Making Tax Digital Changes for Small Businesses

For many business owners, Making Tax Digital changes will feel less like a single deadline and more like a new way of managing tax records throughout the year. If you are a sole trader or landlord, the key question is no longer simply whether you file a Self Assessment return. It is whether your income means you must keep digital records and send updates to HMRC using compatible software.

The change is designed to make tax administration more current and less dependent on a last-minute annual return. Done well, it can give you a clearer view of income, costs and tax exposure. Done poorly, it can create avoidable pressure, duplicated work and rushed corrections. Preparation matters.

What the Making Tax Digital changes mean

Making Tax Digital for Income Tax Self Assessment, often shortened to MTD for ITSA, changes the reporting process for self-employed people and landlords with qualifying income above the relevant threshold. Qualifying income means your gross income from self-employment and property before expenses are deducted. It is not your profit, salary from employment, dividends or pension income.

Those required to join must maintain certain accounting records digitally and use compatible software to submit quarterly updates to HMRC. At the end of the tax year, they will complete a final declaration, confirming their overall tax position and including other relevant income or claims.

Quarterly updates are not intended to be four tax bills. They are periodic summaries of income and expenses. However, they do make the state of your records visible earlier, which is a strong reason to keep bookkeeping up to date rather than treating it as a January task.

Who needs to act and when

The rollout applies first to sole traders and landlords. From 6 April 2026, it applies where qualifying income was more than £50,000 in the 2024-25 tax year. From 6 April 2027, the threshold reduces to more than £30,000.

The Government has also set out plans to bring in people with qualifying income above £20,000 from April 2028. The detailed rules and practical arrangements can change, so it is sensible to review your position well before each start date rather than relying on old guidance.

If you have both rental and self-employment income, HMRC will look at the combined total. For example, a consultant earning £38,000 from freelance work and receiving £15,000 of gross rental income would have qualifying income of £53,000. Even if deductible expenses reduce their profit considerably, they may still be within the first phase of MTD for Income Tax.

Limited companies are different. A company director who receives income through a limited company is not brought into MTD for Income Tax solely because of the company’s turnover. The rules above concern individual self-employment and property income. Directors may still have personal Self Assessment obligations, and their company must continue to meet its existing filing and record-keeping requirements.

The practical changes to your record keeping

The core requirement is not simply owning an accounting app. Your records must be kept digitally, and the information must move between software and HMRC through a digital link. In practical terms, this usually means recording sales, income and expenses in compatible bookkeeping software, rather than maintaining figures in a paper ledger and typing totals into a return at year end.

For a tradesperson, that might mean capturing invoices, mileage and materials as transactions occur. For a landlord, it may mean keeping rent received, agent fees, repairs, insurance and finance-related costs clearly categorised for each property business. For a content creator, it can mean separating platform payouts, brand collaborations, affiliate income, equipment costs and business subscriptions from personal spending.

A spreadsheet may form part of the process in some circumstances, but it is not automatically enough on its own. The important point is that the full process meets HMRC’s digital record and submission requirements. Copying and pasting numbers between systems is unlikely to provide the reliable digital trail that MTD expects.

Quarterly updates need a routine, not a scramble

The most significant operational shift is the move to quarterly submissions. These updates follow standard periods, so the information needs to be ready at regular points in the year. The submission deadline is generally one month after the end of the relevant quarter.

That does not mean every transaction must be perfect on the day it happens. It does mean you need a dependable monthly routine: reconcile the bank account, review unpaid invoices, check expense categories, save supporting evidence and deal with anything unclear before the quarter closes.

Small errors are easier to correct when they are found quickly. A missing receipt from two weeks ago is usually straightforward. Trying to reconstruct twelve months of card payments, cash income and property costs in January is costly and stressful.

It is also worth setting expectations around estimates. Quarterly updates give HMRC a developing picture, but the final declaration remains the point at which you confirm the full year’s position. Certain year-end adjustments, reliefs and other personal tax details will be dealt with then. Good bookkeeping supports accurate updates, but it does not remove the need for informed year-end tax review.

Start with the figures HMRC will use

Before choosing software or changing your processes, identify your qualifying income using the correct tax year. Review your submitted 2024-25 Self Assessment return if you may be required to join from April 2026. If your income is close to the threshold, do not guess based on money currently in the bank or on your expected profit.

Then consider what the numbers mean for your business. A landlord with occasional repair costs may have high gross rents but modest taxable profit. A contractor may have fluctuating income and work through a company one year but as a sole trader the next. A creator’s income may rise quickly after a successful campaign. The requirement depends on the relevant income and business structure, not on whether the change feels proportionate to your workload.

If you are below the threshold, digital bookkeeping is still often worthwhile. It can make cash flow clearer, reduce the risk of missed expenses and give you a more orderly tax return process. But there is a difference between adopting useful tools voluntarily and being required to follow the MTD rules. Knowing which applies to you prevents unnecessary concern.

Choose software around your workflow

Compatible software should make your working life easier, not add another admin task. The right choice depends on how you receive money, how many transactions you process and whether you need to track VAT, payroll, stock, projects or rental properties.

For a low-volume sole trader, simple invoicing, receipt capture and bank feeds may be enough. An e-commerce operator will usually need stronger sales-channel and payment-provider integrations. A healthcare practice or care business may need clearer reporting across staff costs, suppliers and service lines. The best system is the one your business can use consistently and that produces records your accountant can review efficiently.

Bank feeds are particularly useful, but they are not a substitute for oversight. They can import transactions, yet they cannot always tell whether a purchase was wholly business-related, whether a payment is income or a loan, or whether a cost should be treated in a particular way for tax. Someone still needs to review the data with care.

Avoid the mistakes that create problems later

The biggest risk is waiting for HMRC to contact you before reviewing your records. By then, you may be trying to migrate incomplete data, learn new software and meet an approaching reporting date at the same time.

Keep business and personal spending separate wherever possible. Use a dedicated business bank account or card, retain invoices and receipts, and make a habit of explaining unusual payments. This is especially valuable for mixed-income businesses, such as a creator with both freelance services and online platform income, or a landlord who also runs a consultancy.

Do not assume that an accountant can simply fix everything at year end. Professional support is most effective when records are current and questions are raised early. An accountant can help assess whether MTD applies, set up sensible categories, review quarterly information and identify tax planning points, but clean source records remain the foundation.

Use the change to improve financial control

There is an administrative cost to Making Tax Digital, particularly during the first year. You may need to pay for software, change habits or train a team member. For businesses with straightforward records, the new routine can initially feel disproportionate.

The upside is that regular records can turn bookkeeping into useful management information. You can see whether sales are rising, whether costs are drifting, how much cash should be reserved for tax and whether a decision is affordable before you make it. That is valuable whether you run a dental practice, manage rental properties or earn from digital platforms.

AccountingIN helps clients put practical systems around their records, so tax compliance supports better decisions rather than becoming another recurring worry. The most useful next step is simple: review your qualifying income, assess how you currently keep records and make the move before urgency takes over. A calm, consistent bookkeeping routine will serve your business long after the first MTD deadline has passed.
