Tax Residency · United States

# Working remotely from 🇺🇸 United States: when do you start owing taxes?

Tax residency triggers at **183 days** in any 365-day period — and crossing typically exposes your **whole year's income**.

## What residency would cost

| Annual income | Standard resident tax |
| --- | --- |
| $50,000 | $9,500 (19%) |
| $100,000 | $25,000 (25%) |
| $200,000 | $62,000 (31%) |

Approximate effective rates (income tax + typical employee contributions, single filer). Uses the weighted 3-year Substantial Presence Test, not a simple 183-day count — check the residency counter for the exact formula. Citizens are taxed regardless of residence. Count your actual days across countries in the [interactive tracker](https://geo-parity.com/tax-residency/).

## What you would actually keep

The table above is what tax residency costs. This is what is left, and what it buys at local prices — United States’s price level is **100%** of the US.

| Gross | Net after tax | Worth at US prices | Essentials covered |

| $50,000 | $40,500 | $40,500 | 1.4× |
| $100,000 | $75,000 | $75,000 | 2.6× |
| $200,000 | $138,000 | $138,000 | 4.8× |

Standard rates at the headline residency threshold, before any expat regime, deductions, social contributions or local surtaxes — the tax table above shows where a regime changes this. “Essentials covered” is how many times one month of net income covers a single person’s local monthly basket ( $2,410 /month here), so it measures headroom, not a lifestyle. Hand-curated summary of headline tax-residency thresholds and APPROXIMATE effective resident tax rates (income tax + typical employee social contributions, single filer, no deductions) at three income checkpoints, plus notable expat/nomad regimes. Real outcomes depend on tax treaties, ties, domicile, income type, and municipal taxes — this is an early-warning radar, not tax advice. Reviewed annually.

## Frequently asked questions

- **How long can I work remotely from United States without becoming tax resident?**: Up to 182 days in any 365-day period under the headline rule — day 183 triggers residency. Uses the weighted 3-year Substantial Presence Test, not a simple 183-day count — check the residency counter for the exact formula. Citizens are taxed regardless of residence.
- **How much tax would I owe in United States as a resident?**: Approximate effective rates: 19% at $50k, 25% at $100k, 31% at $200k (income tax plus typical employee contributions).
- **Does crossing the threshold only tax my income from that point on?**: Usually not — in most systems, becoming resident exposes your entire year's worldwide income. That cliff is why residency is a trap, not a gradient.
