Tax Plan and tax forms

Biden's plan includes the following changes to payroll tax, personal income tax, as well as property and gift taxes:

Imposes a 12.4 percent payroll tax on old age, loss of breadwinner and disability (social security) on income received over $400,000, evenly distributed between employers and employees. This would create a "doughnut hole” in the current Social Security payroll tax, where wages ranging from $137,700, the current salary cap, to $400,000 are tax-free.[1]
Returns the maximum personal income tax rate for taxable income over $400,000 from 37 percent under current law to the level of the Tax Cuts and Jobs Act to 39.6 percent.
Taxes on long-term capital gains and qualified dividends at the usual income tax rate of 39.6 percent on income over $1 million and excludes an increase in the capital gains tax base.[2]
Limits the tax benefit from itemized deductions to 28 percent of the cost for those earning more than $400,000, which means taxpayers earning above this income threshold with tax rates above 28 percent will face limited itemized deductions.
Restores the Pease limit on itemized deductions for taxable income over $400,000.
The deduction from qualified business income (Section 199A) is being phased out for applicants with taxable income above $400,000.
Expands the Earned Income Tax Credit (EITC) for childless workers aged 65 and older; provides individuals with tax benefits related to renewable energy sources.
Increases the Child and Dependent Care Tax Credit (CDCTC) from a maximum of $3,000 for qualified expenses to $8,000 ($16,000 for multiple dependents) and increases the maximum reimbursement rate from 35 percent to 50 percent.
For 2021 and as long as economic conditions require, increases the Child Tax Credit (CTC) from a maximum amount of $2,000 to $3,000 for children 17 years and younger, providing a bonus credit of $600 for children under 6 years. CPC will also be fully reimbursed, which will lead to the abolition of the $2,500 reimbursement threshold and the 15 percent phased-in rate.[3]
Restores the home buyer tax credit that was originally created during the Great Recession to help the housing market. Biden's home buyer loan will provide up to $15,000 for first-time home buyers.[4]
Expands the property and gift tax, restoring the rate and exemption to the level of 2009.

In this way, what tax form will be actual for that time?
