Do I Have to Pay Taxes If I Sell My Mortgage Note?

When you sell a mortgage note, the IRS treats it the same way it treats the sale of any asset. You owe capital gains tax on the difference between your “basis” (what the note cost you) and the sale price.

For most private note holders, the note was created when you sold a property and carried the financing. In that case, your basis is typically the adjusted cost basis of the property at the time of sale, meaning what you originally paid for it, plus improvements, minus depreciation.

The gain, the difference between that basis and what the note buyer pays you, is subject to capital gains tax.

This isn't unique to notes. Selling stocks, real estate, or any other appreciated asset triggers the same type of tax. But with notes, many sellers don't expect it, and it can significantly reduce what they actually walk away with.

The tax rate depends on how long you've held the asset and your income level.

Federal long-term capital gains rates (for assets held longer than one year) currently range from 0% to 20%, depending on your taxable income. Most note holders fall in the 15% bracket, though higher earners may owe 20%.

State taxes may apply on top of federal. Some states, like Florida and Texas, have no state income tax, which is one advantage for note holders in those states. Others, like California, can add 10% or more.

Here's what the math looks like in practice:

Imagine you hold a $500,000 mortgage note. You originally sold the property and carried the financing, and your adjusted basis in the note is roughly $200,000.

A note buyer offers $400,000 (after a 20% market discount). Your taxable gain is $200,000 ($400,000 sale price minus $200,000 basis).

At a 15% long-term capital gains rate, that's $30,000 in federal taxes, on top of the $100,000 you already lost to the buyer's discount.

The combined impact: you started with a $500,000 note and walk away with roughly $370,000. That's a 26% loss just to access your own money.

If you sell only a portion of your note (what's called a “partial”), you still owe proportional taxes on the proceeds you receive. There's no way to sell and avoid the tax entirely.

This is a common question: “Can I do a 1031 exchange with my note?”

Section 1031 of the Internal Revenue Code allows you to defer capital gains taxes when you sell one investment property and buy another “like-kind” property. It's widely used in real estate.

However, mortgage notes are generally not considered “like-kind” to real property. A 1031 exchange is designed for swapping real estate: land for land, building for building. Swapping a note for a property (or vice versa) doesn't typically qualify.

There are some niche arguments around certain note structures, and the law has grey areas. But in practice, relying on a 1031 exchange for a note sale is risky and not widely accepted by tax professionals.

The bottom line: don't plan your strategy around a 1031 exchange for your note without getting specific advice from a qualified CPA.

Here's where it gets interesting, and where many note holders find a better path.

The IRS distinguishes between selling an asset and borrowing against an asset. When you sell, you realize a gain, and that gain is taxable. When you borrow, no gain is realized, so there's no tax.

This is the same principle that applies to:

• A home equity line of credit (you're not selling your house, you're borrowing against it)
• A margin loan on stocks (you're not selling your shares, you're borrowing against them)
• An auto title loan (you're not selling your car, you're borrowing against it)

None of those trigger a tax event. Neither does borrowing against a mortgage note.

This approach, using your note as collateral for a loan rather than selling it, is called hypothecation. You keep full ownership of the note, you keep collecting your monthly payments, and the IRS doesn't consider it a taxable event.

We cover this in detail in our guide on note hypothecation.
