Calculating Taxes On A Million $ Sale

Understanding Capital Gains Tax on Commercial Real Estate Sales
When you sell a commercial property for a profit, the IRS wants its share. However, unlike selling a stock, calculating the tax bill for real estate is a multi-layered process. It’s not simply a matter of paying a flat percentage on your profit; the “how” and “how long” of your ownership matter immensely.
- Short-term vs. long-term gains matter
- Depreciation recapture increases your tax liability
- High-income surtax (NIIT) may apply
- 1031 Exchange preserves equity
- Effective tax rate can consume a significant portion of profits

Capital Gains Timing
The duration of ownership directly affects your tax rate:
Short-term gains (sold within 1 year) are taxed as ordinary income, potentially up to 37%.
Long-term gains (held over 1 year) enjoy lower rates—typically 15%–20%. Timing your sale can maximize after-tax proceeds.
Depreciation Recapture
This is where commercial real estate investors often get blindsided. Over the years, you likely claimed depreciation deductions to lower your annual tax bill. When you sell, the IRS “recaptures” that benefit. The portion of your gain attributed to those depreciation deductions is not taxed at the 20% capital gains rate; it is taxed at a special Unrecaptured Section 1250 gain rate of 25%.
Net Investment Income Tax (NIIT)
High-income earners generally face an additional hurdle. If your Modified Adjusted Gross Income (MAGI) exceeds $200,000 (single) or $250,000 (married filing jointly), you will likely owe an extra 3.8% Net Investment Income Tax on your capital gains.

Maximizing Net Proceeds When Selling Commercial Property
Many property owners focus only on market timing, but savvy investors also consider tax implications, depreciation recapture, and reinvestment opportunities. Planning ahead ensures you retain the maximum value from a sale.
- Plan Around Capital Gains Timing – Selling at the right time can significantly reduce tax liability.
- Manage Depreciation Recapture Risk – Knowing this in advance allows for strategic sale structuring.
- Leverage 1031 Exchange for Strategic Reinvestment – Roll sale proceeds into new properties to defer taxes entirely.
Conclusion
For a high-earner selling a long-held building, the effective federal tax rate often blends the 20% capital gains rate, the 25% recapture rate, and the 3.8% NIIT. Because this can amount to a significant chunk of your equity, many investors utilize a 1031 Exchange to defer these taxes entirely and roll the full proceeds into a new asset.

Strategic Tax & Exit Planning:
Maximizing Net Proceeds When Selling Commercial Property
Many property owners focus only on market timing, but savvy investors also consider tax implications, depreciation recapture, and reinvestment opportunities. Planning ahead ensures you retain the maximum value from a sale.
1. Plan Around Capital Gains Timing
Selling at the right time can significantly reduce tax liability: Short-term vs. long-term gains affects rates (up to 37% vs. 15–20%). Timing your sale to qualify for long-term capital gains can preserve tens of thousands in net proceeds.
2. Manage Depreciation Recapture Risk
Over the years, claimed depreciation deductions reduce annual taxes—but the IRS recaptures this on sale: Gains from depreciation are taxed at 25%, which can materially reduce your after-tax profit. Knowing this in advance allows for strategic sale structuring or use of offsets.
3. Leverage 1031 Exchange for Strategic Reinvestment
Roll sale proceeds into new properties to defer taxes entirely. Reinvest into stabilized industrial or triple-net (NNN) assets, lower-risk markets like Grand Rapids, or other high-performing properties. Preserves equity and positions your portfolio for long-term growth.
