TL;DR

• Held away assets are client-owned accounts, old 401(k)s, outside brokerage accounts, HSAs, cash, that sit outside an advisor’s management and visibility.
• Wallet share is directly tied to income: 61.5% of advisors earning $1M or more manage 76 to 100% of client assets, while advisors earning under $500,000 typically manage just 25 to 50%.
• Advisors usually assume clients hold 1 to 2% of assets in cash elsewhere. The real figure is closer to 20%.
• A four-step process, onboarding questions, tax document review, an aggregation decision, and ongoing maintenance, closes this gap in a repeatable way.
• Discovery alone doesn’t solve the problem. Aggregated data decays through broken feeds and stale balances unless someone actively maintains it.

Held away assets are the financial accounts a client owns but an advisor doesn’t manage, and they represent a bigger blind spot than most advisors assume. This guide walks through a four-step process to identify and aggregate them, starting with what actually counts as a held-away asset.

What Are Held-Away Assets

Held-away assets are financial accounts and holdings a client owns that sit outside the advisor’s management. Common examples:

• Old 401(k)s and 403(b)s left with former employers
• Health savings accounts (HSAs)
• Outside brokerage accounts
• Cash in savings, money market, or CD accounts
• Equity compensation
• Inherited IRAs
• Accounts managed by another advisor or firm

These assets are still the client’s wealth. They’re just invisible to the advisor unless someone actively goes looking for them.

Why Advisors Only See a Fragment of Client Wealth

The size of this blind spot is measurable, and it’s tied directly to advisor income:

• 61.5% of advisors earning $1 million or more manage 76 to 100% of their clients’ total investable assets
• Advisors earning under $500,000 typically manage just 25 to 50% of client assets
• Advisors commonly estimate clients hold 1 to 2% of assets in cash elsewhere; when clients are asked directly, the number is closer to 20%
• An estimated 40% of a high-net-worth client’s total portfolio may sit held away at any given time
• At the largest scale, Citi and Morgan Stanley executives have each estimated roughly $5 trillion in client assets held at other institutions

This isn’t a client-type problem. It’s a discovery problem, and it’s fixable with a repeatable process.

Steps to Identify and Aggregate Held-Away Assets

Step 1: Ask the Right Questions During Onboarding

The most direct discovery method is also the most underused: asking specifically, not generically. Effective onboarding questions include:

• “Do you have any bank accounts or life insurance policies we haven’t discussed?”
• “Is it possible you have an old 401(k) with a former employer, or an inheritance you’re not actively managing?”
• “Do you hold real estate investments, like a rental property or mortgage notes?”
• “Do you work with another financial advisor for any part of your portfolio?”
• “Are you satisfied with how your outside assets are currently being managed?”

These land better inside a goals-based planning conversation than as a standalone disclosure form. Framed as part of understanding a client’s full financial picture, not as an audit, clients are generally forthcoming.

Step 2: Review Tax Documents for Discovery Signals

Conversations catch what clients remember to mention. Tax documents catch what they don’t. A review of Schedule B and Schedule D on a client’s tax return surfaces:

• Interest and dividend income (Schedule B) that may point to CDs, savings accounts, or individual stock holdings outside the advisor’s view
• Capital gains activity (Schedule D) from brokerage accounts the advisor doesn’t manage

Large interest income from an unfamiliar source, for example, often points to a CD or account the client didn’t think to mention during onboarding. It’s a natural, low-friction opening for a consolidation conversation. Newer IRS-verified data tools can now surface similar information, W-2 income, 1099s, retirement distributions, directly, without the client needing to upload or scan anything.

Step 3: Decide Between Manual Entry and Account Aggregation Technology

Once held-away assets are identified, the next decision is how to track them:

What Account Aggregation Software Actually Does

Account aggregation technology pulls balances and transaction history from linked outside accounts automatically, often daily. Adoption is high: 74% of advisors had adopted account aggregation technology as of a 2023 Kitces report, one of the highest adoption rates of any advisor technology category. It removes the manual work of chasing down statements and re-entering data by hand.

 When Manual Tracking Still Makes Sense

For smaller practices or a limited number of held-away accounts, manually logging balances during periodic reviews can be a reasonable starting point. It’s slower to update and more prone to going stale between reviews, but it avoids the cost and setup of a dedicated platform. The right choice depends on how many held-away relationships a practice is actually tracking, not a fixed rule.

Step 4: Keep the Picture Current, Not Just Accurate on Day One

This is the step most practices skip entirely, and it’s where the real risk sits. Aggregated data doesn’t stay accurate on its own:

• Data feeds break when an institution updates its website, requires a password reset, or adds two-factor authentication
• Balances can sit stale for weeks before anyone notices a connection failed
• A picture that was complete after onboarding is often materially wrong by month six, not because the advisor did anything wrong, but because nobody was actively maintaining it

Consider two hypothetical practices that both did excellent discovery work at onboarding, following Steps 1 through 3 closely. Practice A reviews the aggregated picture only at annual meetings. Practice B has a system that flags when a linked account goes stale or disconnects. A year later, Practice A is making recommendations based on partially outdated data without realizing it. Practice B catches the gap as it happens.

This is the specific problem SmartSync is built to solve. Rather than treating discovery as a one-time onboarding task, SmartSync keeps a client’s financial account picture current on an ongoing basis, surfacing new and changed accounts as they appear instead of waiting for the next annual review to notice something’s missing. It’s worth pairing with the retention practices covered in Financial Advisor Client Retention: A Complete Guide, since an accurate, current picture of a client’s full wealth is also one of the clearest ways to demonstrate value during the regular contact that guide recommends.

How SmartHeritance Fits Into This Process

The four steps above work regardless of which platform an advisor uses. SmartHeritance’s role sits specifically at Step 4, the maintenance gap most practices never solve.

SmartSync approaches account discovery as an ongoing process rather than a one-time sync. Once the onboarding conversation and tax document review are complete, SmartSync keeps scanning for new and changed financial, insurance, and account activity. A held-away asset that surfaces eight months into a relationship gets caught as it happens, not months later at the next annual review. Examples of what SmartSync surfaces on an ongoing basis:

• A new brokerage account a client opens without mentioning it
• A changed HSA balance or contribution pattern
• A newly opened CD or savings account at another institution
• Any account activity that shifts materially from what was recorded at onboarding

A typical aggregation platform only shows what a linked account’s balance is today. SmartSync is built to catch three additional signals:

• When a connection has gone stale and stopped pulling accurate data
• When a new account trail has appeared that wasn’t part of the original picture
• When a client’s overall financial situation has shifted enough that the last review no longer reflects reality

This is the exact failure mode Step 4 describes: data that was correct on day one and wrong by month six, with no one aware of the gap.

For a practice, the value isn’t a new discovery method to replace Steps 1 through 3. Onboarding questions, tax document review, and the manual-versus-aggregation decision still do that work. What SmartSync adds is confidence that the picture built during those steps doesn’t quietly go stale between annual meetings. That ongoing accuracy is the same difference this guide has pointed to throughout: the gap between advisors who manage a fragment of client wealth and advisors who manage most of it.

Frequently Asked Questions:

1. Are held-away assets included in a firm’s official AUM reporting?
   
   No. AUM reporting generally reflects only the assets an advisor directly manages, held-away assets are tracked separately, if at all, and typically aren’t counted toward regulatory AUM figures.
   
2. Do clients pay advisory fees on assets an advisor doesn’t manage?

Generally no, advisory fees are usually charged only on assets under the advisor’s direct management, though some firms offer a lower-cost tier for held-away assets that are simply tracked or aggregated.

3. Is client consent required to use account aggregation technology?

Yes. Clients typically need to authorize linking outside accounts, usually by providing login credentials or approving a secure connection, before an aggregation platform can pull that data.

4. Can held-away assets affect a client’s overall risk profile assessment?

Yes. A risk assessment based only on managed assets can miss significant concentration or cash positions sitting elsewhere, which can lead to recommendations that don’t reflect the client’s true full-portfolio risk.
