Accountable Plan for S-Corps: The IRS-Approved Way to Reimburse Yourself Tax-Free

S-corp owners can legally reimburse themselves for home office, mileage, cell phone, and internet with zero payroll tax, if the plan is documented right. Board resolution template, receipt rules, 60-day submission window, and the mistakes that turn valid reimbursement into extra W-2 wages.

Why Accountable Plans Matter

Without an accountable plan, every dollar your S-corp 'reimburses' you is taxable wages. With one, those reimbursements are tax-free to you and deductible to the corp.
Most common reimbursements: home office, business cell phone, internet (business portion), business mileage, business travel.
Required for S-corp owners since the Tax Cuts and Jobs Act (2017) eliminated employee business expense deductions for W-2 employees on Schedule A.
Without one, you're paying tax on money you used to run the business and getting nothing back.

The Three IRS Requirements

1. Business connection: expenses must be ordinary and necessary for the corporation's business.
2. Substantiation: actual receipts, documentation, business purpose, submitted to the corp within a reasonable time (typically 60 days).
3. No excess payments retained: any reimbursement above documented expenses must be returned to the corp.
Miss any of the three and the IRS reclassifies reimbursements as taxable wages with payroll tax owed.

Setting It Up

Written accountable plan resolution: adopted by the board and kept with corporate records.
Defined reimbursement categories: home office (square footage method), mileage (IRS standard rate × business miles), cell phone (business percentage of bill), internet (business percentage), and travel.
Monthly or quarterly expense reports: employee submits, corp reviews, corp reimburses.
Separate the bookkeeping: 'Accountable Plan Reimbursements' as its own expense category in QuickBooks/Xero.
Don't run reimbursements through payroll; they're not wages.

Home Office Reimbursement (Highest Value)

Method 1 (square footage): home office sq ft / total home sq ft × (utilities + insurance + repairs + depreciation + property tax). Most accurate.
Method 2 (simplified): $5/sq ft up to 300 sq ft = $1,500 max. Easier but lower value.
Most owners can reimburse $2,000–$5,000/year for a real home office. At 32% marginal rate, that's $640–$1,600 in federal tax savings annually.
Documentation: home office photo, measurements, utility bills, and mortgage interest / rent receipts.

Other High-Value Reimbursements

Cell phone: 80% business use is common for owner-operators. Bill is $100/mo → $80/mo reimbursement → $960/year tax-free.
Internet: 50–80% business use common when working from home. Bill is $80/mo → $40–$64/mo reimbursement.
Mileage: IRS standard rate (set annually). Document odometer reads and business purpose for each trip.
Business travel: hotels, flights, meals (50% deductible), tips, and parking, all reimbursable with receipts.
