Notification deadline
Takes the earlier of 30 days from the buyer's decision and the relevant date (completion), so one date is left on screen instead of two half-remembered rules.
TOGC holds or fails
Checks the two things that actually break a TOGC on opted land: the buyer's option notified to HMRC by the relevant date, and the Article 5(2B) notice given to the seller.
SDLT charged on the VAT
Runs the non-residential bands (0% / 2% / 5%) twice - on the price and on the VAT-inclusive consideration - so the permanent SDLT uplift is visible, not assumed away.
Irrecoverable VAT
Applies the buyer's recovery percentage, so a partly exempt buyer sees the share of the VAT that never comes back.
Cost of funding the VAT
Charges the recoverable VAT at the buyer's borrowing rate for the months until the repayment lands.

Questions people ask

What does this actually work out?

It prices a failed transfer of a going concern on opted UK commercial property. You enter the price, the decision and completion dates, whether the buyer's option was notified and whether the seller got the Article 5(2B) notice. It returns the notification deadline, the VAT, both SDLT figures, the permanent SDLT uplift and the funding cost.

Who is it for?

Conveyancers and property solicitors in England and Northern Ireland, in-house property accountants, and buyers of opted commercial units, offices and warehouses. Anyone who has to answer the question a client asks at exchange: if this notice slips, what does it cost us, and by which date must it be with HMRC?

Why is a free SDLT calculator not enough?

Free SDLT calculators take a single price and stop. They never ask whether VAT lands on that consideration, so they cannot show the uplift, which is the part nobody budgets for. They also ignore the option-to-tax clock and the seller notice, which are what decide whether VAT applies at all.

What is free and what needs the key?

Every calculation is free, in full, with no key, no watermark and no usage limit: deadline, verdict, VAT, both SDLT figures, irrecoverable VAT and funding cost. The $60 key adds two things on a different axis: a .csv row you keep in the transaction file, and alarms 30, 14 and 1 days before the deadline.

What would this cost from an adviser?

UK VAT specialists bill roughly GBP 250-400 an hour, and a TOGC or option-to-tax review is rarely a sub-hour job, so a single second opinion on one deal costs more than the key. The extension does not replace advice on a difficult title; it stops the arithmetic being the thing that goes wrong.

Where do the rules come from?

The option-to-tax notification window and the TOGC conditions are in HMRC VAT Notice 742A and the VAT (Special Provisions) Order 1995, Article 5. The bands are the England and Northern Ireland non-residential SDLT rates: nil to GBP 150,000, 2% to GBP 250,000, 5% above. Scotland and Wales use LBTT and LTT instead.
