Estimated Tax Payments For Small Business: How To Calculate Your Quarterly Payments
Let's get real about estimated tax payments for small business - one of the most misunderstood (and often overlooked) parts of running a business. As a CPA who's worked with hundreds of entrepreneurs, I've noticed that even the most successful business owners often struggle with this aspect of their finances (ESPECIALLY as their business grows and they have a breakout year). So let's break it down!
Ever wonder why you get hit with a massive tax bill in April? Here's the reality: if you're not making estimated tax payments throughout the year, you're essentially letting that tax liability build up month after month.
Think of it like a credit card balance - ignore it for a year, and suddenly you're facing a number that makes you want to cry. That's exactly what happens when you don't make quarterly tax payments. Instead of paying your taxes in manageable chunks throughout the year, you're left with one big lump sum that can seriously impact your cash flow (and extra penalties that the IRS has added on because you missed your quarterly payments!) .
Who Needs to Pay Estimated Taxes?
If you're self-employed, a business owner, or earn income that isn't subject to withholding (like investment income or rental income), you probably need to pay estimated taxes. The IRS expects you to pay taxes on your income as you earn it throughout the year, not just on April 15th.
Let's put this in perspective: When you work as a W2 employee, your employer handles all your tax obligations throughout the year. They withhold a portion of each paycheck for federal income tax, Social Security, and Medicare, then send it directly to the government. This is why most employees either get a refund or owe a small amount when they file their taxes - they've been paying their tax bill in small chunks all year long.
But as a business owner, you don't have an employer withholding taxes for you. Instead, you're responsible for both the employer and employee portions of these taxes. This means you need to step into that employer role for yourself and create a system for setting aside and paying taxes regularly.
The IRS designed estimated tax payments to mirror the regular withholding that happens with W2 employment - it's their way of making sure self-employed individuals stay on track with their tax obligations just like employees do.
When Do You Need to Start Paying?
Generally, you need to make estimated tax payments if you expect to owe $1,000 or more in taxes when you file your return. These payments include:
Your income tax
Self-employment tax (which covers your Social Security and Medicare contributions)
Any other applicable taxes
The quarterly due dates follow a slightly unusual schedule:
Q1: April 15 (for income earned January-March)
Q2: June 15 (for income earned April-May)
Q3: September 15 (for income earned June-August)
Q4: January 15 (for income earned September-December)
How Are The Payments Actually Calculated?
Here's where things get complex - and why so many business owners get tripped up (this stuff is HARD!). Your estimated tax payments need to account for your total tax situation, not just your business income.
Here's what really goes into the calculation:
Calculate your total expected taxable income for the year from ALL sources:
Your business profit (revenue minus expenses)
PS If you aren’t keeping up with this already, you need https://learn.christybowie.com/profitway-dashboard
Your spouse's income (if filing jointly)
Any other income (investments, rental properties, side gigs)
Minus adjustments to income (retirement contributions, HSA contributions, etc.)
Determine your tax bracket
This depends on your total household income and filing status
Remember: being in a 22% tax bracket doesn't mean you pay 22% on all your income!
Calculate self-employment tax on your business profit
Currently 15.3% on net profit (12.4% for Social Security up to the wage base limit, 2.9% for Medicare with no limit)
You can deduct half of this on your tax return
Factor in any credits or deductions:
Business deductions
Personal deductions (mortgage interest, charitable giving, etc.)
Child tax credits
Any other credits you qualify for
Consider any withholding already happening
Your spouse's W2 withholding (if applicable)
Any withholding from other income sources
Divide your expected tax liability into quarterly payments
You need to pay enough to avoid penalties (usually 90% of current year's tax or 100% of last year's tax)
Payments don't have to be equal if your income varies throughout the year
As you can see, it's not just about your business profit - it's about your complete tax picture. Which is why it’s always hard to give a straight answer when I get asked “how much should I set aside or pay” - because I don’t know your whole situation!
What Happens If You Don't Pay Estimated Tax Payments For Small Business?
Let's be clear: the IRS takes these payments seriously. They can charge penalties if you:
Don't pay enough estimated tax
Don't make payments on time
Significantly underestimate your tax liability
The penalty isn't just a flat fee - it's calculated based on how much you underpaid and how long you waited to pay. The current IRS interest rate on underpayments can make those penalties add up quickly.
Making It Manageable
The good news? Once you understand the system, estimated taxes become much more manageable. '
Here are some practical tips:
Set up a separate savings account for taxes
PS if you use Bluevine (https://app.bluevine.com/signup/checking?pid_login=5001407&slug=0973ae639323431eb4f3151fd1cb7f45) you can create multiple different buckets to set aside money!
Track your income and expenses monthly to better estimate your profit
