FAQ
Frequently asked questions
How Flare handles US state and federal tax for startups.
Filings
State and federal returns for US companies, plus foreign subsidiary forms 5471 and 5472 where you have overseas entities. Additional support is available for more complex structures.
It is the cleanest path — the tax team works from books we already close. We can also pick up tax on ledgers we take over, after a historic review.
Working with Flare
In-house. Flare's tax team prepares and files your returns rather than handing them to an external preparer who does not know the company.
Yes. We file US and UK returns in-house, and work with trusted local partners for other jurisdictions, using consolidated books we already maintain.
