10.2.4 Default interest
In the codes [00617] and [00618] "Delay interest" (in the event that you pay taxes exclusively to the State or to one or more of the regional tax administrations, respectively) on page 14bis of form 200, the amount will be reflected. of the late payment interest corresponding to the amounts that, as a refund for the loss of tax benefits applied in previous tax periods, had been recorded, where appropriate, in the codes [00615] and [00616] and [00633] and [00642].
Furthermore, in those cases in which the loss of tax benefits entails the integration into the tax base of the benefits unduly received, the amount of late payment interest corresponding to the part of the quota derived from said integration will be reflected in these keys.
Calculation of late payment interest
For the calculation of late payment interest, the initial term of the calculation coincides with the date of the day following the end of the voluntary deadline for submitting the declaration of the tax period in which the tax benefits that are restored were applied and the final term coincides with the date of submission of the declaration of the tax period in which the conditions established for the enjoyment of the corresponding tax benefit have been breached.
If as a result of the declaration to which the benefits that are now being restored were applied, a refund was obtained, the initial term of the calculation will coincide with the date on which the refund was received.
To calculate late payment interest, the late payment interest rate in force in each of them is applied to the days that have elapsed each year and included in the late payment period.
The formula to use is the following:
Late interest is equal to C multiplied by Σ Tn x IDn divided by 365 (366 in the case of a leap year) x 100
In which:
C : amount of benefits to be returned.
Tn : number of days of the delay period in each of the years thereof, which are those that elapsed between January 1 or the day following the expiration date of the voluntary deadline for submitting the declaration of the tax period in which the benefits that are restored, if this is later, (or, where applicable, from the date on which the refund was obtained) and the date of presentation of the declaration in which the unduly enjoyed benefits are restored or, failing that, December 31st.
IDn : Default interest in force in each of the years included in the delay period.
The applicable default interest rates are the following:
Note to table :
(1) From 1-1-2009 to 3-31-2009: 7%. From 4-1-2009 to 12-31-2009: 5%. (Back)
In cases of joint taxation, the late payment interest thus calculated in the proportion corresponding to each Administration will be recorded in codes [00617] and [00618], for the loss of tax benefits whose amounts have been recorded in codes [00615. ] and [00616], or in the codes [00633] and [00642], respectively, and, where appropriate, in addition, those that correspond to the part of the quota derived from the integration into the tax base of the benefits unduly received.
