Have you ever quietly built your financial life around something that wasn’t actually yours to keep? A shift differential, a bonus, an overtime line that showed up reliably enough that you stopped thinking of it as extra?

I thought about that question for days after I sat down with Robert Kirby at a folding table inside a community center on Nebraska Avenue in Tampa. A caseworker there had reached out to our publication in early March 2026, describing a situation she called “the kind that doesn’t fit into any single box.” She was right.

The Man Behind the Budget Spreadsheet

Robert Kirby is 36 years old. He has worked as a custodian for a Tampa-area public school district for nine years, long enough to earn step increases that brought his base salary to approximately $52,400 a year. His wife, Dana, died of a cardiac event in December 2021, leaving him to raise two teenagers largely alone. Both kids are now in college out of state — one in Georgia, one in North Carolina — and Robert lives by himself in a two-bedroom rental in Seminole Heights that costs $1,480 a month.

On paper, $52,400 sounds workable for a single person. In practice, Robert told me, it has never been the actual number he ran his life on. “For the last four years, I was averaging about $67,000 with overtime,” he said. “Nights, weekends, summer deep-cleans. I always figured if I needed to slow down, I could just cut back a little. I didn’t think the option would just disappear.”

In September 2025, the school district restructured its custodial shift assignments as part of a broader budget response to declining state per-pupil funding. Overtime slots were consolidated, prioritized by seniority in a different classification than Robert held. Almost overnight, he went from roughly $5,600 a month take-home to just under $3,900.

A Loan Signed Out of Loyalty, Not Math

The overtime loss would have been painful on its own. What made 2025 genuinely destabilizing was something Robert had set in motion two years earlier, in the spring of 2023.

His late wife Dana had a younger brother, Marcus, who was trying to consolidate some credit card debt and needed a cosigner to qualify for a personal installment loan of $19,500 through a regional lender. Robert agreed. “Marcus is family,” Robert told me, leaning forward slightly. “Dana would’ve wanted me to help him. I didn’t think twice about it, honestly. He had a job, he had income. I thought I was just a formality on the paperwork.”

Marcus made payments through most of 2023 and into early 2024. Then, in June 2024, Marcus lost his job at a logistics company and stopped paying entirely. By November 2024, the lender had charged off the remaining balance — approximately $17,200 — and reported both Marcus and Robert to the credit bureaus. Robert’s credit score, which had been around 718, dropped to 641.

“I found out the loan was in default from a collections letter, not from Marcus. That’s what hurt. He never called me. I had to hear it from a piece of mail.”

The credit hit was bad. What Robert didn’t anticipate was the tax dimension that followed.

The 1099-C He Didn’t Know Was Coming

In January 2026, Robert received a Form 1099-C in the mail from the lender. Under IRS rules on cancellation of debt, when a lender forgives or charges off a debt, the canceled amount is generally treated as taxable income for the borrower — or in this case, the cosigner who was also legally responsible. The form listed $17,200 as canceled debt income.

Robert had never encountered a 1099-C before. He didn’t know what it was. He set it aside, thinking it was junk mail, and only brought it to the community center caseworker in February 2026 when he was gathering documents for tax preparation assistance. “She looked at it and her face changed,” he told me. “That’s when I knew something was wrong.”

⚠ IMPORTANT
When a lender cancels or charges off a debt you cosigned, the IRS may treat the forgiven amount as ordinary income — even if you never received the money and even if the primary borrower was the one who defaulted. According to the IRS Publication 4681, there are exceptions, including insolvency, but they must be claimed correctly using Form 982. Missing this can result in significant unexpected tax liability.

The caseworker helped Robert understand that the $17,200 from the 1099-C would likely be added to his 2025 gross income. Combined with his actual earnings — base salary plus the overtime he still received in the first eight months of 2025 — his total reportable income for the year came to roughly $78,600. That pushed him into a higher effective tax bracket for a portion of his income and eliminated his eligibility for several credits he had claimed in prior years. His estimated additional federal tax liability came to approximately $4,300.

“I didn’t earn that $17,000,” Robert said. “I never saw a dollar of it. Marcus spent it. But I owe taxes on it. That’s what I keep trying to explain to people and they look at me like I’m confused.”

Health Costs and the Quiet Math of Falling Behind

The overtime loss and the tax bill are the headline problems. But when I pressed Robert on what the day-to-day actually feels like, he kept coming back to health insurance.

The school district offers employer-sponsored health coverage. Robert’s monthly premium contribution for a single-person plan was $287 through mid-2025. In October 2025, the district shifted to a new carrier and Robert’s monthly contribution increased to $334 — a $47 monthly jump, or $564 more per year. That’s a relatively small number in isolation.

KEY TAKEAWAY
Robert lost roughly $1,217 per month in take-home pay when overtime ended. At the same time, his health premium rose $47/month, his tax liability grew by an estimated $4,300, and a collections account was actively damaging his credit. Each problem was manageable alone. Together, they landed simultaneously.

“It’s not that any one thing is going to destroy me,” Robert said. “It’s that they all happened at once and I had no cushion. I had savings for emergencies, but an emergency to me was like, a car repair. Not three different systems all breaking down in the same year.”

He looked into whether he might qualify for SNAP benefits after the overtime ended. At $52,400 in base salary as a single-person household, he falls above Florida’s gross income threshold for SNAP, which is set at 200% of the federal poverty level — approximately $29,160 per year for a single adult in 2025–2026. He doesn’t qualify, and he knows it. “I’m not looking for a handout,” he said. “I just wanted to know what existed.”

Exhausted But Not Defeated — Mostly

By the time the community center connected him with a volunteer tax preparer in late February 2026, there was some partial relief in sight. The preparer identified that Robert may qualify for insolvency exclusion under IRS rules, which could allow him to exclude some or all of the 1099-C income if his liabilities exceeded his assets at the time the debt was canceled. The caseworker was helping him document that case when I met him in early March.

Where Robert’s Situation Stands — March 2026
1
Tax situation pending — Volunteer preparer working to apply insolvency exclusion on Form 982, which could reduce or eliminate the $4,300 estimated additional liability.

2
Collections account active — The lender sold the charged-off debt to a collections agency. Robert has received two letters and has not yet responded or negotiated.

3
No overtime path visible — The district restructuring appears permanent. Robert is weighing a second job but says exhaustion makes it hard to commit.

4
Budget restructured — Robert cut his monthly spending by approximately $340, primarily by eliminating a storage unit ($95/mo), a streaming bundle, and reducing grocery spending.

The outcome isn’t a redemption story, not yet. When I asked Robert what he wished he had done differently, he was quiet for a moment. “I wish I had understood what cosigning actually meant,” he finally said. “Not the concept — I understood the concept. I mean what it feels like when it goes wrong and you’re the one who has to fix it.”

He paused, then added: “Dana would’ve told me not to do it. She was always the practical one. I think I did it partly because I felt like I owed something to her family. That’s not a financial reason. That’s an emotional reason. And now I’m paying for it financially.”

“I’m not broken. I’m just tired. There’s a difference. Tired means you can still get up tomorrow.”
— Robert Kirby, Tampa, FL, March 2026

As I drove back across the Howard Frankland Bridge that afternoon, I kept thinking about the phrase Robert had used: an emotional reason with financial consequences. It’s the kind of sentence that sounds like a cautionary headline, but lived from the inside, it’s just grief and loyalty and a signature on a piece of paper. Robert Kirby is not reckless. He is not a cautionary tale in the tidy sense. He is a man doing nine years of honest work, trying to stay connected to the family he lost, and discovering that those two things don’t always protect each other.

The tax preparer will file before April 15. The collections account will eventually need a response. And Robert will keep showing up to work at 5:45 in the morning, which he has done, without overtime, every single day since September.

Frequently Asked Questions

What is a 1099-C form and why would a cosigner receive one?

A Form 1099-C is issued by a lender when it cancels or charges off a debt. According to IRS Topic 431, a cosigner who is legally responsible for a loan can receive a 1099-C if the debt is forgiven or written off, even if the primary borrower was the one who defaulted. The canceled amount is generally counted as taxable income.
Can a cosigner avoid paying taxes on a canceled debt they never received?

Possibly. The IRS allows an insolvency exclusion under Internal Revenue Code Section 108, which can reduce or eliminate the taxable amount if the taxpayer’s total liabilities exceeded total assets at the time of cancellation. This must be claimed using IRS Form 982.
Does losing overtime pay affect your SNAP eligibility in Florida?

SNAP eligibility in Florida is based on gross household income. For a single-person household in 2025–2026, the gross income limit is approximately 200% of the federal poverty level, or roughly $29,160 per year, according to USDA FNS eligibility guidelines. A single adult earning $52,400 in base salary would not qualify regardless of overtime changes.
How does a loan default by a cosigned borrower affect your credit score?

When a primary borrower defaults on a cosigned loan, the lender reports the missed payments and eventual charge-off on the cosigner’s credit report as well. This can significantly lower a cosigner’s credit score — in Robert’s case, from approximately 718 to 641 — and the collections account can remain on the credit report for up to seven years under the Fair Credit Reporting Act.
What happens to employer health insurance premiums if your income drops?

Employer-sponsored health premiums are generally set by the employer and do not automatically decrease if an employee’s income drops. Under most group health plans, the employee’s contribution is a fixed monthly amount regardless of overtime. Employees who lose enough income may become eligible for ACA marketplace coverage during a Special Enrollment Period in some circumstances.
