How to file a tax return

Match each income form to the return for that same year, type the printed amounts, and file only after the refund or the amount due makes sense.

The answer

Collect every income form for that year, enter the printed amounts on the matching lines, and submit through the tax agency for that year.

One year, one pile of forms

A tax return covers one year. Put that year’s forms in one pile: wages, interest, contract or freelance income, and any other form a payer mailed or posted. The year printed on the form has to be the year of the return. A form from the year before belongs to that earlier return, not to this pile.

Open the return from the tax agency, or from software that submits to that agency. Use the instructions for the same year. Lines move. A blog that says “put wages on line 1” may be describing a different year than the form in your hand. When they disagree, the form’s own instructions win.

Practical steps

  1. Step 01

    Sort the forms by the year on the front. Set aside anything from another year so it cannot be typed into this return.

  2. Step 02

    If a payer told you a form is coming and it is not in the pile, ask that payer for a copy. Do not type a number you remember from a deposit.

  3. Step 03

    Enter each box from the form into the line the instructions name. Wages from a job, interest from a bank, and contract income are different lines. Do not add them together first.

  4. Step 04

    Look at the refund or the amount due before you submit. If you had tax withheld and the return says you owe a large extra amount, find the line that changed before you file. A missing form is a common reason.

  5. Step 05

    Submit through the agency’s file option or the software’s submit button. Save the confirmation and a copy of the return. The copy is what you compare if a late form arrives.

Examples

  • A job and a savings account

    The pile has a wage form showing 42,000 in wages and 3,200 in tax withheld, plus an interest form showing 40 in interest. Those are two entries, not 42,040 in wages. The return’s wage line gets 42,000. The interest line gets 40. The withheld amount is what you already paid in, and it is why a refund can exist. This is an illustration of where the numbers go, not a promise of what you will owe.

Common mistakes

  • Typing a bank deposit instead of the amount printed on the form.
  • Using last year’s line numbers on this year’s form.
  • Filing before a known form has arrived, then guessing the missing amount.

Questions

What if a form arrives after you filed?

Keep it. The instructions for that year say whether you amend. Sending a second guess on the same line, from memory, is not an amendment. Compare the new form with the copy of the return you saved.

Can this page tell you whether you get a refund?

No. A refund or a bill depends on the forms, the withholding, and the lines that year’s return asks. This page is the order of work. The form computes the result.
