For some reason this formula picks up 25% portion.

Based on the IRS publication it should be at the 15%? What am I doing wrong

Maybe try a different approach. Take a look here.

First, you are talking about federal withholding for biweekly
payment. The term "federal tax" usually refers to the 1040 tax rate
schedule.

Second, you have some obvious typos and other anomalies, no doubt left
over from your development efforts. In the 15% term, "1445" should be
CD7 (which you say is 1440), and "1*" should be "$M$17*".

Looks to me that the 1445 typo is the root cause of the problem.

Note that 1440 - 134.62 is 1305.38, very near the top of the 15%
bracket. Your corrected formula computes withholding of 165.81, which
is very close to the highest withholding for the 15% bracket
(165.90). With your typo (1445 instead of 1440), the computed
withholding is 166.56. I presume that is what you mean "pick[ing] up
[a] 25% portion".

I might also note that you should round the final amount at least to
the penny. Other rounding options are permitted, per IRS Pub 15, as
you may know.

Don't rely on Excel's formatting to display the rounded amount. The
underlying value still has higher precision. That might throw off
dependent calculations, if any.

Your formula is, frankly, too complicated for me. But I would never
think to implement these sorts of calculations in any way but by a
VLOOKUP table. The great benefit of doing it that way is that the
table (which changes yearly) is separated from the formula (which
should never change). Define the table as a name and use the name in
the formula, and then you never change the formula even if the table
grows by a row.
