If you’re a Lincoln sole trader and you’ve spotted the words Making Tax Digital on an HMRC letter, you’re not alone. The rules change in April 2026, and many self-employed people across Lincolnshire are unsure what to do next.

This guide explains what making tax digital Lincoln rules mean for you. You’ll learn the deadlines, the software you need, the real costs involved, and how to get ready without losing weekends to admin.

What Is Making Tax Digital for Income Tax?

Making Tax Digital for Income Tax is an HMRC scheme that requires sole traders and landlords to keep digital records and submit tax updates quarterly using approved software. It replaces the annual Self Assessment return for those above the income threshold.

HMRC introduced the scheme to close the tax gap and modernise record keeping. It’s part of a wider digital tax programme that already covers VAT.

The shift in plain terms: instead of one tax return a year, you’ll send six digital submissions. That’s four quarterly updates, one End of Period Statement, and one Final Declaration. It’s a significant change from the current Self Assessment process.

When Does MTD for Income Tax Start for Sole Traders?

Making Tax Digital for Income Tax becomes mandatory from 6 April 2026 for sole traders and landlords with gross income above £50,000. The threshold then drops in stages over the following two years.

Start Date	Income Threshold	Who’s Affected
6 April 2026	Above £50,000	Sole traders and landlords
6 April 2027	Above £30,000	Sole traders and landlords
6 April 2028	Above £20,000	Sole traders and landlords

How HMRC measures the threshold: it’s based on your gross self-employment and property income, not your profit. HMRC checks your most recent Self Assessment return to decide if you’re in scope.

If your income fluctuates above and below the threshold, you stay in MTD once you’ve joined. HMRC has confirmed a three-year rule for falling below the limit.

Keep an eye on our key tax dates and deadlines page so you know exactly when each quarterly submission is due.

What Lincoln Sole Traders Need to Do Differently

You’ll need to change how you record income and expenses and how often you talk to HMRC. The four core obligations are simple to state but they change your routine.

1. Keep digital records of every business transaction using compatible software.
2. Submit a quarterly update to HMRC within one month of each quarter end.
3. Submit an End of Period Statement after the tax year closes.
4. Submit a Final Declaration replacing your current Self Assessment return.

For Lincoln tradespeople, this means logging materials and labour on the day, not at year end. If daily bookkeeping already feels like a stretch, MTD will sharpen that pressure.

For agricultural contractors across Lincolnshire, diesel receipts and mileage need a digital home. Freelance designers and consultants serving Lincoln businesses face the same shift, with client invoices and software subscriptions tracked in real time.

What Software Is MTD Compatible?

MTD compatible software is any HMRC recognised tool that can record digital tax data and submit it directly to HMRC. There is no free HMRC software for MTD for Income Tax, unlike MTD for VAT.

The main options for sole traders are:

• Xero (strong all-rounder, especially for cloud-first businesses, and we offer face-to-face Xero training to get you confident on it)
• QuickBooks (popular with sole traders and tradespeople)
• FreeAgent (often free with NatWest, Royal Bank of Scotland, and Mettle accounts)
• Sage Accounting (established option for established businesses)
• Spreadsheets plus bridging software (possible but more work)

You can check the full list on the HMRC recognised software page. Always confirm a tool is approved before paying for a subscription.

Can I Still Use Spreadsheets Under MTD?

Yes, spreadsheets are still allowed under MTD for Income Tax. You’ll need bridging software to send the data to HMRC in the right digital format, and the spreadsheet itself must contain all required records.

In practice, most sole traders find dedicated accounting software simpler. Bridging tools add a step every quarter and one broken formula can hold up your submission.

The Real Cost of MTD: Time, Money, and Penalties

The cash cost of MTD is modest. The time cost and penalty risk are where most sole traders feel the squeeze.

Software costs typically run from £10 to £30 per month for a sole trader plan. That’s £120 to £360 a year before any add-ons.

Time costs vary by setup. A self-managing sole trader should expect three to six hours per quarter on bookkeeping and submissions if they’re starting from paper records.

Approach	Doing It Yourself	With a Cloud Accountant
Time per quarter	3 to 6 hours	Under 1 hour
Monthly cost	£10 to £30 software only	Software plus fixed monthly fee
Penalty risk	Higher if deadlines slip	Low, deadlines managed
Software setup	You research and configure	Included and tailored

Penalties matter. HMRC uses a points based system. You get one point per missed deadline. Hit four points as a quarterly filer and you trigger a £200 fine. Each further miss adds another £200.

Late payment penalties and interest stack on top. The ICAEW MTD guidance sets this out in full for anyone who wants the detail.

How to Prepare for MTD: A Step-by-Step Checklist

Use these six steps to get MTD ready before April 2026. The earlier you start, the smoother the transition.

1. Check whether your gross income from self-employment and property crosses £50,000.
2. Choose MTD compatible software that suits your trade and bank setup.
3. Set up digital record keeping with bank feeds, receipt capture, and a mileage app.
4. Register for MTD for Income Tax through your software or your accountant.
5. Add the four quarterly submission dates to your diary for the year ahead.
6. Decide whether to self manage or bring in a Lincoln friendly cloud accountant.

When we moved a self-employed surveyor to Xero last year, her first quarterly submission took just under three hours. By the second cycle she was through it in 45 minutes.

Not at first. Sole traders earning under £50,000 don’t have to join MTD for Income Tax in April 2026. The threshold drops to £30,000 in April 2027 and £20,000 in April 2028. You can sign up voluntarily earlier if you want to transition gradually.

What software is MTD compatible for sole traders?

HMRC publishes an official list of recognised MTD compatible software. Common options for sole traders include Xero, QuickBooks, FreeAgent, and Sage. Spreadsheets work only with bridging software that submits data to HMRC in the required format. There is no free HMRC software for MTD for Income Tax.

How often do I need to submit under MTD?

You’ll submit four quarterly updates to HMRC each year, plus an End of Period Statement and a Final Declaration after the tax year ends. That’s six digital submissions per year in total. It replaces the single annual Self Assessment return most sole traders are used to.

What happens if I miss an MTD deadline?

HMRC uses a points based penalty system. You get one point for each missed deadline, and once you reach four points as a quarterly filer, a £200 fine is triggered. Further missed deadlines add further £200 penalties. Late payment also attracts interest and separate late payment penalties.
