Tax year 2026 is seven and a half months in. W-2 Box 12 Code TP (qualified tips) and Box 14b TTOC (Treasury Tipped Occupation Code) have been mandatory since January 1, 2026. The final regulations governing these requirements took effect June 12, 2026, following the April 13, 2026 publication of the final rules in REG-110032-25.
Most payroll teams configured their Code TP and TTOC setup in January 2026 and have not revisited it since. That is a problem for four specific reasons.
First, the final regulations added three occupations to the qualified tipped occupation list that were not in the proposed regulations most payroll systems were configured from: visual artists (TTOC 509), floral designers (TTOC 510), and gas pump attendants (TTOC 810). Employees in these roles have been incorrectly coded for seven-plus months.
Second, the SSTB (Specified Service Trade or Business) exclusion eliminates the qualified tips deduction entirely for employees of accounting firms, law firms, financial services companies, consulting firms, and health service businesses, regardless of occupation. RSM specifically identified this as "the one most people miss." Controllers at professional services firms need to audit whether they set up Code TP at all, and if they did, reverse the setup.
Third, Code TP creates a nondeductible wages book-tax difference under the same mechanics as Code TT (qualified overtime) under Section 225. The wages equal to the qualified tip deduction cannot be deducted by the employer. For large hospitality employers, this is a material permanent difference that must be reflected in the ASC 740 effective tax rate, and most have not reflected it in their Q2 or Q3 provision.
Fourth, employees who receive both qualified tips and FLSA-required overtime must have both Code TP and Code TT on the same W-2. Payroll systems configured these as separate processes, and the audit question is whether both codes populate correctly on the same pay run.
This post covers the mechanics of Code TP and TTOC, the four compliance gaps, the mid-year audit process, and the ASC 740 provision implications that no other published guide has addressed.
What Is W-2 Box 12 Code TP and Box 14b TTOC and Why Are They Now Mandatory?
IRC Section 224, enacted by the OBBBA on July 4, 2025, provides a deduction for qualified tip income received by employees in certain tipped occupations during tax years 2025 through 2028. The deduction is claimed by the employee on their individual income tax return and reduces taxable income by the amount of qualifying tips received, subject to MAGI phase-outs.
To claim the deduction, the employee's W-2 must reflect two specific data points that the employer is responsible for populating.
Box 12 Code TP: the amount of qualified tips the employee received during the calendar year. This is the dollar amount of tips in qualifying occupations that are eligible for the Section 224 deduction. It is coded separately from total wages and from Code TT (qualified overtime) in Box 12.
Box 14b TTOC: the Treasury Tipped Occupation Code, a three-digit code assigned by Treasury to each qualifying occupation. The TTOC identifies the specific occupation that qualifies the employee's tips for the Section 224 deduction. The TTOC must appear in Box 14b of the W-2, a new box added specifically for this purpose in the January 9, 2026 W-2 instructions.
Both fields are mandatory for 2026 W-2s. Per RSM's analysis of the final regulations: "two things have to be right" on every tipped employee's W-2, the Code TP dollar amount in Box 12 and the correct TTOC three-digit code in Box 14b. If either is wrong or missing, the employee cannot claim the Section 224 deduction.
The deduction amount for the employee: the Section 224 deduction reduces the employee's adjusted gross income by the amount of qualifying tips. There is no stated dollar cap in the statutory text for the tips deduction (unlike the $12,500 cap on overtime under Section 225), but the MAGI phase-out applies. The phase-out begins at $160,000 for single filers and $320,000 for joint filers (confirmed from the final regulations).
The final regulations effective June 12, 2026 (REG-110032-25, April 13, 2026) represent the definitive TTOC list. Payroll systems configured before June 12 using the proposed regulations list may not reflect the final list.
What Changed in the April 13, 2026 Final Regulations That Your January Payroll Setup May Have Missed
The proposed regulations under REG-110032-25, published in late 2025, established an initial list of tipped occupations and their TTOC codes. Most payroll teams configured their Code TP and TTOC setup in January 2026 using that proposed list.
The final regulations published April 13, 2026, and effective June 12, 2026, made two categories of changes to the proposed regulations that have compliance implications for payroll systems configured in January.
The first category of change is the addition of new occupations. Three new occupations were added to the qualifying tipped occupation list that were not in the proposed regulations: visual artists (TTOC 509), floral designers (TTOC 510), and gas pump attendants (TTOC 810). Employees in these three occupations have been working in qualifying roles and potentially receiving qualifying tips since January 2026, but their W-2s have not been coded with Code TP or a TTOC because those occupations were not on the list when the payroll system was configured.
The second category of change is the refinement of occupation definitions. The final regulations provided more precise definitions of certain occupations on the proposed list, which may affect whether specific employees at specific employers qualify. The MP-HR analysis confirmed that payroll teams should verify their occupation-to-TTOC mapping against the final regulations, not just the proposed regulations.
The compliance gap: employees in the three new occupations who have received qualifying tips from January through the current date have no Code TP or TTOC on their year-to-date W-2 records. At December 31, if the payroll system is not corrected before then, those employees will receive W-2s with no Code TP or TTOC, and they will lose the Section 224 deduction for the entire year unless their employer issues corrected W-2cs. The W-2c obligation falls on the employer, just as it does for Code TT understatements under FS-2026-13 (covered in the companion blog in this cluster).
The correction window: the payroll system must be updated to reflect the three new occupations and their TTOC codes before the next pay cycle. For employees in these occupations, the employer should review whether tips received in Q1 and Q2 2026 were captured and should assess the W-2c obligation for the period from January through the system update date.
The Three New Occupations Added in Final Regs: Visual Artists, Floral Designers, Gas Pump Attendants
The three occupations added in the April 13, 2026 final regulations with their confirmed TTOC codes:
TTOC 509, Visual Artists: employees who work in artistic or creative visual media (painters, sculptors, illustrators, graphic artists, photographers) and who customarily receive tips in connection with their services. A gallery employee who receives tips from clients for assisting with purchases or installations would fall under TTOC 509. A staff photographer at a studio who receives tips from clients for photography sessions would be TTOC 509.
The practical question for employers in creative industries: does the employee's work involve direct customer interaction in which the customer voluntarily provides tips? A purely administrative or production role that does not involve direct customer tip-giving does not qualify even if the employee holds the title of visual artist.
TTOC 510, Floral Designers: employees in floral design and arrangement services who receive tips in connection with design or delivery services. A floral designer at a retail florist who receives tips from customers for custom arrangement services or delivery is TTOC 510.
The practical question for employers in the floral and event services industry: floral designers who work for event planners, wedding vendors, or hospitality venues may have tipping relationships with customers or event clients. The employer must assess whether the specific employee's role involves the kind of direct customer relationship in which tips are customarily given.
TTOC 810, Gas Pump Attendants: employees at full-service fueling stations who pump fuel and provide services directly to customers and who receive tips in connection with those services. As of August 2026, full-service gas stations operate primarily in New Jersey and Oregon (the two states that historically prohibited self-service fueling). Employers in those states should review whether their fueling station employees are coded as TTOC 810.
For employers in states other than New Jersey and Oregon: the TTOC 810 classification is unlikely to affect your workforce because self-service fueling is standard. But an employer that operates any full-service fueling as a service offering should assess whether any employee fits the TTOC 810 definition.
What Is the SSTB Exclusion and Why Accounting Firms, Law Firms, and Financial Services Companies Must NOT Report Code TP
The Specified Service Trade or Business (SSTB) exclusion is the compliance gap that RSM specifically identified as "the one most people miss." It operates as a categorical disqualification that applies at the employer level, not the occupation level.
IRC Section 199A defines SSTBs to include businesses in the fields of health, law, accounting, actuarial science, performing arts, consulting, athletics, financial services, brokerage services, investing, investment management, trading, and dealing in securities. If the employer's business is an SSTB, none of its employees' tips qualify for the Section 224 deduction, regardless of whether the employee holds a qualifying tipped occupation.
The RSM analysis confirms the exclusion's scope: an employee of an SSTB who works in a qualifying tipped occupation (for example, a receptionist at an accounting firm who occasionally receives tips from clients, or a server at a law firm cafeteria operated in-house) cannot claim the Section 224 deduction even if the occupation would otherwise qualify.
The practical compliance question for SSTB employers: did your payroll team set up Code TP and TTOC for any employees in January 2026? If yes, those employees have been receiving incorrect W-2 coding. Their W-2s should not include Code TP or a TTOC. The employer must correct the payroll setup before the next pay cycle and must assess whether a W-2c is needed for the year-to-date period if any Code TP amounts were already reflected in year-to-date payroll records.
The SSTB exclusion applies even to large multifaceted employers that operate SSTB and non-SSTB business lines within the same legal entity. A large financial services company that also operates a cafeteria for employees should assess which entity employs the cafeteria staff. If the cafeteria is operated by the financial services entity (an SSTB), the cafeteria servers are employees of an SSTB and their tips do not qualify. If the cafeteria is operated by a separate legal entity that is not an SSTB, the cafeteria servers may qualify.
What Is the Mid-Year TTOC Assignment Audit Your Payroll Team Must Run Now
The mid-year TTOC audit has four specific components, each addressing one of the four compliance gaps identified above.
Audit Component 1: confirm the occupation-to-TTOC mapping against the April 13 final regulations. Pull the current TTOC assignment for every employee who is currently coded as a tipped worker in the payroll system. Compare each TTOC assignment to the final regulations list (not the proposed regulations list). The three occupations to specifically verify:
Has the payroll system been updated to include TTOC 509 (visual artists), TTOC 510 (floral designers), and TTOC 810 (gas pump attendants)?
For each employee currently assigned a TTOC code, does the three-digit code match the correct TTOC for the employee's actual occupation? A bartender must be TTOC 101. A server must be TTOC 102. A musician must be TTOC 201.
Audit Component 2: confirm the SSTB exclusion was applied correctly. Identify every legal entity within the corporate group that is an SSTB under Section 199A. For each SSTB entity, confirm that no employees of that entity have Code TP or TTOC in their year-to-date payroll records. If any do, the setup must be corrected and a W-2c may be required.
Audit Component 3: confirm the Code TP dollar amount is correctly capturing qualifying tips. The Code TP amount must reflect only tips received in connection with TTOC-qualifying occupations. It must not include service charges (which are wages, not tips), mandatory gratuities, or tips received by employees in non-qualifying occupations. Pull a sample of tipped employees and verify that the Code TP amount matches the qualified tip amount for each employee for a representative pay period.
Audit Component 4: confirm the dual Code TP/TT workers are coded correctly. For employees who receive both qualified tips and FLSA-required overtime, verify that both Code TP and Code TT appear in Box 12 of their current-year W-2 records, and that the TTOC appears in Box 14b. This requires running a payroll report filtered for employees with both overtime and tip income and confirming that both codes are present in the year-to-date W-2 data.
How to Handle Employees With Both Code TP (Tips) and Code TT (Overtime) on the Same W-2
Many workers in hospitality, food service, and gaming receive both qualifying tips and FLSA-required overtime in the same pay period. A full-time server at a restaurant may work more than 40 hours in a week and also receive cash or charged tips during that period. That employee's W-2 must reflect both Code TP (the qualifying tip amount) and Code TT (the qualifying overtime amount) in Box 12.
The codes are independent and non-exclusive. Code TP captures the Section 224 tip deduction amount. Code TT captures the Section 225 overtime deduction amount. Both can appear on the same W-2, and both can be claimed by the employee on the same individual return.
The Box 14b TTOC must also appear on the same W-2, identifying the occupation that qualifies the tips. The TTOC requirement is specific to Code TP. Code TT has no corresponding occupation code requirement.
The payroll system configuration question: most payroll systems configured Code TP and Code TT as separate processes within the same pay run. When a tipped employee also worked overtime in the same pay period, the system should generate both codes automatically. The mid-year audit should confirm this is working as designed.
The test: run a payroll register for a two-week period that included both overtime and tip income for at least one employee. Confirm that the employee's pay stub and year-to-date W-2 data shows: (1) regular wages, (2) overtime wages (FLSA-required portion), (3) tips received, (4) Code TP amount in Box 12, (5) Code TT amount in Box 12, and (6) TTOC code in Box 14b. If any of these six items is missing from the employee's record, the payroll system configuration is incomplete.
The Beancount.io guide from June 4, 2026 is the most specific published reference on the dual TP/TT worker scenario. It confirms that employers with multiple role workers (employees who work in qualifying tip roles and also earn FLSA overtime) must ensure both codes are reported in the same W-2 issuance cycle and that the TTOC in Box 14b correctly identifies the tipped occupation even when Code TT is also present.
The ASC 740 Book-Tax Difference: Why Qualified Tip Wages Create a Nondeductible Expense That Must Flow Through Your Tax Provision
This is the ASC 740 implication that has received no published guidance and that is material for large hospitality employers, gaming companies, and restaurant groups.
The mechanics mirror those of the Section 225 overtime deduction (Code TT) discussed in the companion blog from this cluster. Under the OBBBA, employers cannot deduct the portion of wages equal to the qualified tip deduction claimed by employees. The same nondeductibility rule that applies to Section 225 qualified overtime also applies to Section 224 qualified tips.
Specifically: if an employee receives $10,000 in qualifying tips and claims the Section 224 deduction on their individual return, the employer cannot deduct the $10,000 of wages paid in connection with those qualifying tips. The wages are deductible under normal tax rules (they are ordinary and necessary business expenses), but the $10,000 that corresponds to the employee's deduction is disallowed at the employer level.
The accounting consequence: this nondeductible wage expense creates a permanent book-tax difference. The wages are expensed in full under GAAP. For tax purposes, the wages are only partially deductible (the portion not equal to the employee's qualified tip amount). The nondeductible portion is a permanent difference, meaning it does not reverse in future periods.
Under ASC 740-10-30, permanent differences affect the effective tax rate in the period they arise. For a large restaurant group with $50 million in annual qualified tip wages, the permanent difference adds approximately $10.5 million to taxable income relative to book income (at a 21% corporate tax rate, this increases tax expense by approximately $2.2 million compared to a world without the nondeductibility rule). This is a material permanent difference that must be reflected in the AETR under ASC 740-270 and in the rate reconciliation table disclosed in the annual ASC 740 footnote.
The Q3 2026 provision implication: if this permanent difference was not reflected in the Q1 and Q2 provisions, the Q3 provision must catch up. The AETR calculation under ASC 740-270-30-2 must reflect the year-to-date nondeductible qualified tip wages through Q3. Tax directors at hospitality employers should specifically confirm that the Code TP nondeductibility is captured in the provision model as a permanent difference, not as a timing difference that will reverse.
What Is the W-2c Correction Liability If TTOC Codes Are Wrong at Year-End?
The W-2c correction obligation for Code TP errors mirrors the obligation described for Code TT in the companion blog from this cluster. FS-2026-13 confirmed that the Code TT mandatory reporting rule applies without self-reporting alternatives. The same principle applies to Code TP: if the TTOC or the Code TP dollar amount is wrong on the W-2, the employee cannot claim or cannot correctly claim the Section 224 deduction absent a corrected W-2c.
The specific W-2c scenarios for Code TP:
Wrong TTOC: the employer assigned TTOC 101 (bartender) to an employee who is a server (TTOC 102). The employee's Section 224 deduction claim on their individual return references a TTOC that does not match the code on their W-2. The IRS may flag this inconsistency in its correspondence audit process. The employer must issue a W-2c with the correct TTOC.
Missing TTOC: the employer set up Code TP in Box 12 but did not populate Box 14b with any TTOC code. Without the TTOC, the IRS cannot verify that the employee's occupation qualifies for the Section 224 deduction. The employer must issue a W-2c adding the TTOC.
Wrong Code TP amount: the employer captured total tips but not only qualifying tips (for example, included service charges which are wages, not tips, in the Code TP amount). The overstated Code TP amount may result in an overstated employee deduction. A W-2c correcting the Code TP amount downward is required.
SSTB error: the employer is an SSTB and incorrectly reported Code TP and TTOC. A W-2c removing Code TP and the TTOC, with a corrected zero amount, must be issued.
Each W-2c adds cost: the filing fee for W-2c corrections, the employee notification requirement, and the potential for the employee to need to file an amended return. For large employers with thousands of tipped workers, a systematic TTOC error discovered in November creates a large-volume W-2c project with a compressed timeline before the W-2 issuance deadline of January 31, 2027.
A Mid-Year Code TP Compliance Checklist for Controllers
Eight specific items to confirm before the next pay cycle:
One: pull the current TTOC list from the payroll system and compare it to the April 13, 2026 final regulations list. Confirm that TTOC 509 (visual artists), TTOC 510 (floral designers), and TTOC 810 (gas pump attendants) are in the system. For any employees in these three occupations who have received tips since January, assess the W-2c obligation for uncoded periods.
Two: confirm the employer is not an SSTB under Section 199A. For diversified employers with multiple legal entities, confirm the SSTB determination is made at the entity level, not the consolidated group level. If any entity is an SSTB, ensure no Code TP or TTOC is being reported for employees of that entity.
Three: run a report of all employees with TTOC codes assigned and verify that each employee's actual job title matches the assigned TTOC. A mismatch between job title and TTOC is the most common TTOC assignment error and the most difficult to detect without a systematic cross-reference.
Four: confirm the Code TP dollar amount population logic. Code TP must include only qualifying cash tips and credit card tips distributed to the employee in connection with TTOC-qualifying services. It must not include mandatory service charges, employer-allocated tips (which are wages), or tips received in non-qualifying occupations.
Five: confirm that dual TP/TT employees have both codes in their year-to-date W-2 records. Run a report filtered for employees with overtime income and tip income in the same pay period and verify that both Code TP and Code TT appear in the W-2 data.
Six: confirm the Box 14b TTOC field is being populated in the W-2 output. Some payroll systems calculate Code TP correctly but do not write the TTOC to the Box 14b field in the W-2 data file. A test W-2 output for a tipped employee should be reviewed to confirm Box 14b shows the three-digit TTOC.
Seven: quantify the Code TP nondeductible wages amount year to date and confirm it is reflected as a permanent difference in the ASC 740 provision model. If it is not, the tax director must add it to the Q3 AETR calculation.
Eight: confirm the year-to-date Code TP amounts are consistent with tip income reported on the employer's payroll tax filings (Form 941). Code TP amounts for the year should reconcile to the tip income reported to the IRS on the quarterly 941s. A material discrepancy between the two may signal a system configuration error.
Frequently Asked Questions
What is W-2 Box 12 Code TP?
W-2 Box 12 Code TP reflects the dollar amount of qualified tips an employee received during the calendar year in a Treasury Tipped Occupation. The amount is the basis for the employee's Section 224 deduction on their individual income tax return. Code TP was added to the W-2 for tax year 2026 under the OBBBA, enacted July 4, 2025.
What is the Treasury Tipped Occupation Code (TTOC)?
The TTOC is a three-digit code assigned by Treasury to each qualifying tipped occupation under Section 224. The TTOC appears in Box 14b of the W-2. The final TTOC list was published in IRS final regulations REG-110032-25 (April 13, 2026, effective June 12, 2026) and includes more than 70 occupations across eight categories, including food service workers (TTOC 101-199), performing artists (TTOC 201-299), personal care workers (TTOC 401-499), and others.
Which occupations were added in the April 2026 final regulations?
Three occupations were added in the April 13, 2026 final regulations that were not in the proposed regulations: TTOC 509 (visual artists), TTOC 510 (floral designers), and TTOC 810 (gas pump attendants). Payroll systems configured before June 12, 2026 using the proposed regulations list may not include these three occupations.
Does the no tax on tips deduction apply to employees of accounting or law firms?
No. The SSTB exclusion under Section 199A eliminates the Section 224 deduction for all employees of Specified Service Trades or Businesses, including accounting firms, law firms, financial services companies, health service businesses, and consulting firms, regardless of the employee's occupation. RSM confirmed this as the most commonly missed compliance requirement.
What happens if the employer reports the wrong TTOC on an employee's W-2?
The employee may be unable to correctly claim the Section 224 deduction, or the IRS may flag the discrepancy in a correspondence audit. The employer must issue a corrected Form W-2c with the correct three-digit TTOC code. The W-2c is filed with the Social Security Administration and provided to the employee.
Do tipped employees who also earn FLSA overtime get both Code TP and Code TT?
Yes. Code TP and Code TT are independent and non-exclusive. An employee who receives qualifying tips and also works more than 40 hours in a workweek (generating FLSA-required overtime) receives both codes in Box 12 of the same W-2. The TTOC also appears in Box 14b. Both codes are required for the employee to claim both the Section 224 and Section 225 deductions.
Does Code TP create a nondeductible expense for the employer?
Yes. The employer cannot deduct the portion of wages equal to the qualified tip amount the employee deducts under Section 224, following the same mechanics as the Section 225 overtime nondeductibility rule. This creates a permanent book-tax difference that must be reflected as a permanent difference in the employer's ASC 740 income tax provision.
Key Takeaways
- W-2 Box 12 Code TP (qualified tips) and Box 14b TTOC (Treasury Tipped Occupation Code) have been mandatory since January 1, 2026. The final regulations (REG-110032-25, April 13, 2026, effective June 12, 2026) added three new occupations not in the proposed regulations: visual artists (TTOC 509), floral designers (TTOC 510), and gas pump attendants (TTOC 810). Payroll systems configured before June 12 may be missing these occupations.
- The SSTB exclusion (Section 199A) eliminates the Section 224 qualified tips deduction for all employees of accounting firms, law firms, financial services companies, health service businesses, and consulting firms, regardless of occupation. This is the most commonly missed compliance requirement per RSM's analysis.
- Employees who receive both qualifying tips and FLSA-required overtime must have both Code TP and Code TT in Box 12 of the same W-2, along with the TTOC in Box 14b. The two codes are independent and non-exclusive.
- Code TP creates a permanent book-tax difference: the employer cannot deduct wages equal to the employee's qualifying tip deduction amount. For large hospitality employers, this is a material permanent difference that must be reflected in the ASC 740 AETR. Tax directors who have not yet incorporated this permanent difference must add it to the Q3 provision.
- Wrong TTOC codes, missing Box 14b entries, and SSTB errors each require a corrected Form W-2c. The W-2c must be issued by the employer; the employee has no self-help remedy for incorrect or missing Code TP or TTOC entries, consistent with the mandatory reporting rule confirmed for Code TT under FS-2026-13.
- The mid-year audit must cover: TTOC mapping against the April 13 final regulations (including the three new occupations), SSTB exclusion confirmation at the entity level, Code TP dollar amount accuracy (tips only, not service charges), dual TP/TT worker coding, Box 14b population in the W-2 output, Code TP permanent difference in the ASC 740 provision, and Form 941 reconciliation.
