AI ASSISTANT
I'm in the 24% bracket earning $120k. How much can I save by maxing my 401(k) at $23,000?

Maxing your 401(k) at the 2025 limit would save you $5,520 in federal tax (24% bracket) plus state savings. Pre-tax contributions also reduce your AGI for other credits.

WHY AI TAXPILOT

Three things government tax tools will never do.

🤖

An AI that actually reads the tax code

Ask any tax question in plain English. The AI runs the same calculator tools an accountant would — every figure is grounded, never made up.

🏦

Your bank, into your return

Open Banking pulls 12 months of transactions, AI categorises them into the right tax buckets in seconds. One click pre-fills your return.

🌐

UK + US in one place

The only assistant built for dual-tax residents. Live FX, treaty-aware calculations, Foreign Earned Income Exclusion, FBAR reminders — all in a single consolidated view.

HOW IT WORKS

From question to answer in three steps.

01

Ask in plain English

Type or speak any US tax question — "what's my federal tax?", "how much can I max in my 401(k)?", "what's my take-home on $120k?". No jargon required.

02

AI runs the real maths

AI TaxPilot calls live IRS calculator tools — the same ones a CPA would use. Every figure is grounded in a tool result, never made up.

03

Get a verified answer

See the number, the breakdown and the marginal rate — and one click to open the same calculation in a full calculator and export to PDF.

FAQ

The questions people ask before signing up.

Will the AI make up numbers?

No. The AI calls live IRS calculator tools for every figure — it can't output a tax number without a tool call. We surface which calculators it ran, so you can verify any figure independently and open the same calculation in a full calculator.

Are the rates kept up to date?

Yes. We track IRS rate announcements and have shipped rate updates within 24 hours of every IRS bulletin and state DOR change since launch. Every calculator displays the tax year it's using and a "last updated" timestamp.

Can it replace my CPA?

For most personal tax situations — W-2 take-home, basic 1040, simple Schedule E rentals, salary/distribution optimisation, retirement planning — yes. For complex matters (IRS examinations, multi-state filings, K-1 partnerships, large estate planning) you still want a licensed CPA or EA; AI TaxPilot is a great prep tool that saves them time.

How does the bank integration work?

We use Plaid to connect to any major US bank or credit union. You authorise once, we pull the last 12 months of transactions, the AI categorises every line, and one click pre-fills your Schedule C, Schedule E, or 1099 deduction list. We never store credentials and you can revoke access from your bank or our app any time.

Is my data safe?

Your tax data lives in encrypted Postgres (Supabase, US region) with row-level security so only your account can see it. We never use your data to train models. Bank connections are read-only and you control the data window per provider. Read our Security page for the full technical detail.

What happens after my 14-day trial?

On day 14, your card is charged the Plus monthly price (or annual if you picked annual). If you cancel before then, no charge. Cancellation is one click in Settings and takes effect immediately — no email-the-CEO routine.

Do you offer student / military / nonprofit pricing?

Yes — 50% off Plus for verified students, US military (active duty + veterans), and registered 501(c)(3) nonprofits. Email support@aitaxpilot.com with proof and we'll send you a discount code.

Can I export everything as PDF?

Every calculator has an Export to PDF button that produces a clean printable summary including IRS bracket breakdowns, your inputs and the resulting figures. Useful for your records or sending to your CPA.
