Translate this for me

I need to file my tax return in this week.So could anyone translate the following for me?
1)Where can i file my tax return?
2)What documents do I need for filing my tax return?

I guess you mean "kakutei shinkoku," which is due by March 17th this year.

1)Where do I file my tax return?
- Kakutei shinkoku wa doko de suru no desu ka?

2)What documents do I need for filing my tax return?
- Shinkoku ni wa, donna shorui ga hitsuyou desu ka?

By the way, if you go to the tax office of your ward/city, they do have English language explanation brochure available. The tax office do have staff available to help you fill out the form - if you are self-employed, the following documents are needed - take your payment statements (indicating the total amount paid to you and the tax withheld by the payer), expense statements, receipt/record of pension and health insurance contributions paid., etc.

But still I file a tax return every year.But thanks for the translation.It will help me.

Well, if you receive salary from multiple sources, or if you have one main employer but have additional income over a certain amount, you will need to do that each year :) ...I got done with mine a few days ago, I hope you get through with it soon!
