How long does it take to register a limited company through Tide?

It depends. In many cases, Companies House will incorporate your company within 1 business day. The majority of businesses are incorporated within 48 hours. Please note that Companies House does not work on weekends so if you send an application on a Friday, it will take longer.

Cash VAT Scheme

You pay VAT to HMRC when you receive payments from customers, and reclaim VAT when you pay suppliers. Your VAT liability will be calculated based on transactions only, and not on invoices.

Standard VAT Scheme 

Your VAT liability is based on invoices & transactions. You pay VAT when you issue an invoice and reclaim it when you receive an invoice from a supplier, regardless of when the payment is made. If there is no invoice for a payment that includes VAT, this payment will still be included in your VAT report – contributing to your VAT liability or reclaim.

It's mandatory to match all invoices to the respective transactions, to ensure correct reporting.
