Found 8 potential mappings in your spreadsheet.
The only MTD software that reads your spreadsheet for you.
Every other bridging tool asks you to re-enter your data, reformat your spreadsheet, or switch to their templates. That defeats the entire point of "bridging." We built something different.
Upload. Done.
Drop any spreadsheet. Messy columns, weird headers, any format. Smart Map uses AI to scan your layout and map every field to the right HMRC category. No reformatting. No re-typing. Review the suggestions, hit submit, and your quarterly update is filed. Next quarter? One click, your mapping is saved.
Change how you work.
Download their template and link cells one by one with formulas. Or merge their worksheet into yours. Some offer clunky, dated Excel add-ins. HMRC rules mean you can't just re-key your figures, so every other tool forces you to adapt your spreadsheet to fit theirs. Different approaches, same problem: they all disrupt the workflow you already have.
"Smart Map is why MTD doesn't have to mean more work. It's the only AI in MTD bridging software, and it makes quarterly filing feel almost invisible."
Smart Map: the AI that no other MTD tool has.
Upload any spreadsheet. Smart Map scans your columns, understands your layout, and maps everything to HMRC fields automatically. No other bridging software does this.
Smart Map suggests. You decide. Nothing is submitted without your explicit approval.

Coming soonAny Excel spreadsheet
If it opens in Excel, it works with Abridged. We also provide optional templates if you want a starting point.
If HMRC won't penalise, why would we charge?
MTD for Income Tax is a legal requirement from April 2026, but HMRC's soft landing means no penalties for late quarterly submissions in year one. While HMRC aren't charging, neither are we.
Free until April 2027. Seriously.
We may introduce additional paid tiers after the soft landing period. Any paid features will always be optional, and we'll give a minimum of 6 months' notice of what, if any, charges there will be for quarterly returns for tax year 2027-28.

Charlotte Kieran
Founder
I spent years as an executive in the accounting software industry, at Sage, Exact, Albany (now Bottom Line), and NetSuite. I know how this market works and how vendors think. Then I stepped away to raise my family and pour time into things that matter: school governance, community, education.
But I'm also a landlord with a small property portfolio. When MTD was announced, I felt the same thing every accountant and landlord felt: frustration. I had a system that worked, a spreadsheet I'd used for years, and I resented being told to change it.
"I watched vendors treat accountants the way they always do. Price hikes, lock-in, pushing their own agenda. I come from a family of entrepreneurs. I know the burden this puts on small business owners who ultimately bear the cost."
So I started building something for myself. A way to keep my spreadsheet and still comply with MTD. The passion for technology that drove my career made it a logical challenge to solve, and once I saw it working, I knew it could help others too.
I worked with experienced developers to build Abridged into something genuinely different: bridging software that reads your spreadsheet, not the other way around. No templates, no re-entry, no lock-in. Just MTD, sorted.
Common questions
If yours isn't here, drop us a line at hello@abridged.tax
Making Tax Digital for Income Tax Self Assessment. From April 2026, sole traders and landlords earning over £50,000 must keep digital records and submit quarterly updates to HMRC. The threshold drops to £30,000 from April 2027.
No. That's the whole point. Upload whatever you've got, even if it's messy. Smart Map uses AI to read your spreadsheet and figure out what goes where. You review the mapping, make any tweaks, and submit.
Smart Map analyses the structure of your spreadsheet (column headers, layout, patterns) to match them to HMRC fields. It works even with inconsistent headers or unusual layouts.
Your actual financial figures are never sent to any AI model. Smart Map reads the labels, not the numbers. You always review and approve every mapping before anything is submitted. Smart Map is a suggestion engine. You have full control. Nothing goes to HMRC without your explicit sign-off.
We use Anthropic (Claude) and OpenAI under their zero data retention API policies. Neither provider stores, logs, or trains on any data sent through Abridged. Nothing is retained after processing.
Your choice. You can store it securely on AWS for your records, or have it deleted immediately after submission. Either way, we keep only the summary data that was sent to HMRC. Nothing more.
Year-end filing support is in active development and will be available soon. You won't need a separate platform. Quarterly and annual submissions will all be handled in Abridged.
MTD for Income Tax is a legal requirement from April 2026. You still need to keep digital records and submit quarterly updates. However, HMRC's soft landing means no penalty points for late quarterly submissions in year one (April 2026 to April 2027). It's time to get set up, not time to ignore it. Abridged is completely free during this period. If HMRC aren't penalising, we're not charging.
Not at all. Abridged works for anyone who needs to file under MTD ITSA: sole traders, landlords, and accountants managing clients. The multi-client dashboard is particularly useful for practices, but if you're filing for yourself it's just as simple.
We may introduce optional paid tiers at a later date. Any charges will always be optional, and we'll give a minimum of 6 months' notice of what, if any, fees will apply for quarterly returns for tax year 2027-28.
All data is encrypted at rest and in transit on AWS. We enforce two-factor authentication on all accounts and maintain a complete audit trail. You control whether spreadsheets are stored or deleted. We never share data with third parties, including AI providers.
