The year 2020 was certainly, shall we say, "unique" in many ways, and that is also true when it comes to preparing to file your tax return for 2020. If you are using the services of a tax preparer such as Benjamin H. Johnson CPA, there are two pieces of information specific to 2020 that you will need to provide them with.
The first item of concern is the total amount of stimulus money you received from the federal government in 2020 (from both the first and second rounds of economic stimulus payments). The reason you'll want to provide this information is that if, for some reason, you didn't get all the money that you were supposed to, the IRS will give it to you in the form of a tax credit or refund when you file your return.
On the other hand, if you got too much money, no action will be taken. In other words, there is now downside for you of providing this information when you file your tax return.
The second piece of information you'll need to give your tax preparer is whether or not you took an early distribution from a retirement account, which was permitted penalty-free in 2020 due to the pandemic. The financial firm where you have your account should provide you with a 1099-R form if you took such a distribution, which you should give to your tax preparer.
If taking the distribution resulted in taxable income for you, you have the option of spreading that income out over a 3-year period--make sure you let your tax preparer know if you want to exercise that option.
