Your complete tax year, brought together

Final Annual Declaration & Tax Return

After your MTD quarterly updates, your Final Annual Declaration completes the year — priced separately, because it must reflect your full income, gains and personal circumstances.

020 3965 9902

Your MTD service keeps your digital records, quarterly reporting and tax estimates current through the year. The Final Annual Declaration is the moment it all comes together into your true, final tax position — employment, dividends, rental income, foreign income, capital gains, crypto, pensions, student loans and more. Because that complexity differs for every person, it is prepared, checked by a qualified accountant and priced separately from the recurring MTD fee.

How we work

Under Making Tax Digital, the four quarterly updates are only progress reports: none of them settles your tax. The Final Declaration is the filing that does — it pulls together every income source, applies reliefs and allowances the quarterly updates ignore, and produces the number you actually owe. It replaces the old Self Assessment return, and it carries the same 31 January deadline and the same penalties.

We price it separately from the quarterly service for one honest reason: the work depends on how complex your affairs really are. A sole trader with one trade is a different job from a landlord with three properties, dividends and foreign income. You get the fee confirmed before we start, every relief checked, and the figures explained in plain English before anything is submitted.

Frequently asked questions

Is the Final Declaration the same as a tax return?

It is its replacement under MTD. The four quarterly updates report raw income and expenses; the Final Declaration adds everything else — other income, reliefs, allowances, adjustments — and calculates the tax due.

When is it due?

31 January after the end of the tax year, the same date Self Assessment always used. The penalty-free grace period announced for early MTD quarterly updates does not extend to this filing.

Why is it priced separately from the MTD service?

Because complexity varies enormously between clients. Charging one blended fee would mean simple cases subsidising complicated ones. You get your quote before work begins.

What happens if I skip it?

Your tax is never finalised, penalties and interest accrue, and HMRC can estimate the liability itself — almost always to your disadvantage.
