Key Takeaways
- The Augusta Rule lets clients rent a home 14 days tax-free.
- Section 280A(g) governs the personal residence 14-day exclusion.
- The STR strategy needs an average stay of seven days or less.
- Material participation unlocks losses against W-2 and business income.
- The 2025 tax law made 100% bonus depreciation permanent for 2026.
What Is the 14-Day Rental Rule?
Quick Answer: The 14-day rental rule requirements come from Section 280A. They control when rental income is tax-free and when losses count.
The phrase “14-day rental rule” actually covers two separate tax concepts. Both live inside Section 280A of the tax code. However, they work in very different ways. The first is the Augusta Rule, which makes short rental income tax-free. The second involves short-term rentals and the material participation test.
As a tax pro, you must know both cold. Clients often mix them up. Therefore, clear guidance builds trust and shows your value. Moreover, these strategies open the door to high-ticket ongoing tax advisory relationships.
The Two Faces of the 14-Day Rule
First, the Augusta Rule uses a 14-day rental limit on a personal home. Rent it 14 days or fewer, and the income is tax-free. Second, the STR rule uses a different threshold. There, the average guest stay must be seven days or less.
- Augusta Rule: rent your home 14 days or less per year.
- STR strategy: average guest stay of seven days or less.
- Both rules trace back to Section 280A of the code.
Why This Matters for Your Clients
Real estate remains one of the best tax shelters in 2026. Consequently, business owners and high earners want in. Many of your clients already own a second home. Others plan to buy soon. In both cases, the 14-day rental rule requirements shape their tax outcome. As a trusted advisor to real estate investors, you guide that decision.
Pro Tip: Never assume a client knows the difference. Always confirm which rule fits their goal first.
How Does the Augusta Rule Work?
Quick Answer: Section 280A(g) lets clients rent a home 14 days or less. That rental income stays completely tax-free.
The Augusta Rule got its name from the Masters golf tournament. Homeowners there rent to visitors during the event. Under IRS Publication 527, a personal residence rented 14 days or fewer creates no taxable income. In other words, the client keeps every dollar tax-free.
This rule works best for business owners. For example, an S corp owner can rent their home to their own company. The company then holds meetings there. As a result, the business gets a deduction. Meanwhile, the owner reports zero income. This entity-aware layering is exactly where advisory value shines.
The Core Augusta Rule Requirements
To qualify, clients must follow strict steps. Otherwise, the deduction fails an audit. Documentation is everything here.
- Rent the home 14 days or less each year.
- Use the property as a personal residence.
- Charge a fair market rental rate.
- Keep written rental agreements and meeting notes.
- Document comparable rates from local venues.
A Simple Augusta Rule Example
Suppose a client owns an S corp. They rent their home to the business for 12 days. Local venues charge $1,500 per day. Therefore, the business pays $18,000 in rent. The company deducts $18,000. Meanwhile, the owner reports $0 in income. At a 37% bracket, that saves roughly $6,660 in tax. This strategy pairs well with proactive year-round tax planning.
Pro Tip: Have clients get three venue quotes. This proves the rent is fair and audit-proof.
What Are the STR 14-Day Rental Rule Requirements?
Quick Answer: A short-term rental with an average stay of seven days or less avoids passive rules. Then material participation unlocks big losses.
The short-term rental strategy is the second face of the 14-day rental rule requirements. Here, the property is not passive. Instead, it counts as an active business. As a result, losses can offset W-2 and business income. This is why high earners rush to buy short-term rentals in 2026.
The key is the average stay test. If the average guest stay is seven days or less, the rental escapes the passive loss rules. Furthermore, the 2025 tax law made 100% bonus depreciation permanent. Consequently, first-year deductions can be huge. Business owners can review options on our business owner tax page.
The Material Participation Test
Passing the average stay test is only step one. Next, the client must materially participate. The IRS lists several ways to meet this bar. Two matter most for short-term rentals.
- Spend 500 or more hours on the rental activity.
- Spend 100+ hours and more than anyone else.
- Do substantially all the work on the property.
Married couples have an edge here. Both spouses’ hours count toward the test. Therefore, a stay-at-home spouse can run the rental. See the IRS passive activity rules in Publication 925 for full detail.
Watch Out for Local Rules
Federal tax rules are only half the story. Cities keep tightening short-term rental laws in 2026. Salt Lake City, for example, now requires business licenses. Rentals must book at least two nights. Also, they cannot exceed 200 nights per year. The annual license fee is $198, plus $342 per unit. These local caps can affect the average stay math.
Did You Know? A two-night minimum booking rule can still fit the seven-day average test easily.
Executing strategies in isolation is risky. Uncle Kam uses the MERNA framework to evaluate the whole picture. Our entity-aware tax planning software models 1040s, 1120-S returns, and K-1s at once. As a result, you avoid strategy conflicts and audit traps.
How Much Can Clients Save With These Rules?
Quick Answer: A single short-term rental can cut a client’s tax bill by tens of thousands. Cost segregation drives the savings.
The savings come from bonus depreciation. First, the client orders a cost segregation study. That study splits the home into parts. Roughly a third of the value often qualifies for fast depreciation. Then bonus depreciation lets them claim it in year one.
A Real Depreciation Example
Take a $450,000 home on a $50,000 lot. A cost segregation study might find $150,000 in fast depreciation. At the top bracket, that reduces the tax bill by about $55,000. In effect, the government funds part of the down payment. Explore related tools in our suite of tax calculators.
| Item | Amount (2026) |
|---|---|
| Home purchase price | $450,000 |
| Cost seg depreciation found | $150,000 |
| Client marginal bracket | 37% |
| First-year tax savings | ~$55,000 |
Comparing the Two Strategies
Each rule serves a different client. The Augusta Rule fits business owners with a home. The STR strategy fits investors with capital. This table shows the key differences clearly.
| Feature | Augusta Rule | STR Strategy |
|---|---|---|
| Day threshold | 14 days or less rented | 7-day average stay |
| Main benefit | Tax-free income | Loss deductions |
| Best client fit | Business owners | Active investors |

What Mistakes Should You Avoid?
Quick Answer: The biggest mistakes are poor records and blown day counts. Both can wipe out the tax benefit fast.
These strategies work only with clean execution. Sloppy tracking invites IRS pushback. Therefore, you must set clear systems for every client. Good documentation is your best defense.
Common Augusta Rule Errors
- Renting more than 14 days by accident.
- Charging rent above fair market value.
- Skipping written meeting minutes and agreements.
- Failing to issue a Form 1099 when required.
Common STR Strategy Errors
The STR strategy fails most often on hours. Clients forget to track time carefully. Also, they outsource too much work. Both problems can break material participation. Learn more about smart entity structuring to protect these deductions.
- Letting the average stay exceed seven days.
- Using a property manager for all tasks.
- Keeping no time log for hours worked.
- Ignoring recapture tax at future sale.
Pro Tip: Give clients a shared time-tracking log. Review it every quarter, not just at tax time.
Remember, depreciation is a deferral, not forgiveness. When the client sells, recapture tax applies. Many investors plan a 1031 exchange to defer that hit. Others plan to hold the property for life.
Uncle Kam in Action: Cabin Investor Cuts a $70K Tax Bill
Client Snapshot: A married surgeon and her spouse came to a tax pro using Uncle Kam. They wanted to lower a large W-2 tax bill for 2026.
Financial Profile: Combined household income sat near $600,000. They had $130,000 in cash to invest. Also, they faced a projected federal tax bill above $150,000.
The Challenge: The couple owned no rentals yet. However, they wanted real estate to build wealth and cut taxes. They did not understand the 14-day rental rule requirements. As a result, they nearly bought a long-term rental instead. That choice would have trapped the losses as passive.
The Uncle Kam Solution: The advisor mapped the STR strategy first. They bought a $460,000 mountain cabin near a ski resort. The average guest stay stayed under seven days. Meanwhile, the stay-at-home spouse logged over 120 hours managing the rental. Therefore, the couple met material participation.
Next, the advisor ordered a cost segregation study. It found $155,000 in fast depreciation. With permanent 100% bonus depreciation, they claimed it in year one. The advisor also tracked every hour in a shared log. Consequently, the deduction stood on solid ground.
The Results: The $155,000 loss offset their high W-2 income. As a result, the couple saved about $57,000 in federal tax for 2026. They paid the tax pro a $4,500 planning fee. That works out to a first-year ROI of more than 12 times. See more wins on our client results page.
