Can I Write This Off?

Can I write off a PO box for business?

TL;DR

Yes, you can write off a PO box for business if it is used exclusively for business purposes.

Detailed Answer

A PO box can be deducted as a business expense if it is used solely for business-related correspondence and activities. This expense is considered part of your office expenses. However, if the PO box is used for both personal and business purposes, only the portion attributable to business use can be deducted. For example, if you use the PO box 70% for business and 30% for personal use, you can only deduct 70% of the cost.

Where to Put It on the Tax Form

Schedule C (Form 1040), Part II, Line 18 (Office Expenses)

Real World Example

A freelance graphic designer rents a PO box to receive client checks and business correspondence. The designer uses this PO box exclusively for business, making the entire rental fee deductible.

Calculation Required

A calculation is required for this deduction.

If the PO box is used for both personal and business purposes, calculate the deductible portion by determining the percentage of business use and applying it to the total cost.

Audit Risk & Documentation Tips

Keep receipts or invoices for the PO box rental and document the business purpose. If audited, be prepared to demonstrate the business use of the PO box, such as by showing examples of business correspondence received.
