Quick Answer
The regular method lets you deduct actual home expenses based on the percentage of your home used for business. If your office is 200 sq ft of a 2,000 sq ft home (10%), you can deduct 10% of mortgage interest, utilities, repairs, and depreciation - often worth $3,000-8,000 annually versus the $1,500 simplified method maximum.

How the regular method calculates your deduction
The regular method for home office deduction works by taking your actual home expenses and multiplying them by the business-use percentage of your home. This typically results in much larger deductions than the simplified method's flat $5 per square foot (capped at $1,500).
Here's the step-by-step process:
1. Calculate your business-use percentage (office square footage ÷ total home square footage)
2. Track all qualifying home expenses throughout the year
3. Apply the business percentage to deductible expenses
4. Claim depreciation on the business portion of your home's basis
Example: $75,000 freelancer with 300 sq ft office
Let's say you're a freelance consultant earning $75,000 annually. Your home is 2,500 sq ft, and your dedicated office is 300 sq ft. Your business-use percentage is 12% (300 ÷ 2,500).
Here are your actual 2026 home expenses:
Simplified method comparison: 300 sq ft × $5 = $1,500 maximum
Your savings:** $5,844 vs $1,500 = **$4,344 additional deduction
At a 24% marginal tax rate, this saves you an extra $1,043 in federal taxes alone.
What expenses qualify for the regular method
Direct expenses (100% deductible):
Indirect expenses (business percentage deductible):
Non-deductible expenses:
Key factors that maximize your deduction
What you should do
1. Measure your office space accurately and calculate your business-use percentage
2. Track all home expenses throughout the year - utilities, repairs, insurance, mortgage interest
3. Keep detailed records of business use and maintain receipts for all expenses
4. Consider depreciation carefully - it must be "recaptured" when you sell your home
5. Compare both methods annually to see which gives you a larger deduction

Key takeaway: The regular method typically saves full-time freelancers $2,000-6,000 more than the simplified method, but requires meticulous record-keeping of all home expenses and business use.

Why consultants often benefit most from the regular method
As a consultant who meets clients in your home office, you're in an ideal position to maximize the regular method deduction. The IRS allows the home office deduction when your space is used regularly for meeting clients, even if it's not your primary business location.
Strategic considerations for consultants
Meeting documentation matters: Keep a log of client meetings in your home office. This strengthens your "regular business use" claim and supports the deduction if questioned.
Dual-use spaces: If you have a formal dining room that doubles as your meeting space, ensure you can demonstrate exclusive business use during business hours. The space doesn't need to be exclusively business 24/7, but it must be exclusively business when you're conducting business.
Higher-value homes = bigger deductions: Consultants often live in higher-value homes with larger mortgage interest, property taxes, and maintenance costs. This makes the regular method significantly more valuable.
Example calculation for consultant
Let's say you're a management consultant with a 400 sq ft home office in a 3,000 sq ft home (13.3% business use). Your home expenses include:
Regular method deduction:** $64,800 × 13.3% = **$8,618
Simplified method:** 400 sq ft × $5 = **$2,000
Additional tax savings:** $6,618 × 24% tax rate = **$1,588
What you should track
Key takeaway: Consultants with client meetings at home and substantial home expenses can often deduct $6,000-12,000 annually using the regular method versus $1,500-2,000 with simplified method.

Best for part-time freelancers evaluating whether the regular method's complexity is worth the additional deduction
When part-time freelancers should consider the regular method
If you're freelancing part-time, the regular method might still be worth it, but you need to run the numbers carefully. The break-even point typically occurs when your home office is larger than 300 square feet OR when you have high home expenses.
Quick decision framework
Definitely use regular method if:
Probably stick with simplified method if:
Example: Part-time freelancer analysis
You freelance 20 hours/week earning $25,000 annually. Your home office is 250 sq ft of a 2,000 sq ft home (12.5% business use).
Your home expenses:
Regular method: $21,000 × 12.5% = $2,625
Simplified method: 250 sq ft × $5 = $1,250
Difference: $1,375 additional deduction = ~$330 tax savings
The trade-off: Is tracking receipts and calculating percentages worth $330? For some, yes. For others, the simplified method's ease wins.
Key takeaway: Part-time freelancers benefit from the regular method when their office exceeds 300 sq ft or when home expenses are substantial, but should weigh the extra $300-800 tax savings against increased complexity.
