Honest comparison for UK Ltd directors

Tax Pots Are a Bandaid,
Not a Strategy

Anna Money helps you save money for tax. AccountsOS helps you owe less tax in the first place. There's a difference.

Anna Money is a capable business bank with invoicing and tax pots built in, starting from £11/month. AccountsOS is AI-powered accounting at £20/month (14-day free trial) that works with any bank you already use. The key difference: Anna sets money aside for your tax bill, while Finn, the AI accountant in AccountsOS, helps you legally reduce what you owe through salary optimisation, expense planning, and proactive advice.

The Bank Lock-in Problem

Anna's accounting features only work if you use Anna's bank account. That's not accounting software - that's a feature bundle.

Anna Money

Great invoicing. Clever tax pots. But you're locked into their banking ecosystem.

  • Must use Anna bank account
  • Switch banks = lose your "accounting"
  • New account numbers for all your clients
  • Built for freelancers, adapted for Ltd

Saving for Tax vs. Paying Less Tax

Tax pots are useful for cash flow. But they don't reduce your tax bill - they just help you afford it.

Anna's Tax Pots

What it does: Automatically sets aside a percentage of income for tax.

The benefit: You won't panic when the tax bill arrives.

The limitation: It's a fixed percentage. 19% or 25% of profit goes to Corporation Tax regardless of whether you could legally pay less.

Revenue: £100,000
Tax pot sets aside: £19,000
(No optimization applied)

AccountsOS Optimization

What it does: AI analyzes your situation to find legitimate ways to reduce your tax liability.

The benefit: You actually pay less tax, not just save for a bigger bill.

How it works: Optimal salary/dividend splits, expense maximization, timing strategies, pension contributions.

Revenue: £100,000
After optimization: £12,000-15,000
(£4,000-7,000 saved legally)

The bottom line: Tax pots help you afford your tax bill. Tax optimization helps you shrink it. These are complementary, not the same thing.

When Anna Money Makes Sense

We're not here to trash Anna - it's a good product for certain users. Here's an honest breakdown.

Choose Anna If You...

  • Need a new business bank account anyway
  • Are a freelancer or sole trader (not Ltd)
  • Primarily need invoicing features
  • Want everything in one app (simpler, not smarter)
  • Have an accountant handling the complex stuff

Choose AccountsOS If You...

  • Already have a bank account you like
  • Run a UK limited company
  • Want to actually optimize your tax, not just save for it
  • Need real accounting (P&L, Balance Sheet, VAT)
  • Want the books done, not just a savings pot

Pro tip: Many directors use both - Anna for banking and invoicing, AccountsOS for the accounting intelligence. They complement each other perfectly.

Can I use both Anna and AccountsOS together?

What's wrong with tax pots?

Nothing - tax pots are genuinely useful for cash flow discipline. The problem is they're reactive, not proactive. A tax pot sets aside 20% of your income.

I love the innovative approach to accounting

I love the innovative approach to accounting, which can often be quite dull. I particularly appreciate how interactive it is, including the emails, reminders, and the ability to anticipate the next step.
