Estimate only
This is a planning tool, not tax advice. Quarterly estimates ignore retirement contributions, healthcare deductions, credits, state-specific rules, and net investment income tax. Confirm figures with a CPA or tax professional before paying.
Set the quarterly payment aside automatically
Move the recommended amount into a separate tax savings account each month so you never get caught short in April.

Open toolHow this quarterly tax estimator works
Solo therapists are taxed as self-employed individuals, which means federal income tax, state income tax (where applicable), and a 15.3% self-employment tax all apply to net practice profit. Estimating quarterly prevents an April surprise and keeps you under the IRS safe-harbor thresholds.
Enter your expected annual net profit, your state tax rate, and filing status. The estimator calculates SE tax on 92.35% of net profit, layers in progressive federal brackets after the standard deduction and half-SE-tax adjustment, and divides the total by four.
Use it for situations like
- Planning cash reserves at the start of a new quarter.
- Checking whether your current set-aside amount matches the IRS safe-harbor rule.
- Stress-testing a raise or rate increase before you finalize it.
- Comparing the impact of a state move on quarterly tax owed.
FAQ
Questions therapists ask before using this calculator
Do therapists really have to pay quarterly taxes?
If you expect to owe at least $1,000 in tax after subtracting withholding and refundable credits, the IRS requires you to pay estimated taxes quarterly as a self-employed individual. Most solo therapists meet that threshold within their first year.
How is self-employment tax calculated for therapists?
Self-employment tax is 15.3% applied to 92.35% of your net practice earnings. It funds Social Security (12.4%) and Medicare (2.9%), and you can deduct half of it when figuring your federal income tax.
When are quarterly tax payments due?
Federal quarterly estimates are due April 15, June 15, September 15, and January 15 of the following year. State deadlines vary; check your state Department of Revenue for the exact schedule.
How do I lower my quarterly tax estimate?
Contribute to a SEP-IRA, Solo 401(k), or HSA, claim legitimate home office and business deductions, and track health insurance premiums for the self-employed. Each item reduces your taxable profit before SE tax is applied.
Is this estimate a substitute for a CPA?
No. This estimator helps you plan cash flow and avoid surprises, but it ignores retirement contributions, healthcare deductions, state-specific rules, and credits. Pair it with a year-end review from a tax professional.
