Most NYC early intervention therapists work as 1099 independent contractors and have to manage their own taxes. This is manageable if you understand the structure. It becomes stressful and expensive only if you ignore it until April. Here is a practical guide to what you owe, when you owe it, and how to reduce your bill legally.
The four taxes you pay as a 1099 NYC EI therapist
1. Federal income tax: Applied to your net self-employment income (revenue minus deductible expenses) at your marginal bracket. For most NYC EI therapists earning $50,000 to $80,000, this is the 22% bracket after standard deduction.
2. Self-employment (SE) tax: 15.3% on the first $160,200 of net self-employment income in 2026. This covers Social Security (12.4%) and Medicare (2.9%). You pay both the employer and employee share because you are both. The good news: you can deduct half of SE tax from your gross income before calculating income tax.
3. New York State income tax: New York taxes income at progressive rates up to 10.9% for high earners. For an NYC EI therapist earning $55,000 net, the effective NY state rate is approximately 5.5 to 6%.
4. NYC income tax: New York City charges an additional local income tax of 3.078 to 3.876% for residents. If you live in NYC (not just work there), this applies to you.
Combined effective tax rate for an NYC EI therapist earning $60,000 net: approximately 38 to 42% including all four taxes. Set aside at least 35% of every agency payment to cover taxes, more if you are a high earner.
Quarterly estimated tax dates for 2026
- April 15, 2026: Q1 estimated payment (January 1 to March 31)
- June 16, 2026: Q2 estimated payment (April 1 to May 31)
- September 15, 2026: Q3 estimated payment (June 1 to August 31)
- January 15, 2027: Q4 estimated payment (September 1 to December 31)
To avoid an underpayment penalty, pay either 90% of your 2026 tax liability or 100% of your 2025 liability (110% if your 2025 AGI exceeded $150,000), whichever is smaller. If this is your first year of self-employment income, the 100% of prior year method only works if you had meaningful tax liability last year.
Key deductions for NYC EI therapists
Mileage: Track every business mile. The 2026 IRS rate is 70 cents per mile. Use an app like MileIQ or Stride to log automatically. An NYC EI therapist driving 10,000 business miles per year saves $7,000 in taxable income.
Supplies and materials: Therapy toys, books, assessment tools, apps with a clinical purpose. Keep receipts.
Phone: If you use your personal phone for work calls, scheduling, and documentation, a percentage of your monthly bill is deductible. Document the business use percentage.
Continuing education: All CEUs, conferences, workshops, and professional journal subscriptions related to speech-language pathology or EI practice.
Licensing and professional fees: NYS license renewal, ASHA dues, liability insurance premiums.
Health insurance: The self-employed health insurance deduction lets you deduct 100% of premiums for yourself and your family, directly reducing taxable income (not just as an itemized deduction). This is one of the most valuable deductions available to 1099 therapists.
Retirement contributions: Contributing to a SEP-IRA lets you deduct up to 25% of net self-employment income, up to $69,000 in 2026. This is the single most powerful tax reduction tool available to solo self-employed therapists. Every dollar contributed reduces both your income tax and your adjusted gross income used for other calculations.
Should you form an LLC or S-Corp?
For most NYC EI therapists earning under $80,000 net from EI work alone, a simple Schedule C (no entity) is fine. At higher income levels, an S-Corp can reduce self-employment tax by allowing you to take part of your income as a distribution rather than wages. This involves more administrative cost and complexity. Consult a CPA who works with self-employed healthcare providers before making this decision.
