“My Accountant Always Handled It” — A Visiting Nurse’s $22,400 Tax Surprise
Sandra had worked as a visiting nurse for over two decades. She filed her taxes every year without incident — her old accountant handled everything. When she sat down at my desk with a folder of 1099s and said “just tell me what to sign,” I already knew the number waiting for her was going to be a shock.
Key Takeaways
- A 1099-NEC means zero withholding — the full federal income tax and self-employment tax hits at filing unless you’ve been paying quarterly.
- Self-employment tax is 15.3% on net earnings, on top of income tax. For most 1099 workers, it’s the larger bill of the two.
- Business expenses reduce your taxable income — but only if you kept the documentation. Transportation receipts thrown away daily are deductions lost permanently.
- Meals eaten during a regular local workday are generally not deductible, even for self-employed workers.
- Underpaying estimated taxes triggers a penalty under IRC §6654 — added on top of what you already owe at filing.

1. Meet Sandra
Sandra is a visiting nurse in her 50s. She’s been doing this work for more than twenty years — traveling to patient homes, clocking ten-hour days, carrying her equipment on the bus and in taxis across the city. She’s good at her job. She takes it seriously. Her taxes? That was always someone else’s department.
Her previous accountant had set up quarterly estimated payments years ago. Four checks a year, $1,000 each. Sandra sent them without really knowing why, trusting the system was working. She assumed that if there were a problem, someone would have told her.
She came to my office in the middle of filing season. One 1099-NEC, $100,000 in home health services income. No other sources. She’d kept receipts for her nursing license renewal, a couple of uniform purchases, and dry cleaning. She handed me a thin folder and waited.
What she didn’t know — what nobody had ever walked her through — was what that single 1099-NEC actually meant for her tax bill.
2. What a 1099-NEC Actually Means at Tax Time
When you receive a W-2, your employer handles two things automatically: income tax withholding and their half of your Social Security and Medicare taxes. You never see that money. It’s gone before your paycheck is printed.
A 1099-NEC does neither of those things.
The core difference
A W-2 employee pays half of Social Security and Medicare — 7.65%. A self-employed worker on a 1099 pays both halves — 15.3%. That’s the self-employment (SE) tax under IRC §1401, and it applies before income tax even enters the picture.
On $100,000 in net self-employment income, the SE tax alone runs close to $14,000. Add federal income tax on top of that and you’re looking at a combined bill most 1099 workers aren’t prepared for — especially when they haven’t had it explained to them in plain terms.
Sandra had been earning around $100,000 a year for several years. Her $4,000 in annual estimated payments had covered just enough to avoid scrutiny in prior years — or perhaps her previous accountant had structured something differently. Either way, she arrived at my desk with no sense of the gap between what she’d paid and what she owed.
3. The Numbers Sandra Didn’t Know Were Coming
Here’s how Sandra’s tax return actually looked.
| Item | Amount |
|---|---|
| 1099-NEC gross income | $100,000 |
| Schedule C deductible expenses | ($800) |
| Net profit (Schedule C) | $99,200 |
| Self-employment tax (SE tax) | $14,000 |
| Less: ½ SE tax deduction (above-the-line) | ($7,000) |
| Adjusted Gross Income (AGI) | $92,200 |
| Standard deduction (single, 2026) | ($16,100) |
| Taxable income | $76,100 |
| Federal income tax | $11,500 |
| Total federal tax liability | $25,500 |
| Estimated payments made | ($4,000) |
| Balance due before penalty | $21,500 |
| Underpayment penalty (IRC §6654) | $900 |
| Total owed at filing | $22,400 |
SE tax alone — $14,000. That’s the bill that catches most 1099 workers off guard because it doesn’t appear anywhere on a pay stub. It exists only on Schedule SE, which most people never see until they’re sitting across from an accountant.
Important: SE tax is calculated on 92.35% of net self-employment earnings, not the full amount. This reflects the employer-side deduction built into the formula. The effective SE tax rate works out to approximately 14.13% of net profit.
Sandra went quiet when she saw the table. She’d assumed her estimated payments had her covered. $4,000 a year, four times a year — it felt like she was doing the right thing. Against a $25,500 tax liability, it barely made a dent.
4. The Receipts She Threw Away Every Day
Sandra took taxis to every patient visit. On a busy day she’d make four or five stops across the city, ten hours on her feet, taxis in and out. She never kept the receipts.
Transportation directly related to your work — travel between client locations, trips to supply vendors, mileage or fares tied to patient care — qualifies as an ordinary and necessary business expense under IRC §162. A self-employed visiting nurse traveling to patient homes is exactly the kind of worker this rule was written for.
What “No Receipt” Actually Costs
Without documentation, the expense doesn’t exist for tax purposes. IRS records requirements under §6001 mean that deductions need to be substantiated — amounts, dates, and business purpose. A rough estimate doesn’t qualify. “I took taxis constantly” doesn’t qualify. The receipt from Tuesday afternoon that Sandra threw in a trash can outside the patient’s building — that qualified.
On a conservative estimate, $25–$35 in taxi fares per working day over 220 days comes to roughly $5,500–$7,700 in potentially deductible transportation. Sandra couldn’t claim any of it.
What About Meals?
Sandra ate lunch out every day, usually between patient visits. She assumed this was deductible. It isn’t. Meals during a regular local workday — even long ones — are a personal expense under the tax code. Meal deductions for self-employed workers require a clear business purpose beyond simply needing to eat. “I was at work all day” doesn’t meet that standard.
Her license renewal fee ($150), uniforms ($350), and dry cleaning ($300) were all legitimate deductions. They added up to $800 total. That’s what made it onto Schedule C.
5. Why $4,000 in Quarterly Payments Wasn’t Enough
Sandra hadn’t chosen $1,000 per quarter randomly. Her old accountant had set it up. Something had worked well enough for years — or so it seemed. The actual liability, built on SE tax she’d never fully understood, had always been higher than $4,000.
Form 1040-ES exists to help self-employed workers calculate what they should be paying each quarter. The general rule: you need to pay at least 90% of the current year’s tax liability, or 100% of last year’s tax (110% if your AGI exceeded $150,000), to avoid the underpayment penalty under IRC §6654.
The safe harbor rule in plain terms
To avoid a penalty, your total estimated payments must cover at least what you owed last year — or 90% of what you’ll owe this year. For Sandra, that meant quarterly payments of roughly $6,375 per quarter, not $1,000.
Nobody had updated the calculation. Sandra kept sending the same four checks. The gap between what she paid and what she owed quietly compounded each year — and the penalty it triggered at filing was an additional $900 she hadn’t budgeted for.
6. What to Do Differently
- Confirm whether your income is reported on a 1099-NEC — if yes, no income tax or SE tax has been withheld.
- Calculate your estimated SE tax at the start of the year. Multiply expected net profit by 14.13% to get a rough SE tax figure.
- Set up quarterly estimated payments using Form 1040-ES — due April 15, June 16, September 15, and January 15.
- Keep every taxi or rideshare receipt on the day you receive it. Date, amount, and business destination are the three things you need.
- Save license renewal invoices, uniform receipts, and laundry receipts in a dedicated folder — digital or physical.
- Do not assume meals during your regular local workday are deductible. They generally are not.
- Ask your accountant to show you the Schedule SE calculation — not just the balance due. Understanding where the number comes from makes every future year easier to plan for.
EA Insight
Sandra isn’t unusual. Clients who’ve worked with the same accountant for years often arrive with no working knowledge of their own tax situation. They know the refund or the balance due. They don’t know how it was calculated or why. That’s not a criticism — it’s a natural result of fully delegating something complicated. The problem is that delegation without understanding leaves you blind to whether the setup is still working.
The taxi receipts are what stay with me from this case. She worked ten-hour days in the field, traveling constantly, and threw away documentation worth roughly $1,500 in tax savings every single year. It wasn’t laziness — nobody had ever told her those receipts were money. Once I walked through the Schedule C with her and showed her how each expense category connects to a line on her return, she pulled out her phone and downloaded a mileage-and-receipt tracking app before she left my office.
If you’re receiving 1099s and your quarterly payment amount hasn’t changed in two or more years, it’s worth a quick calculation. SE tax doesn’t stay static if your income grows, and neither does the gap between what you’ve been paying and what you actually owe.
EA Summary
Sandra’s $22,400 tax bill wasn’t a mistake — it was the accurate result of twenty years of 1099 income with SE tax she’d never fully accounted for. A 1099-NEC shifts the full payroll tax burden to the worker, and quarterly estimated payments need to be sized to that liability, not set and forgotten. The deductions she missed — documentation she threw away daily — would have reduced the bill by over $1,000, but only if she’d known to keep them.
Is Your Bookkeeping Built the Way the IRS Reads It?
If you’re a self-employed professional receiving 1099s, your books should map directly to Schedule C — so there are no surprises at filing. As an Enrolled Agent who handles bookkeeping for Schedule C businesses, I build records the way the IRS expects to see them.

What is self-employment tax and why is it so high?
Self-employment tax covers both the employee and employer portions of Social Security and Medicare — 12.4% and 2.9% respectively, for a combined rate of 15.3% under IRC §1401. W-2 employees split this with their employer and only pay 7.65%. Self-employed workers pay the full 15.3% themselves because they are both the employer and the employee.
Do I have to pay estimated taxes if I receive a 1099?
Generally yes. If you expect to owe at least $1,000 in federal taxes after subtracting withholding and refundable credits, you’re required to make quarterly estimated payments using Form 1040-ES. Failing to do so triggers an underpayment penalty under IRC §6654, even if you pay the full balance by the April filing deadline.
Can a visiting nurse deduct transportation expenses?
Yes — transportation between patient locations and to business-related destinations qualifies as an ordinary and necessary business expense under IRC §162. However, documentation is required under §6001: dates, amounts, and the business purpose of each trip. Taxis, rideshares, and public transit fares all qualify, but only with records to support them.
Are meals deductible for self-employed workers?
Rarely during a standard local workday. Meal deductions require a clear business purpose beyond personal sustenance. Workers traveling away from their tax home overnight may deduct 50% of meal costs under the travel expense rules, but eating lunch between patient visits in your home city does not meet the threshold.
How do I know if my quarterly estimated payments are enough?
The IRS safe harbor rule says your payments must cover at least 100% of last year’s tax liability (or 90% of this year’s), whichever is smaller. If your income is over $150,000, the prior-year safe harbor rises to 110%. Form 1040-ES includes a worksheet to help you calculate the correct quarterly amount.
