When will quickbooks show the new tax relief of 0.55p per mile

While QuickBooks eventually adheres to official tax updates, we don't have a specific release date for this new rate's rollout just yet. In the meantime, you can manually update your mileage rate by editing the mileage reimbursement item under Products and Services to ensure your tax relief calculations are accurate.
