What this page helps with
Best for people who need careful review before sending figures to HMRC. This is not a simple instant-quote situation.
How Taxcandid can help
Start with the part that matches your situation, then use the right action button when you are ready.
Read the letter properly
The wording, deadline, tax years and information requested affect the safest response.
Rebuild the facts
Income sources, bank records, previous returns and missing years need to be matched before figures are sent.
Disclosure route
Where income was missed, the right disclosure approach depends on whether HMRC has already contacted you.
Reduce mistakes
A careful response is usually better than sending rushed figures or making assumptions.
Practical support
Sensitive tax problems need a calm plan
People often leave HMRC letters because they are worried, embarrassed or unsure what the letter means. The worst approach is to ignore deadlines or send incomplete figures just to get it over with.
Taxcandid helps by reviewing the letter, income sources and records first. Once the facts are clear, the response, disclosure route and fee can be agreed properly.

Questions people ask
Should I use the quote generator for an HMRC investigation?
No. HMRC letters, undeclared income and investigations should start with contact because the fee depends on the tax years, records, deadlines and risk.
Can Taxcandid help before HMRC contacts me?
Yes. If you realise income was missed, it is usually better to review the position before HMRC writes again.
Should I send all documents straight away?
Send the letter and a brief explanation first. Do not send unnecessary sensitive documents until Taxcandid confirms what is needed.
Can you guarantee the outcome?
No accountant can guarantee HMRC’s decision. Taxcandid can help you prepare a careful, accurate and organised response.
