Catch-Up Bookkeeping in the United Kingdom

We turn months (or years) of backlog into clean, tax-ready financials. Delivered to FRS 102 / UK GAAP for UK businesses, priced in GBP.

Why UK businesses choose Salt

Behind on your books in the UK usually means three things at once: unfiled VAT returns accruing penalties, a Companies House filing deadline approaching, and no idea what the corporation tax bill will be. We work backwards from the deadline that hurts first.

HMRC's points-based penalty regime charges per missed VAT return, and Companies House late filing penalties start at £150 and escalate to £1,500 the longer accounts stay outstanding. The order in which you catch up matters more than the speed.

Catch-up work has to land in MTD-compatible software with an unbroken digital link to the VAT return — a reconstructed spreadsheet cannot be typed into HMRC.

Standards and authorities

The framework your United Kingdom accounts are held to.

We prepare to UK GAAP (FRS 102) or IFRS, as adopted. These are the bodies that set that framework and the authorities you file with — linked so you can verify the standard rather than take our word for it.

Listed for reference. Salt Accounting Group is not stating membership, registration or affiliation with any of these organisations. Where a filing must be lodged by a registered local agent, it is — your agent keeps the lodgement and the professional sign-off.
