VAT reclaiming VAT before we registered

Hi there, Kennels9.

You can pull up the VAT 100 report so you'll be able to get the total VAT additional amount under the previous period. Follow the steps below.

1. Go to the Reports menu on the left panel.
2. Scroll down to see the Manage VAT section. Then, click the VAT 100 report.
3. You can also enter the name of the report in the search box.
4. Make sure to set the previous dates and customize it as you want.
5. Click Run report. 

Once done, add the reclaimed VAT in Box 4. Here's how:

1. Go to Taxes and click on Prepare return.
2. Click the Adjust option next to the Box 4 amount.
3. Enter the Adjustment amount.
4. Add a memo about the adjustment.
5. Click Save.

I would also recommend consulting HRMC to verify if you'll need to reclaim VAT on semi-annual or if it's for the first quarterly submission.
