Questions

Do I need an accountant to use NVC Comply?

No. NVC Comply is built for directors who want to file themselves. Every number is explained in plain English before you submit. You review and approve; we handle the maths and the filing.

What counts as a free period?

Your first accounting period is free regardless of length. You can import transactions, generate your CT600, and file to HMRC at no cost. Your subscription starts when you begin your second period.

Is this HMRC-recognised software?

Yes. We file CT600 returns directly via the HMRC API using the MTD (Making Tax Digital) gateway. Your submission reference comes back instantly.

Can I use this if CATO was my previous tool?

Yes. NVC Comply is a direct replacement for the HMRC CATO portal, which closed on 31 March 2026. The workflow is similar: import or enter transactions, review, file.

What if my company has more complex tax affairs?

NVC Comply handles the vast majority of single-director limited companies: salary, dividends, business expenses, capital equipment, director loans, and marginal relief. If you have R&D tax credits, group relief, or controlled foreign companies, you will need specialist software.

Can I cancel at any time?

Yes. Monthly plans cancel at the end of the billing month. Annual plans cancel at the end of the year. No pro-rata refunds on annual commitments.

File your first period free

No card. No commitment. Your CT600 filed or it costs nothing.
