Every full-service restaurant in the United States that pays Social Security and Medicare tax on tip income is sitting on a federal tax credit it can claim, dollar for dollar, against the income tax it owes. The credit is established under Internal Revenue Code §45B. It is claimed on IRS Form 8846. It is available to any restaurant where tipping is customary, regardless of whether the restaurant uses the tip credit toward minimum-wage compliance. And in any given year, somewhere between 30% and 60% of eligible restaurants — by the most generous estimates published in the trade press — fail to claim it.
The reason is not complicated. The credit lives in a corner of the tax code that most general-practice CPAs encounter once or twice a year. It requires payroll-system data that some preparers do not bother to extract. And it produces a deduction — a real, federal-income-tax-reducing deduction — that compounds quietly across the years it goes unclaimed. For an operator running a four-server, $1.4M-revenue trattoria, the annual savings is in the neighborhood of $9,000. Across five years of an unclaimed credit, that is more than enough to renovate the kitchen.
What follows is a complete explanation of how §45B works, who qualifies, what the calculation looks like, what your bookkeeper needs to give your tax preparer to claim it, and the three most common reasons it gets missed. By the end you should be able to determine, in about four minutes, whether your last three years of returns left this credit on the table.
What §45B actually does.
The mechanics are straightforward once you see the structure. When a server in your restaurant earns $200 in tips on a Friday night, that tip income is, for federal tax purposes, the server's wages. The server reports those tips to you (typically through your POS), and you, as the employer, are required to pay the employer's share of FICA tax — 6.2% Social Security plus 1.45% Medicare, for a combined 7.65% — on those tips. On a $200 tip, your employer FICA cost is $15.30. Across a busy week, across four servers, across fifty-two weeks of operation, the employer FICA on tips for a typical mid-volume restaurant runs $40,000 to $90,000 per year. It is a real cost, and it appears on your books as a payroll-tax expense.
Section 45B does something simple and unusual: it lets you take the employer FICA you paid on tips above the federal minimum wage and claim it as a tax credit — not a deduction, but a credit, applied dollar-for-dollar against the income tax you owe. The credit applies only to the portion of FICA paid on tips in excess of what the employee would have made earning the federal minimum wage of $5.15 per hour (the rate frozen into the credit calculation by statute, not the current federal minimum). Above that hourly threshold, every dollar of employer FICA you paid on tip income converts into a dollar of federal tax credit.
The result, in practical terms: the IRS effectively reimburses restaurants for the payroll tax the IRS itself collected on tip income, on the theory that tipping is a form of compensation the employer didn't actually pay and shouldn't be tax-burdened to facilitate. Whatever you think of the policy logic, the credit is there, it is current law, and the dollars are real.
Who is eligible.
The eligibility rules are narrower than they sound but broader than most operators realize. The credit applies to any restaurant that meets two conditions. First, the establishment must be one in which tipping is customary — defined by IRS regulation as a food or beverage business where customers ordinarily tip employees. Full-service restaurants, fine-dining establishments, casual-dining chains, bar-and-grills, and most bars qualify. Quick-service restaurants where tipping is not customary do not. Coffee shops are a gray area that depends on whether tip income is meaningful relative to wages.
Second, the employees whose tips drive the credit must be tipped employees as defined under federal labor law — meaning employees who customarily and regularly receive more than $30 per month in tips. Servers, bartenders, bussers in tip pools, and food runners who participate in tip distribution typically all qualify. Hosts, cooks, dishwashers, and managers do not, unless they participate in a valid tip pool that the IRS would recognize.
One eligibility rule that surprises most operators: the credit is available even if you do not take the FLSA tip credit toward minimum wage. A restaurant in California, where state law prohibits paying tipped employees below the standard minimum wage, can still claim the §45B FICA tip credit. The two credits — the FLSA tip credit (for minimum-wage purposes) and the §45B credit (for tax purposes) — are independent of each other. This is the single most common eligibility misconception we encounter. Operators in tip-credit-prohibited states often assume they don't qualify; they do.
The actual calculation.
The math is doable on a single page. For each tipped employee, for each pay period:
Step one: total the tip income reported by the employee. This is what your POS or your tip-allocation report shows.
Step two: calculate what that employee would have earned, in straight-time wages, working the same hours at the federal minimum wage of $5.15 per hour (yes, this is the historic figure frozen into the credit statute since 1996, not the current $7.25). For a server who worked 30 hours in a pay period, that is $5.15 × 30 = $154.50.
Step three: subtract the actual cash wages you paid the employee from that minimum-wage figure. If you paid the employee $7.50 per hour cash plus their tips, the employee earned $7.50 × 30 = $225 in cash wages. Since cash wages ($225) exceed the §5.15 baseline ($154.50), the entire reported tip income counts toward the credit. If you had paid the employee less than $5.15 per hour in cash (which is below the legal minimum, so this rarely happens), the deficit would reduce the qualifying tip portion.
Step four: multiply the qualifying tip portion by the combined employer FICA rate of 7.65%. That is the credit available for that employee, that pay period.
Step five: sum the credit across all tipped employees, all pay periods, for the tax year. The total is your §45B credit, claimed on Form 8846 and carried forward to your business income tax return.
How $9,048 of credit appears on a typical operator's return.
Consider an Italian restaurant with four full-time tipped servers, each averaging 35 hours per week, 50 weeks per year. Each server is paid $7.50 per hour in cash wages and earns approximately $35,000 per year in reported tips. Total tip income across the four servers: $140,000.
Each server worked 1,750 hours in the year. At the §45B baseline of $5.15/hour, the minimum-wage-equivalent figure is $9,012.50 per server. Each server's actual cash wages of $7.50 × 1,750 = $13,125 exceed that baseline, so the entire tip income qualifies for the credit calculation.
Combined employer FICA rate: × 7.65%
§45B credit before adjustment: $ 10,710
Less: §3121(q) deemed-FICA on unreported tips (if any): — $0
§45B credit, claimed on Form 8846: $ 10,710
That credit reduces the restaurant's federal income tax bill by $10,710 — a dollar-for-dollar offset, not a deduction-from-income figure. For an S-corp restaurant whose owner is in the 24% federal bracket, the equivalent ordinary-deduction figure would need to be roughly $44,625 to produce the same net benefit. A typical four-server restaurant, missing this credit for five consecutive years, has left $53,550 on the table — enough to fund a kitchen retrofit, an espresso machine, or a year of paid medical leave for the staff.
Why your accountant may not have mentioned it.
The credit is straightforward enough that experienced restaurant CPAs claim it as routinely as they reconcile bank accounts. The reason it gets missed is almost always one of three things, and recognizing which applies to your situation is most of the work of fixing it.
The first reason: your tax preparer does not specialize in restaurants. A general-practice CPA who handles fifty Schedule Cs a year, two LLCs, and one restaurant client will be competent at most things and unfamiliar with §45B specifically. The credit lives in the niche of restaurant accounting where industry-specific knowledge produces money. A preparer whose practice doesn't include other restaurants will not have a procedure for surfacing it; they will not ask for the data; and they will produce a return that looks correct but is in fact incomplete. The fix is to either work with a preparer who has at least five active restaurant clients — they will run the credit by default — or to come to your existing preparer with the credit already calculated and ready to claim.
The second reason: the data lives in your payroll system, not your bookkeeping system. §45B requires hour-by-hour, employee-by-employee tip and wage data that is in your payroll records but typically isn't on the P&L your CPA gets at year-end. A preparer who works only from QuickBooks reports cannot calculate the credit. The fix is to give your preparer the year-end tip-and-wage report from your payroll provider — Gusto, ADP, Paychex, and similar systems all produce this report on demand under names like "FICA Tip Credit Report," "Tipped Employee Summary," or "Form 8846 Worksheet." If your payroll provider doesn't have a built-in report, the data is still available; it just requires twenty minutes of export work from the platform's wage reports.
The third reason: you switched accountants and the new one didn't know to ask. Many restaurant credits are claimed because one CPA established the practice years ago and the routine carried forward. When the relationship ends and a new preparer takes over, the new preparer doesn't see what was being done — they see this year's P&L and last year's return. If last year's return claimed the credit, it shows up as a line on the prior-year tax form, but if the prior CPA made a mistake or skipped a year, the new CPA has no way to know what should be there. The fix here is the same: come to the engagement with the credit pre-calculated.
Three years back, possibly.
If you have not been claiming §45B and you discover that you should have been, the question is whether you can recover the missed credit from prior years. The answer, generally, is yes — for the most recent three tax years, by filing an amended return on Form 1120-S or 1120 (depending on entity) with a Form 8846 attached. The IRS's standard statute of limitations on amended returns runs three years from the original filing date, and §45B claims made within that window are routinely accepted.
The amendment process is straightforward. Your CPA prepares a corrected return for each affected year, with the additional credit shown, and files it. The IRS processes the amendment, issues a refund or applies the credit against current-year tax, and the matter closes. Most restaurant CPAs who specialize charge $300–$700 per amended year for this work; on a credit recovery of $7,000–$15,000 per year, the cost-benefit is overwhelming.
One caveat: amending a return to claim §45B does sometimes invite a closer IRS look at the underlying tip-reporting practices. This is a feature, not a bug, in the sense that a restaurant with clean tip-reporting practices has nothing to hide and a restaurant with sloppy ones should be cleaning them up regardless. If your tip allocations are tight, your tip pool is documented, and your Form 8027 (the annual large-food-and-beverage establishment tip allocation report) has been filed correctly, the amendment is routine. If any of those are messy, fix them before you amend.
What to do this week.
If you have not previously claimed §45B and you operate a full-service restaurant, three actions are worth taking in the next seven business days.
First, pull your most recent Form 1120-S or 1120 — last year's tax return — and check whether Form 8846 is attached. If it isn't, the credit was not claimed for that year. If it is, verify the credit amount is roughly proportional to your tip volume (at the back-of-envelope rate of 7% to 7.5% of total reported tips). A return showing $400 of §45B credit on $300,000 of tip income has either an error or a specific reason for the mismatch that your preparer should be able to explain in one sentence.
Second, request a "Form 8846 Worksheet" or "FICA Tip Credit Report" from your payroll provider for each of the past three calendar years. This is a standard report; expect to receive it within 24 hours of the request. The data on those reports — tip income, hours worked, cash wages paid — is everything your CPA needs to calculate the credit.
Third, if the past-year credit was not claimed, schedule a 30-minute call with a restaurant-specialized CPA. UpCounsel, your state CPA society's industry-specialty referral list, or a member-recommendation in r/restaurantowners will produce candidates. The conversation is brief: "I've never claimed §45B. I want to amend the past three years and start claiming it going forward. What does that cost?" Get one or two quotes and decide.
Most operators we have worked with through this process recover four-figure to five-figure refunds on the prior-year amendments and convert the credit into an annual line item going forward. The total time investment is roughly four hours of your attention plus your CPA's billable work. The return on that time, in any reasonable accounting, is the highest hourly rate you will ever earn from your business.
