Quarterly Taxes: How to Calculate, Save, and Pay Without Panic

If you’re self-employed or run a small business, quarterly taxes are part of the deal—yet most owners don’t fully understand how they work. And honestly, the IRS doesn’t make it intuitive.

Good news: quarterly taxes don’t have to be stressful or surprising.
With the right system, they become predictable and manageable.

Below is a clear, no-nonsense method to calculate your estimated taxes, save for them consistently, and pay them on time—without scrambling every quarter.


1. Understand What Quarterly Taxes Actually Are

Quarterly taxes (estimated taxes) are payments you make to the IRS four times per year:

  • April 15

  • June 15

  • September 15

  • January 15

The purpose is simple: the IRS expects you to pay taxes as you earn income—not once a year.

Who needs to pay?
Generally, anyone expecting to owe $1,000 or more in taxes for the year who doesn’t have taxes withheld from a paycheck.

This includes:

  • freelancers

  • LLC owners

  • contractors

  • side-hustlers

  • business owners with profit

  • anyone paid on 1099

  • S-Corp owners (for non-payroll income)


2. A Simple Way to Estimate What You Owe

You don’t need complex formulas.

Use this practical rule of thumb:

Set aside 20–30% of your profit.

  • Lower income / high deductions: ~20%

  • Higher income / few deductions: ~25–30%

Profit, not revenue, is the key number.
Profit = Revenue – Expenses.

If you made $8,000 in profit this month:

  • 20% savings = $1,600

  • 25% savings = $2,000

  • 30% savings = $2,400

This method keeps you ahead of the IRS instead of behind.


3. Make a Habit of Saving From Each Deposit

Business owners get in trouble when they wait until quarter-end to gather cash.

Instead:

  • Set aside a percentage from every deposit

  • Move it into a separate tax savings account

  • Avoid mixing it with operating expenses

  • Treat it as “untouchable”

This ensures January, April, June, and September don’t hit your cash flow like a brick.


4. What About S-Corp Owners?

If you’re an S-Corp owner taking payroll:

  • Your W-2 salary includes tax withholding

  • Your distribution income does not

  • You may still owe estimated taxes on the non-salary portion

A simple method:
Use your accountant or payroll system to estimate whether withholding is covering enough.
If not—quarterly payments make up the difference.


5. How to Actually Make the Payments

The IRS prefers online payments. Here are the options:

IRS Direct Pay

Uses your bank account (free).

EFTPS (Electronic Federal Tax Payment System)

Good for recurring payments.

QuickBooks or tax software

Some allow direct quarterly payment scheduling.

State quarterly taxes

Don’t forget your state may require its own payments.


6. Signs You Need Professional Help

Quarterly taxes get more complicated when:

  • income fluctuates dramatically

  • you have employees

  • you file as an S-Corp

  • you have multiple businesses

  • you receive multiple 1099s

  • you’re behind on previous estimates

If you’re unsure whether your estimates are high, low, or on track, an accountant can help you avoid underpayment penalties—or paying more than necessary.


Final Thoughts

Quarterly taxes can be completely manageable once you set up a simple rhythm: calculate a percentage of your profit, save as you go, and pay on time. With the right system, you can avoid stress, surprises, and last-minute scrambles.
