# Update a registration

Updates an existing Tax `Registration` object.

A registration cannot be deleted after it has been created. If you wish to end a registration you may do so by setting `expires_at`.

## Returns

A Tax `Registration` object.

## Parameters

- `active_from` (string | timestamp, optional)
  Time at which the registration becomes active. It can be either `now` to indicate the current time, or a timestamp measured in seconds since the Unix epoch.

- `expires_at` (string | timestamp, optional)
  If set, the registration stops being active at this time. If not set, the registration will be active indefinitely. It can be either `now` to indicate the current time, or a timestamp measured in seconds since the Unix epoch.
