7 Common MTD Mistakes Self-Employed People in Gravesend Should Avoid

Making Tax Digital for Income Tax is a significant change, and whenever a new system is introduced, mistakes are inevitable. The good news is that many of the most common errors are entirely avoidable with a little awareness and preparation. At MCC Partners in Gravesend, we have been helping our self-employed clients get ready for MTD, and we have identified the pitfalls that are most likely to trip people up.

Here are seven mistakes to watch out for and how to avoid them.

Mistake 1: Assuming It Does Not Apply to You

Many sole traders assume that because their profit is below the threshold, they are not affected. But MTD thresholds are based on gross qualifying income, which is your turnover before expenses. A tradesperson in Gravesend with a turnover of £52,000 and expenses of £25,000 has a profit of £27,000, but their qualifying income of £52,000 puts them firmly in scope from April 2026. Always check your gross income, not your profit.

Mistake 2: Leaving Software Setup Until the Last Minute

Choosing and setting up MTD-compatible software takes time. You need to select the right platform, connect your bank accounts, configure your expense categories, and learn how the system works. Trying to do all of this in March 2026 while also running your business is a recipe for stress and errors. Start the process now and give yourself months to get comfortable.

Mistake 3: Not Keeping Records Up to Date

Under the annual Self Assessment system, many self-employed people would let their records build up and then sort everything out in one go before the January deadline. This approach simply does not work with quarterly reporting. If your records are not up to date, you cannot submit an accurate quarterly update. Build a habit of reviewing and categorising your transactions weekly, not quarterly.

Mistake 4: Forgetting About Multiple Income Sources

If you have both self-employment income and rental property income, you will need to submit separate quarterly updates for each source. That means eight quarterly submissions per year, not four. Many people do not realise this until they are already in the system. If you have multiple income streams, plan your workflow and software setup accordingly from the start.

Mistake 5: Confusing Quarterly Updates with Tax Returns

Quarterly updates are summaries of your income and expenses. They are not mini tax returns, and you do not need to calculate your tax liability or make complex accounting adjustments at each quarter. Some self-employed people over-complicate the process because they think each quarterly submission needs to be as detailed as a full tax return. Keep it simple: record your income and expenses accurately, and submit the summary. The detailed work comes at year end with your final declaration.

Mistake 6: Ignoring the Penalty Easement Conditions

HMRC has confirmed that penalty points will not be issued for late quarterly submissions in the first year for those joining in April 2026. However, some people interpret this as meaning they do not need to submit at all in the first year. That is not the case. You must still submit all four quarterly updates, and you must do so before you can file your final declaration. The easement simply means you will not get penalty points if those submissions are late. Treat the deadlines as real from day one.

Mistake 7: Trying to Do Everything Alone

MTD introduces a new way of working, and navigating it without professional support is risky. Your accountant can help with software selection, setup, ongoing record keeping advice, quarterly review, and the year-end final declaration. The cost of professional support is almost always less than the cost of mistakes, penalties, and missed tax-saving opportunities.
