## Who Counts as a U.S. Tax Resident Now?
Under U.S. tax law, you are a **resident for tax purposes** if you either meet the **green card test** or the **substantial presence test** (days spent in U.S.). Even if you are not a resident, the OBBB and related IRS guidance may impact foreign income and credit eligibility, particularly for clean energy, fuel, and entity-related credits.
## Foreign Income & Prohibited Foreign Entities (PFEs)
Digital nomads earning abroad may not interact with PFEs directly—but what you buy or invest in might.
- If you contribute to or invest in clean energy projects that include PFEs or non-approved feedstocks, credits or deductions may be denied. Notice 2026-15 outlines interim safe harbor rules for PFEs under §§ 45Y, 48E, 45X. ([irs.gov](https://www.irs.gov/newsroom/treasury-irs-provide-guidance-for-certain-energy-tax-credits-regarding-material-assistance-provided-by-prohibited-foreign-entities-under-the-one-big-beautiful-bill?utm_source=openai))
- The clean fuel production credit (45Z) imposes strict restrictions including geographic feedstock sourcing and eligibility. If part of your income or investments relate, document them.

## Deductions & Changes That May Help You
| Change | Helpful if You’re a Digital Nomad |
|---|---|
| Foreign Earned Income Exclusion (FEIE) | Unchanged by OBBB, still applicable—but income-based deductions/credits now stricter when PFEs or energy credits are involved. |
| New Standard Deductions & Senior Deduction | If you're eligible (age 65+), savings on taxes even without itemizing. If not, standard deduction is rising to keep pace with inflation. ([irs.gov](https://www.irs.gov/newsroom/irs-releases-tax-inflation-adjustments-for-tax-year-2026-including-amendments-from-the-one-big-beautiful-bill?utm_source=openai)) |
| Qualified Tips Deduction | If you do gig work or service work in multiple countries or U.S., tip deductions now available if occupation qualifies. Maintain evidence. |
## Structuring Income & Investments Smartly
1. **Use U.S.-safe investments** when claiming energy or clean fuel credits: prefer U.S., Canada, Mexico feedstocks/components. Avoid PFEs.
2. **Maintain Nonresident Status Carefully**: If you don’t want full U.S. taxation, manage your days in U.S. and ensure foreign source income qualifies — document permanent home abroad etc.
3. **Plan Capital Gains & Dividends**: Remain alert for proposed rules regarding controlled foreign corporations (CFCs) and transition rules under OBBB (dividends transition rule, etc.). ([irs.gov](https://www.irs.gov/irb/2025-52_IRB?utm_source=openai))
4. **File and Report Properly**: For credits and deductions that are new or modified, follow the most recent IRS rules and notices—form 637 for fuel, form 1099-K thresholds restored, safe harbors documented. ([irs.gov](https://www.irs.gov/newsroom/treasury-irs-issue-proposed-regulations-on-the-clean-fuel-production-credit-under-the-one-big-beautiful-bill?utm_source=openai))
## Practical Example
Say you live in Southeast Asia for 300 days/year, earn software consulting income, and invest $5,000 in a U.S. clean energy startup. The startup sources some components from PFEs. Under current interim guidance, eligibility for energy credits may be impacted if the material assistance from PFEs is too large. You can assess MACR, document ownership and safe harbor reliance, decide whether to invest via a structure that shields from PFE involvement.
## Final Tips
- Keep strong travel logs and evidence of nonresidency if that benefits you.
- Tag and separate foreign vs U.S. source income precisely.
- Before investing or working with businesses involved in energy or clean tech, get clarity on PFEs and eligibility.
- Use treasuries notices and safe harbors (e.g. Notice 2026-15, guidance on 45Z) as tools to mitigate risks.
Being mobile has tax advantages—but OBBB changes make planning more complex. Stay organized, document thoroughly, and seek advisors who are abreast of new regulations.
