The Augusta Rule: 14 Days of Tax-Free Home Rental for Bay Area Business Owners

If you own a business in the Bay Area and you host any kind of meeting, retreat, or working session at your house, there is a tax provision sitting right in the Internal Revenue Code that most owners have never heard of. It is called the Augusta Rule, codified at IRC Section 280A(g). It allows you to rent your personal residence to your own business for up to 14 days per year at a fair market rate, take the rent as a deductible business expense, and exclude every dollar of the rental income from your personal tax return.

For a Palo Alto founder paying combined federal and California marginal rates near 46%, fourteen days at $3,500 a day moves about $49,000 of cash from the business to the owner with roughly $23,000 of tax savings. The strategy is legal, the statute is short, and the IRS has been losing audit cases on it for decades when taxpayers do the documentation right. They also win audits constantly when taxpayers do not.

This guide walks through what the Augusta Rule actually says, the math for a typical Bay Area owner, the documentation that survives an exam, and the half-dozen ways founders blow it up. We work with owners on this planning regularly through our entity tax practice at Silicon Valley Tax.

What the Augusta Rule Actually Says

IRC §280A(g) reads simply. If a dwelling unit is used by a taxpayer as a residence during the taxable year, and that dwelling is actually rented for fewer than 15 days during the year, then no deductions are allowed and no rental income is included in gross income. In other words, the rent disappears from the homeowner's 1040. It is not deferred, not phased out at higher incomes, not preference income for AMT. It is simply excluded.

The provision exists because of Augusta, Georgia. Each April during the Masters tournament, homeowners around Augusta National rent their houses to corporate sponsors, players, and patrons for $10,000 to $50,000 a week. By the 1970s the IRS was spending more on auditing one-week rentals than it was collecting. Congress chose the simple fix: under 15 days, do not report it at all.

The statute does not limit who the renter must be. A homeowner can rent to a stranger, a family member, or a business that the homeowner controls. As long as the rental is for fewer than 15 days, the rent is real, and the dwelling qualifies as a residence under §280A(d), the exclusion applies.

How Small Business Owners Use It

The play is straightforward. The owner of a closely held business (S-corp, LLC, or sole proprietorship that files Schedule C) holds a legitimate business event at the personal residence and has the business pay the homeowner rent at a fair market rate. The business deducts the rent as an ordinary and necessary expense under IRC §162. The homeowner excludes the income on the personal return under §280A(g).

Legitimate business uses include:

• Board meetings. Quarterly board meetings of an S-corp or LLC, with minutes, agenda, and attendees recorded.
• Annual planning offsites. Multi-day strategy or budget sessions for the leadership team.
• Training sessions. Sales training, product training, or onboarding for distributed teams flying in.
• Client dinners and events. Hosted client appreciation events with documented business purpose.
• Investor or partner meetings. Pitch sessions, partnership negotiations, or LP updates for fund managers.

The business purpose has to be real. A "board meeting" with no minutes, no agenda, and the owner as the only attendee is not a board meeting. It is a sham and the IRS treats it as one.

The Math for a Bay Area Owner

Bay Area private event rentals run from roughly $1,500 a day for a modest home in a suburban neighborhood to $5,000 a day or more for a larger home in Atherton, Los Altos Hills, or Palo Alto. Most Silicon Valley owners who plan well land somewhere in the $2,500 to $4,000 a day range with comparables to back it up.

At fourteen days a year, a defensible rate produces meaningful cash:

Daily Rate	14 Days Total	Federal Tax Saved (37%)	California Tax Saved (9.3%)	Combined Savings
$1,500	$21,000	$7,770	$1,953	$9,723
$2,500	$35,000	$12,950	$3,255	$16,205
$3,500	$49,000	$18,130	$4,557	$22,687
$5,000	$70,000	$25,900	$6,510	$32,410

The table uses California's 9.3% mid-bracket rate for illustration. Bay Area owners at the 12.3% bracket (single income above ~$721K, MFJ above ~$1.44M) or the 13.3% top bracket (single above $1M) see proportionally higher state-tax savings, often pushing combined savings past $30,000 at $3,500/day.

For S-corp owners the math is even more attractive than the table suggests. The rent reduces business income that would otherwise pass through to a Schedule K-1, so the deduction lands at the owner's full marginal rate plus any state tax. The income would have hit at the same marginal rate. The net is a clean shift of cash from a taxable bucket to a tax-free one.

For C-corp owners the calculation is different. The rent deduction reduces corporate income taxed at 21% federal plus 8.84% California. That is still positive, but the savings per dollar are smaller than for pass-through entities.

Documentation Requirements That Survive Audit

This is where the rule wins or loses on examination. The IRS does not have to prove the rental was a sham. It only has to find the documentation thin enough to disallow the deduction. Five categories of paperwork matter, and we recommend every one of them:

1. A written rental agreement. Signed before the rental, between the homeowner as lessor and the business entity as lessee, specifying dates, daily rate, purpose, and the property address. SVT does not draft contracts. A real estate attorney should write the rental agreement. We handle the tax reporting and the documentation file.
2. Comparable rental rate documentation. At least three written quotes from comparable Bay Area event-rental sources for a similar property. Hotel meeting rooms, private estate rental platforms (Peerspace, Splacer, Giggster for the property type), and event venues all work. Vacation rental rates (Airbnb, Vrbo) generally do not, because the use case is different. The point is that an arm's-length business would have paid roughly the rate you charged.
3. Business purpose documentation per rental. Meeting agenda, list of attendees, minutes or notes, and any presentation materials. For board meetings, formal board minutes signed by all directors. The single most common audit loss is "yes there was a meeting" with nothing on paper to prove it.
4. Actual payment from the business to the homeowner. A check or ACH from the business bank account to the homeowner's personal account, posted close to the event date. Not a year-end lump sum journal entry. If total rental payments to the homeowner exceed $600 for the year, the business issues a Form 1099-MISC (box 1, rents) to the owner. The owner reports the 1099-MISC income on Schedule E and immediately excludes it on the same line with a §280A(g) notation, so the net line-item effect is zero.
5. A calendar of rental days. A simple log of every date the home was rented to the business, with cumulative day count. The whole strategy collapses at day 15.

This documentation file should live with the business records, not in a shoebox. We help clients build the template once, then maintain it each year as part of the year-end close.

What "14 Days" Actually Means

The 14-day count is calendar days of rental, not business days. Two consecutive seven-day retreats count as 14 days. A Friday-through-Sunday weekend counts as three days. If the company holds a multi-day offsite that spills into a 15th day, the entire §280A(g) exclusion fails for the year. The IRS does not pro-rate. You owe tax on every dollar of rental income, and the property potentially falls under the rental-property rules in §280A and Schedule E.

Plan for fourteen and stop. Track the count quarterly. If a planned event would push the year over, move it off-site (hotel, coworking, restaurant) and protect the rest of the year.

One nuance: a "rental day" requires the property to be actually used and paid for as a rental. Days the homeowner is at the property but no business event is occurring do not count toward the 14. The clock only runs on days the business uses the space and pays for it.

Audit Risk Patterns

The IRS has been targeting Augusta Rule deductions in recent years, particularly for high-income S-corp owners. The patterns that trigger scrutiny:

• Round-number annual rent. Exactly $49,000 every year, paid in one December check, with no event-level breakdown. Looks like a year-end tax-planning entry, not a real rental.
• Single annual lump payment. One transfer for all fourteen days instead of payment per event. Real arm's-length rentals pay close to the event date.
• Day rates above $5,000 with no comparable documentation. The rate has to track local market evidence. A $10,000 a day rate in San Jose without solid comparables is a flashing light.
• Related-party at a sham rate. A $50 a day rate to undercount taxable income on the business side, or a $20,000 a day rate to overpay the owner, both fail the arm's-length test. Stay in the band the comparables support.
• No documented business purpose. "Board meeting" with no minutes, no agenda, and the sole shareholder as the only attendee. Tax court has disallowed dozens of cases on exactly this fact pattern.
• Spillover beyond 14 days. Even a single 15th day collapses the exclusion. The IRS finds these in calendar reviews.

Properly documented Augusta Rule deductions hold up. The published case law (notably Sinopoli v. Commissioner, T.C. Memo. 2023-105) is consistent: when the meetings are real, the rate is defensible, and the paperwork is in place, the deduction stands. When any of those three legs is weak, it falls.

Worked Example: Founder of a Consulting LLC

A San Jose founder runs a consulting LLC that has elected S-corp tax treatment. She wants to use the Augusta Rule for 2026. Her draft plan:

• Four quarterly all-hands meetings at her home, two days each at $2,500 per day = $20,000
• Two client appreciation dinners, one day each at $5,000 per event = $10,000
• One week-long executive offsite, seven days at $3,500 per day = $24,500
• Total: 17 days, $54,500

The plan fails immediately because 17 days exceeds the 14-day ceiling. Scaling back to fit the rule:

• Four quarterly all-hands, one day each at $2,500 = $10,000 (4 days)
• One executive offsite, three days at $3,500 = $10,500 (3 days)
• Seven additional event days reserved for ad-hoc strategy sessions, training, or client meetings at an average $3,500 per day = $24,500 (7 days)
• Total: 14 days, $45,000

$45,000 of rent excluded from her personal return under §280A(g). The S-corp deducts $45,000 against ordinary business income. At a combined 46% marginal rate her federal and California tax savings come to roughly $20,700 for the year. Three comparable-rate quotes per type of event live in the documentation file along with minutes, agendas, and the per-event ACH records.

What You Cannot Do

The boundaries of the rule are well-defined, and the failure cases are well-litigated:

• Sham rentals with no business purpose. Inviting your spouse over for "a meeting" and writing yourself a $3,500 check. The Tax Court calls this what it is.
• Day rates above local comparables. The rate must reflect what an arm's-length renter would pay for the property. Inflating the rate to maximize the deduction creates exposure on both audit and economic-substance grounds.
• Renting in excess of 14 days. Crossing the 15-day line voids the entire §280A(g) exclusion for the year. The rental income returns to Schedule E, the deduction on the business side still stands but suddenly looks worse, and §280A's vacation-home rules can limit the offsetting personal-side deductions.
• Renting for personal use disguised as business. Hosting a birthday party for the founder's spouse and calling it a "team appreciation event" does not work. The business purpose must dominate the event.
• Skipping the rental agreement. No written agreement, no per-event documentation, payment by year-end journal entry = audit loss.

What Goes Wrong When Owners DIY It

The most common Augusta Rule mistake we see at intake: a one-line $49,000 December journal entry from the S-corp to the owner with no comparables, no per-event documentation, and no calendar log. On audit, the deduction is disallowed in full, the rent collapses back into the owner's personal income at the marginal rate, and accuracy-related penalties under §6662 stack at 20%. The cost ranges from $25,000 to $40,000 of restored tax and penalties for a single audited year, which usually wipes out three to four years of the prior strategy's savings.

DIY tax software handles the deduction mechanic on the business return, but it does not generate the rental agreement template, build the comparables file, or track per-event documentation. Those are the items that decide whether the deduction survives a Form 4564 information document request, and they are where an engagement pays for itself.

How This Fits with Other Entity Tax Moves

The Augusta Rule is one of several owner-level tax planning moves that benefit closely held businesses. If you operate as an LLC and want to evaluate whether an S-corp election would amplify Augusta Rule savings along with payroll-tax savings on owner compensation, our LLC to S-corp conversion guide walks through the numbers. If you are still picking an entity, the S-corp vs. LLC comparison covers the trade-offs.

Founders who run lean operations from a home office sometimes ask whether the Augusta Rule stacks with the home office deduction. It does, with careful planning: the home office deduction applies to space used regularly and exclusively for business, while the Augusta Rule applies to events on days the rest of the home is rented. They are separate provisions, and a well-built documentation file can support both. Tech operators looking at the full picture often pair this with the moves in our startup founder tax planning hub.

When to Talk to Us

The Augusta Rule is high-payoff and low-effort once the documentation system is in place. For most Bay Area owners running an S-corp or LLC, fourteen well-planned event days produce $15,000 to $30,000 in annual tax savings with one weekend of upfront setup. The cost of getting it wrong is a denied deduction plus interest plus accuracy-related penalties, which can erase several years of savings in a single audit.

At Silicon Valley Tax we help business owners stand up the Augusta Rule the right way: market-rate comparable research for your specific property, the documentation template that lives in your records, the entity tax reporting on both sides, and the calendar discipline to stay inside fourteen days. We do not draft the rental agreement itself (that is attorney work), but we coordinate the tax side end to end.

Book a complimentary consultation and we will run the numbers on your property, your business, and a realistic 14-day plan for the year.
