Is Electricity Tax Deductible?

Quick Answer: ✅ Yes — electricity is deductible if it's for a business location. For a home office, you deduct the business-use percentage of your electric bill.

The Short Answer

If you run your business from a dedicated office, storefront, or warehouse, your electricity bill is 100% deductible as a business expense. If you work from home, you can deduct the portion of your electric bill that corresponds to your home office space. Either way, the lights you keep on to run your business are a legitimate write-off.

IRS Rules for Deducting Electricity

Electricity is a utility expense, deductible under IRC Section 162 as an ordinary and necessary business expense:

Dedicated Business Location (Office, Store, Warehouse)

• 100% deductible — the entire electric bill for a space used solely for business
• No special forms or calculations needed
• Just categorize it as a utility expense

Home Office

• Deductible as part of your home office deduction using one of two methods:
• Actual expense method: Calculate business-use percentage (office sq ft ÷ total home sq ft), then apply that percentage to your electric bill
• Simplified method: $5 per sq ft (max 300 sq ft = $1,500 max). Electricity is baked into this amount — you can't deduct it separately
• File Form 8829 if using the actual expense method

Mixed-Use Space

• If you rent a space that's partly business, partly personal, only the business percentage of utilities is deductible

How Much Can You Deduct?

Example — Dedicated office:

Your office electric bill is $200/month.

• Annual cost: $2,400
• Deductible: $2,400 (100%)
• Tax savings (est. 25% bracket): ~$600/year

Example — Home office (actual method):

Your home is 2,000 sq ft. Your office is 200 sq ft (10%). Monthly electric bill averages $250.

• Annual electric cost: $3,000
• Business portion: $3,000 × 10% = $300
• Tax savings (est. 25% bracket): ~$75/year

It's not a huge deduction for home offices, but it adds up when combined with rent, internet, insurance, and other home office expenses.

How to Categorize in QuickBooks

• QBO Category: "Utilities" (under Expenses) for a dedicated business location; "Home Office Expenses" for home-based businesses
• Schedule C Line: Line 25 — Utilities (for business locations); Line 30 — Business Use of Home (for home offices)
• Tip: Create sub-accounts under Utilities:

- "Utilities — Electric"

- "Utilities — Gas"

- "Utilities — Water"

- "Utilities — Trash"

- This makes it easy for your CPA to verify and keeps your books clean.

Common Mistakes to Avoid

1. Deducting your entire home electric bill — If you work from home, only the business-use percentage is deductible. Deducting 100% of a residential electric bill is a red flag.
2. Double-dipping with simplified method — If you use the simplified home office method ($5/sq ft), electricity is already included. You cannot also deduct a portion of your electric bill separately.
3. Forgetting electricity at a second location — If you rent a storage unit, workshop, or studio in addition to your main office, that location's electricity is also deductible.
4. Not tracking seasonal variation — Electric bills fluctuate. Use the actual annual total, not an estimate based on one month. Download your utility's annual summary if available.

Record-Keeping Requirements

• Monthly utility bills or statements
• Annual summary from your utility provider (most offer this online)
• For home office: documentation of office square footage and total home square footage
• Payment records (bank statements or auto-pay confirmations)
