Puerto Rico residents who are self-employed file Form 1040-SS, the U.S. Self-Employment Tax Return, which replaced the Spanish-language Form 1040-PR starting with the 2023 tax year.1Internal Revenue Service. About Form 1040 (PR) Self-Employment Tax Return – Puerto Rico If your net self-employment earnings reach $400 or more in the tax year, you owe federal self-employment tax at a combined rate of 15.3% for Social Security and Medicare, even if you have no obligation to file a federal income tax return.2Internal Revenue Service. About Form 1040-SS, U.S. Self-Employment Tax Return The instructions below walk through who files, how the tax is calculated, when to pay, and how to submit the return.
Who Must File
You must file Form 1040-SS if you are a bona fide resident of Puerto Rico and your net earnings from self-employment reach $400 or more during the tax year. The requirement applies regardless of your age, and it applies even if you already receive Social Security or Medicare benefits.2Internal Revenue Service. About Form 1040-SS, U.S. Self-Employment Tax Return That $400 floor sits well below the gross income levels that trigger a federal income tax return, which is why many self-employed Puerto Rico residents owe self-employment tax without owing any income tax.
Bona fide residency for a tax year turns on three tests: a presence test showing enough time on the island, a tax home test confirming your principal place of business is in Puerto Rico, and a closer connection test showing stronger ties to Puerto Rico than to the mainland or a foreign country.3Internal Revenue Service. Publication 1321 – Special Instructions for Bona Fide Residents of Puerto Rico
Form 1040-SS handles two other jobs as well. If you paid cash wages of $3,000 or more to a single household employee during 2026, you report the employment taxes on Schedule H and attach it to this return.4Internal Revenue Service. Topic No. 756, Employment Taxes for Household Employees Puerto Rico residents also use the form to claim the Additional Child Tax Credit, which is covered further down.
Clergy Exemption
Ordained ministers, members of religious orders who have not taken a vow of poverty, and Christian Science practitioners can apply for exemption from self-employment tax on ministerial earnings by filing Form 4361.5Internal Revenue Service. About Form 4361, Application for Exemption From Self-Employment Tax for Use by Ministers, Members of Religious Orders and Christian Science Practitioners Approval is permanent, and those earnings then stay off Form 1040-SS. Opting out also means giving up Social Security credit for that work.
Figuring Net Earnings from Self-Employment
Your tax starts with net earnings from self-employment, or NESE. Begin with gross business income and subtract ordinary and necessary business expenses. Gross income includes revenue from a sole proprietorship, your share of partnership income, and guaranteed payments from a partnership.
Some income does not count. Rental income from real estate (unless you are a real estate dealer), investment income such as dividends and interest, and gains or losses from selling business property are generally excluded from NESE. Calculate the initial profit or loss on Schedule C for a trade or business, or Schedule F for farming, and attach the schedule to Form 1040-SS.
Only 92.35% of your net profit is subject to self-employment tax.6Internal Revenue Service. Topic No. 554, Self-Employment Tax The reduction reflects the fact that traditional employers pay half of FICA on behalf of their workers. So a $50,000 Schedule C net profit produces taxable NESE of $46,175.
Calculating the Self-Employment Tax
Self-employment tax runs at a combined 15.3%: 12.4% for Social Security and 2.9% for Medicare.7Internal Revenue Service. 8Social Security Administration. Contribution and Benefit Base NESE above that is exempt from the Social Security piece. If you also received wages from an employer during the year, those wages fill the cap first and reduce the self-employment income that gets hit with the 12.4%.
Medicare has no cap. The 2.9% applies to every dollar of NESE. An additional 0.9% Medicare tax applies to self-employment income above the following thresholds:9Internal Revenue Service. Topic No. 560, Additional Medicare Tax
- Married filing jointly: $250,000
- Married filing separately: $125,000
- All other filers: $200,000
A Worked Example
Say your Schedule C shows $80,000 in net profit for 2026 and you had no wages from an employer. Taxable NESE is $73,880 ($80,000 × 0.9235). The Social Security tax is $9,161 ($73,880 × 12.4%), and the Medicare tax is $2,143 ($73,880 × 2.9%). Total self-employment tax comes to $11,304. NESE sits below the $184,500 Social Security cap, so the full amount is subject to the 12.4%, and because it is under $200,000, no Additional Medicare Tax applies.
Claiming the Additional Child Tax Credit
Bona fide residents of Puerto Rico can claim the Additional Child Tax Credit (ACTC) directly on Form 1040-SS. The older rule that required three or more qualifying children no longer applies. One qualifying child is enough.10Internal Revenue Service. Instructions for Form 1040-SS (2025)
The credit is worth up to $1,700 per qualifying child under age 17.11Internal Revenue Service. Publication 4281 (PR) – Resources for Puerto Rico Families You need earned income of at least $2,500 to qualify.12Internal Revenue Service. Child Tax Credit The ACTC is refundable. If you file Form 1040-SS only for self-employment tax, the credit can offset part or all of that liability, and any excess is refunded to you.
Quarterly Estimated Tax Payments
If you expect to owe $1,000 or more in self-employment tax for the year after subtracting any withholding and refundable credits, the IRS generally requires quarterly estimated payments rather than one payment at filing time.13Internal Revenue Service. Instructions for Form 1040-SS Use Form 1040-ES to compute the amount and to generate the vouchers you send with each installment.
For the 2026 tax year, the quarterly deadlines are:
- First quarter: April 15, 2026
- Second quarter: June 15, 2026
- Third quarter: September 15, 2026
- Fourth quarter: January 15, 2027
Missing a deadline triggers an underpayment penalty based on the shortfall, the length of the delay, and the IRS’s quarterly interest rate.14Internal Revenue Service. Underpayment of Estimated Tax by Individuals Penalty The penalty compounds quickly on substantial self-employment income, so it is worth getting the first quarter right.
Filing and Paying
Form 1040-SS for the 2026 tax year is due April 15, 2027. You can request an automatic six-month extension by filing Form 4868 by that date, which moves the filing deadline to October 15, 2027.15Internal Revenue Service. Form 4868, Application for Automatic Extension of Time to File U.S. Individual Income Tax Return An extension moves the filing date only. Tax owed is still due April 15, and anything unpaid after that starts accruing penalties and interest.
E-Filing
Form 1040-SS can be filed electronically. You sign it with a five-digit PIN you create yourself, or your preparer can enter or generate one for you.10Internal Revenue Service. Instructions for Form 1040-SS (2025) E-filing is faster and cuts down on errors.
Paper Filing Addresses
If you file on paper, the address depends on whether you’re sending a payment:16Internal Revenue Service. Where to File Forms 1040-NR, 1040-PR, and 1040-SS
- With payment: Department of the Treasury, Internal Revenue Service, Austin, TX 73301-0215, USA
- Without payment: Internal Revenue Service, P.O. Box 1303, Charlotte, NC 28201-1303, USA
Payment Methods
You can pay by check or money order payable to “United States Treasury” and mail it with your paper return. Electronic options include IRS Direct Pay, which debits your bank account, and the Electronic Federal Tax Payment System (EFTPS), which requires advance enrollment. Debit card, credit card, and digital wallet payments go through IRS-authorized processors and carry processing fees.
Penalties for Filing or Paying Late
Filing late and paying late are separate penalties, and they stack. The failure-to-file penalty is 5% of the unpaid tax for each month or part of a month the return is overdue, up to 25%. If the return is more than 60 days late, the minimum penalty rises to $525 or 100% of the unpaid tax, whichever is less.17Internal Revenue Service. Failure to File Penalty
The failure-to-pay penalty is 0.5% of the unpaid tax for each month the balance is outstanding, also capped at 25%.18Internal Revenue Service. Topic No. 653, IRS Notices and Bills, Penalties and Interest Charges That rate doubles to 1% if the IRS sends a notice of intent to levy and the balance still isn’t paid within 10 days. If you file on time and set up an installment agreement, the monthly rate drops to 0.25%.
Interest runs on top of both penalties and compounds daily from the original due date. If you can’t pay the full amount, file the return on time anyway. The failure-to-file penalty is ten times larger than the failure-to-pay penalty in the early months, and getting the return in by the deadline is the single most effective way to limit what you owe.
