Taxes
It depends on your case. The basics: your ID, the SSN or ITIN of everyone on your return, your W-2s or 1099s and your bank account. On the call we give you the exact list.
Yes. What you earn working for yourself has to be reported, even if nobody gives you a form. We help you add it up and subtract your work expenses.
For most people, April 15. If it falls on a weekend or holiday, the next business day counts.

Don't ignore it: many have a date to respond by. Bring us the whole letter and that year's return. We explain what it says, what they're asking for and how long you have.
Obamacare
There's an open enrollment period every year. In states that use HealthCare.gov, for 2027 it runs from November 1, 2026 to January 15, 2027. Some states have their own website and different dates.

Only if something happens that opens a special period: for example, losing job-based insurance, moving, getting married or having a baby. You usually have 60 days from the event. Tell us your case and we'll check it.

It depends on where you live, your immigration status and whether you already have insurance through work. The rules change from time to time: we check your case with the current year's rules.
It depends on your household income, how many of you there are and where you live. If your income is within certain limits, the government pays part of your premium every month. That's why it matters to estimate your yearly income well.
It's the share of medical costs the plan pays, on average: Bronze 60%, Silver 70%, Gold 80% and Platinum 90%. Extra savings on copays and deductibles only come with Silver plans.

It's best to review it every year during Open Enrollment: plans change and the help is based on that year's income.
Report it to the Marketplace as soon as you can. The help depends on your income and it's checked on your taxes with Form 1095-A: if you earned more than estimated, you may have to pay part of it back.
It's the form the Marketplace sends you if you had Obamacare, even for one month. It arrives by mail by mid-February, and it may be in your Marketplace account as early as mid-January. You need it to file your taxes, because it's used to check the help you received.

That too. We explain the options and how they fit with your health insurance.
ITIN
If they don't have a Social Security number and you're claiming them, they may need one. We'll tell you which documents the IRS asks for each of them.
Form W-7 and documents that prove who you are and where you're from, such as a valid passport. It's usually sent together with your tax return. We tell you what the IRS asks for in your case.
Explained in full inWhat to bring for the ITINSource: IRS, ITIN (opens in a new tab)
No. An ITIN is for your taxes only. According to the IRS, it doesn't authorize you to work, doesn't change your immigration status and doesn't qualify you for Social Security benefits.

If your ITIN expired and you need to file, it has to be renewed with the same Form W-7. We help you fill it out and prepare it together with your return.

Business & LLC
It depends on how it's registered. For the IRS, a single-member LLC, unless it elects otherwise, is reported on the owner's return; one with two or more members files as a partnership. We tell you which return yours files.

Paperwork
They check who you are with your ID and certify that you signed, in their presence. They don't give legal advice, don't draft the document and don't tell you which one you need.
Your photo ID and the unsigned document: you sign it in front of the notary public, at our office in Doral.
No. In Florida, a notary public can't certify copies of vital records, such as birth, marriage or death certificates. Those copies are requested from the office that keeps the record.

It depends on where you live. 9 of the 51 (50 states and DC) have no state tax on wages, like Florida and Texas. In the rest, besides the federal return, you file a state return.
Most do: 29 of the 51. The other 22 run their own insurance website, with their own dates. Your state's page tells you which one is yours.
If both states have an income tax, you may have to file in both, for the part of the year you lived in each. And if you have Obamacare, report your new address: moving can open a special period to change plans.
