How-to guides for each part of GoTaxes, answers to the questions we hear most, and how to reach a human.
Getting started
- 1Create a free account with your email — no card needed.
- 2Search for your company by name or number. We pull your accounting period and every filing deadline straight from Companies House.
- 3Add your Corporation Tax UTR (the 10-digit number on letters from HMRC) — it's needed for the tax return, and you can add it later.
- 4That's it. Your dashboard now shows exactly what's due and when.
Filing your accounts and tax return
- 1From the dashboard, press "File this year's accounts & tax" — we pre-fill the accounting period Companies House expects.
- 2Answer the plain-English questions: money in, money out, what's in the bank. Around fifteen questions; your Corporation Tax updates live as you type.
- 3Short-cuts: import last year's figures from Companies House with one click, or upload a trial balance CSV from your bookkeeping app.
- 4Preview the finished documents — the real accounts and computations, exactly as they'll be filed.
- 5Press validate: we run your return through HMRC's own business rules before anything is sent.
- 6Pay for the filing year, then submit. Companies House filing is live (our live package is granted); HMRC submission opens when our software recognition completes — your return is validated and ready. HMRC needs your Government Gateway login; Companies House needs your company authentication code. We use these once, in memory, and never store them.
- 7Receipts (HMRC IRmark, Companies House submission number) are saved to your account.
You'll need: your UTR, a Government Gateway account enrolled for Corporation Tax, and your Companies House authentication code (a 6-character code posted to your registered office).
Using Money (MTD Income Tax)
- 1Subscribe to Money from the Money tab (£7.99/month, cancel any time).
- 2Add an income source: self-employment or a UK property.
- 3Add income and expenses as they happen — describe them in plain English and we pick the HMRC category automatically.
- 4Or paste a bank-statement CSV (date, description, amount) and every transaction is imported and categorised in one go.
- 5Attach receipt photos to expenses so everything is in one place.
- 6The sidebar shows your live tax estimate and the amount to put aside by 31 January; each business shows its next MTD quarterly deadline with running totals.
Using Assist (AI admin)
- 1Subscribe to Assist from the Assist tab (£19.99/month, cancel any time). The AI features are in private beta — they switch on for your account as we roll them out; everything else below works today.
- 2Create a client workspace and pick its module: tax & compliance, tender/bid, landlord, or meeting records. Link it to a company or Money business and the deadlines fill themselves in.
- 3Generate the document checklist — the AI adapts a standard template to this client — then adjust it however you like.
- 4Upload documents (PDF, Word, text or CSV). Each one is read, categorised and summarised, with the checklist item it satisfies suggested.
- 5Press "Check missing documents": every checklist item is marked received, needs review, or missing — with the reason.
- 6Generate a chaser email draft. Edit it, approve it, then send it from GoTaxes with one click (or copy it into your own email) — nothing is ever sent without your explicit approval.
- 7When you're ready to hand over, generate the accountant-ready pack and export it as Word or print-ready HTML.
- 8Ask the folder questions any time — answers cite the exact document (and page) they came from.
Scanned or photographed documents aren't read yet (OCR is coming) — they're flagged for manual review instead. Fair use: 1,000 pages and 300 AI actions per month.
Using the business modules (included with Assist)
- 1Open a client workspace and switch on the modules it needs under "Workspace modules": Company, Contracts, Property, Invoices, Tenders and HR each appear as a tab.
- 2Company: prefill the officer and PSC registers from Companies House, record shareholders, share transactions and dividends (vouchers generated for you), and work through the confirmation-statement checklist — every change is journaled.
- 3Contracts: pick from 13 templates (NDA, consultancy, employment, tenancy and more), answer a short questionnaire, and review the AI draft with its plain-English summary and attention flags. Approve, export to Word, then mark as signed — or create an e-signing link.
- 4E-signing: on an approved document, create a single-use signing link per signer and copy it into your own email. The signer reads the document and signs with a typed name; when everyone has signed, the document locks and you can download the audit certificate.
- 5Invoices: record customers and invoices, see the overdue-first ledger, and draft chasers on a tone ladder (friendly → firm → final). Each draft quotes the statutory late-payment interest you may claim. Statements and payment plans included.
- 6Property: track tenancies with a generated rent schedule, record safety certificates (their renewal dates become deadlines), run the compliance check, and draft arrears letters from the actual payment history.
- 7Tenders: attach the tender pack, extract every requirement into a compliance matrix with citations, draft answers from your reusable answer library, and export the assembled bid as Word.
- 8HR: add employees (an onboarding checklist is seeded automatically, right-to-work first), track holiday allowances, absence and training, and draft offer, reference and other letters.
Everything the modules generate is a draft until you approve it, and module deadlines (certificates, invoices, tenders, right-to-work re-checks) appear alongside your filing deadlines automatically.
Money tax guides — landlords & sole traders
The questions Money customers actually ask, in plain English. Guidance, not tax advice — if your situation is unusual, talk to a professional.
What can landlords claim as expenses?
Letting agent fees, repairs and maintenance, landlord insurance, ground rent and service charges, utilities and council tax you pay yourself, advertising for tenants, and replacing furnishings like-for-like (replacement of domestic items relief). Not the mortgage capital you repay, and not improvements — see the repairs guide below.
Mortgage interest — why it isn't an expense
Since 2020, interest and other finance costs on residential lets can't be deducted from rental profit. Instead you get a 20% basic-rate tax credit on them. In Money, record interest under financial costs and we apply the credit automatically — you'll see it as a separate line in your estimate.
Repairs or improvements? It matters
Fixing, replacing like-for-like or restoring something is a repair — deductible this year (a new boiler of similar spec, repainting, patching a roof). Making something better than it was — an extension, an upgrade to significantly higher spec — is an improvement: not deductible now, but it counts against capital gains when you sell.
Rent-a-room relief: £7,500 tax free
Letting a furnished room in your own home? The first £7,500 of rent per year is tax-free under rent-a-room relief (halved if someone else also receives the income). Mark the property as rent-a-room eligible in Money and we take care of the rest.
What can sole traders claim as expenses?
Stock and materials, business travel (not home-to-work commuting), the business share of phone and internet, insurance, marketing, professional and accountancy fees, bank charges on a business account, subcontractors, and equipment. When in doubt: it must be wholly and exclusively for the business.
Mileage: the simple way to claim your vehicle
Instead of tracking fuel, insurance and repairs, claim a flat 45p per business mile for the first 10,000 miles each year and 25p after that. One number to record per trip — usually the better deal for modest business mileage.
Working from home: the flat rate
HMRC's simplified rate lets you claim £10, £18 or £26 per month depending on whether you work from home 25–50, 51–100 or 101+ hours that month — no receipts or utility-bill apportioning needed.
The £1,000 trading allowance
If your self-employment income is under £1,000 a year it's tax-free and doesn't need reporting. Above that, you can choose the £1,000 allowance INSTEAD of your actual expenses when that's the better deal — our estimate picks whichever saves you more automatically.
Quarterly updates, explained
Making Tax Digital for Income Tax means keeping digital records and sending HMRC a cumulative update each quarter — due 7 August, 7 November, 7 February and 7 May — then submitting your tax return by 31 January. Money covers the whole journey: it keeps the records, shows every deadline, prepares each update's figures, and walks you through year-end adjustments to submitting your tax return (direct filing switches on once HMRC production approval completes).
Payments on account — why your January bill can be double
If your tax bill tops £1,000, HMRC asks for two advance payments towards NEXT year — half on 31 January and half on 31 July. Our 'put aside by 31 January' figure already includes the first one, so there's no surprise.
What records should I keep, and for how long?
Bank statements, invoices, receipts and mileage logs — for at least 5 years after the 31 January filing deadline of the tax year they belong to. Attach receipts to entries in Money and everything lives in one place.
Frequently asked questions
Is GoTaxes right for my company?
GoTaxes covers micro-entities (FRS 105) and small companies (FRS 102 Section 1A) with straightforward affairs. Groups, non-GBP accounts and payroll are out of scope — if your situation is unusual we say so and point you to a professional rather than guess.
Is this tax advice?
No. GoTaxes is filing software with clear guidance. We calculate and file from the figures you provide; we don't advise on your tax position. The same goes for Assist — its AI output helps organise admin work and may require professional review.
Do you store my Government Gateway password?
Never. Gateway credentials and Companies House authentication codes are used once, in memory, for the submission you asked for, then discarded. There is deliberately nowhere in our database to store them.
Where do my deadlines come from?
Directly from Companies House when you add your company, so they're the real statutory dates — not estimates. Corporation Tax dates are derived from your accounting period using HMRC's rules.
What is marginal relief and do I need to work it out?
If your profits fall between £50,000 and £250,000, Corporation Tax tapers between 19% and 25%. You don't need to work anything out — we calculate it automatically and show the saving.
Can I fix a mistake after filing?
Yes. Rejected submissions drop back to draft for you to correct and re-file free. Amended returns for accepted filings are included too.
What does the AI in Assist actually see?
Only the documents you upload to that client's workspace and the structured records (deadlines, checklist, tasks) for that client. Answers always cite their source, and anything the AI isn't confident about is flagged for your review rather than guessed.
Does the AI ever act on its own?
No. Assist organises, drafts and flags. Emails are drafts until you approve them; when you press Send, GoTaxes sends the approved draft on your behalf (or you can copy it into your own mailbox instead). Every action is recorded in the workspace activity log.
Is my data used to train AI models?
No. When the AI features are enabled for your account (they are in private beta), Assist uses Anthropic's Claude via their commercial API, which doesn't use customer data to train models. See our privacy policy for the full picture.
What file types can Assist read?
PDFs with selectable text, Word (.docx), and plain text/CSV/Markdown. Scanned images and photo PDFs are flagged for manual review until OCR support arrives.
When is my MTD quarterly update due?
Quarterly updates are due one month and seven days after each quarter ends (7 August, 7 November, 7 February and 7 May for a standard April–April year). Money shows the next one for each business, with the totals ready to submit.
Can my accountant use GoTaxes with me?
Yes — many users prepare everything and have their accountant glance over the preview before filing. Assist's handover pack is designed exactly for that. A full multi-client agent tier is coming; register interest at hello@gotaxes.co.uk.
Is GoTaxes recognised by HMRC?
Companies House has granted our live filing package after a full test campaign. HMRC recognition is in progress — the engine already passes HMRC's own validation rules offline, and we'll update this page the moment recognition completes.
Do the business modules cost extra?
No — Company records, Contracts, Property, Invoices, Tenders and HR are all included in the Assist subscription. Switch on the ones each workspace needs.
Are the generated contracts and letters legal advice?
No. They're solid standard-terms drafts with plain-English summaries and attention flags, for you to review before use. For high-value, unusual or sensitive matters (dismissals, evictions, court action) have a professional check the document — the drafts themselves tell you when.
How does e-signing work, and is it legally valid?
You create a single-use signing link and send it yourself; the signer types their name to sign, and every step is logged (with an audit certificate you can download). This is a simple electronic signature — generally valid for business agreements in England and Wales — not an advanced or qualified signature, and deeds may need extra formalities.
How do I delete my account and data?
Delete it yourself from your account page (Danger zone → Delete account) — personal data is erased immediately, with filing evidence retained anonymised as the privacy policy describes. Or email hello@gotaxes.co.uk and we'll do it for you.
Still stuck? Talk to a human.
