An accountable plan is one of the most underutilized tax planning tools for S-Corp owners. It allows the S-Corp to reimburse the owner-employee for business expenses paid personally (mileage, home office, cell phone, internet, travel, supplies) without the reimbursement being included in the owner’s W-2 income. The reimbursement is deductible by the S-Corp as a business expense. The owner receives the money tax-free. Both sides benefit, and the IRS explicitly allows it under IRC 62(c) and Treas. Reg. 1.62-2.

✓Key takeaway

Accountable plan requirements (Treas. Reg. 1.62-2(c)):

Business connection. The expense must have a business connection (it must be deductible if paid directly by the employer).
Adequate accounting. The employee must substantiate the expense to the employer within a reasonable time (typically within 60 days of incurring the expense). Substantiation means: receipts, mileage logs, or other documentation showing the amount, date, place, and business purpose.
Return of excess. Any reimbursement that exceeds the substantiated expenses must be returned to the employer within a reasonable time (typically within 120 days of receiving the reimbursement).

What an S-Corp owner can reimburse through an accountable plan:

Vehicle mileage. The S-Corp reimburses the owner at the IRS standard mileage rate (70 cents/mile in 2025) for business miles driven in the owner’s personal vehicle. Tax-free to the owner, deductible by the S-Corp.
Home office. The S-Corp reimburses the owner for the business use percentage of home expenses. Two methods: the simplified method ($5/sq ft, up to 300 sq ft, capped at $1,500/year) or the actual method (pro-rata share of rent/mortgage interest, utilities, insurance, repairs, and depreciation).
Cell phone. The S-Corp reimburses the business percentage of the owner’s cell phone bill.
Internet. Same as cell phone: reimburse the business percentage.
Travel and meals. The S-Corp reimburses for business travel (airfare, hotel, meals at 50%) with receipts.
Professional development. Books, courses, subscriptions, conference fees.
Supplies and equipment. Office supplies, tools, software purchased personally for business use.

What is NOT an accountable plan (nonaccountable plan):

Fixed monthly payments without substantiation (“we’ll pay you $500/month for vehicle expenses” with no mileage log)
Reimbursements without receipts or documentation
Excess reimbursements not returned

A nonaccountable plan payment is included in the employee’s W-2 as wages, subject to income tax and FICA.

How much can an S-Corp owner save with an accountable plan?

Hypothetical example

Round numbers. For current guidance, see IRS S corporation guidance. An S-Corp owner drives 12,000 business miles per year, uses 20% of their home for business, and uses their personal cell phone 75% for business.

Without accountable plan: The owner cannot deduct unreimbursed employee expenses on their personal return (the TCJA eliminated the miscellaneous itemized deduction for W-2 employees, and the OBBBA made that elimination permanent). The deductions are simply lost.

Business miles: 12,000 x $0.70 = $8,400 in deductible expenses LOST
Home office (20% of $24,000 annual home costs): $4,800 LOST
Cell phone (75% of $1,200/year): $900 LOST
Total lost deductions: $14,100

With accountable plan: The S-Corp reimburses the owner:

Mileage: 12,000 x $0.70 = $8,400 (tax-free to owner, deductible by S-Corp)
Home office: $4,800 (tax-free, deductible)
Cell phone: $900 (tax-free, deductible)
Total reimbursement: $14,100

Tax impact: The $14,100 reimbursement reduces the S-Corp’s taxable income (K-1 decreases by $14,100). The owner receives $14,100 tax-free (not included in W-2 income). The reimbursement is NOT subject to FICA.

Compared to paying as additional salary: If the S-Corp paid an extra $14,100 in salary instead:

Income tax: $14,100 x 24% = $3,384
Employee FICA: $14,100 x 7.65% = $1,079
Employer FICA: $14,100 x 7.65% = $1,079
Total tax on additional salary: $5,542

With accountable plan:

Tax on the reimbursement: $0
S-Corp deduction: $14,100 (reduces K-1)
QBI impact: K-1 reduced by $14,100, QBI deduction reduced by $2,820 (20% x $14,100)
Net savings vs. salary: approximately $2,722/year ($5,542 in avoided salary taxes, minus $2,820 in lost QBI benefit)

Setup requirements:

The S-Corp adopts a written accountable plan (a board resolution or corporate minutes documenting the policy)
The owner submits expense reports with documentation (mileage log, home office calculation, cell phone bills) within 60 days
The S-Corp reimburses the documented expenses
Any excess is returned within 120 days
The reimbursement is NOT reported on the W-2
The bookkeeper records the reimbursement as a business expense, not wages

Cost to set up: $0-$500. Annual maintenance runs about 15 minutes a month of expense reporting. The plan pays for itself in tax savings within the first year.

The plan has to be real, not a paper exercise. The IRS looks for a written plan document on file, actual expense reports submitted by the owner, receipts or documentation for each expense, reimbursement payments traceable in the S-Corp’s bank records, and any excess returned within the required timeframe. An owner who writes themselves a check labeled “expense reimbursement” with no documentation behind it has a nonaccountable plan, taxable as wages, even if they call it something else.

Which fringe benefits are tax-free to employees and deductible by the employer?

Several fringe benefits qualify for tax-free treatment to the employee while remaining fully deductible by the employer. Health insurance premiums paid by the employer are excluded from the employee’s income and not subject to payroll taxes. Employer contributions to health savings accounts (HSAs), dependent care assistance programs (up to $5,000), educational assistance programs (up to $5,250 under IRC 127), and group-term life insurance (up to $50,000 of coverage) are all tax-free to employees. De minimis fringe benefits (occasional snacks, holiday gifts of nominal value, personal use of a copier) are excluded from income under IRC 132. For S-Corp owners who hold more than 2% of the stock, health insurance premiums must be reported as W-2 income (though the owner can deduct them on Form 1040, line 17), and other fringe benefit exclusions are generally unavailable.

What entity structure works best for a business with multiple owners?

A multi-member LLC taxed as a partnership is the most flexible default. It files Form 1065 and issues K-1s to each member, with the operating agreement controlling profit allocation, voting rights, and buyout terms. An S-Corp works if all owners are US individuals (no entity or foreign owners), the business has no more than 100 shareholders, and everyone agrees on equal-class stock. A C-Corp is necessary if you want venture capital (preferred stock classes), have foreign owners, or plan to retain significant earnings at the 21% corporate rate. LLCs offer the most flexibility for unequal profit splits, special allocations, and varying capital contributions.
