Catching Up When You're a One-Person Business: Solo Stylists, Barbers and Trades
When the person cutting hair or fixing the furnace is also the bookkeeper, the books slide first, and the IRS rules for catching up favor the owner who files before anything else.
At a glance
- A solo catch-up plan is a short list of IRS steps in the order that costs least, followed by a set-aside habit sized to every ticket you ring up.
- Self-employed people owe self-employment tax of 15.3% once net earnings reach $400, on top of income tax, and nobody withholds it from a booth-rent stylist's or a solo plumber's pay.
- An unfiled return costs 5% of the unpaid tax each month, ten times the 0.5% monthly penalty for paying late, so filing every missing return is step one.
- Firms with no employees lean on the owner's own money to get through financial challenges more often than employer firms, at 64% compared with 54%, according to the Federal Reserve.
General information, not legal, tax or financial advice; talk to a licensed professional about your situation.
Part 1 | Nobody withholds tax from a chair, a van or a toolbox
A stylist renting a chair, a barber with a single station and an electrician working out of one van share a tax position that wage earners never see, because every dollar a client pays arrives whole and the tax on it is the owner's job to set aside. The IRS sets the self-employment tax rate at 15.3%, made up of 12.4% for Social Security and 2.9% for Medicare, and it applies once net earnings from self-employment reach $400 for the year. Income tax comes on top of that.
The IRS expects that money during the year rather than in April. Individuals, including sole proprietors, generally must make estimated payments if they expect to owe $1,000 or more when they file, and the payments are due April 15, June 15, September 15 and January 15 of the following year. A full book in December can hide the fact that the September payment never went out; the owner's inner voice usually says I'll catch it up when I do my taxes, and by then the underpayment penalty has been running for months.
| Income earned | Payment due |
|---|---|
| January 1 to March 31 | April 15 |
| April 1 to May 31 | June 15 |
| June 1 to August 31 | September 15 |
| September 1 to December 31 | January 15 of the next year |
Part 2 | File first, then arrange to pay
The order of the catch-up follows the IRS penalty rates. The failure-to-file penalty is 5% of the unpaid tax for each month or part of a month a return is late, up to 25%, while the failure-to-pay penalty is 0.5% a month, also capping at 25%; for a return more than 60 days late, the minimum failure-to-file penalty on returns due after December 31, 2025 is $525 or 100% of the tax owed, whichever is less.
The IRS tells taxpayers to file all returns that are due whether or not they can pay in full, and if a return never arrives it may file a substitute return that might not give credit for deductions. A barber who never filed can still build the return from bank deposits, card-processor reports and appointment records, and a wage and income transcript, requested through Get Transcript or Form 4506-T, shows the income information the IRS has on file.
Once the returns are in, the balance can go on a plan. Individuals who owe less than $100,000 can set up a short-term plan of up to 180 days with no setup fee, and those who owe $50,000 or less can set up a long-term plan online for $29 with direct debit or $69 with other payment methods, compared with $107 and $178 by phone, mail or in person. Interest and some penalties keep running on every plan, so paying the balance down faster still saves money.
A penalty can sometimes come off after the fact. The IRS first-time abatement waiver covers failure-to-file and failure-to-pay penalties for taxpayers who filed the same type of return on time for the prior three years with no penalties assessed, and it is worth asking about once the late returns are filed. For an owner with a dispute or a collection notice and a modest income, Low Income Taxpayer Clinics represent taxpayers before the IRS for free or a small fee, usually in disputes under $50,000, and they operate independently of the IRS.
Part 3 | A set-aside habit sized to every ticket
The way to keep from falling behind again is to move tax money out of reach on the day it comes in. A separate savings account labeled for taxes, a fixed percentage moved after every client or every job, and a quarterly payment from that account on the four dates in Exhibit 1 make a system that needs about ten minutes a week.
Checklist for the end of the week, after the last client or the last call
- Total the week's payments from the card reader, cash, payment apps and any invoices paid.
- Move your set-aside percentage into the tax account; your tax professional can help you choose the percentage.
- Photograph receipts for product, tools, parts, booth rent, mileage and supplies, and file them in one folder by month.
- Check that the bank deposits match what the appointment book or job list says you were paid.
- On the four due dates, pay the quarter's estimate from the tax account.
Keep the records long enough. The IRS generally asks taxpayers to keep records for three years, six years if income was left off a return, and indefinitely for any year with no return filed.
How you compare
- Owner's money: in the Federal Reserve's 2025 survey, 64% of nonemployer firms used the owner's personal funds to deal with financial challenges, compared with 54% of employer firms, so dipping into savings is common among solo owners and a signal that the set-aside habit is overdue.
- Your own baseline: count the missing returns and the quarterly estimates skipped in the last two years, then check the count again after the next due date.
Questions to ask this week
Which returns have I not filed? Start there, since the monthly penalty for an unfiled return is the largest.
What did the IRS receive about me? A wage and income transcript shows the income information others reported to the IRS.
What percentage will I move after every client? Pick a number with your tax professional and set it as a recurring transfer.
The first step this week is to request your IRS transcripts and write down every year that is missing a return.
