Tax planning

Model your tax position before the year closes.

Important

This is an estimate only. Consult your accountant for formal tax advice. The planner ships rules for 2025/26 and 2026/27 (the current year is 2026/27). Pick an earlier year from the Settings bar to audit historical earnings. Your actual tax position may differ based on other income, reliefs, or circumstances.

What the tax planner does

The tax planning dashboard models your income tax, National Insurance contributions, and pension reserves based on your actual booking earnings. It takes your gross income from recorded bookings, applies your configured expense rate, and calculates the tax you should expect to owe across every relevant band.

The planner updates in real time as you log bookings, so your projected liability stays current throughout the tax year. You can view figures as an annualised projection or as a year-to-date running total. Change the tax year in the Settings bar to re-run the estimate under a different year's rules.

Self-employed sole traders

If your employment type is set to self-employed, the planner calculates:

  • Income tax: applied in bands after your personal allowance (£12,570 for both 2025/26 and 2026/27). Standard rates are 20% basic, 40% higher, and 45% additional.
  • Class 4 NIC: 6% on profits between £12,570 and £50,270, then 2% above that.
  • Class 2 NIC: no longer charged for profits above the Small Profits Threshold (£6,725 in 2025/26, £7,105 in 2026/27). Voluntary contributions are still possible below that threshold to preserve State Pension entitlement, but the planner does not assume voluntary payment.

The planner deducts your configured expense percentage and any fixed annual expenses before calculating taxable profit.

Limited company contractors

If your employment type is set to limited company, the planner models an optimal salary-plus-dividends strategy:

  • Salary: set at the personal allowance level to minimise employer's NIC while using your tax-free band.
  • Corporation tax: 19% on small profits (under £50,000) and 25% on the main rate (over £250,000), with marginal relief in between following the HMRC formula (U − N) × 3/200.
  • Employer's NIC: 15% on salary above £5,000 (the rate rose from 13.8% and the threshold dropped from £9,100 at the start of the 2025/26 tax year).
  • Dividend tax: after the £500 dividend allowance. For 2025/26: 8.75% basic, 33.75% higher, 39.35% additional. For 2026/27 and later: basic and higher rates rose by 2% to 10.75% and 35.75%; the additional rate stays at 39.35%.

Both self-employed and limited company calculations are shown side-by-side on the earnings page so you can compare strategies.

Scottish income tax rates

If your region is set to Scotland in your profile, the planner automatically uses Scottish income tax rates instead of the rUK bands. National Insurance rates remain the same across the UK. Only income tax differs.

2025/26 Scottish bands:

  • 19% starter rate (£12,571 – £14,876)
  • 20% basic rate (£14,877 – £26,561)
  • 21% intermediate rate (£26,562 – £43,662)
  • 42% higher rate (£43,663 – £75,000)
  • 45% advanced rate (£75,001 – £125,140)
  • 48% top rate (above £125,140)

2026/27 Scottish bands (Starter and Basic extended per the Dec 2025 Scottish Budget):

  • 19% starter rate (£12,571 – £16,537)
  • 20% basic rate (£16,538 – £29,526)
  • 21% intermediate rate (£29,527 – £43,662)
  • 42% higher rate (£43,663 – £75,000)
  • 45% advanced rate (£75,001 – £125,140)
  • 48% top rate (above £125,140)

Finance profile settings

You can customise your tax model from your finance profile. The settings that affect the calculation are:

  • Deductible expense rate: a percentage of gross income treated as allowable expenses (e.g. travel, equipment, insurance). Adjust this to match your typical claim rate.
  • Additional annual expenses: a fixed amount for costs like accountancy fees or professional subscriptions that apply regardless of income.
  • Pension contributions: NHS pension tier contributions are factored in automatically based on your annualised earnings. Contributions reduce your taxable income.
  • VAT registration: if you are VAT-registered, the planner adjusts calculations accordingly. Most locums below the £90,000 threshold are not VAT-registered.

Annual vs year-to-date view

Toggle between two views on the tax planning dashboard:

  • Annualised: projects your current earnings rate across the full tax year. Useful for understanding your likely tax band and total liability.
  • Year-to-date: shows actual earnings and tax accrued so far this tax year. Useful for tracking how much you should have set aside already.

What it calculates

  • Gross income: annualised from your actual recorded bookings, using the date span of sessions so sparse workloads don't over-annualise
  • Deductible expenses: adjustable percentage plus fixed annual extras
  • Income tax / corporation tax: HMRC bands for the selected tax year (including Scottish rates)
  • National Insurance: Class 4 (self-employed) or employer's NIC (Ltd). Class 2 is not charged for profits above the Small Profits Threshold.
  • Pension reserves: NHS pension contribution tiers
  • Suggested reserve: how much to set aside for your tax bill

Tier access

Tax planning tools are available on the Basic plan and above.

Frequently asked questions

Why does my tax estimate change when I log a new booking?
The planner annualises your earnings based on all recorded bookings. Adding a new booking changes your projected annual income, which may push you into a different tax band or alter your NIC calculation.
Can I use this for my self-assessment?
No. The planner is a forecasting tool to help you budget for tax payments. It does not replace a self-assessment return. Use it alongside your accountant's advice to ensure you are setting aside enough.
How do I switch between self-employed and limited company?
Update your employment type on your profile page. The tax planner will recalculate automatically using the appropriate model.
Are Scottish rates applied automatically?
Yes. If your region is set to Scotland in your profile, Scottish income tax bands are used. You do not need to enable this separately.
Does the planner account for student loan repayments?
Not currently. Student loan repayments are not included in the estimate. Factor these in separately when budgeting.
