About thirty plain questions: rent in, expenses out, mortgage interest. The CT600, tax computation and FRS 105 accounts filed direct to HMRC, the Companies House step sorted, and every deadline your company has on one timeline. £10 for a dormant company. No VAT is added, and the price never goes up. Pay only when you file.
Every year a buy-to-let limited company owes HMRC a Company Tax Return (the CT600, FRS 105 accounts and a tax computation), owes Companies House its accounts and a confirmation statement, and owes the tax itself, on a date that lands before either filing. FileMyRent does the filings from your answers and puts every date on one timeline.
We pull its details, deadlines and last accounts from Companies House. Half the form fills itself.
Rent, expenses, mortgage interest. About thirty of them; the tax builds live as you type.

We file the Company Tax Return for UK buy-to-let companies: SPVs, family property companies, accidental landlords with a single flat. A few rare situations need an accountant instead of software. Tick any that happened this year, or just start:
Not sure? Just start. We check everything as you go and tell you in plain English if something doesn't fit.
