Tie-out tool / One-week calculator

Qualified overtime calculator for employers

Enter one workweek. The calculator returns the Code TT amount and shows how it differs from the overtime pay on the register. For a whole year and a whole staff, use the file tool.

Code TT for a workweek = hours worked over 40 x one-half x the regular rate. For someone paid only one hourly rate, the regular rate is that hourly rate. (IRS FS-2026-13, Q12; 29 CFR 778.110(a))

Overtime hours the register paid is what payroll actually paid at a premium that week. If it is more than the hours over 40, the extra is not qualified overtime.

A whole year from a file

One week is the easy part. The year has about 52 workweeks per employee, pay periods that split them, and holidays. The tie-out tool takes a timesheet CSV and the register overtime totals and returns one worksheet per employee, with every week shown.

What this calculator does not handle

Bonuses, tips, salaries and two rates in one week change the regular rate. The calculator and the file tool both stop short of those cases instead of guessing.

Do the whole year from a file

Drop a timesheet CSV, paste the register overtime totals, and get a worksheet per employee with the reason for every difference.

Questions

Is this the same as the employee deduction calculator?

No. Employee calculators estimate the tax deduction. This one computes the amount an employer reports on Form W-2, box 12, code TT.

Does it store my numbers?

No. The arithmetic runs in your browser.
