May 27, 2026

14% of the U.S. workforce are self-employed workers.

For those workers, there’s no magic button when it comes to taxes as a self-employed professional. There’s no change in entity structure that drastically reshapes your tax liability on its own. Tax planning when you’re self-employed is about looking ahead and preparing for what is coming.

We asked Tim Owens, CPA, for their top tax planning tips for self-employed professionals in California.

Here are their tax planning tips:

Always look ahead when it comes to taxes.
Make quarterly estimated tax payments rather than waiting until you file.
Planning for retirement? Consider a SEP IRA that lets your contribution scale with income.
In California, not every federal tax break applies at the state level. Plan accordingly.
Filing as an LLC is not a tax plan. Understand what it does and does not do for you.
Evaluate every tax decision in the context of your full picture.
Factor in healthcare coverage.
Think five years ahead if you’re thinking about an S-Corporation.

Whether you are a freelancer, consultant, or small business owner, tax planning in California comes with its own set of challenges. Read on for a closer look at each of Tim’s tax planning tips.

1. Always look ahead when it comes to taxes.

Most tax concerns, even if they cannot be completely eliminated, become less of a burden when identified and planned for well in advance. While there are options to reduce taxes once the new year hits, the truth is that planning ahead gives you more flexibility and control over your outcomes.

2. Make quarterly estimated tax payments rather than waiting until you file.

Making quarterly payments or structural changes to your business needs to happen well in advance of actually filing a tax return. Waiting until year-end limits your options and can result in penalties for underpayment.

The IRS requires quarterly estimated payments if you expect to owe $1,000 or more in taxes.

3. Planning for retirement? Consider a SEP IRA.

A SEP IRA (Simplified Employee Pension Individual Retirement Account) is a tax-advantaged retirement account designed for self-employed individuals and small business owners.

SEP IRAs are a great option if you’re self employed. In 2026, you can contribute 25% of your compensation, up to $72,000. Compare that to the $7,500 contribution limit for traditional and Roth IRAs. Unlike a traditional IRA, you can contribute more when you have higher profits thus reducing your taxable income for the year.

For lighter years, it’s also a blessing in disguise. Contribution limits flex up or down based on what you earn and you’re limited to a reasonable level. With affordability being a concern in today’s economy, a SEP IRA can help keep you honest about your cash flow by keeping your contribution limit lower.

4. In California, not every federal tax break applies at the state level. Plan accordingly.

California operates in a sort of alternate tax universe to the federal, where some of the planning carries over, but there are tweaks that lead to different expectations.

For a lot of businesses, tax planning for California is less about taking advantage of specific ways to reduce tax at the state level, and more about understanding that many of the better tax breaks do not flow through to the state return.

Here are a couple of examples where this comes up:

Tips income. Someone in an industry like photography, where tips are part of their pay, may have an opportunity to reduce their federal taxes by claiming some of those tips as an income reduction. California does not adhere to that.
California does not allow for bonus depreciation. A major asset purchase can give a significant advantage on the federal return, only to be adjusted on the state side for less of an impact. For the next five to seven years, the depreciation schedule will be out of sync as California catches up. Not a problem on its own, but something to keep in mind.

5. Filing as an LLC is not a tax plan. Understand what it does and does not do for you.

A lot of people have a misguided idea that having your business in an LLC creates some tax advantages, but that’s not the case, at least not by itself. But what it does do is it forces an additional $800 minimum in taxes to the state of California every year.

6. Evaluate every tax decision in the context of your full picture.

Saving money in one area can cost you more in another.

When tackling any tax or business plan in California, everything needs to be done in balance. The goal is to make sure you are not saving $500 in one area only to spend $1,000 somewhere else.

This kind of whole-picture thinking is especially important when weighing business structure changes, retirement contributions, and healthcare costs at the same time.

7. Factor in healthcare coverage.

Having healthcare coverage is required in California. If you do not have it, you will pay a penalty on your state return. From a cash flow perspective, there are times when the raw numbers suggest it would cost less to pay the penalty than to pay for health insurance. But that leaves you exposed to potentially significant medical bills.

Whatever coverage you carry, make sure the appropriate deductions are built into your tax plan.

8. Think five years ahead if you’re thinking about an S-Corporation.

How you structure your business today should reflect where you expect it to be in five years, not where it is right now. For many self-employed professionals, that conversation eventually leads to the question of an S-Corporation.

There is no guaranteed dollar amount where an S-Corporation makes sense, but a general rule of thumb is that when net profits are consistently over $80,000, it is worth starting the conversation about a possible switch.

Filing as an S-Corporation comes with a number of compliance standards that need to be followed. It all comes down to the big picture and where you see the business heading.

FAQs About Tax Planning for Self-Employed Professionals

What happens if I miss a quarterly estimated tax payment?

The IRS charges a penalty on the unpaid amount, and the longer you wait, the more it grows. California adds its own penalty on top of that.

If an LLC is not a tax plan, what is it good for?

It separates your personal assets from your business liabilities, which is a legitimate reason to form one. Just know that in California it comes with an $800 minimum annual tax.

When does it make sense to switch to an S-Corporation?

A general rule of thumb is when net profits are consistently above $80,000. At that point, the potential payroll tax savings may outweigh the added compliance costs. Have the conversation before you hit that threshold, not after.

Can I deduct my health insurance premiums as a self-employed professional?

In most cases, yes. Self-employed individuals can generally deduct 100% of their health insurance premiums without itemizing, as long as you were not eligible for coverage through an employer or a spouse’s plan during that period. Your advisor can confirm whether your situation qualifies.

How much can I contribute to a SEP IRA?

For 2026, you can contribute up to 25% of your net self-employment income, with a maximum of $72,000. That is nearly ten times the $7,500 limit for a traditional IRA, making it one of the most powerful retirement savings tools available to self-employed professionals.

What are the biggest differences between California and federal tax rules for the self-employed?

A few of the most common ones: California does not allow bonus depreciation, does not follow all federal income exclusions, and has its own penalty for not carrying health insurance. Many federal tax breaks simply do not carry over to the state return, which is why California tax planning often needs to be treated as a separate conversation.

Tax Planning Is an Ongoing Process

There may be no magic button to help you with your tax planning, but there is also no need for them if you approach it properly. You won’t need shortcuts if you stay ahead of your tax burden and build a strategy around your full picture.
