Cell phones used for business are deductible for the business-use percentage. This includes both the monthly plan and the device purchase. If you use your phone 60% for business, deduct 60% of your monthly plan and 60% of the purchase price.
Getting the deduction right is not just about whether it is allowed — it is about how you set it up.
Estimate the percentage of time you use the phone for business calls, emails, apps, and work-related activities vs. personal use.
Keep monthly phone bills. Note your estimated business-use percentage. For the device, keep the purchase receipt.
Apply the business-use percentage to monthly plan costs. Use Section 179 for the business-use portion of the device. Deduct on Schedule C.
Do not claim 100% if you use the phone personally. A separate business phone allows 100% deduction but is not required.
If your S-Corp provides a company phone as a working condition fringe benefit, the full cost is deductible to the corporation and tax-free to you.
When structured correctly, this deduction can significantly reduce your taxable income.
Here is how this deduction typically works in real situations:
A freelancer uses their iPhone 70% for business. Monthly plan is $100. Phone cost was $1,200.
An S-Corp provides a company iPhone to the owner as a working condition fringe benefit.
A business owner deducts 100% of their personal iPhone used primarily for personal calls and social media.
Key Takeaway: The difference between a valid deduction and a denied one usually comes down to documentation, usage percentage, and proper structuring. The same expense can be fully deductible, partially deductible, or not deductible at all — depending on how it is handled.
The 'Augusta Rule,' codified in IRC §280A(g), allows a homeowner to rent out their primary residence for 14 days or less during a tax year without having to report the rental income on their tax return. This income is completely tax-free, and you do not deduct any associated expenses. It's a specific exemption from the general rules of rental income.
📞 Book a Free Call →To qualify for the Augusta Rule, you must be renting out your 'dwelling unit,' which includes your primary residence. There are no specific ownership duration requirements beyond simply owning and residing in the home. The key is that the rental period for that dwelling unit does not exceed 14 days during the tax year.
📞 Book a Free Call →For the purpose of the 14-day limit under IRC §280A(g), any part of a day that your dwelling unit is rented out counts as a full day. So, even if a tenant occupies your home for only a few hours on a specific day, that day counts towards your 14-day maximum. Careful tracking of rental periods is essential.
📞 Book a Free Call →Determining fair market rent (FMR) is crucial, especially when renting to a related party like your S-Corp. You should obtain comparable rental rates for similar properties in your area for short-term, event-specific rentals. This could involve consulting local real estate agents, looking at Airbnb/VRBO rates for similar homes during peak times, or getting formal appraisals to justify the rental amount.
📞 Book a Free Call →For an Augusta Rule rental, you need to keep robust documentation. This includes a formal lease agreement with your business (or external tenant), proof of payment (e.g., bank statements showing the rental income), evidence of fair market rent (comparable listings, appraisals), and a clear calendar or log showing the exact rental dates. This substantiates the 14-day limit and the rental amount.
📞 Book a Free Call →The Augusta Rule (IRC §280A(g)) applies to the 'dwelling unit' as a whole. While the IRS hasn't explicitly prohibited renting only a portion, the spirit of the rule and common practice usually involves renting out the entire home. If you only rent a room, it might be harder to justify a significant fair market rent to a business, and could raise questions about the primary purpose of the rental.
📞 Book a Free Call →Yes, your S-Corp can pay you, the owner, fair market rent for using your personal home for legitimate business meetings, board meetings, or other corporate events. This is a common strategy to extract tax-free income from your S-Corp under the Augusta Rule. The rental income is tax-free to you personally, and the rent paid is a deductible expense for your S-Corp.
📞 Book a Free Call →When your S-Corp pays you rent under the Augusta Rule, the rental payment itself is a deductible business expense for the S-Corp. This reduces the S-Corp's taxable income, which then reduces the pass-through income allocated to you as a shareholder. The rent you receive personally, however, is tax-free under IRC §280A(g) and is not reported as income on your personal return.
📞 Book a Free Call →No, if you strictly adhere to the 14-day rental limit and do not deduct any expenses related to the rental, you do not need to file any specific IRS forms to claim the Augusta Rule exemption. The rental income is simply excluded from your gross income, meaning it is not reported on your Form 1040 at all.
📞 Book a Free Call →Common mistakes include exceeding the 14-day limit, failing to establish and document fair market rent, especially for related-party rentals, and deducting expenses related to the rental. Another red flag is renting to a related party (like your own business) without a legitimate business purpose for the rental or with disproportionately high rent compared to market rates. Lack of proper documentation is a primary audit trigger.
📞 Book a Free Call →Yes, utilizing the Augusta Rule for a temporary rental period does not preclude you from claiming a home office deduction for other parts of the year, provided you meet the stringent requirements for the home office deduction (IRC §280A(c)). These are separate deductions. The Augusta Rule applies to the full dwelling unit rental, while home office is for a specific, exclusive, and regular use portion.
📞 Book a Free Call →If you rent your home for 15 days or more, the Augusta Rule (IRC §280A(g)) no longer applies to any of the rental income. In this scenario, all rental income received (for all 15+ days) becomes taxable, and you would then be able to deduct ordinary and necessary rental expenses, subject to the passive activity loss rules, on Schedule E (Form 1040).
📞 Book a Free Call →No, there are no specific dollar limits or thresholds for the amount of rent you can receive under the Augusta Rule (IRC §280A(g)). As long as the rental period does not exceed 14 days and the rent reflects fair market value, the entire amount of rental income is tax-free, regardless of how large it is. The key is the duration, not the amount.
📞 Book a Free Call →The Augusta Rule (IRC §280A(g)) applies to a 'dwelling unit' that you use as a residence. While it's most commonly applied to a primary residence, it can potentially apply to a second home or vacation property if you use it for personal purposes for the greater of 14 days or 10% of the total days rented during the year. However, the 14-day rental limit still applies to the dwelling unit itself.
📞 Book a Free Call →Yes, the Augusta Rule (IRC §280A(g)) applies to the total number of days your dwelling unit is rented out during the tax year, regardless of how many different tenants occupy it. As long as the cumulative rental period for the dwelling unit does not exceed 14 days, the income remains tax-free. You must meticulously track each rental period.
📞 Book a Free Call →While the Augusta Rule (IRC §280A(g)) provides a federal income tax exemption, state tax laws can vary significantly. Some states may conform to the federal rule, while others may have different rules or require you to report all rental income. You should consult with a tax professional familiar with your specific state's income tax regulations.
📞 Book a Free Call →If you co-own a home, the 14-day rental limit under IRC §280A(g) applies to the dwelling unit itself, not per owner. So, if the co-owned home is rented for a total of 10 days, both co-owners would individually exclude their share of the rental income. Each co-owner must still ensure they meet personal use requirements for the dwelling unit.
📞 Book a Free Call →As of now, there are no specific proposed law changes for 2025 or 2026 that directly target or alter the Augusta Rule's (IRC §280A(g)) 14-day rental exemption. Tax laws are subject to change, but this particular provision has remained stable for many years. It's always wise to stay updated on legislative developments.
📞 Book a Free Call →No, if you are utilizing the Augusta Rule (IRC §280A(g)) and renting your home for 14 days or less, you cannot deduct any expenses related to that rental activity, including cleaning fees, property management fees, utilities, or depreciation. The trade-off for tax-free income is the inability to deduct associated costs.
📞 Book a Free Call →Yes, you can potentially claim both the Augusta Rule rental (for the entire dwelling unit for up to 14 days) and a home office deduction (for a separate, exclusive, and regular use portion of your home) in the same tax year. These are distinct provisions. The Augusta Rule applies to temporary whole-house rentals, while the home office deduction under IRC §280A(c) is for continuous business use of a specific area.
