How large will the payments be?

Most adults will get $1,200, although some would get less. For every qualifying child age 16 or under, the payment will be an additional $500.

How many payments will there be?

just one. Future bills could order up additional payments, though.

How do I know if I will get the full amount?

It depends on your income. Single adults with Social Security numbers who have an adjusted gross income of $75,000 or less will get the full amount. Married couples with no children earning $150,000 or less will receive a total of $2,400. And taxpayers filing as head of household will get the full payment if they earned $112,500 or less.

Above those income figures, the payment decreases until it stops altogether for single people earning $99,000 or married people who have no children and earn $198,000.

According to the Senate Finance Committee, a family with two children will no longer be eligible for any payments if its income surpassed $218,000.

You can’t get a payment if someone claims you as a dependent, even if you’re an adult.

In any given family and in most instances, everyone must have a valid Social Security number in order to be eligible. There is an exception for members of the military.

You can find your adjusted gross income on Line 8b of the 2019 1040 federal tax return.

Do college students get anything?

Not if anyone claims them as a dependent on a tax return. Usually, students under the age of 24 are dependents in the eyes of the taxing authorities if a parent pays for at least half of their expenses.

What year’s income should I be looking at?

2019. If you haven’t prepared a tax return yet, you can use your 2018 return. If you haven’t filed that yet, you can use a 2019 Social Security statement showing your income to see what an employer reported to the I.R.S.

What if my recent income made me ineligible, but I anticipate being eligible because of a loss of income in 2020? Do I get a payment?

The plan does not help people in that circumstance now, but you may benefit once you file your 2020 taxes. That’s because the payment is technically an advance on a tax credit that is available for the entire year. So it will depend on how much you earn.

And there are many other provisions in the legislation. You may be able to file for unemployment or for one of the new loans for small business owners or sole proprietors.

Will I have to apply to receive a payment?

No. If the Internal Revenue Service already has your bank account information from your 2019 or 2018 returns, it will transfer the money to you via direct deposit based on the recent income-tax figures it already has.

What if my direct deposit information has changed or I want to add it for the first time?

On March 30, the I.R.S. said on its website that it would build a portal where people can update their information “in the coming weeks.”

When will the payment arrive?

Treasury Secretary Steven Mnuchin has said he expected most people to get their payments by April 17. Presumably those people using the new portal would not get money until a few weeks after they are first able to provide their information. The I.R.S. has not said when those receiving paper checks would get them.

What if I haven’t filed tax returns recently? Will that affect my ability to receive a payment?

It could. “People who typically do not file a tax return will need to file a simple tax return to receive an economic impact payment,” the I.R.S. announced on its website on March 30. Included among those are many low-income taxpayers, veterans and individuals with disabilities.

The I.R.S. was quick to reassure those people that they would not somehow end up owing tax just because they are filing tax returns now, in order to make it easier to receive this one-time payment. It said it would post information “soon” on its coronavirus information page about how to file a return with “simple, but necessary” information, including direct deposit information.

If you’re worried about money that you already owe that you cannot pay, the I.R.S. recommends consulting a tax professional who can help you request an alternative payment plan or some other resolution.
