You’ve done the hard part and built something from the ground up. Whether your business is two years in or a decade deep, you’ve proven your resilience, resourcefulness, and vision. But there’s one area that still causes tension for many women in business: estimated taxes.

At Insogna CPA, we work with women entrepreneurs across industries. From online coaches to boutique agency founders and eCommerce retailers who feel confident in so many areas of their business but admit that estimated taxes can feel…confusing at best, overwhelming at worst.

This guide is here to change that.

Our goal is to provide not just clarity, but calm. You deserve to feel both supported and empowered when it comes to managing your finances. So let’s take a breath, sit down together (figuratively, for now), and walk through what estimated taxes are, why they matter, and how you can manage them like the CEO you are.

What Are Estimated Taxes?

In short, estimated taxes are payments made throughout the year on income that isn’t subject to automatic withholding. Most W-2 employees have taxes withheld from each paycheck but as a business owner, the IRS expects you to handle that responsibility yourself.

You’re likely required to make estimated payments if you receive income from:

• Self-employment (as a sole proprietor or LLC)
  
  
• An S-Corporation (as a shareholder taking distributions)
  
  
• Investment income
  
  
• Rental properties
  
  
• Contract or freelance work
  
  
• Side businesses or secondary income streams
  
  

Essentially, if you earn income where no one is withholding taxes on your behalf, it’s up to you to pay those taxes throughout the year.

Estimated taxes typically cover:

• Income tax
  
  
• Self-employment tax (Social Security + Medicare)
  
  
• Additional taxes, like the Net Investment Income Tax or Additional Medicare Tax for high earners
  
  

And while the system might feel like it was built for a different generation of business owners, it’s one we can work with strategically.

Why Estimated Taxes Matter for Women Entrepreneurs

Let’s talk about why this matters beyond just avoiding IRS penalties.

Estimated taxes reflect how you’re building and managing your business wealth. They help you stay in tune with your profitability, cash flow, and long-term financial planning. When you understand and prepare for these payments, you’re not just avoiding stress. You’re making empowered decisions rooted in data, not guesswork.

As a woman entrepreneur, your income may not look the same each month. You might:

• Have high-revenue launches followed by quieter quarters
  
  
• Take time off for personal goals or family
  
  
• Scale rapidly after hiring or restructuring
  
  
• Receive variable project-based or retainer income
  
  

All of these make flat, fixed quarterly tax payments feel like a bad fit and that’s where personalized guidance from a small business CPA in Austin makes all the difference.

When Are Estimated Taxes Due?

The IRS sets four quarterly deadlines each year:

If a deadline falls on a weekend or holiday, the payment is due on the next business day.

Missing a payment, especially multiple payments, can trigger underpayment penalties. More importantly, it can disrupt your cash flow when the full tax bill hits at year-end.

How Much Should You Pay?

The amount you owe depends on your income, business structure, deductions, and personal financial situation. But here’s how we approach it:

1. Safe Harbor Method

This is a go-to for avoiding penalties. You qualify for “safe harbor” protection if you pay:

• 90% of your current-year tax liability, or
  
  
• 100% of last year’s tax liability (110% if your income was over $150,000)
  
  

This method is helpful if your income is steady or if you’re unsure how your current year will play out.

2. Quarterly Actuals Method

For more variable income (think: course creators, consultants, seasonal business owners), we recommend calculating quarterly payments based on real-time income and expenses. That means reviewing your books quarterly, updating your tax projection, and adjusting your payment accordingly.

This method gives you flexibility and accuracy. And when you partner with an experienced CPA firm in Austin, Texas, you’re not doing those calculations alone. We’re in it with you.

How Do You Pay Estimated Taxes?

There are several easy options:

• IRS Direct Pay – Pay directly from your bank account at gov/payments
  
• EFTPS (Electronic Federal Tax Payment System) – A secure government system for recurring payments
  
  
• Via check – Using IRS Form 1040-ES (less popular but still available)
  
  
• Through tax preparation software – If your CPA integrates payments with your tax prep tools
  
  

And here in Texas? No state income tax. But if you operate in multiple states or have nexus elsewhere, a licensed CPA or tax advisor in Austin can guide you through additional state payment obligations.

The Penalty for Underpayment And Why You Shouldn’t Panic

Here’s the part most entrepreneurs worry about: What if I underpay?

The IRS will typically charge an underpayment penalty, which is essentially interest on what you should have paid. It’s not always a huge dollar amount ut it’s avoidable.

We’ve seen clients come to us after a year of rapid growth with unexpected penalties from missing quarterly payments. Our approach? Prevention, not correction.

Working with an Austin, TX accountant means we keep an eye on your earnings and provide proactive alerts when your payments need to shift. No more scrambling at tax time.

When Your Income Isn’t Consistent (Which Is…Often)

Let’s be real, business doesn’t pay you on a steady salary. You have months when you’re flush with cash and others where you’re reinvesting heavily or waiting on client payments.

This is where traditional tax strategies don’t always serve women entrepreneurs. At Insogna CPA, we design cash flow-aware tax strategies that match the ebb and flow of your income.

That might include:

• Adjusting estimated tax payments mid-year
  
  
• Aligning payments with product launches or large invoices
  
  
• Setting aside a fixed percentage of monthly profit
  
  
• Building a quarterly review cadence to assess tax impact
  
  

Your finances should support your lifestyle and business, not surprise you when you least expect it.

A Note on FBAR Filing

If you hold more than $10,000 in foreign financial accounts, even temporarily, you may need to file an FBAR (Foreign Bank Account Report). Many women with online businesses or international investments don’t realize they qualify.

This isn’t directly tied to estimated taxes, but it’s one more way to ensure full compliance and avoid penalties. A certified public accountant near you can confirm whether FBAR applies and ensure it’s filed accurately.
