# Migrating from Tax Notification Service to Symmetry Guides
> Plan your TNS-to-Guides migration: feature comparison, transition timeline, Client Support Center access, and Taxes/Filing field mapping.
Symmetry Guides replaces the Tax Notification Service (TNS). This article walks you through what's changing, what to expect during the transition, and where to find your tax data in Symmetry Guides.
## What is Symmetry Guides?
Symmetry Guides is designed to replace TNS and expand on everything it offered. Built on the same trusted tax research database that powers Symmetry's payroll tax products, Guides delivers real-time tax rates, wage bases, and compliance data across 7,000+ U.S. jurisdictions, as well as rate information for Canadian taxes.
Guides also goes beyond TNS capabilities by including step-by-step tax filing information across U.S. jurisdictions, agency-specific contact details, and an AI-powered search feature.

## Frequently asked questions
### Will I lose any of my existing TNS data or tax history?
No. All historical tax rates and wage base data from TNS have been imported into Symmetry Guides. Your rate history is fully preserved and searchable.
### How many tax records can be displayed per page?
TNS had a limit of 1,000 rows returned at a time. With Guides, there are no limits to the number of rows which can be viewed (but there are per page limits; you can view `10`, `25`, or `50` tax records per page).
### Can I export my tax rate data from Symmetry Guides?
Symmetry Guides does not offer a bulk file export of tax rates. Instead, webhooks deliver tax rate changes directly to your systems in real time as they happen. See [Webhooks in Guides: Overview](/guides/webhooks/overview) to set up your first webhook.
### Will I still have access to release notes to view tax changes?
There will be no change to access to the Client Support Center to view tax rate changes in our Symmetry Tax Engine (STE) notes. In a future release of Guides, we will have in-application release notes and release notifications.
### If I already have a tax filing solution, how should I use the step-by-step tax filing information within Guides?
Compare the step-by-step filing information in Guides with your current solution. If something does not fit your workflow, submit a support ticket with specifics so the team can review.
### What if a filing section isn't available for a tax program?
Tabs are always available on each **Tax Program** page. Sections appear when verified agency information is available for that tax program. If a section you need isn't shown, or you have feedback on filing content, submit a support ticket.
