Account Simplification & Investment Plan

Dom Vinyard β€” April 2026


Current Accounts (6 β€” Too Many)

# Account Currency Purpose Interest
1 Monzo Current GBP UK spending 0%
2 Monzo Flex GBP BNPL N/A
3 Wise GBP GBP UK bills, rent receipt ~0%
4 Wise USD USD Salary receipt, US spending ~0%
5 SoFi Checking (joint) USD Joint household bills 0.50%
6 SoFi Savings (joint) USD Savings 3.30% (up to 4.00%)

Problem: None of these are optimized. Money sits in 0% accounts. Too many apps. No investment strategy.


Proposed Simplified Structure (3-4 accounts)

πŸ‡ΊπŸ‡Έ US Side (Where You Live)

1. SoFi Checking (joint) β€” KEEP

2. SoFi Savings (joint) β€” KEEP & MAXIMIZE

3. SoFi Invest or Separate Brokerage β€” NEW (see Investment section below)

πŸ‡¬πŸ‡§ UK Side (Rental Property + Occasional UK Spending)

4. Wise GBP β€” KEEP (simplified)

❌ CLOSE / PHASE OUT

Monzo Current β€” Close it. You're in the US. Wise GBP handles UK needs.

Monzo Flex β€” Pay off any remaining balance, then close.

Wise USD β€” Redirect salary to SoFi, then mostly retire this account.

Result: 3 Active Accounts + 1 Dormant

Account Purpose
SoFi Checking (joint) Salary, US bills, daily spending, rent
SoFi Savings (joint) Emergency fund, short-term savings
Wise GBP UK rent receipt + UK bills only
Wise USD (dormant) FX transfers only when needed

Apps needed: 2 (SoFi + Wise). Down from 4.


Roth IRA β€” The Cross-Border Question

Can You Open a Roth IRA?

Yes, absolutely. You're a US tax resident with earned income. You qualify.

2026 Contribution Limits

Your salary is ~$119K from Central plus GUSTO/Check Payroll income. If total MAGI is under $236K (married filing jointly), you're eligible for full contributions.

The UK-US Treaty Question

Good news: Roth IRA is one of the cleanest cross-border vehicles.

Under the US-UK tax treaty (Article 17), Roth IRA distributions are treated the same in the UK as they are in the US. The Treasury's Technical Explanation specifically states:

"A distribution from a U.S. Roth IRA to a UK resident would be exempt from tax in the United Kingdom to the same extent the distribution would be exempt from tax in the United States."

Translation: If you ever move back to the UK, qualified Roth IRA withdrawals are tax-free in BOTH countries. This is unusually clean for cross-border accounts.

⚠️ Important Caveats

  1. You must be a US tax resident to contribute. If you move back to the UK, you can no longer contribute β€” but existing funds continue to grow tax-free.

  2. HMRC stance changed in March 2025 on traditional IRA/401k lump sums (now taxable in UK with credit). Roth IRAs are not affected by this change because qualified distributions are already tax-free in the US.

  3. FBAR/FATCA reporting still applies to UK accounts (Wise, Monzo) β€” you should already be reporting these. If you're not, flag this with Andrew Parsons.

  4. Five-year rule: Roth IRA must be open 5+ years and you must be 59Β½+ for fully qualified (tax-free) distributions. Start now = clock starts ticking now.

Recommendation: Open a Roth IRA. Max it out annually ($7,000 each β€” you and Brianna).

Combined: $14,000/year in tax-free growth. Over 20 years at 7% average return, that's roughly $575,000 in tax-free money.


Investment Strategy

SoFi Invest β€” Is It Good Enough?

For simplicity: Yes, SoFi Invest is fine.

vs. Vanguard/Fidelity:

Verdict: If you want minimal apps, open the Roth IRA at SoFi. You can buy the same index ETFs (VTI, VXUS, BND) on any platform. The 1% IRA match is a nice SoFi-specific bonus.

If you want the absolute best platform and don't mind one more app, Fidelity edges out for index investing (zero-fee index funds, better tools, better customer service).

Joint vs. Solo Investments?

Retirement accounts (Roth IRA): Always individual. IRAs are individual by definition β€” no joint IRAs exist. Each person opens their own.

Taxable investing: You have options:

Recommended Setup

Account Type Who Where Monthly
Roth IRA Individual Dom SoFi or Fidelity $583 ($7,000/yr)
Roth IRA Individual Brianna SoFi or Fidelity $583 ($7,000/yr)
Taxable brokerage Joint Both Same platform Whatever's left after bills/emergency

What to Invest In (Keep It Simple)

A classic three-fund portfolio:

Fund Allocation Expense Ratio What It Is
VTI (Vanguard Total Stock Market) 60% 0.03% All US stocks
VXUS (Vanguard Total International) 30% 0.07% All non-US stocks
BND (Vanguard Total Bond Market) 10% 0.03% US bonds

Or if using Fidelity's zero-fee funds:

Fund Allocation Expense Ratio
FZROX (Fidelity Zero Total Market) 60% 0.00%
FZILX (Fidelity Zero International) 30% 0.00%
FXNAX (Fidelity US Bond Index) 10% 0.025%

Set it, forget it, rebalance once a year.

⚠️ I'm not a financial advisor. Cross-border tax situations are complex. Confirm Roth IRA eligibility and FBAR obligations with Andrew Parsons (Price Bailey) or a US-UK specialist tax advisor before executing.
