Statement Analyser

Monzo, Barclays, HSBC, Chase, Slash. We parse, categorise, and reconcile to the penny — then output SA100, CT600, SA800 and Form 5472 totals.

Multi‑entity

Each entity on its own books

Personal, Ltd, partnership, LLC — never mixed. Director's loan account and inter‑company balances tracked openly, kept out of P&L.

AI Tax Advisor

Ask, with your structure as context

Claude‑powered. Knows your entities, your bank accounts, the rules table for the year you're asking about. No more generic forum advice.

Crypto

Disposals, swaps, staking — all categorised

Pull from exchange exports, match to UK CGT rules and the right annual exempt amount, then drop straight into your SA100.

Quick compare

Net income calculator that respects bands

Sole trader vs Ltd dividend split vs salary‑plus‑pension. NI, dividend tax, pension AA taper — all priced in for your year.

The pitch, in one go

Most accounting tools pretend a single sole‑trader spreadsheet is the world. AccountMaxing was built for the rest — owner‑operators with a Ltd, a partnership, a US LLC, foreign income, crypto, and four bank accounts. Set up your entities once. Upload statements as they come in. We file them against the right return.

Stop running your tax life out of three different spreadsheets.
