WHAT IT COVERS

Four areas of your return, calculated together.

Your income tax and capital gains affect each other, so Mova Tax works them out as one position rather than four separate sums.

Capital Gains Tax

Shares, funds and crypto, with same-day, 30-day and Section 104 pooling rules applied the way HMRC expects.

Income Tax and NI

Employment, dividends, savings and foreign income, stacked in the right order, with Gift Aid, pension contributions and EIS, SEIS and VCT relief.

Property income

The £1,000 property allowance or your real expenses, and the 20% finance cost credit for mortgage interest.

Side income

Self-employment profit with the £1,000 trading allowance or actual costs, feeding Class 4 National Insurance.

SMART PLANNING

It doesn't just report last year. It helps you plan the next one.

Mova Tax watches for the cliff-edges that quietly cost people money, and works out what it would take to avoid them.

01
£100,000 – £125,140

The 60% trap

Between these figures your Personal Allowance is withdrawn, so each extra pound is taxed at an effective 60%. See it coming and see the way out.

02
£60,000 – £80,000

Child Benefit charge

Spot the High Income Child Benefit Charge early, and see how much pension or Gift Aid it would take to bring your income back under the line.

03
WHAT IF

Try it before it happens

Model a bonus, extra freelance income, a share sale or a pension contribution, and compare scenarios side by side, such as selling before or after 5 April.

WHERE WE ARE

Being built in the open, one careful step at a time.

Tax is the one area where being right matters more than being fast. Here is honestly what exists today and what is coming.

01
BUILT AND TESTED

The calculation engine

Income Tax, National Insurance, Capital Gains Tax with Section 104 pooling, property and trading allowances, and the planning tools above, checked against hand-worked cases.

02
IN BUILD

Your account and saved figures

Sign in, build up your figures across the tax year rather than re-entering them, and keep them private to you. Entry for share and crypto transactions follows.

03
LATER

Import and tax packs

CSV import from brokers, and a tax pack with box-mapped figures and workings you can hand to an accountant.
