Levy calculator

To help you see what your CITB Levy may look like in relation to the 2023 and 2024 Levy Returns, we have produced a simple calculator. This calculator will give you a guide to what Levy your organisation may pay in 2024 and 2025 and how this may look as part of a direct debit (final payment dates to be confirmed).

The 2024 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.

The Levy rates for the 2023 & 2024 Levy Assessment are 0.35% for PAYE and 1.25% for Net CIS, however the 'Small Business Exemption' and 'Small Business Reduction' thresholds have changed. See 2024 Levy Return information below for more on this.

CIS sub-contractors Cynllun y Diwydiant Adeiladu

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.

Mae'r cyfrifiad cyflym yn seiliedig ar gyfradd dreth o 20%. Os gwnaethoch ddefnyddio unrhyw is-gontractwyr a gafodd eu trethu 30%, mae'r cyfrifiad cyflym yn debygol o fod yn uwch na'r hyn y byddwch yn ei dalu mewn gwirionedd. Er mwyn cael canlyniad mwy cywir, dylech gyfrifo'ch Lefi'n fanylach.

Total CIS tax deducted from sub-contractors

You can find this on your Levy Return in section 3, box C.

If you haven't completed your Levy Return, add together the CIS tax deductions from your monthly HMRC CIS returns.

The quick calculation gives a guide to the Levy you pay on sub-contractors. This is how it works out the calculation:

1) It multiplies the CIS tax deducted by 5.
2) This results in the gross payment to CIS sub-contractors, based on a CIS tax rate of 20%.
3) It applies the CITB Levy to this gross payment.

Cyfanswm y dreth a ddidynnwyd o dal is-gontractwyr o dan Gynllun y Diwydiant Adeiladu

Mae hwn i'w weld yn Adran 4, Blwch C o'ch Ffurflen Lefi.

Os nad ydych wedi llenwi'ch Ffurflen Lefi, adiwch at ei gilydd y didyniadau treth a nodwyd ar y ffurflenni a anfonwyd i CThEM bob mis.

Mae'r cyfrifiad cyflym yn rhoi syniad i chi o'r Lefi y byddwch yn ei dalu ar gyfer is-gontractwyr. Dyma sut mae'n ei gyfrifo:

1) Mae'n lluosi'r dreth a ddidynnwyd a 5.
2) Y canlyniad yw'r taliadau gros a wnaed i is-gontractwyr ar sail gyfradd dreth o 20%.
3) Mae'r ffigur hwn yn agored i'r Lefi.

Total payments to CIS sub-contractors

You can find this on your Levy Return in section 3, box F.

If you haven't completed this box on your Levy Return, use your monthly HMRC CIS returns to work out the amount, like this:

1) For each month, add together the total payments before deductions to all sub-contractors you have deducted CIS tax from.
2) For each month, add together the cost of materials paid for by each subcontractor you have deducted CIS tax from.
3) Deduct the total cost of materials (step 2) from the total payments to sub-contractors (step 1) for each month.
4) Add together the 12 monthly totals and enter this figure in the detailed calculation box.

Cyfanswm y taliadau a wnaed o dan Gynllun y Diwydiant Adeiladu i is-gontractwyr

Os nad ydych wedi llenwi'r blwch hwn ar eich Ffurflen Lefi, defnyddiwch y ffurflenni a anfonwyd i CThEM bob mis i gyfrifo'r swm, fel hyn:

1) Ar gyfer pob mis, adiwch at ei gilydd gyfanswm y taliadau cyn didyniadau a wnaed i bob is-gontractiwr rydych wedi didynnu treth oddi wrtho.
2) Ar gyfer pob mis, adiwch at ei gilydd gostau'r deunyddiau y mae pob is-gontractiwr rydych wedi didynnu treth oddi wrtho wedi talu amdanynt.
3) Tynnwch gyfanswm cost y deunyddiau (cam 2) o gyfanswm y taliadau a wnaed i is-gontractwyr (cam 1) ar gyfer pob mis.
4) Adiwch at ei gilydd gyfansymiau'r 12 mis a rhowch y ffigur hwn yn y blwch.
