The New Midwifery Practice Tax Calendar: Every Deadline You Cannot Miss
A practical 2026 tax deadline calendar for new midwifery practices, covering quarterly estimates, payroll, and annual filings with actionable steps.
Starting a midwifery practice brings a steep learning curve, and taxes are often the steepest part. Missing a deadline can trigger penalties that eat into your hard-earned revenue. This guide lays out every tax deadline you cannot miss in 2026, with concrete dates, realistic cost ranges, and steps you can take this week to stay ahead.
Quarterly Estimated Tax Payments
As a self-employed midwife or practice owner, you must pay taxes on income as you earn it. The IRS requires quarterly estimated payments if you expect to owe at least $1,000 in tax for the year. For 2026, the deadlines are:
- Q1 (Jan 1 - Mar 31): April 15, 2026
- Q2 (Apr 1 - May 31): June 15, 2026
- Q3 (Jun 1 - Aug 31): September 15, 2026
- Q4 (Sep 1 - Dec 31): January 15, 2027
How to calculate: Use Form 1040-ES. A common method is to pay 100% of last year’s tax liability (or 110% if your adjusted gross income was over $150,000). For a new practice, estimate your annual net income and multiply by the self-employment tax rate (15.3%) plus your income tax bracket. For example, if you expect $80,000 net profit, set aside roughly $15,000 to $20,000 for federal taxes.
Action this week: Open a separate business savings account and transfer 25% of every client payment into it. This creates a buffer for quarterly payments.
Payroll Tax Deadlines (If You Have Employees)
If you hire a receptionist, nurse-midwife, or billing specialist, you must handle payroll taxes. Deadlines vary by deposit schedule:
- Monthly depositors: Pay employment taxes by the 15th of the following month.
- Semi-weekly depositors: Pay within 3 business days after payday (for paydays on Wed, Thu, Fri) or within 2 business days (for paydays on Sat, Sun, Mon, Tue).
Forms to file:
- Form 941 (Quarterly Federal Tax Return): Due April 30, July 31, October 31, and January 31.
- Form 940 (Annual Federal Unemployment Tax): Due January 31, 2027.
- W-2s and W-3: Provide to employees by January 31, 2027; file with Social Security by the same date.
Costs: Payroll services range from $40 to $150 per month, depending on headcount. Using a service like Gusto or ADP can prevent late deposit penalties.
Action this week: If you have employees, set up payroll software that automatically calculates and schedules deposits. If you are solo, skip this section.
Annual Business Filings
Your practice structure determines which annual forms you must file:
- Sole proprietorship: Report income on Schedule C with your personal return. No separate business return.
- LLC (single-member): Same as sole proprietorship for federal taxes, but check your state for annual reports (fees $50 to $300).
- S-corp: File Form 1120-S by March 15, 2026 (or March 15, 2027 for the 2026 tax year).
- Partnership: File Form 1065 by March 15, 2026.
Action this week: Confirm your business structure and note the annual report due date for your state. Mark it on your calendar.
State and Local Taxes
Most states require quarterly or annual filings for:
- State income tax: Often aligns with federal deadlines, but check your state’s department of revenue.
- Sales tax: If you sell products like breast pumps or supplements, you may need to collect and remit sales tax. Deadlines vary (monthly, quarterly, or annually).
- State payroll taxes: Usually filed quarterly with the state workforce agency.
Costs: State filing fees range from $0 to $500 annually, depending on your state and entity type.
Action this week: Visit your state’s revenue website and download a tax calendar. Many states offer email reminders.
Tax Extension and Final Filing Deadlines
If you cannot file your personal or business return by the regular deadline, you can request an automatic 6-month extension:
- Personal return (Form 1040): Due April 15, 2026; extension to October 15, 2026.
- S-corp or partnership: Due March 15, 2026; extension to September 15, 2026.
Important: An extension to file is not an extension to pay. You must still pay any tax owed by the original deadline to avoid penalties.
Action this week: If you know you will need an extension, file Form 4868 (for individuals) or Form 7004 (for businesses) by the original due date. Do this even if you cannot pay in full.

FAQ
What if I miss a quarterly estimated payment? The IRS charges a penalty based on the amount owed and the number of days late. The rate is currently around 8% per year, compounded daily. File the payment as soon as possible to minimize the penalty.
Can I deduct health insurance premiums as a midwife? Yes, if you are self-employed and not eligible for an employer-sponsored plan, you can deduct premiums for yourself, your spouse, and dependents. This deduction reduces your adjusted gross income.
Do I need to charge sales tax on prenatal visits? Generally, medical services are exempt from sales tax, but products like vitamins or birth supplies may be taxable. Check your state’s rules. When in doubt, consult a tax professional.
Should I hire a CPA or use tax software? For a new practice, software like QuickBooks Self-Employed ($25 to $50 per month) can handle estimates and Schedule C. If you have employees or an S-corp, a CPA ($500 to $2,000 for annual filing) is worth the cost to avoid errors.
The Bottom Line
Tax deadlines for a new midwifery practice are non-negotiable. Missing one can cost you hundreds in penalties and stress. Start by setting up a dedicated tax savings account, mark every date from this article on your calendar, and consider automating payroll if you have staff. If you are uncertain, spend $200 to $500 on a consultation with a tax professional who works with healthcare practices. That upfront cost can save you thousands later. Stay organized, and your practice will thrive without tax surprises.
