How to Stop Treating Tax Season Like a Horror Movie

15 April 2026

January is the same every year. Someone calls because they haven't looked at their accounts since last April. The receipts are somewhere. The invoices might be in a folder, might not. The deadline's in two weeks.

It doesn't have to work that way.

Why it becomes a panic

The problem isn't the tax. It's the records.

A Self Assessment built on year-round bookkeeping takes a fraction of the time, costing less in accountancy fees, compared to one built on a reconstruction project. The monster isn't January. It's the twelve months you weren't keeping track.

What actually fixes it

Keep a record of income and expenses as they happen.

That's it. Weekly, fortnightly, whatever you'll stick to. Spreadsheet, accounting software, a notebook. The format matters less than the habit. When January comes, your accounts are already done. You pay what you owe, no more, and get on with the year.

What counts as allowable

This is where sole traders waste hours Googling. Short version:

  • Tools, materials, and equipment used for the trade: yes.
  • Travel to client sites (not commuting from home): yes, mileage or actual fuel costs.
  • Phone and broadband, proportional to business use: yes.
  • Subcontractor costs: yes.
  • Accountancy fees: yes, including this one.
  • Personal shopping, the new sofa: no.

Anything you're genuinely unsure about, ask. That's what the set fee covers.

What disorganised records cost

It's not just stress. If you can't prove you spent the money, you can't claim the expense. You pay more tax than you should. You pay your accountant to do detective work instead of accountancy.

Tidy books mean you keep more of what you earn.
