Budget & Tax Savings Dashboard

Your household budget and your tax pot, in one place.

Two tools UK self-employed people usually track separately, in one workbook: a proper monthly household budget (income vs. actual spend, by category, across the tax year), and a tax savings pot tracker that tells you — using the real 2026/27 Income Tax and Class 4 National Insurance rules — roughly how much to set aside each month so Self Assessment in January isn't a shock.

What's in it

  • Monthly household budget by category
  • Tax savings pot with a monthly target
  • On-track tracker for what you've actually saved
  • Quick-start guide (Word)
