If I work 2 jobs and made less than 10k on the second job. Can I wait until 2020 to file that
Well--then you did not have enough tax withheld. Going forward, change your W-4 with your employer and have them withhold more.
NO, you cannot wait til next year to file that other W-2. ALL of your 2019 income has to be entered on the SAME tax return Form 1040.
Every W-2 that you received must be reported on your tax return, even if they are for small amounts.Remember that each one of those W-2’s has your Social Security number on it, and that income was reported to the IRS by the employer.You do not want to get in trouble with the IRS for under-reporting your income.
ALL of your W-2’s must be entered on the SAME tax return.After you enter the first one, you click Add Another W-2.
