Updated for use at and after Jan 04, 2013
NOTE
The Greux ZZ tables below are the same as for 2012, except that the employEE's Soc Sec withholding rate
has INCREASED to 6.2% (rate= .062) which is back to the old rate that matches the employer's rate. Also the Social Security Wage limit has increased to $ 113,700, and the W/H allowance has increased to $ 3,900. These new rates will be in place as soon as you update your tax tables . You can expect approximately a 2% decrease in net wages, because of the expiration of the 2% decrease in the employee portion of Social Security withholding which was in effect for 2011 and 2012.
Be careful NOT to update your tables until after you have run your last payroll and have backed up
your PR data that will be used for 2012 W-2s.
The tables below DO NOT reflect an additional .9% employee Medicare withholding for individual wages over $200,000. The employer does NOT match that amount. This could be accomplished by defining a new deduction if needed. The new requirement will be accomodated in future updates within a few months.
If you have not done so since the above date, you should Download/Install Updates for
your Greux programs (File | Utilities | Download Updates). Then for every company that has a Payroll, get
to the P/R Configuration/Tax tables window (shown below). Select US and click on the
"Update selected tax table" button. If you need tables for your State, then
select your state and click "Update...". If your state is not there, contact
KISS Development. This is all you need to do to get the
latest tables.
These Tax Table Masters are always available with the Payroll module.
The following is furnished for reference only for GREUX users. You may use the
Tax Tables listed below to verify that you have updated your tables.
Reference: Circular E for January 2013, see Listed below are the withhholding tables effective
January 2013.
If you
have run several payrolls using the old US single and married tables, that's OK.
If the tax rates for your state have changed, let us know. We do not
monitor all state withholdings rates. That is your responsibility as an
employer. However if yours did change and we don't have the new rate,
we will ask you to send us a copy of the state's
computer formula (annualized). We will update the calculations and include in the master tables used above.
For Greux users this service is free, unless you require telephone assistance.
