What to check before choosing a broker in the USA
The US has the world's most developed retail investing ecosystem — commission-free trading, excellent tax-advantaged accounts, and strong regulatory protection. Here's what every US investor should know.
1. Check SEC + FINRA registration. US broker-dealers must be registered with the SEC (Securities and Exchange Commission) and be members of FINRA (Financial Industry Regulatory Authority). Verify any broker at BrokerCheck.finra.org. Investment advisers (RIAs) are registered with the SEC or state regulators — verify at the SEC's IAPD database.
2. Maximise tax-advantaged accounts first. The US has the world's best-developed retirement account system. A 401(k) with employer match is essentially free money — contribute at least enough to get the full match. Then max out a Roth IRA ($7,000/year in 2024-25) for completely tax-free growth and tax-free withdrawals in retirement. If self-employed, a SEP-IRA or Solo 401(k) allow much higher contributions. Only after these are maxed should you invest in a taxable brokerage account.
3. Long-term capital gains rates are preferential. Holding investments for more than 12 months qualifies for the long-term capital gains (LTCG) rate — 0%, 15%, or 20% depending on income (vs. up to 37% for short-term gains taxed as ordinary income). A 3.8% Net Investment Income Tax (NIIT) also applies to investment income for individuals with MAGI above $200,000 (single) or $250,000 (married). The difference between short-term and long-term rates is significant — a tax-inefficient strategy can dramatically reduce returns.
4. Zero-commission trading is now standard. All major US brokers — Interactive Brokers, Schwab, Fidelity, Robinhood — offer $0 commissions on US stock and ETF trades. Revenue now comes from payment for order flow (PFOF), interest on cash, and margin lending. Compare the actual total cost including spreads, not just commission.

How to Get Started with Best Brokers in the USA
1
Choose an SEC/FINRA-registered broker
All US broker-dealers must be registered with the SEC and FINRA. Verify at BrokerCheck.finra.org — this shows registration status, any disciplinary history, and qualifications. US citizens need a Social Security Number (SSN) or ITIN to open an account. Non-US residents generally cannot open US domestic brokerage accounts.
2
Prioritise tax-advantaged accounts
Open in this order: (1) 401(k) up to employer match — free money; (2) Roth IRA — $7,000/year completely tax-free growth; (3) HSA (if eligible) — triple tax advantage; (4) Traditional IRA or 401(k) maximum; (5) 529 (education savings); (6) taxable brokerage for anything beyond these. Always maximise tax-advantaged space before taxable accounts.
3
Fund via bank transfer or wire
Fund via ACH bank transfer (free, 1-3 business days), wire transfer (same day, fees may apply), or check deposit. Major US banks (Chase, BofA, Wells Fargo, Citi) are all supported. Most brokers allow instant buying power of up to $1,000 while ACH settles. New accounts should use ACH from a checking account for the fastest setup.
4
Report gains to the IRS
All capital gains are reported to the IRS (Internal Revenue Service) on Schedule D of your Form 1040. Your broker provides Form 1099-B at year-end listing all taxable transactions. Short-term gains (held ≤12 months): taxed as ordinary income, up to 37%. Long-term gains (held >12 months): 0%, 15%, or 20% based on income. Wash sale rules: losses cannot be claimed if you repurchase the same security within 30 days.

Primary Regulators
SEC (Securities and Exchange Commission) —
sec.gov. Regulates securities markets, broker-dealers, investment advisers, and public companies.
FINRA (Financial Industry Regulatory Authority) — self-regulatory organisation for broker-dealers.
CFTC (Commodity Futures Trading Commission) — regulates futures, swaps and certain derivatives.
FDIC (Federal Deposit Insurance Corporation) — regulates and insures bank deposits.
SIPC Protection
✅ SIPC (Securities Investor Protection Corporation) — covers up to $500,000 per customer in securities (including up to $250,000 in cash) if a broker-dealer fails. SIPC is not a government agency but a non-profit member corporation funded by broker-dealers. It does NOT cover market losses — only broker failure. Many major brokers carry additional private excess SIPC coverage of $150 million+ per customer.
Bank Deposit Protection
✅ FDIC (Federal Deposit Insurance Corporation) — insures bank deposits up to $250,000 per depositor per bank per ownership category. Applies to checking, savings, money market, and CD accounts at FDIC-member banks. Brokerage cash held in money market mutual funds is NOT FDIC insured — only cash swept into FDIC bank accounts. FDIC is backed by the US government.
PDT Rule
⚠️ Pattern Day Trader (PDT) rule — if you execute 4+ day trades in a 5-business-day period in a margin account with less than $25,000, your account is flagged as a Pattern Day Trader and you must maintain $25,000 minimum. This applies only to margin accounts, not cash accounts. Cash accounts have no PDT restriction but are subject to settlement rules (T+1 settlement from May 2024).
Short-Term CGT (STCG)
Assets held 12 months or less — gains taxed as ordinary income at marginal rates: 10%, 12%, 22%, 24%, 32%, 35%, or 37% (2024 rates). Plus 3.8% NIIT for high earners. Short-term gains can significantly erode returns — always consider tax consequences before selling a position held less than 1 year.
Long-Term CGT (LTCG)
Assets held more than 12 months — preferential LTCG rates: 0% for income up to ~$47,025 (single, 2024); 15% for most taxpayers; 20% for incomes above ~$518,900 (single). Plus 3.8% NIIT (Net Investment Income Tax) for MAGI above $200,000 (single) or $250,000 (married). Maximum effective LTCG rate: 23.8%.
Qualified Dividends
Qualified dividends (from US corps and qualifying foreign corps, held 60+ days) are taxed at LTCG rates (0%, 15%, 20%). Ordinary dividends are taxed as ordinary income. Most common stock dividends from US companies qualify. REITs typically pay non-qualified dividends taxed as ordinary income. Check your 1099-DIV from your broker for the split between qualified and ordinary dividends.
Crypto Tax
The IRS treats crypto as property — the same CGT rules apply: short-term (held ≤12 months) at ordinary income rates; long-term (held >12 months) at LTCG rates. Every crypto-to-crypto trade, purchase with crypto, and crypto-to-fiat conversion is a taxable event. Crypto staking, mining, and airdrop income is ordinary income at receipt. The IRS requires all taxpayers to answer the crypto question on Form 1040.
State Taxes
Most US states also tax capital gains as ordinary income at state rates — California (13.3%), New York (10.9%), Oregon (9.9%). Nine states have no income tax: Florida, Texas, Nevada, Washington, South Dakota, Wyoming, Alaska, New Hampshire (no wage tax), Tennessee (no wage tax). State tax significantly affects the total effective rate — high earners in California can face combined federal + state CGT of 37.1% (short-term).
Wash Sale Rule
The wash sale rule prevents claiming a tax loss if you repurchase the same or substantially identical security within 30 days before or after the sale. The disallowed loss is added to the cost basis of the new position. The wash sale rule currently does NOT apply to cryptocurrency (IRS 2025 guidance was pending — verify current status). Tax-loss harvesting must account for this rule.
Roth IRA
$7,000/year (2024-25)$8,000 if age 50+ After-tax contributions; all growth and qualified withdrawals are completely tax-free. No RMDs (required minimum distributions). Available if MAGI < $161,000 (single) or $240,000 (married) for 2024. Backdoor Roth IRA available for high earners. The Roth IRA is the most powerful long-term tax-advantaged account available — all compounding is tax-free, and withdrawals in retirement are tax-free.
Traditional IRA
$7,000/year (2024-25) Pre-tax contributions deductible if no workplace plan or if income below threshold. Tax-deferred growth. Withdrawals in retirement taxed as ordinary income. RMDs required from age 73. Best for investors who expect to be in a lower tax bracket in retirement.
401(k)
$23,000/year (2024)$30,500 if age 50+ Employer-sponsored defined contribution plan. Pre-tax (traditional 401k) or after-tax (Roth 401k) contributions. Many employers match contributions — this is free money. Total limit (including employer match): $69,000 (2024). Self-employed: Solo 401(k) allows $69,000/year.
HSA
$4,150/year individual (2024)$8,300 family Health Savings Account — triple tax advantage: contributions are pre-tax, growth is tax-free, withdrawals for qualified medical expenses are tax-free. After age 65, HSA funds can be used for any purpose (taxed as ordinary income, like a Traditional IRA). Only available if enrolled in a High-Deductible Health Plan (HDHP).
529 Plan
State-sponsored education savings plan. After-tax contributions grow tax-free; withdrawals for qualified education expenses are tax-free federally (state tax varies). Contribution limits are high (total balances can reach $500,000+ before triggering gift tax). SECURE 2.0 Act (2022) allows rolling up to $35,000 of unused 529 funds into a Roth IRA.
Domestic Exchanges
NYSE (New York Stock Exchange) — world's largest by market cap; S&P 500 and Dow Jones Industrial Average. NASDAQ — technology-heavy exchange; NASDAQ Composite and NASDAQ-100. CBOE — derivatives and options. US equities market cap exceeds $50 trillion — roughly 40%+ of global market cap. Trading hours 09:30–16:00 ET; pre-market and after-hours available at many brokers.
Accredited Investor
Accredited Investor status: net worth exceeding $1 million (excluding primary residence) OR annual income exceeding $200,000 ($300,000 joint) in each of the last 2 years. Accredited investors can access private placements, hedge funds, and other unregistered securities. Knowledgeable employees of private funds also qualify. Regulation D permits private fundraising only from accredited investors.
Offshore / International Access
US investors have unrestricted access to international markets through US-registered brokers like Interactive Brokers and Schwab International. However, US persons face restrictions: many foreign brokers refuse US clients due to FATCA compliance costs. US investors cannot purchase most non-US domiciled ETFs and mutual funds due to PFIC (Passive Foreign Investment Company) tax rules — US-domiciled ETFs are significantly more tax-efficient.
What US Investors Need to Know in 2026
The US market in 2026 is characterised by complete commission-free trading across all major brokers. The T+1 settlement rule (implemented May 2024) means trades now settle the next business day — improving capital efficiency for active traders. The Roth IRA remains the single most powerful account available to most US investors — $7,000/year of completely tax-free compounding for life is unmatched globally.
For the pure long-term investor, Fidelity and Schwab offer comparable features: zero-commission US stocks and ETFs, excellent retirement account options (including fractional shares), and outstanding customer service. Fidelity's ZERO expense ratio index funds (0.00%) are unique in the industry. Interactive Brokers stands out for global market access, low margin rates, and sophisticated tools — ideal for investors wanting exposure beyond US markets or lower financing costs.
Robinhood democratised investing for a new generation but carries trade-offs — payment for order flow (PFOF) means execution may be slightly inferior to Schwab or Fidelity for large trades. For retirement-focused investors, Fidelity's research, no-fee IRA, and 24/7 customer service make it the strongest all-around choice.

Frequently Asked Questions
How is capital gains tax calculated in the US? +
US CGT depends on your holding period. Short-term (held 12 months or less): taxed as ordinary income at marginal rates up to 37%. Long-term (held more than 12 months): preferential rates of 0% (up to ~$47k income for single filers), 15% (most taxpayers), or 20% (high earners). A 3.8% Net Investment Income Tax (NIIT) also applies if your MAGI exceeds $200,000 (single) or $250,000 (married). Most states also tax capital gains — California adds up to 13.3% on top of federal rates. Strategies to minimise: hold investments 12+ months, harvest losses to offset gains, and maximise Roth IRA contributions for tax-free growth.
What is a Roth IRA and why is it so valuable? +
A Roth IRA is a retirement account funded with after-tax money. The key benefit: all growth and qualified withdrawals are completely tax-free. You contribute $7,000/year ($8,000 if 50+) after paying income tax, but every dollar of gains, dividends, and interest you earn inside the Roth IRA for the rest of your life is tax-free. Unlike Traditional IRAs, Roth IRAs have no required minimum distributions. Eligible if MAGI < $161,000 (single) or $240,000 (married) for 2024. For high earners above these limits, the "backdoor Roth IRA" (non-deductible Traditional IRA contribution converted to Roth) achieves the same result. Most long-term investors benefit from maxing out a Roth IRA before any taxable account.
What is SIPC protection and does it cover market losses? +
SIPC (Securities Investor Protection Corporation) protects brokerage customers if a broker-dealer fails — it covers up to $500,000 in securities (including $250,000 in cash) per customer. SIPC does NOT protect against market losses — if your stocks decline in value, SIPC provides no coverage. It only protects against broker failure (fraud, insolvency). Most major brokers (Fidelity, Schwab, Interactive Brokers) also carry additional excess SIPC insurance of $150 million–$1 billion per customer through Lloyd's of London or similar insurers. Cash held in FDIC-insured bank accounts (via cash sweep) is protected separately up to $250,000 by the FDIC.
