A guided interview that fills out Form 3520 and Form 3520-A for you, the forms that TurboTax won’t touch and a specialist charges four figures for. Answer plain-English questions, get a print-ready return.
Miss a Form 3520 and the penalties are steep. See how each one works. TurboTax doesn’t support the form, and H&R Block’s software doesn’t either. Your options have been a specialist who charges four figures or a blank IRS PDF and a prayer.
File3520 is a guided interview that asks plain-English questions and produces a completed, print-ready form. The same result, a fraction of the cost. Learn more about Forms 3520 & 3520-A.
Report gifts or bequests exceeding the annual thresholds: more than $100,000 from one nonresident alien individual or foreign estate (adding together gifts from donors related to each other), or $20,116 (2025) / $20,573 (2026) from foreign corporations or partnerships. Usually no tax owed, but the report is mandatory. Enter amounts, identify the donors, and generate a print-ready Part IV.
See this in the demo →For U.S. persons who create or put money or property into a foreign trust (Part I), or are treated as its owner under the grantor trust rules (§§671–679). We walk through Parts I and II and produce the companion Form 3520-A: balance sheet, income statement, and owner statements included. Workplace pensions an employer pays into are covered too: no Part I, and you own only the part your own contributions fund, once they exceed your employer’s.
See this in the demo →Received a distribution from a foreign trust? We apply the throwback rules, track accumulation distributions from year to year, add your earlier ones back into each prior year’s income, from this trust or any other, and auto-generate Form 4970 when the tax applies. Payouts from a workplace pension that you report as pay need no Part III.
See this in the demo →For a trustee filing the trust’s own Form 3520-A: balance sheet, income statement, and beneficiary/owner statements. If the foreign trust does not file its own Form 3520-A, the U.S. owner must complete and attach a substitute to their Form 3520: the trust owner path produces one.

Received a foreign trust distribution and a reportable foreign gift in the same year? Part III and Part IV go onto one Form 3520 for that filer and tax year, with one set of header answers. Each foreign trust still gets its own Form 3520: the form says so at the top of page 1.
Not just for individuals. Partnerships, C-corps, S-corps, trusts, and executors can file with entity-specific handling: fiscal year support, the right tax return number on line 1k (1120, 1120-S, 1065, 1041…), and signing-title fields.
Every filing generates a cover page with filing instructions, the completed IRS form, computation worksheets, a retrace worksheet that ties every number back to the source, and supplemental statements when entries overflow the printed form.
Throwback-rule calculations, Form 4970 accumulation distributions, §668 interest charges. The engine handles them end to end. You enter the facts; the math is ours to get right.
“Did I get the throwback math right?”
The engine shows its work on every line so you can verify the numbers before you file.
We ask what happened - a gift, a trust, a distribution - and route you to only the parts that apply.
Your answers map onto the actual IRS lines. No jargon, no blank boxes to decode.
