P30 Monthly Return



Form P30 is a monthly or quarterly return of PAYE, USC, Local Property Tax & PRSI to the Revenue Commissioners.

The P30 is the total of:

  • the tax deducted from the pay (PAYE, USC, LPT) of all employees less any tax refunded to them plus
  • the total PRSI contributions (the amount deducted from pay plus the amount payable by the employer)

and should be remitted to the Collector General within 14 days from the end of the income tax period during which the deductions were made. 

For employers who file their returns and associated tax payments via ROS, time limits are extended to the 23rd of the month immediately following the income tax period during which the deductions were made.

Where a return and associated payment are not made electronically by the new extended deadlines, the extended time limits will be disregarded so that, for example, any interest imposed for late payment will run from the former due dates and not the extended dates.

With each payroll processed Thesaurus Payroll Manager builds the P30. To access this report go to ROS > P30


  • Select P30 by week number OR P30 by date


P30 by week number

The P30 by week number calculates PAYE, USC, Local Property Tax & PRSI liability in line with Revenue's Payroll calendar. With Revenue the first month of every quarter is a five week month - therefore your January, April, July and October P30 return prepared by week number will always be a 5 week month, regardless of the pay date.


P30 by date

The P30 by date, however, calculates PAYE, USC, Local Property Tax & PRSI liability according to your pay dates. Therefore if the first 4 weeks of your payroll, for example, have a January pay date and week 5 a February pay date, only the first 4 weeks of liability will be included in your January P30 prepared by date. 

PLEASE NOTE: Both P30 returns are acceptable and will result in the same overall liability at the end of the tax year. To avoid inconsistencies in payments made to Revenue, however, it is important that users choose a P30 report to use at the start of the tax year and continue to use the same report throughout the year.


P30 reports can be printed, copied/exported or saved as a HTML file.  Alternatively, P30 reports can be emailed directly from the software.  To email reports directly from the software an email address for report emailing is required in File > Amend Company Details.  Please note, it is advisable to enter a password to protect PDF reports.
