For UK sole traders filing Self Assessment
Most sole traders either underclaim to stay safe, or overclaim and invite questions. This shows you how to get it right

Stop overpaying tax, without drifting into risky claims.

A practical, HMRC-referenced system to claim properly and stay out of trouble.

MyBaseline is a decision guide for sole trader expenses. It shows what is safe, what needs evidence, and what to avoid, using a clear green, amber, red structure.

Most sole traders stay ultra cautious and overpay. A few push too far and attract questions. MyBaseline helps you land in the sensible middle: claim what you are entitled to, and keep it defensible.

MyBaseline: Save Tax & Claim Maximum Expenses - Book Cover

Why this exists: HMRC guidance is fragmented and not written for real-world use. Most sole traders file without an accountant. Even when you do pay for help, you often get cautious filing based on what you surface and evidence. MyBaseline turns the rules into a simple decision system so you can claim properly and stay defensible.

Andrew Clifforth. Self-employed for 20+ years. Built for people who want clarity, not clever tricks.

Based on HMRC guidance, translated into the same green / amber / red logic professionals use internally. Designed for defensibility and clean records, not bravado.

✓ HMRC referenced ✓ Instant access ✓ One-off purchase ✓ No subscription ✓ Built for Self Assessment

Intro price ends 31 January. That's when your filing decisions become fixed. What you don’t claim by then is likely gone.

6 April is the start of the new tax year. Set this up once and run it properly all year, rather than patching things in January.

The cost of doing nothing: staying too cautious quietly costs money every year. Pushing too far creates awkward questions.

What You Get

Instant access to the complete MyBaseline system as a downloadable PDF. Practical, plain English, and designed to be used, not admired.


Most buyers use this to confirm they’ve repeatedly failed to claim for legitimate items - not to invent new ones.

Outcome: you move from “playing it ultra safe” to claiming legitimate expenses confidently, without straying into inspection trigger territory.

Common Questions

Is this actually safe and legal?
It is built around HMRC guidance and defensibility. It shows what is safe, what needs evidence, and what to leave alone. This is not tax avoidance.
I do not use an accountant. Is this for me?
Yes. In practice, most sole traders file without an accountant. MyBaseline is written for people who want to do it properly, without guessing and without drama.
If I do use an accountant, why would I still need this?
Because accountants file what you surface and evidence. If your inputs are vague, the outcome will be cautious. MyBaseline helps you hand over clean, defensible categories instead of a pile of “maybe”.
What about the “claim your meals out, holidays, Christmas presents” stuff on Instagram?
Ignore it. You cannot claim personal spending just because someone posts confidently online. MyBaseline keeps you within the rules and able to show your working.
How long does it take to apply?
Minimum effective use is simple: scan the categories and confirm you did not miss legitimate claims you already paid for. The smarter option is to run it through the year.

Why This Works When “Advice” Fails

It is decision-first. You are not reading for entertainment. You are deciding what to claim, what to evidence, and what to avoid.

Green / Amber / Red structure

It is defensibility-first. It is built to keep you within the rules and able to show your working, without overthinking.

HMRC-referenced, plain English

Stop overpaying. Claim properly. Stay defensible.

If you are still guessing, you are either leaving money behind or carrying risk you cannot explain. Fix the balance now.
