What Happens If You Pay Workers Under the Table? (Penalties, Risks & How to Fix It)

This article reflects federal rules and California rules as of June 2026 and covers tax year 2025 (filed in the 2026 season). Tax law changes — confirm current figures before you file.

Quick Answer

You break the law. Paying workers under the table for tax year 2025 means unpaid payroll taxes, back taxes with interest, civil fines, and possible criminal charges of up to $10,000–$100,000 and five years in prison. Both the employer and the worker face serious, lasting consequences.

The Real Cost of Off-the-Books Pay

Paying a worker “under the table” means handing over cash or checks without reporting the wages, without withholding taxes, and without filing the required payroll forms. The moment you skip that reporting, you stop being a late or sloppy taxpayer and become someone the IRS can treat as a tax cheat. The Internal Revenue Code calls willful failure to collect and pay over employment taxes a felony, and the IRS Criminal Investigation division refers these cases to the Department of Justice for prosecution.

The stakes are not small or far away. According to IRS data on employment tax evasion, convicted defendants in these cases face incarceration rates of roughly 70% to 77%, with average prison sentences of 14 months to 2 years. This is not a parking ticket. It is the kind of mistake that follows a business owner home, drains personal savings, and can end a company.

What “Paying Under the Table” Actually Means

Paying under the table is any arrangement where you pay someone for work but hide it from the government. The payment is real, but on paper it never happened. No wages get reported, no taxes get withheld, and no payroll forms get filed.

This is different from a few related things people confuse it with. It is not the same as hiring a true independent contractor and paying them with a Form 1099. It is also not the same as simply paying late. Under-the-table pay is the deliberate choice to keep work invisible, and that choice is what turns it into fraud.

Off-the-Books Cash vs. Misclassification

There are two main ways employers go wrong, and they carry different risks. The first is pure off-the-books pay, where cash changes hands and nothing is reported at all. The second is misclassification, where you pay a real employee as a “1099 contractor” to dodge payroll taxes.

Misclassification is more common and often starts by accident. The IRS explains worker classification using control: if you control what work is done and how it is done, the worker is usually an employee, not a contractor. Calling someone a contractor does not make them one. The consequence of getting this wrong is that the IRS can reclassify every payment as wages and bill you for the taxes you never withheld.

Why Employers Do It

Most employers pay under the table to save money in the short term. They skip the employer’s 6.2% Social Security tax and 1.45% Medicare tax, plus federal and state unemployment taxes, workers’ compensation premiums, and the paperwork burden. For tax year 2026, the Social Security tax rate is 6.2% each for employer and employee.

The trouble is that the “savings” are a loan against a future audit. When the bill comes due, it arrives with interest, penalties, and the employer’s share that you avoided — often several times the amount you thought you saved. The common misconception is that small cash payments are too tiny to notice; in reality, a single disgruntled worker filing for unemployment can trigger the whole unraveling.

Which Situation Applies to You?

The consequences depend heavily on your role and your facts. Use this to find the part of the article that fits you.

You are an employer paying cash with no reporting. Your biggest risks are unpaid employment taxes, the Trust Fund Recovery Penalty, and criminal exposure. Read the federal penalty and criminal sections closely.
You are an employer who labeled employees as 1099 contractors. Your path may include Section 530 relief or the Voluntary Classification Settlement Program. Read the misclassification and fix-it sections.
You are a worker paid in cash. You still owe income tax and you risk losing Social Security credits, workers’ comp, and unemployment. Read the worker-consequences and Form 8919 sections.
You operate in California. Add state income tax withholding, state payroll taxes, and steep state misclassification penalties on top of everything federal. Read the California section.

Federal Penalties for Employers

When the IRS catches under-the-table pay, it rebuilds the payroll that should have existed and bills you for all of it. The penalties stack, and they do not stack gently.

Back Taxes and the Employer’s Share

First, you owe the taxes that were never withheld or paid. The IRS reclassifies the cash as wages and assesses income tax withholding, the employee’s share of Social Security and Medicare, and your matching employer share. Per the IRS worker classification guidance, the employer becomes liable for employment taxes on those wages.

The consequence is that you pay both halves of FICA — your 7.65% and often the worker’s 7.65% you failed to collect — plus federal unemployment tax. A common misconception is that the worker owes their own share; once you fail to withhold, the IRS comes to you first. Your next step is to total the cash paid per worker per year so you can estimate the real exposure before the IRS does it for you.

Failure-to-File and Failure-to-Pay Penalties

On top of the tax, the IRS adds penalties for the returns you never filed. The failure-to-file penalty and the late-filing penalty on Form 941 run at 5% of the unpaid tax per month, up to a 25% maximum, and the failure-to-pay penalty adds 0.5% per month, also up to 25%.

Interest then runs on top of both, compounding daily from the original due dates. The consequence is that a three-year-old unpaid payroll bill can nearly double once penalties and interest finish stacking. The practical step here is to file the missing returns as soon as possible, because the monthly penalty stops growing the moment you file.

Information-Return Penalties (W-2s)

Every employee should get a Form W-2, and every missing or wrong W-2 carries its own fine. For tax year 2025, the IRS information-return penalties are $60 per form if corrected within 30 days, $130 if corrected by August 1, and $340 per form if filed late or never corrected.

If the IRS decides you ignored the rule on purpose, the intentional-disregard penalty for tax year 2025 starts at $680 per form with no maximum cap. The consequence scales fast: 20 unreported workers can mean thousands in W-2 penalties alone. Your step is to issue corrected W-2 forms before the IRS assesses the higher tiers.

The Misclassification Math

If the failure was unintentional, the misclassification penalties are lighter but still real: a $50 fine per unfiled W-2, 1.5% of the wages paid, and 40% of the employee’s unpaid FICA, plus 100% of the employer’s matching FICA. If the IRS suspects fraud, the numbers jump to 20% of all wages paid plus 100% of both shares of FICA, and criminal fines up to $1,000 per worker.

The Trust Fund Recovery Penalty (Personal Liability)

The scariest federal tool is the Trust Fund Recovery Penalty, or TFRP, because it pierces the business and reaches your personal wallet. The taxes you withhold from a paycheck are called “trust fund” taxes — you hold them in trust for the government. When you fail to pay them over, the Trust Fund Recovery Penalty lets the IRS collect 100% of that amount from the responsible individual.

The penalty equals the full unpaid trust fund portion — the withheld income tax plus the employee’s share of Social Security and Medicare. As tax practitioners explain the TFRP, if your company failed to deposit $50,000 in withheld payroll taxes, you personally could owe $50,000 — even though you never kept a dime of it. An LLC or corporation does not protect you here.

The IRS can assess the TFRP against any “responsible person” who willfully failed to pay, including owners, officers, and even bookkeepers with check-signing authority. The consequence is personal liens, levies, and wage garnishment that survive even if the business closes. If you receive Letter 1153 proposing the TFRP, your step is to respond within 60 days and get a tax attorney involved fast.

Criminal Consequences

Under-the-table pay can move from a civil bill to a criminal charge when the conduct is willful. Willful means you knew the right thing to do and chose not to do it. At that point the IRS Criminal Investigation Division can build a case and hand it to the Department of Justice.

Employment tax evasion is a felony. A conviction can bring fines up to $10,000 or even $100,000 in serious cases, restitution of all unpaid tax, and imprisonment of up to five years. The consequence that surprises people most is the high incarceration rate — roughly 70% to 77% of convicted defendants serve time, averaging 14 months to 2 years.

The common misconception is that prosecutors only chase large corporations. In reality, small-business owners are frequent targets precisely because the facts are simple to prove. If you are already under investigation, your only safe step is to stop talking to agents and hire a criminal tax attorney immediately.

Consequences for the Worker

The worker is not off the hook. Cash is still taxable income, and the worker must report and pay tax on it even when no W-2 arrives. Skipping that filing is itself tax fraud, with the worker owing back taxes, interest, and penalties.

Beyond taxes, off-the-books work quietly erases safety nets. Because no payroll taxes were paid, the worker can lose access to workers’ compensation if hurt on the job, unemployment insurance if laid off, and future Social Security and Medicare benefits because the earnings never hit their record. The consequence shows up years later as a smaller retirement check.

Form 8919 — The Worker’s Way Out

A worker who was treated as a contractor but should have been an employee has a tool. The Form 8919 lets the worker report and pay only their own half of Social Security and Medicare — not the employer’s half — and still get the earnings credited to their Social Security record.

To qualify, the worker usually files Form SS-8 first to ask the IRS for an official status determination. The consequence of using Form 8919 instead of self-employment tax is real savings, because the worker avoids paying the employer’s share that the employer wrongly pushed onto them. The step is to file Form 8919 with the annual Form 1040 and attach the SS-8 result.

Worked Example: The True Cost

Numbers make this concrete. Meet Dave, who runs a small landscaping crew and paid one worker $40,000 in cash during 2025 with nothing reported.

Here is the federal math when the IRS reclassifies the cash as wages:

Employee FICA (7.65% of $40,000): $3,060, which the IRS bills to Dave because he failed to withhold it.
Employer FICA (7.65% of $40,000): $3,060, Dave’s own required share.
Federal income tax withholding the IRS estimates was owed: roughly $4,000 (varies by the worker’s status).
Failure-to-file and failure-to-pay penalties: up to 25% each on the unpaid amounts.
W-2 penalty for the missing form (intentional, tax year 2025): $680.

Before interest, Dave’s roughly $3,060 in “savings” has ballooned past $10,000, and that excludes the possible 100% Trust Fund Recovery Penalty and California’s state penalties. If the IRS finds willfulness, criminal exposure enters the picture too.

Three Common Scenarios

These are the patterns the IRS sees most often.

Scenario 1 — The all-cash small business

The Move	What It Costs You
Owner pays a cook $35,000 cash, files nothing	Back FICA on both shares, income tax withholding, 25% failure-to-file penalty, W-2 fines, and personal TFRP liability of the full trust fund amount

Scenario 2 — The “1099 contractor” who is really an employee

The Move	What It Costs You
Salon labels stylists as contractors to skip payroll tax	IRS reclassifies wages, bills 1.5% of wages plus 40% of employee FICA and 100% of employer FICA; California adds its own misclassification fines

Scenario 3 — The worker who never filed

The Move	What It Costs You
Worker takes cash and reports no income	Back income tax, interest, fraud penalty, plus lost Social Security credits and no workers’ comp if injured

Three Real-World Mini-Scenarios

Maria runs a cleaning company and paid four staff in cash to “keep it simple.” One employee fell off a ladder, filed for workers’ compensation, and the claim exposed the whole off-books payroll. Maria now owes years of back payroll tax, penalties, and a workers’ comp investigation.

James classified his delivery drivers as 1099 contractors. A driver filed Form SS-8, the IRS ruled them employees, and James faced reclassification of every payment plus 1.5% wage and 40% FICA penalties — until his accountant moved him into a settlement program.

Aisha was paid cash as a “contractor” but worked set hours under tight supervision. She filed Form 8919, paid only her own FICA share, and protected her Social Security record while shifting the misclassification spotlight onto her employer.

How to Fix It: Coming Into Compliance

If you have been paying under the table, the safest move is to fix it before the IRS finds you. Voluntary correction almost always costs far less than getting caught.

The Voluntary Classification Settlement Program (VCSP)

The Voluntary Classification Settlement Program lets eligible employers reclassify workers as employees going forward while paying only a small fraction of the employment taxes that would otherwise be due for one past year. You apply with Form 8952, filed at least 120 days before the date you want the reclassification to start.

The benefit is large: you avoid the full back-tax assessment, interest, and most penalties, and you sign a closing agreement with the IRS. The consequence of skipping this and waiting for an audit is paying the entire stacked penalty regime instead. The step is to confirm eligibility, file Form 8952, and begin treating the workers as employees on the agreed date.

Filing Back Returns and Section 530 Relief

If the VCSP does not fit, you can still file the missing Forms 941 and W-2 and pay what you owe. Filing voluntarily stops the failure-to-file penalty from growing and signals good faith, which can reduce fraud exposure. Some employers also qualify for Section 530 relief, a safe harbor that forgives back employment taxes if you had a reasonable basis for treating workers as contractors and filed consistent 1099s.

California: State Penalties on Top of Federal

California stacks its own consequences on top of everything federal, and the state is aggressive. Beyond federal payroll taxes, employers must withhold and remit through the California Employment Development Department, which handles state income tax withholding, State Disability Insurance, and unemployment tax.

California also uses the strict “ABC test” from its labor law to decide who is an employee, and it is much harder to call a worker a contractor in California than under federal rules. Under California Labor Code 226.8, willful misclassification carries civil penalties of $5,000 to $15,000 per violation, rising to $10,000 to $25,000 per violation for a pattern of misclassification. The consequence is that a California employer can owe state penalties that dwarf the federal bill, plus unpaid wages, overtime, and missed-break penalties under state wage law.

Mistakes to Avoid

Calling an employee a “contractor” to dodge payroll tax. The IRS reclassifies the wages and bills you for both FICA shares plus penalties.
Paying only in cash with no records. Without records you cannot defend yourself, and the IRS can estimate wages against you.
Assuming an LLC protects you from the TFRP. The Trust Fund Recovery Penalty reaches you personally, regardless of entity.
Ignoring an IRS or EDD notice. Missing the 60-day window on Letter 1153 lets the TFRP become final.
Thinking small amounts are invisible. One unemployment or workers’ comp claim can expose your entire off-books payroll.
Trusting a handshake “the worker agreed to cash.” The worker’s consent is no defense; the legal duty to withhold is yours.
Waiting for an audit instead of self-correcting. Voluntary fixes through the VCSP cost a fraction of getting caught.
Filing 1099s inconsistently. Inconsistent filings disqualify you from Section 530 safe-harbor relief.

Do’s and Don’ts

Do classify workers by control, not by label — because the IRS looks at who controls the work, not what you call it.
Do withhold and deposit payroll taxes on time — because late deposits trigger the failure-to-deposit penalty and TFRP.
Do keep clean payroll records — because documentation is your only defense in an audit.
Do consider the VCSP if you misclassified workers — because it slashes back taxes and penalties.
Do separate federal and state obligations — because states like California do not follow federal rules.
Don’t pay wages in unreported cash — because it converts a civil problem into criminal fraud.
Don’t assume the worker carries the tax burden — because the IRS pursues the employer first.
Don’t ignore an SS-8 filing by a worker — because it signals the IRS is reviewing your classifications.
Don’t destroy records to hide payments — because that adds obstruction charges on top of tax fraud.
Don’t go it alone in a criminal matter — because only a tax attorney can protect privileged communications.

Pros and Cons of Coming Forward Voluntarily

Pro: Lower cost — voluntary programs forgive most back taxes and penalties.
Pro: Reduced criminal risk — coming clean undercuts the “willfulness” the government needs.
Pro: A clean closing agreement — the VCSP ends the matter with the IRS in writing.
Pro: Protected workers — your staff regain Social Security credits and benefit eligibility.
Pro: Peace of mind — you stop the daily compounding of interest and penalties.
Con: Upfront cost — you must pay back taxes and start real payroll, which raises labor costs.
Con: State exposure remains — federal programs do not settle California’s separate penalties.
Con: Higher ongoing payroll — adding payroll tax and workers’ comp raises your true labor expense.
Con: Eligibility limits — you cannot use the VCSP if you are already under audit for classification.
Con: Possible scrutiny — coming forward puts your prior years on the record.

What to Do Next

Total your exposure. List every worker, the cash paid, and the year, so you know the real numbers.
Stop the bleeding now. Begin proper withholding and payroll deposits on your next pay run.
File the missing forms. Submit the overdue Form 941 returns and issue corrected W-2 forms.
Choose a correction path. Apply to the VCSP with Form 8952 or pursue Section 530 relief if you qualify.
Handle your state separately. Contact the California EDD or your own state agency to clear state payroll obligations.
Call a professional. If criminal exposure, a TFRP letter, or a large balance is in play, hire a CPA or tax attorney before you respond to the IRS.

Frequently Asked Questions

Is it illegal to pay someone under the table? Yes. Paying wages without withholding and reporting them violates the Internal Revenue Code. It can bring back taxes, civil penalties, and — if willful — felony charges with up to five years in prison.

Will I go to jail for paying cash? It is possible. Willful employment tax evasion is a felony with incarceration rates of roughly 70% to 77% for convicted defendants. Honest, voluntary correction sharply lowers the criminal risk.

Can my LLC protect me from the penalties? No. The Trust Fund Recovery Penalty reaches responsible individuals personally for 100% of unpaid withheld taxes, regardless of whether you operate as an LLC or corporation.

Does the worker owe taxes too? Yes. Cash wages are taxable income the worker must report for tax year 2025. Failing to report it is also tax fraud, and the worker loses benefit credits.

What is the penalty for a missing W-2? Up to $340 per form for tax year 2025 if filed late or never corrected, and at least $680 per form if the IRS finds intentional disregard, with no maximum cap.

What is the Trust Fund Recovery Penalty? It is 100% of unpaid trust fund taxes. The IRS assesses it personally against owners, officers, or bookkeepers who willfully failed to pay over withheld income, Social Security, and Medicare taxes.

How can I fix misclassified workers? Use the VCSP. File Form 8952 at least 120 days before the reclassification date to reclassify workers going forward and pay only a fraction of back employment taxes.

What form does a misclassified worker file? Form 8919. It lets the worker pay only their own Social Security and Medicare share and credit the earnings to their record, usually after filing Form SS-8 for a status ruling.

Does California follow the federal rules? No. California uses its stricter “ABC test” and adds penalties of $5,000 to $25,000 per willful misclassification under Labor Code 226.8, on top of all federal consequences.

How far back can the IRS go? There is no time limit on unfiled returns. When no Form 941 or W-2 was filed, the assessment window never starts, so the IRS can reach back many years for unreported wages.

What happens if a worker gets hurt off the books? You face a workers’ comp claim and exposure. The injury can reveal your entire off-books payroll, triggering tax assessments, state penalties, and possible uninsured-employer liability.

Can I just file the back payroll forms myself? Yes, and you should. Filing overdue Form 941 returns and W-2s stops the failure-to-file penalty from growing and shows good faith, though a professional should review large or willful cases.
