Self Assessment – Pay and File

On the 31 October each year, a self-employed individual/company director, PAYE worker with untaxed non PAYE income will be required to:

  1. File his/her Income Tax Return for the previous calendar year;
  2. Pay the balance of tax for the previous calendar year; and
  3. Pay preliminary Tax payment for the current calendar year.
  4. Submit a tax computation at the time of filing the return.

Payment and Compliance

The self-assessment system applies to individuals with non-PAYE income and to all directors controlling 15% or more of the share capital of a company (even if their entire income is subject to PAYE).

The definition of a “chargeable person” for self assessment purposes includes PAYE taxpayers with non PAYE income where the non PAYE income is not taken into account under the PAYE system.

The ‘Pay & File’ system places an obligation on the individual to file a return, calculate the tax liability, and pay the tax due. Returns for income arising in the year ended 31 December 2018 must be filed on or before 31 October 2019 to avoid a surcharge. The surcharge amounts to 5% of the amount of tax payable for the period subject to a maximum surcharge of €12,695, where the return is filed within two months of the deadline. Otherwise if the return is filed more than 2 months after the deadline, a surcharge of 10% is imposed subject to a maximum of €63,485.

Preliminary tax due for the tax year 2019 must be paid by 31 October 2019 if interest charges of .0219% per day are to be avoided. The tax paid must represent 90% of the individual’s actual liability for 2017 or 100% of the final liability for 2018 (excluding EIIS relief).

Alternatively, for the tax year 2019, a taxpayer can elect to make a preliminary tax payment equal to 105% of the ultimate liability for 2015 (the pre-preceding year), provided a liability arose in that year. This option is only available to taxpayers that pay by direct debit in equal monthly installments. The final installment is payable in December 2019. Where a taxpayer is paying by direct debit for the first time, payment can be made by way of a minimum of three equal installments, and during the following year by way of eight equal installments.

Where the repayment is made due to a Revenue error in applying the legislation, interest will be repaid from the date the tax was paid to the date of repayment otherwise no repayment is due. Refunds of overpayments of preliminary tax carry interest of 0.011% per day .

Tip: The 2018 tax return is due to be filed by 31 October 2019, where your total income for 2019 is less than that in 2018, consider basing your preliminary tax payment on your 2019 estimated liability.

Penalties will apply to any late returns filed late.
