Quick answer
Yes. HMRC’s list of software that works with MTD for Income Tax includes some free products. HMRC doesn’t provide its own free app, so you need a third-party product. Free options often have conditions, such as limits on income, features or the number of businesses, so check they cover quarterly updates and the final declaration.
Where to find free options
HMRC’s software finder on GOV.UK lets you filter recognised products by feature. Some providers offer a free version, and some banks include free bookkeeping software with a business account.
What to check
Does it support all your income: self-employment, UK property, overseas property?
Does it do both quarterly updates and the final declaration?
Are there limits on income, transactions or the number of businesses?
Is it free permanently, or only for an introductory period?
Can you export your data if you switch later?
Free with spreadsheets
If you already keep a spreadsheet, a free or low-cost bridging software product may be all you need.
