When Should You Start Social Security? A DFW Advisor’s Honest Take

The “right” age to claim Social Security isn’t 62, 67, or 70. It depends on YOUR numbers.

I hear this question more than almost any other: When should I start taking Social Security? And the answer is almost never as simple as the internet makes it seem. There’s no universal best age. There’s only the best age for you — and that requires running the numbers specific to your situation.

Here’s what most people get wrong, and what I walk my clients through before they make this six-figure decision.

Why the “Break-Even” Calculation Is Misleading

You’ve probably seen the math. If you delay from 62 to 67, you give up five years of payments, but you get a higher monthly amount forever. At some point, the total from the higher payment catches up. That’s the “break-even age.”

The problem is this analysis assumes you know when you’ll die. You don’t.

Social Security isn’t a bet on longevity. It’s insurance against living longer than your money lasts. When you frame it as a gamble, you’re thinking about it wrong. Insurance protects the downside. A break-even analysis treats it like a wager. Those are two completely different frameworks, and one of them leads to much better decisions.

How Your Spouse’s Benefit Changes the Equation

Here’s where it gets personal. Your Social Security decision doesn’t just affect you — it affects your spouse.

When one spouse passes away, the surviving spouse keeps the higher of the two benefits and loses the lower one. That means the higher earner’s filing decision essentially determines the survivor benefit for the rest of their life.

If the higher earner files early and takes a reduced benefit, the surviving spouse could be locked into that reduced amount for decades. One decision, two lives. That’s worth slowing down and modeling carefully.

The Tax Torpedo Most People Don’t See Coming

Most people assume Social Security is tax-free. It’s not.

Depending on your total income in retirement — which includes withdrawals from IRAs, 401(k)s, pensions, and even investment income — up to 85% of your Social Security benefits can be subject to federal income tax. This is what planners call the “tax torpedo,” and it catches people off guard every year.

The timing of when you file for Social Security directly affects your taxable income in retirement. File at the wrong time relative to your other income sources, and you could push yourself into a higher tax bracket or trigger Medicare surcharges (IRMAA) you never expected.

Living in Texas helps — there’s no state income tax. But federal taxes still apply, and the interaction between Social Security, RMDs, and investment income is where the real tax planning happens.

Real Scenarios from My Practice

I’ve seen clients where filing at 62 was clearly the right move — they had a pension covering their fixed expenses, no surviving spouse concerns, and health considerations that made an early claim practical.

I’ve seen others where waiting until 70 saved their spouse over $200,000 in lifetime income. Same question, completely different answers.

The difference wasn’t luck. It was running the numbers. Every scenario I model accounts for federal taxes, Medicare premiums, spousal benefits, other income sources, and longevity assumptions. Without that full picture, you’re guessing — and this is one decision you can’t undo.

How to Model Your Own Decision

If you’re approaching this decision, here’s what I’d suggest. Don’t start with a rule of thumb. Start with your actual numbers.

Know your full retirement age benefit amount. Know your spouse’s benefit. Understand how your other income sources interact with Social Security taxation. Factor in Medicare premiums that change based on income. And most importantly, think about this not as a break-even problem but as an income planning problem.

What does your retirement income look like at 62? At 67? At 70? Which scenario gives you the most stable, tax-efficient income for the longest period of time?

That’s the analysis worth doing. And if it feels complicated, that’s because it is. This isn’t a decision to make over lunch. It’s a decision that shapes the next 20 to 30 years of your financial life.
