How to Save for Your Stamp Duty Bill as a First-Time Buyer
A complete funding plan for first-time buyers: how much you actually need, how long it takes to save it, the strategies that get you there faster, and the timing rules that catch buyers out. If you need the exact bill, use the FTB stamp duty calculator.
Key Takeaways
- •If your purchase is under £300,000, your stamp duty target is £0 — redirect every spare pound to the deposit instead
- •Between £300,000 and £500,000 you need to save up to £10,000; most FTBs accumulate this in 12–24 months alongside their deposit
- •Hold SDLT money in a separate easy-access savings account, not your deposit ISA — you need it on completion day
- •A Lifetime ISA cannot pay your stamp duty directly, but its 25% government bonus frees up other savings to cover it
- •Stamp duty is due to HMRC 14 days after completion; your solicitor pays it from funds you transfer on completion day

How Much You Need to Save
Your savings target depends entirely on price. Most first-time buyers fall into one of three brackets:
Under £300,000
£0
No SDLT to save for. Put everything toward the deposit.
£300,001 – £500,000
Up to £10,000
5% on the portion above £300,000. Plan a separate savings pot.
Above £500,000
£15,000+
FTB relief is lost entirely — you pay standard rates on the whole price.
Cliff edge at £500,000: A property at £500,000 costs an FTB £10,000. At £501,000 the bill jumps to £15,050 because relief disappears entirely. If your offer is just above £500,000, negotiating it down typically saves more than £5,000 on stamp duty alone.

Savings Timeline at Common Property Prices
The table below shows how long it takes to save the required SDLT at different monthly savings rates for the most common first-time buyer price points.
| Property | FTB SDLT | £250/mo | £500/mo | £750/mo | £1,000/mo |
|---|---|---|---|---|---|
| £250,000 | £0 | — | — | — | — |
| £300,000 | £0 | — | — | — | — |
| £325,000 | £1,250 | 5 months | 3 months | 2 months | 2 months |
| £350,000 | £2,500 | 10 months | 5 months | 4 months | 3 months |
| £400,000 | £5,000 | 20 months | 10 months | 7 months | 5 months |
| £450,000 | £7,500 | 30 months | 15 months | 10 months | 8 months |
| £500,000 | £10,000 | 40 months | 20 months | 14 months | 10 months |
Green rows = zero SDLT. FTB relief applies on all rows up to £500,000. Assumes savings start from zero.
Your Total Upfront Cost
Stamp duty is one line on a longer bill. To plan honestly, treat the whole completion-day total as your funding goal — not just the deposit. Here is what a typical first-time buyer needs ready on completion day for a £400,000 purchase with a 10% deposit:
| Cost | Amount | Notes |
|---|---|---|
| Deposit (10%) | £40,000 | Higher deposits get better mortgage rates |
| Stamp duty (FTB) | £5,000 | 5% on the £100k portion above £300k |
| Solicitor / conveyancing | £1,500–£2,500 | Includes searches and Land Registry fees |
| Mortgage product fee | £0–£1,000 | Often added to the loan, but check |
| Survey (homebuyer) | £400–£800 | Paid before exchange, not on completion day |
| Removals + first-month bills | £1,000–£2,000 | Easy to forget until the keys are in your hand |
| Total funding goal | £48,000–£51,300 | Plan against this, not just the deposit |
The £5,000 stamp duty bill looks small next to the deposit, but it is the line item most likely to be forgotten until the solicitor's completion statement lands. Build it into your savings plan from day one.
Where Stamp Duty Actually Bites: Regional Reality
The FTB savings calculator tells a very different story depending on where you buy. Average first-time buyer prices vary enormously across the UK, which means the stamp duty challenge is far greater in London and the South East.
London
Avg FTB price: ~£450,000
SDLT: £7,500
~15 months at £500/mo
Midlands
Avg FTB price: ~£220,000
SDLT: £0
No saving needed
North England
Avg FTB price: ~£165,000
SDLT: £0
No saving needed
First-time buyers in the North of England, the Midlands, Wales, and Scotland buying at typical local prices often face no SDLT at all. The challenge is almost entirely a London and South East problem, where average FTB prices regularly exceed the £300,000 nil-rate threshold by £100,000 or more. If you are buying in an area where average prices sit below £300,000, you can redirect your entire savings effort toward the deposit.
Strategies to Save Faster
Once you know your SDLT target, these strategies can help you reach it faster:
High-interest easy-access savings account
Keep SDLT savings in a separate high-interest account (currently 4–5% AER from leading banks). This keeps it liquid for completion day while earning meaningful interest. Do not lock it in a fixed-term bond, as you need access when your purchase completes.
Lifetime ISA (LISA): indirect benefit only
LISA funds cannot pay stamp duty directly (they can only go toward the purchase price), but the 25% government bonus frees up other savings for SDLT. See our LISA strategy guide for the full explanation.
Cash ISA for deposit, savings account for SDLT
Max out your Cash ISA allowance (£20,000/year) for your deposit savings, as tax-free interest adds up. Hold your SDLT fund in a standard savings account where you might earn slightly less but can access it freely without ISA rules complicating things.
Help to Save (if eligible)
If you are on Universal Credit or Working Tax Credit, the government's Help to Save scheme gives a 50% bonus on savings up to £50 per month (£1,200 bonus over 4 years). While modest, it is a guaranteed return available to lower-income first-time buyers.
Keep SDLT Savings Separate from Your Deposit
One of the most common financial mistakes first-time buyers make is pooling their deposit savings with their SDLT fund. The problem: as your property search progresses and you find a property you love, the temptation to use "all available savings" for the deposit can leave you scrambling to find stamp duty funds on completion day.
Worked Example: Completion Day Surprise
Emma has £55,000 saved. She buys a £400,000 property with a 10% deposit (£40,000). She expects her stamp duty to be £5,000 as a first-time buyer. Her solicitor confirms she needs £40,000 deposit + £5,000 SDLT + £2,500 legal fees = £47,500 total on completion day.
Because she had labelled her savings "deposit fund," she nearly committed £40,000 to the deposit without ring-fencing the £7,500 needed for SDLT and fees. She narrowly avoided needing an emergency personal loan by catching this with her mortgage broker three weeks before completion.
Open a dedicated savings account for your SDLT and legal fees. Label it clearly. Do not touch it for the deposit. When you exchange contracts (typically 4–8 weeks before completion), your solicitor will give you the exact completion statement: this is when you confirm the final SDLT amount.
Employer Schemes and Family Help
Beyond personal savings, first-time buyers have two additional funding sources worth exploring: employer schemes and family gifts.
Employer Home Buying Schemes
Some employers (especially in financial services, tech, and public sector) offer home-buying assistance as a benefit. These can include interest-free loans, salary advances, or matching schemes specifically for deposit or home-buying costs. Check your employee benefits portal or speak to HR, as this is an underutilised benefit. Any employer loan is usually structured as a salary deduction arrangement, with HMRC implications if the interest rate is below the official rate.
Family Gifts for Stamp Duty
Parents and family members can gift money specifically for stamp duty. Unlike a gifted deposit (which lenders scrutinise closely and require a declaration for), a gift toward stamp duty is not subject to lender oversight, as SDLT is paid directly from your own funds after completion, not through the conveyancer. See our full guide to parents paying stamp duty for the IHT implications and structuring options.
Quick Summary: Stamp Duty Timeline
- Exchange of contracts: Solicitor confirms exact SDLT amount
- Completion day: SDLT funds transfer with balance of purchase price
- 14 days after completion: Solicitor files SDLT return and pays HMRC
- Penalty for late payment: Interest charged from day 15 at HMRC rate
