Your personal tax,
done right.
If you're a director, a shareholder, or earning income from multiple sources, your personal tax return is more complex than most. Runway makes sure it's accurate, filed well ahead of the deadline, and part of a bigger picture — not an afterthought at the end of January.
Self assessment tax returns for UK directors and founders
As a company director, you're almost certainly required to file a self assessment tax return. Between dividends, salary, benefits in kind, and potentially rental income or capital gains, your tax position is far more nuanced than a standard PAYE employee's.
Runway prepares and files your self assessment as part of a joined-up approach to your finances. We gather the information, calculate what's owed, claim every relief you're entitled to, and file with HMRC — well before the January deadline.
