qwartly - MTD Bridging Software That Lets You Keep Your Spreadsheet

qwartly is MTD bridging software that connects your existing spreadsheets to Making Tax Digital. No new software to learn, no data to re-enter. Just £49/year.

Making Tax Digital for Income Tax Starts April 2026

From April 2026, HMRC requires sole traders and landlords with income over £50,000 to keep digital records and submit quarterly updates using MTD-compatible software. The threshold drops to £30,000 from April 2027 and £20,000 from April 2028.

How It Works

  1. Upload your spreadsheet - Drop in the same Excel or CSV file you already use.
  2. Map your columns - Tell qwartly which columns are income, expenses, and dates.
  3. Submit to HMRC - We format everything to HMRC's spec and submit via their official API.

MTD Bridging Software Pricing

£49 per year - Unlimited quarterly submissions, all spreadsheet formats, direct HMRC API connection, column mapping saved for next time, submission history and confirmations, email support.

That's less than £1 per week. Most MTD software charges £12-£30 per month.
