When you work 1099 in Florida, no one withholds taxes for you and no one shares the cost of your health insurance. The biggest surprise for new contractors is the self-employment tax: 15.3% on net earnings — 12.4% for Social Security on the first $184,500 of 2026 self-employment income, plus 2.9% for Medicare with no ceiling. That is on top of regular federal income tax, and it lands four times a year as estimated payments.
The good news for Floridians: there is no state income tax and no separate state return, so your entire tax life as a 1099 contractor is federal. This guide covers the 2026 numbers, the quarterly schedule, and how to handle the health coverage you now have to buy yourself.

The Core Thing New Contractors Get Wrong
The most common mistake is treating a 1099 rate like a W-2 salary. A $70,000 contract is not equivalent to a $70,000 job. As a contractor you owe the full 15.3% self-employment tax that an employee splits 50/50 with an employer, you fund your own health insurance with after-tax-feeling dollars, and you get no employer retirement match. A useful rule of thumb is to set aside 25–30% of every payment for federal taxes before you touch it. Because Florida has no income tax, that reserve is purely for the IRS — but it still needs to be there.
2026 Self-Employment Tax, Step by Step
- Net your income on Schedule C. Gross receipts minus legitimate business expenses equals net profit.
- Apply the SE tax base. You pay SE tax on 92.35% of net profit. The 12.4% Social Security portion applies up to the 2026 wage base of $184,500; the 2.9% Medicare portion applies to all of it.
- Deduct half of SE tax. One-half of your self-employment tax is an above-the-line deduction on Schedule 1, which reduces your income tax (not your SE tax).
- Watch the Additional Medicare Tax. High earners owe an extra 0.9% Medicare tax on earnings above $200,000 (single) or $250,000 (married filing jointly).
| 2026 Item | Rate / Amount |
|---|---|
| Social Security portion of SE tax | 12.4% up to $184,500 |
| Medicare portion of SE tax | 2.9% (no cap) |
| Additional Medicare Tax | 0.9% over $200k single / $250k MFJ |
| Deductible share of SE tax | 50% |
2026 Quarterly Estimated Tax Due Dates
- Q1 (Jan–Mar income): April 15, 2026
- Q2 (Apr–May income): June 16, 2026
- Q3 (Jun–Aug income): September 15, 2026
- Q4 (Sep–Dec income): January 15, 2027
A safe-harbor strategy avoids underpayment penalties: pay at least 100% of last year's total tax (110% if your prior-year AGI topped $150,000) across the four installments, even if you ultimately owe more. For contractors with lumpy income, this is usually the most practical approach.
Contractors in income-tax states often have to make state estimated payments too, sometimes on a different schedule. In Florida there is no personal income tax and no state estimated payment — you make federal estimates only. That is one fewer deadline and one fewer agency to satisfy.
Your Health Insurance as a 1099 Contractor
Without an employer plan, your main options are the ACA marketplace (where most contractors qualify for income-based premium tax credits), a spouse's employer plan, or COBRA from a prior job. Whatever you pay in premiums is generally deductible under the self-employed health insurance deduction — 100% above the line — as long as you have net profit and no access to subsidized employer coverage. Note that this premium deduction lowers income tax but not the 15.3% SE tax.
An HSA-qualified high-deductible plan is worth a hard look. A 2026 HDHP must carry a minimum deductible of $1,700 (self-only) or $3,400 (family), and pairing it with an HSA lets you deduct up to $4,400 (self-only) or $8,750 (family) on top of your premiums. For a healthy contractor, the lower premium plus the extra deduction often beats a richer plan on after-tax cost. See our FSA vs. HSA tax guide for how the accounts compare.
Common Mistakes to Avoid
- Not reserving for taxes. Set aside 25–30% of each payment for the IRS from day one.
- Skipping quarterly payments. Waiting until April triggers underpayment penalties.
- Forgetting the half-SE-tax deduction. It is easy money left on the table.
- Going uninsured to save cash. One ER visit erases years of saved premiums, and marketplace subsidies often make coverage cheaper than contractors expect.

Deductions That Shrink Your Tax Base
Every legitimate Schedule C expense does double duty for a 1099 contractor: it lowers both your income tax and the 15.3% self-employment tax, because SE tax is calculated on net profit. Common ones include the home-office deduction, business mileage at the IRS standard rate, equipment and software, professional licenses, and the business portion of your phone and internet. On top of those, the Qualified Business Income (QBI) deduction can shave up to 20% off your qualified pass-through income at the federal level — though it reduces income tax only, not SE tax. For Floridians, careful expense tracking is the highest-return habit you can build, since there is no state income tax and the federal bill (income tax plus SE tax) is the entire cost of being self-employed. Keep contemporaneous records: a mileage log, a dedicated business account, and digital receipts turn defensible deductions into real reductions in your quarterly estimated payments.
