Tax Related questions for remote software developer who is giving F1 visa interview : Nepal

Hello folks, I have F1 visa interview scheduled for next week. I basically work as a remote software developer for a us based company. If I am asked about tax related stuff like how I pay tax? How much I pay? what would be the best way to answer?

It seems 1% tax rate has been finalized from 2079-80 budget. I received my salary in Payoneer and then later I withdraw to my bank account. Payoneer does charge 1% for bank withdrawal but I don’t think we can say it as a tax.

If they ask to submit tax documents later, I know I would be in trouble.

Has anyone been in the same situation before? Please help this boy out. Thanks in advance.
