📉 Capital Loss vs. Ordinary Loss: A Tax Concept I’m Learning in CFP Prep (Through a Nursing Lens)

One thing I’m deep in right now as part of my Certified Financial Planner® prep is taxes specifically how different types of losses are treated very differently by the IRS.

On paper, a loss is a loss.

In real life (and on your tax return), that’s not how it works.

Two terms that come up a lot are capital losses and ordinary losses, and understanding the difference matters more than most people realize.

First: what’s a capital loss?

A capital loss happens when you sell an investment (like stocks, ETFs, or mutual funds) for less than what you paid for it.

Key points:

• Capital losses are primarily used to offset capital gains

• If losses exceed gains, you can deduct up to $3,000 per year against ordinary income

• Any unused losses can be carried forward to future years

Capital losses are helpful but they’re limited in how they can be used.

What’s an ordinary loss?

An ordinary loss is tied to regular income or business activity, not investments.

Examples include:

• certain business losses

• unreimbursed expenses in qualifying situations

• losses connected to income that would normally be taxed at ordinary rates

Ordinary losses generally offset ordinary income dollar for dollar, without the same $3,000 annual cap that applies to capital losses.

From a tax perspective, ordinary losses tend to be more immediately powerful.

A nursing analogy (because this is where it clicked for me)...

Here’s how I’ve been thinking about it.

Imagine two nurses working the same week.

Nurse A:
Picks up an extra shift, but gets floated to a lower-acuity unit and earns less than expected. That’s frustrating but it still fits within the normal structure of how pay works.

That’s like a capital loss.
Useful, but with rules and limits.

Nurse B:
Shows up for a scheduled shift, but payroll messes up and doesn’t pay them at all or pays them incorrectly.

That’s an ordinary loss.
It directly affects core income and gets addressed differently.

Same frustration.

Very different implications.

Why this distinction matters in real life

A common misconception I see is:
“Losses are losses; they’ll all reduce my taxes the same way.”

But:

• Selling investments at a loss doesn’t automatically reduce your tax bill meaningfully

• Capital losses don’t offset ordinary income beyond a point

• Timing, type of income, and category matter

This is why tax strategy isn’t just about what happened, but how it’s classified.

What I’m taking away as I study this

What’s standing out to me most in CFP prep is how much tax planning is about categories, not effort.

You can do something that feels financially painful and still get limited tax relief; simply because of how the system is structured.

That’s not intuitive.
And it’s why understanding these distinctions helps you make decisions with eyes open, not after the fact.

A NurseMoneyDate® reflection this week

You don’t need to memorize tax rules to benefit from this.

A helpful question is:

“If something goes wrong financially, do I know whether it affects my ordinary income or my investments and does that change how I’d plan for it?”

Awareness alone improves decision-making.

And as always, this is about understanding the system you’re operating inside, not trying to game it.
