If you own a therapy practice in California, one of the first questions you may ask is:

"How much of this money is actually mine?"

That is a better question than simply looking at the balance in your business bank account.

Some of that cash may need to cover operating expenses.

Some may be available to pay you.

And some may already have another job: taxes.

There is no single tax-saving percentage that works for every therapist. Your actual tax obligation depends on your business profit, filing status, other household income, entity structure, deductions, tax credits, and how much tax is already being paid through withholding or estimated payments.

But you can still build a simple system so tax time does not become a cash-flow emergency.

Start With Profit, Not Deposits

A common mistake is to set aside taxes based only on the money hitting the bank.

Your deposits are not necessarily the same as your taxable business profit.

For example:

Your practice collects $15,000 during the month.

That does not automatically mean you are taxed on $15,000.

Your business may also have expenses such as:

• office rent
• software
• payment-processing fees
• professional insurance
• continuing education
• payroll
• contractor costs
• bookkeeping
• marketing

Taxes are generally driven much more by your taxable income than by your gross bank deposits.

That is one reason clean bookkeeping matters.

If your Profit & Loss is unreliable, your tax planning is built on a shaky number.

So What Percentage Should I Save?

Many business owners like having a percentage they can automatically move into a separate savings account.

That can be a useful cash-management habit.

But the percentage should be treated as a planning tool, not as your actual tax calculation.

One therapist may need to reserve substantially more than another therapist earning the same practice revenue because their overall tax situations are different.

For example, your tax picture can change based on:

• whether you are a sole proprietor or S corporation
• your spouse's income
• other W-2 or investment income
• your deductions
• retirement contributions
• health insurance
• dependents and credits
• prior-year tax
• California income tax
• federal income tax
• self-employment tax or payroll tax structure

A tax reserve should therefore be reviewed periodically instead of choosing one percentage forever and hoping it works.

Quarterly Taxes Are Prepayments

Estimated tax payments are not an extra tax.

They are simply a way of paying tax during the year instead of waiting until you file the return.

At the federal level, taxpayers who are required to make estimated payments generally use current-year tax or prior-year tax rules to determine how much needs to be prepaid.

California has its own estimated-tax rules and payment schedule.

That means the amount your tax professional tells you to pay may not be divided into four perfectly equal payments.

Do not assume "quarterly" always means 25% every three months.

California Is Especially Important Here

California estimated tax payments do not follow the same equal-quarter pattern many business owners expect.

The state generally allocates the required annual payment using:

• 30% for the first installment
• 40% for the second installment
• 0% for the third installment
• 30% for the fourth installment

Your actual requirement can vary based on your circumstances, so use the payment instructions provided with your tax projection or return.

The practical takeaway is simple:

Do not copy your federal payment amount and assume California works exactly the same way.

It does not.

Separate "Tax Money" From "Available Money"

One of the easiest ways to accidentally overspend is to keep all business cash in one checking account.

Your bank balance might say:

$40,000

But if:

$10,000 is being held for taxes,

$8,000 is needed for upcoming payroll,

and $5,000 is your normal operating cushion,

you do not really have $40,000 available to spend.

A separate tax savings account creates a useful boundary.

Money goes in.

It stays there.

You stop mentally counting it as spendable cash.

Simple system. Big difference.

A Better Monthly Tax Routine

Instead of thinking about taxes only four times a year, build tax planning into your monthly financial routine.

Each month, review:

1. Year-to-Date Profit

How much profit has the practice actually generated?

2. Tax Savings

How much have you already moved into your tax account?

3. Estimated Payments

How much federal and California estimated tax has already been paid?

4. Changes in Income

Is the practice earning significantly more or less than expected?

5. Other Household Income

Has anything changed outside the practice that could affect the tax projection?

This is especially useful for growing practices.

A tax estimate that worked when your practice earned $80,000 may not work when the practice starts earning $140,000.

What If My Income Changes During the Year?

Then your tax plan should change too.

Your estimated payments are not something you calculate once in January and ignore until next year.

If your practice grows quickly, your tax reserve may need to increase.

If profit drops, your estimated tax requirement may change.

If you elect S corporation status, start payroll, make a large retirement contribution, or have another major financial change, your projection may also need to be revisited.

Your bookkeeping gives you the information needed to see those changes early.

Should I Pay Taxes Directly From My Business Account?

For a sole proprietor or single-member LLC taxed as a sole proprietorship, federal and state individual income taxes are generally personal taxes rather than business expenses on the Profit & Loss.

That does not mean the business cannot provide the cash.

It means the accounting treatment matters.

For S corporation owners, the bookkeeping and tax-payment treatment can also differ depending on what is being paid.

If you are unsure, ask your bookkeeper or tax professional before categorizing tax payments inside QuickBooks.

The Goal Is Not to Guess Perfectly

The goal is to create enough visibility that you are not surprised.

You should be able to answer:

• How much have I earned?
• How much have I already saved?
• How much have I already paid?
• Is my current tax reserve still reasonable?
• Do I need an updated projection?

That is much more useful than choosing a random percentage from social media.

The Easy Peasy Takeaway

Your tax savings account is not just a place to park money.

It is part of your practice's cash-flow system.

Start with reliable bookkeeping.

Know your year-to-date profit.

Use your actual tax projection to determine what needs to be paid.

Then build a consistent habit of moving tax money out of your operating account before you accidentally treat it as spendable cash.

Because the question is not just:

"How much money is in my bank account?"

The better question is:

"How much of it can I actually keep?"

Frequently Asked Questions

Do therapists have to pay quarterly taxes?

Many self-employed practice owners and business owners do, especially when sufficient tax is not being withheld elsewhere. The exact requirement depends on the taxpayer's overall situation.

Should I just save 30% for taxes?

A percentage can be useful as a cash-management shortcut, but it should not replace an actual tax projection. The right amount varies widely.

Are California estimated taxes the same as federal estimated taxes?

No. California has its own rules and payment schedule.

Should my tax savings account show up as an expense in QuickBooks?

Moving money from checking to savings is normally a transfer between bank accounts, not an expense. The treatment of the actual tax payment depends on the entity and type of tax.
