Tax Summary

LTD Director Tax Summary

How to read your company tax breakdown as a limited company director.

  1. 1Your Tax Summary shows company profit — this is turnover minus allowable business expenses.
  2. 2Corporation Tax is 19% on profits up to £50,000 and 25% on profits above £250,000 (marginal relief applies between).
  3. 3The Director Salary slider lets you adjust how much you take as salary. The optimal salary is £12,570 — this clears your Personal Allowance with zero Income Tax.
  4. 4Dividends are taxed at 8.75% (basic rate) after the £500 dividend allowance. Taking dividends is more tax-efficient than salary above £12,570.
  5. 5Employer NI is 15% on director salary above £5,000 — paid by the company, not you personally.
  6. 6The Total Tax Burden combines Corporation Tax + Income Tax on salary + Dividend Tax. Use the sliders to find the most efficient split.

Landlord Tax Summary

How to read your rental income tax breakdown (SA105).

  1. 1Rental Income is the total rent received during the tax year — enter this in the Tax Summary or via Transactions.
  2. 2Allowable Expenses include letting agent fees, repairs, insurance, and utility bills you pay. Enter them as Expense transactions.
  3. 3Net Rental Profit = Rental Income minus Allowable Expenses. This is what HMRC taxes.
  4. 4Mortgage Interest Relief: since April 2020, mortgage interest is no longer a direct deduction. Instead, you get a 20% tax credit on your finance costs. Enter your annual mortgage interest to see the credit.
  5. 5The total tax shown combines Income Tax on rental profit plus any adjustment from the mortgage credit. You file this on SA105 alongside your main Self Assessment return.
