I have used paycheck stubs dated on, or close to but no later than,
Apr 15, Jun 15, Sep 15, and then the total amount on W-2. You
do not need nor use a Dec 31 or Jan 15 paycheck stub.
Doing it this way is not exact, but anything else is even less exact.

Q. for practitioners -- have you seen a segmented 2210 audited?
What did they want for the witholding tax data, and how did they
treat it?

This can add up to significant dollars (e.g. a mid-level TP might
save $500 by preparing an optimal 2210).

year. Personally I would use the full witholding on the first
paycheck even if it included last year's income (unless it was
obvious), and then apply the remainder of the yea'rs withholding in
the 4th quarter. (so the total matches your W-2)... Mark the
appropriate box on 2210. If you are trying to reduce or avoid a
penalty you would have with the Regular Method, use the AI method.

You either apply 1/4 of the annual withholding to each of the ES periods
(yes, I know they're not equal) or you apply withholding to the periods when
it was actually withheld. IOW, paystubs.

When filling out form 2210 (underpayment of estimated tax), the
regular method (part IV), line 19 (estimated tax paid and withheld)
how do you handle withholding?

The instructions say

<Quote
For withheld federal income tax and excess social security or tier 1
railroad retirement tax (RRTA), you are considered to have paid one-
fourth of these amounts on each payment due date unless you can show
otherwise.

If you treat withholding as paid for estimated tax purposes when it
was actually withheld, you must check box D in Part II and complete
and attach Form 2210 to your return.

</Quote
So it seems you can divide your withholding and excess social security
by four and be done with it. In a way this does not make sense
because the first quarter is 3 months, the second quarter is 2 months,
the third quarter is 3 months, the fourth quarter is 4 months, but I
guess that's what the law says.

But what about "unless you can show otherwise"? Your federal (and for
that matter state) tax withheld may have dropped during the year
because you had a paycut or lost your job, and/or you increased your
401K contributions (probably a good way to pick up stocks on the
cheap). Is the some formula one could use, like divide withholding by
x1 for quarter 1, by x2 for quarter 2, etc?

Second, if you count withholding as an estimated payment, meaning that
your 4/15 paycheck counts towards your Q1 payment, then what about
your 1/15 paycheck from the following year? Does it count towards
your Q4 payment? If so, we have the possibility of double=dipping,
because the 1/15 payment of next year also counts for Q1 of next
year's form 2210.
