Refund Basics

Trusted Partner in Claiming CIS Tax Refunds

Did you know most subcontractors overpay their CIS tax? Almost 20% to 30% of subcontractors’ pay is deducted by their contractors and sent directly to HMRC. The deduction acts as an advance on their annual tax bill. However, in many cases, the deducted amount is more than what is actually owed by subcontractors. This means they are entitled to claim a CIS refund.

At Additions Plus, we help sole traders, partnerships, and limited companies maximise and accelerate their CIS rebates. We have experienced CIS tax accountants who prepare and submit your Construction Industry Scheme refund claim on your behalf. They accurately determine your actual annual tax liability based on your gross income, allowable expenses, and personal allowances. Later, it is compared with the deduction already withheld.

Trust us to handle your CIS refund claim, manage your records, and recover your overpaid funds.

No questions or tasks are too much, they work quickly and efficiently with everything they do. I can’t ask for anything more in help with my accounts.

Additions Plus Where the winning formula equates to the correct answer, All this collated from the a pile of invoices and receipts, resulting with them dealing with the appropriate company(s) with the frightening acromion like H.M.R.C & V.A.T. Leaving me stress free with the acromion that I understand at the end of the week, B.A.R & V.A.T.
