On my tax return: “can someone claim me as a dependent?” I selected no because I thought they can’t claim 18 and older. But apparently they can. Will that affect anything and will I hav

Your question cut off in mid-sentence.  Did you already e-file a 2020 return?

 If you can still be claimed as a dependent on your parents' tax return and you do not say so on your own return you will mess up their return big time.  So you need to understand what you are doing.

There are two kinds of dependents---qualifying child and qualifying relative.   If you meet the criteria to be claimed as either kind you must say on your own tax return that you can be claimed.  (and that means no stimulus for you).

For tax year 2020 do you meet the criteria to be someone else's qualifying child or qualifying relative?

WHO CAN I CLAIM AS A DEPENDENT?

You can claim a child, relative, friend, fiance (etc.) as a dependent on your 2019 taxes as long as they meet the following requirements:

Qualifying child

• They are related to you.

• They cannot be claimed as a dependent by someone else.

• They are a U.S. citizen, resident alien, national, or a Canadian or   Mexican resident.

• They are not filing a joint return with their spouse.

• They are under the age of 19 (or 24 for full-time students).

• No age limit for permanently and totally disabled children

  •      They live with you for more than half the year (exceptions apply).

Qualifying relative

• They don't have to be related to you (despite the name).

• They cannot be claimed as a dependent by someone else.

• They are a U.S. citizen, resident alien, national, or a Canadian or Mexican resident.

• They are not filing a joint return with their spouse.

• They lived with you the entire year.

• They made less than $4300  (not counting Social Security)

• You provided more than half of their financial support. More info

When you add someone as a dependent, we'll ask a series of questions to make sure you can claim them.

If you can be claimed as a dependent and you answer the question in My Info incorrectly, here is what happens if you e-file first:  Your Social Security number goes into the IRS system as having been used.  When your parents try to e-file, their e-file is rejected and they will find it impossible to e-file their own tax return.  Then they will have to print, sign and mail their return and wait for months for it to be processed.  You, meanwhile, will have to file an amended tax return on a special form called a 1040X, which also takes months for the IRS to process.  So make sure you know the correct answer to "Can anyone claim you as a dependent on their tax return?"

Did you click that big orange button that said “Transmit my return now?”  If you did that, you cannot do anything to fix it yet.  The IRS will begin to accept/reject 2020 returns on January 27.  You have to wait for the email that tells you if your return was accepted or rejected.  If you do not see an email, check your spam folder.

You cannot change or add anything on the return that you just e-filed, nor can you stop it.  It is too late, just like when you put an envelope in a US mailbox on the corner.

If you left out a W-2, or a dependent, or a 1099 etc…DO NOT change your return while it is “pending.”  The changes will go nowhere.

Now you have to wait until the IRS either rejects or accepts your return.  If your return is rejected, you will be able to go into your account and make the necessary changes to your tax return and re-submit your return.

 If the IRS accepts your return, however, then you have to wait longer until it has been fully processed and you have received your refund.  THEN you can prepare an amended tax return and mail it in. You have to be able to work from that return exactly the way it was when it was e-filed originally.  You will need to use a form called a 1040X. return.  

 Meanwhile, DO NOT go in and start changing anything on your return in the system, or you will make a mess for yourself.  Sit tight and wait until you see what the IRS does with the return you just e-filed
