[net.taxes] increasing exemptions to cover mortgage interest

rkj@ides.UUCP (Rick Janka) (03/06/86)

It is important to discriminate between "deductions" as reported on your
1040 (and worth $1040 each) and "exemptions" as reported on your W-4.  I
have heard the term allowance used instead of exemption, and it is perhaps
more accurate.  The number of exemptions is a personal choice, though the
number of deductions one can claim is fixed by the feds.  

I recommend against using the little formula in computing the number of 
exemptions you claim.  In my case, it resulted in over-withholding, though
in some cases it may be accurate.  I have found that different employers
use different formulas in computing tax withheld.  My past employer used
the table as shown in IRS Pub 15.  My current employer annualizes your
current paycheck (thus to include any overtime, etc), multiplies each
exemption by $1080, and uses the IRS tax formula ($x + y% for the amount
over $z) to estimate a yearly tax, which is then divided by the number of
pay periods.  This method results in gross overwithholding since no other
deductions one may have are considered, whereas I believe the Pub 15 tables
include the "standard deduction."  

I have found that it is best to estimate your tax bill based on last years
return, adjusted for any known differences, and divide by the number of pay
periods, and use your employer's formula to derive the number of exemptions
based on the tax you want withheld.  You can claim any number of
exemptions, though if you claim over 12 (I think), your employer notifies
the IRS--no problem if you have nothing to hide.
