Calculator disclaimer

PAYE calculator

The PAYE calculator estimates regular earnings for the tax year shown on the page. Actual deductions can differ because of cumulative payroll history, benefits, irregular payments, directors' National Insurance, attachments, statutory payments, payroll rounding, an individual's full tax position or later HMRC adjustments.

Stamp Duty calculator

The Stamp Duty calculator covers selected residential, non-residential and mixed-use SDLT rules for England and Northern Ireland. It does not determine whether every relief, surcharge, linked transaction, lease rule, company purchase or special circumstance applies. Scotland uses LBTT and Wales uses LTT.

Self Assessment calculator

The Self Assessment calculator estimates straightforward Income Tax, Class 4 National Insurance, student and postgraduate loan repayments and payments on account from the figures entered. It does not prepare or submit a return and does not cover Capital Gains Tax, foreign income, partnerships, trusts, every property or pension adjustment, trade losses, benefit charges or every interaction between National Insurance classes.

Rates and updates

Rates are checked against the official sources linked from each calculator. Tax rules can change, including after a government announcement or Budget. Always confirm the current rules and the final calculation with HMRC, your payroll provider, conveyancer or an appropriately qualified adviser before acting.

MTD Bridge product preview

The public MTD Bridge product page is an illustrative preview. A private, allowlisted test area can save and correct dummy digital records, connect a dummy user to HMRC's official sandbox, retrieve dummy obligations, send a customer-approved dummy cumulative update and retain summary sandbox receipts.

The test area cannot take payment, use HMRC production, affect a real taxpayer or make a real quarterly update or final declaration. Sandbox acceptance is not HMRC recognition of the product as compatible filing software.

The intended paid product is self-service software supplied by Novo Delta Limited. Novo Delta Limited will not act as the user's tax agent. Users will remain responsible for checking the information displayed, approving submissions and meeting their tax obligations.

No professional relationship

Using a calculator or reading this website does not create an adviser-client relationship with Kanabar Financial. A professional relationship starts only when the scope and terms of an engagement have been agreed.
