Most returns need the same papers every year. Send what you have; we ask once for anything missing.
Not always. If your income is wages and savings only, filing yourself may be enough, and we will say so in the first meeting.
Every piece of work has a fixed fee in a written quote, agreed before we start. If the work changes, we tell you and agree the difference first.
Come and see us as soon as you can. We prepare late returns and explain what usually happens next; how the tax office responds is up to the tax office.
Yes. With your written authorisation we can speak to the tax office about your file and reply to its letters.
Yes. First meetings work well by video, and records can be sent through a secure upload link.
At least as long as the tax office can review the return. We suggest seven years for most papers; ask us about your own case.
