What Is the Process for Filing Both My US and UK Expat Tax Returns? Will I Have to Upload Everything Twice?

No, you won’t need to upload your documents twice. Greenback makes it simple to file your US and UK tax returns through a single, secure portal and a team that works together behind the scenes, saving you time, stress, and money.

What Is HMRC and Why Does It Matter?

The UK equivalent of the IRS is His Majesty’s Revenue & Customs (HMRC). HMRC is responsible for collecting taxes, enforcing regulations such as the national minimum wage, and distributing certain state benefits.

If you’re an American living in the UK, you may be required to file a UK Self-Assessment Tax Return with HMRC in addition to your US return.

Here’s How Greenback Simplifies the Process:

One Upload, Shared Access

Upload your documents once through your Greenback Tax Companion Account. Your US and UK accountants—both working within the Greenback team—coordinate directly to ensure seamless collaboration and maximum efficiency.

In-House UK Expertise

Greenback has partnered with a UK Chartered Accountant who specializes in helping American expats file UK taxes. This allows for:

• Time savings: No need to send files or explain your situation twice
• Tax savings: Our collaborative approach ensures no opportunity is missed
• Expert advice: Access personalized support and recommendations

You can start your UK onboarding while your US return is still in progress, but your UK tax return can only be finalized once the US return is complete, as the two often rely on shared figures.
