Bookkeeping and Taxes for a Private Therapy Practice

When therapists ask how to start a private therapy practice, the money admin usually comes down to three things: open a business checking account before your first client pays you, record income and expenses as they happen rather than reconstructing them later, and know which tax dates apply to you so nothing arrives as a surprise. None of this is intellectually difficult. It is simply much easier to set up in your first month than to untangle in your first April. Nothing here is tax or legal advice, and your own accountant should confirm how any of it applies to your situation.

Why does a separate business bank account matter?

A separate account matters because it becomes the record of your practice year without you doing anything extra. Every deposit is practice income and every withdrawal is a practice expense, which means your bookkeeping is mostly a matter of categorizing a statement rather than sifting a personal account for the charges that belonged to the business.

There is a second reason. If you have formed an LLC, PLLC or PC at the state level, keeping business and personal money in one place works against the separation the entity is meant to create. How much that matters in your state, and for your structure, is a question for your attorney. The practical point stands either way: one account for the practice, one card for the practice, and your record keeping shrinks by most of its volume.

You will usually be asked for an EIN when you open the account. An EIN is a free identification number issued by the IRS that identifies your business for tax purposes, and most therapists want one anyway so that a Social Security number is not sitting on insurance and vendor paperwork. It is a different thing from your NPI, which identifies you in healthcare transactions and does nothing for your taxes.

What counts as a business expense in a therapy practice?

Broadly, costs that exist because the practice exists. The categories that show up on almost every solo practice's books look like this:

• Malpractice insurance
• License renewal and state board fees
• Your EHR or practice management subscription
• Directory listings such as Psychology Today
• A practice phone line or answering service
• Continuing education, consultation and clinical supervision
• Office rent, or the home office portion if you qualify for it
• Website, domain and email hosting
• Card processing fees and bank charges
• Professional association dues
• Legal, accounting and administrative support

What any of these is worth to you on a return depends on your structure, your state and your overall picture, so check specifics with your tax professional rather than with a colleague's group chat. The part that is entirely in your hands is capture. An expense you never recorded is an expense you cannot claim, and receipts photographed at the point of purchase are the only version of this that survives a busy caseload.

How do I track income when insurance pays late?

Track the claim and the payment as two separate events, because in an insurance-based practice they are often weeks apart. The session happens, the claim goes out, the remittance arrives later and sometimes for a different amount than you expected. If your bookkeeping only records deposits, you have a cash record but no way to see which sessions were never paid for.

A simple monthly habit covers it: reconcile what your EHR says you billed against what actually landed in the account, and put anything unmatched on a follow-up list. Denials and claims that quietly stalled look identical to a slow month until somebody looks. This is also where your contract effective dates matter, as we covered in the post on credentialing: being credentialed with a payer and being loaded as in-network under a signed fee schedule are two different milestones, and billing before the effective date is a common reason early claims come back unpaid.

How does self-employment tax work for a solo therapist?

If you practice as a sole proprietor or a single-member LLC, nobody is withholding tax from your income. You are responsible for income tax plus self-employment tax, which covers both the employee and employer shares of Social Security and Medicare that a salaried job would have split with you. You pay it in installments across the year rather than in one lump at filing.

The system that works for most solo practice owners is mechanical rather than disciplined:

1. Open a second savings account purely for tax.
2. Move a fixed share of every deposit into it on the day the deposit arrives. Your accountant can help you set the percentage based on your expected income and state.
3. Pay your estimated payments out of that account only.
4. Leave whatever is left over after filing where it is, as the float for next year.

Estimated payments are due several times a year on dates the IRS sets, and many states run their own parallel schedule. Get the current dates from your accountant or the IRS directly and put them in the same calendar you use for sessions. Add your entity's annual state filing and your business license renewal while you are there, since those are covered in our post on business licenses and tend to arrive without a reminder.

Does forming an LLC change my taxes?

Not by itself. Forming an entity happens at the state level and is a legal structure decision; how that entity is taxed is a separate election. A single-member LLC is commonly taxed in the same way as a sole proprietorship unless you choose otherwise, and some practice owners later elect S corporation treatment once income reaches a level where it makes sense. Which states allow licensed professionals to use which structures also varies, so your state board and your attorney are the right first calls. We have written separately about LLC versus sole proprietor for therapists if you are at that decision now.

Where does administrative help fit?

A virtual assistant for therapists is not your bookkeeper and not your accountant. What support does affect is the quality of what reaches them. A trained assistant can handle billing support, send invoices and statements, follow up on outstanding claims, keep receipts and vendor documents filed where you can find them, and give you a written summary of what was completed each month. That is the difference between a tidy handoff to your accountant and a shoebox.

At Assistant to the Therapist, our assistants are trained specifically for mental health practices, which matters here because the rhythm of claims, remittances and client balances is not the same as general business invoicing. The clinical and financial decisions stay yours. The chasing does not have to.

Common questions

Do I need accounting software, or is a spreadsheet enough?

A spreadsheet is genuinely enough for a small solo practice with one income stream and a modest expense list, provided you update it monthly. Software earns its cost when you want bank feeds, receipt capture and categorization done for you, or when you have multiple payers and a growing client balance ledger. Ask your accountant what they prefer to receive, because that answer often decides it.

Should I hire a bookkeeper or an accountant first?

Most solo practice owners start with an accountant for the annual return and the estimated payment figures, then add bookkeeping support if the monthly categorizing is the part that slips. If you are already behind by several months, a bookkeeper who understands small healthcare practices will usually get you current faster than you will get yourself current between sessions.

How long should I keep practice financial records?

Retention periods for tax records and for clinical records are different rules with different timeframes, and clinical retention is set by your state and your board rather than by the IRS. Keep them in separate systems so you are never making a storage decision about a chart based on a tax rule. Confirm both periods with your own advisor and your licensing board.

What should I do if I missed an estimated payment?

Contact your accountant rather than waiting for the next deadline. There are mechanisms for catching up, and the cost of a late or short payment is generally smaller than the cost of ignoring it for several more months. This is one of the few pieces of practice admin where acting on an imperfect number beats waiting for a perfect one.
