretionary — choosing WHAT security or HOW MANY shares IS discretionary
  • UGMA/UTMA accounts: gifts are IRREVOCABLE, no margin, no options
  • JTWROS: survivor gets everything; TIC: estate gets deceased's share
  • Pattern day trader: 4+ day trades in 5 business days requires $25K equity
  • Margin initial requirement (Reg T) = 50% — set by the FED, not FINRA
  • FINRA sets MINIMUM maintenance margin (25% long, 30% short) — firms can set higher
