UK tax estimates
Turn your business records into a starting point for tax review. Explore estimates for UK sole traders and companies in the tax preparation workspace.
Your InvoiceKO account. Your business workspace.
A clearer workflow
The workspace supports UK non-savings, non-dividend Income Tax estimates for the 2025–26 and 2026–27 tax years. Choose the supported year and your tax residence, including Scotland where applicable, before entering income and adjustments.
Trading profit alone may not describe your taxable position. Review other non-savings income, disallowed expenses, capital allowances, trading loss relief and tax already paid. Check whether the Class 4 National Insurance exemption setting applies to your circumstances.
Company tax preparation uses your selected accounting period and recorded figures. Review losses, reliefs, associated companies and other relevant company circumstances before relying on an estimate. The workspace calculation is preparation support, not an HMRC determination.
The sole trader estimate does not cover savings or dividend taxation and is not a complete Self Assessment calculation. Return rounding, additional liabilities and reliefs may change the final result. Review the assumptions and obtain advice for circumstances outside the supported calculation.
Good to know

The sole trader calculation has a Scotland option for supported tax years. Select the correct tax residence before reviewing the estimate.
No. Prepare and review your records, then use the appropriate filing process, an accountant or compatible tax software.
