Thank you for reaching out about your first VAT return, Murdac. I understand you're trying to include transactions from before your registration date.

Please note that making manual adjustments can impact your VAT control and Suspense accounts. This happens because the return is tied to a specific period, and any changes to it require corresponding entries to ensure your books remain balanced.

To ensure your VAT return is accurate and fully compliant, we recommend consulting with an accountant or tax professional. They can guide you through the specific process for reclaiming pre-registration VAT, which often involves special rules and regulations.

Check the Make VAT adjustments in QuickBooks to know what happens after an adjustment is made, and how to correct errors in previously filed returns.

If you have other questions, please drop them in the comments, and we'll assist you promptly.
