There are two possible methods of calculating Director's NIC:
Pro-Rata Basis (Alternate Basis)
HMRC guidelines advise that the Annual Basis is the preferred method for calculating Directors' NIC - that is:
Under the Pro-Rata Basis (Alternate Basis), on the final payment in month 12, the entire NIC's are to be recalculated on total earnings in month 12 and a manual adjustment made in that remittance. HMRC guidelines state that this method can lead to disproportionate amounts of NIC being payable at year end.
BrightPay facilitates both of these calculation methods. The user desired method of calculating NI must be indicated at the first pay period for the Director and cannot be changed thereafter.
The Annual Basis assigns the NI thresholds of LEL, PT, ST and UEL on an annual/cumulative basis.
This means that in week one, the thresholds assigned to the calculation of the NI for that week will be:
The annual thresholds are assigned in total and the NI is calculated on a constant cumulative basis.
This method differs to the normal calculation of NI for a non-director employee which, in week one, would only assign the weekly thresholds of:
This method differs to the Annual Basis in that it assigns the periodic LEL, PT, ST and UEL to each periodic wage/ salary in the same manner as the NI calculation for a non-Director employee. Therefore on a weekly basis, the following NI thresholds are assigned:
This alternative method is only recommended when a Director's periodic salary will consistently exceed the equivalent periodic UEL in each pay period AND ONLY where the Director will be paid for the entire tax year as a Director.
Due to the different application of the NI thresholds under both Director NI calculations, it is not possible to switch between the two calculation methods during the tax year.

Applying the Pro-Rata Basis in BrightPay
By default, BrightPay will automatically apply the Annual Basis for NIC calculation for Directors, as this is the preferred method of calculation by HMRC. The pro-rata version is only recommended when a Director's periodic salary will consistently exceed the equivalent periodic UEL in each pay period AND ONLY where the Director will be paid for the entire tax year as a Director.
