Best Custodial Brokerage Accounts for 2026

A comprehensive family ecosystem: The range of the custodial account options here is essentially unmatched. Beyond the standard UTMA/UGMA accounts, Fidelity provides 529 plans, Roth IRAs for kids, and the truly innovative Fidelity Youth Account. I was particularly impressed by the Youth Account, which allows teens aged 13 to 17 to own and manage their own brokerage account with parental oversight. Allowing teens to trade stocks and ETFs while receiving in-app rewards for completing financial literacy lessons is a great way to put them on the road to true financial independence.

Educational depth for every stage: Fidelity’s commitment to education is visible through its dedicated "Becoming a Parent" and "Life Events" sections. I found the workflow for navigating these resources intuitive. The platform uses design paradigms like carousels and filtered content cards that make complex topics like estate planning or 529 tax advantages digestible. The inclusion of a "Save for Later" feature is a thoughtful touch for busy parents who may find a relevant article but lack the immediate time to analyze the nuances of gift tax limits or contribution rules.

Superior research and management tools: Managing a child’s portfolio requires the same quality of tools as a personal retirement account, and Fidelity does not compromise here. The mobile app is sleek and modern, providing a "Discover" tab that blends short-form educational content with real-time market research. For parents building a passive portfolio for their children, the ability to set up recurring investments into ETFs is a standout feature that automates the long-term wealth-building process.

Jessica's take

"Fidelity treats 'minor investing' as a continuous financial journey rather than a single product. By offering the Youth Account alongside traditional custodial structures, they allow a child to grow from a passive beneficiary into an active, educated participant in their own financial future."

Fidelity’s mobile app makes learning on the go super easy with its “On Our Radar” videos which are quick social media style clips that cover everything from market trends to investing basics. They're short, smart, and actually fun to watch, making it simple to stay informed without feeling overwhelmed. It’s a great way to pick up insights in just a few minutes.

Expert-level minor investing education: The quality of Schwab’s educational content is where this firm truly pulls ahead of the competition. When researching the best custodial account options, I was struck by the "Onward" magazine and the high-production value of their "Investing Basics" videos. Unlike the dry, text-heavy PDFs found elsewhere, Schwab’s videos use clear graphics to explain nuanced concepts like how 529 plans can now be converted into Roth IRAs, which is a critical update for modern family planning.

Goal-driven planning tools: I found the workflow for college planning exceptionally comprehensive. Schwab’s college savings calculator and the "Portfolio Checkup" tool allow parents to move beyond guesswork. The checkup tool is highly effective, as it uses an Investor Profile Questionnaire (IPQ) to compare your current custodial holdings against a recommended asset allocation based on your specific risk tolerance. I appreciated how the tool provides detailed risk analysis, including beta and standard deviation, which is vital when managing a portfolio with a fixed time horizon, such as a child approaching college age.

Sophisticated management for the long term: Management is simplified through a dedicated "Money Movement" tab, which centralizes transfers, bill pay, and wire requests. For those looking to build a child's portfolio with high-quality equities, Schwab offers "Stock Slices," their version of fractional shares, starting at just $5. While they lack fractional shares for ETFs, their 24/5 trading capabilities on hundreds of securities provide the flexibility that busy parents need.

Schwab’s web-based stock screener stands out with advanced filtering tools that include forward-year P/E ratios, projected EPS growth, and revenue estimates—ideal for forward-looking investors. The platform allows users to screen for S&P 500 stocks based on future performance metrics, earnings surprises, and Schwab Analyst Ratings. Unlike many screeners that focus solely on historical data, Schwab helps investors identify high-potential opportunities based on forward projections.

Institutional-grade tracking: The true power of managing a minor's assets at IBKR lies within the PortfolioAnalyst dashboard. I was thoroughly impressed by the ability to evaluate a custodial account’s performance using professional risk measures like the Sharpe ratio, standard deviation, alpha, and beta. Furthermore, the impact lens allows parents to align their child’s investments with specific family values, filtering out unwanted industries while seeking out companies that score highly on environmental and social metrics.

Advanced tax optimization: Managing the unearned income of a minor can create complicated tax liabilities, which is where the newly enhanced Tax Planner becomes essential. I found the tax-lot matching and tax loss harvesting features invaluable for projecting year-end taxes across multiple accounts. By allowing you to simulate the tax impact of selling a specific lot before executing the trade, IBKR ensures that the assets meant for your child’s future remain protected from unnecessary tax drag.

Interactive Brokers’ Connections tab, shown here for NVIDIA (NVDA), gives investors a 360° contextual research view by linking the selected stock to related competitors, thematic sectors like AI infrastructure and data centers, and tradable products such as Forecast Contracts and ETFs. Connections helps traders uncover peers, trends, and broader market relationships beyond just the price quote.

Merrill provides the essential structures for a solid custodial account, including 529 plans and UTMA/UGMA accounts. I found the "Guidance and Retirement Center" particularly valuable for its life-stage approach. It offers a dedicated college planning journey that helps parents prioritize goals and select investments. The "Idea Builder" tool is also a great tool for parents, allowing you to discover ETFs and stocks based on forward-looking themes like AI or sustainability, rather than just dry financial ratios.

The true takeaway for Merrill is their industry-leading Tax Resource Center. Attempting to understand the unearned income tax and cost-basis reporting for a minor can be a headache, but Merrill simplifies this with clear FAQ sections on wash sales and automated links to tax software. While they lack custodial Roth IRAs and fractional shares, their "Dynamic Insights" dashboard provides a professional, holistic view of your child’s portfolio performance against the broader market. For those who value having their banking, rewards, and children's savings under one digital roof, Merrill is a highly recommended choice.

Portfolio management: Once the account is funded, managing a child's portfolio is remarkably straightforward. You gain direct access to Morgan Stanley’s premium research and curated mutual fund choice lists, making E*TRADE a highly capable specialist for parents actively managing tax-advantaged educational funds.

Tax resource center: To ensure those funds are managed effectively over the long term, I highly recommend utilizing E*TRADE's exceptional tax resource center. Managing the unearned income of a minor can introduce complexities like gift tax limits or unearned income tax thresholds, and I found their comprehensive guides and contextual FAQs on cost basis methods to be perfectly executed. Furthermore, the platform's risk assessment tool allows you to stress-test your child's portfolio against historical market events, such as the 2008 financial crisis, providing a valuable perspective when balancing aggressive growth with wealth preservation.
