PAYROLL emp allowance is enabled in HMRC settings but when you open P32 report all the columns now say 0

Thanks for visiting the Community today, @kscmltd. 

Every year your eligibility will be re-assessed. Thus, you'll need to ensure to re-select Employment Allowance in the product at any point throughout the tax year. However, we recommended that you do this in the first period of the new tax year.

Since it's towards the end of the year, let's check if there are taxes due to HMRC from the payroll that you have run. It may have removed the payables to HMRC after you enable the employee allowance in the settings. 

Here's how: 

1. On the left panel, go to Reports.
2. Scroll down to the Payroll section.
3. Select Employment Payment Record report.

If there are taxes due to HMRC, view submitted FPS and EPS filings in QBO. Otherwise, submit EPS to HMRC in QuickBooks Online Standard payroll. 

For future reference, read through this article: Get your Employer Payment Record (P32). It helps you learn about viewing the employment payment record reports.
