How Much Money Should I Set Aside For Business Taxes?

Are you scrambling to pay taxes every April? You’re not alone. Many business owners make money but forget to plan for the IRS.

How to Avoid a Tax Season Panic and Build a Year-Round Tax Savings System

If your tax bill catches you off guard every year, you’re far from alone. “I’ve got a lot of net income in my business, but where’s the cash?”—That’s what a business owner told me just last week after finding out they owed thousands to the IRS. The problem? They hadn’t been making quarterly tax payments or setting aside reserves. Their net income looked great, but they didn’t have the liquidity to match.

For many business owners, taxes feel like a once-a-year scramble. But the truth is, taxes are a year-round commitment. The IRS doesn’t care if you’re surprised—they expect their share. That’s why creating a proactive, repeatable tax-saving system is one of the smartest financial moves you can make.

Why Year-Round Tax Planning Matters

It’s no secret: taxes are one of your biggest expenses. As the saying goes, “Death and taxes are the only certainties in life.” If you’re self-employed or running a small business, you’re expected to pay estimated taxes quarterly. But many people wait until the end of the year—when it’s already too late to do anything about it.

An Intuit study found that 73% of business owners feel unprepared for tax season. That’s not due to lack of effort—it’s due to lack of systems. The good news? You can fix this with just a few simple changes.

Start With the Basics: Know Your Tax Type

Are you a sole proprietor, an LLC, or an S Corp? Your structure determines your tax responsibilities. Sole proprietors and LLC owners pay self-employment tax plus income tax. S Corp owners are typically paid through payroll and have to deal with W-2 withholdings and business returns. And if you’re a C Corp, you’re looking at corporate tax rates, plus possible dividend taxes.

A good rule of thumb:

  • Sole Proprietors/LLCs: Set aside 25–30% of your net income
  • S Corps: Plan for 15–20% of total net income

Use last year’s return as a benchmark.

Build a Monthly Habit Around Savings

Once you have an idea of your effective tax rate, it’s time to put that into practice. Every month, calculate your net income (revenue minus expenses), and then set aside a fixed percentage—based on your structure—into a completely separate tax savings account.

For example, if you had $50,000 in net income this month and your tax rate is 25%, you’d move $12,500 into a dedicated tax account. Keep that money separate. Treat it like it’s already gone.

Some business owners use revenue as the base instead of net income. That’s okay too—just make sure you adjust your percentage down.

“If you’re using revenue, not profit, cut your [effective] tax rate in half to avoid over-saving and squeezing cash unnecessarily.”

You can automate transfers or make it a monthly task—whatever works best to keep you consistent.

Track It, Review It, Adjust It

Create a simple Google Sheet or Excel file to track monthly net income and apply your chosen percentage. Over time, as your business grows or changes, revisit your estimates. Partnering with a bookkeeper or accounting advisor can help refine your strategy.

As Xero noted in a recent report, businesses that automate their tax savings are twice as likely to avoid underpayment penalties.

“We’re not just trying to avoid taxes—we’re trying to avoid surprises.”

Watch Out for Common Mistakes

One of the most common issues? Applying the tax rate to revenue instead of net income. It’s a simple mistake, but it can throw off your entire plan. Also, don’t forget about other tax obligations—state tax, payroll tax, and sales tax. Each comes with its own rules and thresholds, and they often hit business owners when they least expect it.

Relying on last-minute cash to make your tax payment is another dangerous pattern.

“If your tax bill depends on your next big client deposit, you’re already in a dangerous cycle.”

Don’t fund a year-long tax obligation with a single last-minute check.

Your Action Plan

Step one: Choose your tax percentage based on last year’s return or a safe estimate.

Step two: Apply that to your net income every month.

Step three: Move that amount into a separate tax savings account. Modern banks make it easy to open new accounts—it takes minutes.

Finally, schedule a quarterly review. Look back at the last three months, adjust your estimates, and course correct. Even if you’re behind, starting now gets you one step closer to being ready for tax season—without the panic.

Final Thought

Creating a tax savings system isn’t just about discipline—it’s about freedom. When tax season rolls around, you won’t be crossing your fingers and hoping the numbers work out. You’ll already have the cash ready to go. And that peace of mind? It’s worth every penny.

“Planning for taxes isn’t exciting—but neither is getting caught off guard. Build the habit now, and thank yourself later.”

Here’s to a more prepared, sustainable, and profitable 2025.
