Why is Tax Planning Important?

Tax planning in retirement is important because you are no longer accumulating … you are now in the distribution phase … or “paying yourself.”

There are tax-efficient ways to do this. There are even some pitfalls to watch out for.

Introduction: A Different Lens on Retirement Income

At our firm, one of our core values is Commitment to Financial Planning. That means going beyond investment returns and focusing on after-tax outcomes.

In retirement, taxes don’t disappear; they become more complex.

The real opportunity lies in coordinating income sources, timing decisions, and understanding how different buckets are taxed.

Today, we’re going to explore:

  • Why dividend-heavy strategies can backfire

  • The power of capital gains brackets

  • Roth conversion opportunities (and pitfalls)

  • How Social Security taxation quietly increases your effective tax rate

  • Why product decisions, like annuities, can limit flexibility

1. Not All “Income” Is Created Equal

One of the biggest misconceptions we see is the idea that dividends are inherently tax-efficient.

While qualified dividends can receive favorable tax treatment, they still:

  • Add to your total taxable income

  • Interact with other income sources (Social Security, IRA withdrawals, new OBBBA enhanced senior deduction thresholds)

  • Can push you into higher tax brackets or increase Social Security taxation

Meanwhile, other strategies (like capital gain realization) can be more controllable and tax-efficient.

The Key Distinction:

  • Ordinary income: IRA withdrawals, annuities, and non-qualified dividends could be taxed up to 37%

  • Capital gains / qualified dividends: taxed at 0%, 15%, or 20% depending on income

Bottom line … tax treatment matters.

2. Capital Gains Brackets: A Huge Planning Opportunity

The tax code gives retirees a powerful planning window through preferential capital gains rates.

2026 Federal Capital Gains Thresholds (Taxable Income)

Married Filing Jointly:

  • 0% rate: up to $98,900

  • 15% rate: $98,900 to $613,700

Single filers:

  • 0% rate: up to $49,450

  • 15% rate: $49,450 to $545,500

These brackets sit on top of ordinary income.

Important nuance:

Your ordinary income fills the bracket first, and capital gains stack on top.

Planning opportunities:

  • Tax-gain harvesting at 0%

  • Coordinating withdrawals across pre-tax, after-tax, and Roth accounts

  • Avoiding unnecessary dividend income that fills these brackets

3. Why Dividend Investing Can Actually Hurt You

Dividend investing is often marketed as “safe income,” but from a planning perspective, it can reduce flexibility.

The problem:

Dividends are:

  • Forced income

  • Taxable every year

  • Not easily turned off in high-income years

Compare that to:

  • Selling appreciated assets (you control timing)

  • Using Roth funds (tax-free)

  • Managing bracket exposure

Real planning issue:

Dividends can:

  • Push you out of the 0% capital gains bracket

  • Increase Social Security taxation

  • Reduce your ability to execute Roth conversions efficiently

This is where our company value of Education and Personal Growth matters. We want clients to understand that “income” is not always optimal.

4. Roth Conversions: Filling the 12% Bracket Strategically

One of the most valuable retirement strategies is Roth conversion planning.

2026 Ordinary Income Anchors (MFJ):

  • 12% bracket top: $100,800 taxable income

This creates a window to:

  • Convert IRA assets at relatively low rates

  • Reduce future RMDs

  • Improve long-term tax diversification

Enhanced Senior Deduction Opportunity

OBBBA adds:

  • $6,000 per person age 65+ (up to $12,000 MFJ)

  • Begins phase-out at $150,000 MAGI (MFJ)

Planning opportunity:

  • Convert income up to that phase-out threshold

  • Capture deductions & low brackets simultaneously

5. The Hidden Trap: Effective Tax Rates & Social Security

This is where planning becomes critical.

Social Security taxation creates a “tax torpedo” effect:

  • 0% taxable at low income

  • Up to 50% taxable

  • Up to 85% taxable once thresholds are exceeded

2026 Key Thresholds (MFJ):

  • $32,000 … taxation begins

  • $32,000–$44,000: up to 50% taxable

  • Over $44,000: up to 85% taxable

These thresholds are based on the provisional income calculation for Social Security.

Why this matters:

Every additional $1 of income can:

  • Trigger more SS becoming taxable

  • Create an effective marginal rate far higher than 12%

Example: A “12% bracket” Roth conversion may actually feel like:

  • 18%

  • 22%

  • Or higher after SS inclusion

It’s not about your marginal bracket. It’s about your effective rate on the next dollar.

This is where our other company value, Teamwork and Collaboration, matters. The analysis must be coordinated across:

  • Tax projections

  • Retirement income sources

  • Timing of Social Security

For many retirees, the most attractive window for Roth conversions is the period after you retire but before you begin Social Security. During those years, income is often temporarily lower and easier to control. Once Social Security begins, the analysis becomes more complex, and it is important to evaluate whether conversions still make sense based on your effective tax rate.

6. Annuities & Their Flexibility Trade-Off

Annuities can serve a purpose, but they come with a planning cost.

The issue:

  • Income is typically fully taxable as ordinary income

  • Payments are often fixed and inflexible

  • Little control over timing

Planning consequences:

  • Fills up lower tax brackets

  • Reduces room for Roth conversions

  • Can increase Social Security taxation

  • Amplifies the widow’s penalty

Widow’s penalty risk:

  • Surviving spouse moves to single brackets

  • Same income, but at higher rates

  • Fixed annuity income leaves no adjustment flexibility

Flexibility is a tax asset.

7. Bringing It Back to CENTER

This is where our team’s values come to life:

  • Commitment: We go beyond surface-level strategies

  • Education: Helping clients understand tax mechanics

  • Nice & Kind: Explaining complex topics simply

  • Teamwork: Coordinating tax, investment, and retirement plans

  • Energy: Proactively identifying opportunities

  • Real: Honest conversations about trade-offs

Conclusion: Tax Planning Is the Strategy

Retirement is not just about generating income; it’s about controlling how that income shows up on your tax return.

The difference between a good plan and a great plan often comes down to:

  • Timing

  • Tax characterization

  • Coordination across income sources

Every decision … income, investments, products … should be evaluated through a tax lens.

Unless certain criteria are met, Roth IRA owners must be 59½ or older and have held the IRA for five years before tax-free withdrawals are permitted. Additionally, each converted amount may be subject to its own five-year holding period. Converting a traditional IRA into a Roth IRA has tax implications. Investors should consult a tax advisor before deciding to do a conversion.

Investing involves risk and you may incur a profit or loss regardless of strategy selected, including diversification and asset allocation.
