How it works

Simple & Compliant.

You already track your sales somewhere. SimpleTaxLink turns that into an official HMRC submission — in four simple steps.

01

Connect Your Sheet

Paste your Google Sheets link, map your columns once, and you're done.

02

We Validate Everything

Errors caught before they reach HMRC — missing income, date gaps, wrong figures.

03

One-Click Submit

Send your quarterly update straight to HMRC via the official MTD API.

04

Deadline Reminders

We'll ping you before each quarter closes so you're never caught out.

Features

Built for people HMRC software forgot

You're not a big business. You just want to stay compliant without drowning in jargon or paying £100/month for bloated tools.

Transparent Submission Tracking

Every quarterly submission archived with a timestamped receipt. Your full history in one place — ready if HMRC ever asks.

Seamless HMRC Connection

We connect directly to the official Making Tax Digital API. Your data is sent securely over HTTPS and nowhere else.

Free exists. Here's why it's not enough.

HMRC offers a basic free tool. It costs you time, risks costly mistakes, and leaves you guessing how much tax you owe. Here is the full picture.

45+ mins

Manual portal entry every quarter

vs

SimpleTaxLink

~2 mins

Google Sheet connected, one click submit

That is 43 minutes back every quarter — 172 minutes a year. Spend it on your business, not on government portals.

One mistake on HMRC's portal could cost you more than SimpleTaxLink does in a year

  • Late submission penalty: £100 minimum fine for missing a quarterly deadline
  • Incorrect figures: HMRC can issue penalties of up to 30% of unpaid tax for careless errors
  • Missed expenses: every expense you forget to claim is money HMRC keeps that should be yours

SimpleTaxLink validates your figures before anything is sent, reminds you before every deadline, and walks you through your expenses with a pre-submission checklist. For £29 a year it is the cheapest insurance you will ever buy.

FAQ

Honest answers to obvious questions

Nope. Keep using whatever Google Sheet you already have. You just map your columns to the fields we need — takes about 2 minutes the first time.

Our Tax Pot Calculator estimates how much to set aside each month based on your income, the latest UK income-tax bands and Class 4 National Insurance — so there are no nasty surprises come January.
