What Are the 2026 Federal Capital Gains Tax Rates?
Quick Answer: For the 2026 tax year, federal long-term capital gains rates are 0%, 15%, or 20% depending on your taxable income and filing status. Short-term capital gains (assets held less than one year) are taxed as ordinary income at rates up to 37%.
Understanding the 2026 federal capital gains tax structure is essential for Des Moines investors making asset sale decisions. The IRS.gov capital gains guidance clearly distinguishes between long-term and short-term capital gains, with dramatically different tax consequences.
Long-term capital gains—assets held for more than one year—receive preferential tax rates. For the 2026 tax year, the federal long-term capital gains rates remain at 0%, 15%, or 20%. The 0% rate applies to lower-income taxpayers, while the 15% rate covers most middle-income individuals, and the 20% rate applies to high-income earners above specific thresholds.
2026 Federal Long-Term Capital Gains Tax Brackets
The following table shows how 2026 long-term capital gains rates apply based on filing status:
| Filing Status | 0% Rate | 15% Rate | 20% Rate |
|---|---|---|---|
| Single | $0 to $47,025 | $47,025 to $518,900 | Over $518,900 |
| Married Filing Jointly | $0 to $94,050 | $94,050 to $583,750 | Over $583,750 |
| Head of Household | $0 to $62,975 | $62,975 to $551,350 | Over $551,350 |
Short-Term Capital Gains and Holding Period Strategy
Short-term capital gains—from assets held one year or less—receive no preferential treatment under 2026 tax law. Instead, they are taxed as ordinary income at your marginal tax rate, up to 37%. For high-income Des Moines investors, this means short-term gains face nearly double the tax burden of long-term gains.
Pro Tip: When possible, delay selling appreciated assets until you exceed the one-year holding period. The tax savings from moving from short-term (37%) to long-term (15% or 20%) rates can save thousands of dollars on large transactions.
How Are Capital Gains Taxed in Iowa and Des Moines?
Quick Answer: Iowa does not impose a separate capital gains tax. Instead, all capital gains—long-term and short-term—are taxed as ordinary income at Iowa’s progressive income tax rates, which range from 3.63% to 6.50% depending on your bracket.
Unlike some states that tax capital gains differently than wages, Iowa taxes capital gains as ordinary income. This means Des Moines investors face both federal and Iowa state taxation on all gains from asset sales, creating a combined tax burden that can reach 43.5% for high-income earners.
For business owners selling S-Corps, LLCs, or real property near Des Moines, this combined federal-state tax impact significantly affects net proceeds. Strategic planning around entity selection, timing of sales, and installment arrangements becomes critical.
Iowa’s Tax-Efficient Entity Selection
Since Iowa taxes capital gains as ordinary income, entity structuring decisions become even more important. Structuring investments through qualified business entities or holding companies may provide opportunities to minimize combined federal and state tax exposure through strategic basis step-ups or installment sales arrangements.
What Is the Primary Home Capital Gains Exclusion?
Quick Answer: For 2026, primary home sellers can exclude up to $250,000 (single filers) or $500,000 (married filing jointly) of capital gains from federal taxation under IRC Section 121. This exclusion is available once every two years.
The primary residence capital gains exclusion is one of the most valuable tax breaks available to Des Moines homeowners. For 2026, eligible homeowners can completely eliminate federal tax on gains up to $250,000 (single) or $500,000 (married filing jointly). However, this exclusion comes with specific requirements.
Eligibility Requirements for the Primary Home Exclusion
- You must have owned the home for at least 2 of the last 5 years.
- You must have lived in the home as your primary residence for at least 2 of the last 5 years.
- You cannot have used the exclusion on another home in the last 2 years.
- The property must not have been held for business or investment purposes (rental properties don’t qualify).
Did You Know? An estimated 29 million homeowners (34%) could exceed the $250,000 exclusion for single filers, meaning 8 million households may owe federal capital gains tax on home sales above the $500,000 married threshold. Strategic planning is essential if you fall into this category.
What Is the Net Investment Income Tax and How Does It Apply?
Quick Answer: High-income earners over $200,000 (single) or $250,000 (married filing jointly) face an additional 3.8% net investment income tax (NIIT) on capital gains in 2026, potentially pushing combined tax rates to 43.8% before state taxes.
In addition to regular federal income tax on capital gains, high-income Des Moines investors may owe the Net Investment Income Tax (NIIT). This 3.8% tax applies to the lesser of your net investment income or the amount your modified adjusted gross income (MAGI) exceeds certain thresholds.
2026 NIIT Thresholds and Planning Opportunities
For the 2026 tax year, NIIT thresholds are: Singles $200,000, Married Filing Jointly $250,000, Heads of Household $125,000, and Married Filing Separately $125,000. Business owners who can structure income as W-2 wages instead of pass-through capital gains may reduce NIIT exposure through strategic tax planning.

Quick Answer: Real estate investors should consider 1031 exchanges to defer capital gains, installment sales to spread income across years, and strategic property disposition timing to optimize federal and Iowa tax liability.
Real estate investors in Des Moines face unique challenges because rental properties and investment real estate don’t qualify for the primary residence capital gains exclusion. For real estate investors and landlords, alternative strategies become essential to minimize federal and state capital gains taxes.
1031 Exchanges: Deferring Capital Gains Indefinitely
A 1031 exchange allows investors to defer all capital gains tax by exchanging one investment property for another of like-kind. For Des Moines rental property investors, swapping one Des Moines apartment complex for another, or even exchanging it for commercial or agricultural property, can defer gains indefinitely if property exchanges continue.
Key timing rules: You must identify replacement property within 45 days of sale and close within 180 days. Failure to meet these strict deadlines triggers full capital gains taxation.
Installment Sales for Spread Income Recognition
Instead of recognizing all capital gains in one tax year, investors can structure sales using the installment method. This spreads gain recognition across multiple years, potentially keeping you in lower tax brackets. For a Des Moines investor selling a $2 million property with $1 million gain, installment treatment means recognizing $333,000 in gain across three years instead of $1 million in year one.
How Can You Use Tax-Loss Harvesting to Reduce Capital Gains?
Quick Answer: Tax-loss harvesting allows you to sell securities with losses to offset capital gains dollar-for-dollar, with up to $3,000 of excess losses reducing ordinary income. Remaining losses carry forward indefinitely.
For investment portfolio managers, one of the most powerful strategies is tax-loss harvesting. When you sell securities at a loss, those losses can offset capital gains from other sales, reducing or eliminating your total capital gains tax liability.
The Wash Sale Rule and Strategic Rebalancing
When harvesting losses, the wash-sale rule prohibits repurchasing substantially identical securities within 30 days before or after the loss sale. However, you can purchase similar (but not identical) securities immediately—for example, selling Stock A and buying a different company in the same sector. This allows you to maintain portfolio exposure while locking in losses and avoiding the wash-sale trap.
Uncle Kam in Action: Des Moines Real Estate Success Story
Sarah Mitchell, a Des Moines real estate investor, owned three rental properties acquired over 12 years. In 2026, she decided to consolidate her portfolio by selling two properties to fund acquisition of a larger commercial complex. Without strategic planning, her capital gains on the two properties would have totaled approximately $850,000, creating federal taxes of roughly $170,000 (at 20% plus NIIT) plus Iowa state taxes of approximately $45,000.
Sarah worked with Uncle Kam tax strategists who implemented a 1031 exchange strategy. Instead of receiving cash proceeds that would trigger immediate capital gains, she exchanged the two properties into a single larger commercial property in Des Moines. This deferred all $850,000 in capital gains, eliminating the $215,000 combined federal-state tax liability in year one.
Additional optimizations included timing her third property’s sale into 2027 to spread remaining gains across two years, and repositioning a $200,000 portfolio gain loss against $300,000 in investment gains through strategic tax-loss harvesting. Net result: Sarah reduced her 2026 capital gains tax liability from $215,000 to $0, with remaining gains deferred to future years.

Frequently Asked Questions
What is the difference between short-term and long-term capital gains for 2026?
Short-term capital gains come from assets held one year or less and are taxed at ordinary income rates up to 37%. Long-term capital gains (held over one year) receive preferential tax treatment at 0%, 15%, or 20% rates. For Des Moines investors, this can mean a difference of 17-37 percentage points in tax liability on the same dollar of gain.
Does Iowa have a separate capital gains tax?
No. Iowa taxes all capital gains as ordinary income at state rates ranging from 3.63% to 6.50%. This means Des Moines investors face combined federal and state taxation on capital gains without any preferential state treatment. A $100,000 long-term capital gain faces 15% federal tax plus up to 6.5% Iowa tax for a combined 21.5% burden.
Can I exclude capital gains from selling my Des Moines home?
Yes, under IRC Section 121, you can exclude up to $250,000 (single) or $500,000 (married filing jointly) from federal taxation. This applies if you owned and lived in the home for at least 2 of the last 5 years. Rental properties and investment homes do not qualify for this exclusion.
What is the 3.8% net investment income tax?
The Net Investment Income Tax (NIIT) applies to high-income individuals with MAGI over $200,000 (single) or $250,000 (MFJ). It’s an additional 3.8% tax on the lesser of net investment income or excess MAGI. For Des Moines investors selling property, this can add nearly 4 percentage points to federal capital gains rates.
How does a 1031 exchange work for Des Moines real estate investors?
A 1031 exchange allows you to defer capital gains tax by exchanging one investment property for another like-kind property. For Des Moines investors, this means selling a rental property and acquiring a replacement property without triggering capital gains tax, as long as you identify the replacement within 45 days and close within 180 days. The exchange can continue indefinitely, deferring gains until you finally sell without doing another exchange.
Can I use tax-loss harvesting to offset capital gains?
Yes. Capital losses can offset capital gains dollar-for-dollar. If losses exceed gains, you can deduct up to $3,000 against ordinary income in the current year, with remaining losses carried forward indefinitely to future years. The wash-sale rule prohibits repurchasing substantially identical securities within 30 days before or after the loss sale.
What is the deadline for reporting capital gains on my 2026 return?
Capital gains from 2026 sales must be reported on your 2026 Form 1040 federal return filed by April 15, 2027 (or extended to October 15, 2027 with an extension). Form Schedule D reports all long-term and short-term capital gains and losses. Iowa tax returns are generally due on the same dates as federal returns.
Should I time my asset sales based on capital gains tax brackets?
Absolutely. Strategic timing can determine whether long-term capital gains are taxed at 0%, 15%, or 20%. A Des Moines investor with $50,000 in other income plus $100,000 in capital gains might reduce the rate on the entire gain from 20% to 15% by timing the sale into the next year. Consulting with a tax strategist before major sales is critical.
