Common questions
Where do I find my payment reference?
Start with the current HMRC bill, your online account or the payment instructions we have sent you. The correct reference depends on the tax and sometimes the period being paid. If you are unsure, ask us before paying rather than reusing a reference from an old payment.
How do I send documents to Greystone?
Use the client portal or the agreed method we have arranged with you. If you cannot sign in, contact us so we can help.
Should I make a Companies House change myself?
If we handle your company filings, check with us first so we can coordinate the change and keep your records consistent.
What if the guidance does not answer my question?
Get in touch by email or phone. We welcome questions. Where your query needs detailed calculations, research or other additional work, we will discuss the scope and any fees with you beforehand.
