Spreadsheet alternativeSimple MTD software FAQs
Practical answers before you choose a system.
What is the simplest software for MTD?
The simplest option is the one you can keep using all year. CalCal is built around everyday income and expense records.
Do I need accounting experience?
No. CalCal is designed for people doing their own bookkeeping, with categories, reports, and tax workflows in plain language.
Can I start before MTD applies to me?
Yes. Starting early means your digital records are already in place when MTD deadlines begin.
Can I use CalCal for VAT MTD too?
Yes — VAT MTD sits on Unlimited+. Free does not include VAT submission.
Is MTD included in the free trial?
Yes for Income Tax MTD: during the 10-day Free trial you can connect to HMRC and submit an MTD Income Tax update if you’re due. VAT is not on Free. After 10 days, upgrade to Unlimited to keep filing.
Is this the same as tax-return-only?
No. One-off tax-return-only is for legacy Self Assessment (£35). MTD Income Tax is what you try on Free and keep with Unlimited.
Less accounting software, more getting on with it
Use MTD software you can actually keep up with.
The best MTD system is not the one with the most menus. It is the one that helps you stay organised before HMRC deadlines arrive.
Free includes Income Tax MTD connect and submit for 10 days. VAT needs Unlimited+. CalCal provides software, not personalised tax advice.
