Quick Answer: ✅ Yes — Monitors used for business are fully deductible as business equipment, typically expensed in the year of purchase.
The Short Answer
A computer monitor purchased for business use is a deductible expense. Whether it's a basic display or an ultrawide for design work, the IRS treats it as business equipment. Most monitors cost under $2,500 and can be expensed immediately without depreciation.
IRS Rules for Deducting a Monitor
Computer monitors are considered listed property or general business equipment under IRS Publication 946. They're classified as 5-year MACRS property (computer peripherals). However, the practical deduction methods are:
- De minimis safe harbor: Monitors costing $2,500 or less are expensed immediately in the purchase year.
- Section 179: For high-end monitors or multi-monitor setups exceeding $2,500 total, you can elect to expense the full amount.
- Bonus depreciation: 60% first-year bonus for 2024 if you choose not to use Section 179.
The monitor must be used more than 50% for business to qualify for Section 179. For home office use, standard home office qualification rules apply (Publication 587).
How Much Can You Deduct?
| Monitor Cost | Best Method | Year 1 Deduction |
| ------------- | ------------- | ----------------- |
| Under $2,500 | De minimis safe harbor | 100% |
| $2,500+ | Section 179 | 100% |
| Multiple monitors (combined) | Section 179 | 100% combined |
| Mixed use (e.g., 60% business) | Any method | 60% of cost |
If you use the monitor for both work and personal activities (Netflix, gaming), only the business-use percentage is deductible.
How to Categorize in QuickBooks
- QBO Category: Computer & Internet Expenses (if expensing) or Computer Equipment (if capitalizing)
- Schedule C Line: Line 22 (Supplies) if under $2,500 and expensed; Line 13 (Depreciation) if capitalized
- Tip: Keep monitors categorized separately from your computer — it makes replacement tracking easier and keeps your fixed asset list clean.
Common Mistakes to Avoid
- Not tracking business-use percentage. If the monitor sits in your living room and the whole family uses it, you need a reasonable business-use allocation.
- Forgetting mounting hardware and cables. The monitor arm, HDMI cables, and display adapters are all deductible too. Track them as separate line items or bundle with the monitor purchase.
- Depreciating a $300 monitor. Use the de minimis safe harbor. Creating a 5-year depreciation schedule for an inexpensive monitor wastes your time and your accountant's.
Record-Keeping Requirements
Keep the purchase receipt with date, vendor, model number, and cost. Document your business-use percentage if the monitor isn't 100% for work. If you're depreciating (rare for monitors), maintain a fixed asset log with the in-service date and depreciation method. Retain all records for at least 3 years from filing.
