How does Tide Accounting calculate my self-assessment estimate?

When you add a category to your transactions, Tide Accounting automatically matches these categories to HMRC’s self assessment SA103 Business Income and Business Expenses categories. This means your Self Assessment estimate is based on your Tide bank account transactions, plus any other transactions you’ve added manually to the estimate. You can connect your business bank accounts from other providers, as well as your Tide accounts, to Tide’s accounting add-ons. This will allow you to view and manage all your accounting and transactions in one place. Read more about the accounting add-ons we offer here.
