2019-2020 Tax Calculator
Calculate your federal income tax for tax years 2019 and 2020 with our accurate, up-to-date calculator.
Comprehensive 2019-2020 Tax Calculator Guide
Module A: Introduction & Importance of the 2019-2020 Tax Calculator
The 2019-2020 tax years represent a critical period in U.S. tax history, marking the full implementation of the Tax Cuts and Jobs Act (TCJA) of 2017. This legislation introduced sweeping changes to the federal tax code that significantly impacted individuals and businesses alike. Our 2019-2020 tax calculator incorporates all these changes to provide you with the most accurate tax liability estimation available.
Understanding your tax obligations for these years is particularly important because:
- Historical tax rates: The 2019-2020 period features unique tax brackets that differ from both pre-TCJA years and subsequent legislation
- Deduction changes: Standard deductions were nearly doubled while many itemized deductions were limited or eliminated
- Credit modifications: Several tax credits were expanded or modified, including the Child Tax Credit and Earned Income Tax Credit
- Retroactive planning: Many taxpayers need to file amended returns for these years to claim missed credits or correct errors
According to the IRS, over 150 million individual tax returns were filed for each of these years, with the average refund being approximately $2,869 in 2019 and $2,549 in 2020. Our calculator helps you understand where your situation fits within these national statistics.

Module C: Formula & Methodology Behind the Calculator
Our 2019-2020 tax calculator uses the exact tax tables and rules published by the IRS for these tax years. Here’s a detailed breakdown of the calculation methodology:
1. Tax Bracket Structure
The calculator applies the progressive tax system where different portions of your income are taxed at different rates. The 2019 and 2020 tax brackets were as follows:
| Filing Status | 2019 Tax Brackets | 2020 Tax Brackets |
|---|---|---|
| Single |
10%: $0-$9,700 12%: $9,701-$39,475 22%: $39,476-$84,200 24%: $84,201-$160,725 32%: $160,726-$204,100 35%: $204,101-$510,300 37%: Over $510,300 |
10%: $0-$9,875 12%: $9,876-$40,125 22%: $40,126-$85,525 24%: $85,526-$163,300 32%: $163,301-$207,350 35%: $207,351-$518,400 37%: Over $518,400 |
| Married Filing Jointly |
10%: $0-$19,400 12%: $19,401-$78,950 22%: $78,951-$168,400 24%: $168,401-$321,450 32%: $321,451-$408,200 35%: $408,201-$612,350 37%: Over $612,350 |
10%: $0-$19,750 12%: $19,751-$80,250 22%: $80,251-$171,050 24%: $171,051-$326,600 32%: $326,601-$414,700 35%: $414,701-$622,050 37%: Over $622,050 |
2. Calculation Process
The calculator performs these steps in sequence:
- Determine Taxable Income:
- Starts with your entered income amount
- Subtracts either the standard deduction (based on filing status) or your itemized deductions if entered
- Result is your taxable income (cannot be less than $0)
- Apply Tax Brackets:
- Your taxable income is divided into the appropriate brackets
- Each portion is taxed at its corresponding rate
- For example, if you’re single with $50,000 taxable income in 2020:
- $9,875 taxed at 10% = $987.50
- $30,250 ($40,125 – $9,876) taxed at 12% = $3,630
- $9,875 ($50,000 – $40,126) taxed at 22% = $2,172.50
- Total tax before credits = $6,790
- Subtract Tax Credits:
- Credits are subtracted directly from your tax liability (unlike deductions which reduce taxable income)
- Common credits include:
- Child Tax Credit (up to $2,000 per child in 2019-2020)
- Earned Income Tax Credit (up to $6,557 in 2019, $6,660 in 2020)
- Education credits (American Opportunity and Lifetime Learning)
- Saver’s Credit for retirement contributions
- Calculate Final Figures:
- Final tax liability = Tax from brackets – Tax credits + Extra withholding
- Effective tax rate = (Final tax liability / Total income) × 100
- After-tax income = Total income – Final tax liability
3. Special Considerations
Our calculator also accounts for these important factors:
- 2020 COVID-19 Provisions: The CARES Act allowed for:
- Up to $300 above-the-line charitable deductions for non-itemizers
- Suspension of required minimum distributions from retirement accounts
- Special rules for coronavirus-related retirement distributions
- Alternative Minimum Tax (AMT): While not calculated in this tool, we provide warnings when your income might trigger AMT considerations
- Capital Gains: Long-term capital gains use different tax rates (0%, 15%, or 20%) based on your income
- Self-Employment Tax: 15.3% tax on net earnings for self-employed individuals (not included in this calculator)
Module D: Real-World Examples & Case Studies
To help you understand how the calculator works in practice, here are three detailed case studies covering common tax situations for 2019-2020:
Case Study 1: Single Professional with Standard Deduction
Scenario: Emma is a single marketing manager earning $75,000 in 2020. She takes the standard deduction and has $1,500 in tax credits from her IRA contributions.
| Gross Income: | $75,000 |
| Standard Deduction (Single): | $12,400 |
| Taxable Income: | $62,600 |
| Tax Calculation: |
10% on first $9,875 = $987.50 12% on next $30,250 = $3,630 22% on remaining $22,475 = $4,944.50 Total Tax Before Credits: $9,562 |
| Tax Credits: | -$1,500 |
| Final Tax Liability: | $8,062 |

How does the standard deduction compare to itemizing deductions?
The choice between taking the standard deduction or itemizing depends on which gives you the larger deduction. Here’s how to decide:
- Standard Deduction:
- Fixed amount based on filing status ($12,400 single, $24,800 joint in 2020)
- No need to track expenses or provide documentation
- Best for taxpayers with relatively simple financial situations
- Itemized Deductions:
- Common deductions include:
- State and local taxes (capped at $10,000)
- Mortgage interest
- Charitable contributions
- Medical expenses (over 7.5% of AGI in 2019-2020)
- Requires detailed records and receipts
- Only beneficial if total exceeds standard deduction
- Common deductions include:
Our calculator allows you to enter either the standard deduction or your itemized total to compare which is better for your situation.
What tax credits am I likely to qualify for in 2019-2020?
The most common tax credits for 2019-2020 include:
- Child Tax Credit: Up to $2,000 per qualifying child under 17. Phase-out begins at $200,000 ($400,000 joint).
- Earned Income Tax Credit: For low- to moderate-income workers. Maximum credit ranges from $529 (no children) to $6,660 (3+ children in 2020).
- American Opportunity Credit: Up to $2,500 per student for first four years of college. 40% may be refundable.

- Saver’s Credit: 10-50% of retirement contributions up to $2,000 ($4,000 joint) for low- and moderate-income taxpayers.
- Child and Dependent Care Credit: 20-35% of up to $3,000 in expenses for one child ($6,000 for two+).
- Adoption Credit: Up to $14,080 (2019) or $14,300 (2020) per eligible child.
Our calculator includes a field for total tax credits – be sure to add up all credits you qualify for to get the most accurate result.
How does the calculator handle self-employment income?
Our calculator treats self-employment income as follows:
- You should enter your net self-employment income (gross income minus business expenses)
- The calculator applies the standard or itemized deductions to this net income
- For self-employment tax (15.3%), you would need to calculate this separately as it’s not included in this federal income tax calculator
- If you qualify for the 20% qualified business income deduction (Section 199A), you can enter this as a negative adjustment to your income
Example: If you have $100,000 in self-employment income and $20,000 in expenses:
- Net income = $80,000
- QBI deduction (20%) = $16,000
- Adjusted income for calculator = $64,000
Remember that you’ll also owe self-employment tax (15.3%) on 92.35% of your net earnings, in addition to the income tax calculated here.
What should I do if I think I made a mistake on my 2019 or 2020 return?
If you discover an error on your already-filed 2019 or 2020 return, follow these steps:
- Determine the type of error:
- Math errors (IRS usually corrects these)
- Missing forms or schedules
- Incorrect filing status
- Underreported income
- Missed deductions or credits
- For math errors or missing forms:
- The IRS will typically send you a notice and correct it
- You usually don’t need to file an amended return for these
- For other errors:
- File Form 1040-X (Amended U.S. Individual Income Tax Return)
- You have 3 years from the original filing date to claim a refund
- If you owe additional tax, file as soon as possible to minimize penalties
- If you underreported income:
- File an amended return immediately
- The IRS may assess penalties and interest
- Consider using the IRS Voluntary Disclosure Program if the error was significant
Our calculator can help you determine what your correct tax liability should have been, which you can then use to complete Form 1040-X.
How does the calculator account for state taxes?
Our calculator focuses exclusively on federal income tax calculations. Here’s what you need to know about state taxes:
- State income tax rates vary from 0% (no income tax states) to over 13% (California)
- Some states use federal taxable income as their starting point
- Others have their own calculation methods
- State and local taxes (SALT) are deductible on your federal return, but capped at $10,000
To estimate your total tax burden:
- Use our calculator for federal taxes
- Check your state’s department of revenue website for state tax calculators
- Add both amounts together for your total income tax liability
- Remember to also account for FICA taxes (7.65% for employees, 15.3% for self-employed)
Can I still file my 2019 or 2020 taxes if I haven’t yet?
Yes, you can still file taxes for 2019 and 2020, but there are important considerations:
- 2019 Taxes:
- Original due date: April 15, 2020
- If you’re due a refund, you have until April 15, 2023 to file and claim it
- If you owe taxes, file as soon as possible to stop penalty accumulation
- 2020 Taxes:
- Original due date: April 15, 2021 (extended to May 17, 2021)
- Refund claim deadline: April 15, 2024
- Late filing penalty: 5% per month (up to 25%) of unpaid taxes
- How to file late returns:
- Gather all your tax documents (W-2s, 1099s, etc.)
- Use the same forms you would have used to file on time
- Mail your return to the appropriate IRS address (check IRS.gov for current addresses)
- If you owe taxes, include payment to minimize penalties and interest
- Special considerations:
- If you’re missing documents, request copies from the issuer or use IRS Form 4506-T to get transcripts
- Consider using IRS Free File (available until October) or commercial tax software
- If you can’t pay what you owe, the IRS offers payment plans
Our calculator can help you estimate what you owe or are due as a refund for these years before you file.
