FAQs About CIS TAX Returns in London

[/accordion-item]
When are CIS returns due?

CIS returns must be submitted by the 19th of each month following the tax month. Late returns may incur penalties.

Do subcontractors have to submit CIS returns?

No. Subcontractors do not file returns but must ensure deductions are recorded accurately and can reclaim overpaid tax through their annual return.

How do I know if my work qualifies under CIS?

If your work falls under construction, repair, demolition, or related services in the UK, it likely qualifies. We’ll assess your situation and advise accordingly.

I met with Naeem from Interface Accountants in their office, nestled within the serene campus of Botanica Ditton Park, a perfect setting for discussing accountancy matters! The peaceful surroundings created a calming atmosphere, unlike any other place I’ve met an accountant. Meeting Naeem was a breath of fresh air following frustrating enquiries with online and offline-based accountants. He was as calm as his surroundings, attentive, polite, professional and highly knowledgeable, offering immediate practical assistance and helpful insights. I’m delighted to have connected with Naeem and Interface Accountants, and look forward to using their services!
