Google Tasks is one of the most underrated productivity tools inside Google Workspace. It’s free, works across every device, and connects directly to Gmail and Google Calendar. But many users hit the same wall: they add tasks with due dates, expect notifications to follow, and then nothing happens.
Google Tasks notifications can feel unpredictable if you don’t know how they actually work. This guide covers exactly how to set up Google Tasks notifications on Android, iPhone, and desktop, and walks through the most effective fixes when alerts stop working.
How Google Tasks Notifications Work
Google Tasks does not send standalone app notifications the same way a dedicated to-do app like Todoist does. Understanding this distinction saves a lot of frustration.
When you add a date and time to a Google Task, that task appears on your Google Calendar. The notification you receive comes from Google Calendar, not Google Tasks directly. This means:
- If you only set a due date (no specific time), you may not get a push alert.
- If you set both a date and a time, Google Calendar fires a notification at the scheduled moment.
- If Google Calendar notifications are disabled on your device, you will not receive Google Tasks alerts.
Mobile Push Notifications
On Android and iOS, Google Tasks can send push notifications through the Google Tasks app or via the Google Calendar app when a task has a date and time. The app-level notification must be enabled in your phone’s settings, and your task must have a time component to trigger an alert.
Google Calendar Notifications for Tasks
Google Calendar tasks notifications are the most reliable way to stay on top of due tasks. When a task with a time appears in Google Calendar, it behaves like any other calendar event: you can get a notification 10 minutes, 30 minutes, or any interval before the due time.
To see your Google Tasks inside Calendar, open Google Calendar on any device and look for the Tasks calendar in the left sidebar. Make sure it is toggled on (checked). Tasks with times show as small cards on the calendar grid.

How to Enable Google Tasks Notifications on Android
Android handles Google Tasks notifications through the Google Calendar or Google Tasks app depending on how your device is configured.
Using the Google Tasks app:
- Open Google Tasks on your Android device.
- Create a task and tap Add details (the pencil icon).
- Tap Add date/time and set a specific date and time (not just a date).
- Save the task. Google Calendar will display this task and fire a notification at the set time.
Check Android app notification settings:
- Go to Settings on your Android device.
- Tap Apps, then find Google Tasks (or Google Calendar).
- Tap Notifications and make sure notifications are set to Allow.
- Check that Do Not Disturb mode is off or has an exception for Google Calendar.
Enable battery optimization exception:
Android aggressively kills background apps to save battery, which can prevent notifications from firing. To fix this:
- Go to Settings > Apps > Google Tasks (or Google Calendar).
- Tap Battery.
- Select Unrestricted or Don’t optimize.
Repeat this for Google Calendar as well, since tasks notifications route through Calendar on many devices.
How to Enable Google Tasks Notifications on iPhone
iPhone users often find Google Tasks notifications not working because of iOS notification permission settings.
Enable Google Tasks notifications on iPhone:
- Go to Settings on your iPhone.
- Scroll down to Google Tasks and tap it.
- Tap Notifications.
- Toggle Allow Notifications on.
- Choose your preferred alert style (Banner, Lock Screen, Notification Center).
Enable Google Calendar notifications for tasks on iPhone:
Since Google Tasks routes due-time alerts through Google Calendar:
- Go to Settings > Google Calendar on your iPhone.
- Tap Notifications and enable alerts.
- Open the Google Calendar app, go to Settings (your profile picture > Settings).
- Tap your account, then Events, reminders, and tasks.
- Make sure Notify on this device is enabled.
Check Focus modes:
If you have a Focus mode or Do Not Disturb active, notifications from Google Tasks and Calendar may be silenced. Go to Settings > Focus and either disable it or add Google Calendar to the allowed apps list.
How to Enable Google Tasks Notifications on Desktop
Desktop notifications for Google Tasks come from Google Calendar in the browser or from Chrome’s notification system.
Enable Google Calendar notifications in Chrome:
- Open calendar.google.com in Chrome.
- Click the gear icon (top right) and go to Settings.
- In the left sidebar, click Tasks under “Other calendars.”
- Scroll to Event notifications and click Add notification.
- Set the timing (e.g., 10 minutes before).
- Save your settings.
Allow Chrome desktop notifications:
- In Chrome, click the lock icon in the address bar on calendar.google.com.
- Set Notifications to Allow.
- Make sure your operating system (Windows or macOS) allows Chrome to send notifications. On Windows: Settings > Notifications & actions > Chrome should be on. On macOS: System Settings > Notifications > Google Chrome should be enabled.
Fix Google Tasks Notifications Not Working
If you have followed the setup steps and Google Tasks notifications are still not working, these targeted fixes address the most common causes.
Android: Fix Notifications Not Firing
Clear the Google Calendar app cache:
- Go to Settings > Apps > Google Calendar.
- Tap Storage and cache.
- Tap Clear cache (not Clear data, which removes your settings).
- Restart your phone.
Re-add your Google account:
Sometimes account sync issues block notifications. Go to Settings > Accounts, remove your Google account, then re-add it. This forces a fresh sync.
Check sync settings:
- Go to Settings > Accounts > Google.
- Make sure Auto-sync is enabled and Calendar sync is turned on.
iPhone: Fix Notifications Not Working
Force-quit and reopen the app:
Swipe up to force-quit Google Tasks and Google Calendar, then reopen both. A fresh launch often re-establishes the notification connection.
Sign out and sign back in:
- Open the Google Tasks app.
- Tap your profile picture.
- Tap Manage accounts on this device and remove your account.
- Re-add your Google account.
Update the app:
Open the App Store, search for Google Tasks and Google Calendar, and tap Update if updates are available. Bugs in older versions can break notifications.
Desktop: Notifications Not Showing
Check browser notification permissions:
Go to Chrome Settings > Privacy and security > Site settings > Notifications. Find calendar.google.com and make sure it is set to Allow. If it was previously blocked, delete the blocked entry and refresh the page to trigger the permission dialog again.
Use Google Calendar reminders instead of task notifications:
For reliable desktop alerts, add a reminder directly to the task within Google Calendar. Open the task on calendar.google.com, click on the task, then add a notification time. Calendar reminders have a more reliable delivery mechanism than the default task alert.
Why Are Google Tasks Notifications Late?
Late notifications are a common issue, especially on Android. The main causes:
- Battery optimization: Android delays notifications from background apps. Set Google Calendar to unrestricted battery use as described above.
- Doze mode: On Android 6 and later, Doze mode delays background activity. Keep your phone plugged in or unlocked near the notification time to bypass this.
- Time zone mismatch: If your Google account and phone are in different time zones, tasks can fire at the wrong local time. Go to Google Calendar Settings > Time zone and make sure it matches your device’s time zone.
- Notification sync delay: Occasionally Google’s servers delay notification delivery. This is rare and usually resolves within a few minutes.
TasksBoard gives Google Tasks a full-screen kanban board view, team sharing, and better task visibility, all without leaving your Google Workspace account.

Get Better Task Visibility with TasksBoard
Google Tasks has a known limitation when it comes to due dates and reminders: the interface buries upcoming tasks in a flat list. If you have dozens of tasks spread across multiple lists, it is easy to miss a due date even when notifications are working correctly.
TasksBoard is a Google Workspace add-on that gives Google Tasks a proper kanban board interface. You can see all your task lists side-by-side as columns, drag cards between columns, and view everything that is due today in one glance.
For teams, TasksBoard adds shared task lists so colleagues can see and contribute to the same Google Tasks project. Read our full breakdown of Google Tasks for Teams to see how sharing works.
If you want a visual overview of how TasksBoard compares to using Google Tasks on its own, our TasksBoard Review covers pricing, features, and ideal use cases in detail.
Google Tasks Notification Best Practices
Once your notifications are working, a few habits keep them useful rather than noisy.
- Always set a time, not just a date: Tasks with only a date do not reliably trigger push alerts. Add a specific time to every task that needs an alert.
- Use meaningful due times: Set notifications for when you are actually available to act on the task, not at midnight or during a meeting block.
- Limit work-in-progress: If every task has a notification, they lose meaning. Use notifications for true deadlines, not every item on your list.
- Pair tasks with Google Calendar events: For larger tasks that take time blocks, create a matching Calendar event. This gives you both the task reminder and the event notification.
- Review the Scheduled view weekly: In Google Tasks, switch to the Scheduled view to see all upcoming due-dated tasks. This serves as a backup review in case a notification was missed.

Frequently Asked Questions
Conclusion
Google Tasks notifications work reliably once you understand that they are powered by Google Calendar rather than by the Tasks app itself. The essential step is setting a time, not just a date, on every task that requires an alert. From there, ensure the Google Calendar and Google Tasks apps have notification permissions on your device, disable battery optimization on Android, and check Focus or Do Not Disturb modes on iPhone.
If Google Tasks notifications are still not working after the fixes above, clearing the Google Calendar app cache and re-syncing your account resolves most remaining issues. For desktop users, granting Chrome notification permissions and adding a default task notification in Google Calendar Settings completes the setup.
If you want better visibility into upcoming tasks beyond what notifications alone provide, TasksBoard gives Google Tasks a full-screen board view so you always see what is due, not just when your phone buzzes.
