Is External Monitor Tax Deductible? 2026 Guide
Yes — Deductible
Yes, an external monitor used for business is tax deductible. Monitors under $2,500 can be expensed immediately under the de minimis safe harbor; more expensive monitors can use Section 179.
IRS Form: Schedule C, Line 18
Conditions & Requirements
- Monitor must be used for business purposes
- If used for both business and personal, only the business-use percentage is deductible
- Under $2,500: expense immediately using de minimis safe harbor
- Over $2,500: use Section 179 or depreciate over 5 years
What the IRS Says
The IRS treats monitors as business equipment. Under the de minimis safe harbor election (Rev. Proc. 2015-20), items costing $2,500 or less can be expensed immediately rather than depreciated. Section 179 allows full expensing of qualifying equipment in the year of purchase with no dollar-per-item limit. Monitors are 5-year MACRS property if depreciated.

Keeping Your External Monitor Receipts Straight
Knowing external monitor qualifies is the easy part. Proving it eleven months later, from a receipt that faded in your glovebox, is where this deduction usually gets lost. Photograph the receipt when you get it and TaxTidy reads the vendor, the amount and the date off it in about three seconds, then files it under Schedule C, Line 18 — the same line you'll claim it on.
The documentation checklist above is the part most people only think about in April. Your Audit Readiness Score keeps it in front of you all year: it counts the expenses with no receipt attached, the ones still sitting uncategorized, and the ones missing a date or a vendor name. You see the gaps while you can still fix them.
If you are unsure whether a particular external monitor charge counts, ask Fin. He answers in plain English, using your actual expenses — not a generic help article.

Frequently Asked Questions
Can I deduct a 4K monitor for my business?
Yes. Any monitor used for business is deductible regardless of resolution or specifications. If under $2,500, expense it immediately. If over $2,500, use Section 179.
Can I deduct multiple monitors?
Yes. Each monitor is treated as a separate item for the de minimis safe harbor. Two $1,500 monitors are two separate $1,500 expenses, both under the $2,500 threshold.
What if I use the monitor for both work and personal use?
Deduct only the business-use percentage. If you use the monitor 80% for work, deduct 80% of the cost.
