How Retirees Find a Flat Fee Financial Advisor

This guide is for retirees and near-retirees with substantial savings, roughly $1 million or more, who want ongoing advice but don't want a bill that rises every time the market does. For you, the fee model matters. What the fee actually covers matters more, and in retirement the biggest piece of that is tax planning.

What "flat fee" actually means

A flat fee advisor charges one set dollar amount per year, usually billed monthly or quarterly. The price is based on how complex your situation is, not how much money you have. If your portfolio grows from $2 million to $2.5 million, your fee may very well stay the same.

Several similar-sounding terms mean something different:

• Fee-only means you're the only one paying the advisor. The advisor does not receive commissions on insurance, annuities, or funds. Fee-only advisors can still charge a percentage of your assets, hourly, or a flat-fee.
• Fee-based sounds nearly identical but means the advisor charges you a fee and can earn commissions on products.
• Assets under management (AUM) pricing is a percentage of your invested balance, often around 1% a year. On $2 million, that's $20,000.
• Hourly or project advisors bill for one piece of work, like a single plan or a Social Security analysis, with no ongoing relationship.

Also watch for firms that charge a flat fee for the plan, then a percentage on top for managing your investments.

Why the fee model matters more once you retire

The cost difference grows over time, and retirement is full of decisions about moving money out of your portfolio.

Start with the cost. To compare a flat fee with a percentage fee, divide the flat fee by the percentage. A $12,000 flat fee equals a 1% fee on $1.2 million. Below that balance, the percentage fee costs less. Above it, the flat fee costs less, and the gap widens every year your portfolio grows. At $3 million, that same 1% is $30,000 a year.

Your advisor's incentives or conflicts of interest also play a role. For example, a fee-based advisor may earn their paycheck by selling insurance. Can they be knowledgeable and help your retirement? Of course. But you should know their way of life depends on selling you an insurance policy.

Likewise, under a percentage fee, your advisor earns more when money stays in the accounts they manage and less when it leaves. While you're working, that rarely matters, because you're mostly adding money.

In retirement, many good decisions involve taking money out:

• Drawing down savings so you can delay Social Security to 70
• Paying off a mortgage
• Gifting to children or grandchildren
• Buying an annuity
• Giving to charity directly from your IRA
• Doing a Roth conversion and paying the taxes

Each of these lowers a percentage-based advisor's pay. Many of those advisors will still give you honest advice. You just shouldn't have to hope they are not being influenced by their compensation. With a flat fee, the advisor is paid the same either way.

Importance of tax planning

For most retirees, taxes are the largest expense they can still control. That makes tax planning the best test of whether any advisor, flat fee or not, is worth hiring. Here's what it should cover:

Roth conversions

Moving money from a traditional IRA to a Roth IRA means paying tax now so future withdrawals, including your heirs', come out tax-free. The best window is often the years after you stop working but before required minimum distributions begin at 73 (75 if you were born in 1960 or later). A good advisor revisits the amount every year instead of setting it once.

Medicare surcharges

Medicare charges higher premiums when your income crosses certain lines, a surcharge called IRMAA (income-related monthly adjustment amount). In 2026, the standard Part B premium is $202.90 a month. A married couple whose 2024 income topped $218,000 pays more. Because it's based on your tax return from two years earlier, a Roth conversion or large capital gain can trigger it long after the fact. An advisor can also help you appeal IRMAA surcharges when you are eligible.

Withdrawal planning

Which account you draw from each year, whether IRA, taxable brokerage, Roth, or cash, affects your tax bill for decades to come. The right order depends on your tax brackets, your Social Security timing, spending goals, and what you want to leave behind.

Charitable giving

Once you're 70½, you can give directly from your IRA through a qualified charitable distribution (QCD), up to $111,000 per person in 2026. The gift never counts as income, which can also keep you under the Medicare surcharge lines.

Income-based phaseouts

The new $6,000 deduction for people 65 and older, available through 2028, shrinks once income passes $75,000 for single filers or $150,000 for couples. For some retirees, this may mean delaying Roth conversions to take advantage of this new tax benefit.

How much of your Social Security is taxable works on a similar sliding scale. A few thousand dollars of extra income can cost more than it looks. This Social Security "Tax torpedo" can lead to effective taxes rates over 40% for retirees who take only very modest withdrawals.

In practice, look for an advisor who reviews your actual tax return every year, projects several years ahead, and works with your CPA. Tax preparation and tax planning aren't the same thing. Your preparer reports last year. A planner shapes next year.

Good tax planning often moves money out of investment accounts: conversion taxes paid from savings, gifts made straight from an IRA, spending down accounts early to use low tax brackets. A flat fee advisor keeps those recommendations free of any concern about your actions impacting their bottom line.

Where to look

Flat fee advisors are still a small part of the industry, so start where they're concentrated.

• NAPFA (the National Association of Personal Financial Advisors) lists fee-only advisors you can search by location and specialty. Every member is fee-only, but many charge a percentage of assets, so you'll still need to check pricing.
• XY Planning Network requires members to offer planning without an asset minimum, and its search tool lets you filter by how advisors charge.
• Fee-Only Network is another directory limited to fee-only advisors.
• Your CPA. Your tax preparer sees the results of other advisors' work on real returns every spring. Ask whose clients show up with the most thoughtful tax planning.
• A direct online search. Searching "flat fee financial advisor" along with "retirement" or "Roth conversions" online or in AI will surface firms that publish their pricing.

Don't limit yourself to your town. Many flat fee firms work with clients nationwide by video. Just ask whether the advisor knows your state's tax rules, since those affect withdrawal and conversion decisions.

How to check an advisor before you meet

Every registered investment advisor files a public disclosure called Form ADV. You can read it free on the SEC's Investment Adviser Public Disclosure site at adviserinfo.sec.gov.

Search the firm's name and open two documents:

• Form ADV Part 2A, the firm brochure. Go straight to Item 5, "Fees and Compensation." If you see a percentage of assets, asset-based tiers, or commissions, the firm isn't purely flat fee, whatever its website says.
• Form CRS, a short relationship summary written in plain English. It covers fees, conflicts of interest, and any disciplinary history.

While you're there, check whether anyone at the firm is also registered as a broker or licensed to sell insurance. That doesn't automatically rule them out, but it means commissions are possible.

Finally, confirm the advisor acts as a fiduciary, meaning legally required to put your interests first, on all advice and all accounts, all the time.

Questions to ask any advisor

Bring these to your first introductory meeting. A good advisor will answer each one directly.

1. What will I pay each year, in dollars, and what would make that number change? You want a specific figure. If the answer depends on your balance, it isn't a flat fee.
2. Is investment management included, or billed separately? Some firms charge a flat fee for planning and a percentage for investments.
3. Do you receive any compensation from anyone other than me?
4. Do you review my actual tax return every year?
5. How do you decide how much to convert to a Roth each year? Listen for year-by-year projections that weigh Medicare surcharges, Social Security, and your heirs' tax brackets, not a rule of thumb.
6. How do you decide which account I withdraw from? You want a strategy tied to your tax brackets, not a default like taking a little from everything.
7. Will you work with my CPA? Planning and preparation should be connected.
8. Would your pay change if I paid off my mortgage or gave $100,000 to my kids? Under a true flat fee, the answer is no.
9. What isn't included? Comprehensive financial planning should include estate planning review, tax review, property and casualty insurance review, and more. Make sure no services involve add-on fees.
