UK tax guides: the answers, without the jargon.

The questions people actually type at midnight, answered properly — by someone who does this for a living, and who checked the rules rather than remembering them.

For limited company directors · 5 min
You pay your Corporation Tax before the return is due — and your first year needs two tax returns. The company deadlines nobody explains properly.

For companies that filed their own return · 5 min
Every 'free CT600 software' search now ends at a paid product. The honest version: what closed, what filing it yourself really costs, and your options.

There is no free CT600 filing software any more — HMRC's service closed on 31 March 2026. What DIY filing really costs, and when it stops being worth it.

For online businesses using Stripe · 7 min
Stripe is sitting on £8,000 of your money. The intuitive answer — no money, no tax — is wrong, and it is wrong on your next VAT return.

For higher earners & the newly retired · 6 min
Between £100,000 and £125,140 you pay 60% tax. Most people earning it have no idea — and there is a legal way out.

Earn over £100,000 and your Personal Allowance is withdrawn £1 for every £2 — an effective 60% tax rate. How a pension contribution buys it back.

For sole traders & landlords over £50k · 5 min
Everyone's scaring you about MTD penalties. HMRC has confirmed there are none this year. Here's what actually matters instead.

MTD quarterly updates fall on 7 August, 7 November, 7 February and 7 May. HMRC has confirmed no penalty points for late updates in 2026-27.

For Shopify & ecommerce sellers · 6 min
Your bank says £70k. HMRC might say £95k. Both can be true — and only one of them matters.

Shopify pays you net of fees, so your bank lags your sales — but the £90,000 VAT threshold is measured on what you sell. How to tell if you've crossed it.
