The Augusta Rule (§280A) for Founders: Rent Your Home to Your S-Corp — Audit-Safe

By Rafael Negreiros — running an S-corp since 2019. The numbers below come from my own implementation; the methodology is what matters for your situation. → Full author bio

If you run an S-corp or C-corp and work primarily from home, you are sitting on a legal mechanism that most founder tax articles either misexplain or miss entirely. IRC Section 280A(g) — commonly called the Augusta Rule — lets a homeowner rent their personal residence to a separate business entity for up to 14 days per year, collect that rental income completely tax-free at the federal level, and allow the business to deduct the same payment as an ordinary business expense. That is a genuine double-sided tax benefit baked directly into the Internal Revenue Code. The Augusta Rule S-corp founder 2026 opportunity is real — but the execution details are what separate a clean deduction from an audit liability.

I have run my own S-corp since 2019, and when I first mapped this strategy I was struck by how tight the system has to be: the documentation stack, the payment trail, the fair-market-value research. Done right, it is an infrastructure-level optimization — something you set up once, run annually, and maintain as a process. Done carelessly, it hands the IRS a clean disallowance. This article walks through the mechanics, the founder-specific constraints, and the documentation system I use.

What Section 280A(g) Actually Says

The statute is cleaner than most summaries suggest. Under 26 U.S. Code § 280A(g), if a dwelling unit that you use as a residence is rented for fewer than 15 days during the tax year, then: (1) no rental-expense deductions are allowed on the personal side, and (2) the income derived from that rental is not included in gross income under Section 61. That second clause is the mechanism. The rental income simply does not appear on your federal return. The business, meanwhile, deducts the payment as an ordinary and necessary business expense under Section 162 — typically as a meeting or conference facility expense.

The rule predates Augusta National Golf Club’s annual tournament practice of renting local homes; the nickname stuck because Augusta homeowners famously collected tax-free rental income from Masters attendees for decades. The underlying provision has been in the code since 1976 and is structurally unchanged.

The Founder-Specific Constraint Most Articles Skip

Here is the part that separates a useful founder article from a misleading one: the strategy does not work if you are a sole proprietor or a single-member LLC taxed as a disregarded entity.

The entire mechanism depends on a genuine transaction between two separate taxpayers — you as an individual homeowner, and your business as a distinct legal entity. When you are a sole proprietor or a single-member LLC (SMLLC) that has not elected corporate taxation, the IRS treats you and your business as the same taxpayer. You cannot rent your home to yourself and claim a deduction. The payment is circular — it is not a deductible business expense because there is no arm’s-length counterparty. As the CPA guidance from Fraim, Cawley & Company states plainly: “You cannot ‘rent’ your own home to yourself as the same taxpayer and expect a rent deduction to hold up.”

The qualifying entity structures are:

• S-corporation (the most common founder structure where this applies)
• C-corporation
• Multi-member LLC (taxed as a partnership, not a disregarded entity)

If you are currently operating as a sole proprietor or SMLLC and this strategy interests you, the prerequisite is entity restructuring — not a documentation tweak. That is a separate analysis, but it is the reason the Augusta Rule conversation and the S-corp election conversation often happen together. If you are already working through the OBBBA’s mid-year tax implications, the OBBBA mid-year tax audit framework we covered earlier this year is a useful companion piece.

The 14-Day Hard Cap: All-or-Nothing Rule

This is the single most dangerous misunderstanding about the Augusta Rule. Many founders assume the excess days are simply disqualified. They are not — the cap is binary. One extra day over 14 converts all rental income from tax-free to fully taxable, retroactively for the entire year. Maintain a real-time day-count log and never schedule the 15th day.

The Math: A Real Founder Scenario

Let me walk through numbers from a scenario close to my own setup — a solo founder running an S-corp in a mid-size metro market (Denver, CO), working primarily from home, with a dedicated home office and a living/dining area suitable for small board or strategy meetings.

Step 1: Establish Fair Market Value

Rent must reflect what the market would charge for comparable meeting or event space. Here is the methodology that produces a defensible rate — the specific dollar figure matters less than the documentation behind it.

How to pull your own market comps (the step that makes this audit-safe): Search Peerspace for “[your city] + private home + meeting space,” filter for half-day and full-day bookings, and screenshot the top 5 results including the URL and today’s date. Repeat for hotel conference rooms on a major hotel brand site for your city. Those screenshots become your rate-justification file.

For my Denver market in June 2026, I researched three local comparables:

• Peerspace listings for private home meeting spaces in Denver, CO (screenshots dated June 2026): $95–$150/hour, or approximately $760–$1,200/full day
• Marriott/Hilton conference room rentals, Denver (small conference room, full day): $450–$800
• Coworking day passes with private room access (WeWork, Denver): $75–$150/day

Based on the full-day comparable (the most analogous to an all-day board meeting at home), I set the rental rate at $900/day — within the documented hotel conference room range for Denver. Your market will differ: rates in Manhattan or San Francisco typically run $1,200–$2,000/day for comparable space; Boise or Omaha might support $400–$600/day. Pull your own comps and document them. The methodology is the defense, not the number.

Step 2: Calculate the Annual Benefit — Two Scenarios

Scenario A: 12 rental days at $900/day (mid-size market)

At $900/day for 12 days, the S-corp transfers $10,800 tax-free to the founder — money that would otherwise have been subject to income tax as wages or distributions.

Scenario B: 14 rental days at $1,000/day (higher-rate market or maximized cap)

Note: These figures are illustrative estimates. Actual tax savings depend on your effective federal and state rates, entity structure, and deductibility of specific expenses. Your CPA should run the numbers for your situation.

The beauty of this from a systems perspective is that the money moves from the corporation (where it was subject to payroll and income tax as W-2 wages or distributions) to you personally as tax-free rental income. It does not eliminate the corporate deduction — it replaces a taxable transfer with a non-taxable one.

This pairs naturally with the broader income-layering strategies covered in our piece on founder income levers and the ACA subsidy cliff — because Augusta Rule income does not count as earned income, it also does not trigger self-employment tax, and depending on how you structure your W-2 salary, it may not affect your ACA subsidy calculation.

The Audit-Safe Documentation Stack

This is where most founder implementations fail. The IRS does not challenge the strategy itself — it challenges the documentation. A rental arrangement between an S-corp and its sole shareholder is a related-party transaction by definition, and the IRS applies heightened scrutiny to those. Your documentation has to be good enough to convince an agent who is professionally skeptical.

Here is the seven-element system I run:

1. Written Rental Agreement

A formal lease or rental agreement, signed before the first rental day, specifying: the property address, the dates to be rented, the per-day rate, the business purpose, and payment terms. This is your foundation. Without it, you have no documented agreement — just a series of payments that look informal.

2. Meeting Agendas (Prepared in Advance)

Each rental day needs a documented business purpose. Prepare a typed agenda before the meeting day covering specific business topics: revenue review, strategic planning, hiring decisions, product roadmap, financial review. Generic labels like “business meeting” are weak. Specific agenda items — “Q3 cash flow projections,” “assessment of contractor vs. employee for role X,” “2027 pricing strategy” — hold up under scrutiny.

3. Board Minutes or Meeting Notes

Document what was discussed and decided. For an S-corp with a single shareholder, these are sometimes called “written consents” rather than minutes — the format is less important than the substance. Note who was present, what was discussed, what decisions were made, and any action items. These are created during or immediately after the meeting, not reconstructed months later.

4. Attendee Records — and the Solo-Meeting Rule of Thumb

List everyone present by name and role. Solo founder meetings are the weakest version of this — if you are meeting with yourself alone, it is harder to substantiate a board meeting. Tax practitioners commonly recommend that at least half of your rental days include a third-party participant — advisor, attorney, accountant, or contractor — to substantiate board-meeting substance. A single solo meeting among 12 or 14 total days is generally less risky than a full calendar of solo days, but confirm the acceptable ratio with your CPA. For IRS guidance on meeting substantiation, the underlying standard is the ordinary and necessary business expense test under § 162; your documentation should demonstrate that the meeting had economic substance beyond just generating a deductible payment.

5. Fair Market Value Comparables File

Save screenshots of at least three comparable venues (Peerspace, hotel meeting rooms, coworking spaces) with their rates, the URL of each listing, the date you pulled the data, and the specific city. This is your rate justification. If your rate is significantly above what comparable venues charge in your market, the IRS can disallow the excess — so stay within the documented range and name the market. An undated screenshot from an unnamed zip code is not audit-safe documentation. A dated screenshot from “Peerspace, Denver CO, June 8, 2026” with the URL is.

6. Clean Payment Trail

The S-corp must actually pay you. An ACH transfer or business check from the corporate account to your personal account, on or around each rental date, with the memo noting “Facility rental — [date].” Cash payments are not acceptable for audit purposes. Do not let this sit as an accounting entry — the money has to move.

7. Day-Count Tracker

Maintain a real-time log tracking each rental day as it is used. The 14-day cap is absolute — exceeding it by even one day eliminates the § 280A(g) exclusion for all rental income that year, not just the overage. I use a simple running document updated after each rental day.

What to Audit Before You Implement

Before writing the first rental agreement, run through this pre-flight checklist:

1. Confirm your entity qualifies. S-corp, C-corp, or multi-member LLC only. If you are a sole prop or SMLLC, fix the entity structure first.
2. Verify your S-corp has a genuine business need for meeting space — board strategy sessions, financial reviews, planning offsites. The business purpose must be real.
3. Research local comparable rates before setting your rental price. Pull three comparables, document them with URLs and the current date, name the metro market, and price within range.
4. Check your state’s treatment. Most states conform to § 280A(g), but several high-concentration founder states create complications. California conforms to the federal income exclusion, but California S-corps pay a 1.5% franchise tax on net income that affects the overall calculus. New York generally conforms but has its own S-corp treatment that may affect pass-through income. New Jersey does not recognize S-corp elections the same way federally — the rental income exclusion may still apply at the individual level, but NJ corporate treatment adds complexity. If you are in CA, NY, NJ, or Massachusetts, confirm your specific state treatment with a CPA before executing — do not assume full conformity.
5. Separate Augusta Rule space from home office space. The space rented under § 280A(g) cannot be the same square footage claimed as a dedicated home office under § 280A(c). See the FAQ below for details.
6. Coordinate with your bookkeeper. The S-corp needs to categorize the payments correctly — typically as “facility rental” or “conference expenses” — and the personal side needs to be flagged as non-reportable rental income.

The operational overhead here is modest once the system is in place. Think of it as a quarterly process: plan three to four meeting days per quarter, prepare agendas in advance, document the sessions, process the transfers, and file the comparables. That is roughly two to three hours of administrative work per year for a $5,800–$10,500 benefit depending on your market and day count. On a per-hour basis, it is one of the highest-leverage cost-system optimizations available to a home-based founder — similar in spirit to the regular SaaS audit that we use to claw back unnecessary software spend, except this one does not require cutting anything.

FAQ: Augusta Rule for S-Corp Founders

Can a single-member LLC use the Augusta Rule?

No. A single-member LLC taxed as a disregarded entity is treated as the same taxpayer as its owner under the IRS default rules. Renting your home to your own SMLLC is not an arm’s-length transaction — there is no separate taxpayer on the other side of the lease — and the deduction will be disallowed. To qualify for the § 280A(g) income exclusion and the corresponding business deduction, you must operate through an S-corp, C-corp, or multi-member LLC taxed as a partnership. This is the most commonly missed disqualification in Augusta Rule coverage, and it is a hard rule with no workaround short of entity restructuring.

Can I use the Augusta Rule if I have a home office deduction?

Yes, but the spaces must be distinct. The home office deduction (Section 280A(c)) covers the square footage you use regularly and exclusively for business — your dedicated office room. The Augusta Rule (Section 280A(g)) covers different space within your home that you rent to your S-corp for meeting purposes — the living room, dining room, outdoor area, or other common-area space used for board meetings. The dedicated home office space cannot be the same square footage rented to the S-corp under § 280A(g). The Augusta Rule rental should cover non-office common areas. Keep the two provisions separated in your documentation, your rental agreement, and your bookkeeper’s records. Confirm the separation is clean with your CPA.

What if my S-corp’s only shareholder is me — does the arm’s-length requirement still hold?

Yes. A 100%-owned S-corp is still a legally separate entity from its shareholder. You and your S-corp are distinct taxpayers in the eyes of the IRS, which is why the Augusta Rule can work — you are renting from yourself-as-individual to your-business-as-separate-entity. The heightened documentation requirement for related-party transactions means your paperwork has to be cleaner, not that the strategy is disqualified. The IRS expects the arrangement to look exactly as it would if the business were renting a space from an unrelated third party.

Does the rental income affect my S-corp’s reasonable compensation requirement?

No. Rental income received by you as an individual is separate from the W-2 wages your S-corp pays you as an employee-shareholder. The reasonable compensation analysis (how much the S-corp must pay you in salary before taking distributions) is not affected by Augusta Rule rental payments. The rental payment is a business expense to the S-corp, not a substitute for wages — and it does not count as earned income for Social Security or Medicare purposes on your personal return, which is part of what makes it tax-efficient.

The Bottom Line: Augusta Rule S-Corp Founder 2026

The Section 280A home rental business deduction is a stable, IRS-code-backed mechanism that lets an S-corp founder move $10,800–$14,000 per year from the corporate account to their personal account with no federal income tax on the receiving end — with the combined corporate deduction and personal exclusion producing a real after-tax benefit of $5,800–$10,500+ depending on your market rate and effective tax rates. That range is anchored to the two worked scenarios above, not to uncited estimates.

The Augusta Rule S-corp founder 2026 window is open and the rules are stable — OBBBA made no changes. The implementation system is not complex, but it requires discipline: a written agreement before the first rental day, advance agendas, contemporaneous meeting notes, a clean payment trail, and a day-count log that never lets you cross 14. Build it as a process — quarterly calendar blocks, a documentation folder, a recurring bookkeeping entry — and it becomes invisible overhead for a meaningful annual benefit.

Your next step: pull up your S-corp operating calendar and identify legitimate board or strategy meeting days for the remainder of 2026. If you are reading this in June 2026, you have roughly 26 weeks left in the tax year — enough time to schedule 8–10 qualifying days before year-end. Then get three comparable venue quotes from your local market with URLs and today’s date, set a defensible daily rate, and draft the rental agreement before the first scheduled day. Bring your CPA into the conversation before you execute — they can confirm your rate, review the documentation format, and ensure your state does not create additional filing requirements.
