Why does 12Pay calculate a different NI deduction compared with my NI tables?

There are two different methods for calculating NI. Manual tables, or the exact percentage method. 12Pay follows the HMRC recommendation for payroll software and uses the "exact percentage method". You can validate 12Pay's answers at this HMRC web page:

Please note also that directors have NI calculated against annual limits using their cumulative pay.

Why are my tax calculations wrong?

If you don't agree with the results the software is producing, check the following are correct:

  • Tax code
  • Week 1/ month 1 indicator 
  • Pay and tax with previous employers on their P45 
  • Previous taxable pay and tax in this employment
  • Taxable pay this period
  • The current period-end date
  • The type of payroll (weekly/monthly/2 weekly/4 weekly)

If you still don't agree with 12Pay's calculations, check the calculation on the following website:

If after that you still don't understand where the problem lies please contact us with the full details, as outlined in the bulleted list above

How do I pay expenses such as travel or mileage, which aren't taxable or subject to NI?

You can create any number of your own payment or deduction codes for this kind of requirement. The following screenshots show a code being created that can be used to pay mileage @35p/mile.

Important: Once you've added a new payment/deduction code you have to exit the software and restart it before you can use that code on an employee:

Taxable, NI-able, and Pensionable are not ticked, Standard payment and Variable payment are ticked. This allows the payment/deduction code to be applied either on the employee's Pay tab as a regular payment, or on the employee's This Period tab as a one off.

To pay miles at 35p a mile enter the number of miles in the Units box on the employee Payment tab when making a payment, or leave the units blank and just enter a value in the Pay box when making the payment.

In this instance we've also ticked the Hours/Rate/Pay box on the Advanced tab. This means Units and Rate will be shown on the payslips as well as the actual calculated payment.

Why are my NI calculations wrong?

You may have ticked the Directors NI box, or omitted to tick it when it should be ticked. The rules for calculating Directors' NI are different to the rules for calculating regular employees' NI.

Why are the directors on my payroll not paying any NI?

Directors' NI is calculated on total annual salary using annual NI limits. Any NI previously paid is subtracted to arrive at the current NI deduction. Until a director's cumulative pay in the tax year has exceeded the annual NI earnings threshold they will not pay any NI.

For regular employees each pay period is treated in isolation,  meaning they will tend to pay similar amounts of NI each period as long as their earnings remain steady.

Why are so many of my employees getting a tax refund?

If you accidentally skip a pay period, employees may get tax refunds in the following period. Check the employee PAYE tabs to ensure that they have a complete payment history for the current tax year. Having payslips from a past period does not mean you completed that period correctly. For example you may have pressed the Restart Period button which puts the payroll back into its initial state for the period.
