First time doing taxes? Same.

TaxplAIn explains your taxes in plain English. No jargon, no lectures, and no
pretending it's simpler than it is. Ask a question, or answer about nine of
ours and find out what you're actually getting back.

WHAT YOU GET, FREE
• Ask anything about your taxes. Every answer cites a real IRS publication, so
you can check us rather than trust us.
• Work out your refund, or what you owe. Same tax engine the website uses.
• The forms you'll actually need, with a plain reason for each one.
• Where you could save, in words instead of spreadsheets.

BUILT FOR PEOPLE FILING FOR THE FIRST TIME
Gig work and the 1099-NEC. Reselling and the 1099-K. Your first W-2 and why the
paycheck was smaller than you expected. Student loan interest. Scholarships.
Being claimed as a dependent while filing your own return. "Do I even have to
file?", which is the most common question there is, and has a short answer.

WE DON'T WANT YOUR SSN
There is nowhere in this app to type a Social Security number. That isn't a
policy we promise to follow: the fields don't exist. Your email is the whole
account: no name, no card. Your answers and your chat stay on your phone.

HOW THE NUMBERS WORK
Every figure comes from a deterministic tax engine, not from an AI guessing.
The AI explains what the engine calculated. It never does the arithmetic. When
we can't answer something from a verified source, we say so instead of
inventing an answer.

GUIDANCE, NOT TAX ADVICE
We explain your taxes and estimate your numbers. We are not licensed tax
advisors, and we won't pretend otherwise. Have a CPA or tax professional check
your return before you file.
