Expenses not entered – financial year closed

I moved to new premises this year and had not yet entered all the receipts as expenses because it has no impact on the vAT declaration.

I cannot now enter these receipts as expenses because the period (2025) is closed, and I can no longer open the quarters because the deadline for the vAT declaration has passed.

Can I simply enter these purchases (from 2025) in the 2026 financial year by updating the fiscal date? Is that fiscally correct?
