Nobody tells you about relief vet taxes when you sign your first shift agreement. You get paid the full day rate, nothing withheld, and then April rolls around, and you owe a number that doesn’t feel real. The math is not the problem. The problem is that the whole system changed when you stopped being a W-2 employee, and nobody handed you a manual. This guide covers what you actually owe in 2026, what you can write off, and how quarterly payments work so you’re not scrambling at year-end.
Most relief vets are independent contractors. You get a 1099-NEC at year-end, not a W-2. Some platforms and clinics do hire relief vets as W-2 employees, so if you’re not sure which you are, check your contract or ask whoever processes your payments. It matters more than most people realize.
Here’s the practical difference:
Most relief vets are 1099. That’s what the rest of this guide covers.
This one surprises almost everyone in the first year. When you’re a W-2 employee, Social Security and Medicare (FICA) are split between you and your employer. Each side pays 7.65%. Go 1099, and there’s no employer to split it with. You pay both halves: 15.3% total on net self-employment income up to $176,100 in 2026, then 2.9% above that.
You do get a partial offset: half of what you pay in self-employment tax is deductible from your gross income on your federal return. It doesn’t reduce your bill dollar-for-dollar, but it takes some of the edge off.
Relief vet income gets taxed at ordinary income rates. The 2026 brackets for single filers, straight from the IRS:
| Taxable income (single filer) | Rate |
|---|---|
| Up to $12,400 | 10% |
| $12,401 – $50,400 | 12% |
| $50,401 – $105,700 | 22% |
| $105,701 – $201,775 | 24% |
| $201,776 – $256,225 | 32% |
| $256,226 – $640,600 | 35% |
| Over $640,600 | 37% |
One thing worth understanding: these are marginal rates. Landing in the 24% bracket doesn’t mean you pay 24% on everything. You pay 10% on the first chunk, 12% on the next, and so on up. Most relief vets in full-time schedules end up in the 22–24% federal bracket. Stack self-employment tax on top, and you’re realistically looking at 35–40% combined before state taxes. That’s the number to build your reserve around.
Nine states have no income tax at all: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. Every other state takes a cut, ranging from 2–3% in some places up to over 13% in California. If you pick up shifts across state lines, each state where you earn income may expect a return. Filing thresholds vary, so it’s worth keeping a record of where you actually worked throughout the year.
Here’s where relief vet taxes start working in your favor. W-2 employees can’t deduct work expenses under current federal law. As a self-employed contractor, you can deduct legitimate business costs before your taxable income is calculated. For a DVM running a full relief schedule, those add up fast.
Malpractice insurance
If you carry your own professional liability policy, the full premium is deductible.
Continuing education
CE credits, conference fees, registration costs. Travel and hotel for CE trips also count. Meals are 50% deductible when you’re traveling for business.
License fees & DEA registration
Annual renewal fees for every state license you hold and your DEA number. Multi-state licensing is common in relief work, and each fee counts.
Professional memberships
AVMA dues, state VMA dues, specialty organization memberships. All deductible.
Business travel & mileage
The 2026 IRS mileage rate is 72.5 cents per mile. Set up MileIQ or Everlance and let it run. At that rate, 10,000 miles is $7,250 you would otherwise leave on the table. For multi-day regional travel, transportation, lodging, and 50% of meals can all be deductible.
Equipment & supplies
Stethoscopes, otoscopes, scrubs, a laptop or tablet you use for work, software subscriptions. Anything you own and bring to shifts.
Health insurance premiums
Self-employed DVMs can deduct 100% of health, dental, and vision premiums for themselves and their family. One catch: you can’t claim this if you’re eligible for coverage through a spouse’s employer plan.
Home office
If you have a dedicated space at home used exclusively for work (scheduling, records, admin), it qualifies. The simplified method is $5 per square foot, up to 300 sq ft. The room can’t be a guest bedroom on weekends; the IRS is strict about the exclusivity requirement.
As a self-employed contractor, you can open a SEP-IRA and contribute up to 25% of your net self-employment income. The 2026 ceiling is $72,000. Every dollar you contribute comes straight off your taxable income.
What this looks like in practice
A relief vet with $180,000 in net self-employment income who puts $45,000 into a SEP-IRA is only taxed on $135,000. At a 24% bracket, that’s roughly $10,000–$12,000 saved in one move. The contribution deadline is your tax filing deadline, including extensions, potentially as late as October, so you have time to figure out the right number after you see your final income.

The IRS doesn’t wait until April for its money. As a 1099 contractor, you’re expected to pay as you earn, four times a year. Miss those payments and owe more than $1,000 at filing time, and you’ll pay an underpayment penalty on top of the actual bill. Payments go straight to IRS Direct Pay. No account needed, no fee.
| Quarter | Period covered | Due date |
|---|---|---|
| Q1 | Jan 1 – Mar 31 | April 15, 2026 |
| Q2 | Apr 1 – May 31 | June 16, 2026 |
| Q3 | Jun 1 – Aug 31 | September 15, 2026 |
| Q4 | Sep 1 – Dec 31 | January 15, 2027 |
The system that actually works: every time a shift payment hits your account, move 30–35% into a separate savings account you don’t touch. Pay the IRS from that account each quarter. California, New York, or other high-tax states? Use 38–40% instead. Whatever’s left after that is yours, no surprises.
Some staffing platforms and clinic groups hire relief vets as W-2 employees instead of contractors. The tax picture looks different depending on which side you’re on:
| 1099 | W-2 | |
|---|---|---|
| Tax withholding | You handle it quarterly | Employer handles it |
| FICA (Social Security + Medicare) | You pay both halves (15.3%) | Split with employer (7.65% each) |
| Business deductions | Full access | Very limited under current law |
| Filing complexity | Higher | Lower |
| Gross rate quoted | Usually higher (no employer overhead built in) | Reflects employer costs |
There’s no universally right answer here. At higher income levels, the deductions available to 1099 contractors usually offset the self-employment tax burden, sometimes by a lot. For vets earlier in their careers, or those who’d rather not think about quarterly payments, W-2 may net out similarly after running the actual numbers. For current compensation data by market, the Relief Vet Pay Rates page breaks it down by region.
Relief vet taxes aren’t complicated once you have a system. The hard part is the first year, before you know what to expect. Set aside 30–35% from every payment, make quarterly payments on time, keep a mileage log, and open a SEP-IRA if your income supports it. That covers most of it. The ongoing admin, once the system is running, is maybe two hours a quarter.

Relief vets working as 1099 independent contractors pay three types of tax: self-employment tax (15.3% on net income up to $176,100 in 2026, then 2.9% above that), federal income tax at ordinary income rates (10%–37% depending on taxable income), and state income tax where applicable. Because there is no employer withholding, relief vets pay these on a quarterly estimated schedule rather than through paycheck deductions.
A good starting point is 30–35% of every shift payment. That covers federal income tax and self-employment tax for most relief vets with a small buffer. In high-income-tax states like California or New York, 38–40% is safer. The exact number depends on your total income, deductions, retirement contributions, and filing status.
The four quarterly due dates for 2026 are: April 15 (Q1), June 16 (Q2), September 15 (Q3), and January 15, 2027 (Q4). Payments can be made at irs.gov/payments using Direct Pay. No account required, no fee.
Common deductions for 1099 relief vets include malpractice insurance premiums, continuing education costs, state license and DEA fees, professional memberships, business mileage (72.5 cents per mile in 2026), equipment and clinical supplies, health insurance premiums, home office expenses, and SEP-IRA contributions. These deductions are available to self-employed contractors but not to W-2 employees under current tax law.
Yes, if you receive 1099 income as an independent contractor. Schedule C is where self-employment income and business deductions are reported. Self-employment tax is calculated on Schedule SE, which attaches to your 1040.
The 2026 SEP-IRA limit is up to 25% of net self-employment income, with a maximum of $72,000. Contributions are fully tax-deductible and reduce your taxable income dollar-for-dollar. The contribution deadline is your tax filing deadline, including extensions. For self-employed filers who request an extension, that can be as late as October 2027.
It depends on income level and how much you value simplicity. As a 1099 contractor, you pay both halves of FICA (15.3%) but gain access to deductions W-2 employees can’t touch: mileage, equipment, health insurance premiums, SEP-IRA contributions. At higher income levels, those deductions usually offset the self-employment tax. A W-2 is simpler, and the employer covers half of FICA, but you give up most access to deductions under current law.
A single-member LLC is taxed exactly like a sole proprietor by default. It doesn’t change anything on its own. An S-corp election can lower self-employment taxes at higher income levels by splitting income into salary and distributions. Still, the cost of running payroll through an S-corp usually only makes sense above roughly $80,000–$100,000 in annual relief income. Worth researching carefully before making the move.
