Freelance Designer Saves $18K with Home Office + Vehicle Depreciation + SEP-IRA

The Problem

This client was a freelance UX/graphic designer earning $185,000 in net Schedule C income. The client worked exclusively from a dedicated 280 sq ft home studio and had recently purchased a $62,000 SUV (over 6,000 lbs GVWR) used 85% for business. The prior CPA had been using the standard mileage rate for the vehicle ($0.70/mile) and had not claimed a home office deduction, advising the client that "the home office deduction triggers audits."

The CPA's advice was outdated and cost the client significant deductions. The IRS has publicly stated that properly documented home office deductions do not increase audit risk. The standard mileage rate on the SUV produced a deduction of approximately $10,500/year, whereas the actual expense method with Section 179 depreciation on the $62,000 vehicle would produce a first-year deduction of $52,700 (85% business use x $62,000) plus ongoing fuel, insurance, and maintenance deductions. The client also had no retirement plan despite earning well into the six-figure range.

AE Tax Strategy

1. Home Office Deduction Under IRC §280A(c)(1)

We implemented the home office deduction using the actual expense method (not the simplified method, which caps at $1,500). The 280 sq ft dedicated studio represented 14% of the home's total square footage. Allocable expenses included mortgage interest, property taxes, insurance, utilities, maintenance, and depreciation on the home. Total home office deduction: $8,400/year. At the client's combined 24% federal plus 7.65% Wisconsin marginal rate, this produced $2,660 in annual tax savings.

2. Section 179 Vehicle Depreciation Under IRC §179(b)(6)(B)

The client's SUV exceeded 6,000 lbs GVWR, qualifying it for full Section 179 expensing under IRC §179(b)(6)(B) (which exempts vehicles over 6,000 lbs from the luxury auto depreciation caps of IRC §280F). The first-year deduction was $52,700 (85% business use x $62,000 cost). At the 31.65% combined rate, this produced $16,680 in first-year tax savings. In subsequent years, the ongoing actual expense deductions (fuel, insurance, maintenance, tolls) at 85% business use produced approximately $5,400/year in deductions, or $1,710 in annual tax savings.

3. SEP-IRA Under IRC §408(k)

We established a SEP-IRA (Simplified Employee Pension) allowing a contribution of up to 25% of net self-employment income (after the SE tax deduction). The maximum contribution was $38,600 based on the client's adjusted net earnings. At the 31.65% combined rate, this produced $7,900 in annual tax savings in ongoing years. While we recommended transitioning to a Solo 401(k) in the following year (for the additional employee deferral), the SEP-IRA was appropriate for the current year because it could be established and funded up to the tax return filing deadline.

Before & After Comparison

Tax Category	Before	After	Savings
Home Office Deduction	$0	$8,400	$8,400
Vehicle Section 179 (Year 1)	$10,500	$52,700	$42,200
SEP-IRA Contribution	$0	$38,600	$38,600
Annual Ongoing Savings	$0	$18,000	$18,000
Total	$10,500	$18,000	$18,000

Key Takeaways

• The actual expense method for home office deductions typically produces 3-5x larger deductions than the simplified method ($5/sq ft, max $1,500) for dedicated home offices of 200+ sq ft.
• Vehicles over 6,000 lbs GVWR are exempt from the luxury auto depreciation caps under IRC §280F, allowing full Section 179 expensing in Year 1 — a benefit worth tens of thousands for qualifying SUVs and trucks.
• SEP-IRAs can be established and funded up to the tax filing deadline (including extensions), making them ideal for last-minute retirement planning — but Solo 401(k) plans must be established by December 31.
• The home office deduction does not increase audit risk when properly documented — the IRS has confirmed this publicly, and the deduction is a legitimate business expense for qualifying taxpayers.
