Tie-Out Press
Current as of 4 October 2026.
Each entry below is one of four things: a change to the statute, IRS guidance or Form W-2 instructions that bears on the 2026 code TT figure; a sentence on a payroll vendor's published page that differs from the primary source, set beside it; a re-issue of the payroll-vendor map; or a new version of the imprint's own Qualified Overtime Kit, stated as what changed and whether any figure changed. Entries run newest first. Each quotes its sources, with the date they were read; where they differ, the primary source governs. Nothing here says how any payroll product behaves. The 24 September 2026 entry is of the second kind.
Every change to the TY2026 code TT treatment as it happens, and the payroll-vendor map re-issued when a vendor's documentation moves. Messages go out when something changes; there is no schedule. Some will mention or link to the imprint's own paid editions.

The Qualified Overtime Kit's workbook is at 1.0.2 under the tag ty2026-v1.0.2, dated 30 September 2026. No figure changed. The engine and the constants file, params/ty2026.json, last amended 2026-09-20, are the ones 1.0.0 shipped, and a figure computed with 1.0.0 or 1.0.1 stands. Four things changed, all packaging or wording. Every download now carries LICENSE.txt, the license terms as the kit's page states them, and a README.txt of its own, true of that download alone; no earlier download carried the license. In the paid download the constants file sits at params/ty2026.json, the path the workbook and every page name, where 1.0.1 packed it as constants/ty2026.json. The About sheet said that every one of the suite's 90 test cases is compared to the cent against the Python engine. 85 are; 3 are held as invariants on the Lookups and Checks sheets, and 2 have no Excel expression and are named and not compared. That sentence and three like it now take their counts from the test suite, as the parity table on the kit's page already does. The second license cell's named range is now Order_Number, matching its label, and the 1.0.0 and 1.0.1 rows that said both license cells arrive empty are corrected in place: they do in the paid file, and in the free sample both carry the sample marking. The workbook's Version sheet records each. The download link on a Lemon Squeezy receipt serves 1.0.2 from the date above, and the three free files on the kit's page are the 1.0.2 build from the same date. Nothing was sent to the errata list, because no figure changed.
The Qualified Overtime Kit's workbook is at 1.0.1 under the tag ty2026-v1.0.1, dated 28 September 2026. No figure changed. The engine and the constants file, params/ty2026.json, last amended 2026-09-20, are the ones 1.0.0 shipped, and a figure computed with 1.0.0 stands. Two things changed. On the free sample, the Sample Client sheet no longer freezes the 28 rows above its twelve employees, which kept them from scrolling into view; it now freezes columns A to C and no rows. On the About sheet of every build, the second license cell is labeled Order number, where 1.0.0 said License key, because nothing reads a key and the order number on the receipt is what a support request quotes. The Method Memo prints Order number where it printed License key, and both cells still arrive empty in the file you buy. The workbook's Version sheet records both. The download link on a Lemon Squeezy receipt serves 1.0.1 from the date above, and the three free files on the kit's page are the 1.0.1 build from the same date. Nothing was sent to the errata list, because no figure changed.
The code TT rules have not changed. Below are four vendor sentences that differ from the statute or IRS guidance, found while compiling edition 1 of the map (pages read 24 September 2026). The primary source controls. The About Form W-2 page lists three IRS changes to the 2026 Form W-2 or its instructions since August (8 September: box 10 dependent care exclusion corrected from $5,000 to $7,500); none concerns box 12 or code TT.
The QuickBooks article "Impact of the No Tax on Overtime provision to QuickBooks Payroll" (updated 25 August 2026) says: "To find other calculation solutions where overtime pay is calculated more generously than the FLSA rules see: IRS Notice IR-2025-114." It adds: "While this notice was released to help with 2025 amounts, the rules and examples can be used in future years". IR-2025-114 is a 21 November 2025 news release, not a notice. It announced Notice 2025-69, whose Section III is headed "GUIDANCE FOR TAX YEAR 2025". FS-2026-13 (6 August 2026) calls the notice 2025-only; its 2026 rule, A16, says the employer "must evaluate the payments in accordance with the FLSA's principles at 29 USC § 207, particularly subsections (e) and (h), to determine the amount required under the FLSA." No IRS document read extends the 2025 methods to 2026.
Action: Check that no 2026 code TT figure was computed with a Notice 2025-69 approximation method.
Xero's US guide "New overtime, minimum wage & payroll law changes small businesses must know in 2026" (published 2 July 2026; not a Xero Payroll help page) says: "The deduction is available to W-2 employees who receive overtime pay under the FLSA or equivalent state laws." IRC §225(c)(1) defines qualified overtime compensation as overtime "required under section 7 of the Fair Labor Standards Act of 1938". FS-2026-13 A4: an individual ineligible for FLSA overtime receives no qualified overtime compensation, whatever other laws provide. A16: "only the amount minimally necessary to satisfy 29 USC § 207 is qualified overtime compensation for purposes of the tax deduction." Overtime paid under a state law qualifies only to the extent the FLSA also required it.
Action: Check that each 2026 code TT figure carries only the premium the FLSA required, whatever a state law required on top.
Paychex's "Top Regulatory Issues for Businesses in 2026" (last updated 12 December 2025) says: "There are caps for the amount ($12,000 for an individual and $25,000 for joint filer) that can be claimed." IRC §225(b)(1): the deduction "shall not exceed $12,500 ($25,000 in the case of a joint return)." Paychex's later pages, including PX2 (30 April 2026), print the statutory figure. The sentence concerns the individual's deduction limit and does not change the code TT figure in box 12. Under FS-2026-13 A10, that figure is the total qualified overtime compensation paid, which may not equal what the employee can deduct; its example reports $30,000 against a $12,500 limit.
Action: Check that client-facing material states the deduction limit as $12,500 (individual) and $25,000 (joint return).
The Paychex article "2025 Tax Law: No Taxes on Overtime and Tips" (last updated 30 April 2026) says: "Guidance is still required on how qualified overtime compensation will be defined, adjustments needed to Form W-4, and what will transition relief be for taxpayers claiming the deduction in Tax Year 2025." The definition has been statutory since 4 July 2025 (Pub. L. 119-21, IRC §225(c)(1)). The 2025 relief is Notice 2025-69, announced 21 November 2025. Employer computation guidance, still pending on 30 April 2026, arrived as FS-2026-13 on 6 August 2026; the sentence does not name it. The Form W-4 clause was not checked. The sentence does not change the code TT figure in box 12.
Action: Check any client-facing line that calls guidance pending against FS-2026-13 (6 August 2026).

What this site records about you. There is no analytics script, no pixel
and no beacon on this page, and it loads nothing from any other site. Requests to it are
counted at Cloudflare's edge, on the request already being served: the path, the host of
the referring site (never the referring address itself), the two-letter country the edge
attaches, and the source tag if the link you followed carried one. Pressing Subscribe
sends the form to this site's own /subscribe path first. The Worker there
reads which page you pressed the button on and which link brought you to it, from that
page's own address and nothing else, writes one row with that source, and answers with a
redirect that makes your browser send the same form on to Kit, the email service that
hosts the list. A sign-up from this page is recorded as the changelog's unless the link
that brought you here carried its own tag. It does not read the form, keep the address,
set a cookie, or record your IP address or your browser's user agent. Kit mails the
confirmation link, and nothing is sent to you until you click it. The counter is
worker/index.js; tools/verify_edge_instrumentation.py runs it
and fails the build if a row ever carries an address.
Tie-Out Press publishes the Qualified Overtime Kit, which reconciles the qualified overtime figure an employer reports in box 12 of the W-2, under code TT. It is a calculation tool, not tax or legal advice.
