The Real Cost of Making Tax Digital: What Sole Traders Will Actually Pay
This is Money reported this week that MTD will cost the self-employed a collective £2 billion. That headline is designed to terrify you. Let's look at what it actually means for your wallet — because the individual costs are far more manageable than the aggregate number suggests.
Cost Overview: The Real Numbers
Here's the honest breakdown of what MTD will cost a typical sole trader each year:
| Cost Category | DIY (Cheapest) | DIY (Comfortable) | With Accountant |
|---|---|---|---|
| MTD software | £0 | £120-180/year | Often included in accountant fee |
| Accountant/bookkeeper | £0 | £0 | £300-800/year extra |
| Your time (opportunity cost) | ~8 hours/year | ~4 hours/year | ~1 hour/year |
| One-off setup | 2-4 hours | 1-2 hours | Handled by accountant |
| Total annual cost | £0 | £120-180 | £300-800 extra |
| After tax relief (40%) | £0 | £72-108 | £180-480 extra |
For most sole traders doing their own books, the real cost is somewhere between £0 and £15/month for software, plus a few hours of your time per year. That's it.
Software Costs: Free to £35/Month
MTD-compatible software is the main new expense. Here's what the market looks like:
Free Options
| Software | Cost | What You Get | Limitations |
|---|---|---|---|
| HMRC MTD software | Free | Basic digital record keeping + quarterly submissions | Very basic features, no invoicing, no bank feeds |
| Some bridging software | Free or pay-per-submission | Submit from existing spreadsheets | Typically £5-15 per submission (£20-60/year) |
Budget Options (£10-15/month)
| Software | Monthly Cost | Annual Cost | What You Get |
|---|---|---|---|
| QuickBooks Simple Start | £12 | £144 | Invoicing, expense tracking, bank feeds, MTD submissions, basic reports |
| Xero Starter | £15 | £180 | Similar to QuickBooks, clean interface, good mobile app |
| FreeAgent (via NatWest/Mettle) | £0-14.50 | £0-174 | Full accounting, invoicing, tax estimates. Free with some business bank accounts. |
Full-Featured Options (£20-35/month)
| Software | Monthly Cost | Annual Cost | Best For |

💡 Pro tip: Free FreeAgent via NatWest/Mettle

Accountant Costs: What Changes
If you already use an accountant, MTD will likely increase your fees. Here's what we're hearing from the profession:
If You Already Have an Accountant
| What Changes | Estimated Extra Cost |
|---|---|
| Quarterly submissions (if accountant does them) | £100-300/year (4 × £25-75 per submission) |
| End of Period Statement review | £50-150 |
| MTD setup and software training | £100-200 (one-off) |
| Software licence (if included in their service) | Often bundled |
| Total extra annual cost | £150-450/year |
Some accountants are absorbing the extra MTD work into existing fees; others are pricing it separately. Ask yours what their plan is before April.
If You Don't Currently Have an Accountant
You don't need one for MTD. If you currently handle your own Self Assessment, you can handle MTD yourself. The quarterly submissions are simpler than a full tax return.
However, if MTD feels overwhelming and you'd rather hand it off, expect to pay:
- Basic bookkeeping + MTD submissions: £400-800/year for a simple sole trader
- Full service (bookkeeping + MTD + Self Assessment): £600-1,200/year
The Time Cost Nobody Mentions
The monetary cost is only half the story. Here's the time investment:
One-Off Setup (First Time Only)
| Task | Estimated Time |
|---|---|
| Choosing and signing up for software | 1-2 hours |
| Setting up your business in the software | 30-60 minutes |
| Connecting your bank account | 15 minutes |
| Entering opening balances | 15-30 minutes |
| Signing up for MTD via Government Gateway | 15-30 minutes |
| Total one-off setup | 2-4 hours |
Ongoing Quarterly (Per Quarter)
| Task | If Using Software Regularly | If Catching Up at Quarter-End |
|---|---|---|
| Reviewing transactions | 10-15 minutes | 1-2 hours |
| Categorising any uncategorised expenses | 5 minutes | 30-60 minutes |
| Submitting the quarterly update | 5 minutes | 5 minutes |
| Total per quarter | 20-25 minutes | 1.5-3 hours |
The lesson: keep your records up to date during the quarter and the submission takes 20 minutes. Leave it all to the last minute and it takes 3 hours. This is true with or without MTD — but MTD forces the discipline of quarterly reconciliation, which most accountants would say is a good habit anyway.
One-Off Setup Costs
Beyond software, there may be some initial costs:
| Item | Cost | Do You Need It? |
|---|---|---|
| MTD software subscription | £0-35/month | Yes (mandatory) |
| Accountant setup fee | £100-200 | Only if using an accountant |
| Training/learning | £0 (free YouTube tutorials) | Helpful but not essential |
| New computer/tablet | £0 (use existing device) | No — any modern device works |
| Receipt scanner app | £0 (free apps available) | Useful but not required |
Total one-off cost for most people: £0. The software subscription is the only real cost, and that's ongoing, not one-off.
4 Ways to Comply for Under £200/Year
Option 1: HMRC's Free MTD Software — £0/year
HMRC is providing basic MTD-compatible software for free. It handles digital record-keeping and quarterly submissions. Limitations: very basic, no invoicing, no bank feeds, no expense categorisation.
Best for: Very simple businesses with few transactions who just want to tick the compliance box.
Option 2: Free FreeAgent via NatWest/Mettle — £0/year
Open a free Mettle business account (NatWest's digital offering) and get FreeAgent — a full-featured accounting platform — completely free. This is the best value option currently available.
Best for: Anyone willing to switch or add a business bank account for the free software benefit.
Option 3: Budget Software — £120-180/year
QuickBooks Simple Start (£144/year) or Xero Starter (£180/year) give you everything you need: bank feeds, expense tracking, invoicing, and MTD submissions.
Best for: Sole traders who want good software without the bank account requirement.
Option 4: Bridging Software — £20-60/year
If you love your spreadsheet and refuse to give it up, bridging software connects your spreadsheet data to HMRC for quarterly submissions. You still need to keep digital records, but the software acts as the bridge.
Best for: People who are very comfortable with spreadsheets and have simple affairs.

Good News: It's All Tax-Deductible
Every penny you spend on MTD compliance is a legitimate business expense:
- Software subscriptions ✅
- Accountant fees ✅
- Training courses ✅
- Any hardware purchased specifically for business use ✅
This means the actual cost is reduced by your marginal tax rate:
| You Pay | Tax Rate | Real Cost After Relief |
|---|---|---|
| £180/year (software) | 20% (basic rate) | £144/year |
| £180/year (software) | 40% (higher rate) | £108/year |
| £500/year (software + accountant) | 20% (basic rate) | £400/year |
| £500/year (software + accountant) | 40% (higher rate) | £300/year |
If you're earning over £50,000 (which you must be to be in the first MTD wave), you're likely a higher-rate taxpayer. That means 40% of your software cost is effectively covered by tax relief.
Cost Comparison: 4 Different Approaches
Here's what a typical sole trader earning £60,000 would pay under each approach:
| Approach | Software | Accountant | Time/Year | Total Cost | After Tax Relief |
|---|---|---|---|---|---|
| Free DIY | £0 | £0 | 8-12 hours | £0 | £0 |
| Budget DIY | £144-180 | £0 | 4-8 hours | £144-180 | £86-108 |
| Full DIY | £174-360 | £0 | 4-6 hours | £174-360 | £104-216 |
| Accountant-managed | £0 (included) | £300-800 | 1-2 hours | £300-800 | £180-480 |
For context, that £60,000 earner pays roughly £12,500 in income tax and £5,000 in National Insurance. The MTD compliance cost is 0-4% of their tax bill. It's an annoyance, not a financial catastrophe.
What to Choose Based on Your Situation
📋 Simple sole trader, few transactions per month
Use HMRC's free software or get FreeAgent free via Mettle. Total cost: £0.
📊 Active sole trader, 20+ transactions per month
Use QuickBooks Simple Start (£12/month) or Xero Starter (£15/month). The bank feeds and categorisation will save you time. Total cost: £144-180/year (£86-108 after tax relief).
🏠 Landlord with rental properties
Consider Hammock (free-£10/month, specifically for landlords) or FreeAgent. For more, see our MTD for Landlords guide.
📈 Growing business, multiple income streams
Invest in FreeAgent (£14.50-36/month) or Xero Growing (£30/month). The features justify the cost at your income level.
🤷 "I don't want to think about it"
Get an accountant to handle everything. Expect £300-800/year extra. Worth it if your time is better spent earning.
Get Ready for MTD Without the Guesswork
Our MTD Readiness Toolkit includes a full software comparison table, 30-day setup checklist, quarterly deadline calendar, and step-by-step setup guides for the top 5 MTD software options. Everything you need to get compliant — for less than one month of most software subscriptions.
The Bottom Line
The headline number of £2 billion is real, but misleading at the individual level. For most sole traders, MTD will cost somewhere between £0 and £15 per month in software, plus a few hours of your time per year. If you're already using accounting software, the marginal cost is essentially zero.
The biggest cost isn't financial — it's the initial learning curve and setup time. But that's a one-off investment that pays for itself through better record-keeping, fewer missed expenses, and no more January panic.
Start with the cheapest option that meets your needs, and upgrade if you find you need more features. You can always switch software later.
