Entering Zero Figures: Why Fields Show as Blank

Why Zero Fields Show as Blank

When you enter `0` into a number field in TinyTax, the field will display as blank after you move away from it. This is expected behaviour — blank and zero mean the same thing in every numeric field.

TinyTax displays number fields as blank when they are zero to keep the form clean and easy to scan. When your filing is calculated and submitted, blank fields are treated as zero. You do not need to enter `0` — leaving a field blank achieves exactly the same result.

Filing for a Company with No Profit

If your company had no trading activity during the period — no sales, no invoices, no revenue — you simply leave the Profit & Loss fields blank. The filing will correctly show nil turnover and nil profit.

What to Enter

Profit & Loss section: Leave all income and expense fields blank (they default to zero). No turnover, no expenses, no profit.

Balance Sheet — Current Assets: If your company has money in the bank, enter that amount in the Cash at bank and in hand field. For example, if you have £100 in the company bank account, enter `100`.

Balance Sheet — Shareholders' Funds: Your balance sheet must balance — assets must equal liabilities plus equity. If the only asset is £100 cash and there are no liabilities, your shareholders' funds should also be £100. This is typically made up of:

• Share capital — the amount paid in when the company was formed (e.g. £1 or £100)
• Retained earnings / profit and loss reserve — any accumulated profit or loss (may be zero or a small negative figure from bank charges)

If your share capital was £100 and you've had no income or expenses, enter £100 in share capital and leave retained earnings blank.

Is My Company Dormant?

A company may qualify as dormant if it has had no significant accounting transactions during the period. HMRC's definition allows small amounts (such as bank charges or the original share issue) without making the company non-dormant.

If your company's only asset is the original share capital you paid in, and you've had no other transactions, you may be able to file as Dormant — which uses a simplified form.

If you have had any transactions beyond the initial share subscription (e.g. the company received or spent money for any reason), file as a Trading Company with nil profit instead.

Common Questions

I entered 0 and it disappeared — did my data get saved?

Yes. The blank display is cosmetic. Your figure is saved as zero and will appear correctly in the CT600 preview.

My balance sheet does not balance — what do I do?

Check that your Total Assets equals your Total Shareholders' Funds (plus any liabilities). Common causes of imbalance:

• Share capital not entered
• Prior year figures missing or incorrect
• Retained earnings not matching the accumulated profit/loss
