How Much Can I Take Out of My Physician Practice S-Corp?

Two constraints limit how much you can take out of your physician practice S-corp: a legal ceiling — your stock basis — and, for most practices, the tighter practical limit of your working capital reserve. That is at the heart of one of the most common questions from physician practice owners — and one of the least clearly answered anywhere: how much of the money sitting in my practice bank account can I actually take out?

The answer is not “all of it.” It is also not some vague percentage. There is a specific framework for calculating your monthly distribution capacity, and understanding it is the difference between running a financially stable practice and creating cash flow problems for yourself.

What’s the Difference Between S-Corp Distributions and Salary?

In an S-corp, you have two ways money flows from the practice to you personally:

W-2 Salary: Paid through payroll on a regular schedule. Subject to payroll taxes (Social Security and Medicare). Required by the IRS before any distributions are taken. The optimal salary amount is a separate calculation — covered in how much to pay yourself as a physician S-corp owner.

Distributions (K-1 income): Money pulled from the S-corp’s retained earnings above and beyond your salary. Not subject to payroll taxes. Taxed as ordinary income on your personal return via the K-1.

Distributions are not wages. They do not trigger payroll tax. But they are also not free money — they are your share of the practice’s after-tax profits, and taking them requires that the profits actually exist in the form of cash the practice can spare.

What Are the Two Constraints on S-Corp Distributions?

Constraint 1: Legal — Sufficient Basis

An S-corp shareholder can only take distributions up to their stock basis — roughly, the cumulative amount of income reported and taxes paid through the S-corp over time, minus prior distributions.

In practice, most physician practice owners who have been in business more than two or three years have adequate basis to support normal distributions. Basis problems typically arise when:

• The S-corp has had net losses that exceed the owner’s basis
• Prior distributions were taken in excess of basis (the excess is taxable as capital gain)

Your CPA should track your basis annually on a Schedule E workpaper. If you have never seen a basis calculation, ask for it — it is a critical number.

Constraint 2: Practical — Working Capital Reserve

This is the constraint that actually limits most physician practice distributions: the practice needs cash to operate.

Your practice has fixed monthly obligations regardless of collections:

• Payroll for staff
• Rent / lease payments
• Medical supplies and equipment payments
• Malpractice insurance premiums
• Software and billing systems
• Loan payments on equipment or build-out

If you pull cash out of the practice and then a large payroll hits, you have a problem. The distribution limit is not just “what the practice has earned” — it is “what the practice has earned minus what it needs to keep.”

What Is the Formula for Your Working Capital Reserve?

The standard working capital reserve for a physician practice:

Minimum reserve = 2 months of total fixed monthly operating expenses

This is your floor. The practice should never drop below this amount in its operating account regardless of how much you could theoretically distribute.

Example:

• Monthly payroll (staff + your salary): $28,000
• Rent: $4,500
• Malpractice insurance (monthly allocation): $1,800
• Supplies and other fixed costs: $3,200
• Total fixed monthly expenses: $37,500
• Minimum operating reserve: $75,000 (2 months)

Any cash in the practice above that $75,000 floor — after tax reserves are set aside — is distributable.

How Much Should You Reserve for Taxes Before Distributing?

Before calculating how much you can distribute, you need to account for the taxes you will owe on the income being distributed.

S-corp income is taxed at your personal rate, not the corporate rate. When the practice earns $50,000 in net income, that income is going to appear on your personal return whether you take the cash or not. The tax is owed regardless of distribution timing.

This means you need to hold a portion of practice income in reserve for taxes before counting anything as distributable:

Recommended tax reserve: 30–38% of K-1 income (depending on your marginal rate and state). For a full breakdown of the reserve percentages by income range and how to calculate your quarterly estimated payments, see the dedicated guide.

Example:

• Monthly K-1 income from practice (net after salary and expenses): $25,000
• Tax reserve at 35%: $8,750
• Available for distribution after tax reserve: $16,250

This is the amount you can move to your personal account without creating a cash crunch at tax time.

How Do You Calculate Your Monthly Distribution Capacity?

Putting it together:

Practice bank balance
  minus  Minimum operating reserve (2 months fixed expenses)
  minus  Tax reserve on undistributed K-1 income
  minus  Any upcoming large known expenses (equipment purchase, insurance renewal, etc.)
  equals  Distribution capacity this month

Full example:

That $44,000 is what can safely move to your personal account this month. Not $145,000. Not whatever the balance looked like before payroll.

When Should You Take Distributions?

Most physician practice owners take distributions monthly or quarterly. Monthly gives you more consistent personal income. Quarterly gives the practice more time to collect on outstanding claims before cash is pulled.

The right cadence depends on your practice’s collections cycle. If your average days to collection from payers is 35–45 days, taking a distribution on the 1st of every month means some of last month’s revenue is not yet collected. Monthly distributions work best when the practice has a healthy baseline balance above the operating reserve — not when it is running tight.

A practical approach: Set a recurring distribution on the 15th of each month, calculated based on collections through the end of the prior month minus the reserve calculation above. Run the calculation before every distribution, not on a fixed dollar amount.

What Mistakes Should You Avoid When Taking Distributions?

A few specific mistakes that create problems:

Sweeping the account: Pulling whatever is in the account at the end of the month without running the reserve calculation. This creates periodic cash crunches when large expenses hit and can leave you unable to make payroll.

Taking distributions before salary: The IRS requires that S-corp owner-employees receive a reasonable W-2 salary before taking any distributions. Taking distributions without payroll, or taking a disproportionately small salary relative to distributions, is the primary S-corp audit trigger.

Treating distributions as salary in disguise: Some physicians stop running payroll and just take distributions to avoid payroll taxes entirely. This is not a gray area — it is reclassified as wages on audit, with back payroll taxes, penalties, and interest.

Ignoring basis: Taking distributions in excess of your stock basis triggers capital gain recognition. If you have had loss years or have been in business a short time, your basis may be lower than expected.

The Right Mental Model

Think of the practice bank account as a reservoir, not a checking account. Water flows in from collections. Water flows out through payroll, operating expenses, tax reserves, and distributions. Your distribution is the amount you can draw from the reservoir without dropping below the operational floor.

The physicians who manage this well set a fixed monthly review: run the calculation, take the distribution, leave the reserves untouched. The ones who struggle treat the account balance as a personal ATM and are constantly surprised when the practice runs short.

The calculation is not complicated. Running it consistently — every month, before every distribution — is what makes the difference.
