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)
πΊπΈ US Side (Where You Live)
1. SoFi Checking (joint) β KEEP
- Salary flows here (redirect from Wise)
- Joint bills: BMW, GEICO, PG&E, Comcast, insurance
- Rent ($4,900/mo via Venmo)
- This is your operating account
2. SoFi Savings (joint) β KEEP & MAXIMIZE
- Emergency fund: 3 months expenses (~$15,000β20,000)
- Currently earning 3.30% APY (or 4.00% with direct deposit/SoFi Plus)
- This is already competitive β top HYSAs are 3.80β4.35%
- You could squeeze ~1% more at Newtek (4.35%) or Openbank (4.20%), but it's not worth another app for the marginal gain on a modest balance
3. SoFi Invest or Separate Brokerage β NEW (see Investment section below)
π¬π§ UK Side (Rental Property + Occasional UK Spending)
4. Wise GBP β KEEP (simplified)
- Receives Hamptons Estates rent (Β£1,800β2,100/mo)
- Pays UK-specific bills: EE, Admiral insurance, HMRC
- Wise has no monthly fees and decent FX rates β it's the right tool for cross-border
β CLOSE / PHASE OUT
Monzo Current β Close it. You're in the US. Wise GBP handles UK needs.
- Transfer any remaining balance to Wise GBP
Monzo Flex β Pay off any remaining balance, then close.
- You're putting recurring subscriptions on BNPL β that's a sign of cash flow disorganization, not need
- Route those subscriptions to Wise or SoFi directly
Wise USD β Redirect salary to SoFi, then mostly retire this account.
- Keep it open with minimal balance for occasional USDβGBP transfers (Wise FX rates are excellent)
- But it shouldn't be your primary USD account anymore β SoFi is better (FDIC insured, earns interest, joint)
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
- Under 50: $7,000/year
- Income limit (single): Phase-out starts at $150,000 MAGI, fully out at $165,000
- Income limit (married filing jointly): Phase-out starts at $236,000, fully out at $246,000
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.
β οΈ Important Caveats
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.
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.
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.
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.
- Zero commissions on stocks/ETFs
- Roth IRA available with 1% match for SoFi members
- Fractional shares available
- Financial advisor access included
vs. Vanguard/Fidelity:
- Vanguard has lower expense ratios on their own funds (but you can buy VTI/VXUS on SoFi too)
- Fidelity has better research tools and zero-expense-ratio index funds (FZROX, FZILX)
- But both require another app/account
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:
- Joint brokerage account: Simpler. One account, both names. Either can trade. But all gains/losses are shared and reported on both tax returns.
- Individual brokerage accounts: More flexibility. Each person controls their own. Better if one person is more active or has different risk tolerance.
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.
Cash Flow Redesign
Current Flow (Messy)
Central salary ($5,400 bi-weekly) β Wise USD β manual transfers everywhere
Hamptons rent (Β£1,800/mo) β Wise GBP β UK bills
Random Monzo spending β Flex for overflow
Wise β SoFi transfers β Venmo rent ($4,900) β bills
Proposed Flow (Clean)
Central salary ($5,400 bi-weekly) β SoFi Checking
βββ Auto-pay: Rent ($4,900 Venmo), BMW, GEICO, PG&E, Comcast, insurance
βββ Auto-transfer: $583/mo β Dom's Roth IRA
βββ Auto-transfer: $583/mo β Brianna's Roth IRA
βββ Auto-transfer: $1,000/mo β SoFi Savings (emergency fund build)
βββ Remaining: daily spending
Hamptons rent (Β£1,800/mo) β Wise GBP
βββ Auto-pay: EE, Admiral, any UK bills
βββ Surplus: accumulate for HMRC/accountant payments
No more Monzo. No more Flex. No more manual shuffling.
