MTD Income Tax: Free Quarterly Filing for Sole Traders

If you’re a UK solopreneur earning decent money, April 2026 isn’t “just another HMRC change”. It’s a workflow change.

Making Tax Digital for Income Tax Self Assessment (MTD ITSA) shifts many sole traders and landlords from one annual Self Assessment submission to digital record-keeping plus quarterly updates. The admin load doesn’t merely increase—it spreads across the entire year. And for one-person businesses, admin creep is one of the fastest ways to lose momentum on sales, marketing, and delivery.

There is some good news: ANNA Money says it will provide free MTD ITSA quarterly filings permanently for sole traders and landlords in scope, and it’s bundling that into its app-based business account. Free is nice, but the bigger win is what this signals for solopreneur growth: automation isn’t optional anymore; it’s part of staying compliant without sacrificing billable hours.

What’s changing with MTD ITSA (and who it hits first)

MTD ITSA requires digital records and quarterly updates to HMRC, replacing the once-a-year rhythm many self-employed people are used to.

From the current timetable:

• From April 2026: sole traders and landlords with qualifying income over £50,000 must comply.
• From April 2027: the threshold expands to qualifying income over £30,000.

The real shift: from “tax season” to year-round reporting

The biggest mental change is this: your tax admin becomes a monthly/weekly habit instead of a January panic. Quarterly submissions don’t necessarily mean paying tax four times a year in the same way, but they do mean keeping your records in order continuously and sending regular updates.

For UK solopreneurs, this matters because it directly competes with the activities that drive growth:

• writing content
• following up leads
• sending proposals
• doing client work
• building referral relationships

If your “system” is a spreadsheet plus a shoebox of receipts (physical or digital), quarterly reporting will feel like HMRC has added three extra mini-deadlines to your calendar.

Why spreadsheets become a trap under MTD

Spreadsheets aren’t evil. They’re just fragile.

Most spreadsheet-based bookkeeping falls apart when:

• you miss a week and forget what a payment was for
• you can’t match bank transactions cleanly
• you don’t categorise expenses consistently
• you store receipts in three different places
• VAT/tax rules or categories change and your sheet doesn’t

Quarterly reporting amplifies those cracks. What used to be “I’ll fix it later” becomes “I need it accurate enough to submit”.

ANNA Money’s free MTD ITSA filings: what it actually means

ANNA Money has announced free MTD ITSA quarterly filings on a permanent basis for sole traders and landlords, positioning it as “no strings attached”. It also says customers get their full MTD Self Assessment (including final return) and Auto Accountant free in the first year.

ANNA’s logic is simple: instead of charging an extra subscription for MTD features (common in accounting software), it bundles submissions into its business account and tax app.

“For freelancers and contractors, MTD ITSA means moving from filing once a year to managing tax all year round. That’s a big change… By offering free MTD filings forever, we’re trying to remove cost as a barrier.”

That quote (from ANNA Money’s co-founder and co-CEO, Boris Diakonov) gets to the point: the admin is rising, and many people will try to delay spending on tools. Free removes one objection, but you still need a workable process.

The bigger issue isn’t the filing—it’s the plumbing

Most solopreneurs focus on the submission itself.

I think that’s backwards.

The submission is the easy part. The hard part is clean data. If you don’t capture invoices, expenses, mileage, and categories consistently, your “free filing” becomes a quarterly scramble.

So treat free MTD filing as a trigger to build a lightweight finance system:

• separate business spending from personal spending
• capture receipts at the point of purchase
• reconcile weekly (15 minutes beats 5 hours)
• maintain simple categories you can stick to

That’s how you keep compliance from stealing your marketing time.

A practical MTD setup for one-person businesses (keep it boring)

A boring system is a scalable system. Your goal is not perfect bookkeeping. Your goal is repeatable admin that doesn’t derail growth.

Here’s a simple setup that works for most UK solopreneurs moving into MTD ITSA.

Step 1: Put everything through one business account

Start with separation. If business income and costs are mixed with personal spending, every quarter becomes detective work.

Minimum standard:

• client payments go into the business account
• subscriptions, software, travel, and equipment come out of the business account
• keep personal spending out of it as much as possible

This isn’t just tidy—it’s how you make automation possible.

Step 2: Choose one “source of truth” for transactions

You’ll typically pick either:

• an accounting tool that connects to your bank, or
• a banking app that includes accounting/tax features

The point is consistency. If you record sales in one place, expenses in another, and receipts in a third, you haven’t built a system—you’ve built a pile.

Step 3: Weekly “money minute” routine (15–20 minutes)

Quarterly reporting is manageable if you keep up with the week.

Put a recurring slot in your calendar (Friday afternoon is popular for a reason) and do:

1. Match transactions to invoices/receipts
2. Categorise anything uncategorised
3. Flag anything unclear while you still remember it
4. Check you’re setting aside enough for tax

A weekly rhythm is the easiest form of solopreneur automation: it prevents backlog.

Step 4: Keep quarterly submissions boring and predictable

By the time a quarterly deadline arrives, you want it to feel like pressing “send”, not rebuilding your books.

If you’re aiming for business growth, treat quarterly MTD updates like you treat content scheduling: batch the work, standardise the process, and remove decision fatigue.

Cost control: free tools help, but time is still the real price

ANNA’s free MTD ITSA filings are timely, especially with living costs and business overheads still squeezing freelancers. But even if the filing costs £0, there are still two “hidden bills”:

1. Time cost: chasing transactions, re-doing categories, finding receipts
2. Attention cost: breaking your flow every quarter, worrying about errors

Solopreneur growth depends on protecting deep work time—client delivery, marketing, and product creation.

So here’s a strong stance: paying for the right system is often cheaper than “free” plus chaos.

That said, if a provider genuinely offers free submissions and it fits your workflow, great. Just judge it on outcomes:

• Do you spend less time on admin each month?
• Are your records cleaner?
• Do you feel calmer approaching deadlines?

If the answer’s no, switch. Loyalty to tools is expensive.

Quick answers UK solopreneurs are asking about MTD ITSA

“Do I have to start in April 2026?”

If your qualifying income is over £50,000, you’re in the first wave scheduled from April 2026. Over £30,000 follows from April 2027.

“Does MTD mean I’ll pay tax quarterly?”

MTD ITSA introduces quarterly updates. How payments are handled can depend on HMRC rules and your situation. The key operational change is reporting more frequently and keeping digital records.

“Can I keep using spreadsheets?”

Some people will try. The problem is that quarterly reporting punishes messy data. If you’re determined to use spreadsheets, you’ll need strict habits around receipt capture and bank reconciliation—and many people simply won’t keep that up.

“What should I do this month to prepare?”

Pick one action that reduces future pain:

• open or tidy up a dedicated business account
• move recurring business subscriptions to that account
• start weekly reconciliation
• test an MTD-capable tool before deadlines hit

Preparation beats heroics.

The growth angle: MTD is forcing better operations (use that)

Most companies get this wrong: they treat HMRC changes as an annoying compliance project. Smart solopreneurs treat them as a reason to upgrade operations.

MTD ITSA pushes you toward:

• cleaner financial visibility (you’ll spot expensive months sooner)
• more accurate tax provisioning (fewer nasty surprises)
• better decision-making (you’ll know what you can afford)

And that ties directly into the UK Solopreneur Business Growth theme: the same automation mindset that makes your marketing consistent can make your admin consistent.

If you can systemise lead capture and content scheduling, you can systemise bookkeeping. It’s the same muscle.

Your next steps before April 2026

If you’re in the April 2026 group, don’t wait for “later in the year”. The easiest time to set this up is before you’re forced to.

Use this simple plan:

1. Confirm if you’re in scope (qualifying income threshold)
2. Choose your tool stack (banking + bookkeeping + submission)
3. Build a weekly routine that keeps records current
4. Do a test quarter: run your internal “quarterly close” even if you’re not filing yet

The goal is confidence. You want MTD to feel like admin you can handle, not a threat to your time.

If free MTD quarterly filing (like ANNA’s offer) reduces the cost barrier for you, take advantage—then put the saved money into the growth activities that compound: content, partnerships, and lead generation.

What’s your plan for quarterly reporting: a proper system, or another year of hoping January-you can fix it?
