Working for yourself in Puerto Rico, whether as a consultant, contractor, technician, health professional, designer or driver, comes with more tax responsibilities than a salaried job. No one withholds Social Security for you, you have to keep your own records and, in many cases, you have to pay estimated tax during the year. This guide summarizes the main points, based on the instruction booklet from the Departamento de Hacienda (Puerto Rico's Treasury Department, "Hacienda") for tax year 2025 and the Código de Rentas Internas de Puerto Rico de 2011 (Internal Revenue Code of Puerto Rico).
Before you start: registration and permits
To operate a business, even a one-person business, you need a Certificado de Registro de Comerciante (merchant registration certificate) from Hacienda, which you get in SURI (Hacienda's online system). According to Hacienda, a current registration is also a requirement for a self-employed worker to claim the Crédito por Trabajo (Puerto Rico's earned income credit). Read Registro de Comerciantes.
Depending on your activity, you might also have to pay the patente municipal (municipal license tax) and charge IVU (sales and use tax) on certain services. These are obligations separate from income tax.
The 10% withholding on services
Section 1062.03 of the Code provides that the government and any person who, in the course of their business, pays you for services rendered in Puerto Rico must withhold 10% of each payment. The main rules:
- First $500. No withholding is required on the first $500 a payer pays you during the calendar year.
- Exceptions. It does not apply to certain payments, such as those made to hospitals and to exempt organizations, among others. It also does not apply to purchases of goods or to property rentals.
- More withholding, if you want. You can ask them to withhold 15% or 20%, or the top rate of the optional tax, so you do not have to pay as much when you file.
- Waiver. If you meet the requirements, Hacienda can authorize lower withholding. Those who choose the optional tax can get a partial waiver so that 6% is withheld, according to Carta Circular de Rentas Internas Núm. 19-16 (an internal revenue Circular Letter).
At the start of the year, each payer gives you Form 480.6SP (Declaración Informativa de Servicios Prestados, the informative return for services rendered) showing what it paid you and what it withheld. That withholding is a payment toward your tax. See withholding and forms.
How your tax is calculated
You have two paths on the income tax return (planilla, Form 482).
Path 1: regular tax with expenses
You report your business income and expenses on the matching schedule (Anejo M Individuo, the schedule for services rendered). Your net profit is added to your other income and the tax rate table applies.
Expenses must be ordinary, necessary and directly related to your business. According to the booklet, several expenses are deductible only if they are reported on an informative return. For example, payments for services that you make to others are deductible if you reported them on Form 480.6SP and deposited the corresponding withholding, and advertising, telecommunications or internet expenses require informative Form 480.7E or 480.7F to count for the alternate basic tax.
Path 2: the optional tax (Anejo X Individuo)
Section 1021.06 of the Code lets certain self-employed workers pay a flat rate on their gross income instead of using the regular table. In exchange, you do not subtract expenses or deductions. According to the 2025 booklet, to qualify:
- at least 80% of your gross income for the year must come from providing services; and
- your income must have been subject to withholding at the source or to estimated tax payments. If you have a balance due, you must pay it in full no later than the return's deadline, not counting the extension (for 2025, April 15, 2026).
| Gross income | Optional tax |
|---|---|
| Not more than $100,000 | 6% |
| More than $100,000 up to $200,000 | 10% |
| More than $200,000 up to $300,000 | 13% |
| More than $300,000 up to $400,000 | 15% |
| More than $400,000 up to $500,000 | 17% |
| More than $500,000 | 20% |
Isabel is a single graphic designer, and in 2025 she billed $60,000 in services. All of her income comes from services. With the optional tax, she pays 6% × $60,000 = $3,600. If she used the regular tax instead and had $12,000 in business expenses, her net taxable income would be $60,000 − $12,000 − $3,500 = $44,500, and the table would give $3,430 + 25% × $3,000 = $4,180, which with the 92% reduction comes to $3,845.60. In her case, the optional tax is lower, but with more expenses the result can change.
Keep in mind that, according to Hacienda's guidance, those who paid under the optional tax in 2025 did not qualify for the tax relief in Resolución Conjunta (Joint Resolution) 6-2026.
Estimated tax
If you are an employee, withholding covers almost all of your tax. If you are self-employed, it may not. According to the booklet, you must pay estimated tax if you expect your tax for the year, minus withholding and credits, to be more than $1,000. For a calendar year, the installments are due:
- April 15,
- June 15,
- September 15, and
- January 15 of the following year.
You pay them electronically in SURI. If you do not pay on time, the Code imposes a 10% addition on the unpaid installment. To avoid it, it is generally enough to pay the lesser of 90% of the year's tax or, if you filed a 12-month return showing tax the prior year, that year's tax. There are different installment dates if the obligation arises later in the year, and special rules for farmers.
Federal Social Security (Form 1040-SS)
Even if you do not owe income tax to the IRS on your Puerto Rico income, you do have to pay the federal self-employment tax, which funds your Social Security and Medicare. According to Hacienda and the IRS, if your net self-employment earnings are $400 or more, you must file Form 1040-SS with the IRS.
How it is calculated. The base is 92.35% of your net earnings. On that base you pay 15.3%: 12.4% for Social Security, up to an earnings cap the Social Security Administration sets each year, and 2.9% for Medicare, with no cap. The cap for the Social Security portion was $176,100 in 2025 and is $184,500 in 2026. If you also have wages, they count first toward that cap.
Tomás had $40,000 in net self-employment earnings in 2025 and no wages. Base: $40,000 × 92.35% = $36,940. Self-employment tax: $36,940 × 15.3% = $5,651.82.

Form 1040-SS is also where Puerto Rico families claim the federal Child Tax Credit. Read Social Security for self-employed workers and the child tax credit.
Records you should keep
- Invoices and receipts for everything you bill.
- Every Form 480.6SP you receive and every one you issue.
- Receipts for business expenses, with proof of payment.
- Confirmations of estimated tax payments.
- Copies of your Hacienda and IRS returns.
Hacienda asks you to keep the evidence for at least six years.
Frequently asked questions
Is the optional tax a good idea for me?
It depends on your expenses and your other income. The optional tax tends to favor people with few expenses, because it does not let you subtract them. If your expenses are high, the regular table may come out lower. Calculate both before you decide. A CPA or tax return specialist can help you compare.
A client did not withhold the 10%. What happens?
You still have to report that income and pay the tax that applies. Withholding is the payer's obligation, but your tax is yours. If that income leaves you with a large balance, consider paying estimated tax.
I have a job and also do work on my own. What applies?
Both. Your wages go on the return with your withholding statement, and your self-employment income goes on the matching schedule. For the optional tax, the 80% requirement is measured against your total gross income for the year, so your other income can affect whether you qualify. Review Anejo X Individuo carefully. For Form 1040-SS, only self-employment earnings count, although your wages count first toward the Social Security cap.
What happens if I did not pay estimated tax on time?
The Code imposes a 10% addition on the unpaid amount of each installment, which is calculated on Anejo T Individuo of the return. Paying the missing installments as soon as possible reduces the problem. If you already have a balance you cannot pay, see payment plans with Hacienda.
