Can my company claim the whole mortgage payment?

Not all of it. The interest is usually a cost the company may be able to claim, but the part paying off the loan isn’t; it just reduces what’s owed. Your lender’s yearly statement shows the split. We sort every payment and any remortgage fees. You check everything first.

A year-end example for accounts for a buy-to-let company with a mortgage

Your lender takes one monthly payment, but part of it is interest and part pays off the loan. We use your yearly mortgage statement to split it for you, so the accounts show the right figures.
