What is ESCT?

ESCT is short for Employer Superannuation Contributions Tax, and is a withholding tax on the superannuation payments an employer makes on behalf of an employee.

ESCT payment 

Ace Payroll automatically deducts the relevant ESCT each pay period. When you pay your Pay As You Earn tax (PAYE), the ESCT is included as part of the PAYE on the IR345 form, but does not appear on the IR348 form.


ESCT rates

The ESCT rate can be entered manually or calculated using the employee’s marginal tax rate. Ace Payroll calculates this for you automatically by estimating the employee’s annual earnings. Letting Ace Payroll calculate the ESCT rate means that if your employee’s annual earnings change, the rate is automatically adjusted.

ESCT on your IRD returns

ESCT amounts are included in the EI return files you submit for payday filing. Payday filing is compulsory from 1 April 2019. More on payday filing...

The following information applies to reporting pays prior to 1 April 2019.

The ESCT shows in box 8 of the IR345, but does not show at all on the IR348. There is no way to show the ESCT on the IR348 Inland Revenue have intentionally designed the forms this way. Because of this, the figures on the IR348 no longer match the figures on the IR345. You must file both forms when you file your monthly return with Inland Revenue.

This makes it vital to
(a) submit your IR345 and your IR348, and
(b) ensure that you use the IR345 total (Box 9) when making your payment to the IRD.  More on the ESCT and monthly returns...
