Calculation

The differential rate will be obtained by reducing the rate of the year to be paid or refunded (boxes [00599] and [00600] on page 14 bis of form 200) by the amount of the fractional payments of the tax period subject to declaration made by the reporting entity before each Administration (boxes [00601] to [00606] on page 14 bis of form 200).

For these purposes, the taxpayer who pays taxes exclusively to the State Administration must reflect in box [00611] "Differential rate (State)" on page 14 bis of form 200, with its sign, the result of carrying out the following operation:  

[00611] = [00599] - ([00601] + [00603] + [00605])

In the event that the taxpayer pays taxes to one or more of the Provincial Councils of the Autonomous Community of the Basque Country and/or the Foral Community of Navarre, he/she must reflect in box [00612] "Differential rate Provincial Councils/Navarre (total)" on page 14 bis of form 200, with its sign, the result of carrying out the following operation:

[00612] = [00600] - ([00602] + [00604] + [00606])
