Common questions.

UK limited companies that qualify as micro-entities under FRS 105 — broadly, turnover up to £632,000, balance sheet total up to £316,000, and an average of 10 or fewer employees (Companies Act 2006 s.384A). You need to be a director of the company you're filing for.

Sole traders, partnerships, LLPs, charities, overseas entities and unincorporated businesses are all out of scope. Companies that don't meet the FRS 105 size thresholds need full FRS 102 or IFRS accounts, which we don't produce. We also don't handle long first accounting periods (over 12 months) — HMRC requires those to be split into two returns, and that flow isn't in the product yet.

No, but it's your call. SimpleReturns is built for directors who want to file themselves. We do the categorisation, the FRS 105 maths and the iXBRL generation; you review every figure before transmission. If you'd feel better with a second pair of eyes, we don't prevent that — you can hand the finalised return to an accountant for sign-off before pressing Submit.

Yes. Submissions go through HMRC's Corporation Tax Online Gateway and the Companies House XML Gateway. We are independent software, not HMRC, not Companies House, and not a regulated accountancy firm. The director's declaration on the sign-off step is what authorises us to transmit on the company's behalf.

A flat £99 per submission, charged via Stripe at the point of filing. One-off, no subscription, no monthly fee, no surprise add-ons next April. Creating an account and starting a return that you don't submit costs nothing.

If the rejection is caused by a scope limitation we should have caught (a company that doesn\'t qualify as a micro-entity, for example), we refund the £99 — that\'s set out in section 8 of the Terms. We don\'t refund where the rejection comes from incorrect information you provided (figures that don\'t match the records, an out-of-date Companies House code, a wrong UTR). We can\'t refund or compensate for HMRC penalties, interest or missed deadlines — that\'s the director\'s statutory responsibility.

You can correct the figures and re-submit at no additional charge, provided the original submission was within twelve months. The £99 covers all attempts to file the same accounting period until one is accepted. We surface the HMRC response in plain English so you know exactly what to fix.

Same — you correct and re-submit without paying again. The most common cause is an out-of-date Companies House Authentication Code; we ask you to re-enter it at the sign-off step on re-submissions for that reason.

Yes. Within 24 months of an HMRC-accepted return for the same accounting period, you can open an Amendment from the dashboard at no extra charge. Companies House accounts amendments aren't bound by the same 24-month window. Amendments replace the prior submission; the original record stays on file with both regulators.

We use third-party large-language models to suggest which FRS 105 line item each of your bank-statement transactions belongs to. The suggestion is advisory only — you review every transaction in the Categorise step, accept or correct each one, and the figure you're shown at Final Review is the figure that gets filed. The AI is a starting point, not the final word.

Once you press Submit, the figures in the return are your figures and the director\'s declaration is your declaration, regardless of how the wizard arrived at them — that\'s set out in section 4 of the Terms. Take the time to read every line before submitting. The wizard surfaces unusual patterns (entertainment expenses, overdrawn director\'s loan accounts, big interest charges) explicitly so you can sanity-check them.

We\'re ICO registered. Every request uses HTTPS, daily Postgres backups are AES-256-GCM encrypted, and production access is restricted to a small number of named engineers under MFA. Bank account numbers and sort codes are redacted before any transaction text reaches our AI providers. The full picture is on the Security page; the lawful-basis breakdown and your UK GDPR rights are in the Privacy Policy.

Yes. The dashboard keeps a downloadable copy of every CT600 and set of accounts we transmit on your behalf, for at least six years after the accounting period. iXBRL, PDF and a plain-English summary are all available.

You can ask us to close your account at any time by emailing [email protected]. We\'ll delete the personal data tied to your login. Filings and supporting records have to stay on file for six years after the accounting period — HMRC requires that, and it applies whether you have an account with us or not. After six years it all goes.
