Honest answers

Frequently asked

I'm only a few weeks late — should I just file it myself?
You can, but the £100 late filing penalty applies even if you owe £0 — and HMRC adds £10/day after three months. We file the same day for £79, which usually pays itself back in deductions you'd miss.
Can you handle CIS sub-contractor refunds?
CIS is a big chunk of our SA work. Average refund we recover is £600–£1,800. We claim back over-deducted CIS tax and apply expenses HMRC let you off (mileage, tools, PPE, training).
I haven't filed for 3 years. Am I in trouble?
Probably less than you think. We'll file all overdue years at once, calculate the realistic total of penalties, and where possible argue them down (HMRC accepts "reasonable excuse" more often than people realise).
Do you do crypto / shares / capital gains?
Yes — we'll work from your exchange CSVs (Coinbase, Binance, Kraken) and broker statements (Trading 212, Hargreaves Lansdown, IBKR). We compute the gain, apply your annual exemption and bed-and-breakfast rules.
What if I owe more than I expected?
If you can't pay it all at once, we'll set up a Time to Pay arrangement with HMRC at no extra charge. Most are agreed within a week.
