PonticelloThe direct-indexing pipeline for US expats in Italy — S&P 500 exposure without the PFIC or IRPEF trap.
An opinionated, fully bundled direct-indexing service that turns the cross-Atlantic tax mess — PFIC Form 8621 complexity, PRIIPs friction, IVAFE tracking, IRPEF bracket creep — into a manageable near-zero-drag S&P 500 portfolio, run for the expat FIRE community rather than assembled by you.

The cross-Atlantic trap
Two tax systems. Both designed to grab the same gains.
Pick the US-domiciled S&P 500 ETF and Italy's IRPEF treats it as ordinary income at progressive rates. Pick the European UCITS and the IRS treats it as a PFIC — top ordinary rate plus interest charge. There is no offshore structure that is invisible to both.
Italy · IRPEF
Non-harmonized fund treatment
A US ETF is not on the harmonized fund whitelist, so gains and distributions route through the ordinary progressive brackets — not the 26% capital-gains regime. With regional and municipal surcharges the effective rate can reach roughly 46–47%.
Net: Italian side escalates with your other income.
IRS · PFIC
Passive Foreign Investment Company regime
Most Irish and Luxembourg UCITS wrappers trigger Form 8621. The IRS taxes distributions and gains at the top ordinary rate, plus a compounding interest charge on top of unrealized gains. Across a long horizon the PFIC surcharge alone can exceed half of total returns.
Net: US side compounds against you every year.
Italy · IVAFE
Foreign-held wealth tax
All foreign-held financial assets — ETF shares included — carry an IVAFE line at 0.2% per year, always tracked separately from income tax. Brokers report this on Quadro RW; it does not get folded into the IRPEF brackets but it is its own number to maintain.
Net: A bookkeeping tax independent of returns.
Both · wash-sale asymmetry
A 30-day window your broker may not know about
Most Italian brokers do not apply US wash-sale rules. A repurchase within 30 days disallows the loss on the 1040, while the Italy-side minusvalenza still goes into Quadro RT — leaving the two sides out of balance. The fix is process, not paperwork.
Net: Dual-sided loss math stops reconciling.
How it works
Four steps. One pipeline end to end.
Ponticello is the execution layer that sits on top of Interactive Brokers, runs the index, harvests losses, and reconciles both sides of the filing.
Read the FAQ- Step01
Open an Interactive Brokers account
A single brokerage that lets a US-tax person hold individual S&P 500 equities in Italy without triggering either side of the cross-Atlantic tax problem.
- Step02
Ponticello replicates the index
Our execution layer buys the 500 underlying constituents in the right weights, then keeps that basket in sync with the index as it rebalances — no packaged fund wrapper, no PFIC presentation.
- Step03
Wash-sale-aware harvesting runs quietly
Recent sells are flagged, the 30-day window is honored by parking cash or rotating into a correlated proxy, and each harvested minusvalenza is paired with the right legacy tax lot so the dual-sided logic comes out near net zero.
- Step04
Fills, dividends, cost basis, FX — one source of truth
ECB-dated FX conversions, dividends, lot-level cost basis and wash-sale notes stream straight into Italian fintech tooling such as Dichiarativo or MoneyViz, with Quadro RT, Redditi Diversi, Quadro RW, IVAFE and the regime dichiarativo pre-built.
Who this is for
Built for the expat FIRE community, not the generic retail investor.
Ponticello assumes an unusual reader — a US-tax citizen with Italian residency, accumulated wealth north of $100K, and no corporate tax advisor on retainer. If that's you, you are exactly the profile we built around.
A working profile
Marta, 47. US citizen, resident in Italy since 2018. Holds a six-figure taxable US brokerage, a small Italian pension, and a freelance income that puts her in the 38% IRPEF bracket.
- Wanting S&P 500 exposure without donating to the IRPEF or the PFIC regime.
- Tired of stitching together Quadro RT, Redditi Diversi, Quadro RW and IVAFE from broker CSVs in April.
- Wants the harvester, the wash-sale bookkeeping and the FX-dated cost basis handled — by someone, not on a spreadsheet.
