Behind on your returns? No lecture. Let's just get it sorted.

Late Self Assessment, CIS refunds never claimed, VAT in a tangle, a carrier bag of receipts, brown envelopes you haven't opened. All fixable, all seen before, nobody's judging.

If HMRC are already writing to you, the worst move is silence, penalties and interest stack while you wait. The second worst is panicking. One message and you'll know what order things need doing in. Costs nothing. WhatsApp or ring 07375 639493.

What sorting it out looks like

1

You send me what you've got

Photos of the letters, the statements, the carrier bag, whatever's there. WhatsApp, in your own time. I'll tell you where you stand, even if you never hire me.

One fixed quote for the catch-up

Based on how far behind and how messy. Agreed before anything starts. Records rebuilt from the bank, statements chased, penalties appealed where there's a case.

Filed, and then it never happens again

Returns in, refund claimed where you're owed one, and lads who are behind on CIS are owed more often than you'd think. Then the monthly service takes over from £69 and every deadline's my problem.

What it looks like once you're straight

One page a month, in English. What came in, what went out, what you made, what to put aside so there's never a brown envelope again. That's the £149 plan. On £69 you get a running total of what HMRC are holding for you instead.

Who's behind it

I'm a career entrepreneur, running operations in private aviation, taxis, agriculture and building projects. I've had small businesses and businesses with turnover over £10m. I loved the numbers side, got great at costings and knowing where the money goes, so I learned bookkeeping and accounting and saw a niche helping trades with their businesses. That's why I set this up. I really enjoy talking to people about their businesses and crunching the numbers. Your business is my business: I won't just send you a list of numbers, I'll break them down and offer suggestions too! It's just me, you have my WhatsApp all the time. Any questions, snags, or want someone to bounce an idea off, give me a shout. More →

Asked by every single person in this situation

Will I get a massive fine?

Late filing penalties are fixed and known — £100 up front for a late Self Assessment, more at 3, 6 and 12 months, plus interest on late tax. The number is almost always smaller than the one keeping you up at night, and filing sooner always shrinks it. Some penalties can be appealed with a reasonable excuse.

I've lost half my receipts. Is it hopeless?

No. Bank statements rebuild most of it, CIS statements can be re-requested from contractors, and sensible reconstruction is normal and accepted. Perfect records aren't the standard — honest, evidenced ones are.

Am I owed a CIS refund?

If you've been on 20% (or worse, 30%) deductions and haven't filed, quite possibly — deductions often exceed what you actually owe. Filing is how you find out. The refund calculator gives you a rough number in thirty seconds.

Will you judge the carrier bag?

The carrier bag is a classic of the genre. Photograph the lot into WhatsApp and it stops being your problem.
