Divorce and Taxes: How to Protect Yourself from Your Ex-Spouse’s Financial Mistakes
October 16, 2025W-2 vs 1099: The Complete Guide to Understanding Your Tax Forms and Employment Status
October 16, 2025If you’re self-employed, a freelancer, a gig worker, or earn income outside of a traditional W-2 job, you’ve likely heard about quarterly tax payments. Yet for many taxpayers, estimated taxes remain one of the most confusing and overlooked aspects of tax compliance—often leading to surprise tax bills and costly penalties.
Understanding quarterly taxes isn’t just about staying compliant; it’s about taking control of your finances, avoiding unnecessary penalties, and ensuring you’re never caught off guard when tax season arrives.
What Are Quarterly Tax Payments?
Quarterly tax payments, officially called “estimated tax payments,” are payments you make to the IRS (and often your state) four times per year to cover income taxes and self-employment taxes on income that isn’t subject to withholding.
Why They Exist
The U.S. tax system operates on a “pay-as-you-go” basis. When you work for an employer, taxes are automatically withheld from each paycheck and sent to the IRS throughout the year. However, when you’re self-employed or have other non-wage income, there’s no automatic withholding—so the responsibility falls on you to make estimated payments.
The IRS expects to receive tax payments throughout the year, not just on April 15th. Quarterly payments ensure a steady flow of revenue to the government and prevent taxpayers from facing overwhelming tax bills once a year.
Who Needs to Make Quarterly Tax Payments?
You generally need to make estimated tax payments if you expect to owe at least $1,000 in taxes when you file your return, and your withholding and refundable credits will be less than the smaller of:
- 90% of the tax shown on your current year’s tax return, or
- 100% of the tax shown on your prior year’s tax return (110% if your adjusted gross income was more than $150,000)
Common Situations Requiring Quarterly Payments
Self-Employed Individuals
- Freelancers and independent contractors
- Consultants
- Sole proprietors
- Single-member LLC owners
- Gig economy workers (Uber, Lyft, DoorDash, etc.)
Business Owners
- Partnership owners receiving K-1 income
- S-corporation shareholders with pass-through income
- Anyone running a side business
Investors and Passive Income Earners
- Landlords with rental income
- Stock traders and investors with capital gains
- Dividend and interest income earners
- Cryptocurrency traders with significant gains
Other Income Sources
- Retirement distributions (IRA, 401k withdrawals)
- Unemployment compensation
- Prizes and awards
- Alimony recipients (for divorces finalized before 2019)
Who Doesn’t Need to Pay Quarterly?
You may not need to make quarterly payments if:
- You’re a W-2 employee with adequate withholding
- You owed less than $1,000 in taxes last year
- Your withholding covers at least 90% of your current year tax liability
- You had no tax liability for the prior year (and were a U.S. citizen or resident for the full year)
The 2025 Quarterly Tax Payment Deadlines
Mark these dates on your calendar—missing them can result in penalties:
Q1 (January 1 – March 31): April 15, 2025 Q2 (April 1 – May 31): June 16, 2025 Q3 (June 1 – August 31): September 15, 2025 Q4 (September 1 – December 31): January 15, 2026
Notice that the quarters aren’t exactly three months each, and the payment periods don’t align with calendar quarters. These dates are set by the IRS and have remained consistent for years.
💡 Important Note: If the due date falls on a weekend or federal holiday, the deadline moves to the next business day.
What Happens If You Miss a Deadline?
Missing a quarterly payment deadline doesn’t mean you can skip it entirely. You should still make the payment as soon as possible to minimize penalties and interest. The IRS assesses an underpayment penalty for each period you’re late or underpaid, calculated from the due date until the payment is made (or until your tax return filing date, whichever is earlier).
How Much Should You Pay Each Quarter?
Determining your quarterly payment amount is crucial—pay too little and you’ll face penalties; pay too much and you’re giving the IRS an interest-free loan.
Calculation Methods
Method 1: Prior Year Safe Harbor (Easiest) Pay 100% of last year’s total tax liability (110% if your AGI was over $150,000), divided by four. This guarantees you won’t face underpayment penalties, regardless of how much you make this year.
Example: If your 2024 tax liability was $20,000, pay $5,000 per quarter in 2025.
Advantage: Simple and provides penalty protection Disadvantage: May not reflect current year income changes
Method 2: Current Year Estimate (Most Accurate) Estimate your current year’s total tax liability and pay 90% of it in quarterly installments.
Steps:
- Estimate your annual gross income
- Subtract deductions (standard or itemized)
- Calculate income tax on taxable income
- Add self-employment tax (15.3% on net self-employment income)
- Subtract any credits
- Divide by four for quarterly amount
Advantage: More accurate to current year situation Disadvantage: Requires forecasting and may need adjustments
Method 3: Annualized Income Method (Most Complex) If your income varies significantly throughout the year, you can use the annualized income installment method, which bases each payment on your actual income earned during that quarter.
Advantage: Accounts for seasonal businesses or irregular income Disadvantage: Requires detailed record-keeping and Form 2210
Understanding Self-Employment Tax
If you’re self-employed, don’t forget about self-employment tax—the self-employed person’s version of Social Security and Medicare taxes. This is 15.3% (12.4% for Social Security + 2.9% for Medicare) on your net self-employment income up to $168,600 for 2024 (indexed annually), and 2.9% Medicare tax on all income above that threshold.
Unlike employees who split these taxes with their employer, self-employed individuals pay the full amount themselves. The good news? You can deduct half of your self-employment tax as an adjustment to income.

Common Quarterly Tax Payment Mistakes (And How to Avoid Them)
Mistake #1: Not Making Payments at All
The Problem: Many first-time self-employed individuals don’t realize they need to make quarterly payments until they receive a penalty notice or face a massive tax bill.
The Solution: If you’re newly self-employed or have significant non-wage income, set up quarterly payments immediately. It’s better to overpay slightly and get a refund than to underpay and face penalties.
Mistake #2: Underestimating Income
The Problem: Business is going better than expected, but you’re still basing payments on conservative estimates.
The Solution: Review and adjust your quarterly payments if your income increases significantly. The IRS allows you to pay more in later quarters to make up for earlier underpayments.
Mistake #3: Forgetting About Deductions
The Problem: Calculating payments based on gross income without accounting for legitimate business deductions.
The Solution: Track deductible expenses throughout the year—home office, mileage, supplies, software, professional development—and factor these into your income estimates.
Mistake #4: Missing Deadlines
The Problem: Losing track of payment dates, especially Q2 (June) and Q4 (January).
The Solution: Set calendar reminders two weeks before each deadline. Better yet, schedule payments through EFTPS in advance.
Mistake #5: Not Keeping Records
The Problem: Failing to maintain documentation of when and how much you paid.
The Solution: Save confirmation numbers, receipts, and bank statements for all quarterly payments. These are crucial if the IRS questions your payments.
Mistake #6: Ignoring State Taxes
The Problem: Making federal payments but forgetting state estimated taxes.
The Solution: Research your state’s requirements and set up both federal and state quarterly payments simultaneously.
Mistake #7: Thinking You Can Catch Up at Year-End
The Problem: Missing quarterly payments and planning to pay it all when filing your return.
The Solution: Penalties are assessed per quarter, so making a large payment in January doesn’t eliminate penalties for earlier quarters. Stay on schedule.
Penalties and Interest: What You Need to Know
The IRS charges an underpayment penalty when you don’t pay enough tax throughout the year via withholding or estimated payments. This penalty is actually interest charged on the underpayment from the due date of the payment until it’s paid.
How Penalties Are Calculated
The underpayment penalty is calculated using the federal short-term rate plus 3%, compounded daily. As of 2025, this rate typically ranges from 7-9% annually, though it changes quarterly.
The penalty is calculated separately for each quarterly period you underpaid, which means catching up in later quarters doesn’t eliminate earlier penalties—though it does reduce the total penalty amount.
Penalty Exceptions
You may avoid penalties if:
- Your total tax payments (withholding + estimated) equal at least 90% of current year tax
- Your total tax payments equal 100% of prior year tax (110% if high income)
- Your total tax due is less than $1,000
- You qualify for the annualized income method
- You had no tax liability in the prior year
- You experienced a casualty, disaster, or other unusual circumstance
First-Time Penalty Abatement
If you’ve never been penalized before (or haven’t been in the last three years), you may qualify for first-time penalty abatement. This one-time relief forgives penalties if you have:
- No penalties for the prior three tax years
- Filed all required returns (or extensions)
- Paid or arranged to pay any tax due
Strategies for Managing Quarterly Taxes
1. The Separate Savings Account Method
Open a dedicated savings account specifically for taxes. Every time you receive income, immediately transfer your estimated tax percentage (typically 25-30% for self-employed individuals) to this account. When quarterly payments are due, the money is already set aside.
Why It Works: Removes temptation to spend tax money and prevents cash flow problems when payments are due.
2. The Weekly Transfer Approach
Instead of thinking quarterly, think weekly. Divide your total estimated quarterly payment by 13 weeks and transfer that amount to your tax savings account each week.
Example: If you need to pay $3,000 per quarter, transfer approximately $230 per week.
Why It Works: Makes the financial burden feel smaller and more manageable, and you’ll always have your payment ready early.
3. The Profit First Method
Implement the Profit First system where you allocate percentages of every deposit to different accounts (operating expenses, profit, owner pay, and taxes) before spending anything.
Why It Works: Creates discipline and ensures taxes are treated as a priority, not an afterthought.
4. The Conservative Estimate Approach
When uncertain about your annual income, use the higher safe harbor method (100-110% of prior year tax). This ensures penalty protection even if your income increases unexpectedly.
Why It Works: Eliminates penalty risk and provides peace of mind. Any overpayment comes back as a refund.
5. The Monthly Review Ritual
Set a monthly appointment with yourself to review income, expenses, and tax payment adequacy. Adjust future quarterly payments based on actual performance.
Why It Works: Catches problems early and allows for course correction before penalties accumulate.
Special Situations and Considerations
Starting a Business Mid-Year
If you start your business in the middle of the year, you only need to make payments for the remaining quarters. However, calculate carefully to ensure you’re paying enough to avoid penalties.
Inconsistent Income
Freelancers and seasonal businesses with variable income should consider the annualized income method (Form 2210) or make larger payments in profitable quarters to compensate for slower periods.
Major Life Changes
Job loss, divorce, inheritance, home sale, or other significant financial events can dramatically impact your tax situation. Recalculate estimated taxes immediately when these occur.
Retirement Account Contributions
Remember that traditional IRA and SEP-IRA contributions reduce your taxable income, which can lower your quarterly payment requirements. Factor these in when calculating estimates.
Estimated Tax Payments vs. Increased Withholding
If you have a W-2 job plus self-employment income, you might adjust your W-4 to have more withheld from your paycheck rather than making separate quarterly payments. Withholding is considered paid evenly throughout the year (even if increased late in the year), which can help avoid underpayment penalties.
