FICA taxes — Social Security (6.2%) and Medicare (1.45%) — apply to all tip income regardless of the OBBBA tips deduction. On $40,000 in tips, FICA totals $3,060. The OBBBA reduces income tax on tips; it does not reduce FICA. Tips over $20/month must be reported to your employer.

Key Facts
FICA Rates on Tips: 6.2% + 1.45%
Social Security tax: 6.2% on all tip income, up to the Social Security wage base of $176,100 for 2025. Medicare tax: 1.45% on all tip income with no cap. Additional Medicare surtax: 0.9% for income above $200,000 (single) or $250,000 (MFJ). On $40,000 in tips: Social Security = $2,480 (6.2%) + Medicare = $580 (1.45%) = $3,060 total FICA. This is unchanged by the OBBBA.
How FICA Is Collected on Tips
Tips over $20 per month must be reported to your employer by the 10th of the following month using IRS Form 4070. Your employer adds reported tips to your wages for FICA withholding purposes, withholding 6.2% SS and 1.45% Medicare from your next paycheck. Your employer also pays a matching 7.65% FICA on your tip income. If tips exceed your next paycheck amount, the uncollected FICA is reported on your W-2 in Boxes 12a/12b with codes A and B — you pay it when you file your federal return.
OBBBA Tips Deduction Reduces Income Tax Only
The OBBBA tips deduction reduces your federal adjusted gross income (AGI) by up to $25,000. This reduces federal income tax — which is calculated on AGI. FICA is not calculated on AGI. FICA is calculated on gross wages and tips as earned. The two tax systems are independent. The OBBBA gives an income tax break; it does not give a FICA break.
What You Actually Owe on $40,000 in Tips (2026)
Server, single filer, $40,000 in tips, 22% federal bracket: FICA on tips = $3,060 (6.2% SS + 1.45% Medicare). Federal income tax on $40,000 tips BEFORE OBBBA deduction: approximately $8,800 (22% on amount above standard deduction threshold). Federal income tax on $40,000 tips AFTER $25,000 OBBBA deduction: approximately $3,300 (22% on the remaining $15,000). FICA bill: $3,060 either way. Total tax on tips: approximately $6,360 after OBBBA vs $11,860 before OBBBA. Significant income tax savings — but FICA is the constant.
Employer FICA Match and Section 45B Credit
Your employer pays matching FICA of 7.65% on your tip income. Large food service employers can claim a Section 45B FICA tip credit on their federal business return — a tax credit equal to the employer's FICA paid on tips above the federal minimum wage. This credit incentivizes employers to accurately report tip income to the IRS, which benefits workers by ensuring accurate Social Security records. The credit does not reduce the employee's FICA obligation.
Introduction
FICA Applies to Tips — Even After the OBBBA
The One Big Beautiful Bill Act (OBBBA) gives tipped workers a federal income tax deduction of up to $25,000 on tip income — reducing what you owe the IRS at tax time. But FICA is a separate federal payroll tax, collected by your employer each pay period, and the OBBBA does not touch it. Social Security and Medicare taxes apply to every dollar of tip income you earn in 2026, just as they always have. This guide explains exactly how FICA applies to tips, what you owe, how it is collected, and how it differs from the income tax savings the OBBBA provides.
Section 01
How FICA Is Withheld on Tip Income
The mechanics of FICA withholding on tips involves a two-step process — reporting tips to your employer, then having FICA withheld from your paycheck.
The $20/Month Reporting Threshold
If you receive more than $20 in tips in any calendar month, you must report the total tip amount to your employer by the 10th of the following month. Use IRS Form 4070 (Employee's Report of Tips to Employer) or an equivalent employer form. Tips of $20 or less per month are not required to be reported, but are still technically taxable income.
How Your Employer Withholds FICA on Tips
Once you report tips, your employer adds them to your regular wages for FICA purposes and withholds the combined 7.65% from your next available paycheck (6.2% Social Security + 1.45% Medicare). If your tips exceed your available paycheck — common for workers with high tips and lower base wages — the uncollected FICA is carried forward. At year-end, uncollected Social Security tax appears in W-2 Box 12a (code A) and uncollected Medicare tax in Box 12b (code B). You pay this uncollected FICA with your federal tax return.
Credit Card vs Cash Tips — Same FICA Treatment
Both credit card tips and cash tips are subject to FICA. Credit card tips processed through point-of-sale systems are automatically reported to your employer. Cash tips must be reported by you using Form 4070. The FICA rate is identical regardless of whether tips were paid in cash or by card.
Section 02
Allocated Tips and W-2 Box 8
If you report fewer tips than 8% of your share of the employer's gross receipts, the IRS requires the employer to allocate additional tips to you on your W-2.
What Allocated Tips Mean
Allocated tips (shown in W-2 Box 8) represent the IRS's estimate that you received more tips than you reported. Allocated tips are NOT subject to FICA withholding by the employer at the time of allocation — but you must report them as income on your federal and state returns (Schedule 1) and pay FICA on them yourself.
How to Handle Allocated Tips
If your contemporaneous tip records (your daily log) show that you actually received fewer tips than the allocated amount, you can use your records to dispute the allocation on Form 4137 (Social Security and Medicare Tax on Unreported Tip Income). Your log takes precedence over the employer's allocation formula if properly maintained.
Form 4137: Calculating FICA on Unreported Tips
If you did not report all tips to your employer and the unreported amount exceeds $20/month, you must complete Form 4137 with your federal return. This form calculates the FICA owed on unreported tips — both the employee share (7.65%) and the employer share (also 7.65%) since the employer did not withhold. The combined rate on self-reported unreported tips is 15.3% — the same as self-employment tax. Accurate daily reporting avoids this situation entirely.
Section 03
FICA and Social Security Benefits: The Long-Term Connection
FICA on tips is not purely a cost — it builds your future Social Security retirement benefit.
Tips Build Social Security Credits
Every dollar of tip income properly reported and subject to FICA is counted in your Social Security earnings record, which determines your future retirement benefit. In 2026, you earn one Social Security credit for every $1,730 in covered earnings (wages plus reported tips), up to 4 credits per year. Workers who accurately report tip income build higher Social Security benefits over their careers than workers who underreport. The long-term benefit of accurate FICA reporting is a higher monthly Social Security check in retirement.
Unreported Tips Cost You in Retirement
A server who underreports $10,000/year in tips over a 30-year career has $300,000 in earnings not reflected in their Social Security record. Depending on their earnings history, this could reduce their monthly Social Security benefit by $200-$400/month in retirement — a lifetime cost of $48,000-$96,000 for the average retiree living 20 years past retirement. The short-term FICA savings from underreporting are far smaller than the long-term benefit loss.

Does the OBBBA no tax on tips deduction also eliminate FICA?
No. The OBBBA tips deduction reduces federal income tax only — it has no effect on FICA. Social Security (6.2%) and Medicare (1.45%) taxes apply to all tip income regardless of any income tax deduction. On $40,000 in tips, FICA totals $3,060 whether or not you claim the OBBBA deduction.
Q
How much FICA do I pay on $30,000 in tips?
On $30,000 in tips: Social Security = $1,860 (6.2%) + Medicare = $435 (1.45%) = $2,295 total FICA. This applies regardless of any deductions. Your employer withholds this from your paychecks after you report tips via Form 4070. If your tips exceed your paycheck, uncollected FICA appears in W-2 Boxes 12a/12b.
Q
What is the threshold for reporting tips to my employer?
Tips exceeding $20 in any calendar month must be reported to your employer by the 10th of the following month using IRS Form 4070. Tips of $20 or less per month are technically taxable but not required to be reported. Most tipped workers exceed the $20/month threshold on almost every working day — report all tips promptly.
Q
What are allocated tips on my W-2?
Allocated tips (W-2 Box 8) are additional tip income the IRS estimates you received but did not report, calculated as 8% of your share of the employer's gross receipts. If your reported tips are less than this 8% threshold, your employer allocates the difference. Allocated tips are included in taxable income, and you owe FICA on them via Form 4137. A contemporaneous daily tip log can be used to dispute allocations.
Q
Does reporting more tips hurt me because I pay more FICA?
In the short term, yes — more reported tips means more FICA withheld. But accurate reporting builds your Social Security earnings record, which determines your future retirement benefit. A server who underreports $10,000/year over 30 years could lose $200-$400/month in Social Security in retirement — far exceeding the short-term FICA savings. Accurate reporting is in your long-term financial interest.
