Recognizing the Business Portion of Purchases That Also Benefit Your Personal Life

Updated over a week ago



Mixed purchases benefit both your business and personal life. Rent for your home and and mileage you put on your car are common examples. An Accountable Plan allows S Corp owners to pay for mixed purchases with personal funds and reimburse themselves for the business portion. This makes it appear as an expense on your Profit & Loss report. The general steps are:

  1. Pay for mixed purchases with personal money

  2. Calculate the business portion using the accountable plan found on the reimbursement tab on your Member Dashboard

  3. Transfer money from your business checking to your personal checking.

  4. Upload your previous month's bank statement through the document section in your Member Dashboard

  5. Your transactions will be categorized as “Employee Reimbursement” by your Collective Accounting Advisor

Common Examples

For Renters

Divide the square footage of your home office by the total square footage of your home (ex. 150 sq ft/2,000 sq ft). Multiply that percentage by home renting expenses: rent, utilities, renter's insurance, etc.

For Homeowners

Divide the square footage of your home office by the total square footage of your home (ex. 150 sq ft/2,000 sq ft). Multiply that percentage by home owner expenses: mortgage interest only, property tax, HOA dues, utilities, homeowner's insurance, etc. Any principal paid on your mortgage is not an expense, it's paying off a loan, so it can't be included in this process.

Note: For both renters and homeowners, to be eligible for the home office reimbursement, your office space generally must be exclusively used for business on a regular basis and it also must be your principal place of business.

Auto Expenses

Don't track gas, maintenance, repair, lease, and loan expenses for your car. Instead, track your business miles driven and multiply by the annual IRS mileage reimbursement rate. Options to track miles are:

  1. Odometer readings on a paper/digital log

  2. Third-party software: Mile IQ, Timeero, TripLog Beacon, Everlance, etc.


These detailed steps and the spreadsheet will walk you through the entire process.

  1. Complete the reimbursement every month.

  2. Transfer funds from your business checking account to your personal checking account with a check or an online transfer. Make a note in the memo of the check or bank transfer (if bank allows) for the month the transfer is for.

  3. Save all documentation for 3 years.

  4. The IRS wants this process repeated consistently once a month.

  5. Please note: Reimbursements should not be ran in Gusto


The accountable plan is a great tool to implement and we want to ensure that you are taking all the optimal deduction while staying in compliance with the IRS. We have established some safe guards to ensure that your accountable plan is being used properly:

  1. Home office percentage: It can be tempting to state that your home office utilizes a large portion of your home to increase your deduction. We want to remind you that the square footage of your home office must be EXCLUSIVELY for business use only. In most cases, we do not recommend that the square footage of your home office exceeds 25% of your entire home. If you have a unique case and in fact have a home office that is in excess of 25% of your entire home then we will require some additional documentation before we can allow you to claim the deduction.

  2. Phone and Internet: It may feel like all you do is work, work, work and you need your phone and internet to do just that. The rules on documenting phone and internet usage for an accountable plan are, like most things with the IRS, fuzzy, and heavy-handed. It would also be highly difficult to justify a mixed use expense where you’re using more than 70% of your phone and internet for business to the IRS. If you were awake from 7am to 10pm every day, you would need to work 11 hours a day solely on business things using your internet and phone in order to exceed 70% usage. (Quick GSheets for playing around fun). So our worksheet does not allow you to exceed, that's right you guessed it, 70%.
