Income Tax Changes in 2019 and 2020

Last updated 29th Nov 2022

In this article, we'll continue the approach taken in the past, explaining the significant income tax changes in 2020. That discussion will include changes to Social Security and Medicare, federal income tax standard deductions and exemptions, mileage deduction rates, earned income credits, Hope and Lifetime Learning tax credits, in addition to changes to retirement accounts such as the 401(k), 403(b), IRAs, and Roth plans.

Federal Income Tax Filing Deadline

The filing deadline for the year 2019 is Wednesday April 15, 2020. Information appearing in this article applies to changes effective in 2020, which then become part of a taxpayer's return in 2021.

Income Tax Rates

Back in 2018, the Tax Cuts and Jobs Act introduced the most significant income tax changes in decades. Taxable incomes above the following thresholds in 2020 now fall into the 37% bracket (the highest under the 2018 tax bill): Married Filing Separately ($311,025), Unmarried Individuals ($518,400), Head of Household ($518,400), and Married Filing Joint Returns ($622,050).

Capital Gains Tax

ATRA also made several important changes to the treatment of long-term capital gains, and these were modified slightly by the Tax Cuts and Jobs Act:

Unmarried individuals (Single) with income over $200,000 and married couples filing jointly with income over $250,000 will also pay a 3.8% Medicare surcharge tax on investment income; thereby increasing the effective rate on capital gains to 23.8% (20% + 3.8%).

Social Security and Medicare

As was the case in the past, all wages earned in a given year are taxed at the 1.45% rate for Medicare. In 2020, wages paid in excess of $200,000 for unmarried filers and in excess of $250,000 for married filers will be subject to an extra 0.9% tax.

Social Security tax remains at 6.20%, while the wage limit, or Social Security maximum, increases to $137,700. The Cost of Living Adjustment (COLA) was 1.6% in 2020, increasing the SSI limit to $3,011 per month.

Unified Credits, Gift Tax and Estate Tax

ATRA also increased the estate and gift tax rate from 35 to 40%. The gift tax and estate tax exclusion continue to be indexed for inflation and increases to $15,000 (the same as 2019) and the Unified Credit increases to $11.58 million in 2020.

Standard Deductions

According to the IRS, approximately two out of every three taxpayers claim the standard deduction on their income tax returns. In 2020, this value increased slightly over the prior year for most taxpayers, including:

  • Single (Unmarried Individuals): $12,400 (an increase of $200)
  • Married Filing Separately: $12,400 (an increase of $200)
  • Head of Household: $18,650 (an increase of $300)
  • Married Taxpayers Filing Jointly and Qualifying Widow(er)s: $24,500 (an increase of $400)

Exemption Values

The amount deducted for each exemption claimed on a federal income tax return was eliminated in 2018 by the Tax Cuts and Jobs Act.

Mileage Deduction Rates

Studies funded by the IRS continue to reflect the price of gasoline. The standard mileage deductions (or reimbursement rates) appear in the following table:

CategoryRate (January to December)Business Miles57.5 cents per mileCharitable Services14.0 cents per mileMedical Travel17.0 cents per mile

Increase to Earned Income Credit

The earned income credit applies to working taxpayers that have income falling below certain thresholds. The qualification threshold depends on the number of persons in each family. The thresholds in 2020 to qualify for this credit include:

  • No Children: earnings must be less than $15,820, or $21,710 if Married Filing Jointly.
  • One Child: earnings must be less than $41,756, or $47,646 if Married Filing Jointly.
  • Two Children: earnings must be less than $47,440, or $53,330 if Married Filing Jointly.
  • Three or More Children: earnings must be less than $50,954, or $56,844 if Married Filing Jointly.

The tax credits themselves also increased in 2020, with the maximum received as indicated below:

  • No Children: $538
  • One Child: $3,584
  • Two Children: $5,920
  • Three or More Children: $6,660

Coverdell ESA, Lifetime Learning and Hope Scholarship Credits

ATRA also eliminated the sunset provision for Coverdell Education Savings Accounts. Taxpayers with modified adjusted gross income less than $110,000 ($220,000 if filing a joint return), may be eligible to contribute to a Coverdell ESA. There are no limits on the number of separate Coverdell accounts that can be established for a beneficiary, but the total of all contributions to a single beneficiary cannot exceed $2,000 each tax year.

The maximum Lifetime Learning Credit is $2,000 in 2020. The credit applies to 20% of the first $10,000 of a taxpayer's out-of-pocket expenses for all students attending an institution of higher education. A taxpayer cannot claim the Hope Credit and the Lifetime Learning Credit in the same tax year for the same student.

In 2020, the taxpayer's modified adjusted gross income is used to determine the reduction in the amount of the Lifetime Learning Credits. The income threshold for the Lifetime Learning Credit increases to $59,000 or $118,000 for those filing joint returns in 2021.

Contributions to Retirement Accounts

The contribution limits for 401(k) as well as 403(b) plans increases to $19,500 in 2020, while catch up contributions increase to $6,500. The contribution limit for SIMPLE retirement plans increases to $13,500, while the catch up contribution limit is $3,000.

In 2020, the contribution limits for Traditional IRAs and Roth IRAs is $6,000, with a catch-up contribution of $1,000 for anyone age 50 or older by the end of the calendar year. The income limits for individuals willing to fund Traditional IRAs as well as Roth IRA plans increased modestly again in 2020. The income phase-out threshold for Roth IRAs now starts at $196,000 for those filing joint returns, which is an increase of $3,000. The phase-out threshold for taxpayers filing their returns as Head of Household or Single is now $124,000, which is a $2,000 increase over last year's value.

The income phase-out limits that apply to Traditional IRAs remain the same for those individuals covered by a retirement plan at work. The 2020 income phase-out limits start at $104,000 for joint filers (an increase of $1,000 from 2019), and $65,000 for those with a filing status of Single or Head of Household (a $1,000 increase from 2019).
