A 53-Year-Old Mechanic Was Weeks From Closing His Shop — One Tax Credit Changed the Math

The Medicare enrollment event at the Richmond Public Library’s main branch on Hull Street was winding down on a Thursday afternoon in late February when I noticed Corey Kirby standing near the exit, holding a folded flyer and looking like a man who had walked into the wrong room. He was wearing a gray Henley with a faint grease stain near the cuff, and he had the particular stillness of someone trying very hard not to look worried.

I was there covering the event for American Relief — specifically, the question of how many working-age adults stumble into Medicare information sessions because they’re desperate for any kind of financial footing and don’t know where else to start. Corey Kirby, it turned out, was one of them. He was 53. Medicare was still 12 years away. But he’d seen the event listed on the library’s bulletin board and thought, maybe someone in there can help.

I introduced myself. He shook my hand with the kind of firm grip that comes from 23 years of working on engines. Within ten minutes, he was telling me about his shop.

KEY TAKEAWAY
Self-employed business owners who file as sole proprietors may qualify for the Section 199A Qualified Business Income (QBI) deduction — worth up to 20% of net business income — yet according to IRS data, a significant share of eligible filers either underclaim or miss it entirely.

A Business Built on Loyalty — and a Lease That Changed Everything

Corey Kirby has owned Kirby Auto Service, a four-bay shop off Midlothian Turnpike in Richmond, since 2018. Before that, he spent 15 years as a line mechanic at a dealership — good steady work, he said, until the dealership restructured and cut a third of its service staff. Rather than look for another employer, he scraped together $22,000 in savings, signed a commercial lease, and opened his own place.

For the first few years, the shop did well enough. Gross revenue in 2022 hit roughly $131,000. He had two part-time employees, a loyal base of customers who came back for every oil change and brake job, and a lease at $1,850 per month that he described as manageable.

Then the numbers started moving in the wrong direction. Gross revenue fell to approximately $114,000 in 2023, and then to around $97,000 in 2025. He attributed some of it to inflation squeezing his customers’ discretionary spending, some to a newer national chain that opened nearby, and some to the simple reality that running a one-man show means every sick day is a lost day of revenue.

Rent increase at January 2026 renewal

The lease renewal notice arrived in November 2025. His landlord was raising the monthly rate from $1,850 to $2,405 — a 30 percent increase, effective January 1, 2026. Corey told me he sat in his truck in the parking lot for nearly 20 minutes after reading it before he could go back inside and face the rest of the workday.

“When the landlord told me the new number, I sat in my truck for 20 minutes before I could go back inside. I kept doing the math in my head and every time I did, I came up short.”
— Corey Kirby, owner, Kirby Auto Service, Richmond, VA

He also lives with a roommate in a rented house about four miles from the shop — a cost-sharing arrangement he adopted specifically because his personal expenses needed to stay low while the business stabilized. His 2025 net business income, after operating expenses, came out to roughly $41,000. That’s the number his accountant had been working with for the last two tax seasons.

The Tax Returns He Filed Every Year — and What Was Missing From Them

Corey had been filing his taxes with the same local accountant since he opened the shop. He paid the fee, signed the forms, and moved on. He had no reason to question the process — it seemed professional, and he had no basis for comparison.

When I asked him how involved he was in reviewing what was actually on those returns, he laughed with the kind of quiet embarrassment that told me everything.

“I’ve been doing this for 23 years. I know every bolt on every American car made since 1990. But taxes? I just sign whatever my accountant puts in front of me. I always figured she knew what she was doing.”
— Corey Kirby

After our initial conversation at the library, I connected Corey with a volunteer at a Volunteer Income Tax Assistance (VITA) site — a free IRS-sponsored program that provides certified tax preparation for individuals generally earning under $67,000. The VITA volunteer, a retired CPA named Marcus who runs sessions out of a church on Semmes Avenue, agreed to review Corey’s prior two years of returns.

What Marcus found was not fraud or error, exactly. It was omission — the slow, expensive kind that compounds over years without anyone raising a flag.

What Corey Had Been Missing on His Tax Returns
1
Section 199A QBI Deduction — Sole proprietors may deduct up to 20% of qualified business income. On $41,000 net income, that’s a potential $8,200 deduction Corey had not been fully optimizing.

2
Self-Employed Health Insurance Deduction — Corey was paying approximately $4,800 per year in health insurance premiums out of pocket. Self-employed individuals can deduct 100% of this from gross income, per IRS Publication 535. It had been partially claimed, but not fully documented.

3
Business Use of Vehicle — Corey uses a personal pickup truck for supply runs, parts pickups, and occasional mobile service calls. He had never tracked the mileage formally. At the 2025 IRS standard mileage rate of 70 cents per mile, even 3,000 documented business miles represents a $2,100 deduction.

4
Home Office / Administrative Space Deduction — Corey handles bookkeeping and customer scheduling from a dedicated corner of his home. The IRS simplified method allows a deduction of $5 per square foot up to 300 square feet.

Total additional deductions Marcus identified across these categories: approximately $11,000 to $13,000. On a net income of $41,000, and depending on Corey’s effective federal tax rate, the estimated additional tax savings ranged from roughly $2,400 to $3,100. For a man whose rent had just increased by $555 a month, that number was not abstract.

⚠ IMPORTANT
The Section 199A QBI deduction has income thresholds that affect certain business types, but for most sole proprietors in service trades — including auto repair — the deduction is available without phase-out restrictions below the 2025 income threshold of $197,300 for single filers. Corey’s income fell well below that ceiling. Always verify current thresholds directly with the IRS or a qualified tax professional.

Finding Help in an Unexpected Place

The process of untangling two years of underclaimed deductions was not instant or painless. Marcus spent two sessions with Corey over three weeks — one reviewing the prior returns, one preparing amended documentation for 2024 and projecting forward into the 2025 filing.

Corey told me the hardest part wasn’t the paperwork. It was accepting that he had needed help and hadn’t known how to ask for it — or even that help of this specific kind existed at all.

“I didn’t even know the QBI deduction existed. I thought that was for bigger businesses, like contractors with employees. I run one shop. I didn’t think the IRS had anything for guys like me.”
— Corey Kirby

He also looked into whether his shop qualified for any Virginia-specific small business relief programs. The SBA’s Richmond District Office provides access to microloans and technical assistance through local partner organizations, and the Virginia Small Business Development Center network offers free consulting for business owners evaluating their financial position. Corey attended one session in March 2026 and said it was the first time in two years he’d talked to someone who didn’t immediately try to sell him something.

He hasn’t taken on any new debt. He’s still cautious about the microloan route — not opposed, just watching the numbers for another quarter before committing. His priority right now is the amended return and making sure the 2025 filing is structured correctly from the start.

Deduction Type Estimated Amount Previously Claimed?
Section 199A QBI (20% of net income) ~$8,200 Partially
Self-Employed Health Insurance ~$4,800 Partially
Business Vehicle Mileage ~$2,100 No
Home Office (Simplified Method) ~$900–$1,500 No
Total Additional Deductions ~$11,000–$13,000

Where Things Stand Now

When I last spoke with Corey in mid-March 2026, he had filed an amended 2024 return and was two weeks from submitting his 2025 taxes with the full suite of deductions properly documented. The projected refund for 2024 was approximately $1,900 — not a windfall, but meaningful. The 2025 filing was on track to reduce his tax liability by roughly $2,600 compared to what it would have been under his previous approach.

The shop is still under pressure. Revenue hasn’t recovered. The rent is still $2,405 a month. He told me he’s considered whether to renew again in 2027, or find a smaller space and scale back to two bays. Nothing is settled.

“It’s not going to save the shop by itself. But it buys me time. And right now, time is what I need.”
— Corey Kirby, March 2026

What stayed with me after our conversations was not the dollar amounts — though they matter — but the specific shape of the problem Corey represents. He is not someone who made reckless decisions. He opened a business. He paid his taxes. He signed what his accountant told him to sign. And for years, the system processed his filings without ever surfacing the full picture of what he was entitled to claim.

That’s not a dramatic failure. It’s a quiet one. The kind that doesn’t announce itself until a lease renewal letter lands in your mailbox and suddenly you’re running the math in a parking lot, trying to figure out if the thing you built can survive another year.

Corey Kirby is still figuring that out. But he’s doing it with better numbers than he had in February.

KEY TAKEAWAY
Self-employed sole proprietors earning under $197,300 (2025, single filers) may deduct up to 20% of qualified business income under Section 199A.

What Would You Do?

You’re a sole proprietor with a net business income of roughly $41,000, a commercial lease that just renewed 30% higher, and a VITA volunteer who tells you that you have approximately $11,000 in unclaimed deductions across the last two tax years. The April 15 deadline is six weeks away, and you’re also three months behind on quarterly estimated tax payments.
