Why Now Is the Smartest Time to Organise Your Self Assessment 2025/26  as a Sole Trader

The 2025/26 UK tax year began on 6 April 2025, and ended on 5th April 2026. Now is the smartest time for Sole Traders to organise their Self Assessment and prepare for Making Tax Digital. 

For many sole traders, January feels far away. It is easy to assume Self Assessment can wait.

But the smartest business owners use April as their preparation window

Starting early changes everything. It turns Self Assessment from a stressful deadline into a structured process.

And with Making Tax Digital for Income Tax starting in April 2026 preparation matters more than ever.

If you missed our overview of how Making Tax Digital works, you can read it here:

Making Tax Digital for Income Tax UK, What It Is and Who It Applies To

Why the Start of the Tax Year Matters?

When the tax year resets, your records reset with it.

This gives you:

• A clean slate
• Clear financial visibility
• Time to improve systems
• Space to implement digital processes

Waiting until autumn removes that advantage. Waiting until January creates pressure.

Self Assessment works best when it runs quietly in the background all year.

How Making Tax Digital Changes Self Assessment

Self Assessment is no longer just one annual submission.

Making Tax Digital for Income Tax will require:

• Quarterly updates to HMRC
• Digital record keeping
• End of Period Statements
• A final declaration

That means more regular compliance.

If your Bookkeeping is inconsistent, quarterly submissions will feel overwhelming.

If your systems are structured from April, they become manageable.

The 2025/26 Advantage

Many sole traders are unsure whether they will meet the income threshold for Making Tax Digital.

The best approach is not to guess.

It is to review your position early.

When we prepare Self Assessment for our clients, we carry out a Making Tax Digital review alongside it. That way, you know:

• Whether you are likely to fall within scope
• What changes may be needed
• How your bookkeeping should be structured
• What quarterly reporting could look like

Clarity removes fear.

Preparation removes stress.

Why Sole Traders Leave It Too Late

January panic is rarely about tax itself.

It is usually about:

• Incomplete bookkeeping
• Missing receipts
• Uncertainty about profits
• Not knowing what HMRC expects

Those problems do not start in January.

They start in April when systems are not put in place.
