CT expense adjustments

Yes — that's exactly what TinyTax is built for. Here's how each part works:

**Importing from Excel**

You can import a trial balance from an Excel (.xlsx) or CSV file. Inside the CT600 form, click **Import Trial Balance** in the P&L section, upload your file, and TinyTax will auto-map the accounts to the right categories (turnover, cost of sales, staff costs, etc.). You can adjust the mapping before confirming. Both P&L and balance sheet figures are populated from the same import.

Your file needs to be structured as a trial balance (account name, debit, credit columns) rather than a formatted set of accounts — see: https://tinytax.co.uk/support/trial-balance-import

**Tax adjustments**

Once your figures are imported, the Tax Computation section has dedicated fields for:

- **Depreciation add-back** — entered in the P&L section; automatically added back in the computation (since depreciation isn't tax-deductible)
- **Disallowable expenses** — client entertaining, fines, etc.
- **Capital allowances / AIA** — deducted from taxable profit in place of depreciation
- **Other tax adjustments** — a catch-all for anything else (positive or negative)

These all feed into Box 155 (Tax-Adjusted Trading Profit) on the CT600. More detail here: https://tinytax.co.uk/support/ct600-tax-adjustment-boxes

**CT600 and micro-entity accounts**

TinyTax generates both the CT600 (for HMRC) and micro-entity accounts (for Companies House) from the figures you enter. If you choose "CT600 + Accounts" when starting the filing, both are prepared and can be submitted together. The accounts filed at Companies House are filleted micro-entity accounts (balance sheet only — no P&L is made public).

Since you already have PS:PLANET LIMITED on your dashboard, you can start a filing for it and try the import to see how it looks — you only pay when you're ready to submit.
