Form 1040-ES Estimated Tax Filing Checklist for Tax Year 2019
Understanding the 2019 Form 1040-ES Requirements
The 2019 Form 1040-ES reflects continued implementation of Tax Cuts and Jobs Act provisions, including increased standard deductions and the elimination of the ACA shared responsibility payment. For 2019, the federal individual mandate penalty was reduced to zero, meaning taxpayers no longer face tax penalties for lacking health insurance coverage. Standard deductions increased to $12,200 for single and married filing separately, $24,400 for married filing jointly or qualifying widow, and $18,350 for head of household.
The Social Security wage base increased to $132,900 for 2019. The adoption credit maximum increased to $14,080 per eligible child, with a phaseout beginning at a modified adjusted gross income of $211,160. These adjustments directly impact estimated tax calculations and require careful consideration when projecting quarterly payment obligations throughout the year.
Who Must File Form 1040-ES for 2019
You must make estimated tax payments for 2019 if you expect to owe at least $1,000 in tax after subtracting withholding and refundable credits, and your withholding and credits will be less than the smaller of 90% of your 2019 tax liability or 100% of your 2018 tax liability. Higher income taxpayers with adjusted gross income exceeding $150,000 on their 2018 return must pay 110% of their prior year tax to satisfy safe harbor requirements. Farmers and fishermen may pay 66⅔% of their current year tax.
Self-employed individuals, freelancers, independent contractors, gig economy workers, investors with substantial dividend or capital gains income, and rental property owners are typically required to file estimated tax payments.
10-Step Filing Process for 2019 Estimated Tax
1. Gather All 2018 Tax Documents
Collect your complete 2018 tax return with all schedules. Gather Forms W-2, all Forms 1099, Schedule K-1 forms, and Form 1095-A if you purchased health insurance through the Health Insurance Marketplace. Review your 2018 adjusted gross income, total tax liability, and withholding amounts, as these establish the foundation for calculating your 2019 estimated payments using safe harbor rules.
2. Project Your 2019 Income and Calculate AGI
Estimate all expected 2019 income, including wages, self-employment earnings, business profits, rental income, interest, dividends, capital gains, and retirement distributions. Calculate your expected adjusted gross income by accounting for above-the-line deductions, including the self-employment tax deduction, health savings account contributions, and qualified business income deduction under Section 199A if applicable. Remember that personal exemptions remain suspended for 2019.
3. Calculate Self-Employment Tax
If you have self-employment income, multiply your expected net profit by 92.35% to determine the amount subject to self-employment tax. Apply Social Security at 12.4% on earnings up to $132,900, and Medicare at 2.9% on all self-employment income. Multiply your total self-employment tax by 50% to calculate the deductible portion that reduces your adjusted gross income.
4. Determine Deductions and Calculate Taxable Income
Determine whether to itemize deductions or claim the standard deduction: $12,200 for single or married filing separately, $24,400 for married filing jointly or qualifying widow, or $18,350 for head of household. Itemized deductions include a $10,000 cap on state and local taxes. Medical expenses must exceed 10% of adjusted gross income for 2019 to be deductible. If eligible, calculate your qualified business income deduction under Section 199A.
5. Apply Tax Rate Schedules and Calculate Base Tax
Use the 2019 Tax Rate Schedules to calculate your tax liability: 10%, 12%, 22%, 24%, 32%, 35%, and 37%. Qualified dividends and long-term capital gains receive preferential rates of 0%, 15%, or 20% depending on your income level. Consult Publication 505 worksheets to calculate tax on preferential income.
6. Account for Health Coverage and Marketplace Credits
While the shared responsibility payment has been eliminated for 2019, you should still indicate on your return whether you had health coverage. If you received advance premium tax credits through the Health Insurance Marketplace, consider how income changes will affect your final credit reconciliation on Form 8962. Promptly report income or family size changes to your Marketplace to adjust advance payments.
7. Calculate Credits and Total Tax Liability
The child tax credit provides $2,000 per qualifying child under the age of 17, with up to $1,400 of the amount being refundable. Your child must have a Social Security number to qualify. The credit for other dependents provides $500 per dependent who is not eligible for the Child Tax Credit. Also consider education credits, retirement savings contributions credit, earned income credit, and dependent care credit. Add your income tax and self-employment tax, then subtract your expected credits to determine your estimated total tax liability.
8. Determine Required Quarterly Payment Amounts
Calculate your required annual estimated tax payment using safe harbor provisions. Pay the smaller of 90% of your expected 2019 tax liability or 100% of your 2018 actual tax liability. If your 2018 adjusted gross income exceeded $150,000, pay 110% of your 2018 tax. Divide your required annual payment by four to determine the amount of each quarterly installment. If income varies significantly, consider using the annualized income installment method with Form 2210 and Schedule AI.
9. Submit Payments by Designated Due Dates
Make estimated tax payments by the quarterly due dates: April 15, 2019, June 17, 2019, September 16, 2019, and January 15, 2020. Note that June and September dates reflect adjustments because June 15 and September 15 fall on weekends in 2019. You may pay all estimated tax by April 15, or skip the January 15 payment if you file your 2019 return by January 31, 2020, and pay the entire balance due. Farmers and fishermen with at least two-thirds of gross income from farming or fishing can pay all estimated tax by January 15, 2020, or file by March 2, 2020.
10. Choose Your Payment Method and Track Payments
Submit payments using Form 1040-ES vouchers when paying by check, or pay electronically through IRS Direct Pay, the Electronic Federal Tax Payment System, or by debit or credit card through authorized service providers, including WorldPay US Inc., Official Payments, and Link2Gov Corporation. Cash payments up to $1,000 per day are available through retail partners. Mail vouchers to the appropriate address based on your state of residence. Maintain detailed records of all payment dates, amounts, confirmation numbers, and any overpayment credits applied from the prior year.
Critical Considerations for 2019 Tax Compliance
Taxpayers with fluctuating income should consider the annualized income installment method, which matches estimated payments to actual income earned during each period. This method proves valuable for seasonal businesses, farmers and fishermen, investors receiving significant capital gains late in the year, or anyone experiencing significant income fluctuations. File Form 2210 with Schedule AI when using this approach to document your calculations and demonstrate compliance.
Monitor your income, deductions, credits, and health coverage throughout the year and promptly adjust your estimated payments when circumstances change materially. Increase payments if income rises beyond projections or expected credits fail to materialize. Consider reducing subsequent payments if income drops substantially or deductible expenses increase significantly.
Use the IRS Withholding Calculator at IRS.gov/W4App to determine whether you need to adjust your withholding. Many taxpayers benefited from the TCJA changes through revised withholding tables; however, individual circumstances vary. Keep copies of all vouchers, payment confirmations, and supporting worksheets for your records. These documents provide essential documentation if questions arise about your estimated tax payments and serve as valuable references when preparing your annual tax return.
Understanding the elimination of the shared responsibility payment simplifies 2019 estimated tax calculations, as you no longer need to account for potential penalties related to health coverage. However, maintaining qualifying coverage remains crucial for health and financial security, and individuals receiving advance premium tax credits must still reconcile these credits on their annual tax return.
