This calculator will give you a guide to what Levy your organisation may pay in 2026 and 2027
To help you see what your CITB Levy may look like in relation to the 2025 and 2026 Levy Returns, we have produced a simple calculator. This calculator will give you a guide to what Levy your organisation may pay in 2026 and 2027 and how this may look as part of a direct debit (final payment dates to be confirmed).
The 2026 Levy Return form will be posted out in Mid-May and available on the CITB online portal from early May, an email notification will be sent to Levy online users when available.
Use the calculator to estimate the CITB Levy you will pay in 2026/27 based on the 2024/25 tax year (6 April 2024 to 5 April 2025).
The calculator will give you a guide to the Levy you will pay. The actual amount you will pay will be shown on your Levy Assessment you will receive shortly after assessment.
The calculator for 2025 includes the 'Small Business Levy Exemption' if your wage bill (PAYE and Net CIS) is below £150,000 and the 'Small Business Levy Reduction' if your wage bill (PAYE and Net CIS) is between £150,000 and £499,999.

2025 Levy Return, if you have completed this
Monthly HMRC CIS300 or CIS online returns for the 2024 to 2025 tax year
Payroll records for the 2024 to 2025 tax year.

The quick calculation is based on a CIS tax rate of 20%. If you used any CIS sub-contractors that were taxed at 30%, the quick calculation is likely to be higher than the actual Levy you pay. For a more accurate result, use the detailed calculation.
