Built for Making Tax Digital VAT
MTD-compatible
Submits VAT returns through the live HMRC Making Tax Digital API, with an accepted production submission on file. Listed in HMRC's software-finder process.
Digital-link CSV import
Drop in a CSV with your nine VAT-return box totals. The CSV → submission link is the digital link HMRC requires under MTD — no rekeying, no spreadsheets-to-portal copy-paste.
Connect to HMRC once
OAuth into your VAT account in 30 seconds. Open periods and obligations come back automatically — no chasing reference numbers, no quarterly reauth dance.
Fraud-prevention headers
Every submission carries the full HMRC fraud-prevention header set: device fingerprint, browser plugins, public IP, timezone — exactly as the MTD VAT spec mandates. We update headers as HMRC does.
Multiple VRNs
Filing for several VAT-registered businesses? Add each VRN to your account and switch between them. No separate logins, no separate browsers.
Net VAT refunds
Refund-direction returns (Box 5 negative) are submitted exactly as HMRC expects. Annual accounting scheme, monthly, and quarterly returns are all supported.
Audit trail kept
Every CSV import, request payload and HMRC response is logged against your VRN. Download the trail whenever you need it — for your records, your accountant, or an HMRC compliance check.
UK-built, UK-supported
Built and supported from the UK. Email support hits a real human; no overseas call centres, no chatbots that loop.
How it works
Connect to HMRC. Authorise TinyTax against your VAT account.
Import your figures. Drop in a CSV with your nine VAT-return box values.
Submit. Review, sign and send. HMRC receipt back in seconds.
More Happy. Tiny Tax.
MTD VAT shouldn't need a £30/month bookkeeping subscription you don't want. We're bridging software, not bookkeeping. Bring your nine box totals from a spreadsheet, your accountant, or your existing system — we send them to HMRC under Making Tax Digital with the digital-link audit trail HMRC requires. From £29 a year, scaling to bulk tiers for practices. That's the whole pitch.

Frequently asked questions
Is TinyTax MTD-compatible?
Yes. TinyTax submits VAT returns through the live HMRC Making Tax Digital API and has accepted production submissions on file. We are listed (or actively listing) on HMRC's "Find software for Making Tax Digital for VAT" tool at gov.uk.
What is bridging software, and why do I need it?
Bridging software takes the nine VAT-return box totals from your existing records (a spreadsheet, your accountant's working papers, an older accounts package) and submits them to HMRC under MTD with the digital-link audit trail HMRC requires. You don't need to switch your bookkeeping.
Are quarterly, monthly and annual VAT returns supported?
Yes — all three filing frequencies are supported. The HMRC API tells us which periods are open for your VRN; you pick a period, import the figures, and submit.
Can I file for more than one VRN?
Yes. £29/year covers a single VRN; for accountants, agents and groups, practice tiers cover up to 12 VRNs (£49/year), 50 (£99), 150 (£139), 250 (£165), 500 (£197) or 1000 (£263). Direct VRNs and active agent-client relationships both count toward the same tier — see the pricing page.
What CSV format do you accept?
A simple two-column CSV with each of the nine VAT boxes (Box 1 through Box 9) and a value. An example CSV and the exact column headings are shown inside the app once you connect to HMRC.
Is there a free trial?
You can connect to HMRC, see your open periods and import your figures for free. Payment (from £29/year) is taken before the actual submission to HMRC — you only pay when you're ready to file.
How is this different from Xero, FreeAgent, QuickBooks?
Those are full bookkeeping packages — VAT submission is one feature among hundreds, and they're typically £20–£35 a month. TinyTax MTD VAT is single-purpose bridging software from £29/year. If you already do bookkeeping somewhere else (or in a spreadsheet), this is the gap we fill.
Do I have to switch from my current accounts software?
No. Bring the nine box totals from wherever your numbers live — a spreadsheet, your accountant, an older package. The CSV import is the digital link HMRC requires.
I already pay for CT600 / annual accounts. Do I need a separate subscription for MTD VAT?
Yes — MTD VAT (from £29/year) is a separate subscription from CT600 + accounts (Solo £59/year, Portfolio from £99/year). Subscribe to either, both, or just one.
I'm an agent — does the tier price cover my clients?
Yes. Once a client has authorised you under HMRC's agent-services account, that active relationship counts toward your tier (e.g. 12 active client VRNs fit on the £49 tier, 50 on £99). Pending invitations and revoked relationships don't count.
How do I cancel?
Cancel any time from your account settings. The current paid year stays active; we don't re-bill at renewal once you cancel.
Where do I get help?
Email [email protected] or browse the help centre. UK-based support, real humans, typical reply within a few hours during UK business hours.
