Payroll Construction Services assists in processing weekly or biweekly payroll, payroll tax returns, job costing, certified payroll and prevailing wage reporting and QuickBooks implementation or integration. The interest is on construction to ensure that any estimates are similar to the actual pay stubs and reports.

Most checks include
- Federal income tax per your W-4
- Medicare and Social Security.
- NJ-W4 state income tax new Jersey.
- Employee contribution of New Jersey TDI and FLI.

What is the percentage that New Jersey takes?
There is no percentage of it. New Jersey has progressive state income tax tables and a rate of NJ-W4 of the employee. TDI and FLI are also contributed by the employees. On top of that is Federal Social Security and Medicare. Status, benefits, union, or fringe lines difference may lead to the fact that two workers, having the same gross, may have different nets.
New Jersey Local or city income tax
People do not have to pay local income tax in New Jersey. Due to certain municipalities, some companies are subjected to an employer payroll tax, a company expense. It does not decrease take-home pay of employees.
NJ-W4 right-sizing withholding
Form NJ-W4 is used to determine your rate, as well as to add money by the paycheck in case of a cushion. Change your tax posture with the update of big overtime runs, bonus, change of pay frequency or any life change. The form is provided by employers and not paid out at the preferred rate by the employee.
Pennsylvania workers in New Jersey may submit the state reciprocity certificate to prevent the withholding of New Jersey. A refund request can be made by New Jersey tax in case of error in taxing a nonresident return.
New Jersey Bonuses and commissions
The state of New Jersey does not apply special flat state rate on bonuses. In case a bonus is added to ordinary wages the employer adds and reports the standard tables. In case it is paid in a separate and distinct check that is still used by the employer, state tables are still used in employing the method of separate supplemental wages. At the federal level a different and distinct bonus can be deducted in a flat rate. This is the reason why the same gross bonus can be indicated by two calculators as having different nets.

- Most wage payments fall under Social Security and Medicare.
- Wage basis to New Jersey workers on the TDI and FLI and renew at the beginning of the year.
