Payroll Calculation Errors

Payroll teams repeatedly face system miscalculations, missed inputs, and lack of validation, forcing hours of manual error correction and reconciliation.

In their words

I wasnt reviewing payroll. I was fixing minor things every week because I never trusted what was coming out

r/Businessowners on Reddit

They’ve been incorrectly calculating some of our statutory deductions... ADP typically dismisses complaints of double deductions without checking anything

r/humanresources on Reddit

Paychex simply cannot handle our FLSA fluctuating workweek/day-rate overtime math natively, which means I'm doing it all manually in Excel.

r/Payroll on Reddit

They filed an incorrect state annual tax report for 2025 and their solution is to tell me that I need to have them pull about a grand out of our bank a/c to pay the penalty

r/nonprofit on Reddit

They have yet to implement a good system for the OBBB qualified overtime yet for anyone who pays bi-monthly.

r/Payroll on Reddit

We're having to constantly recalculate and revise ourselves, tell them exactly what to do, and they still can't get it right.

r/Accounting on Reddit

I was hired as a casuals at a step 4 rate but have been paid 675 hours at step one.

r/CanadaPublicServants on Reddit

I found out he posted every payroll journal entry wrong. Absolutely everything is screwed up.

r/Accounting on Reddit

I always end up going back through everything one more time because I keep thinking I missed something.

r/humanresources on Reddit

Turns out supervisor was fixing someone else's stuff and accidentally put me in for 8 hours of AL. I was billed .5 hour AL.

r/USPS on Reddit

so now no one is getting paid until that's sorted

r/ems on Reddit

We keep spreadsheets just in case, remind each other to double check things and leave extra time every payroll day because we expect something to come up

r/managers on Reddit

ChatGPT figured out that it was a penalty rate and dug in for me.
