Self-employed and owe the IRS: sort your records, then your options
Educational information only, not tax, legal, or financial advice. We are not a CPA, enrolled agent, attorney, or the IRS. Talk to your own tax professional about your situation.
Short answer: When you work for yourself, no employer withholds tax for you, so income tax and self-employment tax have to go in through quarterly estimated payments, and missed estimates are a common way a balance builds (IRS: self-employed individuals tax center). Before you pick a payment option, separate business money from personal money and work out your real net profit for each open year, because every IRS payment option and form starts from those numbers. If you're a sole proprietor or independent contractor, you apply for a payment plan as an individual (IRS: payment plans). If you have employees and payroll taxes went unpaid, treat that as a separate and more urgent problem.
This page is for freelancers, gig workers, sole proprietors and small-business owners who owe the IRS or have a notice. It explains what's different about self-employed tax debt and how to get your records into a shape that a tax professional, or the IRS, can follow. Organized records don't decide any IRS result; they make the next conversation shorter and more accurate.
Why self-employed tax debt builds up
The IRS describes federal tax as pay-as-you-go: most of it should be paid during the year as you earn, through withholding or quarterly estimated payments (IRS: underpayment of estimated tax penalty). Wage earners have withholding. Self-employed people usually don't, so three things stack up:
- Self-employment tax. This is Social Security and Medicare tax for people who work for themselves. The rate is 15.3%: 12.4% for Social Security and 2.9% for Medicare. You generally owe it and file Schedule SE if your net earnings from self-employment were $400 or more (IRS: self-employment tax). It's on top of income tax.
- Estimated tax. Individuals, including sole proprietors, partners and S corporation shareholders, generally have to make estimated payments if they expect to owe $1,000 or more when the return is filed (IRS: estimated taxes). The IRS lists the usual due dates as April 15, June 15, September 15 and January 15 of the following year.
- Penalty and interest. If you don't pay enough during the year, you may owe the underpayment of estimated tax penalty, and late estimated payments can trigger it even if you're due a refund when you file. The IRS also charges interest on penalties.
The IRS says most taxpayers avoid the estimated tax penalty if they owe less than $1,000 after withholding and credits, or if they paid at least 90% of the current year's tax or 100% of the prior year's tax, whichever is smaller. If adjusted gross income was more than $150,000 ($75,000 if married filing separately), 110% replaces 100% (IRS: estimated tax penalty).
First, name which kind of tax debt you have
"Business tax debt" can mean very different things. Read each notice and match it to a row before you do anything else.
| What the notice is about | Whose debt it is | What the IRS says about it |
|---|---|---|
| Income tax and self-employment tax on your Form 1040 (Schedule C and Schedule SE) | Yours personally. A sole proprietorship has no existence apart from you, and its liabilities are your personal liabilities (IRS Publication 583). | Sole proprietors and independent contractors apply for a payment plan as individuals (IRS: payment plans). |
| The estimated tax penalty | Yours personally | The IRS sends a notice if you owe it. It generally can't be waived for reasonable cause, but it may be removed or reduced after a casualty, disaster or other unusual circumstance, and reduced in some cases if you retired after 62 or became disabled, or if your income varied during the year (see below). |
| Payroll taxes you withheld from employees (Form 941) | The business, and possibly you personally | These are trust fund taxes. If they can't be collected from the business, the Trust Fund Recovery Penalty may be assessed against a responsible person (see below). |
| A tax owed by a business that files its own return | The business entity | Business taxpayers are told to call the number on their notice or visit a Taxpayer Assistance Center, and the business collection form is Form 433-B (IRS: payment plans). |
If you have an LLC, check how it files. The IRS says an LLC may be classified for federal income tax purposes as a partnership, a corporation, or an entity disregarded as separate from its owner (IRS Publication 583). How yours files decides which row fits. If you're not sure, that's the first question for a tax professional.
Step 1: separate business money from personal money
The IRS's own small-business guide says one of the first things to do when you start a business is open a business checking account and keep it separate from your personal checking account, and that the business checkbook is your basic source for recording business expenses (IRS Publication 583). If you didn't do that, you can still separate the past after the fact. Use the worksheet below and sort every deposit and payment for each open year into one of three labels:
- Business: client payments, sales, payment-processor deposits, and costs you paid only to run the business.
- Personal: household bills, transfers between your own accounts, gifts, and repayments from family or friends.
- Mixed: anything used for both, such as a car, phone or internet. The IRS's example is a florist who drove a van 20,000 miles, 16,000 of them for deliveries, and could claim only 80% of the van's operating cost as a business expense (IRS Publication 583). Write down how you split each mixed item, and why.
For each business expense, the IRS says your documents should show the payee, the amount, proof of payment, the date, and what was bought (IRS: what kind of records should I keep). Bank and card statements prove payment; an invoice or receipt shows what it was for. The IRS also suggests organizing supporting documents by year and by type of income or expense, which is exactly the folder layout this worksheet uses.
Payment apps and Form 1099-K
If clients pay you by card, the card processor sends a Form 1099-K no matter how many payments you got or how much they were for. Payment apps and online marketplaces must send one when your payments for goods or services total over $20,000 in more than 200 transactions, though they may send one for less (IRS: understanding your Form 1099-K). Either way, the IRS says you must report all income on your return, whether or not you get a 1099-K. Money from friends and family as a gift or repayment of a personal expense isn't taxable income and shouldn't be on a 1099-K; the IRS suggests marking those payments as non-business in the app when you can.
Step 2: work out net profit for each open year
Self-employment tax and income tax both start from net profit: business income minus business expenses (IRS: self-employed tax center). Once a year's deposits and payments are labeled, total the "business" income and the "business" expenses (plus the business share of mixed items). That's the number a preparer needs to check a filed Schedule C or prepare a missing one.
- If you've lost track of which 1099s were filed under your name, a wage and income transcript lists the income forms the IRS has; see the IRS records that help you rebuild a year.
- If a year was never filed, start with what to do about unfiled tax returns before you discuss payment options. The IRS's online long-term payment plan requires that all required returns be filed (IRS: payment plans).
- For the rest of the paperwork a year needs (notices, payment proof, a cover sheet), use the tax debt documents checklist.
Step 3: stop the balance from growing
An old balance is hard to pay down while a new one forms behind it. For the current year, use the worksheet in Form 1040-ES to see whether you need to make estimated payments and how much (IRS: estimated taxes). The IRS's payment plan page says not paying taxes when they're due may lead to a Notice of Federal Tax Lien or a levy, and interest and some penalties keep adding up until the balance is paid in full (IRS: payment plans). For what those two words mean, see IRS tax lien vs levy.
Our suggestion, not an IRS rule: once you know your estimated payment from Form 1040-ES, move a share of every client payment into a separate savings account the day it arrives, so the quarterly payment is already set aside when it's due.
Step 4: what the IRS asks for if you need a payment plan
As a sole proprietor or independent contractor you apply as an individual. The IRS says individuals may apply online for a long-term payment plan if they owe $50,000 or less in combined tax, penalties and interest and have filed all required returns, and for a short-term plan (180 days or less) if they owe less than $100,000 (IRS: payment plans). If you can't make the minimum payment the online tool asks for, the IRS gives directions for a collection information statement: Form 433-H or 433-F, or Form 433-B for businesses.
Form 433-F has parts written for self-employed people (IRS Form 433-F, Rev. 7-2024):
- Net self-employment income is what you earn after paying ordinary and necessary monthly business expenses. It should relate to your Schedule C net profit or your current-year profit and loss statement, and the form asks you to attach a copy. If net income is a loss, you enter 0.
- Business information (Section E) is for anyone with self-employment income, including income from online sales. It asks about accounts receivable and whether you accept card payments.
- Accounts and assets include business accounts and business assets such as tools, equipment, inventory, and intangible assets like domain names.
- Estimated tax payments count as a monthly expense: the quarterly amount from Form 1040-ES divided by 3.
The worksheet's year totals feed straight into those lines. For the household side of the budget and how the IRS's expense standards work, see how to build a tax-debt budget the IRS can follow. To compare a payment plan with an offer in compromise, see IRS payment plan or offer in compromise. If you truly can't pay anything right now, see currently not collectible status.
If the estimated tax penalty is part of the balance
According to the IRS, the estimated tax penalty generally can't be waived for reasonable cause alone. It may be removed or reduced if the underpayment came from a casualty, local disaster or other unusual circumstance where the penalty wouldn't be fair; or reduced if you or your spouse retired after reaching 62 or became disabled in the past 2 years and had reasonable cause. If your income came in unevenly, the IRS points to Form 2210 Schedule AI, the annualized income installment method (IRS: estimated tax penalty). Seasonal and project-based work often fits that last description, so ask your preparer whether Schedule AI was used. For other penalty types, see IRS penalty relief.
If you have employees: unpaid payroll taxes
Income tax and Social Security and Medicare tax withheld from employees' pay are called trust fund taxes, because the business holds the employees' money in trust until it makes the federal tax deposit (IRS: Trust Fund Recovery Penalty). The IRS's description of what can happen when they go unpaid:
- The Trust Fund Recovery Penalty may apply if the unpaid trust fund taxes can't be immediately collected from the business, and the business doesn't have to have stopped operating.
- It may be assessed against any person who was responsible for collecting or paying the taxes and willfully failed to. The IRS says using available funds to pay other creditors when the business can't pay its employment taxes is an indication of willfulness.
- The penalty equals the unpaid income tax withheld plus the employees' share of withheld FICA taxes.
- If the IRS determines you're a responsible person, it sends a letter proposing the penalty, and you have 60 days from the letter's date to appeal (75 days if it's addressed to you outside the United States). Once the penalty is asserted, the IRS can take collection action against your personal assets.
Federal tax deposits must be made electronically (IRS: depositing and reporting employment taxes), and the IRS says to keep all employment tax records for at least four years (IRS: recordkeeping). If you have a letter proposing this penalty, note the 60-day date first and talk to a qualified tax professional before it passes.
Record-separation worksheet
Download the blank record-separation worksheet (CSV). Open it in any spreadsheet app and keep the filled copy offline. Use one tab or copy per tax year. Each row is one deposit or payment: date, amount, who paid or was paid, your label (business, personal or mixed), the business share for mixed items, the document that proves it, and a note. The year-summary rows at the bottom total business income, business expenses, net profit, estimated payments already made, and any notice for that year.
Example (made up)
This is a hypothetical freelancer to show how the pieces fit. It isn't a real case and isn't advice. A graphic designer ran every client payment through a personal checking account and made no estimated payments for 2025. Sorting the year's statements, they find $61,000 in deposits: $54,400 from clients, a $6,000 transfer from their own savings and a $600 repayment from a friend, so business income is $54,400. They label $7,900 of software, equipment and a co-working membership as business, and their phone as mixed at a share they write down and explain. A payment-app 1099-K arrives showing less than the client total, so they keep the full $54,400 on the sheet, since all income gets reported either way. The year summary gives their preparer one net-profit figure with a document behind every line.
Mistakes the IRS's own rules warn against
- Treating "no 1099" as "no income." The IRS says you must report all income whether or not you get a Form 1099-K (IRS: Form 1099-K).
- Paying other bills ahead of payroll taxes. The IRS names this as an indication of willfulness for the Trust Fund Recovery Penalty (IRS: TFRP).
- Skipping this year's estimates to pay last year's bill. That starts a new balance with its own penalty and interest (IRS: estimated tax penalty).
- Listing a business loss as negative income on Form 433-F. The form says to enter 0 if net self-employment income is a loss (Form 433-F).
- Guessing mixed expenses under pressure. Decide and write down the split for each mixed item once, the way the IRS's mileage example does, and use the same method every year.
Questions to bring to a tax professional
- Which of my notices are personal (Form 1040) and which, if any, belong to a business entity or payroll account?
- How does my LLC or business file, and does that change who owes what?
- Were my filed Schedule C figures right, given the worksheet totals?
- Would Form 2210 Schedule AI lower an estimated tax penalty for a year when my income was uneven?
- What should my estimated payments be this year so a new balance doesn't form?
- If I have employees, is any payroll tax period unpaid, and is there a deadline on a letter about it?
