Why This Tool Exists
A home office reimbursement done the right way is not about squeezing every dollar. It is about building a repeatable process your CPA can defend.
This calculator estimates a conservative reimbursement amount using a square-foot allocation, then gives you a documentation checklist so the math actually survives real-world execution.
Execution note: Run the tool, then write down your assumptions and keep the receipts and logs as you go. The strategy that wins on paper only matters if your process holds up in the real world.

What This Calculator Is Actually Doing
You enter your home's total square footage and your dedicated office square footage to compute a business-use percentage.
Then you add the home expenses you want to reimburse (utilities, internet, rent, insurance, repairs, HOA, and similar).
The calculator allocates each expense by the business-use percentage, then suggests a monthly reimbursement cadence so you can stop doing year-end reconstructions.
Execution Notes (Where People Get Burned)
If the space is not exclusive and regular, the math does not matter. The qualification gate matters first.
If you cannot show a simple policy, a reimbursement request, and contemporaneous receipts, your accountant ends up cleaning up a mess at tax time.
Keep it boring: monthly reimbursement, one folder per year, and the same worksheet every month.
What To Hand Your CPA
A one-page accountable plan policy (effective date, what is reimbursable, and how reimbursements are requested).
Your square-foot calculation (floor plan or measurement notes, plus photos).
Expense proof (bills, receipts, statements) and a monthly reimbursement log.
Documentation Checklist (Keep It Defensible)
- Create a one-page objective memo before you execute (what outcome you are trying to buy).
- Store your assumptions and calculations in a dated PDF (no year-end reconstructions).
- Keep evidence in the same folder structure every month (receipts, logs, approvals).
- Ask your CPA what would make this easy to sign off on, then build that packet.
Primary Sources To Verify Before You Act
Use primary guidance and your own records before you treat any page like a final answer. These are the source layers that should drive the decision.
- IRS business-use-of-home and reimbursement guidance
- IRS S corporation election resources
- Current IRS forms, instructions, and publications for the relevant tax year
- Your actual account statements, payroll reports, entity records, and advisor memos
Frequently Asked Questions
No. This is a reimbursement workflow under an accountable plan. The point is a clean, repeatable process and documentation, not a one-off deduction.
It often shows up in S corp conversations because reimbursements and documentation matter a lot there. The process quality is the real win.
Monthly is usually cleaner because it avoids reconstructing a story after the year ends. This tool shows both so you can pick a cadence you will actually follow.
