You can add wage income that either you or your spouse earns to help Hurdlr project the correct tax bracket for your income level, giving you a more accurate tax calculation.
However, Hurdlr's Tax Engine doesn't estimate any taxes owed on your wage income, since those are already withheld.
To add your annual wage income for yourself:
On the mobile app go to the Taxes tab and tap the gear icon in the top right corner or on the web app tap the gear icon in the top right corner and select Tax Profile
In Annual Wage Income Income setting enter the total amount of pre-tax W-2 earnings for the entire year
If you are married, after selecting your Marital Status, you’ll see the option to add your Annual Spousal Income.
