This thread is very funny to me.
Real world answer, vs the correct and legal answer.
What is the dollar amount difference in sales and in tax?
Under paying sales tax by intentional means is fraud, but in this case you would still be paying in every dollar of sales tax collected.
Selling 100k, collecting 25k, saying you sold 80k and paying in only 20k = fraud.
Selling 100k, collecting 20k, reporting 80k to match the amount collected… illegal yes, but not sure if it would constitute fraud, as you are not keeping the extra money (defrauding the state)
The company should own up to their mistake and eat the difference.
I would not want my name on a sales tax return that understated gross sales or sales tax due.
Also, keep in mind if you understate for a sales tax return, you will also have to understate on the income tax return.
The states compare sales tax returns to income tax returns, and issue audit notices if there are material discrepancies.
I had a similar situation when NYS was bouncing around with their sales tax rates a few years back and I made the client eat the difference.
It was not a very large tax amount. I considered it a stupidity tax for not collecting at the proper rate.
But, how about this one.
Lets say the client collected at 10%, but they should have only collected at 8%.
Do you over report gross sales to match the 10% and thereby not withhold any of the extra sales tax you collected?
Or do you report actual gross sales, pay the correct 8% and the client gets to keep the additional 2%? Thereby keeping funds that belong to the state?
Or… do you report the actual gross, pay in the actual tax collected, and let the client get a sales tax audit (so you get more billable hours…)
So many ethical dilemmas…
