These days, the 9-to-5 (“what a way to make a living,” in Dolly Parton’s famous words) is no longer the default setting for the American career.
In fact, in a recent survey, 59% of people said they would become entrepreneurs if they had the opportunity.
If quitting your 9-to-5 has been on your mind, I want to help you understand what your new relationship with the IRS would be if you become your own boss. So you can make your dream of entrepreneurship a reality without getting into a tax mess that could end up haunting you.
When you transition from being a W-2 employee to becoming self-employed, instead of your employer calculating and sending your taxes to the IRS, you become responsible for the timing, math, and documentation of every tax dollar owed.
These are the biggest shifts you’ll experience:
1. The Self-Employment (SE) tax shift
In a traditional job, you pay 7.65% for Social Security and Medicare, and your employer matches it. When you are self-employed, you are both the employer and the employee, meaning you pay the full 15.3%.
The silver lining, though, is that you can typically deduct 50% of your self-employment tax on your Form 1040, which lowers your overall taxable income.
2. Taxed on profit, not revenue
You only pay income and self-employment tax on your net profit (your revenue minus your deductible expenses). So if you earn $100,000 but spend $20,000 on valid business expenses, you’re only taxed on the remaining $80,000.
3. Quarterly estimated tax payments
Since there is no payroll department to withhold taxes from your paycheck, the IRS requires you to make quarterly estimated tax payments. These are typically due in April, June, September, and January.
If you’re self-employed, you pay two layers of federal tax: self-employment tax and federal income tax (state income tax in most cases). How much you pay depends on your net profit, deductions, filing status, and total household income.
Those we talk to who are going off on their own usually just want to know a simple self-employment tax rate. But there are actually a few layers to the cake to consider.
How much you pay depends on:
The self-employment tax piece is the one that feels most different coming from a W-2 world. It’s made up of a 12.4% Social Security tax and a 2.9% Medicare tax
That gives you the 15.3% figure. Which sits on top of your regular income tax calculation.
You start with net profit (rather than gross income), multiply it by 92.35%, and then apply the Social Security and Medicare rates.
Here’s the process we walk our clients through:
Step 1: Find your net profit
Start with your gross business income, then subtract your deductible business expenses. The equation is:
Revenue - Business Expenses = Net Profit
Step 2: Apply the 92.35% adjustment
Multiply that net profit by 92.35% to reflect the fact that an employer normally deducts its share of payroll taxes.
Net Profit × 0.9235 = Net Earnings Subject to SE Tax
Step 3: Apply the tax rates
Then you apply 12.4% for Social Security, subject to the wage base, and 2.9% for Medicare, generally with no wage cap.
Just to show you an example:
That’s roughly $14,130 you owe in self-employment tax.
That does not mean your total federal tax is $14,130. It’s just the self-employment tax portion before you even get into your regular federal income tax.
You pay self-employment tax during the year through quarterly estimated tax payments, not in one lump sum when you file. If you wait until April to pay everything, you’ll likely owe underpayment penalties even if you can afford the full balance then.
As an employee, you were paying tax all year long. But you weren’t feeling it as a separate event because withholding happened automatically.
Once that stops, the IRS still expects a pay-as-you-go system. It’s just no longer automated for you.
So, you have to pay quarterly estimated taxes. The 2026 estimated tax deadlines are:
Which means you’ll need to develop a habit of setting aside cash for taxes every time money comes in.
A good general rule to follow is reserving 25% to 30% of each payment you receive from a client for taxes. But the right number depends on your profit margins, state taxes, and household income.
This is a planning conversation, not a guessing game. So, if you’re seriously thinking about leaving your 9-to-5, it’s something we should sit down and figure out together.
When you’re self-employed, you can deduct ordinary and necessary business expenses. On top of that, certain deductions like health insurance, retirement contributions, and half of self-employment tax can reduce your taxable income even further.
This is the part of the conversation our clients tend to enjoy more.
A few of the major deduction categories available to you once you’re self-employed include:
There are also significant above-the-line deductions that can reduce adjusted gross income:
Of course, a doesn’t mean you’re getting reimbursed for the full expense. It just means you aren't paying taxes on that dollar.
So don’t spend money just to get a tax break. Focus on expenses that actually grow your business, and then make sure you document them properly so the IRS doesn't ask questions.
(And if you’re unsure whether a purchase really justifies a deduction, we can help you run the numbers.)
When you are self-employed, the burden of proof for every deduction falls on you. To satisfy the IRS and maximize your tax savings, you need to track expenses as they happen rather than guessing at tax time.
You need to maintain three main categories of records:
1. Core Financial Records
2. Specialized Deduction Tracking
Employment and Tax Returns
Ultimately, the W-2 system hides most of the tax process from you. Self-employment puts that process in your hands. You gain flexibility and deductions, but you also take on the responsibility for withholding, recordkeeping, tax deposits, and planning.
As a W-2 employee, you’re largely a passenger in the tax system.
As a self-employed taxpayer, you’re running the tax side yourself.
But that heavier responsibility comes with more planning room too.

We want to help make your entrepreneurial vision a reality without the stress of tax obligations weighing on you.
So, let’s sit down and make a plan. We’ll talk about when your W-2 income will stop, what your new business will realistically earn, and what we should do now so your first year of self-employment doesn’t end with a nasty April surprise.

“Can I skip quarterly payments if I still have a part-time W-2 job?”
You might be able to skip separate quarterly payments if you increase the withholding at your W-2 job to cover the tax liability of your self-employment income. If your employer withholds enough to meet the safe harbor requirements (90% of your current year’s tax or 100% of last year’s tax), you can avoid underpayment penalties.
“What is the Qualified Business Income (QBI) deduction?”
The QBI deduction (Section 199A) allows many self-employed individuals to deduct up to 20% of their qualified business income from their federal income tax. It reduces your taxable income but doesn’t reduce your self-employment tax. Your eligibility depends on your total taxable income and the type of business you operate.
“How does self-employment tax work if I hire a contractor?”
When you pay an independent contractor $2,000 or more in a calendar year, you’re required to file Form 1099-NEC. To prepare for this, you should have every contractor fill out a Form W-9 before you pay them. While you don't withhold taxes from their pay, the amount you pay them is a deductible business expense that reduces your own taxable profit.
“Is my health insurance premium fully deductible?”
Yes, if you are self-employed and have a net profit, you can typically claim the self-employed health insurance deduction. Unlike standard medical deductions, you do not need to itemize to claim it. However, you can’t claim this deduction for any month you were eligible to participate in a health plan subsidized by your employer or your spouse’s employer.
“What happens if I miss a quarterly tax deadline?”
If you miss a deadline, you should pay as much as possible as soon as possible. The IRS calculates underpayment penalties based on how much you owed and how late the payment was. Making a partial payment mid-quarter is always better than waiting until the next official deadline to catch up.
“Do I need a separate bank account for my business?”
While not legally required, maintaining a separate business bank account is something I highly recommend. It creates a clean audit trail, prevents the commingling of personal and business funds, and makes it significantly easier to track deductible expenses and prove income if the IRS requests documentation.
