Making Tax Digital requires UK sole traders to submit quarterly income and expense updates digitally to HMRC. Bridging software acts as the transmission layer between your existing spreadsheet records and HMRC's API. It's an officially recognised submission method.
No. You keep recording income and expenses exactly as you do now. Cuppa just handles the final HMRC submission step. Upload your spreadsheet, map the columns once, and submit.
The MTD ITSA system is cumulative. Each quarterly submission must include all income and expenses from 6 April through the period end date, not just the current quarter. A Q3 submission should include 9 months of data. The wizard makes this clear at every step.
Yes. Your HMRC access token is stored server-side and never exposed to the browser. Submissions go directly from Cuppa's servers to HMRC with the full set of mandated fraud prevention headers. Your spreadsheet is processed in memory and not stored.
Yes. If your expected annual turnover is £90,000 or above, HMRC requires itemised expenses across 15 categories rather than a single consolidated total. The wizard handles both paths and asks you to declare your expected annual turnover upfront.
Your account, HMRC connection, and submission history all carry over. You can switch modes at any time in settings. Bridging submissions appear in your history with a Bridging tag.
